When you apply for U.S. citizenship, you are going to be asked about your history of paying taxes in the United States, as is required for nearly all income earners annually. Specifically, on the N-400 Application for Naturalization, U.S. Citizenship and Immigration Services (USCIS) will ask:
- “Do you owe any overdue federal, state, or local taxes?”
- “Have you ever not filed a federal, state, or local tax return since you became a lawful permanent resident?,” and
- if you didn’t file, “Did you consider yourself to be a non-U.S. resident?.”
Here's what to do if the answer to any of those indicates that you didn't pay taxes as was legally required.
How Paying Taxes Fits Into the Good Moral Character Requirement for U.S. Citizenship
USCIS asks these various tax questions as part of its test of your moral character, one of the eligibility requirements for naturalization in the United States. You must prove to USCIS that you have been a person of good moral character during at least the five years before you file your N-400; or three years if you will be filing under the rule that allows spouses of U.S. citizens to apply after three years of permanent residence.
Anyone who has committed an “unlawful act” during the relevant period (or even before) can be found to lack good moral character. Failure to file a tax return or pay taxes owed is considered to be an unlawful act, whether you were convicted of a crime because of it or not.
There are also actual crimes related to tax filing, such as "tax evasion." Under U.S. immigration law, committing tax evasion in which the revenue loss to the government is over $10,000 will be viewed as an "aggravated felony," and grounds for deportation. Applying for U.S. citizenship will not help you in such a situation, and could in fact hasten your deportation by bringing your file to the attention of the U.S. government. (See the law at I.N.A. 1101(a)(43)(M), 8 U.S.C. 1101(a).)
How USCIS Will Evaluate Whether You Complied With U.S. Tax Laws
At the citizenship interview that is the culmination of your application process, a USCIS officer might ask to see copies of your tax returns, or a tax transcript, for the past five (or three) years to verify that you did file as was required. You will want to be ready for this, and to take action if you failed to file, as described next.
Also be aware that USCIS will look carefully at the tax returns you submitted. It might spot issues to rouse its suspicions; perhaps differences in facts submitted on your N-400 and those on your tax return, such as marital status, number of children, and employment. It could then decide that you were trying to defraud the IRS or state or local government by avoiding taxes—even if the relevant government agency accepted your return without a problem.
Don’t try to avoid this problem by giving false information on your N-400 to match what was on a tax return. That’s a guaranteed way to have your U.S. citizenship application denied. Instead, consult a tax attorney first to deal with any issues.
How to Handle Past Failure to File U.S. Income Taxes
If your true answer is “yes” to any of the tax-related questions on the Form N-400, you should, before sending it in, consider whether it makes sense to apply now versus after more years have passed. If you think you can still prove good moral character or provide a justification for the failure to file, attach a sheet explaining why you answered “yes.”
A “yes” answer to the question about whether you have ever not filed a tax return isn’t going to be a problem if you weren’t required to file a tax return that year, perhaps because your income was below the minimum required for filing. (You should verify your belief that you were not required to file a tax return with a tax specialist before applying for U.S. citizenship.)
It also won’t be a problem if you filed the tax return late, before applying for citizenship.
In the past, a “yes” answer to the overdue taxes question wasn’t necessarily a problem if the applicant could show that they were in compliance with an ongoing repayment program (including providing a signed repayment agreement from the relevant federal, state, or local tax office and documentation showing the current status of their repayments). However, USCIS has, per the language of an August 2025 USCIS memo, expressed plans to not only require more affirmative evidence of GMC going forward, but to "focus greater attention on ensuring that aliens who have engaged in wrongdoing are properly rehabilitated and reformed," including by "full payment of overdue taxes." Thus, a partial repayment of taxes and a plan to continue on schedule going forward will no longer be sufficient. You will want to complete this process, and provide proof of full repayment from the IRS, before submitting your citizenship application.
If you didn’t file a tax return because you considered yourself to be a non-U.S. resident, that’s going to be a problem. As a lawful permanent resident, you were supposed to be residing in the United States, so you could end up "solving" one ineligibility problem but creating another.
Other Extenuating Circumstances Can Excuse Failure to File U.S. Taxes
Even if USCIS finds that you have committed an unlawful tax-related act, it can still find that you have good moral character if you failed to file a return or pay taxes because of “extenuating circumstances.”
This means something out of the ordinary that prevented you from complying with the law. For tax problems this is rare. One example might be a situation where you could not make a payment on overdue taxes because of emergency medical bills. Make sure you explain any extenuating circumstances on your supplement sheet to the N-400 and provide documents from official sources (such as doctors or hospital billing departments) to back it up.
Another example might be your failure to understand a highly technical part of U.S. tax law. (This assumes you yourself are not a tax pro.)
Getting Legal Help
Given the complexities of explaining tax matters to U.S. immigration authorities, you could make your life easier by hiring an experienced immigration attorney to handle your naturalization case. The attorney can perform the following sorts of helpful tasks:
- analyze the facts
- strategize regarding when it would be worth you submitting an application
- prepare the N-400 and other paperwork, explain what documents you'll need to gather
- draft compelling arguments summarizing the situation for USCIS, and
- monitor the progress toward approval.
