Nonresident State Tax Return for Rental Property Abroad

Moving to London does not end a US state filing obligation on a rental property you left behind. States tax income by source as well as by residence, so rent from a property physically located in a taxing state is generally taxable there whatever your residence — and a nonresident state return is usually due every year.

That is the single most common gap we find in an otherwise complete federal catch-up. If you moved from the United States to London and kept a rental property behind, a nonresident state tax return for rental property is almost certainly still due in the state where that property sits — every year, for as long as you own it and for the year you sell it. At Jungle Tax we see this pattern repeatedly: three or five years of federal returns and FBARs brought current through the IRS procedures, a clean 1040 package, and behind it a state file that has been silent since the year of departure.

Why did leaving the state not end the filing obligation?

US state income tax rests on two independent hooks, and most people who move abroad only think about one of them.

The first is residence. A state taxes its residents on worldwide income. Breaking residence — genuinely, evidentially, and usually with a part-year return in the year of departure — switches this hook off. That is the exit exercise we cover in our guide to state tax residency exit from California and New York, and in the aggressive states it is a real project rather than a formality.

The second hook is source. A state also taxes non-residents on income sourced within its borders. Income from real property is sourced, in essentially every state income tax system, to the physical location of the land. The building does not move when you do. Rent it produces is state-source income in the hands of a Miami resident, a Manhattan resident, or a resident of Kensington, and residence is simply not part of that test.

So the successful residency exit that the London mover is quietly relying on solved the wrong problem. It ended taxation of worldwide income by the old home state. It did nothing at all to the state's claim on the rent from the house on the other side of town. Those are two different taxing rules, and switching one off leaves the other running.

Does it matter that the tenant pays into a UK account, or that a manager collects the rent?

No. Where the money is banked, who collects it, whether it is remitted to the UK or left in a US account, and whether the landlord ever sets foot in the state again are all irrelevant to source. The sourcing rule looks at the location of the asset producing the income. A US property management company collecting rent and wiring the net to a London bank account produces exactly the same state-source income as a landlord walking round to collect a cheque.

Are there states where nothing is due?

Yes, and this is worth checking before you assume the worst. States that impose no broad personal income tax do not levy income tax on rental profit either, so a property in one of them generates no annual state income tax return. Several other states impose filing thresholds low enough that any meaningful rental profit clears them, and a handful require a return even where the net result is a loss. The rule is state-specific: the correct first step is to identify the state, then the threshold, then the form — not to generalise.

Which filings does the London-based owner actually owe each year?

Three separate returns, in three separate systems, on the same underlying rent. A high-net-worth landlord who thinks of this as "my US tax return" is usually already one filing short.

Return	Who requires it	What it reports	Typical mechanics
Federal Form 1040, Schedule E	IRS	Worldwide income, including the US rental profit or loss	Depreciation, passive activity loss limits, possible net investment income tax
Nonresident state income tax return	The state where the property sits	State-source income only — here, the rental result	Often begins with the federal figures, then applies state modifications
UK Self Assessment, SA100 plus SA106 foreign pages	HMRC	The same rent, recomputed under UK property income rules	Credit relief for US tax, subject to the UK tax on that income

The federal position is the well-trodden one. Rental income and expenses go on Schedule E of Form 1040. The foreign earned income exclusion does not reach it, because rent is not earned income. Depreciation on the building is mandatory in substance — you either claim it or you are treated as having claimed it when you sell — which is why an improperly depreciated property is so often the second problem we find alongside the missing state returns. We deal with that repair in our guide to rental depreciation and Form 3115.

How does the nonresident state return interact with the federal return?

Almost every state builds its return on the federal one. The nonresident return typically starts from federal adjusted gross income or from federal taxable income, then applies state-specific modifications, then applies an apportionment or allocation step that isolates the state-source portion. In practice that means:

• The federal return has to be right first. A state return prepared from a federal return you intend to amend is a state return you will have to amend too. Sequence the work.
• The state figure is frequently not the federal figure. States decouple from federal rules in ways that bite rental owners specifically: different depreciation conventions, different treatment of bonus depreciation, their own passive activity loss tracking, their own basis records. Two numbers that should be identical routinely are not, and the difference has to be documented rather than ignored.
• State returns generally ignore your expatriate reliefs. States do not adopt the foreign earned income exclusion, and most do not give a credit for foreign tax paid to the UK on non-state-source income. There is no state-level equivalent of the federal foreign tax credit machinery for a UK resident. Whatever relief exists has to come from the UK side.
• The state tax you pay is a federal deduction in principle — state income tax is an itemised deduction, subject to the federal cap on state and local tax deductions — which is a small offset, not a solution, and often worth nothing to a filer taking the standard deduction.

If the property runs at a loss, is a return still worth filing?

Usually yes, and this is the point most generalist guidance skips. Depreciation frequently turns a cash-positive rental into a taxable loss. Three reasons to file anyway:

• To preserve state loss carryforwards. States that track their own suspended passive losses will generally only recognise losses that were reported on a filed return. Unfiled loss years can mean losses you cannot use against the gain when you eventually sell.
• To start the state limitation period. In most systems the assessment clock does not start until a return is filed. Unfiled years stay open indefinitely. A landlord who has not filed since 2015 has an open exposure back to 2015, not a three-year one — and that asymmetry is the reason state exposure so often exceeds the federal exposure it sits behind.
• To keep the file consistent. A state that later matches Form 1099 data, a property manager's reporting, or a real property transfer record against a nil filing history is a state that opens an enquiry. A run of filed loss returns is a very different starting position.

Why does the US–UK treaty give you nothing at state level?

This is the structural point, and it is where cross-border advice usually stops short. The US–UK double taxation convention allocates taxing rights between two sovereign states. Its "taxes covered" article, on the US side, reaches the federal income taxes imposed under the Internal Revenue Code and certain federal excise taxes. Taxes levied by the individual states are outside it.

Two consequences follow, and they run in opposite directions.

First, the treaty does not restrain the state. Nothing in it prevents a state from taxing the rental income of a UK-resident owner. On income from immovable property the treaty in any event permits the country where the property is located to tax it, so even at federal level the US keeps the primary claim; at state level the treaty is simply not in the conversation.

Second — and this is the part that saves money — the treaty's relief article does not cover state tax either, so the UK credit for state tax has to be found elsewhere. It generally is. HMRC's International Manual records that the agreement with the United States covers federal income taxes and certain federal excise taxes but not taxes levied by individual states, and that unilateral relief is available for many of those state taxes. Unilateral relief is the domestic UK mechanism that gives credit for foreign tax on foreign-source income where no treaty relief applies, provided the foreign tax corresponds to UK income tax or capital gains tax. State income tax on rental profit normally does.

The practical translation: a UK-resident American with a US rental should be claiming credit for federal tax under the treaty and for state income tax under unilateral relief, on the same foreign pages, as two separate lines of reasoning. A UK return that claims only the federal tax has overpaid HMRC. A UK return that lumps them together without distinguishing the basis of the claim is harder to defend if HMRC asks — and HMRC has been writing to taxpayers about foreign tax credit relief claims.

The UK side: the same rent, taxed again, under different rules

A UK resident is taxable on worldwide income, including overseas property profits, which are reported on the SA106 foreign pages of the Self Assessment return. For those on the remittance basis in earlier years, or claiming under the newer regime for recent arrivals, the analysis differs and needs separate handling. For the settled London-based American — typically several years in, well beyond any arrival-year relief — the rent is UK-taxable in full as it arises.

The double-count risk is not that the income is reported twice. It is that the two systems compute a different profit from identical facts, and credit relief only works cleanly when the numbers line up. They rarely do.

Item	US federal / state treatment	UK treatment	Where the mismatch bites
Building depreciation	Mandatory straight-line depreciation of the building over a statutory recovery period	No depreciation allowance on the building	UK profit is systematically higher than the US profit on the same rent
Mortgage interest	Deductible in computing rental profit	Relief for residential finance costs restricted to a basic-rate tax reducer	A geared property can show a US loss and a UK taxable profit
Furnishings and appliances	Capitalised and depreciated	Relief on replacement of domestic items, not on the initial purchase	Timing differences that never reconcile year on year
Accounting basis	Generally accruals, with elections available	Cash basis by default for smaller property businesses, with an accruals election	Rent received in a different period in each system
Tax year	Calendar year	6 April to 5 April	Credit relief has to be apportioned across two US years
State income tax	Imposed by the property's state; no treaty protection	Creditable, but by unilateral relief rather than under the treaty	Missed entirely on UK returns prepared by US-only advisers, and vice versa

Why does a US loss plus a UK profit produce real double taxation?

Take the archetype. A London-based American owns a leveraged US rental. Depreciation and full mortgage interest deductions produce a modest federal and state loss. Under UK rules there is no depreciation and the interest is not deductible against the rent — it produces a basic-rate reducer instead — so the same property shows a UK taxable profit, taxed at the owner's marginal rate.

The owner now has UK tax to pay on a property that generated no US tax, and therefore no US tax to credit against it. Credit relief is capped at the lower of the foreign tax paid and the UK tax on the same income; if the foreign tax is nil, the relief is nil. Meanwhile, in a later year when the US position turns profitable — say the mortgage is repaid or depreciation runs out — there may be US and state tax with insufficient UK tax that year to absorb it. Unrelieved foreign tax on property income cannot simply be carried around between years the way federal foreign tax credits can be carried in the US system.

This is a computation problem, not a filing problem, and it is solved by preparing both returns together rather than sequentially by two firms who never speak. That co-ordination is the core of what our cross-border tax service does for property-owning clients.

Does holding the property through a US LLC help?

It usually complicates rather than helps. A single-member LLC is disregarded for US federal purposes, so the rent flows straight onto the member's Schedule E and the state return, exactly as if held personally. HMRC's long-standing position, however, is generally to treat a US LLC as an opaque entity — a company rather than a transparent partnership — notwithstanding the Supreme Court's decision in the well-known 2015 case that turned on the specific terms of the LLC agreement. Where HMRC treats the LLC as opaque and the US treats it as disregarded, the two systems can be taxing different persons on different receipts at different times, which is precisely the situation in which credit relief fails. If a UK-resident American holds US property through an LLC, the entity classification question should be resolved before the returns are prepared, not after.

Why do the state returns go missing in a federal catch-up?

Because the federal relief programme does not mention them. The IRS streamlined filing compliance procedures are a federal programme: three years of federal returns, six years of FBARs, a non-willfulness certification, and federal penalty relief. States are not parties to it, are not bound by it, and are not notified by it. A taxpayer who has completed a textbook streamlined submission has satisfied the IRS and has done nothing whatsoever about the state.

The result is a very specific and very common shape of problem: a client who is confident they are "fully caught up", holding a professionally prepared federal package, with an open-ended state exposure sitting underneath it that nobody in the chain owned. We wrote about the general version of this gap in the state returns gap in streamlined filing; the rental property version is the sharpest form of it, because unlike wage income there is a permanent, publicly recorded, physically located asset generating the income year after year.

There is a second mechanism worth understanding. States increasingly receive data. Property transfer records, county assessor data, information returns issued by property managers and payment platforms, and federal data-sharing agreements all give a state ways to observe that a person owns income-producing real property within its borders and has filed nothing. Detection is not a coin flip on a long enough horizon.

How do you fix several missing years?

The sequence matters more than the speed. In outline:

• Scope the state, not the country. Confirm the state's filing threshold, its nonresident return form, its treatment of losses, and whether it has a formal voluntary disclosure programme for non-filers. These vary substantially, and the answer determines the route.
• Rebuild the depreciation schedule from acquisition. Missing years cannot be prepared correctly without a defensible basis, placed-in-service date, land-and-building split, and improvement history. This is usually the longest part of the work and is worth doing once, properly.
• Fix the federal years first. Amend or file the federal returns so the state returns are built on final numbers.
• Assess the voluntary disclosure route. Many states operate voluntary disclosure agreements that limit the look-back period — often to a fixed number of years rather than the open-ended exposure that unfiled years otherwise carry — and waive some penalties, in exchange for coming forward before contact. Eligibility is normally lost once the state has written to you. Where a client has several missing years, this is frequently the difference between a bounded and an unbounded outcome.
• Reconcile the UK returns in parallel. If the US and state numbers move, the credit relief claimed on the UK returns for those years moves too. Where UK returns were filed without claiming state tax relief, amendment windows should be checked immediately — the right to amend is time-limited, and the overpayment is real money.
• Document the position. A file that explains, contemporaneously, why the state figure differs from the federal figure and how the UK credit was computed is what turns a future enquiry into a short correspondence rather than a long one.

What happens when you sell?

The state's claim does not end with the rent. Gain on the disposal of real property is state-source income in the state where the property sits, so a nonresident return is due for the year of sale even if the property produced losses throughout. Two features regularly surprise London-based sellers:

• Withholding at closing. Several states require the closing agent to withhold estimated state tax from a nonresident seller's proceeds and remit it, with the seller recovering any excess only by filing the nonresident return. A seller who does not file leaves the withheld money with the state permanently.
• Depreciation recapture. The federal gain includes recapture of depreciation allowed or allowable, and the state generally follows with its own version, computed on its own basis figures. A landlord who never claimed depreciation is still taxed as though they had — the reason the depreciation repair matters long before a sale is contemplated.

On the UK side the same disposal is a chargeable gain for a UK resident, computed under UK rules in sterling — which introduces a currency element the US computation does not have, since the US measures the gain in dollars throughout. A property that produced a modest dollar gain can produce a substantial sterling gain, or the reverse. Credit relief for the US and state tax on the gain follows the same two-track logic as the rent: treaty relief for federal tax, unilateral relief for state tax.

The mistakes we see most often

• Assuming the residency exit closed the file. It closed the residence hook, not the source hook.
• Treating "no tax due" as "no return due". Filing thresholds are usually stated by reference to gross income or state-source income, not tax liability.
• Claiming only federal tax as credit on the UK return. State income tax is generally creditable by unilateral relief and is routinely omitted.
• Preparing the UK return from the US numbers. The UK profit must be recomputed under UK rules; copying the Schedule E figure is wrong in both directions.
• Leaving depreciation unclaimed to keep the return simple. It is recaptured on sale regardless, so the deduction is lost and the tax is not.
• Filing state returns quietly for the current year only. Filing forward without addressing prior years can forfeit voluntary disclosure eligibility while flagging the earlier gap.

Getting the whole position straight

The clients this affects are rarely careless. They are typically senior executives, founders and investors who took competent US advice on leaving, competent UK advice on arriving, and discovered that the seam between the two is exactly where a nonresident state return lives. Our work for high-net-worth cross-border clients is built around that seam: one team preparing the federal, state and UK returns as a single computation, so that the same rent is reported correctly three times and taxed properly once. Where the federal position also needs bringing current, we run that through the streamlined filing procedures at the same time, and where the UK returns need correcting, our UK compliance team handles the amendments alongside.

If you moved to London and kept a US rental property, the question is not whether a state return is due — it usually is — but how many years are open, which route closes them on the best terms, and how much UK tax you have overpaid by omitting the state credit. That review is confidential, it is quick to scope, and it is far better done before a state letter arrives than after.
