The New York State Department of Taxation and Finance is reminding taxpayers that the September 15 due date marks the third quarterly estimated tax payment deadline of the 2025 tax year. The requirement applies to individuals, partnerships, and S corporations that must pay estimated tax to stay compliant and avoid penalties.
The state requires estimated tax payments from individuals and businesses whose taxable income is not fully covered by withholding. This includes:
Taxpayers who expect to owe more than $300 in income tax after credits and amounts already withheld must also submit quarterly installments.
The New York State Department of Taxation and Finance follows a four-part schedule for the 2025 tax year:
Taxpayers can pay estimated tax in one lump sum or divide obligations into four equal installments across the year. Choosing equal installments helps spread out costs and avoid large bills when filing a tax return.
Taxpayers can make secure tax payment submissions through the state’s individual online services account. After logging in, the account summary homepage provides an expanded menu in the upper left corner, where users can select “pay” to schedule or cancel payments. This method allows taxpayers to verify, save, and review their transactions in real time.
The system of estimated tax payments follows a pay-as-you-earn process similar to the IRS. Unlike employees who have tax automatically withheld, many New York taxpayers—such as freelancers, landlords, and business owners—must calculate and pay estimated tax throughout the year. These payments apply to federal and state income tax, ensuring taxpayers avoid large bills when they file their annual tax return.
The New York State Department of Taxation and Finance notes that penalties may be imposed if payments are late or too low. To meet safe harbor rules, taxpayers must pay at least:
Following these instructions helps taxpayers maintain compliance, reduce interest, and avoid surprise money owed at the end of the tax year.
The New York State Department of Taxation and Finance emphasizes that staying current with estimated tax payments protects taxpayers from unexpected costs.
“Paying estimated tax throughout the year helps you avoid large bills, interest, and penalties when you file your annual tax return,” the department said in a recent notice.
Officials also stress the importance of choosing secure payment options, whether through an individual online services account, a tax payment voucher, or direct debit. By keeping up with each quarterly due date, taxpayers can better manage income, credits, and refund eligibility.
For millions of New York taxpayers, the September 15 due date is a key checkpoint in managing income tax obligations. Meeting this quarterly requirement helps prevent unexpected bills and penalties imposed at the end of the tax year.
Taxpayers who fail to pay on time risk added charges and interest, while those who follow the safe harbor rules can spread costs across four equal installments and avoid a lump-sum surprise when they file a tax return.
The New York State Department encourages individuals and business owners to review instructions, use online forms, and verify payments through their account. Those with unique circumstances—such as estate income, credits, or pending extension requests—should consult professionals or official guidance to ensure compliance with federal and New York State taxation rules.
