Missed Reporting Investment Account: Collars and Forwards
Missed reporting investment account hedges? See how collars and prepaid forwards are reported on US and UK returns and how to catch up. Speak to our team.

A coin stack sealed under glass: a collar or prepaid forward protects one large shareholding, and each country reports the hedge differently.
A collar or prepaid variable forward over a single stock is reportable in both countries even when no share is sold. For a UK-resident American, a Missed reporting investment account problem usually means the hedge was left off Form 6781, Form 8949, Form 8938, the FBAR and the UK capital gains pages. Each can be corrected.
The reason these positions go unreported is rarely concealment. A founder or senior executive with most of their wealth in one company's shares signs derivative documentation with a bank, no shares leave the account, no cash gain appears on a statement, and the year-end tax pack is silent. Yet the United States and the United Kingdom each attach consequences to the hedge from the day it is signed, and they attach different consequences on different dates. This guide explains how a collar and a prepaid variable forward are reported on each return, where the two returns disagree, and how earlier years are caught up. It is a return-preparation guide. It does not address whether a hedge should be entered into or how one should be designed.
What exactly has to be reported?
Two structures account for most of the cases we see.
- A protective collar. The shareholder buys a put option over the shares, which sets a floor, and sells a call option over the same shares, which sets a ceiling. The premium received on the call often pays for most or all of the put. Both options are usually over-the-counter contracts with a bank, not exchange-traded contracts.
- A prepaid variable forward. The shareholder receives a cash payment now, typically a large fraction of the current value of the shares, and agrees to deliver a variable number of shares, or their cash value, at a date some years ahead. The number of shares delivered falls as the share price rises between a floor and a cap. The shares are pledged as collateral.
Neither structure looks like a sale to the person who signed it. For tax purposes each creates several separately reportable items:
- the options or the forward contract as assets in their own right;
- a change in the tax attributes of the shares themselves, on the US return;
- the premium paid and received, in different years in each country;
- the custody or collateral account as a foreign financial account; and
- any UK tax, which must be matched to US tax through the foreign tax credit.
How does the US treat a collar over appreciated stock?
Four separate sets of US rules apply at once. General-audience articles normally cover the first and stop.
1. Is the collar a constructive sale under section 1259?
Section 1259 treats certain hedges of an appreciated position as a sale at fair market value on the day the hedge is entered into, even though the shares are still held. The statute lists a short sale of the same or substantially identical property, an offsetting notional principal contract, and a futures or forward contract to deliver the same or substantially identical property. A forward contract for this purpose means a contract to deliver a substantially fixed amount of property for a substantially fixed price.
A collar is not on that list. The statute instead authorises regulations to reach other transactions with substantially the same effect, and the legislative history identifies collars as the intended target. Those regulations have never been issued. The practical position is therefore:
- there is no published bright-line band between the put strike and the call strike that is officially safe or officially fatal;
- a collar that removes substantially all risk of loss and opportunity for gain is exposed to constructive sale treatment, and one that leaves meaningful exposure in both directions generally is not treated as a constructive sale by preparers;
- the width of the band, the term, and what else the shareholder has done with the shares are all facts the return preparer needs before deciding how to report.
Rules of thumb circulate in practice. They are conventions, not law, and a return should not cite one as if it were authority.
Where a constructive sale has occurred, the reporting is specific. Gain is recognised as if the shares were sold at fair market value on that date and immediately repurchased. It is entered on Form 8949 and Schedule D for that year. The basis of the shares is increased by the gain recognised, and a new holding period begins. Only gain is accelerated; a constructive sale never triggers a loss. A narrow exception applies where the hedge is closed shortly after the year end and the shares are then held unhedged for a minimum period. The same section is the reason a short sale against shares already held is no longer a deferral technique, a subject covered in our separate guide to short selling for UK-resident American investors.
2. The straddle rules in section 1092
Even a collar that is comfortably outside section 1259 is almost always a straddle. Shares and options over those shares are offsetting positions, because holding one substantially diminishes the risk of loss on the other. Three consequences follow, and all three affect what goes on the return.
- Holding period. If the shares had not yet been held for the long-term holding period when the collar was entered, the holding period already accrued is eliminated and does not begin again until the straddle ends. Shares already held long-term keep that status.
- Loss deferral. A loss realised on one leg is deductible only to the extent it exceeds the unrecognised gain in the offsetting positions at the end of the year. For a founder whose shares have a very low basis, unrecognised gain in the shares will dwarf any loss on a lapsed put. The loss is carried forward year after year until the shares are disposed of.
- Loss character. Where the shares were already long-term when the straddle was established, a loss on the option leg is generally treated as a long-term capital loss, whatever the holding period of the option.
An identified straddle election changes the mechanics: a loss on one leg is added to the basis of the offsetting position instead of being deferred. The identification has to be made in the taxpayer's records by the close of the day the straddle is acquired. Whether it was made is a question of fact for the preparer to establish from the file. It cannot be created retrospectively.
One further point is often missed. The exemption for a qualified covered call, which we explain in our guide to covered call writing, does not apply where the call is part of a larger straddle. A call sold as one leg of a collar is therefore inside the straddle rules, however conservative its strike price.
3. Capitalised carrying costs under section 263(g)
Interest and carrying charges properly allocable to property that is part of a straddle are not deductible. They are added to the basis of the position. If the shareholder has borrowed against the collared shares, the interest on that borrowing is the usual item caught. On the return this means an investment interest deduction that should not have been claimed, and a basis schedule for the shares that should have been increased. Both need correcting if earlier years ignored the rule.
4. Dividends lose qualified status
A dividend is taxed at long-term capital gains rates only if the shares are held for more than 60 days in the 121-day period that begins 60 days before the ex-dividend date. Days on which the holder has an option to sell the shares, is under a contractual obligation to sell them, or has otherwise diminished the risk of loss do not count. A put held throughout that window means no days count. Dividends received on collared shares are therefore generally ordinary dividends on the US return, taxed at rates up to 37% instead of a maximum of 20%, however many years the shares have been owned. Dividends from the underlying company are frequently reported by the payer as qualified, because the payer cannot see the hedge. The return has to override that.
How are the option premiums reported at lapse, exercise or close?
Section 1234 governs the options themselves. Nothing is reported when the premium is paid or received. The position stays open until one of the following events.
- The put lapses. The premium paid is a capital loss on the expiry date, subject to the straddle deferral and character rules above.
- The put is exercised. The premium paid reduces the amount realised on the shares delivered. There is no separate loss.
- The call lapses. The premium received is a short-term capital gain on the expiry date, regardless of how long the call was outstanding.
- The call is exercised. The premium received is added to the amount realised on the shares delivered.
- Either option is closed or cash-settled early. The difference between the premium and the closing payment is capital gain or loss on the closing date. For the written call it is generally short-term.
This produces an asymmetry that surprises most people who entered a so-called zero-cost collar. If both options expire unexercised, the call premium is taxable short-term gain in that year, while the equal and opposite loss on the put is deferred under the straddle rules for as long as the shares carry unrecognised gain. A collar that cost nothing in cash can therefore produce US tax in the year it ends.
Which forms carry it?
- Form 6781, Part II. Section A reports losses from straddles, with the unrecognised gain on offsetting positions that limits the deduction. Section B reports gains from straddles.
- Form 6781, Part III. A memorandum of unrecognised gains on positions held at the end of the tax year. For a low-basis shareholding this is the figure that supports the loss deferral.
- Form 8949 and Schedule D. Sales of shares on exercise, with the amount realised adjusted for premium, and any constructive sale.
- Schedule B and the qualified dividend line. Dividends reclassified as ordinary.
- Form 4952. Investment interest, after removing amounts capitalised under section 263(g).
The general rules are summarised in IRS Publication 550, which is the first reference an examiner will reach for.
How is a prepaid variable forward reported on the US return?
The starting point is Revenue Ruling 2003-7. On the facts of that ruling, a shareholder received an upfront cash payment, pledged the maximum number of shares that might be deliverable, and agreed to deliver a number of shares at maturity that varied significantly with the share price. The shareholder kept the right to deliver cash or other shares instead of the pledged shares, and was not economically compelled to deliver the pledged shares. The IRS concluded that there was no sale when the contract was signed, and no constructive sale under section 1259, because the contract was not one to deliver a substantially fixed amount of property.
The result is open-transaction treatment:
- Year of signing. No gain is reported. The cash received is not income. Nothing appears on Form 8949.
- During the term. The shares and the forward are a straddle. The holding-period, carrying-cost and qualified-dividend consequences described above apply.
- Settlement in shares. A sale is reported on Form 8949 for the year of delivery. The amount realised is built from the cash received at the outset, and the basis and holding period are those of the particular shares delivered.
- Settlement in cash. Gain or loss on the contract itself is reported, measured by the upfront payment against the cash paid to settle, with the straddle rules applying to any loss.
The share-lending caveat
The ruling depends on its facts. Where the pledged shares were also lent to the counterparty, or the counterparty was given the right to borrow, sell or rehypothecate them, the IRS has treated the arrangement as a completed sale at the outset. The Tax Court agreed in a 2010 decision that was upheld on appeal the following year, with gain recognised in the first year to the extent of the cash received. The preparer therefore needs the full documentation: the forward confirmation, the pledge agreement, and any share-lending or rehypothecation terms. A return that reports open-transaction treatment without those documents having been read is not properly supported.
Two further points. First, the IRS has said for many years that it is studying prepaid forward contracts, and no comprehensive guidance has followed, so the 2003 ruling remains the reference point. Secondly, later litigation has held that extending the term of an existing contract can be a taxable event in its own right. An amendment or roll of the contract should be treated as a reporting question for that year, not as a continuation to be ignored.
Form 8938 and the FBAR for a UK-held derivatives position
The information returns are where a missed hedge most often turns into a penalty exposure, because they are due whether or not any tax is owed.
- A custody, collateral or margin account with a UK institution is a foreign financial account. It is reported on the FBAR where the aggregate value of all foreign accounts exceeds $10,000 at any time in the year, and on Form 8938 above higher thresholds.
- An over-the-counter option or forward with a non-US counterparty that is not held in an account is itself a specified foreign financial asset for Form 8938. It is listed separately, with its maximum value in the year.
- Thresholds. For a taxpayer living abroad, Form 8938 is generally required where specified foreign financial assets exceed $200,000 on the last day of the year or $300,000 at any time, or $400,000 and $600,000 for a joint return.
- Pledged shares. Shares moved into a collateral account at the counterparty are still the shareholder's assets and still reportable. Moving them does not take them out of scope.
Shares in a US company held in a UK nominee account are a common blind spot. The shares are US securities, but the account is foreign. Our FBAR penalty calculator gives a sense of the statutory exposure for unfiled years, though penalties are rarely the outcome where a non-wilful failure is corrected through the proper procedure.
How does the UK treat the same collar?
The UK has no constructive sale rule, no straddle rules, no holding period and no concept of a qualified dividend. It taxes the options as assets.
Options are separate chargeable assets
HMRC's Capital Gains Manual at CG12310 confirms that an option is a chargeable asset and that the special rules sit in sections 144 to 148 of the Taxation of Chargeable Gains Act 1992. Applied to a collar:
- Call sold. The grant of an option is a disposal of the option. The premium received, less costs, is a chargeable gain on the date of grant, in the UK tax year in which that date falls.
- Call lapses. Nothing further. The gain on grant stands.
- Call exercised. The grant and the sale of the shares are treated as one transaction. The premium is added to the consideration for the shares and the separate gain on grant falls away.
- Put bought. The acquisition of an asset. No gain or loss arises on purchase.
- Put exercised. The purchase of the put and the sale of the shares are treated as one transaction. The cost of the put is deducted in computing the gain on the shares.
- Put lapses. The abandonment of an option is not a disposal under the general rule, so no loss arises. Traded options and financial options are excepted from that rule, and a put over shares written by a regulated financial institution will generally be a financial option, giving an allowable loss in the year of lapse. The classification should be confirmed against the contract.
Section 144ZA matters where the strike price differs from market value on exercise. It displaces the market value rule, so that the actual exercise price, adjusted for the premium, is used in the share computation. Cash-settled options are dealt with separately in section 144A, under which the settlement payment is treated as consideration for a disposal of the option.
The 30-day matching rule
Shares disposed of are matched first with acquisitions on the same day, then with acquisitions in the following 30 days, and only then with the section 104 pool at average cost, so a repurchase shortly after delivering shares under a hedge changes the UK gain.
Is a prepaid forward a UK disposal at the contract date?
This is the most important UK question and the answer turns on the terms. Section 28 provides that where an asset is disposed of under a contract, the time of disposal is the time the contract is made, not the later date of completion. If the contract is conditional, the time of disposal is when the condition is satisfied. HMRC's guidance is in the Capital Gains Manual at CG14261.
Three situations need to be distinguished.
- A fixed, physically settled forward. An unconditional contract to deliver a fixed number of shares at a fixed price is a disposal of those shares, and section 28 dates it to the day the contract was signed. The gain belongs to the UK tax year of signing, even though delivery is years away. The US, by contrast, would generally treat a fixed forward as a constructive sale in the same calendar year, so here the two countries broadly agree on timing, though not on the year end.
- A variable forward with a cash-settlement alternative. Section 28 fixes the time of a disposal; it does not create one. Where the shareholder may settle in cash and keep the shares, there may never be a disposal of the shares under the contract at all. If shares are eventually delivered, whether the disposal relates back to the signing date depends on whether the contract was, on its true construction, an unconditional contract for the sale of those shares. A contract under which the seller chooses what to deliver is difficult to describe in that way, and the more natural reading is often a disposal at settlement.
- A cash-settled contract. The contract itself may be an asset in its own right for capital gains purposes, with gain or loss arising when the obligations under it are closed out.
There is no HMRC manual page that works through a prepaid variable forward for an individual. The return should therefore record the analysis adopted and the contractual terms relied on, and the position should be disclosed clearly in the additional information space. Where a contract was signed on or after 6 April 2023 and completion falls well after the end of the tax year of signing, special rules also extend the time limits for assessment and for certain claims by reference to the completion date, which is relevant when a signing-date disposal comes to light late.
The upfront payment needs its own UK characterisation. If the contract is a disposal at signing, the payment is consideration. If it is not, the payment is closer to an advance, and no gain arises on its receipt.
Where the shares came from employment
For executives, and for founders who hold shares acquired as directors or employees, the employment-related securities rules in Part 7 of ITEPA 2003, the main UK employment income statute, sit on top of capital gains tax. The points a preparer checks are:
- whether the shares are still restricted securities, and whether an election was made on acquisition to be taxed on unrestricted market value;
- whether any amount received in connection with the shares, including under a hedge, could be a benefit within the post-acquisition charging provisions and so taxable as employment income instead of capital gain;
- whether a disposal under the contract is for more than market value; and
- whether the employer's annual employment-related securities return needs to reflect a reportable event.
Where part of a receipt is employment income in the UK, it is likely to be a different category of income for US foreign tax credit purposes as well, which affects the credit computation described below.
Dealing restrictions, as context
Senior executives and directors of listed companies are usually subject to dealing codes, closed periods and notification duties under market abuse rules in the UK and insider reporting rules in the US, and many employers prohibit hedging altogether. These are not tax rules and are outside the scope of a tax return engagement. They matter here only because public notifications create a dated record of the transaction that tax authorities can see.
Where the two returns disagree: the mismatch table
| Event | United States (Form 1040, year to 31 December) | United Kingdom (Self Assessment, year to 5 April) |
|---|---|---|
| Collar signed, not a constructive sale | No gain. Straddle begins: holding period, loss deferral, carrying costs and dividend character affected | Call premium is a chargeable gain on the grant date. Put is an acquisition |
| Collar signed, is a constructive sale | Shares treated as sold at market value on that date. Capital gain, long-term or short-term by holding period. Basis stepped up | No disposal of the shares. Call premium taxed as above |
| Call lapses | Premium is short-term capital gain on expiry date | No event. Gain remains in the year of grant |
| Put lapses | Capital loss on expiry date, deferred while shares carry unrecognised gain | Allowable loss in year of lapse if a traded or financial option; otherwise none |
| Call exercised | Sale of shares on exercise date. Premium added to amount realised | Sale of shares on exercise date. Premium added to consideration; earlier gain on grant withdrawn |
| Put exercised | Sale of shares on exercise date. Premium reduces amount realised | Sale of shares on exercise date. Put cost deducted |
| Prepaid variable forward signed | Open transaction if within Rev. Rul. 2003-7 and no share lending. Otherwise sale at signing | Disposal at signing only if an unconditional contract for sale of the shares. Otherwise no disposal yet |
| Forward settled in shares | Sale on delivery date. Amount realised based on upfront cash | Disposal at settlement, or related back to signing, depending on the contract |
| Dividends during hedge | Generally ordinary, not qualified | Dividend income at dividend rates. Hedge irrelevant |
| Interest on borrowing against the shares | Capitalised into basis under section 263(g) | Not deductible in computing the gain |
| Amount and currency | US dollars; lot-by-lot basis | Sterling at each transaction date; section 104 pool |
| Character | Capital; short-term or long-term; ordinary dividends | Capital, at 18% or 24%; possible employment income overlay |
What happens to the foreign tax credit when the two countries tax in different years?
A UK resident's gains on shares are taxed by the UK, and the US gives relief by foreign tax credit on Form 1116. That works smoothly only when both countries tax the same amount in overlapping periods. Hedged concentrated positions break that assumption in both directions.
US taxes first
If the collar is a constructive sale, or share lending turns the forward into a sale at signing, the US taxes the full gain in year one. The UK sees no disposal of the shares until they are actually delivered or sold, possibly several years later. When the UK charge finally arrives, the US basis has already been stepped up, so there is little or no US gain left in that later year for the UK tax to be credited against. Unused foreign tax credits can generally be carried back only one year and forward ten. A UK charge arising more than one US year after the constructive sale cannot reach back to it. The outcome can be tax in both countries on the same economic gain. Establishing whether that has happened, and whether any treaty-based position is available, is one of the first tasks in a catch-up engagement.
UK taxes first
If the UK treats a forward as a disposal at signing while the US holds the transaction open, UK tax is paid years before the US gain is reported. Here the ten-year carryforward usually bridges the gap, provided the credit is claimed and tracked on Form 1116 in each intervening year. The call premium on a collar raises a smaller version of the same point: taxed in the UK at grant, and in the US only at lapse.
Four technical points that decide the outcome
- Paid or accrued. An individual claims the credit when the foreign tax is paid unless an accrual election has been made. Under accrual, UK tax for a UK tax year generally accrues on 5 April. The choice changes which US year each UK payment falls into.
- Source. Gain on shares realised by a US citizen resident abroad is foreign source under domestic rules only if foreign tax of at least 10% is paid on it. A constructive sale with no UK tax at all fails that test, so the gain is US source and absorbs no foreign credit.
- Rate differential. Short-term gain on a lapsed call is taxed at up to 37% in the US and at no more than 24% in the UK. Long-term gain on the shares is taxed at up to 20% in the US. The credit limitation is computed by category, with adjustments for capital gain rate differences.
- Net Investment Income Tax. The IRS position is that the 3.8% tax is not reduced by foreign tax credits, so it can remain payable even where UK tax exceeds US tax overall.
Where UK tax is later amended, repaid or assessed for a year already used as a credit, the US return for the credit year must be corrected as a foreign tax redetermination. Catch-up work on the UK side therefore usually reopens the US side.
How do you catch up when the hedge was never reported?
The order of work matters more than the forms.
- Collect the documents. Option confirmations or the forward confirmation, the master agreement and schedule, the pledge or collateral agreement, any share-lending terms, account statements for every year, and dividend records.
- Classify the US position. Constructive sale or not; within the 2003 ruling or not; straddle start date; whether any identification was made.
- Rebuild the share attributes. Holding period, basis including capitalised carrying costs, deferred losses carried from year to year, and dividend character for each ex-dividend date.
- Classify the UK position. Gain on grant of the call by tax year; status of the put; whether and when any disposal of shares occurred; any employment income element.
- Allocate UK tax to US years and compute the credit, with carrybacks and carryforwards.
- Prepare the information returns: Form 8938 for each year and the FBARs.
- Choose the filing route.
US routes
Where returns were filed but the hedge was omitted, the correction is by amended return. Where the failure was non-wilful and involved unreported foreign financial assets, the IRS streamlined filing procedures generally require the three most recent years of returns and six years of FBARs with a signed certification of the facts. Taxpayers who meet the non-residency test under the Streamlined Foreign Offshore Procedures pay no miscellaneous offshore penalty. Where only FBARs were missed and all income was reported, the delinquent FBAR procedure may be sufficient.
Two limitation points make early correction worthwhile. The assessment period for a return generally does not begin to run in respect of items connected with an unfiled Form 8938 until the form is filed. And where more than $5,000 of income attributable to specified foreign financial assets is omitted, the ordinary three-year period becomes six.
UK routes
A Self Assessment return can be amended within 12 months of its filing deadline. For earlier years, tax underpaid is disclosed to HMRC voluntarily, and overpaid tax, for example where a gain on grant was correctly reported but should have been withdrawn on exercise, is reclaimed by overpayment relief within four years of the end of the tax year. HMRC's own assessment window is generally four years, six where there has been carelessness, and longer for offshore matters and deliberate behaviour. An unprompted disclosure attracts materially lower penalties than one made after HMRC opens an enquiry.
Common errors we see on returns for hedged shareholders
- Nothing reported at all, on the basis that no shares were sold.
- Dividends on collared shares entered as qualified.
- A loss on a lapsed put deducted in full in the year of lapse, ignoring deferral.
- Call premium reported in the US in the year of receipt, or in the UK in the year of lapse.
- Shares treated as long-term on delivery when the holding period had been eliminated.
- Margin or loan interest deducted when it should have been capitalised.
- Open-transaction treatment claimed for a forward without checking the share-lending terms.
- An extension or roll of the contract not considered as an event.
- The UK collateral account missing from the FBAR and Form 8938.
- UK tax credited in the wrong US year, or a carryback never claimed.
- No Form 6781 anywhere in the return history.
How Jungle Tax prepares these returns
Jungle Tax prepares US and UK returns for founders, executives and private investors as a single coordinated engagement. For a hedged concentrated position, that means one document set, two computations, and a reconciliation showing how each premium, each delivery of shares and each pound of UK tax has been treated on each return. Our US-UK tax accountants handle current-year filings and multi-year catch-up, alongside our US tax services, UK tax services and high net worth compliance work. We prepare and file returns. We do not advise on whether to hedge, on the terms of any derivative, or on investment matters, and the commercial and regulatory aspects of a transaction remain with your own advisers.
If you entered a collar or a prepaid forward over a large shareholding and are not certain that either return reflected it, the position can be rebuilt from the contracts and put right in the correct order. Please contact our cross-border team for a confidential consultation. We will review the documentation, identify what should have been reported in each country and each year, and set out precisely what needs to be filed.
