Step 1: Figure Out Which Years Are Missing

Before you file anything, get a clear picture of what’s outstanding. On the federal side, request your IRS account transcript for each year in question. This shows whether the IRS has already filed a substitute return on your behalf (called an SFR — Substitute for Return), what income they have on record, and any assessments or penalties already applied.

For New York State, contact the NY DTF or log into your Online Services account to see which state returns are missing. The DTF also files estimated assessments when returns aren’t filed, and those assessments are almost always higher than what you’d actually owe because they don’t include any deductions or credits.

We had a client last year who thought he owed $45,000 to New York State based on the assessment notice. After filing the actual returns with proper deductions, the real liability was $11,000. That’s a $34,000 difference — and it only happened because he finally filed.

Step 2: Gather Your Income Records

You need W-2s, 1099s, and any other income documentation for each unfiled year. If you don’t have them, the IRS stores wage and income transcripts going back about 10 years. Request them using Form 4506-T or pull them online through your IRS account.

New York State receives copies of all federal W-2s and 1099s issued to New York residents, so the DTF already knows your income. That’s part of why their estimated assessments are so accurate on the income side — and so punishing on the deduction side, since they assume zero deductions when you don’t file.

Step 3: File Federal Returns First

Always start with the IRS. Your New York State return pulls numbers from your federal return (adjusted gross income, itemized deductions, federal tax liability), so you need the federal return done before the state return makes sense.

The IRS typically requires only the last six years of returns to consider you in compliance. If you haven’t filed in 10 years, you technically have an obligation for all 10, but the IRS enforcement division usually focuses on the most recent six. File those, get current, and the older years often become a lower priority.

One catch: if you’re owed a refund for an old year, you only have three years from the original due date to claim it. Miss that window and the refund disappears. This happens more than you’d think — someone doesn’t file for 2021, was owed a $4,000 refund, and by the time they get around to filing in 2025, it’s gone.

Step 4: File New York State Returns

Once your federal returns are done, prepare and file the corresponding New York State returns (Form IT-201 for full-year residents, IT-203 for part-year or nonresidents). If you lived in NYC during any of the unfiled years, the city tax is calculated on the same return.

New York has no statute of limitations on unfiled returns. If you owe tax and never filed, the DTF can pursue that balance indefinitely. This is different from the IRS, which generally has 10 years from the date of assessment to collect. So while the IRS debt might eventually expire, the New York State debt won’t — not until you file.

The NY DTF Collection Process

The New York Department of Taxation and Finance has its own collection process that runs independently of the IRS. Here’s what to expect if you have outstanding state tax debt:

• Assessment notices: The DTF sends a series of notices (N-series) giving you a chance to respond before escalating.
• Tax warrants: If you don’t respond, the DTF files a tax warrant with the county clerk. This becomes a public lien against your property — it shows up on credit reports and attaches to any real estate you own in New York.
• Bank levies and wage garnishment: The DTF can freeze your bank accounts and garnish wages without going to court. They send the levy notice directly to your bank or employer.
• Driver’s license suspension: For debts over $10,000, New York can suspend your driver’s license. This is not a bluff — the DMV actually processes these.

The DTF moves faster than the IRS on collections. We’ve seen bank accounts frozen within 60 days of a final notice. Don’t wait for the warrant stage to take action.

Penalties and Interest for Late Filing

Federal penalties include a failure-to-file penalty (5% per month up to 25% of unpaid tax) and a failure-to-pay penalty (0.5% per month up to 25%). These run concurrently. Interest accrues on top of both, compounded daily.

New York State imposes its own late-filing penalty of 5% per month (up to 25%) plus a late-payment penalty of 0.5% per month (up to 25%). The state interest rate is set quarterly and typically runs 7-9%. Both federal and state penalties stack — you owe both if you filed neither.

The math gets ugly fast. A $10,000 federal balance left unfiled for three years can turn into $15,000-$18,000 with penalties and interest. Add the corresponding state balance and you’re looking at double that. The longer you wait, the more expensive waiting becomes.

Payment Options Once You’re Filed

If you can’t pay the full balance when you file, both the IRS and NY DTF offer installment agreements. The IRS allows monthly payments through an Online Payment Agreement for balances up to $50,000. New York State offers similar installment plans through their Online Services portal.

For larger federal debts or situations where paying in full would cause genuine financial hardship, the IRS has an Offer in Compromise program that settles the debt for less than the full amount. The acceptance rate is low — around 30-35% of applications — and the IRS reviews your income, expenses, and assets in detail before agreeing to a reduced amount. New York State has a similar program, but it’s even more selective.
