Packing up an overseas life and landing back in the United States triggers its own tax return, one that gets far less attention than the year someone leaves. Two tax systems overlap inside the same twelve months on that return. The exclusion built into the departure year budget shrinks to whatever fraction of days still qualify, foreign accounts and funds left behind keep generating filings on their own schedule, and a home sale closed out from abroad runs the proceeds through a currency computation most returnees never see coming. None of that resolves itself just because the move is finished.
Do You Still Get the Foreign Earned Income Exclusion in the Year You Move Back?
Yes, for the days you qualified before your foreign tax home ended, with no cushion beyond that. IRC Section 911(b)(2)(A) requires the exclusion to be computed on a daily basis at an annual rate equal to the full exclusion amount, and Form 2555 carries that math onto the page itself. Line 38 asks for your qualifying days inside the tax year, line 39 divides that by the days in the year to at least three decimal places, and line 40 multiplies the full year maximum by that fraction.
That measuring window is more flexible than most returnees assume. Under the physical presence test, the twelve consecutive months you're measuring against can include days before you ever set foot abroad, because Reg Section 1.911-2(d)(3) allows a window that reaches back before arrival, so a returnee should pick whichever qualifying window pulls the most days into the return year, as long as 330 full days land inside it somewhere. Once the bona fide residence test is satisfied for a full prior tax year, the final partial year counts too, so that test's daily math doesn't restart on the way home. Our Form 2555 exclusion guide covers the day count mechanics, and Form 8938 versus FBAR covers the filings that pair with it.
What If You Move Back Before You Finish the Test?
Then the exclusion for that year is zero. Publication 54 states plainly that a taxpayer who returns to the United States before completing the bona fide residence or physical presence test is not entitled to any exclusion for the period spent abroad. The foreign tax paid on that income can still be claimed as a credit or as an itemized deduction, but the FEIE line on Form 2555 stays at zero.
This is the trap for someone who left mid year and assumed the return trip a year later would automatically bank whatever days they'd racked up. Arrive abroad in mid 2025 and move home in mid 2026 without ever completing a full calendar tax year of residence there, and you've failed the bona fide residence test outright, leaving only the physical presence test's 330 full days inside some qualifying window. Miss that too, and the entire year abroad produces no exclusion.
The One Exception
War or Civil UnrestIRC Section 911(d)(4) lets the IRS waive the minimum time requirement for a specific country during a specific period, but only where war, civil unrest, or similarly adverse conditions forced an early departure. The IRS publishes the qualifying country list each year, and a taxpayer relying on it writes "Claiming Waiver" in the top margin of Form 2555 and attaches a statement, claiming the exclusion only for the days actually resident or present. Our FEIE waiver minimum time requirements guide covers how that claim is documented.
Does the Foreign Housing Exclusion Prorate the Same Way?
Yes, and only for the period you were still qualified. The base housing amount on Form 2555 line 32 is $56.99 per day for 2025, or $20,800 for a full year, and only housing expenses above that base qualify. The standard housing ceiling for locations outside the IRS high cost list runs to $39,000 for a full year or $106.85 per day. Both figures scale down to whatever qualifying days you have left before your tax home moved back to the United States, and expenses count only inside that same qualifying period. A self employed taxpayer claiming the housing deduction gets one extra year to carry forward any unused amount. Our foreign housing exclusion guide has the full mechanics.
Can You Still Deduct the Cost of the Move Home?
No. The moving expense deduction under IRC Section 217 was suspended for civilians starting with the 2018 tax year and was scheduled to return after 2025. It never will. Public Law 119-21, the One Big Beautiful Bill Act, Section 70113(a) struck the words that limited the suspension to years before 2026, which makes the Section 217(k) suspension permanent, with no future return date on the books.
The retiree exception in IRC Section 217(i), for a move to a new US home on bona fide retirement, is still printed in the Code but falls inside the same suspended section, so it produces no deduction either. If an employer reimburses your move home, Reg Section 1.911-3(e)(5)(i) treats that reimbursement as attributable to services performed in the United States, meaning it's taxable and outside the foreign earned income exclusion, unless a written agreement signed before you moved abroad promised the return move regardless of what happened to your job. An oral promise or a verbal company policy is never enough to change that result.
Do You Still Have to File FBAR and Form 8938 After You Move Back?
Yes, for as long as the accounts stay open. The FBAR filing threshold is $10,000 in aggregate value across foreign financial accounts at any point in the year, and the form is due April 15, though FinCEN grants a filing extension to October 15 that applies automatically with no request needed. Where you're living when you file has no bearing on whether the FBAR is owed. Form 8938 works the same way but with different thresholds, and the return year is where the two forms can genuinely diverge.
The abroad thresholds require Section 911(d)(1) qualified individual status for the tax year being reported, so a return year where you failed the test can push you onto the lower domestic thresholds. The year after, the domestic thresholds apply without question. Failing to file Form 8938 carries a flat $10,000 penalty, up to $50,000 more for continued failure after an IRS notice, and a 40% penalty on any underpayment tied to the undisclosed asset. Form 8938 versus FBAR breaks down which form applies to which asset.
What Happens to PFIC Funds and a Foreign Pension You Leave Behind?
They don't close out just because you're home. Every PFIC still needs its own Form 8621 for every tax year in which you receive certain distributions, recognize gain on disposition, make or maintain a qualifying election, or fall under the annual reporting requirement of IRC Section 1298(f). The small account exception for PFIC stock of $25,000 or less, $50,000 joint, disappears in any year you sell, so liquidating foreign funds on the way home forces the full computation for that fund that year.
A foreign pension is treated more gently if it's structured right. Reg Section 1.1298-1(c)(4) lets a participant in a foreign pension fund recognized under a US tax treaty skip the PFIC reporting for the funds that pension holds. Separately, Rev. Proc. 2020-17 exempts certain tax favored foreign retirement trusts from the Form 3520 and 3520-A reporting that would otherwise apply, but that relief is narrow: it does not touch your Section 6038D reporting or your FBAR obligation, both of which keep running regardless. Our PFIC and Form 8621 guide and foreign pension US tax treatment article cover both pieces in depth.
How Is Selling Your Foreign Home Taxed in the Year You Move Back?
The Section 121 home sale exclusion applies to a foreign home exactly the same way it applies to a domestic one, and the statute carries no location requirement at all. You need to have owned and used the property as your main home for two of the five years ending on the sale date, and the exclusion runs to $250,000 for a single filer or $500,000 on a joint return. Renting the property out after you move home and before you sell doesn't create nonqualified use for that later stretch, because IRC Section 121(b)(5) leaves out any part of the five year period after the last date the home served as your main home. Only military, Foreign Service, intelligence, and Peace Corps service get the ten year suspension under Section 121(d)(9); a private sector move abroad and back gets no extension of the five year window.
The Mortgage Payoff Is Where People Get Surprised
Currency RulesEvery amount on your US return has to be reported in dollars, so paying off a foreign currency mortgage runs through a currency translation. IRC Section 988(c)(1)(B)(i) treats becoming the obligor on a debt instrument as a currency transaction, but Section 988(e)(1) turns that treatment off for a personal transaction, which a home mortgage is, and the $200 de minimis rule in Section 988(e)(2) covers only disposing of foreign currency directly, leaving a debt payoff outside it. In practice a currency gain on the payoff can be taxable, while IRC Section 165(c) limits an individual's deductible losses to business, profit seeking, and casualty or theft losses, so a currency loss on a personal home mortgage stays undeductible. Our Section 988 foreign currency gains article and home sale tax exclusion guide cover each half of that computation.
What Happens to Foreign Tax Credit Carryovers Once You're Back in the US?
They can run out with nothing left to absorb them. IRC Section 904(c) allows excess foreign tax credit from a given year to carry back one year and forward ten, but that carryover has to land inside the same income category defined by the Section 904(d) basket rules, and it can only offset tax on foreign source income in that basket. Once you're home earning US source wages, there may be no foreign source income left in the relevant basket for years, which is how a carryover expires unused. The choice of credit against deduction can be revisited within three years of filing or two years of payment, whichever gives more time, and that window is worth checking before a carryover lapses. Our foreign tax credit carryover guide walks through the carryover and basket mechanics.
Is the Return Year a Dual Status Return, and When Is It Due?
No. Dual status filing applies to aliens who change residency status during the year, and a US citizen sits outside that category entirely, reporting worldwide income for the full calendar year every year, moving abroad or moving home included. The automatic extension to June 15 exists only for taxpayers whose tax home and abode are both still outside the United States on the regular due date, so once you're living in the US on April 15, your return is due April 15, with Form 4868 available for the standard extension to October 15 if you need it. An amended return correcting the year has to be filed within three years of filing the original or two years of paying the tax, whichever is later. Our dual status alien tax return article explains who that filing status actually applies to.
Do State Residency and Your Social Security Record Need Attention Too?
Yes, on both counts, and neither one is a federal question. There's no federal rule governing when a state considers you a resident again; each state applies its own domicile test, and the move year is typically a part year resident return. California illustrates how sharp that line can get: its 546 consecutive day safe harbor for a domiciliary working abroad under an employment contract disappears entirely in any year your intangible income, think interest, dividends, and capital gains, exceeds $200,000 while the contract runs. Our state taxes when living abroad guide covers how each state's conformity to the federal exclusion actually works.
On the Social Security side, a totalization agreement only combines your foreign work record with a US benefit if you have at least six quarters of US coverage. Separately, the Social Security Fairness Act, signed January 5, 2025, eliminated the Windfall Elimination Provision and the Government Pension Offset entirely, with increased benefits applied back to January 2024. Our totalization agreements guide has the full mechanics for self employment income earned abroad.
How Do These Return Year Pieces Fit Together?
Coming home swaps one tax system for another mid return, and the pieces run on different clocks. Days logged before the move set the prorated exclusion, and missing either qualifying test wipes it out entirely for that year. Accounts, PFIC funds, and a pension left behind keep their own filing obligations running no matter who is watching them. A foreign home sale draws on the same Section 121 exclusion a domestic sale would, though the mortgage payoff can produce a taxable currency gain with no matching relief on the loss side, since IRC Section 165(c) leaves a personal currency loss nondeductible.
