How Much to Set Aside for Taxes When You Earn 1099 Income

Start with 25 to 30 percent of what you earn

The simplest rule: set aside 25 to 30 percent of each 1099 payment you receive before you spend it. This covers both income tax and the self-employment tax (Social Security and Medicare) that you owe as a self-employed person. The exact percentage depends on your total income for the year, your state, and whether you have other income sources, but 25 to 30 percent is a safe starting point that keeps most people from falling short.

If you earn $1,000 on a 1099, put $250 to $300 into a separate savings account when ready. Treat that money as already gone — it belongs to the IRS, not to you. What remains is what you actually have to live on or reinvest in your work.

This approach works because you do not have an employer withholding taxes from your paycheck the way W-2 employees do. The IRS expects you to pay taxes four times a year instead, in quarterly installments. Setting aside a percentage of each payment makes those quarterly payments much easier to handle when they come due.

Key Takeaways

• Set aside 25 to 30 percent of each 1099 payment in a separate account before spending any of it.
• This percentage covers both federal income tax and self-employment tax (Social Security and Medicare combined).
• The exact amount you owe depends on your total income, your state tax rate, and whether you have other income, so 25 to 30 percent is a conservative estimate.
• Quarterly estimated tax payments to the IRS are due on April 15, June 15, September 15, and January 15 of the following year.
• If you set aside money consistently throughout the year, you can pay what you owe without scrambling when the important date arrives.

Why the percentage varies by income and state

Federal income tax is progressive, meaning you pay a higher percentage as you earn more. If your 1099 income is your only income and you earn $20,000 in a year, your federal tax rate is lower than someone earning $100,000. Your state also matters: some states have no income tax, while others tax at rates between 3 and 13 percent. A person in Florida (no state income tax) owes less than a person in California earning the same amount.

Self-employment tax is flat at 15.3 percent (12.4 percent for Social Security, 2.9 percent for Medicare), and you owe it on roughly 92.35 percent of your net 1099 income. That part does not change based on how much you earn, but it is a significant chunk that many people forget about.

Because of this variation, 25 to 30 percent is a middle-ground estimate. If you live in a no-income-tax state and earn under $50,000, you might get away with 20 percent. If you live in a high-tax state or earn over $100,000, you may need to set aside 35 to 40 percent. A tax professional can give you a more precise number based on your specific situation.

How to handle quarterly estimated tax payments

The IRS wants you to pay taxes four times a year, not all at once. These are called estimated tax payments, and they are due on April 15, June 15, September 15, and January 15 of the following year. You can pay them online through the IRS website (IRS.gov), by mail, or through your bank's bill pay system.

If you set aside 25 to 30 percent of each 1099 payment as it arrives, you will have money ready when each quarterly important date comes. Divide your total set-aside amount by four, and that is roughly what you pay each quarter. You do not have to pay the exact same amount each quarter — you can adjust based on how much you actually earned that quarter.

If you miss a quarterly payment, you can still pay when you file your tax return in April, but the IRS will charge you a penalty and interest. Setting aside money throughout the year prevents that surprise.

What happens if you set aside too much or too little

If you set aside more than you actually owe, you will get a refund when you file your tax return. That refund comes back to you, so overpaying is not a loss — it is just a free loan to the government that you get back later. Many people prefer to overpay slightly because it removes the risk of owing money they do not have.

If you set aside too little, you will owe money when you file your return in April. The IRS will charge you interest and a penalty for underpaying your estimated taxes. The penalty is usually small (around 3 to 4 percent of what you owe), but it adds up if you underpay by a lot or miss multiple quarters.

The safest approach is to set aside 30 percent rather than 25 percent if you are uncertain. The extra 5 percent is cheap insurance against a tax bill you cannot pay.

Deductions and business expenses reduce what you owe

The 25 to 30 percent rule assumes you are setting aside taxes on your gross 1099 income. But if you have business expenses — supplies, equipment, a home office, mileage, software subscriptions — you can deduct those from your income before calculating taxes. This lowers your taxable income and therefore lowers your tax bill.

For example, if you earn $10,000 on a 1099 but have $2,000 in business expenses, your taxable income is $8,000, not $10,000. You would set aside taxes on $8,000 instead. This is one reason why keeping receipts and tracking expenses matters: it directly reduces how much you owe.

However, you cannot deduct expenses you have not actually paid for, and the IRS has specific rules about what counts as a business expense. If you are unsure whether something qualifies, ask a tax professional or check IRS Publication 587 (Business Use of Your Home) or Publication 334 (Tax Guide for Small Business).

Using a tax professional to calculate your exact amount

If you want a number more precise than 25 to 30 percent, a tax professional — either a CPA or an enrolled agent — can calculate your estimated tax payments based on your actual income, expenses, and state. This costs money upfront (typically $150 to $500 depending on complexity), but it can save you from overpaying or underpaying by a large amount.

A tax professional can also help you understand whether you should be making quarterly payments at all. If your 1099 income is small and you have other income sources (like a W-2 job), you might be able to adjust your W-2 withholding instead of making separate quarterly payments.

Many tax professionals offer a one-time consultation to set up your estimated tax plan for the year, then you handle the quarterly payments yourself. This is often cheaper than having them file your entire return.

Frequently Asked Questions

Do I have to make quarterly payments, or can I just pay everything when I file my taxes?

You can pay everything in April when you file, but the IRS charges a penalty and interest if you underpay throughout the year. Quarterly payments spread the burden and avoid the penalty. If your 1099 income is very small (under $1,000 for the year), the penalty may be waived, but it is safer to pay quarterly.

What if I have a W-2 job and also earn 1099 income?

Your W-2 employer withholds taxes from your paycheck. If your total tax bill (from both sources) is covered by that withholding, you may not need to make separate quarterly payments. A tax professional can tell you whether you need to adjust your W-2 withholding or make quarterly 1099 payments.

Can I change how much I set aside if my income changes mid-year?

Yes. Estimated tax payments are based on what you expect to earn that year. If you earn more or less than expected, you can adjust your next quarterly payment. The IRS allows you to recalculate based on actual income through the previous quarter.

What if I cannot afford to set aside 25 to 30 percent?

Set aside what you can. Even if you set aside 15 or 20 percent, you will owe less in penalties than if you set aside nothing. When you file your return, you will owe the difference, but you can often set up a payment plan with the IRS if the amount is too large to pay at once.

Do I need to set aside money for state taxes too?

Yes, if your state has income tax. The 25 to 30 percent estimate includes both federal and state taxes. If you live in a state with no income tax (like Texas, Florida, or Nevada), you can set aside less. Check your state's tax website to find the state income tax rate for your income level.
