Frequently Asked Questions about Sample Letter Explaining Not Filing Taxes

Will this letter stop IRS penalties?

This letter will not automatically remove penalties, but it greatly improves your chance of getting penalties waived. Tax agents are far more likely to work with you if you communicate honestly and promptly.

Do I need a lawyer to send this letter?

You do not need a lawyer for most simple, honest situations. For cases involving multiple unfiled years or large tax debts, you may wish to consult a tax professional.

How should I send this letter to the IRS?

Always send this letter via certified mail with return receipt requested. This creates official proof that the IRS received your correspondence.

Can I send this letter by email?

The IRS does not accept formal explanation letters via standard email. You may submit it through the official IRS secure messaging portal if you have an active account.

How long does the IRS take to respond?

You will typically receive a written response from the IRS within 30 to 60 days. Do not send duplicate letters during this time unless you receive a follow up notice.

What if I owe money for the unfiled year?

Include a clear payment plan proposal in your letter. Even offering small monthly payments shows good faith and will prevent aggressive collection actions.

Can I use the same letter for multiple tax years?

You can explain multiple unfiled years in one letter, but list each year clearly separately. Always confirm your explanation applies to every year listed.

Should I admit I forgot to file?

Be honest. Simply state you failed to file, explain the reason briefly, and state your plan to fix the issue. Avoid emotional language or unnecessary excuses.

What happens if I never send this letter?

Ignoring unfiled tax notices will result in automatic penalties, wage garnishment, or bank levies. Even a short honest letter is always better than no response at all.
