When are your quarterly estimated taxes due?

Next federal estimated tax date (2026 tax year)

Fri, Jan 15, 2027

Q4 payment (income Sep 1 - Dec 31). You can skip it if you file your 2026 return by Feb 1, 2027 and pay the full balance with it.

If you drive for apps, freelance, sell online or run a small business, nobody withholds tax for you. The IRS expects payments during the year, and the four dates are not three months apart. Federal dates for the 2026 tax year:

Who generally has to pay?

Individuals, including sole proprietors, who expect to owe $1,000 or more in tax when they file, after withholding and refundable credits. Source: IRS: Estimated taxes · last verified 2026-10-17
You generally avoid the penalty if you pay at least 90% of this year's tax or 100% of last year's tax, whichever is smaller (110% of last year's if last year's AGI was over $150,000, or $75,000 if married filing separately). Source: IRS: Estimated tax FAQ · last verified 2026-10-17
Gig income must be reported even without a 1099, and you must file if net self-employment earnings are $400 or more. Source: IRS: Manage taxes for your gig work · last verified 2026-10-17 (IRS page reviewed 28-Jun-2026)
If you also have a job, you may be able to cover gig tax by raising W-4 withholding instead (see free tools).

Why this site exists

Many calculators ask for an email or sell software. This one is a plain reference: official dates, source links and last-checked dates, no signup. It is one resource among several, not a replacement for the IRS, your state agency or a preparer.
