Massachusetts Notice of Intent to Assess: 30 days before it becomes a bill
The Department of Revenue thinks you owe more and is telling you before it bills you. You have 30 days to disagree, send information, or ask for a conference with the Office of Appeals. After that, the bill arrives.
THE CLOCK — 30 DAYS FROM THE DATE OF THE NOTICE
DOR gives 30 days from the date of the NIA to discuss the proposed amount or provide information, and an appeal filed within those 30 days is a pre-assessment appeal that can include a conference. If nothing changes, DOR says the Notice of Assessment is issued in about 30 days. A payment agreement is not available until that bill arrives.
What the NIA is, and is not
DOR describes the Notice of Intent to Assess as an audit notice issued when it believes you owe additional tax. It names the reason. It is not a tax bill; it shows the amount you will owe if you do not dispute it.
Massachusetts law requires this step. Before assessing additional tax, the Commissioner must first give notice of the intention to assess, and the NIA is that notice. It is the state's version of a proposed adjustment, and like its federal cousins it is the cheapest point at which to correct the record.
If you agree, DOR says you can pay in full straight away to stop further interest and penalties, or make a partial payment. What you cannot do yet is set up a payment agreement. DOR requires a Notice of Assessment or Statement of Account first, and says good-faith payments can be made in the meantime.
Your three responses
Inside the 30 days, the choices are to agree and pay, to send information, or to appeal. They are not mutually exclusive, but they are different things, and choosing the right one matters more than speed within the window.
| RESPONSE | HOW | WHAT IT LEADS TO |
|---|---|---|
| Agree | Pay in full, or pay part now | Stops further interest on what you pay. The rest is billed on the Notice of Assessment |
| Send information | MassTaxConnect, Submit documentation, with the Letter ID from the notice | DOR reviews it. If it resolves the issue the proposed amount changes; if not, the assessment follows |
| Pre-assessment appeal | An appeal through MassTaxConnect within 30 days, the same as filing Form DR-1 | A conference with an Appeals Officer before any bill, by video, phone or in person in Boston |
| Do nothing | — | A Notice of Assessment in about 30 days, then the collection sequence |
DOR says the Submit documentation route is for correspondence only and should not be used to file a tax return.
The pre-assessment conference
DOR describes the pre-assessment conference as your opportunity to speak to an Appeals Officer after an audit but before you receive a Notice of Assessment. The request has to be made within 30 days of the NIA.
It is worth taking seriously, because it is not easily repeated. DOR says that if a pre-assessment appeal is denied you may still file for abatement, but if you already had a conference you will be granted a second one only where there is new information that was not available at the first, or a change in the law. Bring everything the first time.
What wins a conference is documentation. Records that substantiate the items the auditor disallowed, a reconciliation that explains the difference, and a clear written statement of your position, organized so the Appeals Officer can follow it.
The NIA Information Request
A different notice uses the same name. DOR sends an NIA Information Request when it needs more information to continue processing a return, typically about the Massachusetts withholding credit, the Earned Income Credit or the Circuit Breaker Credit.
It is also not a bill. It shows the credits that will be removed if you do not provide the information. You have 30 days from the notice date, and DOR asks you to include page 2 of the notice with your response. If you do not respond, the credits are taken away, which can reduce a refund or produce a bill.
Send everything with the first response. DOR says that if more is needed it issues a second request, and each round delays the return.
BEFORE THE 30 DAYS RUN OUT
- Read the reason on the notice and match it to the return and your records
- Decide whether you are sending information, appealing, or both
- Gather the documents the notice asks for, and anything else that answers the stated reason
- Respond through MassTaxConnect with the Letter ID, and keep the confirmation
- If the adjustment follows a federal change, have the federal paperwork with you
Where this comes from
The statutes behind this page, so you can check any of it rather than take it on trust.
- M.G.L. c. 62C §26(b)
- DOR's power to assess additional tax, generally within 3 years of the return, after first giving notice of its intention. The NIA is that notice.
- M.G.L. c. 62C §31
- Written notice of an assessment above the amount on the return, with the balance due and when it must be paid. This is the Notice of Assessment that follows.
- M.G.L. c. 62C §37
- Abatement after assessment, the route that remains if the pre-assessment stage passes.
This page explains what the IRS or the Massachusetts Department of Revenue does and cites the statute. It is not advice about your situation, which depends on facts none of this knows.

Notice of Assessment and Final Notice
Three letters, in order: the bill, the demand, and the warning that collection is next. The middle one matters most, because 10 days after it, unpaid and undisputed amounts can be collected by levy.
Massachusetts DOR debt
Resolving a federal balance does nothing for a state one. Massachusetts has its own assessment periods, its own collection powers, its own appeal route and its own personal liability rule for trustee taxes.
DOR payment agreement
A payment plan with the Department of Revenue has two tiers, split by the size of the balance. The smaller tier can be set up online; the larger one needs a financial statement and documents. Both need every return filed first.
Notice CP2000
An automated comparison found income reported to the IRS that does not appear on your return. The proposed tax is frequently much larger than the correct answer, because the computer does not know what anything cost you.
Questions about notice of intent to assess.
- Is a Massachusetts NIA a tax bill?
- No. DOR says the Notice of Intent to Assess is an audit notice, not a bill. It shows what you will owe if you do not dispute it. The bill is the Notice of Assessment, which DOR says is issued in about 30 days if nothing changes.
- How long do I have to respond to an NIA?
- DOR gives 30 days from the date of the notice to discuss the proposed amount or provide more information. A pre-assessment appeal, which can include a conference with an Appeals Officer, must also be filed within those 30 days.
- Can I set up a payment plan after an NIA?
- Not yet. DOR requires a Notice of Assessment or a Statement of Account before a payment agreement. It says you can make good-faith payments while you wait, which reduces the interest that builds on the balance.
- What is a pre-assessment conference?
- A meeting with a DOR Appeals Officer after an audit but before a Notice of Assessment. It is requested through an appeal filed within 30 days of the NIA, and can be held by video, by phone or in person at DOR's Boston office.
- What if I miss the 30 days?
- DOR issues the Notice of Assessment. You can still dispute the tax afterward through an application for abatement, within the periods state law allows, but the pre-assessment conference is no longer available.
