Frequently asked questions
Does the IRS accept fax for notice responses?
Yes — the IRS accepts fax responses for many CP notices, penalty abatement letters, and audit correspondence. The correct fax number is printed directly on your notice. Not all IRS offices accept fax for all document types — always use the fax number on your specific letter.
Where do I find the IRS fax number?
The fax number for your specific case is printed on your IRS notice or letter — usually in the top right corner or at the bottom of the response instructions. Do not use generic IRS fax numbers found online; they may be for different departments and your document could be misrouted.
Will FaxSeal's receipt prove I responded on time?
The timestamped delivery receipt shows your fax reached the IRS line at a specific date and time. Many IRS units treat the fax date as the response date for deadline purposes. However, IRS processing of your response is separate — keep the receipt and follow up if you don't receive an acknowledgment within 30 days.
What should I include on the cover page for the IRS?
Include your full legal name (or business name), TIN or EIN, the tax year(s) at issue, the notice number and date from your IRS letter, total page count including the cover, your callback phone number, and a one-line description of what you're sending.
Can I fax a CP2000 response?
Yes. CP2000 notices include a fax number in the response instructions. Fax your signed response letter, any supporting documentation (W-2s, 1099s, receipts), and the agreement/disagreement section of the notice. Always include the cover page with your SSN and notice number.
Can I fax a penalty abatement request?
Yes. First-time penalty abatement (FTA) requests and reasonable cause letters are routinely faxed to the IRS. Use the fax number on the penalty notice or call the number on the notice to confirm the fax number for your specific Accounts Management unit.
What if the IRS fax line is busy or the fax fails?
If delivery fails, your card is never charged. You can retry immediately. IRS fax lines can be busy during tax season — if a deadline is imminent, also send your response by certified mail as a backup.
Do I need an account to fax the IRS?
No account required. Upload your PDF, enter the IRS fax number from your notice, pay from $1.29, and send. Enter your email at checkout to receive the delivery receipt.
