Every estimated tax due date for self-employed workers and 1099 contractors — plus what happens if you miss one and how to catch up.
You are generally required to make quarterly estimated tax payments if you expect to owe $1,000 or more in federal tax after subtracting withholding and credits. This applies to:
For most freelancers earning above $40,000 annually, that $1,000 threshold is easily crossed — self-employment tax alone (15.3%) on modest income pushes you there quickly.
| Quarter | Income Period | Due Date | Status |

Despite being called "quarterly" payments, the IRS payment periods are not equal three-month blocks. Q2 covers only two months (April and May), while Q3 covers three months (June through August). This asymmetry trips up thousands of freelancers who budget as though each quarter is the same length.
The practical implication: after the April 15 deadline, you have only 62 days before the next payment is due. Plan accordingly — set a calendar reminder for June 1st so you're never caught unprepared.
Missing a quarterly estimated tax payment doesn't mean you owe a late penalty in the traditional sense. Instead, the IRS charges an underpayment penalty — calculated like interest — on the shortfall from the due date until you pay it or until April 15 of the following year.
The IRS underpayment penalty rate is the federal short-term interest rate plus 3 percentage points, adjusted each quarter. On a $3,000 shortfall for a full quarter at a 7% annual rate, that's roughly $52 in penalty — not devastating, but avoidable.
The IRS gives you two safe options. Pay whichever is smaller:
For most freelancers with variable income, the prior-year method is safer — you know exactly what last year's tax was, eliminating the guesswork of projecting current year income.
A practical rule of thumb: set aside 25–30% of every payment you receive into a dedicated savings account. For freelancers in higher tax states or brackets, 30–35% is more appropriate. Transfer your quarterly payment directly from that account when the deadline arrives.
The IRS offers several ways to make estimated tax payments:

This only works if you file and pay by January 31 — it doesn't apply to extensions.
