Your Dual-Status Return After Renouncing
The year you renounce is taxed in two halves on one dual-status return. What changes, where Form 8854 attaches, and how credits split.
The year you renounce is taxed in two halves on one dual-status return. What changes, where Form 8854 attaches, and how credits split.
The year you renounce US citizenship is taxed in two halves. Up to your expatriation date you are a citizen taxed on worldwide income; from that date you are a nonresident taxed only on US-source income. Both halves go on one dual-status return: usually Form 1040-NR, with a Form 1040 statement and Form 8854 attached.
Most guides stop at "file a final dual-status return". But this is the one return where two sets of rules run side by side for the same calendar year, and choices made on it, such as foreign tax allocation, a spouse election and the timing of payments, cannot be revisited, because most former citizens never file again. This guide works through that one return. The wider process of giving up citizenship is covered in our guide to renouncing US citizenship.
A dual-status year is any tax year in which you are a US citizen or resident for part of the year and a nonresident alien for the rest. The IRS taxes each part under its own rules. For the resident period you are taxed on income from all sources. For the nonresident period you are taxed only on US-source income and on certain foreign income effectively connected with a US trade or business (IRS: taxation of dual-status individuals).
Renunciation produces exactly that split. Individuals get no short tax year on leaving, so the calendar year runs to its end, taxed in two segments.
The dividing line is your expatriation date. For someone who renounces before a US consular officer, that is the date of the renunciation oath, provided the State Department later confirms it by issuing a Certificate of Loss of Nationality. The Instructions for Form 8854 set out the rule under the date of relinquishment of citizenship, and the certificate normally records the date you swore the oath, not the date it reaches you. If you are still waiting, our note on how long a CLN takes explains why the delay does not move the tax date.
The day before the expatriation date is the last day of the citizen period. It matters twice: it is the day a covered expatriate's property is treated as sold, and it is the cut-off for which income goes on the Form 1040 statement rather than the Form 1040-NR.
Both, in a set arrangement. The IRS rule turns on your status at the end of the year:
The second case is unusual for a former citizen but not impossible. If you stay in the United States after renouncing, you may meet the substantial presence test as an alien for the rest of the year, which changes the structure of the whole return. That needs professional review before anything is prepared.
Forums are full of people who filed only a partial-year Form 1040 because they had no later US income. The published rule is the dual-status format. This return also carries your Form 8854 certification, so it is not the place to cut corners.
| Citizen period (Form 1040 statement) | Nonresident period (Form 1040-NR) | |
|---|---|---|
| Runs | January 1 to the day before the expatriation date | Expatriation date to December 31 |
| Income taxed | Worldwide income received in the period | US-source income, plus foreign income effectively connected with a US business |
| Foreign earned income | Foreign earned income exclusion may apply, prorated to qualifying days | Outside US tax |
| US passive income | Taxed at graduated rates with other income | Taxed at a flat statutory or treaty rate, usually withheld at source |
| Deductions | Itemised only; no standard deduction | Only deductions connected with effectively connected income |
| Filing status | No joint return or head of household unless the spouse election is made | Married-filing-separately rates if married and no election |
| Foreign tax credit | Foreign tax on foreign-source income of the period (Form 1116) | Generally only foreign tax on effectively connected income |
| Treaty benefits | Generally unavailable to a citizen | Available for the nonresident part of the year |
The restrictions are set out in chapter 6 of IRS Publication 519, and they bite hardest on the citizen period:
Often the effect is small, because the foreign earned income exclusion or foreign tax credit already brings citizen-period tax to nil. Where income is unsheltered, such as US dividends or a large gain, losing the standard deduction is a real cost.
Possibly, and this is the point most pages miss. Publication 519 lets a married couple choose to treat a nonresident or dual-status spouse as a US resident if, at the end of the year, one spouse is a US citizen or resident. If they choose it, both are treated as residents for the entire tax year and taxed on worldwide income, the dual-status restrictions fall away, and they file jointly.
For a renouncer that is double-edged. It restores joint rates and the standard deduction, but it also pulls your foreign income for the months after renunciation back into US tax, often the reverse of what you set out to do. Whether the election is available and wise alongside an expatriation is a judgement our Enrolled Agent reviewer makes case by case, and it should be modelled both ways before anyone ticks the box.
Foreign tax credits follow the income they relate to. For the citizen period, you claim credit on Form 1116 for foreign income tax on foreign-source income included in that period, as in earlier years. For the nonresident period, IRS Publication 514 says a nonresident alien cannot take the credit in most cases, the main exception being foreign tax on foreign-source income effectively connected with a US trade or business.
The awkward part is timing. Most foreign tax years do not match the US calendar year. A UK resident, for example, is taxed on a year running April to April, so one foreign tax bill can cover income from both sides of your expatriation date. Only the share attributable to income on the Form 1040 statement is creditable there, and that allocation needs workings, not an estimate.
The final year is also the last practical chance to use foreign tax credit carryovers. Once you are taxed only on US-source income, foreign tax credits rarely have anything to offset, so unused credits from earlier years are stranded in practice. Our note on foreign tax credit carryovers explains how they are tracked.
The test is broadly when you receive income, not when you earned it. Publication 519 states that foreign-source income received while you are a nonresident is not taxable, even if you earned it while you were a resident. So a foreign bonus earned in the spring but paid after your expatriation date would normally fall outside US tax, while one paid the day before would be fully in.
Three cautions apply. US-source income is taxable on either side of the line. Covered expatriates face separate rules for deferred compensation, which can tax the value of an accrued benefit or put later payments under withholding. And capital gains depend on when the sale happens: a disposal of a foreign asset on the day before your expatriation date is a citizen-period gain, while the same sale a week later is generally outside US tax. Where significant income or gains sit close to the date, timing deserves professional review before the appointment is booked, not after.
Every former citizen files an initial Form 8854, Initial and Annual Expatriation Statement, for the expatriation year, covered or not. The instructions say to attach it to your income tax return for that year, which here is the dual-status Form 1040-NR. Form 8854 is also where you certify compliance with US federal tax obligations for the years before expatriation; failing to certify makes you a covered expatriate whatever your wealth or tax history.
If you are a covered expatriate, section 877A treats your worldwide property as sold at fair market value on the day before your expatriation date. That day falls in the citizen period, so the resulting gain, after the exclusion amount set for your expatriation year, belongs on the citizen-period side of the return. Alongside the deemed sale:
You can also elect to defer payment of the deemed-sale tax, which requires security and annual Form 8854 filings. The IRS expatriation tax page sets out the covered-expatriate tests, and our exit tax guide covers planning before the date.
Not by default. From the following year you are a nonresident alien with no worldwide filing obligation. You file Form 1040-NR only if you have US-source income that requires a return, such as rent from US property taxed on a net basis, US business income, or passive income where too little tax was withheld.
There are exceptions. A covered expatriate who deferred the deemed-sale tax, holds eligible deferred compensation, or has an interest in a non-grantor trust files Form 8854 every year until those items are finished. And a covered expatriate's later gifts or bequests to US persons can be taxed in the recipient's hands.
Collect income records split at the expatriation date, foreign tax assessments that let you allocate tax by period, a dated balance sheet for the day before expatriation if covered status is possible, and your compliance history for the certification. Your FBAR and any Form 8938 still apply for the citizen period.
