You do not automatically owe U.S. tax: a qualifying work move likely gives you an exclusion large enough to cover the gain, but without an exception the gain is taxable if you were a U.S. citizen or tax resident when the sale closed.
“I moved to the US and sold my property in Ireland for a €55k profit, which is tax-free there. I lived in the house for 23 months and 24 days before moving. Will I owe US taxes on this sale because I missed the 2-year primary residence rule by a single week?”
Summary
A seven-day shortfall does not automatically make the whole gain taxable: a qualifying exception reduces the maximum exclusion rather than taxing everything. If your shortest qualifying period was exactly 723 days, the individual cap would still be about $247,603—likely enough for this sale after the gain is properly recalculated in dollars.
Your federal result depends first on your U.S. tax status on the closing date and then, if you were taxable as a U.S. person, which home-sale exclusion applies.
If you were neither a U.S. citizen nor a when the sale closed, the Irish real-property gain is foreign-source under 26 USC 862(a)(5). It generally is not federally taxable during the nonresident part of a dual-status year unless it was effectively connected with a U.S. trade or business [IRS Publication 519, p. 45].
On your current count, 23 months and 24 days does not satisfy the required 24 full months or 730 days of both ownership and use within the five-year period [26 USC 121(a); 26 CFR 1.121-1(c)]. Recount actual days and any other qualifying use within that window—periods need not be continuous, and short temporary absences can count—but the full exclusion is unavailable if the final total remains below 730 days.
If the primary reason for selling was a job change, the is likely your strongest route. The safe harbor applies when the employment change occurred while you owned and used the home and the new workplace was at least 50 miles farther from it than the old workplace—or at least 50 miles away if there was no old workplace; employment includes a new employer, the same employer, or self-employment [26 CFR 1.121-3(c)]. Health or qualifying unforeseen circumstances are alternative grounds [26 CFR 1.121-3(d)–(e)]. If the shortest qualifying period was exactly 723 days and there was no limiting prior sale, the single-filer cap would be about $247,603, so a properly calculated gain near €55,000 would ordinarily fit below it [26 CFR 1.121-3(g)(1)].
If you were a U.S. citizen or resident when the sale closed, remained short of 730 days, and the sale was not primarily caused by work, health, or unforeseen circumstances, section 121 does not exclude the gain. Your U.S.-dollar gain is then reportable, although the actual tax depends on the rest of your return [IRS Publication 519, p. 45; IRS Publication 523, p. 20].
These are federal branches; every resident branch uses the gain calculated in U.S. dollars, not the Irish €55,000 figure.

Next steps
These steps determine whether the sale is federally taxable, calculate the correct gain, and put it on the right return only if required.
Start here
Place the closing date in your U.S. tax timeline
Identify whether you were a U.S. citizen or on the closing date. For a green card received abroad, the IRS starting date is the first day you were physically present in the United States after receiving it; where both the green-card and substantial-presence tests are met, use the earlier IRS starting date. A foreign-property sale completed during a nonresident-alien period is generally outside federal tax unless effectively connected with a U.S. trade or business [IRS Residency Starting and Ending Dates; IRS Publication 519, p. 45].
Requirements
If taxable as a U.S. person
Count your use and test the move exception
Count actual ownership and principal-residence days in the five years ending at closing. If the total remains below 730, test the work safe harbor using the workplace addresses; if it fails, test whether work, health, or an unforeseen event was nevertheless the primary reason for sale. With exactly 723 days as the shortest period and no shorter prior-sale interval, the is 723 ÷ 730 × $250,000 = $247,602.74 [26 CFR 1.121-3].
Requirements
Before comparing gain with the cap
Recalculate the gain in U.S. dollars
Calculate amount realized as sale price minus selling expenses, then subtract your . If you bought the property, begin with historical cost, add qualifying improvements and make required adjustments; translate each relevant foreign-currency item using the exchange rate when received, paid, or accrued. Do not treat €55,000 converted at one current rate as the final U.S. gain [26 USC 1012; IRS Foreign Currency and Currency Exchange Rates; IRS Publication 523].
Requirements
With the return for the sale year
File the sale only if the rules require it
If all gain is excluded and you received no Form 1099-S, Publication 523 says the sale need not appear on the federal return. If any gain is taxable or you received Form 1099-S, report it on Form 8949 and Schedule D with Form 1040; a calendar-year return is due April 15 following the sale year, so a 2026 sale is due April 15, 2027 [IRS Publication 523, p. 20; 26 USC 6072(a)].

Legal sources
The answer comes from Internal Revenue Code §§121, 862, 1012, and 6072, Treasury Regulations §§1.121-1 and 1.121-3, and current IRS guidance.
26 USC 121
This statute supplies the full two-year exclusion, the $250,000 individual cap, and the depreciation carve-out.
§121(a), (b)(1), and (d)(6)
Gross income shall not include gain from the sale or exchange of property if, during the 5-year period ending on the date of the sale or exchange, such property has been owned and used by the taxpayer as the taxpayer's principal residence for periods aggregating 2 years or more. The amount of gain excluded from gross income under subsection (a) with respect to any sale or exchange shall not exceed $250,000. Subsection (a) shall not apply to so much of the gain from the sale of any property as does not exceed the portion of the depreciation adjustments (as defined in section 1250(b)(3)) attributable to periods after May 6, 1997, in respect of such property.
26 CFR 1.121-3
This regulation establishes the employment-move safe harbor and the formula for the reduced exclusion.
(c)(2)–(3), (g)(1)
A sale or exchange is deemed to be by reason of a change in place of employment (within the meaning of paragraph (c)(1) of this section) if—(i) The change in place of employment occurs during the period of the taxpayer's ownership and use of the property as the taxpayer's principal residence; and (ii) the qualified individual's new place of employment is at least 50 miles farther from the residence sold or exchanged than was the former place of employment, or, if there was no former place of employment, the distance between the qualified individual's new place of employment and the residence sold or exchanged is at least 50 miles. For purposes of this paragraph (c), employment includes the commencement of employment with a new employer, the continuation of employment with the same employer, and the commencement or continuation of self-employment. The reduced maximum exclusion is computed by multiplying the maximum dollar limitation of $250,000 ($500,000 for certain joint filers) by a fraction. The numerator of the fraction is the shortest of the period of time that the taxpayer owned the property during the 5-year period ending on the date of the sale or exchange; the period of time that the taxpayer used the property as the taxpayer's principal residence during the 5-year period ending on the date of the sale or exchange; or the period of time between the date of a prior sale or exchange of property for which the taxpayer excluded gain under section 121 and the date of the current sale or exchange. The denominator of the fraction is 730 days or 24 months (depending on the measure of time used in the numerator).
26 CFR 1.121-3
Health and unforeseen circumstances can provide alternative grounds for a reduced exclusion.
(d)(1), (e)(1)
A sale or exchange is by reason of health if the primary reason for the sale or exchange is to obtain, provide, or facilitate the diagnosis, cure, mitigation, or treatment of disease, illness, or injury of a qualified individual described in paragraph (f) of this section, or to obtain or provide medical or personal care for a qualified individual suffering from a disease, illness, or injury. A sale or exchange is by reason of unforeseen circumstances if the primary reason for the sale or exchange is the occurrence of an event that the taxpayer could not reasonably have anticipated before purchasing and occupying the residence.
26 CFR 1.121-1
This regulation explains how to count the two years, including noncontinuous use and short temporary absences.
(c)(1)–(2)
The requirements of ownership and use for periods aggregating 2 years or more may be satisfied by establishing ownership and use for 24 full months or for 730 days (365 × 2). The requirements of ownership and use may be satisfied during nonconcurrent periods if both the ownership and use tests are met during the 5-year period ending on the date of the sale or exchange. In establishing whether a taxpayer has satisfied the 2-year use requirement, occupancy of the residence is required. However, short temporary absences, such as for vacation or other seasonal absence (although accompanied with rental of the residence), are counted as periods of use.
IRS Publication 519 (2025)
This publication draws the decisive line between the resident and nonresident portions of a dual-status year.
page 45
For the part of the year you are a resident alien, you are taxed on income from all sources. Income from sources outside the United States is taxable if you receive it while you are a resident alien. For the part of the year you are a nonresident alien, you are taxed on income from U.S. sources and on certain foreign source income treated as effectively connected with a U.S. trade or business. Income from sources outside the United States that is not effectively connected with a trade or business in the United States is not taxable if you receive it while you are a nonresident alien.
26 USC 862(a)(5)
An Irish property is real property outside the United States, making the sale gain foreign-source.
§862(a)(5)
gains, profits, and income from the sale or exchange of real property located without the United States;
IRS Residency Starting and Ending Dates
This IRS page helps place the closing date before or after the federal residency starting date.
If you receive your green card abroad, then the residency starting date is your first day of physical presence in the United States after you receive your green card. If you meet both the green card test and the substantial presence test in the same year, your residency starting date is the earlier of: The first day you are present in the United States during the year you pass the substantial presence test, or The first day you are present in the U.S. as a lawful permanent resident (green card holder).
IRS Foreign Currency and Currency Exchange Rates
The Irish sale figures must be translated into dollars at the relevant transaction times.
You must express the amounts you report on your U.S. tax return in U.S. dollars. If you receive all or part of your income or pay some or all of your expenses in foreign currency, you must translate the foreign currency into U.S. dollars. Use the exchange rate prevailing when you receive, pay, or accrue the item.
26 USC 1012(a)
For purchased property, the general U.S. starting-basis rule is historical cost.
§1012(a)
The basis of property shall be the cost of such property, except as otherwise provided in this subchapter and subchapters C (relating to corporate distributions and adjustments), K (relating to partners and partnerships), and P (relating to capital gains and losses).
IRS Foreign Tax Credit
With no Irish income tax paid or accrued on the gain, there is no such foreign tax to credit.
If you paid or accrued foreign taxes to a foreign country or U.S. possession and are subject to U.S. tax on the same income, you may be able to take either a credit or an itemized deduction for those taxes. You can claim a credit only for foreign taxes that are imposed on you by a foreign country or U.S. possession.
IRS Publication 523 (2025)
This publication determines when an excluded or taxable home sale must appear on the return.
page 20
You need to report the gain if ANY of the following is true. • You have taxable gain on your home sale (or on the residential portion of your property if you made separate calculations for home and business) and don’t qualify to exclude all of the gain. • You received a Form 1099-S. If so, you must report the sale on Form 8949 even if you have no taxable gain to report. • You wish to report your gain as a taxable gain even though some or all of it is eligible for exclusion. If NONE of the three bullets above is true, you don’t need to report your home sale on your tax return.
26 USC 6072(a)
A calendar-year individual return is generally due April 15 following the sale year.
§6072(a)
In the case of returns under section 6012, 6013, or 6017 (relating to income tax under subtitle A), returns made on the basis of the calendar year shall be filed on or before the 15th day of April following the close of the calendar year
These are the official federal rules as published or current on the cited dates; tax rules and forms can change.
