Estimated tax payments in 2026, federal and state

Who has to pay federal estimated taxes

Expect to owe $1,000 or more in net tax for the year, after subtracting withholding and credits, and you owe federal estimated tax. It doesn't matter where that money comes from: freelance work, rental income, and investment gains all push you toward the same threshold. And you owe tax on self-employment income over $400 regardless of whether a client bothers to send you a 1099.

Who has to pay state estimated taxes

Who has to pay state estimated taxes is set state by state, and California's threshold is $500, or $250 if you're married filing separately. New York's is even lower, at $300 in combined state, city, or local liability. It's entirely possible to fall under the federal $1,000 requirement and still owe a state estimated payment, which is how freelancers end up with a state penalty they never saw coming.

The 90% current-year and 100%/110% prior-year benchmarks

The 90% current-year and 100%/110% prior-year benchmarks are the safe harbor tests in Internal Revenue Code Section 6654, and clearing any one of them protects you from a penalty even if you owe a large balance when you file.³You're covered if your payments meet 90% of this year's tax, 100% of last year's tax (if your prior-year adjusted gross income, or AGI, was $150,000 or less), or 110% of last year's tax if it was higher. First-year freelancers with zero prior-year liability are exempt from the penalty entirely.

For anyone with income that's growing quickly, basing payments on 100% or 110% of last year's number is usually the simplest way to stay protected while keeping more cash on hand.

The annualized income method for seasonal income

If your income is lumpy, paying four equal installments can strain your slow months for no good reason. The annualized income installment method calculates each payment based on what you actually earned that period. It requires filing Form 2210 Schedule AI, and more careful bookkeeping, but it keeps a seasonal business from getting penalized during its off months.

California's front-loaded 30/40/0/30 schedule

California doesn't use four equal 25% installments. The Franchise Tax Board (FTB), under Revenue and Taxation Code Section 19136, collects 30% by April 15, 40% by June 15, nothing at all in September, then the final 30% by January 15.⁴

That puts 70% of your California liability due by June 15, against 50% federally by that point.

High earners lose a cushion here too. Once California AGI crosses $1,000,000 (or $500,000 if you're married filing separately), the prior-year safe harbor goes away, and you're on the hook for 90% of current-year tax instead. The state's 2026 standard deduction, for reference, is $5,706 single and $11,412 married filing jointly.

New York's combined state, city, and MCTMT payments

New York bundles everything into one voucher: state tax, New York City tax, Yonkers tax, and the Metropolitan Commuter Transportation Mobility Tax (MCTMT), all filed on Form IT-2105.⁵Brackets for 2026 run 3.90% to 10.90%, and the standard deduction sits at $8,000 single, $16,050 joint.

Self-employed and working inside the Metropolitan Commuter Transportation District? You may owe the MCTMT too, once your zone earnings cross $150,000 (that threshold jumped from $50,000 before 2026). The rate runs 0.60% in Zone 1, the five NYC boroughs, and 0.34% in Zone 2, the surrounding counties, and it applies to the whole amount once you're over the line, not just what's above it.

Interest-based penalties, not flat fines

Don't think of the underpayment penalty as a flat fee, because it isn't one. It's simple interest charged on the shortfall, calculated separately for each quarter, so paying extra in Q3 won't erase a shortfall from Q1. The federal rate for 2026 moves quarter to quarter too: 7% in Q1, 6% in Q2, back up to 7% in Q3.

Retroactive curing with late-year W-2 withholding

If you also hold a W-2 job, there's a real fix available late in the year. The IRS treats all W-2 withholding as paid evenly across all four quarters, regardless of when it was actually withheld. Realize in October that you underpaid back in April, and increasing withholding on your remaining paychecks can retroactively cover that shortfall, something a direct payment to the IRS can't do.

Federal

Federal estimated tax payments have three routes, and IRS Direct Pay is the fastest close to a deadline: it schedules a payment straight from your bank account for free. The Electronic Federal Tax Payment System (EFTPS) suits businesses making regular payments throughout the year. To mail a check, use the payment voucher from Form 1040-ES. See how to pay quarterly taxes for the full breakdown of every channel, including online account setup and what to do if a payment doesn't post.

State

State payments go through each state's own portal rather than the IRS. California's FTB Web Pay lets you pay electronically without an account, though payments over $20,000, or a return with tax due over $80,000, trigger a mandatory e-pay requirement going forward. New York's Online Services portal lets you file and pay directly from your bank account.
