Filing a 1099 usually lowers your refund, not raises it

A 1099 form reports income you earned as a contractor, freelancer, or from investments. When you file it with your tax return, the IRS counts that income toward your total. More income means you owe more tax, which shrinks your refund or turns it into a bill you owe instead.

The size of the change depends on how much 1099 income you report and what tax bracket you fall into. If you earned $5,000 on a 1099 and owe 22% federal tax on it, that's roughly $1,100 in additional tax. If you were expecting a $2,000 refund, filing that 1099 could cut it to $900 — or flip it to a $1,100 bill.

The only way a 1099 increases your refund is if you claim deductions or credits that offset the income, or if the 1099 issuer already withheld taxes from those payments. Most 1099 income has no withholding, so you end up owing more when you file.

Key Takeaways

  • 1099 income is taxable and increases your total reported income, which usually reduces your refund or creates a tax bill.
  • The impact depends on your tax bracket and how much 1099 income you earned — higher income means a larger reduction in your refund.
  • If you are self-employed, you can deduct business expenses against 1099 income, which lowers the taxable amount and reduces the refund impact.
  • Some 1099 payers withhold taxes (backup withholding), which counts as a payment toward your tax bill and can increase your refund if you overpaid.
  • You must report all 1099 income even if you did not receive a form — the IRS has a copy and will catch unreported amounts.

Why 1099 income reduces your refund

When you earn money as a contractor or freelancer, the person or business that paid you sends you a 1099 form and sends a copy to the IRS. That form tells the IRS you earned that money. Your tax return must include it, and the IRS will match what you report against the copy they received.

Unlike W-2 wages, where your employer withholds federal income tax, Social Security, and Medicare automatically, 1099 income usually has no withholding. You receive the full amount and are responsible for paying tax on it when you file. The more 1099 income you report, the higher your total income, and the more tax you owe.

If you were counting on a refund because you thought your income was lower, adding 1099 income changes that math. A $3,000 refund can become a $1,000 refund, or you might owe money instead.

How self-employment deductions can offset the impact

If you are self-employed, you can deduct legitimate business expenses against your 1099 income. These deductions reduce your taxable income, which means less tax owed and a smaller hit to your refund.

Common deductions include office supplies, equipment, vehicle mileage (at the IRS rate, currently 67 cents per mile for 2024), home office space, software subscriptions, and professional services. If you earned $10,000 on a 1099 but spent $3,000 on deductible expenses, you only owe tax on $7,000 of income.

You report these deductions on Schedule C (Profit or Loss from Business) when you file your return. Keep receipts and records for everything you claim. The more legitimate deductions you have, the more you reduce the refund impact of your 1099 income.

Backup withholding and overpayment

In rare cases, the IRS requires a 1099 payer to withhold 24% of your payment for backup withholding. This happens if you did not provide a valid tax ID, did not respond to IRS notices, or had a previous underreporting issue. When backup withholding occurs, that money is sent to the IRS as a tax payment on your behalf.

If backup withholding was taken from your 1099 income, that amount counts toward your total tax bill. If you overpaid overall, you get a larger refund. If you underpaid, the refund is smaller. You will see the backup withholding amount on the 1099 form itself, in box 4.

Backup withholding is not common for most freelancers and contractors. It is more likely if you have had tax compliance issues in the past.

What happens if you do not report a 1099

The IRS receives a copy of every 1099 issued to you. If you do not report it on your tax return, the IRS will notice the mismatch between what you reported and what they have on file. This triggers a notice asking you to explain the difference, and you will owe the tax plus penalties and interest.

Ignoring a 1099 does not make the income go away. The IRS will eventually catch it, and the cost of not reporting it — in penalties and interest — is far higher than the tax you would have owed if you had filed correctly the first time.

If you received a 1099 but believe it is wrong (the amount is incorrect, or you should not have received it), contact the payer and ask for a corrected form. If they do not issue one, you can file Form 8275 (Disclosure Statement) with your return to explain the discrepancy.

Comparing 1099 income to W-2 wages on your refund

The refund impact of 1099 income is usually steeper than W-2 wages because of self-employment tax. On top of regular federal income tax, 1099 earners owe Social Security and Medicare tax (15.3% combined, though you can deduct half). W-2 employees split this cost with their employer.

If you earned $10,000 as a W-2 employee, your employer withheld roughly $1,200 to $1,500 in taxes. If you earned $10,000 on a 1099, you owe roughly $2,200 to $2,500 in combined income and self-employment tax, with no withholding. The difference in refund impact is significant.

This is why many people with 1099 income end up owing money at tax time rather than receiving a refund. Planning ahead — setting aside money throughout the year or making quarterly estimated tax payments — helps avoid a surprise bill in April.

Estimated tax payments and 1099 income

If you earn significant 1099 income, the IRS expects you to make quarterly estimated tax payments throughout the year rather than waiting until April. These payments are due on April 15, June 15, September 15, and January 15 of the following year.

If you make these payments, the money counts toward your tax bill, just like withholding does. You report the total of your estimated payments on your tax return, and it reduces the amount you owe or increases your refund. Without these payments, you owe everything at once in April, and you may face an underpayment penalty.

To calculate estimated payments, you can use IRS Form 1040-ES, which walks you through the math based on your expected 1099 income for the year. Many tax software programs also calculate this for you.

Frequently Asked Questions

Can I get a bigger refund if I report 1099 income?

Only if you had taxes withheld from the 1099 payments (backup withholding) or if you claim deductions and credits that exceed your 1099 income. In most cases, 1099 income reduces your refund because it increases your taxable income with no withholding.

What if I received a 1099 but did not cash the check?

You still owe tax on it. The IRS counts income when it is earned, not when you deposit it. If the payer issued a 1099, they reported it to the IRS, and you must report it on your return regardless of whether you actually received or used the money.

Do I have to report a 1099 if the amount is under $600?

Most 1099-NEC and 1099-MISC forms are issued for $600 or more, but you must report all income you received, even if no form was issued. The IRS does not have a threshold below which income is tax-free. If you earned it, report it.

How much should I set aside for taxes on 1099 income?

A rough estimate is 25% to 30% of your 1099 income, depending on your tax bracket and whether you have deductions. This covers federal income tax, self-employment tax, and state tax if applicable. Your actual amount depends on your total income and situation, so use Form 1040-ES or tax software to calculate.

Will filing a 1099 trigger an audit?

Filing a 1099 itself does not trigger an audit. Audits are based on many factors, including income level, deduction patterns, and random selection. Reporting your 1099 income correctly reduces audit risk; not reporting it increases it significantly.
