US tax forms for expats: complete 2026 filing guide
Most expat tax obligations begin with Form 1040 and branch into additional forms depending on income type, account balances, and foreign entity interests.
For tax year 2025, a single filer under 65 generally must file once gross income reaches $15,750. That obligation follows citizenship, not location.
Which specific US expat tax forms apply depends on whether you claim a credit, an exclusion, or both – and on whether you hold foreign accounts or business interests abroad.
In this article, you’ll find:
- The most common tax forms for US citizens living abroad and what triggers each one
- Current 2025 exclusion limits, thresholds, and confirmed 2026 figures
- Exact deadlines for the 2026 filing season
- Scenario-based guidance on which forms apply to your situation
- The structural mistakes that most often lead to penalties
What are the US tax forms for expats abroad?
There is no special tax for US citizens living abroad – you file the same Form 1040 as domestic filers, with additional international forms as needed. FBAR and Form 8938 are filed separately when their thresholds are met.
Not every expat files every form – what applies to you depends on your income type, foreign asset values, account balances, entity ownership, and whether you claim a credit or exclusion.
The obligation to file follows citizenship, not location. A US citizen earning a salary in France, holding a bank account in Germany, and owning shares in a local company could need Form 1040, FBAR, Form 8938, and a foreign entity form – all for the same tax year.
The table below covers the most common IRS tax forms for expats, who files each one, what triggers the requirement, and where it is filed.
| Form | Who files | Main trigger | Filed with | Due date |
|---|---|---|---|---|
| Form 1040 | US citizens and resident aliens | Gross income above the filing threshold based on status and age | IRS | April 15 – June 15, automatic expat extension |
| Form 2555 | Expats claiming the FEIE | Foreign earned income; exclusion up to $130,000 for 2025 | Attached to Form 1040 | Same as Form 1040 |
| Form 1116 | Taxpayers paying foreign income tax | Foreign tax paid or accrued on foreign-source income | Attached to Form 1040 | Same as Form 1040 |
| Form 8938 | Expats with specified foreign financial assets | Single abroad: over $200,000 year-end or $300,000 at any point; MFJ: over $400,000 year-end or $600,000 at any point | Attached to Form 1040 | Same as Form 1040 |
| FBAR – FinCEN Form 114 | US persons with foreign accounts | Aggregate value exceeded $10,000 at any point during the year | FinCEN, not IRS | April 15 – October 15, automatic extension |
| Form 4868 | Any taxpayer needing more time | Filed to extend beyond June 15 | IRS | File by June 15, 2026 – extends to October 15 |
| Form 5471 | US persons with interests in foreign corporations | Ownership, control, or specified transactions involving a foreign corporation | Attached to Form 1040 | Same as Form 1040 |
Neither Form 2555 nor Form 1116 is required solely because you earn foreign income – each applies when you actively claim the exclusion or credit. Some taxpayers file both in the same year for different income categories.
See our full US expat tax guide for the complete picture of filing obligations, deadlines, and double-taxation relief.
Who needs to file US expat tax forms?
Because the US taxes on citizenship, Americans living abroad owe taxes on worldwide income. The filing obligation does not end simply because you pay tax in your country of residence.
Gross income – not physical location – triggers the filing requirement. Meeting the threshold means a return is due.
You may need to file if:
- Your gross income exceeds the standard deduction for your filing status – $15,750 single, $31,500 married filing jointly, $23,625 head of household for 2025
- You have net self-employment income of $400 or more
- The aggregate value of your foreign financial accounts exceeded $10,000 at any point during the year – this triggers an FBAR
- Your specified foreign financial assets exceed the Form 8938 thresholds
- You own or control a foreign corporation, partnership, or disregarded entity
- You hold interests in foreign mutual funds or ETFs classified as PFICs under US rules
Filing is required even when credits and exclusions reduce your US tax to zero. The obligation to file and the obligation to pay are separate – skipping the return means you cannot claim FEIE, FTC, or any other benefit.
See our guide on whether US citizens abroad must pay taxes for a deeper look at filing thresholds and worldwide income rules.
Which expat tax forms apply to you?
Every US citizen living abroad has tax obligations that go beyond the federal return – international information forms, foreign account reports, and entity disclosures may all apply depending on your situation.
The same brackets, rates, and filing thresholds that apply domestically also apply abroad. The difference is the additional reporting layer.
You live abroad and earn income
Form 1040 is the baseline for every US citizen or resident alien who meets the income threshold. For tax year 2025, a single filer under 65 generally must file once gross income reaches $15,750.
You earn a foreign salary or run a business abroad
A US citizen working abroad may use Form 2555 to claim the FEIE.
Form 1116 claims the foreign tax credit instead.
Neither form is automatically required – each applies when you actively claim the benefit.
Some taxpayers file both in limited circumstances for different income categories.
You hold foreign bank or financial accounts
If the aggregate value of all your foreign accounts exceeded $10,000 at any point in 2025, you must file FinCEN Form 114. This is a separate obligation filed through the FinCEN BSA e-Filing system – not with the IRS.
The threshold is aggregate: a checking account with $6,000 and a savings account with $5,000 together cross it.
You hold significant foreign assets
Expats whose specified foreign financial assets exceed $200,000 at year-end or $300,000 at any point – single filer, living abroad – must file Form 8938.
Many expats who file FBAR also need Form 8938 – the two are not interchangeable.
You own a foreign corporation, partnership, or fund
Form 5471, Form 8865, and Form 8621 each target a different foreign structure.
These are among the most commonly missed expat forms.
Forms 5471 and 8865 carry starting penalties of $10,000 per form, per year.
Form 8621 follows separate PFIC rules, and missing a required filing can keep the assessment period open under section 6501(c)(8) until the form is received.
Which forms do you need by expat situation?
Your expat tax filing package depends on your income type, foreign accounts, entity ownership, and whether you claim a credit or exclusion.
The table below maps each common situation to the forms you likely need, from salaried employment to foreign fund holdings.
| Your situation | Likely forms | Key note |
|---|---|---|
| Salaried employee abroad, low-tax country | Form 1040, Form 2555 | FEIE can exclude up to $130,000 of earned income for 2025 |
| Salaried employee abroad, high-tax country | Form 1040, Form 1116 | FTC offsets US tax by foreign taxes paid |
| Freelancer or self-employed abroad | Form 1040, Schedule SE, Form 2555 or 1116 | Self-employment tax still applies even with FEIE |
| Investor with foreign brokerage accounts | Form 1040, FBAR, Form 8938, possibly Form 8621 | Foreign mutual funds and ETFs often classify as PFICs |
| Owner of a foreign corporation | Form 1040, Form 5471, FBAR, Form 8938 | Penalties start at $10,000 per form |
| Partner in a foreign business | Form 1040, Form 8865, FBAR, Form 8938 | Schedules K-2 and K-3 may apply depending on international items |
| Retiree abroad with pension and accounts | Form 1040, Form 1116, FBAR, Form 8938 | Pension income does not qualify for FEIE |
| Dual citizen who has never filed | Form 1040, FBAR, Form 8938, plus entity forms if applicable | Streamlined filing may apply for non-willful non-filers |
Form 1040: your annual US tax return
Form 1040 is the base document in every expat tax return – all other international forms attach to it or are filed alongside it.
Who files
US citizens and resident aliens with gross income above the applicable threshold must file Form 1040.
Taxes for US citizens living abroad are calculated on Form 1040 using the same rates and standard deduction as domestic filers – $15,750 single, $31,500 MFJ for 2025.
What income counts
The IRS taxes US citizens on worldwide income – wages, self-employment income, dividends, rental income, and capital gains all count, regardless of where earned.
For tax year 2025, the standard deduction is $15,750 for single, $31,500 for MFJ, and $23,625 for head of household.
Deadline
Qualifying taxpayers abroad generally have until June 15, 2026, to file and pay without a failure-to-pay penalty under the automatic two-month extension.
Interest on unpaid tax runs from April 15, 2026, regardless of the extension. To extend further to October 15, 2026, file Form 4868 by June 15.
Common attachments
Most expats attach at least one of the following to their Form 1040:
- Form 2555 to claim the FEIE
- Form 1116 to claim the foreign tax credit
- Form 8938 if foreign asset thresholds are met
- Schedules for any foreign business or investment interests
Example: A US teacher abroad earning $65,000 in salary would file Form 1040 with Form 2555 to exclude the salary under FEIE. A freelance consultant earning $140,000 would file Form 1040, Form 2555 – excluding $130,000 – and Schedule SE for self-employment tax on the full amount. FEIE does not eliminate SE tax.
See our Form 1040 guide for line-by-line instructions.
Form 2555 and foreign income exclusion
Form 2555 is the IRS form used to claim the Foreign Earned Income Exclusion, or FEIE. For tax year 2025, the exclusion limit is $130,000 per qualifying taxpayer, rising to $132,900 for 2026.
Form 2555 can exclude up to $130,000 for 2025 of qualifying earned income, which is the primary reason US citizens living abroad pay taxes at a significantly lower effective rate than the statutory brackets suggest.
Who qualifies
To qualify, a taxpayer must have a foreign tax home and meet one of two tests:
- The physical presence test requires 330 full days in a foreign country within any 12-month period
- The bona fide residence test requires residence in a foreign country for an entire tax year, judged by lifestyle, intent, and ties abroad
What income qualifies – and what does not
Wages and self-employment income earned abroad qualify. Dividends, capital gains, rental income, and other passive income do not. The exclusion applies strictly to income earned through active work. Self-employment tax is not eliminated by claiming FEIE.
When FEIE is not the best choice
If you live in a high-tax country where the local tax rate exceeds the US rate, Form 1116 and the foreign tax credit will likely reduce your US bill further. Many expats calculate both options before choosing.
NOTE! Many taxpayers combine FEIE with the foreign housing exclusion for added savings. For 2025, the housing base amount is $20,800 – equal to 16% of the FEIE – with a standard cap of $39,000 – equal to 30% of the FEIE. For 2026, the base increases to $21,264 with a cap of $39,870.
See our FEIE guide for a full walkthrough of eligibility, calculations, and the housing exclusion.
Form 1116: your guide to claiming the foreign tax credit (FTC)
When the taxation of US citizens living abroad results in a double-tax overlap, Form 1116 offsets your US liability by crediting the qualified foreign income taxes you already paid.
The credit is capped at the lesser of the foreign tax paid or the US tax attributable to your foreign-source income.
FTC is particularly valuable for expats in high-tax countries like Germany, France, or Japan, where local rates often exceed the US rate.
Key FTC rules:
- The credit is calculated separately per income category – general, passive, foreign branch, and others
- Unused credits carry back 1 year and forward 10 years
- If your creditable foreign taxes are $300 or less – $600 MFJ – and all foreign income is in the passive category, you can claim the credit without filing Form 1116
- You cannot claim FTC on income excluded under FEIE – the two do not stack on the same dollars
See our foreign tax credit guide for a detailed walkthrough of the limitation formula and carryover rules.
FEIE vs FTC: which works better for you?
A US citizen living abroad pays taxes to both the US and the country of residence – FEIE and FTC are the two primary tools to reduce that overlap, and each addresses different income types.
The right combination of FEIE and FTC can often reduce US taxes for citizens living abroad to zero, but the two cannot both apply to the same earned income in the same way.
| FEIE – Form 2555 | FTC – Form 1116 | |
|---|---|---|
| Best for | Low- or no-tax countries; earned income | High-tax countries; mixed income types |
| What it covers | Wages and self-employment income only | Most foreign income types on which qualified tax was paid |
| 2025 limit | $130,000 exclusion per person | Credit for foreign taxes paid, subject to FTC limitation |
| 2026 limit | $132,900 | Same formula, updated brackets |
| Carryover | None | Unused credits carry back 1 year, forward 10 |
| Can you combine? | Yes, with the housing exclusion | Yes, with FEIE on different income categories |
| Self-employment tax | Not eliminated | Not directly offset – SE tax is a separate calculation |
Based on a TFX client scenario: a US consultant in the UAE claimed the 2025 FEIE of $130,000, reducing federal tax liability to $0. A comparable client in Germany, where income tax rates can exceed 40%, used FTC instead – the credit offset the full US liability with credits left to carry forward.
The IRS carryover rules let unused credits roll back one year and forward for 10, which is valuable when foreign tax payments vary between years.
How to choose between FEIE and FTC
The choice between FEIE and FTC depends on your country’s tax rate, your income type, and your long-term tax position.
- If your foreign tax rate is low or zero – UAE, Singapore, Bahamas – FEIE is usually the better starting point. It excludes up to $130,000 for 2025 of earned income from US tax without needing to show foreign taxes paid.
- If your foreign tax rate exceeds the US rate – Germany, France, Japan, Scandinavia – FTC typically produces a better result. The credit offsets your full US liability, and excess credits carry forward for up to 10 years.
- If you have both earned and passive income, you may use FEIE on your salary and FTC on investment income – but you cannot claim both on the same earned income. The FTC limitation formula applies separately per income category.
- If you are self-employed, FEIE excludes the income from federal income tax but does not eliminate self-employment tax. The 12.4% Social Security portion applies only up to the $176,100 wage base for 2025, but the 2.9% Medicare portion applies to all self-employment earnings with no cap, and an additional 0.9% Medicare tax applies above $200,000 for single filers or $250,000 for MFJ. A totalization agreement between the US and your country of residence may eliminate the overlap.
See our FEIE vs FTC comparison for worked examples with salary and freelance income.
Form 8938 (FATCA) vs FBAR: key differences
Many expats need to file both Form 8938 and FinCEN Form 114. They cover different assets, different thresholds, and go to different agencies.
An American living abroad pays taxes on worldwide income and must separately report foreign financial assets when they exceed the applicable thresholds.
Form 8938 covers specified foreign financial assets and is filed with your Form 1040. FinCEN Form 114 – FBAR – covers foreign financial accounts and is filed separately through the FinCEN BSA e-Filing system, not with the IRS.
| Form 8938 | FinCEN Form 114 – FBAR | |
|---|---|---|
| Who files | Individuals and domestic entities with specified foreign assets | US persons with a financial interest in or authority over foreign financial accounts |
| Trigger | Foreign assets above the reporting threshold | Aggregate value of all foreign accounts exceeded $10,000 at any point in the year |
| Thresholds – living abroad | Single/MFS: over $200,000 year-end or $300,000 at any point; MFJ: over $400,000 year-end or $600,000 at any point | $10,000 aggregate across all accounts at any single point |
| What it covers | Stocks, trusts, ownership interests in foreign entities, foreign financial accounts | Bank, brokerage, pension, and insurance accounts at foreign financial institutions |
| Where to file | Attached to Form 1040 | FinCEN BSA e-Filing system – not the IRS |
| Due date | Same as Form 1040; automatic June 15 extension for expats | April 15, automatic extension to October 15 – no form required |
| Penalties | $10,000 for failure to file, plus up to $50,000 more for continued failure after IRS notice – up to $60,000 total; 40% accuracy penalty under IRC 6662(j) on related underpayments | Non-willful: up to $16,536 per report; willful: the greater of $165,353 or 50% of the account balance per 31 USC 5321 and 31 CFR 1010.821, unchanged for 2026 under OMB M-26-11 |
FBAR penalties apply per report, not per account – a rule the Supreme Court confirmed in Bittner v. United States in 2023.
For a detailed comparison, see our guide on FBAR vs Form 8938.
Forms 5471, 8865, 8621, and 8858: reporting businesses and investments abroad
Expatriate tax filing for foreign business and investment interests is where most expats fall short – each of these four forms targets a different ownership structure.
The table below maps each form to its trigger and penalty exposure.
| Form | What it covers | Common trigger | Initial penalty |
|---|---|---|---|
| Form 5471 | Foreign corporations | Ownership, control, or specified transactions | $10,000 per form, per year |
| Form 8865 | Foreign partnerships | Control, 10%+ ownership, acquisitions, transfers | $10,000 per form, per year |
| Form 8621 | PFICs – foreign mutual funds, ETFs | Direct or indirect interest in a PFIC | No flat penalty; adverse tax treatment applies |
| Form 8858 | Foreign disregarded entities and branches | Certain Form 5471 filers with FDEs; US persons with foreign branches | $10,000 per form, per year |
Form 5471: foreign corporations
Form 5471 is required for US persons who meet any of several filer categories, not only those who own more than 50% of a controlled foreign corporation.
Filing can also be required for certain 10% US shareholders, officers or directors when specified ownership changes occur, and persons acquiring or disposing of stock.
Who commonly misses it: Expats who set up a local company abroad – a UK Ltd, a German GmbH – without realizing the form attaches to their individual return.
Why it matters: Penalties start at $10,000 and rise by $10,000 every 30 days after IRS notice, up to $50,000 additional. Not filing keeps the statute of limitations for that year’s return open until three years after you furnish the missing form. Without reasonable cause, the entire return stays open – not just items related to the foreign corporation.
See our guides on Form 5471 and controlled foreign corporations for the full filer-category breakdown.
Form 8865: foreign partnerships
Form 8865 applies when a US person has specified control, 10% or greater ownership, or makes certain acquisitions, dispositions, or transfers involving a foreign partnership.
Schedules K-2 and K-3 may be required depending on the partnership’s international tax items.
They are not automatic with every Form 8865.
Who commonly misses it: Expats who enter a business partnership abroad and treat it like a domestic arrangement.
Why it matters: Penalties mirror Form 5471 – $10,000 per form, per year – with possible foreign tax credit reductions on top.
Form 8621: passive foreign investment companies – PFICs
Form 8621 may be required when a US person holds a direct or indirect interest in a PFIC, including many foreign mutual funds and ETFs.
The filing requirement can apply across a range of situations outlined in the IRS instructions, not only on distributions or sales.
Who commonly misses it: Expats who invest in local funds abroad – an ISA in the UK, a local index fund in Germany – without recognizing them as PFICs under US rules.
Why it matters: Form 8621 follows separate PFIC reporting rules. Missing a required filing can keep the assessment period open under IRC 6501 until the form is received. A QEF or mark-to-market election can reduce the tax burden, but limited late-election procedures may be available under specific IRS conditions – timing still matters.
See our PFIC tax guide and Form 8621 guide for election options and common PFIC examples.
Form 8858: foreign disregarded entities and branches
Form 8858 applies to certain Form 5471 filers with foreign disregarded entities or foreign branches, and to US persons operating foreign branches.
A foreign single-member entity must be classified as disregarded for US tax purposes to fall under this form – ownership alone does not universally trigger it. Freelancers with a separate set of books abroad may also have a foreign branch under the current IRS definition.
Why it matters: One of the least-known overseas tax forms in the expat filing system. Penalties start at $10,000 per entity per year.
See our guide on foreign disregarded entities and Form 8858 for trigger details and the Form 5471 connection.
See our foreign company tax reporting guide for a cross-reference of all entity forms and their filing requirements.
How to file US tax forms for expats
The 2026 filing season covers tax year 2025, and filing expat taxes from abroad follows the same core steps whether you owe a balance or expect a refund.
A return is still required even when FEIE or FTC eliminates all US liability. Under the rules governing taxation of American citizens living abroad, filing and payment are separate obligations – you can owe nothing and still need to file.
Step 1: Mark your exact 2026 deadlines
- April 15, 2026 – regular due date for tax year 2025 returns. Interest on unpaid tax begins on this date.
- June 15, 2026 – automatic two-month extension for qualifying taxpayers abroad. No form required. Covers both filing and payment without a failure-to-pay penalty, but interest accrues from April 15.
- October 15, 2026 – extended deadline with Form 4868, filed by June 15. Extends the filing date only – not payment.
- December 15, 2026 – discretionary additional extension by letter to the IRS, sent by October 15. Not automatic.
Step 2: Gather your documentation
Collect all records of foreign income – wages, self-employment income, foreign bank statements, and brokerage records. Decide which forms apply to your situation before you begin.
Step 3: Convert and classify
Use a posted exchange rate consistently, but follow the rule for each form and item – some amounts use the rate on the date received or paid, while others may allow an annual average. Sort income and taxes by category before calculating credits or exclusions.
Step 4: File and pay
You can file from abroad by e-file or mail and pay electronically from most banks. Verify addresses, bank details, and any FEIE or FTC schedules before submitting.
See our guide on US tax deadlines and extensions for the full 2026 filing calendar.
Common mistakes with expat tax forms
The most costly errors in expat filing are structural, not mathematical.
The most common structural error is assuming local income tax covers your US taxes while living abroad – the two systems are entirely independent.
The seven mistakes below are among the most common errors TFX sees each filing season.
- Assuming Form 1040 is the only form needed. Most expats need at least one additional form, and anyone with foreign accounts above $10,000 needs FBAR on top of that.
- Confusing FBAR with Form 8938. They cover different things, and filing one does not satisfy the other. Many expats need both.
- Treating FBAR as an IRS form. FinCEN Form 114 is filed through the FinCEN BSA e-Filing system – not attached to your return and not sent to the IRS.
- Assuming FEIE removes the need to file. Even if the exclusion eliminates all US tax owed, a return is still required when income meets the filing threshold.
- Missing foreign business and investment reporting. Forms 5471, 8865, and 8858 carry penalties starting at $10,000 per form, per year. Form 8621 follows separate PFIC rules and can keep the assessment period open indefinitely until the form is filed.
- Getting the deadline logic wrong. The June 15, 2026, extension covers both filing and payment without a failure-to-pay penalty for qualifying expats – but interest on unpaid tax runs from April 15, 2026.
- Forgetting that FBAR thresholds are aggregate. The $10,000 trigger applies to the combined value of all foreign accounts at any single point during the year – not the year-end balance of each account separately.
NOTE! Our IRS tax amnesty programs guide compares Streamlined filing with other catch-up options. If you have missed several years of expat forms, see whether IRS Streamlined procedures may apply to your situation.
See our guide on how to fix common FBAR mistakes for correction procedures and amended FBAR filing.
Penalties for missing expat tax forms
Each missed form can carry its own penalty even where no additional income tax is due. If you owe US taxes while living overseas, catching up sooner is almost always less expensive than waiting.
Timing and facts affect outcomes – penalties are not automatic in every case, and reasonable cause relief is available for some forms.
Penalty exposure by form:
| Form | Penalty risk | Why timing matters |
|---|---|---|
| FBAR – FinCEN 114 | Non-willful: up to $16,536 per report; willful: the greater of $165,353 or 50% of account balance | Voluntary filing before IRS contact strengthens the case for reduced or waived penalties |
| Form 8938 | $10,000 for failure to file, plus up to $50,000 more for continued failure after IRS notice – up to $60,000 total; 40% accuracy penalty on related underpayments | FATCA penalties apply even when no tax is owed on the underlying assets |
| Forms 5471, 8865, 8858 | $10,000 per form, per year; continuation penalties up to $50,000 additional after IRS notice | Not filing can keep the statute of limitations open for the entire return |
| Form 8621 | No flat per-form penalty, but adverse excess-distribution tax treatment applies | Missing the form can suspend the assessment period under section 6501(c)(8) |
| Form 1040 – late filing | Failure-to-file: 5% of unpaid tax per month, up to 25%; minimum penalty of $525 if filed more than 60 days late for returns due after 12/31/2025 | Filing stops the penalty from growing; the statute of limitations does not begin until you file |
If you discover missed filings:
- Gather records for the years in question – income statements, foreign account balances, entity documents
- Determine which forms are missing – income tax returns, FBARs, information returns, or all three
- Assess whether you qualify for Streamlined Foreign Offshore Procedures – 0% penalty for qualifying non-willful expats – or another compliance path
- File sooner rather than later – voluntary compliance before IRS contact consistently produces better outcomes

FAQs on tax forms for US citizens living abroad
Yes. The US taxation of citizens living abroad is based on worldwide income, so you must file a federal return when gross income meets the applicable threshold. The obligation follows citizenship, not location.
Most expats file Form 1040 as their base return, with Form 2555 or Form 1116 attached to address foreign income.
The standard US tax filing package for citizens living abroad adds an FBAR when foreign accounts exceed $10,000. Depending on assets and entity interests, you may also need Form 8938, Form 5471, Form 8865, or Form 8621.
Yes. Filing a tax return as an American citizen living abroad is required when income meets the threshold, even if exclusions bring the balance to zero. FEIE and FTC apply only if you file.
Yes. Taxes for Expats routinely prepares late and multi-year returns, including FBAR catch-up filings and Streamlined Foreign Offshore Procedures, with dedicated CPA support.
Yes – the obligation follows citizenship, not residence, and applies to worldwide income once your gross income meets the filing threshold. Credits and exclusions like FEIE and FTC can reduce or eliminate the amount owed, but you must file to claim them.
Start with Form 1040, then determine which additional forms apply based on your income, foreign accounts, and any entity ownership. Filing is required even when credits and exclusions reduce your US tax to zero.
If you meet both thresholds, yes – filing your US tax return while living abroad means submitting both. FBAR goes to FinCEN for foreign accounts; Form 8938 attaches to your Form 1040 for specified foreign assets. Filing one does not satisfy the other.
The federal rates and brackets stay the same regardless of country. For US citizens living abroad, the key taxation question is whether FEIE or FTC produces a better result – and that depends on the host country’s tax rate and any applicable treaty.
The tax forms to file for an overseas American start with Form 1040, then any credits or exclusions – Form 2555 or Form 1116. FBAR and Form 8938 are filed when their separate thresholds are met, and entity forms attach last.
