Quarterly Estimated Taxes in 2026, Explained
No employer withholding means the IRS wants its money four times a year. Here's who owes, when, how much, and the penalty-proof shortcut.
Who has to pay
Anyone expecting to owe $1,000+ in federal tax beyond withholding: freelancers, 1099 contractors, rideshare and delivery drivers, small business owners, landlords with significant profit, and investors with large gains. Side-hustlers with a W-2 job can often skip quarterlies entirely by raising their W-4 withholding instead. Withholding counts as paid evenly through the year no matter when it happens.
The two numbers you're paying
- Self-employment tax: 15.3% on 92.35% of profit. This surprises every first-year freelancer: it applies even when your income is too low to owe any income tax.
- Income tax: your profit stacks on top of any other income at normal bracket rates, after the standard deduction and half your SE tax.

The penalty-proof shortcut: safe harbor
Pay 100% of last year's total tax (110% if AGI was over $150k) in four equal quarterly chunks and you cannot be penalized, even if this year's income doubles. It's the set-and-forget option for anyone with growing or unpredictable income.
New for 2025-2028: gig tips are deductible
Delivery and rideshare drivers are on the IRS tipped-occupation list, and up to $25,000 of reported tips is deductible from the income-tax side (not the SE-tax side). If tips are a big share of your income, your quarterlies just got noticeably smaller.
Frequently asked questions
What happens if I miss a quarterly payment?
The IRS charges an underpayment penalty that works like interest (currently ~8% annualized) on the shortfall from the due date. Pay as soon as you notice. The penalty stops accruing on the amount paid.
Can I just pay everything in Q4?
Not penalty-free, unless your income genuinely arrived in Q4 and you file Form 2210 with the annualized method. The IRS expects payment as income is earned.
Do quarterly payments cover Social Security and Medicare?
Yes. Self-employment tax IS your Social Security and Medicare contribution, and it earns you credit toward future benefits just like W-2 payroll tax.
