Home > Guides > Faxing a 1099 form
Yes, you can fax a 1099 form to a recipient or a payer in many situations, but faxing is not the right route for every copy, and tax agencies have their own filing rules. Check which copy the recipient needs, confirm the fax number first, and keep the confirmation page with your records.
A 1099 form is not one document. It is a set of copies that go to different places: one copy to the person who was paid, one copy to the tax agency, and one copy kept by the payer. The rules for each copy are different, and that is where most faxing mistakes happen. A recipient copy sent by fax to the person who earned the income is a different act from a filing copy sent to the IRS or the Canada Revenue Agency, and the agencies have their own approved filing channels.
Start by naming the copy. If a contractor lost their copy and asks you to resend it, faxing a recipient copy is usually fine, and it is fast. If you are trying to file with the agency, stop and check the agency's current filing route first. In the US, the IRS generally wants 1099 filings through its electronic filing system or on paper forms it can scan, and a fax is not a standard filing method for most 1099 series forms. In Canada, T4A and T5 slips, the rough equivalents for many kinds of payments, are filed through CRA online services or on paper, not by fax as a rule.
| Copy | Goes to | Fax a sensible route? |
|---|---|---|
| Recipient copy (Copy B in the US) | The person or business paid | Often yes, if they agree to receive it that way |
| Payer file copy | Your own records | Faxing to yourself is pointless; keep the original file |
| Agency filing copy | IRS or CRA | Usually no; use the agency's filing channel |
| State or provincial copy | State or provincial tax office | Check that office's rules; many want electronic filing |
First, confirm the recipient wants it by fax. A 1099 carries a taxpayer identification number, and that number is exactly the kind of detail that should not travel to a wrong number. Call or email the recipient, confirm the fax number digit by digit, and ask them to confirm receipt. If the number belongs to a shared office fax, ask whether a private machine or a direct line is available, and whether someone will collect the pages right away.
Second, send only the pages the recipient needs. A full 1099 set includes instruction pages and copies meant for other parties. Sending the whole set by fax risks handing a shared fax tray pages that were never meant for that reader. Send the recipient copy and a short cover note with your name, the tax year, and a callback number. Leave off anything else.
Third, think about legibility. 1099 forms are dense, with small boxes and small print. A faint copy can turn a nine into a four, and on a tax form that kind of error costs the recipient real time. If the form is a photocopy of a photocopy, print a fresh copy from your filing software instead. After sending, ask the recipient to check the taxpayer identification number and the amounts against what they expect, and keep your confirmation page with the tax-year file.
Some IRS units do publish fax numbers for specific correspondence, such as responding to a notice or sending documents an examiner asked for. That is different from filing the form itself. If a notice tells you to fax documents to a named unit, follow the notice: it will give the number, the pages wanted, and often a case number to put on the cover sheet. The same logic holds in Canada, where the CRA may ask for documents by fax in a specific case, even though routine slip filing goes through its online or paper channels.
The trap is assuming that because one IRS fax number exists, any 1099 can be filed by fax. It cannot. A faxed filing copy that the agency never logged as a filing leaves you exposed to a late-filing penalty while believing you filed on time. If you are unsure which route a copy takes, check the form instructions for that tax year before you send anything. The instructions state the filing methods, and they change from year to year.
Never fax a 1099 to a number you found in a search result without verifying it belongs to the intended recipient. Numbers change hands, and old listings linger online for years. Use the number on the recipient's own letterhead, their invoice, or a number they confirm directly. If the recipient is an individual working from home, ask whether they have a private fax line or an online fax inbox rather than a shared machine. And once the fax is confirmed, do not leave your copy of the confirmation page in a shared tray: file it with the rest of the tax-year paperwork.
LetterAgent faxing is available in testing for US and Canadian numbers, with a per-fax quote you approve before sending. It cannot file a form with a tax agency on your behalf, and it cannot tell you which copy a given situation requires; the form instructions for that tax year are the authority.
