Accountants for US and UK: Selling a Trademark or Brand

When an American living in the UK sells a trademark or brand they own personally, HMRC usually treats the sale as a capital gain, while the IRS may treat some or all of the price as ordinary income. That happens when the seller keeps control rights, takes royalty-style payments or sells to their own company. Both returns must be prepared from the same deal papers and reconciled before either is filed.

Founders who need Accountants for US and UK compliance on a brand disposal are rarely dealing with an ordinary sale. The mark has often been owned outside the company for years, licensed informally to the founder's own trading business, and is then sold, either to that business or to an outside acquirer as part of an exit. This guide explains how Jungle Tax prepares the UK Self Assessment return and the US Form 1040 for that transaction, where the two systems diverge, and what has to be reported when the buyer is a UK company the founder controls. If the asset is a patent rather than a mark, read our companion guide on American inventors selling patent rights while UK resident. The rules for patents differ in important ways.

Why a personally held trademark is a cross-border problem

Most published guidance on selling intellectual property looks at one country only. US pages discuss section 1253 and capital gain versus royalty treatment but never mention HMRC. UK pages explain that a trademark is a chargeable asset for Capital Gains Tax and stop there. Neither covers the American founder resident in the UK, who is taxed on worldwide income in both countries in the same year and has to make the two results fit together through the foreign tax credit.

Three features make the brand sale harder than a share sale:

• Classification can differ. The same payment can be a capital receipt in the UK and ordinary income in the US. Sometimes the reverse happens, where HMRC sees disguised income and the IRS sees a clean sale.
• Timing can differ. The UK generally taxes the disposal when the contract is made, including a value for deferred or contingent consideration. The US often reports the gain as payments arrive, under the installment method or as royalties.
• Related-party rules bite on both sides. A sale to your own company brings in UK connected-party market value rules, the company's intangibles rules and US provisions that turn capital gain into ordinary income. It also triggers detailed US information reporting on Form 5471.

What exactly is being sold?

Preparation starts by pinning down the asset. A registered trademark, an unregistered brand, goodwill attached to a personal reputation, domain names, design rights and the right to receive existing licence income are different assets for tax purposes, even though founders often call them all "the brand". The sale agreement, the trademark registrations in each country and any existing licence to the operating company are the core documents.

Registration and situs

For UK Capital Gains Tax, a registered trademark is generally treated as situated where it is registered. A mark registered in more than one territory is treated as separate assets in each. This matters for an American who has only recently become UK resident, because the location of each registration can decide whether a gain is a foreign gain. We record each registration, its territory, its owner of record and its acquisition or creation date before any computation is done.

Sale, licence, or licence with an option

A full assignment of all rights is a disposal. A licence is not a disposal of the mark; it produces royalty income. A licence with an option to buy is two transactions: royalty income during the licence period, then a disposal if and when the option is exercised. Option premiums have their own treatment. Many founder arrangements are described as a "sale" but leave the founder with approval rights, a right to terminate or payments linked to turnover. That language decides the US result, as explained below.

How does HMRC tax the sale of a personally owned trademark?

Capital Gains Tax is the default

An individual who owns a trademark as an investment, outside any trade, normally makes a chargeable gain on disposal. The gain is the proceeds less allowable costs. For a self-created mark, those costs are often modest: registration fees, legal costs of registration and defence, and the incidental costs of sale. For disposals in the 2025/26 and 2026/27 tax years, the CGT rates for individuals are 18% within the basic-rate band and 24% above it, after the annual exempt amount of £3,000. Current rates are published on GOV.UK's Capital Gains Tax rates page.

Business Asset Disposal Relief rarely helps on its own

Founders often assume Business Asset Disposal Relief will apply. A standalone sale of a personally held trademark is not normally a disposal of a business or of shares. It may qualify only as an "associated disposal" alongside a qualifying disposal of the founder's shareholding, and the conditions are strict. Rent or royalties charged to the company for the period of use can restrict the relief. The BADR rate rose from 14% to 18% from 6 April 2026, so the relief is now worth much less against the 24% main rate. Where a claim is made, we document every condition in the return working papers.

When HMRC may treat the proceeds as income

The capital treatment is not automatic. The return has to be prepared with these income rules in mind:

• Trading. If the founder creates and sells brands as a business, the proceeds may be trading income rather than a gain.
• Royalties and licence income. Payments for the use of a mark, as opposed to its outright sale, are taxed as income from intellectual property in the year they arise. Payments calculated on sales during a continuing licence are royalties whatever the agreement calls them.
• Transfers of income streams. Selling the right to future licence income without selling the mark itself can be taxed as income under the UK's anti-avoidance rules on transfers of income streams.
• Sales of occupation income. Where the brand is essentially the founder's personal name and reputation, and the arrangement converts future earnings from personal activities into a capital sum, HMRC can treat that sum as income.

Deferred and contingent consideration

Brand sales often include an earn-out, typically a percentage of turnover for several years. In the UK, ascertainable deferred consideration is generally brought into the gain in the year of disposal with no discount, and the seller pays tax before the money arrives. Unascertainable contingent consideration is valued at the disposal date as a separate right, and later receipts are treated as disposals of that right. Where consideration is paid over more than 18 months, the tax can in some cases be paid by instalments. These rules can push UK tax into an earlier year than the US tax on the same money. That timing gap is one of the main reasons the two returns must be prepared together.

Selling the trademark to your own UK company

This is the most common founder scenario. It is also the one most often prepared badly.

Connected-party market value

An individual and a company they control are connected persons. A disposal between connected persons is treated as made at market value for CGT, whatever price was actually paid. If the agreed price is above or below a supportable valuation, the CGT computation uses market value, not the contract figure. The company's own position follows the corporate intangibles regime, which also substitutes market value for related-party acquisitions. Restrictions can apply where the mark existed before April 2002 or was acquired alongside goodwill. These rules are applied when the company's corporation tax return is prepared. The founder's return and the company's return should use the same independent valuation.

Overpayment and underpayment risks

Where the company pays more than market value, HMRC may treat the excess as a distribution or as remuneration, not sale proceeds. That can mean dividend tax or employment taxes in place of CGT. Where the company pays less, the founder is still taxed on market value and gets no extra cash to pay the tax. The UK transfer pricing rules can also adjust the company's deductions for amortisation or royalties to an arm's-length figure. Many smaller groups are exempt, so whether those rules apply to the company depends on its size. We confirm that point with the company's accountants before finalising the personal return.

How does the IRS tax the sale of a trademark?

As a US citizen or green card holder, the founder reports the transaction on Form 1040 wherever they live. The analysis runs in a fixed order.

Step 1: Is it a sale at all? Section 1253

Internal Revenue Code section 1253 says that a transfer of a trademark or trade name is not a sale or exchange of a capital asset if the transferor keeps any significant power, right or continuing interest. The statute lists examples. They include a right to disapprove any assignment, a right to terminate at will, a right to prescribe quality standards for goods or services, a right to require use of the transferor's own products or suppliers, and a right to payments contingent on productivity, use or disposition where those payments are a substantial element of the deal. Many founder-to-company transfers contain brand-guardian clauses that keep the founder in control of how the mark is used. Under section 1253 those clauses can make the whole consideration ordinary income.

Step 2: Contingent payments are ordinary regardless

Separately, amounts received on a transfer of a trademark that are contingent on its productivity, use or disposition are treated as received from the sale of a non-capital asset. A turnover-linked earn-out is therefore ordinary income in the US even if the fixed upfront price qualifies as capital gain. US case law also allows a single deal to be split, with some payments capital and others ordinary. We go through the agreement clause by clause and allocate each payment stream.

Step 3: Selling to a related company, section 1239

Where the US analysis would otherwise give capital or section 1231 gain, section 1239 can still convert it to ordinary income. It applies to a sale of property that is depreciable or amortisable in the buyer's hands to a related person, which includes an entity the seller controls more than 50% by value. A trademark is generally an amortisable section 197 intangible for the buyer. A founder selling a mark to their own UK company should therefore expect the IRS to see ordinary income, even when HMRC sees a capital gain. Related-party sales of depreciable property are also generally excluded from the installment method. The gain is then reported upfront, unless the IRS is satisfied that tax avoidance was not a principal purpose.

Step 4: Section 197 and recapture

Where the mark was bought rather than created, or was used in the founder's own trade, any amortisation already claimed is recaptured as ordinary income on sale. Any remaining gain on a business-use mark held for more than one year may be section 1231 gain. A mark held purely as an investment and not caught by sections 1253 or 1239 can produce long-term capital gain, taxed at the preferential federal rates of up to 20%. The 3.8% Net Investment Income Tax may also apply, and the IRS's position is that it cannot be reduced by foreign tax credits.

Step 5: Installment and contingent-payment reporting

For an outside buyer and a fixed or capped deferred price, the installment method on Form 6252 generally applies automatically unless the seller elects out on a timely filed return. Contingent-payment sales have their own basis-recovery rules. The election out of installment treatment is a filing decision with long-term consequences. Capital gains and losses are reported through Form 8949 and Schedule D.

US versus UK treatment at a glance

Issue	UK (HMRC)	US (IRS)
Default treatment of outright sale	Chargeable gain, CGT at 18% / 24%	Capital or s1231 gain, if no retained rights and no related-party rule applies
Founder keeps control or veto rights	Usually still a disposal; consideration remains capital	Section 1253 can make the entire price ordinary income
Turnover-linked earn-out	Valued at disposal as part of the gain, then later receipts taxed as disposals of that right	Ordinary income as received; sourced like a royalty
Sale to own company	Market value substituted; excess may be a distribution	Section 1239 ordinary income; installment method generally unavailable
Timing	Generally the contract date	Often as payments are received
Annual exemption / allowance	£3,000 annual exempt amount	None for gains; preferential rates only for long-term capital gain
Reporting	Self Assessment capital gains pages; deadline 31 January after tax year	Form 1040, Form 8949/Schedule D or Form 4797, Form 6252, Form 1116, and Form 5471 if buyer is a controlled foreign company

How do the two returns fit together? Treaty relief and the foreign tax credit

The US-UK income tax treaty gives the country of residence the main right to tax gains on intangibles. The saving clause preserves the US right to tax its citizens as if the treaty did not exist. In practice, the UK taxes first as the country of residence, and the US gives a foreign tax credit for UK tax on Form 1116. Three preparation points decide whether that credit actually works:

1. Sourcing. Under US sourcing rules, gain on personal property sold by a US citizen with a tax home abroad is treated as foreign source only if foreign income tax of at least 10% of the gain is actually paid. Where the UK charges nothing, for example because of a new-resident foreign income and gains claim, that rule fails. Contingent payments are sourced like royalties, by reference to where the mark is used. A mark used in the US can therefore produce US-source income on which a UK credit is restricted. In appropriate cases the treaty's re-sourcing provisions are needed to make the credit available.
2. Character and basket. Gains and royalties usually fall in the passive category for foreign tax credit purposes, unless they come from an active trade. If the US treats the receipt as ordinary income and the UK treats it as a gain, the credit is still available, because creditability turns on the foreign tax paid, not on how each country labels it. The basket assignment must still be correct.
3. Timing mismatches. If UK tax falls in the year of the contract and US income arrives over five years, credits may sit unused. Excess foreign tax credits can generally be carried back one year and forward ten. We model the carryforward schedule as part of the first-year return so that later years' returns pick it up correctly.

Currency is the final reconciliation item. The US computation is in dollars: proceeds are translated at the rate on the date of sale or receipt and basis at historical rates. Where proceeds are held in sterling, any later conversion can also produce a separate foreign currency gain or loss.

Form 5471 when the buyer is your own UK company

If the founder owns 10% or more of the UK company, they are generally required to file Form 5471 with their US return each year. If they control it, the company is a controlled foreign corporation. A sale of the trademark to that company has to be reflected in several places:

• Schedule M reports transactions between the company and its US shareholders, including sales and licences of intangible property and royalties paid.
• The company's income and earnings computations on the form use US principles. The company's amortisation of the purchased mark under US rules, which differs from UK accounting and tax amortisation, affects tested income for the US anti-deferral regime known as GILTI, renamed net CFC tested income for tax years beginning after 2025.
• Contribution rather than sale. If the mark was transferred for shares rather than cash, the transaction may be an outbound transfer of intangible property. Under section 367(d) that is treated as giving rise to deemed annual royalty income in the founder's hands, and it is reported on Form 926. This is very different from a sale and is a frequent error in self-prepared returns.

Penalties for a missing or incomplete Form 5471 start at $10,000 per form per year. They apply even when no US tax is due, and an incomplete form can keep the assessment period for the whole return open.

US-resident Americans with UK businesses

The reverse case is a US-resident American who owns the brand personally and sells it to their UK company or a UK buyer. The UK generally does not charge CGT on a non-resident's disposal of a trademark, unless the asset is used in a UK branch or the seller falls within the temporary non-residence rules. Those rules can tax gains on assets held at departure when someone who left the UK within the last five years returns. The US return then carries the full analysis above with no UK credit, and state income tax may also apply. Royalties paid by the UK company to a US-resident individual are generally relieved from UK withholding under the treaty. The UK company still needs to record the payment correctly, and Form 5471 obligations are unchanged.

Worked example: founder sells a UK and US-registered brand to their own company

The following simplified illustration shows how we prepare both returns. It is illustrative only and is not advice on any particular transaction.

• A US citizen, UK resident for many years, owns marks registered in the UK and the US. They were created personally a decade ago, with total registration and legal costs of £20,000.
• In 2026/27 the founder sells both marks to their wholly owned UK trading company. The price is £1.5 million upfront plus 2% of brand turnover for four years. The founder keeps a right to approve any onward assignment.

UK return: an independent valuation supports £1.5 million plus a disposal-date value for the earn-out right. CGT is calculated on market value less £20,000 costs and the £3,000 annual exempt amount, largely at 24%. Later earn-out receipts are compared with the value already taxed, and the difference is reported as a further gain or loss in each later year.

US return: the assignment-approval right is a significant retained right under section 1253, and the sale is to a more-than-50%-owned entity, so section 1239 applies as well. The upfront price is ordinary income in the year of sale, and the earn-out is ordinary income as received. UK tax on the gain is claimed as a foreign tax credit, with sourcing tested separately for the US-registered mark. The company's purchase and the earn-out payments appear on Schedule M of Form 5471, and the company's US-basis amortisation flows into its tested income.

The result is ordinary income at up to 37% in the US against capital gain at 24% in the UK, partly offset by credits. Every figure on the two returns traces back to one valuation and one agreement.

Behind on filings? Catching up before or after the sale

A brand sale often shows that earlier years were never filed correctly. Licence payments from the company may never have been reported, Forms 5471 may never have been filed, or the UK accounts that received the proceeds may be missing from FBAR and Form 8938 reporting. Where the failure was non-wilful, the IRS Streamlined Foreign Offshore Procedures let a US citizen living abroad file three years of amended or late returns and six years of FBARs, generally without failure-to-file penalties. Missing information returns can usually be brought in through the same submission or the separate delinquent international information return route. Our IRS streamlined filing team regularly prepares these submissions alongside a current-year disposal, so that the history is corrected before the sale year is filed. You can estimate your exposure with our FBAR penalty calculator.

Documents we need to prepare both returns

• The signed assignment, licence or option agreement, plus any side letters and brand-guardian or quality-control schedules
• Trademark registration certificates for every territory, with dates and owner of record
• Evidence of acquisition or creation costs, and any amortisation previously claimed
• The independent valuation, especially for any connected-party sale
• Payment records showing amounts, dates and currency for each instalment or earn-out receipt
• Prior-year licence income records, UK returns and US returns, including any Forms 5471 already filed
• The company's statutory accounts and corporation tax computation for the year of purchase

Why specialist cross-border preparation matters

A brand sale is one transaction reported on at least two personal returns, and often a corporation tax return and a Form 5471 as well. A UK-only accountant may file a clean CGT computation that leaves the US return exposed under section 1253 or 1239. A US-only preparer may miss the UK market value rule or the income-stream anti-avoidance provisions. Our US-UK tax accountants prepare both sides together from one set of papers, and our high-net-worth practice regularly handles founder exits that combine IP disposals with share sales.
