What an IRS Letter of Non-Filing Is and When You Need One
An IRS Letter of Non-Filing is an official document from the Internal Revenue Service stating that you did not file a federal income tax return for a specific year or years. The IRS issues this letter when you request it, and it serves as proof to third parties — typically lenders, landlords, or government agencies — that you had no filing requirement or chose not to file during that period.
You most commonly need this letter when applying for a mortgage, refinancing a home loan, or seeking rental assistance. Lenders want to verify your tax history before approving credit. Some government programs also request it to confirm your income status. The letter does not mean you owe taxes or that anything is wrong — it simply documents that no return was filed for the year you specify.
The letter is different from a tax transcript. A transcript shows what you reported on a return you actually filed. A non-filing letter proves you did not file at all. If you did file but want to show your income from that year, you would request a transcript instead.

How to Request the Letter by Mail
Requesting by mail is the most straightforward method and leaves a paper trail. Write a letter to the IRS that includes your full name, current mailing address, Social Security number, and the specific tax year or years for which you need the non-filing letter. State clearly in the letter that you are requesting a "Letter of Non-Filing" for those years.
Mail your request to the IRS office that serves your state. The address depends on where you live; you can find the correct address on the IRS website under "Where to File" or by calling the IRS at 1-800-829-1040. Include a self-addressed, stamped envelope if you want the response mailed back quickly. The IRS typically processes mail requests within two to four weeks.
Keep a copy of your request for your records. If you do not receive the letter within a month, you can follow up with the same IRS office or call to check the status.
Requesting the Letter by Phone or Online
You can also call the IRS directly at 1-800-829-1040 to request a Letter of Non-Filing. Have your Social Security number and the tax years you need ready. The IRS representative will take your information and can often mail the letter to you the same day. This method is faster if you need the letter urgently, though you will still wait one to two weeks for it to arrive by mail.
If you have an IRS online account (created through IRS.gov), you may be able to view and download certain tax documents directly, though the non-filing letter is not always available through this route. Check your account first; if the option is not there, use the phone or mail method.
What Information You Will Need to Provide
The IRS will ask for basic identifying information to process your request. Have the following ready: your full legal name (as it appears on your Social Security card), your Social Security number, your current mailing address, and the specific tax year or years for which you need the letter. If your address has changed since the year in question, provide both your old and current addresses.
If you are requesting the letter on behalf of someone else — for example, as a spouse or power of attorney — you may need to provide additional documentation proving your authority to request it. Ask the IRS representative or include a note with your mail request explaining the situation.
How Long the IRS Takes to Issue the Letter
Processing time depends on how you request it. Mail requests typically take two to four weeks from the date the IRS receives your letter. Phone requests are usually faster; the IRS can often process them within one to two weeks. During tax season (January through April), processing may take slightly longer due to higher volume.
If you need the letter for a specific deadline — such as a mortgage application closing date — mention this when you call or include it in your written request. The IRS cannot always expedite, but they will note the urgency. For time-sensitive situations, calling is your best option because you can speak to a representative immediately and confirm they have your correct mailing address.
Using the Letter for Mortgage and Rental Applications
Lenders and landlords ask for a Letter of Non-Filing to verify your income history and tax compliance. When you submit it, the letter serves as official proof that you had no filing requirement or did not file for the years specified. This is particularly common in mortgage underwriting when you have gaps in your tax history or are self-employed and want to show you were not required to file.
Some lenders may ask follow-up questions about why you did not file. Be prepared to explain: for example, you had no income that year, your income was below the filing threshold, or you were a dependent on someone else's return. The letter itself does not explain the reason, so you may need to provide additional context or documentation.
Keep the original letter or a certified copy with your application materials. If the lender or landlord requests it, you can also ask the IRS to send a copy directly to them, though this requires a separate request.
What to Do If You Are Unsure About Your Filing Status
If you are not certain whether you were required to file a return for a particular year, the IRS can clarify this when you request the letter. Mention your uncertainty in your request — either in your written letter or when you call — and explain your income situation for that year. The IRS representative can tell you whether filing was required and whether a non-filing letter is the right document for your situation.
Filing requirements depend on your age, income level, filing status, and type of income. For example, if you had no income or income below the standard deduction for your age and filing status, you likely had no requirement to file. If you received certain types of income — such as self-employment income over $400 — you may have been required to file even if your total income was low.
Frequently Asked Questions
Can I get a Letter of Non-Filing for multiple years at once?
Yes. When you request the letter, specify all the years you need it for. You can request it for consecutive years or individual years. The IRS will issue one letter that covers all the years you list, or separate letters for each year, depending on your request.
Is there a fee for a Letter of Non-Filing?
No, the letter is free. The IRS does not charge for non-filing letters, tax transcripts, or other official documents they issue to you. Be cautious of third-party websites that claim to charge a fee to obtain this letter; you can always request it directly from the IRS at no cost.
What if the IRS says I did file a return for that year?
If you requested a non-filing letter but the IRS records show you filed a return, they will tell you this. In that case, you will need a tax transcript instead, which shows what you reported on the return. You can request a transcript through the same methods — by mail, phone, or online account.
Can I request the letter if I owe back taxes?
Yes. Owing taxes does not prevent you from requesting a Letter of Non-Filing for years you did not file. The letter simply documents that no return was filed; it does not address whether you owe taxes. If you owe back taxes, you should address that separately with the IRS, but it will not stop you from getting the non-filing letter.
How long is the letter valid for?
The IRS does not put an expiration date on the letter. Once issued, it remains valid indefinitely as proof that you did not file for that year. However, lenders and other organizations may have their own policies about how old a document can be. If the letter is more than a year or two old, you may want to request a fresh copy to be safe.
