Selling U.S. Real Estate as a Foreign Owner: The FIRPTA Guide for Breckenridge and Colorado Sellers

If you live outside the United States and own property in Breckenridge, Summit County, or anywhere in Colorado, selling it involves a layer of federal and state tax machinery that domestic sellers never see. None of it is a reason to avoid selling. All of it is manageable with the right sequence and the right team. But the sellers who learn about it at the closing table lose time, liquidity, and sleep. The ones who learn about it two to three months before listing keep control of the process.

This guide explains what actually happens, in plain English, so you can walk into your sale informed.

The single most important thing to understand: withholding is on the gross price, not your gain

Here is the moment that surprises nearly every foreign seller. U.S. law does not wait until tax season to collect from a foreign seller. It collects at the closing table, and it calculates the amount from the full sales price, not from your profit.

Sell a Breckenridge home for $3,000,000 and the standard federal withholding is 15 percent of that gross figure: $450,000. Colorado adds its own withholding of up to 2 percent: $60,000. That is $510,000, roughly 17 percent of the sales price, held back at closing regardless of what you originally paid for the property or what your actual tax will turn out to be.

Withholding is not the tax itself. It is a deposit against the tax, and for most sellers it substantially overshoots the real liability. The rest of this guide is about the two levers that protect your money: reducing what gets withheld before closing, and recovering the excess afterward.

Withholding number one: federal FIRPTA

FIRPTA is the Foreign Investment in Real Property Tax Act. When a foreign person sells U.S. real estate, the law requires the buyer to withhold a percentage of the amount realized, which in a typical sale means the gross sales price, and send it to the IRS.

The standard rate on higher-value property is 15 percent. There are reduced tiers for lower-priced homes that the buyer will use as a residence (no withholding under $300,000, and 10 percent between $300,000 and $1,000,000), but for the luxury mountain market the working assumption is 15 percent of the full price.

Two details worth knowing. First, the legal obligation to withhold sits with the buyer, which is why buyers' agents and title companies take FIRPTA compliance seriously; the paperwork (Forms 8288 and 8288-A) and the remittance run through closing. Second, if the money is simply sent to the IRS at closing, the ordinary path to getting the excess back is filing a U.S. tax return after year end, which can mean waiting a year or more for your own funds. That is the outcome good planning avoids.

Withholding number two: Colorado's 2 percent

This is the one even well-researched international sellers tend to miss, because most FIRPTA articles are written generically and never mention state law.

Under Colorado statute (C.R.S. 39-22-604.5), when a nonresident sells Colorado real estate for more than $100,000, the title company or closing agent must withhold the lesser of 2 percent of the sales price or the seller's net proceeds. The funds are remitted to the Colorado Department of Revenue with Form DR 1079, alongside the informational Form DR 1083, within 30 days of closing.

There is no pre-closing reduction certificate for the Colorado side the way there is for the federal side. The practical play is simpler: know it is coming, budget for it, and understand that it is treated as an estimated payment credited to your Colorado income tax account. You claim it on a Colorado return for the year of sale, and if it exceeds your actual Colorado tax, the difference comes back as a refund.

The proactive play: Form 8288-B, filed before closing

The federal withholding has an escape valve, and timing is everything.

A foreign seller can apply to the IRS for a withholding certificate on Form 8288-B, asking the IRS to reduce the withholding from 15 percent of the gross price down to the seller's actual expected tax on the gain. The critical rule: the application must be filed on or before the closing date.

When an 8288-B application is pending at closing, the buyer still withholds the full amount, but the funds can be held in escrow rather than sent to the IRS while the application is processed. The IRS generally acts on these applications within about 90 days. If the certificate is approved, only the certified amount goes to the IRS and the balance is released back to the seller. The difference between the two paths is stark: money waiting in escrow for roughly three months, versus money sitting at the IRS until a tax return is filed and processed after year end.

Preparing an 8288-B is a job for a U.S. tax professional experienced with foreign sellers. It requires documentation of your purchase price, capital improvements, and expected selling costs, and it requires the seller to have or be applying for a U.S. taxpayer identification number, which brings us to the bottleneck.

The bottleneck nobody warns you about: the ITIN

A foreign seller who has never filed U.S. taxes usually does not have a taxpayer identification number. The 8288-B, and eventually the tax return, both need one.

The application is Form W-7, and the IRS typically takes six to eight weeks to issue an ITIN, longer in peak season. The application also requires certified proof of identity, which for someone living abroad ordinarily means either mailing a passport to the IRS or, far better, working with an IRS Certifying Acceptance Agent who can verify identity without your passport ever leaving your possession.

This is why the smartest first move for a foreign seller is not a listing agreement or a photo shoot. It is engaging the tax professional, who starts the ITIN process as early as your situation allows. Everything downstream, from the 8288-B to the refund, gates on that number existing.

After closing: the 1040-NR and the refund reality

The year after your sale closes, the process reconciles. Your tax professional files a U.S. nonresident income tax return, Form 1040-NR, reporting the actual gain and actual tax, with the withholding credited against it. If more was withheld than you owe, the difference is refunded. A Colorado return does the same job for the state's 2 percent, claiming the DR 1079 credit.

The honest framing: even in a well-run transaction, a foreign seller should expect some portion of their money to be temporarily in the system, either briefly in escrow or, without planning, at the IRS for a year or more. The entire value of the proactive sequence above is shrinking that number and shortening that timeline.

The question worth asking your advisor: U.S. estate tax exposure

There is a second tax issue that has nothing to do with the sale itself, and everything to do with why some foreign owners decide the timing of a sale matters.

A U.S. citizen can currently pass roughly $15 million (the 2026 federal exemption) free of U.S. estate tax. A foreign owner who is not a U.S. resident gets an exemption of just $60,000 on U.S.-situs assets, and U.S. real estate is always a U.S.-situs asset. Above that, federal estate tax rates run as high as 40 percent, and the estate files Form 706-NA. On a multi-million-dollar mountain home, that is exposure most owners have never priced in.

Two mitigating notes. The United States maintains estate tax treaties with a short list of roughly fifteen countries, including Switzerland, Germany, the United Kingdom, France, and Japan, and those treaties can significantly modify or reduce the exposure for owners domiciled there. And a completed sale removes this exposure on the property entirely, because the asset is no longer U.S. real estate.

Whether this factors into your decision is a conversation for your estate and tax advisors, not your real estate broker. But it belongs on the list of questions you bring them, because it is the item most often discovered too late.

Selling from abroad: the practical logistics

The transaction mechanics are more solvable than most overseas owners expect.

Signing. Colorado closings can typically be handled without flying back. Remote online notarization is widely used, and where a wet signature is required, documents can be notarized abroad through a U.S. embassy or consulate or authenticated by apostille in Hague Convention countries. Your title company will specify which path fits your documents.

Property access. Showings, staging, inspections, repairs, and contractor access are all managed locally by your listing broker. A vacant or lightly used home is an advantage here, not a problem.

Communication. Time zones are a workflow question, not an obstacle. My international clients get updates scheduled to their evening, and decisions rarely need to happen inside a single business day.

Funds. Sale proceeds wire internationally through the title company. Currency conversion strategy is worth a conversation with your bank before closing, since exchange timing on a seven-figure wire is its own financial decision.

Who does what

A foreign-owner sale runs on a small team with clear lanes:

• U.S. tax professional (foreign-seller specialist): the engine. Obtains the ITIN, prepares and files the 8288-B, calculates the actual tax, files the 1040-NR and Colorado return, recovers refunds. Engaged first, ideally before listing.
• Listing broker: the quarterback. Prices and markets the property, manages access and negotiations, coordinates every party to the sequence above so deadlines are met, and makes sure the contract timeline leaves room for the tax machinery.
• Title company / closing agent: executes the withholding on both the federal and Colorado sides, handles escrow arrangements when an 8288-B is pending, remits DR 1079 and DR 1083, and wires proceeds.
• Estate or tax counsel in your home country: coordinates treaty questions and home-country tax treatment of the sale.

Common pitfalls

• Learning about withholding at the closing table. By then the 8288-B option is gone for practical purposes. The planning window is before and during listing, not at contract.
• Starting the ITIN late. The six to eight week W-7 timeline gates everything. A fast sale to a cash buyer can outrun the paperwork if the ITIN was not started early.
• Assuming FIRPTA is the whole story. Colorado's 2 percent is separate, automatic, and absent from most FIRPTA articles written for a national audience.
• Mailing a passport to the IRS. A Certifying Acceptance Agent exists precisely so you never have to.
• Letting anyone but a tax professional calculate the tax. Brokers, title officers, and articles like this one can explain the process. Only your tax professional should put a number on your gain, your tax, or your refund.
• Ignoring how title is held. Withholding and certificates apply per owner. If the property is held jointly, or by an entity or trust, the paperwork multiplies and the tax analysis changes. Confirm the vesting on your deed before anything else.

Frequently asked questions

How much is withheld when a foreign owner sells a home in Breckenridge or elsewhere in Colorado?

The standard federal FIRPTA withholding is 15 percent of the gross sales price for higher-value property, and Colorado separately withholds the lesser of 2 percent of the sales price or the seller's net proceeds. On a $3,000,000 sale, that is roughly $510,000 held at closing. Withholding is a deposit against tax, not the tax itself, and it is frequently reduced in advance or recovered afterward.

Is FIRPTA withholding the same as my actual tax?

No. FIRPTA withholding is calculated from the gross sales price, while your actual U.S. tax is based on your gain after purchase price, capital improvements, and selling costs. For most sellers the withholding overshoots the real liability, which is why the Form 8288-B process and the post-sale tax return exist.

What is Form 8288-B and when must it be filed?

Form 8288-B is an application asking the IRS to reduce FIRPTA withholding to the seller's actual expected tax. It must be filed on or before the closing date. When an application is pending at closing, the withheld funds can be held in escrow instead of being sent to the IRS, and the IRS generally decides within about 90 days.

Do I need a U.S. tax ID to sell as a foreign owner?

You will need an ITIN (Individual Taxpayer Identification Number) for the withholding certificate and the tax return. The application is Form W-7 and typically takes six to eight weeks, so starting it early is the single most time-sensitive step in a foreign-owner sale. An IRS Certifying Acceptance Agent can verify your identity without you mailing your passport.

Does Colorado have its own withholding on foreign or out-of-state sellers?

Yes. Under C.R.S. 39-22-604.5, sales of Colorado real estate over $100,000 by nonresident sellers are subject to withholding of the lesser of 2 percent of the sales price or the net proceeds, collected by the closing agent and remitted on Form DR 1079. It is credited as an estimated payment on the seller's Colorado income tax return, where any excess is refunded.

Can I sell my Colorado property without traveling back to the United States?

In most cases, yes. Colorado transactions routinely close with remote online notarization, and documents requiring wet signatures can be notarized at a U.S. embassy or consulate or authenticated by apostille in Hague Convention countries. Showings, inspections, and closing logistics are handled locally by your listing broker and title company.

Why does U.S. estate tax come up when foreign owners think about selling?

A nonresident foreign owner's U.S. estate tax exemption is only $60,000 on U.S.-situs assets such as real estate, compared with roughly $15 million for U.S. citizens in 2026, with rates up to 40 percent above the exemption. Estate tax treaties with roughly fifteen countries, including Switzerland, Germany, and the United Kingdom, can reduce that exposure, and selling the property removes it for that asset. Whether it should influence your timing is a question for your tax and estate advisors.

Selling from abroad, without the surprises

Over ten years and roughly $150 million in closed transactions across Summit County and the Colorado mountains, the pattern with international sellers is always the same: the tax machinery is manageable, and the sequence is everything. My role is to quarterback that sequence, connect you with vetted U.S. tax professionals who specialize in foreign sellers, keep the contract timeline aligned with the paperwork, and market the property to the buyers a home like yours deserves, while you stay home.
