When Your 1099 Forms Must Be Sent and Filed

1099 forms must reach you by January 31 each year, and you must file them with your tax return by the April 15 important date

The 1099 important date has two parts: the payer sends it to you by January 31, and you report the income on your tax return by April 15 (or October 15 if you file an extension). Missing either important date creates problems — the IRS tracks 1099s electronically, so if you don't report income that a payer reported, the IRS will notice and send you a bill for the missing tax plus penalties.

The January 31 important date applies to almost all 1099 types: 1099-NEC (nonemployee compensation), 1099-MISC (miscellaneous income), 1099-INT (interest), 1099-DIV (dividends), 1099-K (payment card transactions), and others. A few forms like 1099-B (brokerage transactions) have different dates, but January 31 covers the vast majority of 1099s you'll receive.

If you don't receive a 1099 by early February, contact the payer directly — they have your address on file and may have sent it to an old one. If the payer says they never issued one, ask them to file a corrected 1099 with the IRS. You can still file your tax return without it, but you must report the income you received regardless of whether you have the form.

Key Takeaways

• Payers must send you a 1099 by January 31 each year for any nonemployee income you earned the previous year.
• You must report all 1099 income on your tax return filed by April 15, even if you never received the form from the payer.
• The IRS receives copies of all 1099s electronically, so unreported 1099 income triggers an automated notice and tax bill.
• If a payer misses the January 31 important date or sends it to the wrong address, contact them directly to request a corrected form or updated mailing address.
• An extension to file your tax return (October 15) does not extend the January 31 important date for payers to send you 1099s.

What happens if you don't receive a 1099 by late January

Wait until early February before taking action — mail can arrive late, and some payers send forms in batches. If nothing arrives by February 5 or 6, call or email the payer's accounting or payroll department. Have your Social Security number or tax ID ready, and ask them to confirm they have your correct mailing address on file.

If the payer says they mailed it, ask them to send a duplicate copy by email or overnight mail. If they say they never issued one, ask them to file a corrected 1099 with the IRS and send you a copy. Either way, get the request in writing — an email counts — so you have proof you asked for it.

Do not delay filing your tax return waiting for a 1099. You can file without it and report the income based on your own records — a bank deposit, a check, a payment app record, or an invoice you sent. The IRS will eventually match the 1099 the payer files with your return, and if the amounts don't match, they'll send you a notice. Having filed on time with the correct income amount protects you in that conversation.

Why the IRS cares about 1099 important date

The IRS receives 1099s electronically from payers at the same time they send them to you. The agency's computer system automatically compares the 1099 income reported to your Social Security number against the income you report on your tax return. If you report less than the 1099 shows, the IRS generates a notice called a CP2000 (Correspondence Item 2000) proposing additional tax, interest, and penalties.

This notice arrives weeks or months after you file, and you have 30 days to respond. You can agree, disagree, or provide documentation showing the 1099 was wrong — for example, if a 1099-NEC included a payment you returned or a refund you received. The sooner you file with the correct amount, the less likely you'll receive this notice.

The January 31 important date for payers exists partly to give the IRS time to process millions of 1099s before the April 15 tax important date. If payers could send 1099s in April, the IRS wouldn't have time to match them against returns before issuing refunds, which would create fraud risk.

Different 1099 types and their January 31 important date

Most 1099 forms follow the January 31 rule, but a few have different dates. The most common exception is 1099-B (brokerage and mutual fund transactions), which is due February 15. 1099-R (retirement distributions) is also due January 31, as is 1099-Q (education savings account distributions).

For your purposes, assume January 31 unless you know otherwise. If you're self-employed and issue 1099s to contractors, you must send them by January 31 as well. If you receive a 1099 after January 31, it's late — contact the payer and ask why. Late 1099s sometimes indicate the payer is disorganized or has your information wrong, which can lead to other filing problems down the road.

What to do if a 1099 shows the wrong amount

If the 1099 amount doesn't match what you actually received, contact the payer when ready and ask for a corrected 1099. Payers can issue corrected forms (marked "CORRECTED" on the document) up until March 31. Ask the payer to file the corrected version with the IRS and send you a copy.

If the payer refuses to correct it or you can't reach them, file your return with the correct income based on your own records. When you file, keep documentation handy — bank statements, invoices, payment app records — that show what you actually earned. If the IRS later sends you a CP2000 notice, you can respond with this documentation and explain the discrepancy.

Common reasons for wrong amounts: the payer included a refund or returned payment they shouldn't have, they double-counted a payment, or they issued a 1099 for work you didn't actually do. None of these are your fault, but you still need to report the correct amount on your return.

Filing your return before you receive all your 1099s

You don't have to wait for every 1099 to arrive before filing. If you've received most of them by mid-February and one is missing, you can file with the income you have documented and amend your return later if needed. The IRS prefers you file on time with correct information rather than file late waiting for a missing form.

If you file before receiving a 1099 and later discover you missed income, you can file an amended return (Form 1040-X) within three years. The amended return is free to file, but it may trigger an audit or a CP2000 notice if the IRS has already processed your original return. Filing with all known income the first time avoids this hassle.

If you're self-employed or have multiple income sources, create a checklist in January of all the 1099s you expect. Track which ones have arrived and follow up on missing ones by mid-February. This takes an hour and prevents scrambling in April.

State and local 1099 reporting

Some states require you to report 1099 income on state tax returns as well. The state important date is usually the same as the federal important date — April 15 — but some states have different rules. A few states don't tax nonemployee income at all, so you'd report it only to the federal IRS.

Check your state's tax agency website or ask a tax preparer whether your state requires 1099 reporting. If you move during the year, you may owe tax to two states, and each may have different 1099 rules. This is one area where a tax professional can save you money and headache.

Frequently Asked Questions

What if I file my return before January 31 and later receive a 1099?

You must file an amended return (Form 1040-X) to report the additional income. The amended return is free and can be filed online or by mail. File it as soon as you receive the late 1099 to minimize interest and penalties.

Can I file an extension and get more time to receive 1099s?

No. Filing an extension (Form 4868) extends your important date to file your return to October 15, but payers still must send 1099s by January 31. An extension gives you more time to gather documents and prepare your return, not more time to receive forms from payers.

Do I need to attach 1099s to my tax return when I file?

No. You report the income on the appropriate line of your return (Schedule C for self-employment, Schedule 1 for other income), but you don't mail the 1099 itself with your return. Keep it with your records in case the IRS asks for proof later.

What if a payer issued a 1099 but I never actually received the money?

Contact the payer and ask for a corrected 1099 showing zero income. If they refuse, file your return with the correct income (zero) and keep documentation showing the payment never arrived — a bank statement, a cancelled check that bounced, or an email from the payer saying the payment failed. Respond to any IRS notice with this proof.

Is there a penalty if a payer sends a 1099 late?

Yes, but the penalty applies to the payer, not to you. The IRS can fine payers who miss the January 31 important date. You are responsible for reporting income you received regardless of whether you have a 1099, so a late 1099 doesn't excuse you from reporting it on time.
