New York Notice of Deficiency: The Letter With the 90-Day Fuse
A Notice of Deficiency (for income tax; a Notice of Determination for some other taxes) is New York's formal assertion that you owe more tax. Publication 131 states the rule that matters: you may appeal through the Bureau of Conciliation and Mediation Services or the Division of Tax Appeals, and generally you must file your appeal within 90 days of the date the notice was issued. Miss the window and the debt hardens into a collectible bill.

The three roads from here
Agree
Pay by the notice's instructions, or set up an installment payment agreement if you cannot pay in full. Interest keeps accruing until paid.
Disagree, inside 90 days
File a protest: a conciliation conference with the Bureau of Conciliation and Mediation Services, or a petition to the Division of Tax Appeals. These are the notices the state itself lists as carrying protest rights.
Disagree, after 90 days
Formal rights are gone; per the state, if the deadline to file a protest has passed you may only submit a request for review, and submitting one does not extend your time to protest. Reviews can fix clear errors but carry no hearing rights.
After the rights expire
Collection begins where appeals end
Publication 131 is explicit about the sequence: when your appeal rights have expired or have been exhausted, the Civil Enforcement Division begins collection proceedings, with an opportunity to pay before it starts. The tools that follow are the warrant, income execution, levy, and license suspension covered later in this decoder.
Deficiency questions
How long do I have to fight a NY Notice of Deficiency?
Generally 90 days from the date the notice was issued, per Publication 131, by requesting a conciliation conference or petitioning the Division of Tax Appeals. Your notice states the exact deadline that governs your case.
Does contacting the Tax Department pause my deadline?
No. The state says plainly that submitting a request for review or contacting them does not extend your time to file a protest. Only a timely protest preserves formal rights.
What happens if I do nothing?
The assessment becomes fixed and final, and collection follows: a Notice and Demand for the balance, then civil enforcement, beginning with a tax warrant that becomes a public judgment against you.
