Let’s get started.

Why You Shouldn’t Ignore a Tax Notice

Ignoring a tax notice is never a good idea. Missing a deadline can lead to penalties, interest, or even more serious enforcement actions. Most notices are not emergencies—they’re often routine checks, reminders, or requests for information—but the clock starts ticking the day the notice is issued.

Common notices small businesses or independent professionals might receive include:

Request for Information (RFI): Asking for supporting documents, like receipts or W-2s.
Audit or review notices: Indicating the Department of Taxation and Finance is reviewing your return.
Bills or assessments: Showing what you owe in taxes.
Reminder-to-file letters: A gentle nudge to submit a return.

Understanding the type of notice you received is the first step to responding correctly.

Ignoring a notice can lead to penalties, interest, and stronger enforcement actions over time. For a clear picture of how consequences escalate if a New York State tax notice goes unanswered, see our step-by-step timeline of what happens if you ignore a NY tax notice.

Understanding Your Notice

Before you do anything online, read your notice carefully. Check for:

Notice number and form number: Usually at the top or bottom-left corner.
Deadline: Most notices give 30–90 days to respond. Missing this can cost money.
Type of action required: Are you paying, submitting documents, or disputing something?

Tip: Some notices are just reminders to file a tax return, like Form AU-222. These can often be handled differently from formal bills or audits.

Preparing to Respond Online

Table neatly organized with tax returns, receipts, and financial documents arranged in orderly piles.

Now that you know what the notice is asking for, gather all the necessary documents.

Step 1: Collect Your Documentation

Tax returns, W-2s, 1099s.
Receipts or invoices supporting deductions.
Proof of payments, such as child care, tuition, or business expenses.
Any other documents listed in the notice or related checklists on the NYS Tax Department website.

Step 2: Digitize Your Documents

Use a scanner or take clear photos with your phone.
Accepted formats: PDF, JPEG, DOCX, TIF, BMP, GIF, or TXT.
Maximum combined size per submission: 50 MB.
Tip: Name files clearly (e.g., 2025_W2_ABCCompany.pdf).

Having everything ready before you log in saves time and ensures you don’t miss anything.
