The L2 visa carries no federal tax exemption of its own. Whether you owe US tax, and how much, depends on how the IRS classifies you (resident alien or nonresident alien) and whether a tax treaty between the US and your home country reduces the rate on specific types of income. Most L2 spouses who live in the US full-time cross the residency threshold within their first or second calendar year and end up taxed on their worldwide income, the same way a US citizen is.
Why Your Visa Does Not Determine Your Tax
Immigration status and tax status run on separate tracks. The IRS uses its own rules under Internal Revenue Code Section 7701(b) to sort every foreign national into resident alien or nonresident alien.1Internal Revenue Service. Introduction to Residency Under US Tax Law That classification, not the L2 stamp in your passport, decides which income gets taxed, which form you file, and which deductions and credits you can claim.
The primary test is the Substantial Presence Test. You count as a resident alien if you were physically in the US for at least 31 days during the current year and your weighted day count reaches 183 or more. The weighted count adds all days in the current year, one-third of the days in the prior year, and one-sixth of the days two years back. An L2 spouse who arrives and stays continuously usually hits 183 weighted days in the first calendar year or early in the second.
Once classified as a resident alien, you file Form 1040 and report income from every source worldwide. If you remain a nonresident alien, you owe US tax only on income connected to a US trade or business and on certain US-sourced passive income like dividends, and you file Form 1040-NR.2Internal Revenue Service. Alien Taxation – Certain Essential Concepts
The Closer Connection Exception
If you meet the Substantial Presence Test but spent fewer than 183 days in the US during the current tax year, you may be able to claim the Closer Connection Exception and keep nonresident status. You have to show a tax home in your foreign country for the entire year and stronger personal and economic ties to that country than to the US, based on things like where your permanent home, family, belongings, and social connections sit. You cannot have applied for or taken steps toward a green card. The claim is made on Form 8840.3Internal Revenue Service. Closer Connection Exception to the Substantial Presence Test – Section: How to Claim the Closer Connection Exception
In practice, this exception is hard for L2 spouses to use. The whole point of the visa is to live with a spouse who works in the US, which undercuts any argument that your stronger ties are elsewhere.
Where Actual Tax Breaks Come From: Treaties
The US has income tax treaties with dozens of countries, and these treaties are where genuine reductions in US tax usually live for L2 holders.4Internal Revenue Service. Tax Treaty Tables To claim a benefit, you must be a resident of the treaty partner country as that specific treaty defines residence. You disclose the treaty position on Form 8833, attached to your tax return.5Internal Revenue Service. About Form 8833, Treaty-Based Return Position Disclosure Under Section 6114 or 7701(b) Skipping Form 8833 when you rely on a treaty can trigger a $1,000 penalty.6Internal Revenue Service. Form 8833 – Treaty-Based Return Position Disclosure Under Section 6114 or 7701(b)
Treaty relief most commonly applies to passive income that is not connected to a US business: dividends, interest, pensions, royalties, and annuities. The default US withholding rate on these payments to nonresident aliens is 30%, but many treaties cut that to 15%, 10%, or zero depending on the income type and the country.7Internal Revenue Service. Table 1 – Tax Rates on Income Other Than Personal Service Income Under Chapter 3, Internal Revenue Code, and Income Tax Treaties Some treaties also temporarily exempt certain personal-services compensation.
The Savings Clause Catch
Nearly every US tax treaty contains a savings clause that preserves the US right to tax its own residents as if the treaty did not exist. Once you become a resident alien under the Substantial Presence Test or by election, the savings clause generally blocks you from claiming treaty benefits on your US-sourced income.8Internal Revenue Service. Claiming Tax Treaty Benefits Some treaties carve out exceptions for specific categories like pensions, social security, or certain student and trainee income, but whether your treaty has a useful carve-out depends on its exact text.
This is the central tension in L2 tax planning. Treaty benefits are strongest when you are still a nonresident alien. The longer you live in the US, the more the savings clause narrows what treaty protection can actually do for you.
Breaks Available Only to Nonresident Aliens
Nonresident alien status carries a few genuinely favorable rules on investment income. Interest earned on US bank deposits is exempt from US tax entirely.9Office of the Law Revision Counsel. 26 US Code 871 – Tax on Nonresident Alien Individuals Capital gains from selling US stocks or mutual funds are generally not taxable for an NRA present in the US for fewer than 183 days during the year. US-sourced dividends are still subject to the 30% withholding tax unless a treaty reduces it.
These NRA-only breaks disappear the moment you become a resident alien, whether by the Substantial Presence Test or by election. Working the other direction, resident aliens get the standard deduction; nonresident aliens do not.10Internal Revenue Service. Nonresident – Figuring Your Tax For an L2 spouse with modest US wages and no significant itemized deductions, losing the standard deduction can more than offset any NRA advantages on investment income.
Foreign Earned Income Exclusion: Usually Not Available
The Foreign Earned Income Exclusion lets qualifying taxpayers exclude up to $132,900 of foreign earned income in 2026,11Internal Revenue Service. Figuring the Foreign Earned Income Exclusion but you need a tax home in a foreign country and either 330 full days abroad in a 12-month period or bona fide residence abroad for an entire tax year.12Internal Revenue Service. Foreign Earned Income Exclusion The L2 visa exists to keep you with a spouse working in the US, so most L2 holders cannot satisfy either test. Worth knowing about, rarely usable.
The Joint Filing Election and What It Costs
For L2 spouses who have not yet met the Substantial Presence Test, the biggest first-year decision is whether to make the Section 6013(g) election. This treats a nonresident alien spouse as a US resident for the entire tax year so both spouses can file a joint return.13eCFR. 26 CFR 1.6013-6 – Election to Treat Nonresident Alien Individual as Resident of the United States The election is made by attaching a signed statement to a joint Form 1040 that includes both spouses’ names, addresses, and taxpayer identification numbers.
Once made, the election stays in force for every future tax year unless revoked, or unless the couple divorces or separates. It cannot be made again between the same two spouses once revoked.13eCFR. 26 CFR 1.6013-6 – Election to Treat Nonresident Alien Individual as Resident of the United States The consequences are significant: both spouses become taxable on worldwide income, and the L2 spouse gives up the ability to claim treaty benefits as a foreign resident while the election is in force.
Joint filing usually produces a lower combined tax bill because of wider brackets and access to the standard deduction. But if the L2 spouse has substantial foreign income that would otherwise get favorable treaty treatment, the election can cost more than it saves. Run the numbers both ways before committing, because the door only opens once.
If the L2 spouse has no Social Security Number, they need an Individual Taxpayer Identification Number to file jointly. Apply on Form W-7, typically attached to the front of the return.14Internal Revenue Service. Instructions for Form W-7 Using an IRS-authorized Certified Acceptance Agent avoids mailing your original passport.
What L2 Holders Are Not Exempt From
Once you become a resident alien, several obligations kick in that L2 holders sometimes assume the visa shields them from. It does not.
Social Security and Medicare Taxes
F-1, J-1, and Q-1 holders get a temporary FICA exemption during their initial period in the US. L2 holders do not. As a resident alien working in the US, your wages are immediately subject to FICA at the standard 7.65% employee rate: 6.2% for Social Security and 1.45% for Medicare.15Internal Revenue Service. Aliens Employed in the US – Social Security Taxes Your employer pays a matching 7.65%. The Social Security portion applies only to wages up to $184,500 in 2026; Medicare has no cap.16Social Security Administration. Contribution and Benefit Base L2 spouses are authorized to work in the US without a separate employment authorization document, though many still obtain an EAD as proof.17U.S. Citizenship and Immigration Services. Handbook for Employers M-274 – 7.9.2 L Nonimmigrant Status – Section: Dependent Spouse of L-1A and L-1B Workers
Worldwide Income Reporting
Resident alien status means reporting income from every source: foreign employment, rental properties, investment accounts back home. The Foreign Tax Credit on Form 1116 offsets taxes you already paid to another country on the same income,18Internal Revenue Service. Foreign Tax Credit which prevents double taxation on the same dollar even if it does not always eliminate US tax entirely.
FBAR: Foreign Account Reporting
If the combined value of all your foreign financial accounts exceeds $10,000 at any point during the year, you must file FinCEN Form 114 (the FBAR) electronically with the Financial Crimes Enforcement Network.19Financial Crimes Enforcement Network. Report Foreign Bank and Financial Accounts – Section: Who Must File the FBAR It is separate from your tax return, due April 15 with an automatic extension to October 15.20Financial Crimes Enforcement Network. Due Date for FBARs
The $10,000 threshold is aggregate. A savings account, a checking account, and a fixed deposit in your home country that together crossed $10,000 on a single day create a filing obligation. Non-willful violations carry a statutory baseline penalty of $10,000 per report, adjusted for inflation. Willful violations carry penalties of the greater of $100,000 or 50% of the account balance at the time of the violation.21Office of the Law Revision Counsel. 31 US Code 5321 – Civil Penalties After the Supreme Court’s 2023 decision in Bittner v. United States, the non-willful penalty applies per annual report rather than per account.
Form 8938: FATCA Reporting
Separately from the FBAR, FATCA requires reporting specified foreign financial assets on Form 8938, attached to your Form 1040. The thresholds depend on filing status:22Internal Revenue Service. Do I Need to File Form 8938, Statement of Specified Foreign Financial Assets
- Married filing jointly and living in the US: total value above $100,000 on the last day of the tax year, or $150,000 at any point during the year.
- Single or married filing separately and living in the US: total value above $50,000 on the last day of the tax year, or $75,000 at any point during the year.
Higher thresholds apply if you live outside the US, which is uncommon for L2 holders.
Mistakes That Turn Assumed Exemptions Into Bills
The most expensive errors are sins of omission. Missing the FBAR because you did not realize your home-country accounts crossed $10,000 is the single most common problem for L2 holders, and the penalties are wildly out of proportion to the effort of filing. Missing Form 8938 is a close second.
The next category is the 6013(g) decision. Filing jointly usually lowers the combined tax, but if the L2 spouse has significant foreign income that would benefit from treaty protection, the election can cost more than the joint filing saves. The election is permanent between the same two spouses once revoked, so it deserves a careful comparison before it goes on the return.
Finally, employers occasionally misclassify visa holders for FICA or apply incorrect withholding. Checking your pay stubs and W-2 against your actual residency status catches problems early rather than at filing time.
