What does the default actually cost?
US rental income paid to a foreign owner is treated as what the tax code calls FDAP income. The rule is simple and unforgiving: 30% of the gross, withheld at source, with no deductions permitted. There is a fuller account of how the US taxes foreign owners at every stage in my US tax guide for foreign investors.
Take a property renting at $1,200 a month with a $700 mortgage payment, $150 of taxes, $80 of insurance and $120 of management.
The default, on a property renting at $1,200 a month | Monthly | Annual |
|---|
| Rent collected | $1,200 | $14,400 |
| Actual costs | $1,050 | $12,600 |
| Actual profit | $150 | $1,800 |
| Tax at 30% of gross | $360 | $4,320 |
You made $1,800 and the tax bill is $4,320. You are paying tax at more than twice your profit, and you are cash flow negative on a property that was cash flow positive.
But that is the default. It applies automatically, without anybody doing anything wrong, until you change it proactively.
As an aside, the $150 of property tax in that table is a separate annual bill, and the listing figure for it is usually wrong, as I have set out in how US property tax works.
Once you have made the election on your US tax return, the same property is taxed on the $1,800, after depreciation, at ordinary graduated rates. In practice that often produces a very small bill or none at all. In this case, deducting depreciation would create a loss on paper, so no tax due, and a carryover of losses into the next year.
That is the magic of US real estate. When you know how the rules work, it is the most tax efficient asset to own. You can put your own numbers through the US rental income tax calculator to see both figures side by side.
Step one: why do I need an ITIN before anything else?
An ITIN is a US tax number for people who need to deal with the IRS but cannot get a Social Security number. You apply on Form W-7.
Do this first, and do it before you let the property.
Everything else needs it. You cannot file a US tax return without one. The W-8ECI has a line demanding a US taxpayer identification number and marks it required. You can use your EIN as a placeholder if you own the property through an LLC or LP. But you will still need an ITIN to file your own tax return. Your property manager cannot process a form that has an empty box where the number should be.
The delay people run into is not the ITIN itself. It is applying for one in February, at the same time as trying to sort out withholding and prepare a return, when the sensible time was before the first tenant moved in. If you are buying turnkey, settle it before you commit.
If you already have an ITIN from a previous property, you do not need another. It carries across.
This is the form that actually stops the money being withheld.
Form W-8ECI certifies that your rental income is effectively connected with a US trade or business (ECI), which means your property manager no longer has to withhold. It is titled, in full, a foreign person's certificate that income is effectively connected with the conduct of a trade or business in the United States.
Give it to your property manager. Do not send it to the IRS. The instructions say so explicitly. It is a document for your withholding agent, not a filing.
It is valid for three years, and expires at the end of the third calendar year after signing. Diary it. An expired form means your manager treats you as undocumented and the withholding starts again at 30%.
I cover what to do if your property manager asks for the wrong form below.
And it works going forward only. Rent collected before your manager has the form has already had 30% taken. That money is not lost, but you get it back later, through your return, not through the form. Just avoid that altogether by providing the form along with your signed property management agreement.
Step three: what is the section 871(d) election?
Here is the part that catches nearly everybody. The W-8ECI and the section 871(d) election are two different things, and doing one does not do the other.
- The W-8ECI goes to your property manager. It stops the withholding.
- The section 871(d) election goes to the IRS, as a statement attached to your Form 1040-NR. It is what actually changes how you are taxed.
You need both. A W-8ECI without the election is a certification you have not backed up. An election without the W-8ECI means you are taxed correctly but still having 30% taken every month and claiming it back a year later.
The election is made by attaching a statement to your return for the year it applies. The IRS sets out what it must contain on its own page for nonresident aliens with US real property.
And once made, it stands. The election stays in effect for every later year unless you revoke it, and revoking it needs IRS approval except in narrow circumstances. You make it once.
The one thing to remember: the form stops the withholding, the election changes the tax. They are separate, they go to different places, and you need both.
Where do the deductions actually go on the return?
This is the part nobody explains, and it is worth knowing before you hand a shoebox to a CPA.
Rental income and expenses go on Schedule E, Part I, which attaches to your Form 1040-NR. The IRS says so on the form itself: Schedule E is headed "Attach to Form 1040, 1040-SR, 1040-NR, or 1041." The same schedule an American landlord uses.
Each property gets its own column. Rents received go at the top, the fifteen expense categories sit on lines 5 to 19, and the net figure carries through to your return.
Schedule E, Part I: where each rental figure goes| Line | What goes on it | The catch |
|---|
| 3 | Rents received | Late fees, application fees and retained deposits count as income too |
| 5 | Advertising | Listing costs, photography, signage |
| 6 | Auto and travel | Rarely relevant to an overseas owner |
| 7 | Cleaning and maintenance | Routine upkeep. Not repairs, which are line 14 |
| 8 | Commissions | Leasing fees paid to place a tenant |
| 9 | Insurance | The actual premium, not your monthly escrow payment |
| 10 | Legal and professional fees | Including CPA fees for preparing the rental schedules |
| 11 | Management fees | The monthly percentage |
| 12 | Mortgage interest | Interest only. Principal is not an expense. |
| 13 | Other interest | |
| 14 | Repairs | Fixing what is broken. Improvements get depreciated instead |
| 15 | Supplies | |
| 16 | Taxes | Property tax. The actual bill, not the escrow |
| 17 | Utilities | Where you pay them rather than the tenant |
| 18 | Depreciation | Usually the largest single line, and the reason the bill is small |
| 19 | Other | HOA dues go here, described |
| 20 | Total expenses | Lines 5 to 19 added up |
Three of those catch people out repeatedly.
Line 12 takes interest only. Your mortgage payment is mostly principal in later years and principal is not deductible. It builds your equity instead.
Lines 9 and 16 take the actual amounts, not the escrow. Your lender collects an estimate monthly. What you deduct is what the insurer and the county were actually paid.
And line 14 against line 18 is the distinction that matters most. Fixing a leak is a repair and comes off this year. Replacing the roof is capital, goes into your basis, and is written off over 27.5 years. Getting that line wrong in either direction costs money, and I have set out where it falls in maintenance, repairs and capital.
The depreciation line is doing most of the work. On a $150,000 house with a $120,000 building that is $4,364 a year, claimed whether or not you spent anything. It is what usually turns a modest profit into a nil tax bill, and it is worth claiming even where it appears to save you nothing, for reasons in the depreciation advice that costs foreign investors thousands.
Step four: do I have to file every year?
Making the election commits you to filing Form 1040-NR every year, whether or not you owe anything.
The deadline for a nonresident with no US wages is 15 June, not April, though filing earlier does no harm. Your own country wants a return as well, and for Canadians the two systems interact in specific ways, set out in the US tax guide for Canadian investors, and for British owners in UK tax on US rental income.
Most foreign owners with a mortgage find their taxable income is small or nil once depreciation is applied, and depreciation is worth claiming even where it appears to save you nothing, for reasons I have set out in the depreciation advice that costs foreign investors thousands. File anyway. The election depends on it, and a year of not filing is how people end up back on 30% gross with a mess to unpick.
This is the practical obstruction, and it has happened to me more than once.
A manager who has not worked with foreign owners before will ask for a W-9. It is one of several things worth checking before you appoint one, as I have set out in when your property manager is the biggest risk. Some ask for a W-8BEN. Very few know what a W-8ECI is.
They are not being difficult. A property manager acting as a withholding agent is personally liable for tax they should have withheld and did not, plus interest and penalties. Without a valid form on file they must withhold the full 30%. Their caution is rational and it is your problem to solve, not theirs. If you are still deciding whether to use a manager at all, both sides are in should you self-manage a US rental from abroad.
Here is what each form is actually for.
Which form is which| Form | Who it is for | What it does |
|---|
| W-9 | US persons | Certifies you are American. Not you. |
| W-8BEN | Foreign persons accepting the default | Certifies foreign status, keeps the 30% |
| W-8ECI | Foreign persons who have made the election | Certifies the income is effectively connected, stops the withholding |
The LLC trap, which even accountants get wrong
I had a property manager in Cleveland whose accountant insisted, firmly, that I should be filing a W-9 or a W-8BEN, because the property was held in a US LLC. Cleveland is still a market we buy in, and my client Daniel owns there, which is written up in his case study.
The reasoning sounds right. It is a US company. US companies file W-9s. It took my own CPA explaining it to them before the matter was settled.
They were wrong, and Form W-9 says so on the form itself. In a caution box, in the instructions: a disregarded US entity that has a foreign owner must use the appropriate Form W-8.
The logic runs the opposite way to the intuition. A single member LLC with a foreign owner is disregarded for US tax. The IRS looks straight through it to you. Where the LLC was formed is irrelevant. What matters is who owns it. But disregarded does not mean invisible. That same LLC carries an annual filing with a $25,000 penalty behind it, set out in the form nobody mentions when they tell you to form an LLC.
And the W-8ECI has anticipated exactly this. Line 1 is your name. Line 3 is "Name of disregarded entity receiving the payments." The IRS has provided a box for the LLC, which is fairly conclusive proof that this is the right form for an LLC-held rental.
Where you get pushback, send them three things: the caution note in the Form W-9 instructions, line 3 of the W-8ECI, and the W-8ECI instruction that says the form is given to the withholding agent rather than the IRS. That combination has settled it every time for me.
And it is worth saying what this tells you. A qualified accountant got this wrong with complete confidence. So the question to ask a property manager, or an accountant, is not whether they know what they are doing. It is whether they have done it for a foreign owner before. It belongs on a short list to settle before you appoint anybody, alongside the failures in when your property manager is the biggest risk.
Why does the W-8ECI look like the wrong form?
Four things on the W-8ECI make foreign owners think they have been handed the wrong document. Each one has a straightforward answer.
"Business address in the United States." You do not have an office in America, you have a rental house. Your LLC mailing address is what goes here.
"U.S. taxpayer identification number (required)." A form for foreign people demanding an American tax number does look odd. It is why the ITIN is step one rather than step three. But again, if you own through a US legal entity such as an LLC or LP, use the EIN for the entity.
"Trade or business in the United States." Most foreign landlords own one house and do not consider themselves to be running an American business. The election is what makes it a trade or business for these purposes. That is the whole mechanism, and it is buried in the instructions rather than stated on the face of the form.
And the certification. Part II ends by certifying, under penalties of perjury, that the amounts are effectively connected, that the income is includible in your gross income, and that the beneficial owner is not a U.S. person.
That last line confirms you are foreign. It is the one part of the form that is unambiguously reassuring, and it sits at the bottom where nobody reads it.
What if 30% is already being taken from my rent?
Very common, and it is fixable.
Money already taken is claimed back on your Form 1040-NR for that year. Your manager reports the withholding, you report the income and the deductions, and the difference comes back as a refund.
And the election is not limited to your first year. It can be made on an original return, and in many cases on an amended return or retroactively with a reasonable cause explanation. Being two years late is not fatal.
Then get the W-8ECI to your manager immediately, because every month without it is another 30% you will be waiting a year to reclaim.
The same pattern shows up on the way out, incidentally. Selling triggers a separate withholding regime with its own paperwork and its own delays, which I have set out in how to get your FIRPTA money back. The tax that withholding is held against is a different number again, built from basis and depreciation on a real sale in capital gains tax when a foreign owner sells.
What would I do, in order?
Get the ITIN before the first tenant moves in. Not at tax time. The entity behind it has an annual filing of its own with a $25,000 penalty, set out in the $25,000 form nobody mentions.
Ask any prospective property manager whether they have handled a foreign owner before, and specifically whether they know what a W-8ECI is. What else to ask, and what their fee list tells you, is in what US property management actually costs. Their answer tells you a great deal. Working only with managers who already do this is one of the reasons our remote management service exists.
Send the W-8ECI on day one, with the LLC on line 3 if you hold it that way. Whether an LLC is the right wrapper at all is a separate question. For Canadians it is not the obvious one, as I have set out in LP vs LLC for Canadians.
Have your CPA make the election on your first return, and check they have actually attached the statement. Ask about your estate position while you have their attention, because a US LLC does far less for that than most owners assume, as I have set out in US estate tax for foreign property owners.
Diary the three year expiry on the W-8ECI, the same way you would diary any other recurring cost on the property, which are set out in maintenance, repairs and capital.
And file every year, even when there is nothing to pay. What the same property costs you on the way out is in capital gains tax when a foreign owner sells.
You can also test the difference on a specific deal with the rental property cash flow calculator. If you want to size the difference on your own property before you start, the free tools in my investor starter kit cover the deal, the cash you need and the reserves.
The bottom line
The 30% is not a penalty and it is not aimed at you. It is what the US does with foreign income when it has no other way of collecting, and it applies until you tell it otherwise.
Telling it otherwise takes one number, one form to your manager, one statement to the IRS, and a return every year.
What trips people is not the difficulty. It is that the two central steps look like the same step and are not, and that the people you rely on to help often have not seen this before.
I have been told confidently that I had the wrong form by somebody with an accounting qualification. Ask the question early, and get the ITIN before you need it.
Remember, investing is a game of probabilities. Paying tax on rent you never kept is not one of them.
