How the New York quarterly estimated tax calculator works
This calculator estimates both federal and New York state quarterly tax obligations for a self-employed person in 2026.
Federal estimated tax
The federal calculation follows IRS Form 1040-ES: SE tax on 92.35% of net profit at 15.3%, reduced by the deductible half (reducing AGI), then federal income tax on taxable income (AGI minus standard deduction, minus optional QBI deduction). The result minus withholding is divided by 4 for equal quarterly installments due April, June, September, and January.
New York estimated tax
New York income tax is computed on adjusted gross income minus the New York standard deduction ($8,000 single / $16,050 MFJ).
The state quarterly payment shown is one-quarter of the annual state income tax — an equal-installment approximation. Verify your state's actual schedule and threshold at NY Dept. of Taxation and Finance — 2026 tax rates (Chapter 59, Laws of 2025, Part A).
Scope and limitations
Not included: Excludes New York City income tax (3.078%–3.876% for NYC residents) and Yonkers surcharge. NYC residents should add city tax on top of this estimate. NY SDI (State Disability Insurance) and PFML (Paid Family and Medical Leave) payroll contributions are also excluded. State-specific credits, local income taxes, and penalties for underpayment are not modeled. The state estimated tax base may differ from the federal base in ways not captured here.
Use this for planning, not filing. Federal figures from IRS Rev. Proc. 2025-32; state figures from NY Dept. of Taxation and Finance — 2026 tax rates (Chapter 59, Laws of 2025, Part A) for 2026.

Frequently asked questions
Does New York require quarterly estimated tax payments?+
Yes. New York requires estimated tax payments if you expect to owe at least $300 in NY income tax after credits and withholding. NY uses the standard April/June/September/January schedule. Form IT-2105 is used. NYC residents should add NYC income tax (3.078%–3.876%) to their quarterly payments — NYC tax is not included in this calculator.
Do I owe NYC estimated income tax as a freelancer?+
If you live in New York City, yes — you owe NYC income tax on your freelance income and should include it in your quarterly estimated payments. NYC income tax is filed with your NY state return (Form IT-201). This calculator shows NY state tax only; your actual quarterly payment as a NYC resident should include the NYC rate as well.
Do freelancers in New York owe state estimated taxes in addition to federal?+
Yes. Freelancers in New York who expect to owe more than $500 in state income tax (threshold varies; check with the New York Department of Revenue) are generally required to make quarterly estimated state tax payments. These are separate from your federal 1040-ES payments.
When are federal estimated tax payments due in 2026?+
Federal estimated tax payments for 2026 are due on: April 15 (Q1), June 16 (Q2, adjusted from June 15), September 15 (Q3), and January 15, 2027 (Q4). Missing a payment or underpaying may result in a penalty under IRS Form 2210, even if you pay in full by April 15.
How is the quarterly estimated tax amount calculated?+
The calculator estimates your annual tax liability: (1) SE tax on 92.35% of net profit × 15.3%; (2) federal income tax on taxable income (AGI minus standard deduction, minus optional QBI deduction); (3) state income tax using your state's rates and deduction rules. It then subtracts withholding and divides by 4 (federal) or applies the state's installment schedule.
What happens if I underpay federal estimated taxes?+
The IRS charges a penalty for underpaying estimated taxes (Form 2210). For 2026, the penalty rate is approximately 7–8%. To avoid the penalty, pay either 90% of this year's tax or 100% of last year's tax (110% if last year's AGI exceeded $150,000). Using the safe harbor based on last year's return is often the simplest approach for freelancers with variable income.
Should I pay estimated taxes monthly rather than quarterly?+
The IRS and most states require quarterly (not monthly) estimated tax payments. However, you can pay more frequently or in advance of due dates — overpaying is not penalized. Many freelancers find it easier to set aside a fixed percentage of each invoice payment and make monthly deposits, then ensure each quarterly deadline's cumulative amount meets the required installment.
