Important Notice: Tax Payment History May Affect Your U.S. Citizenship Application
Why unfiled returns and unpaid taxes matter on Form N-400, what the USCIS Policy Manual says, and what to check before you apply for citizenship.
The short answer
USCIS can find that a naturalization applicant lacks good moral character if the applicant did not file required tax returns or did not fully pay taxes during the statutory period. The USCIS Policy Manual lists this as an example of an unlawful act, and the officer decides case by case. Paying later does not automatically settle the question. An extension to file is not an extension to pay: the IRS says to pay tax owed by the April filing date.
At a glance
- Form N-400 applicants must show good moral character during the statutory period, which runs up to the Oath of Allegiance.
- The USCIS Policy Manual lists failure to file or pay taxes among the unlawful acts that can prevent a finding of good moral character.
- The officer decides each case. Some applicants can show that they corrected all errors, for example with a tax authority letter that the returns are filed and the taxes are paid or under a payment arrangement.
- An extension gives more time to file the return, not more time to pay the tax.
- USCIS may also look at conduct before the statutory period when it is relevant to present moral character (8 CFR 316.10(a)(2)).
What USCIS looks at
To naturalize, an applicant must show good moral character during the statutory period before filing Form N-400 and up to the Oath of Allegiance. The period for each applicant is explained in (page:g_lpr_to_citizen).
The USCIS Policy Manual (Volume 12, Part F, Chapter 5, Section L) says that an applicant who fails to file tax returns, if required to do so, or to fully pay the tax liability, as required under the relevant tax laws, may be precluded from establishing good moral character. Inconsistencies between the immigration record and the tax returns can have the same effect.
Paying later does not automatically settle it
The officer reviews each case. The Policy Manual says the officer decides whether the conduct violates the standards of an average member of the community, and whether there are extenuating circumstances.
Where the officer finds that the conduct did not violate those standards, or that there were extenuating circumstances, the applicant may establish good moral character by showing that all inconsistencies or errors are corrected. The Policy Manual gives as an example a letter from the tax authority stating that the applicant filed the required returns and paid the taxes, or made a payment arrangement and is following it.
Under 8 CFR 316.10(a)(2), USCIS is not limited to the statutory period. It may also consider earlier conduct when that conduct appears relevant to the applicant's present moral character.
An extension to file is not an extension to pay
The IRS says that an extension is only for filing the return, and that tax owed should be paid by the April filing date.
Before you file Form N-400
- Check every tax year in your statutory period: was a return required, was it filed, and was the tax fully paid?
- File any missing returns and pay any balance, or set up a payment arrangement with the tax authority and keep its letters.
- Make sure the answers on Form N-400 match your tax returns, for example your address, marital status and dependents.
- If a year was late, unpaid or under a payment plan, have an attorney review the record before you file.

Taxes and the citizenship application: questions people ask
can late tax payments affect my n-400 application
They can. The USCIS Policy Manual lists failure to file or fully pay taxes among the unlawful acts that may prevent a finding of good moral character. The officer decides case by case and considers extenuating circumstances.
if i paid my back taxes can i still be denied citizenship
Paying does not automatically settle the question. The officer first decides whether the conduct violates the standards of an average member of the community. Where it does not, or where there were extenuating circumstances, proof that all errors are corrected can help.
does a tax filing extension give me more time to pay
No. The IRS says the extension is only for filing the return. Tax owed should be paid by the April filing date.
can uscis look at tax years before the statutory period
Yes, in some cases. Under 8 CFR 316.10(a)(2), USCIS may consider earlier conduct when it appears relevant to present moral character. An attorney at Merit Law LLP can review your tax history before you file Form N-400.
