Do I Have to Pay Quarterly Estimated Taxes?

Sep 16

2 min read

If you're self-employed or run a business that doesn't withhold taxes from a paycheck, you probably do have to pay estimated taxes four times a year. The U.S. tax system is "pay as you go," so the IRS expects tax on income as you earn it — not just once in April. Generally, if you expect to owe about $1,000 or more when you file, you're on the hook for quarterly estimated payments. Skip them and you can face underpayment penalties even if you pay in full later.

Here's what that means for you.

Owner planning quarterly estimated tax payments

Who has to pay estimated taxes

The IRS guidance on estimated taxes explains that sole proprietors, partners, and S-corp shareholders generally must pay estimated tax if they expect to owe $1,000 or more. If no one is withholding tax for you, this is almost certainly you.

Don't forget self-employment tax

Estimated payments cover more than income tax. Self-employment tax — your Social Security and Medicare contributions, about 15.3% — is bundled in, which surprises many first-year owners. Setting aside a percentage of every payment you receive keeps you from scrambling at deadlines.

The four deadlines and how to stay ahead

Estimated taxes are due roughly in April, June, September, and January. The simplest system is to move a fixed percentage of each sale into a separate savings account and pay from there. Miss deadlines and penalties accrue — even a rough, on-time estimate beats a perfect, late one.

Where the how comes in

Figuring out how much to set aside, when to pay, and how to keep it painless is exactly the kind of money system new owners need. The Business Starter Program helps you set one up so taxes stop being a surprise.
