Why Freelancers Pay Quarterly
When you work a W-2 job, your employer withholds federal, NY State, and NYC tax from every paycheck. As a freelancer or 1099 contractor, nobody withholds — so the IRS and New York expect you to pay estimated tax four times a year. Miss a payment and interest (and sometimes penalties) start accruing.
2026 Due Dates
| Quarter | Period Covered | Due Date |
|---|---|---|
| Q1 2026 | Jan 1 – Mar 31 | April 15, 2026 |
| Q2 2026 | Apr 1 – May 31 | June 15, 2026 |
| Q3 2026 | Jun 1 – Aug 31 | September 15, 2026 |
| Q4 2026 | Sep 1 – Dec 31 | January 15, 2027 |
Heads up: as of this writing the next payment is Q3 — due September 15, 2026.
How Much to Pay
Your estimated tax should cover:
The Safe Harbor Rule
You can avoid underpayment penalties entirely if you pay at least 100% of last year's tax (or 110% if your prior-year AGI was over $150,000, or $75,000 married filing separately). Otherwise, pay at least 90% of this year's actual tax by the due dates. The safe harbor is why many freelancers simply base each payment on last year's return.
Example: $100,000 NYC Freelancer
For a single NYC freelancer with $100,000 in net self-employment income, 2026 estimated payments look like:
| Component | Annual Amount |
|---|---|
| Self-employment tax | $14,130 |
| Federal income tax | $11,616 |
| NY State tax | $4,421 |
| NYC tax | $3,167 |
| Total | $33,334 |
| Per quarter (4 payments) | ~$8,334 |
How to Pay
Federal (Form 1040-ES): pay online at IRS Direct Pay, via the IRS2Go app, or by mailing the 1040-ES vouchers. Electronic payments are free.
New York (Form IT-2105): pay online at tax.ny.gov (free with a NYS online account), or mail the IT-2105 vouchers with your payment. One NY payment covers both state and NYC tax.
Common Mistakes
Make It Automatic
The single best freelancer habit: transfer 30–35% of every client payment into a separate tax account the day it lands, then pay the four installments on schedule. Run your own numbers in the self-employment calculator, and see our full self-employment NY tax guide for deductions and S-corp considerations.
The Tests New York Actually Applies
New York does not simply say that freelancers pay quarterly. It applies two tests, and the floor rules out more people than most guides admit.
| Test | What it says |
|---|---|
| Balance-due floor | No estimated tax is required if you expect to owe less than $300 of New York State tax, less than $300 of New York City tax, and less than $300 of Yonkers tax after withholding and credits |
| Withholding test | No payments are due if the tax withheld during 2026 is at least 90% of the tax shown on your 2026 return |
| Prior-year test | Or if withholding covers at least 100% of the tax shown on your 2025 return |
| High-income prior-year test | 110% of that figure when your 2025 New York adjusted gross income was more than $150,000, or more than $75,000 if you are married filing separately |
Three details decide real cases:

Which Income Wants a Payment
The Department's list of income that triggers estimated payments is longer than "freelance invoices", and every line on it is income nothing was withheld from:
| Income type | Why the Department expects a payment |
|---|---|
| Self-employment income | No employer withholds |
| Self-employment allocated to the Metropolitan Commuter Transportation District | Also triggers the mobility tax |
| Capital gains, interest and dividends | Investment income arrives with nothing withheld |
| Rental income | Net rent is unwithheld |
| Pension and annuity income | Retirement income from sources that do not withhold |
| Prize winnings, lottery and horse-racing proceeds | Award income carries no withholding |
| Windfall income | Any unanticipated income no one withheld against |
| New York-source partnership or S corporation income | Reported on the entity's return, or paid in by you |
What Underpaying Costs in New York
The Department resets interest rates every quarter, and the income tax underpayment rate for the quarter ending December 31, 2026 is 9.5% per annum, compounded daily. The overpayment rate for the same quarter is 6%.
| Item | Rate for the period 10/1/2026 to 12/31/2026 |
|---|---|
| Income tax underpayment | 9.5% per annum, compounded daily |
| Income tax overpayment | 6% per annum, compounded daily |
| Corporation tax underpayment, for comparison | 11% per annum |
The rate is charged against each installment you fell short of, so a missed April payment costs more than a missed January one: that money has simply been outstanding for longer. It is also the practical argument for paying the whole safe-harbor amount with the first installment, which the due-dates page explicitly allows.

When the Calendar Does Not Fit Your Business
Two groups are carved out of the four even dates above, and both are handled in the Department's own instructions rather than on the summary pages:
If you fall into either group, work from the Form IT-2105 instructions rather than the summary page, then confirm the amount on the return.
Paying Without a Paper Trail
Everything above assumes you can pay on time, so make the mechanics boring:
