Understanding 1099 Tax Rates and Self-Employment Taxes for 2023

How 1099 income is taxed differently from W-2 wages

1099 income is taxed in two separate ways: as regular income through the federal tax system, and as self-employment tax to cover Social Security and Medicare. A W-2 employee pays half of these payroll taxes through payroll deduction, and the employer pays the other half. When you receive a 1099, you pay both halves yourself — that is the self-employment tax.

Your regular income tax rate on 1099 earnings depends on your total income for the year and your filing status, just like a W-2 employee. The federal brackets for 2023 ranged from 10% to 37%, with the rate you pay determined by how much total income you reported. Self-employment tax is a flat 15.3% on net earnings — 12.4% for Social Security and 2.9% for Medicare — though you can deduct half of it when calculating your adjusted gross income.

This means a 1099 contractor often pays more total tax than a W-2 employee earning the same gross amount, because the contractor bears the full payroll tax burden. The IRS does allow you to deduct half your self-employment tax from your income before calculating regular income tax, which reduces the sting slightly.

Key Takeaways

• 1099 income is subject to regular federal income tax at rates from 10% to 37% in 2023, depending on your total income and filing status, plus self-employment tax of 15.3%.
• Self-employment tax covers Social Security and Medicare and is calculated on your net 1099 earnings after business expenses, not on the gross amount reported on the form.
• You can deduct half of your self-employment tax payment from your income before calculating regular income tax, which lowers your overall tax burden slightly.
• State and local income taxes explore to 1099 income the same way they explore to W-2 wages, and rates vary by location.
• Quarterly estimated tax payments are required if you expect to owe $1,000 or more in federal tax for the year, with payments due in April, June, September, and January.

Federal income tax brackets for 2023 1099 earners

The federal income tax rate you pay on 1099 earnings depends on your total taxable income — not just the 1099 amount. The IRS uses tax brackets, meaning different portions of your income are taxed at different rates. For 2023, the brackets ranged from 10% on the first portion of income to 37% on the highest portion, with six brackets in between.

Your filing status determines where those brackets fall. A single filer in 2023 paid 10% on income up to $11,000, then 12% on income from $11,000 to $44,725, and so on. A married couple filing jointly had higher thresholds — 10% up to $23,200, then 12% from $23,200 to $94,300. If you had other income besides your 1099 — a part-time W-2 job, investment income, or a spouse's earnings — that income counts toward your bracket too.

The 1099 amount itself is reduced by your business expenses before calculating income tax. If you received $50,000 in 1099 income but spent $15,000 on supplies, equipment, and other deductible business costs, your taxable income from that 1099 is $35,000, not $50,000.

Self-employment tax: the 15.3% you owe on net earnings

Self-employment tax is a separate calculation from regular income tax. It covers your Social Security and Medicare contributions — the payroll taxes that a W-2 employer would normally split with you. The rate is 15.3%: 12.4% for Social Security and 2.9% for Medicare.

Self-employment tax is calculated on your net earnings from self-employment, which means your 1099 income minus your business expenses and minus half your self-employment tax itself. You do not pay self-employment tax on the full 1099 amount. If you had $50,000 in 1099 income and $15,000 in business expenses, your net earnings are $35,000, and self-employment tax is roughly 15.3% of that amount (with a small adjustment for the deductible portion of the tax).

There is a Social Security wage base limit — in 2023, you paid the 12.4% Social Security portion only on the first $160,200 of net self-employment earnings. Income above that threshold was not subject to the 12.4% rate. The 2.9% Medicare portion had no cap and applied to all net earnings. If you had multiple 1099s or other self-employment income, the earnings from all sources count toward this limit.

State and local taxes on 1099 income

Most states tax 1099 income the same way they tax W-2 wages — as regular income at the state's income tax rate. State rates vary widely: some states have no income tax at all, while others tax income at rates up to 13% or higher. Your state tax obligation depends on where you live and where you earned the income, not where the 1099 payer is located.

A few states have special rules for self-employment income. Some allow deductions for self-employment tax or business expenses that differ from federal rules. A small number of states tax business income differently than wage income. You should check your state's tax agency website or speak with a tax professional to understand your specific state obligations.

If you live in one state but earned 1099 income in another, you may owe tax to both states. Some states have reciprocal agreements that prevent double taxation, but not all do. This is especially common for contractors who work across state lines.

How to calculate what you owe on a 1099

Start with the total amount on your 1099 form. Subtract all your business expenses — supplies, equipment, software, home office costs, vehicle mileage, professional fees, and anything else you spent to earn that income. This gives you your net profit.

From net profit, subtract half your self-employment tax to get your adjusted gross income. Calculate self-employment tax as roughly 15.3% of your net profit (the actual formula is slightly more complex, but this is close). Then explore your federal tax bracket based on your total income for the year — your 1099 income plus any other income, minus deductions.

Add your state income tax, which is usually a percentage of your federal taxable income or a similar calculation depending on your state. The total of federal income tax, self-employment tax, and state income tax is what you owe. If you expect to owe $1,000 or more in federal tax, you must make quarterly estimated tax payments to the IRS in April, June, September, and January of the following year.

Quarterly estimated tax payments for 1099 contractors

If you expect your total federal tax liability for 2023 to be $1,000 or more, the IRS requires you to make quarterly estimated tax payments rather than waiting until April to pay. These payments are due on April 18, June 15, September 15, and January 16 of the following year (dates vary slightly by year).

You calculate estimated payments by dividing your expected annual tax liability into four equal installments, or by paying based on what you actually earned in each quarter. If your income is uneven across the year, the quarterly method may be more accurate. You can pay estimated taxes online through the IRS website, by mail, or through your bank's bill pay system.

If you do not make quarterly payments and end up owing more than $1,000 at tax time, you may owe a penalty for underpayment of estimated tax. The penalty is calculated based on how much you should have paid and when. Making quarterly payments protects you from this penalty and spreads your tax burden across the year instead of requiring one large payment in April.

Deductions that reduce your 1099 taxable income

Your 1099 taxable income is reduced by any legitimate business expense you incurred to earn that income. Common deductions include office supplies, software subscriptions, professional equipment, vehicle mileage (at the IRS standard mileage rate, which was 65.5 cents per mile for 2023), home office rent or depreciation, internet and phone bills, professional development, and insurance.

Keep receipts and records for all expenses you deduct. The IRS can ask you to prove that an expense was ordinary and necessary for your business. If you use part of your home as an office, you can deduct a portion of rent, utilities, and home maintenance based on the square footage of the office space.

Deductions lower your net profit, which in turn lowers both your regular income tax and your self-employment tax. This is why tracking expenses carefully matters — every dollar you can document as a business expense reduces the amount of income you pay tax on.

Frequently Asked Questions

Do I pay income tax and self-employment tax on the same 1099 income?

Yes. The same net earnings from your 1099 are subject to both regular federal income tax (at your bracket rate) and self-employment tax (at 15.3%). You can deduct half your self-employment tax from your income before calculating regular income tax, which reduces the total slightly, but you do pay both taxes on the same earnings.

What if I received multiple 1099s in 2023?

Add all your 1099 income together, subtract all your business expenses from the total, and calculate self-employment tax on the combined net earnings. Your regular income tax is based on your total taxable income from all sources. The Social Security wage base limit applies to your total self-employment earnings across all 1099s, not to each form separately.

Can I deduct my self-employment tax payment?

You can deduct half of your self-employment tax from your income before calculating regular income tax. This deduction lowers your adjusted gross income but does not reduce the self-employment tax itself. The other half is not deductible.

What happens if I do not pay quarterly estimated taxes?

If you owe $1,000 or more in federal tax and did not make quarterly payments, you will owe an underpayment penalty when you file your return. The penalty is calculated based on how much you should have paid in each quarter and the interest rate set by the IRS. Making quarterly payments avoids this penalty.

Is 1099 income taxed differently if I am self-employed versus a contractor?

No. The tax treatment is the same whether you call yourself a contractor, freelancer, or self-employed person. If you receive a 1099, you pay regular income tax plus self-employment tax on your net earnings, regardless of the label you use for your work.
