Short answer: The Q1 estimated tax payment (covering income earned January-March) is due mid-April, the same day as your annual return. Most freelancers who owe $1,000+ for the year are required to pay quarterly — missing it triggers an IRS underpayment penalty even if you pay everything in full the following April.

How to calculate your Q1 payment
The simplest reliable method: take your actual Q1 net income, apply your 30% set-aside rule estimate, and pay that amount. If your income is highly irregular quarter to quarter, this “actual income” method is generally more accurate than dividing your prior year’s total tax bill by four, which can badly over- or under-estimate a volatile quarter.
⚠️
If Q1 was a slow quarter, don’t skip the payment entirely — pay based on what you actually earned. The IRS calculates penalties per quarter, so a skipped Q1 payment isn’t offset by overpaying later in the year.
What happens if you miss it
The IRS charges an underpayment penalty calculated roughly like short-term interest on the unpaid amount, from the missed deadline until it’s paid. It’s rarely catastrophic for a single missed quarter, but it compounds if multiple quarters are missed across the year. If you’re behind, pay what you can as soon as possible — the penalty calculation is based on time elapsed, so paying late is still meaningfully better than not paying until the annual deadline.

Frequently asked questions
Do I need to pay quarterly taxes if this is my first year freelancing? +
If you expect to owe $1,000 or more for the year, yes, even in your first year. New freelancers often underestimate this because there’s no employer withholding to make the obligation obvious.
Can I pay more than the minimum in Q1 to get ahead? +
Yes — overpaying an early quarter is fine and simply reduces what you owe later or increases your refund. There’s no penalty for overpaying, only for underpaying relative to what you actually owed that quarter.
What if my income varies wildly between quarters? +
The IRS’s “annualized income installment method” exists specifically for this situation and can reduce penalties compared to the standard even-split method — worth discussing with a tax professional if your income is highly seasonal or project-based.
Is there a safe harbor that avoids the penalty entirely? +
Yes — paying at least 100% of last year’s total tax bill (110% if your prior-year income was high) spread across the four quarters generally avoids the underpayment penalty regardless of this year’s actual income, though you may still owe a balance in April if this year’s income is higher.
