Digital Nomad Tax Guide

Tax home is the place where your principal business or work is located (not necessarily where you reside). IRS defines tax home based on: (1) place of regular business, (2) where you spend most of your time, (3) where family is located. If you are a nomad with no permanent residence, your tax home is where your principal work is performed. If you have multiple locations, the IRS looks to where you spent most days working. Tax home determines: whether you can claim FEIE (Foreign Earned Income Exclusion), state residency for tax purposes, and filing status.

Yes, if you meet the physical presence test: outside the U.S. for 330 days in any 12-month period. FEIE allows excluding $132,900 (2026) of foreign earned income. Example: travel to 12 countries throughout year, 330+ days outside U.S., earn $100k from online clients. FEIE: exclude $100k, pay $0 federal income tax (on that income). Must track days carefully (passport stamps, airline tickets, hotel records). Penalty for false FEIE claim: 20% accuracy penalty + interest.

Physical presence test requires 330 days outside the U.S. in a 12-consecutive-month period. Days count as follows: departure day = outside U.S. (counts toward 330); arrival day = outside U.S. (counts toward 330). All days in a foreign country count (regardless of partial day). Days in U.S. = not counted (subtract from 330). Example: January 1 leave U.S. to January 15 return U.S. = 14 days outside (Jan 1-14). If you make day trips to U.S., each day counts as presence (negates FEIE for that day).

Yes, if you maintain residency in a tax state. Many states deem you a resident if you own a home, have business presence, or claim domicile there. While traveling, if you still have residency in California (for example), California may tax your worldwide income. Solution: establish residency in a no-income-tax state (Florida, Nevada, Texas, Wyoming, Washington, Tennessee, South Dakota) or clearly break residency in tax state (sell home, change address, update voter registration). Some states use physical presence tests (spend 183+ days = resident), others use intent tests.

Tax treaties between U.S. and other countries may provide reduced tax rates, FEIE alternatives, or social security benefits. Example: U.S.-Mexico treaty provides FEIE alternative (excludes income earned in Mexico under treaty, not IRC 911). Some treaties provide reduced withholding on royalties/interest (if you earn passive income from other countries). Treaty benefits vary; consult treaty summary for countries where you work. File Form 8833 if claiming treaty position different from tax code.

Report all worldwide income on Form 1040: U.S. earned income (W-2), foreign earned income (Schedule C if self-employed), investment income (interest, dividends, capital gains). If using FEIE, claim on Form 2555 and exclude eligible income. Report each country's income separately on Schedule C (line by country is not required, but helpful for record-keeping). File Form 1040 by April 15 (June 15 extension for expats). Report foreign bank accounts on FBAR (Form 114) if $10k+.

Foreign Tax Credit (FTC, Form 1116) is a credit for taxes paid to other countries. Cannot use FEIE + FTC on same income; choose one. FEIE better if: low-tax country (15-20%), income under $132.9k. FTC better if: high-tax country (40%+), high income (over $132.9k). Example: earn $150k in high-tax country (40% tax). FEIE: exclude $132.9k, pay U.S. tax on $17.1k = ~$6.3k. FTC: pay 40% foreign ($60k) + 37% U.S. (limited), claim credit. Compare both; use whichever saves more tax.

Self-employment (SE) tax (~15.3% on net self-employment income) applies to foreign earned income. FEIE excludes income tax, NOT SE tax. Example: $100k self-employment income from foreign clients. FEIE: exclude $100k from income tax. SE tax: 15.3% × $100k = $15.3k still owed. Some countries have totalization agreements (avoid double SS tax). If you are in a non-totalization country, you owe U.S. SE tax on foreign income.

FBAR (Form 114): required if foreign accounts total $10k+. File with FinCEN by April 15. FATCA (Form 8938): required if foreign assets exceed $600k (single, living abroad) or $1.2M (married, living abroad). File with Form 1040. Both apply if thresholds met. Example: travel through Europe, maintain foreign bank account for expenses ($25k balance). File FBAR (over $10k). If assets exceed $600k, file Form 8938. Penalty for non-filing: 50% of account balance (FBAR) or 5% per month (FATCA).

Proof of foreign residence required if IRS challenges FEIE claim: passport stamps showing departure/return, airline/hotel receipts, employment contract, lease agreement, foreign utility bills, bank statements. Keep detailed records: calendar of travel (dates by country), boarding passes, hotel confirmations. IRS may request substantiation if audited (especially if claiming FEIE for multiple years). Failure to substantiate = loss of FEIE and back taxes + penalties.

Maintain U.S. bank account for tax documentation (U.S. address on file). Open foreign accounts as needed for local expenses (withdraw cash, pay vendors). Report all accounts on FBAR. Use international bank transfers (wise, remitly) for funding foreign accounts (cheaper than wire transfers). Get U.S. business mailing address (virtual mailbox service like iPostal1) for receiving documents (tax forms, bank statements). Keep all financial records for 7 years (IRS audit period). Report foreign account interest/dividends on Form 1040 (line 7-8).
