An American who moves to Britain and lets the old house back home often finds the rental runs at a loss once depreciation goes in. The instinct is to set that loss against salary.
Usually that does not work. Rental activities are passive by default, and a passive activity loss offsets passive income rather than earnings.
There is a carve-out worth real money, and it starts disappearing at an income level a lot of people reading this will already be past.
In our practice the suspended balance builds quietly for years, and nobody looks at it again until the house changes hands. That is actually the moment it matters.
So the question is not how to use the loss now. It is how to make sure it is still there, correctly tracked, when the sale finally happens.
What is a passive activity loss?
A passive activity loss comes from an activity the Code treats as passive, and it goes only against passive income rather than against wages or portfolio income. Publication 925 sets out the regime.
The restriction is on use, not on existence. The loss is real and it survives.
Why a rental is passive by default
Because the statute says so, which makes almost every rental shortfall a passive activity loss regardless of how involved the owner is. A rental activity counts as passive even where the owner materially participated in it.
That surprises people who manage the property themselves from four thousand miles away. Effort does not change the classification here.
The exception is for somebody who qualifies as a real estate professional, which is a demanding test built around hours and the nature of the taxpayer's work.
So assume passive unless somebody has tested the exception properly. Very few people reading this will meet it.
The test looks at the nature of the activity, not at the hours. That is what makes it so easy to get wrong from a distance.
The $25,000 allowance
Active participation, a lower bar than material participation, lets up to $25,000 of passive activity loss reach non-passive income. Approving tenants and approving expenditure can be enough.
The owner's interest, counting a spouse's, has to be at least 10% by value of all interests in the activity throughout the year.
That ownership condition rarely troubles somebody letting their own former home. The participation condition is the one to document.
So keep a record of the decisions you actually make. A managing agent does not stop you participating, but it makes the evidence thinner.
Where the allowance runs out
Half of every dollar of modified adjusted gross income above $100,000 cuts into it, so it falls away quickly once income rises.
By $150,000 of modified AGI it has gone completely. For a married filer that threshold arrives sooner than people expect.
A separate filer who lived apart from their spouse for the whole year has a reduced allowance of $12,500, with the phase-out running from $50,000 to $75,000.
Somebody filing separately while living with their spouse should check their own position rather than assume the reduced figure applies to them.
So run the figure before relying on it. The allowance is real, and for many people here it is already gone.
| Filing position | Allowance | Phases out between |
|---|---|---|
| Most filers, active participation | $25,000 | $100,000 and $150,000 of modified AGI |
| Separate filer, lived apart all year | $12,500 | $50,000 and $75,000 |
| Separate filer, lived with spouse | Check your own position | Do not assume the reduced figure |
| No active participation | None | Not applicable |
| Real estate professional | Outside the regime | Subject to meeting the test |
Why this bites Americans in Britain
Because married filing separately is the usual status for a US citizen with a non-American spouse, and the allowance treats separate filers differently.
Our note on filing separately with a British spouse covers why that status is so common here.
The income test also catches people whose British salary converts into a figure well past the phase-out, even on an ordinary professional income.
So two features of an entirely normal expatriate position combine to remove a relief most American landlords take for granted.
An illustrative example
Take an American in Manchester who kept a house in Denver and lets it. After mortgage interest, agent fees, insurance and depreciation the rental shows a loss of $9,000.
She files separately because her husband is British, and she lives with him. Her salary is comfortably into six figures once converted.
The $9,000 does not reduce her salary. The restriction suspends it, carries it forward, and leaves it waiting.
Six years later she sells the house. The whole accumulated balance comes through against the gain in that year, which is where the value finally appears.
What happens to the suspended balance
A passive activity loss carries forward without a time limit. Nothing expires, which is the saving grace of the whole regime.
Each year the suspended amount can go against passive income from the same or another passive activity. A second let property is the common case.
Otherwise it simply accumulates, and the schedule that tracks it becomes the most valuable document in the file.
So track it per activity and per year. A single running total falls apart the moment one property sells.
Keep the schedule with the tax papers rather than in a preparer's system. Preparers change and the balance has to outlive them.
The sale is where it unlocks
Disposing of the entire interest in a fully taxable transaction releases every loss still sitting unused, including the current year's.
Three conditions matter. The disposal has to cover the whole interest, it has to recognize all realized gain or loss, and the buyer must not be related to the seller.
A sale to a sibling therefore does not do it, and neither does a part disposal or an exchange that defers gain.
So plan the exit with the suspended balance in mind. The relief is substantial and it is easy to forfeit by accident.
Check the buyer is unrelated before exchange, not after. That one condition decides whether years of accumulated relief arrives or stays locked.
- Locate the suspended balance for the activity, year by year.
- Confirm the sale covers your entire interest in it.
- Confirm the transaction recognizes all realized gain or loss.
- Confirm the buyer is not related to you.
- Release the suspended losses against the gain in the year of disposal.
- Check the capital loss rules if what remains is a capital loss.
- Keep the final schedule, since the British return measures the same sale differently.
Does the UK side give relief in the meantime?
Britain has its own rules for property losses, and they take no notice of the passive activity loss regime. A loss on an overseas property generally carries forward against later profits of the same property business rather than against other income.
So both countries restrict the loss, but they restrict it differently and track it separately. Two schedules, two sets of figures.
Our note on a US rental as a UK resident covers the British computation.
So expect the two carried-forward balances to diverge. They are measuring different things under different rules.
Where the form fits
Form 8582 computes the restriction and carries the suspended amounts. It sits behind the rental schedule rather than replacing it.
The rental itself goes on the ordinary property schedule, and Schedule E carries the income and expenses.
The form is also the record. Somebody picking up the file years later reads the suspended balances from it.
So file it even in a year where the computation changes nothing. The continuity is the point.
Depreciation is what creates the loss
Most of these losses are not cash losses at all. The property may be comfortably cash positive and still show a loss once depreciation goes in.
Publication 527 sets the recovery period for residential rental property at 27.5 years under the general system, straight line with a mid-month convention.
That deduction is not optional in any useful sense, because basis falls by the depreciation you were allowed to claim whether or not you claimed it.
So the loss is largely an artifact of a deduction that comes back on the sale. Knowing that changes how people feel about it.
So nobody gains by skipping it. The deduction reduces basis either way, which is the worst of both outcomes for anybody who never claimed it.
Currency, and which figures the schedule uses
The American schedule runs in dollars throughout, which is straightforward where the property and the rent are American.
The British return needs the same transactions in sterling, on a method applied consistently across the year.
Our note on which exchange rate to use covers the choices and when each is defensible.
So keep one set of underlying records and two presentations of it. Rebuilding the second one later is the expensive version.
What to check on this year's return
Find the suspended balance. It should appear on the form, carried from last year.
Check it rose or fell for a reason you can name. A balance that jumped without a matching loss is a sign of a data entry problem.
Confirm the filing status on the return matches the one you actually used. The allowance turns on it.
So read the form rather than the summary. One line carries years of value.
Keep a copy outside the software. Exported returns are easier to read in five years than a login nobody renewed.
If a preparer changed partway through
Ask for the prior year carryforward schedules in full, not just the return. The balances live there.
Compare them against the earliest return you still hold. Gaps show up quickly.
Where a year is missing, rebuild it from the rental figures rather than guessing. The arithmetic is tedious but it is arithmetic.
So do this before a sale, not during one. A conveyance has its own timetable and will not wait.
Common mistakes we see
The first is setting a passive activity loss against salary because software allowed it. The restriction hides easily when somebody enters the rental without the right answers.
The second is assuming the $25,000 allowance applies. For a lot of expatriate filers, income or filing status takes it to nothing.
The third is losing the suspended schedule between preparers. The balance is worth real money and nobody reconstructs it easily.
A fourth is selling to a family member and expecting the losses to release. That disposal does not qualify.
How we help with a let US property
We start by rebuilding the suspended balances from the returns that exist, because that schedule is usually the thing that went missing.
Then we test the allowance against the actual filing status and income rather than assuming any passive activity loss can reach it.
Our US federal returns work covers the schedules and the carried-forward figures behind them, and you can get in touch well before a sale rather than during one.
So the planning window is the year before the disposal. After completion nothing moves.
