How to File a 1099 Form and Report Self-Employment Income

What "doing a 1099" means and who has to do it

"Doing a 1099" means reporting income you earned as a self-employed person or independent contractor to the IRS. You file a 1099 when you earned money that was not subject to payroll withholding — meaning no employer took taxes out of your paychecks. The IRS expects you to report this income and pay taxes on it yourself.

You need to file a 1099 if you earned more than $400 in self-employment income during the tax year. This includes money from freelance work, gig economy jobs, rental income, or any other business you ran on your own. If you earned less than $400, you may still want to file to get a refund if taxes were withheld, but you are not required to.

The term "1099" comes from the form your clients or customers send you — Form 1099-NEC or Form 1099-MISC — which reports how much they paid you. But the actual filing you do with the IRS is on your personal tax return, usually Form 1040 with Schedule C (Profit or Loss from Business) attached.

Key Takeaways

• You report self-employment income on Schedule C, which attaches to your Form 1040 tax return, not on a separate 1099 form.
• The 1099 forms you receive from clients are informational copies for you — they also go to the IRS, so your income is already being tracked.
• You can deduct legitimate business expenses from your self-employment income, which lowers the amount you owe taxes on.
• Self-employment tax covers Social Security and Medicare and is calculated on Schedule SE, which you file with your return.
• You must file by April 15 of the year after you earned the income, or request an extension if you need more time.

Understanding the forms you receive versus the forms you file

When you work as an independent contractor or freelancer, the people who pay you send you a 1099 form by January 31 of the following year. This form shows how much they paid you. They also send a copy to the IRS. You receive this form for your records, but you do not send it back to the IRS — the IRS already has it.

The form you actually file with the IRS is your personal tax return. If you are self-employed, you attach Schedule C (Profit or Loss from Business) to your Form 1040. On Schedule C, you list all your self-employment income — including amounts from 1099 forms and any other income you earned — and subtract your business expenses. The result is your net profit, which is what you pay income tax on.

If you received 1099 forms from multiple clients, you add up all the income and report the total on Schedule C. You do not file separate returns for each 1099.

How to gather information and organize your income

Start by collecting all the 1099 forms you received. You should have one from each client who paid you $600 or more (though some industries have different thresholds). Keep these forms in a safe place — you will need them when you file your return.

Next, make a list of all your self-employment income for the year, including amounts from 1099 forms and any cash payments or income that was not reported on a 1099. Add these up to get your total income. This is the number you will use on Schedule C.

Then gather receipts and records for every business expense you want to deduct. Common deductions for self-employed people include office supplies, equipment, software subscriptions, vehicle mileage, home office rent, professional services, and health insurance premiums. Keep receipts, invoices, and bank statements as proof. The IRS may ask to see them if you are audited.

Calculating your net profit and self-employment tax

On Schedule C, you subtract your total business expenses from your total income. The result is your net profit. This is the amount the IRS considers your taxable income from self-employment.

Once you know your net profit, you use Schedule SE (Self-Employment Tax) to calculate how much you owe in Social Security and Medicare taxes. Self-employment tax is roughly 15.3% of your net profit (the exact rate varies slightly). This is in addition to regular income tax. Most self-employed people end up owing more in total taxes than someone with a regular job because they pay both the employee and employer share of Social Security and Medicare.

You can deduct half of your self-employment tax from your income before calculating your regular income tax, which provides some relief. This deduction goes on your Form 1040.

Filing your return with Schedule C and Schedule SE

You file your 1099 income by completing your annual tax return. Here is the basic order: First, fill out Form 1040 (the main personal tax return form). Then complete Schedule C with your income and expenses. Then complete Schedule SE to calculate your self-employment tax. Attach both schedules to your Form 1040 and send them to the IRS, or file electronically through tax software or a tax professional.

You can file on your own using free tax software if your situation is straightforward. The IRS Free File program offers free software to people who earn below a certain income threshold. If your situation is more complex — for example, if you have multiple income sources, rental property, or significant deductions — you may want to work with a tax professional or CPA.

The important date to file is April 15 of the year after you earned the income. If you cannot meet this important date, you can request an extension, which gives you until October 15. An extension gives you more time to file, but it does not extend the important date to pay taxes you owe — you should pay by April 15 to avoid penalties and interest.

Estimated tax payments if you expect to owe a large amount

If you earned a significant amount of self-employment income during the year, you may owe a large tax bill when you file. To avoid this and to avoid penalties, the IRS allows you to make estimated tax payments throughout the year. These are quarterly payments (due in April, June, September, and January) where you pay a portion of the taxes you expect to owe.

You are not required to make estimated payments, but if you expect to owe $1,000 or more when you file, the IRS recommends it. You calculate your estimated tax using Form 1040-ES. If you underpay, you may owe a penalty when you file your return, even if you end up getting a refund overall.

Many self-employed people set aside a percentage of each payment they receive — often 25% to 30% — and put it in a separate savings account to cover taxes. This makes it easier to pay what you owe when the bill comes due.

What to do if you did not receive a 1099 form

If a client paid you but did not send you a 1099 form, you still have to report that income on your tax return. The IRS tracks 1099 forms, and if you do not report income that was reported to them, you will likely receive a notice. Report all income you earned, whether or not you received a 1099.

If a client was supposed to send you a 1099 but did not, you can contact them and ask for it. If they refuse or cannot provide it, you can still file your return with the income you know you earned. Keep your own records — bank deposits, invoices, emails — to back up the amount.

Frequently Asked Questions

Do I have to file a 1099 if I earned less than $400?

You are not required to file if you earned less than $400 in self-employment income. However, if taxes were withheld from your payments or if you had other income, you may want to file to get a refund. Check with a tax professional if you are unsure.

Can I deduct business expenses even if I did not receive a 1099?

Yes. You can deduct legitimate business expenses from any self-employment income you report, regardless of whether you received a 1099. Keep receipts and records to support your deductions in case the IRS asks.

What happens if I file late?

If you file after April 15, you may owe penalties and interest on any taxes you owe. If you are owed a refund, there is no penalty for filing late, but you will not receive your refund until you file. You can request an extension to October 15 to give yourself more time.

Do I need to hire a tax professional to file a 1099?

You can file on your own using free tax software if your situation is straightforward. If you have multiple income sources, significant deductions, or a complex business structure, a tax professional can help you avoid mistakes and find deductions you might miss.

What is the difference between a 1099-NEC and a 1099-MISC?

Form 1099-NEC reports non-employee compensation (freelance and contract work). Form 1099-MISC reports miscellaneous income like rental payments or prizes. Both are reported the same way on your tax return — on Schedule C if it is business income.
