What is required for tax filing?
Answer
You must have filed taxes for required years
Explanation
Applicants for naturalization must show that they have filed federal tax returns for every year of the statutory residence period (the past five years for most applicants under section 316, or the past three years for spouses of U.S. citizens under section 319) in which they were required to file. The tax-filing requirement is part of the good moral character standard under section 316(a)(3) of the Immigration and Nationality Act (8 U.S.C. section 1427(a)(3)) and 8 CFR section 316.10, which provides that an applicant who has willfully failed or refused to file federal tax returns may be found to lack good moral character and have the application denied.
USCIS does not require applicants to have paid all taxes owed in full, but applicants who owe back taxes must demonstrate that they have entered into and are complying with a written installment payment agreement with the Internal Revenue Service (IRS Form 9465 is the standard installment agreement request) or equivalent state tax authorities. Applicants who failed to file in any year because their income was below the IRS filing threshold for that year (no tax liability and no filing requirement) do not need to demonstrate filing for those years; they should bring evidence of the income level that exempted them from filing.
Applicants who lived abroad during the five-year period and were exempt from U.S. filing or claimed the foreign earned income exclusion under section 911 of the Internal Revenue Code (Form 2555) bring documentation of that. Applicants who did not file when required, but whose failure was inadvertent rather than willful, can mitigate the issue by filing the missing returns before the interview and bringing copies plus IRS account transcripts showing the filings have been received.
The interview officer asks the applicant about tax filing during the good moral character review and may request copies of federal tax returns or IRS account transcripts (free at irs.gov/transcripts) for each year of the statutory period. Applicants who filed jointly with a spouse should bring the joint returns even if the citizen spouse paid all of the tax. Applicants with significant unfiled returns or unpaid taxes should consult a tax attorney or accountant before filing N-400 to avoid risking denial.
Why this matters for your test
Tax compliance is a frequent issue at the interview and a common reason for denial when not handled in advance. Bringing IRS transcripts for the full statutory period and documentation of any installment agreement is a simple way to demonstrate compliance and avoid surprises during the good moral character review.
