New Hampshire Notice of Tax Assessment Checklist
A New Hampshire Notice of Assessment is a formal document from the state informing you that you owe a calculated tax amount or that a return you already filed has been adjusted. This notice creates an official record that the state has taken action on your tax account, and responding appropriately prevents the situation from becoming more serious.
What This Notice Means
The state issues a Notice of Assessment when it determines that you owe a specific tax amount. The document will show the tax year, the type of tax assessed, such as business profits tax or business enterprise tax, and the total amount due.
Why the State Sent This Notice
The state sends a Notice of Assessment when it detects unreported income, determines that you underpaid your tax liability, assesses penalties for late filing or payment, or makes corrections after reviewing your return. Prior notices may have gone unanswered, and this assessment formalizes what you owe.
Sometimes an assessment may be made without an audit based on information the department receives. Creating an official record and providing you with an opportunity to respond before taking further enforcement steps serve as the primary purposes of this notice.
What Happens If You Ignore This Notice
Failure to respond allows the state to pursue collection actions under New Hampshire law. Under RSA 21-J:28-c, the department can file a lien on your property that continues for six years from the filing date or until the liability is satisfied.
What This Notice Does Not Mean
This notice does not mean you have been criminally charged or that you will automatically face criminal prosecution. The department has not frozen your accounts, seized your property, or filed a lien—those are separate enforcement actions that occur later if the debt remains unpaid.
What to Do After Receiving This Notice
Review the notice and identify key information: Read the entire document carefully and locate the tax year in question, the type of tax being assessed, the amount owed, and any deadline for response.
Find the deadline date on the notice: Most tax notices include a date by which you must respond or pay, so locate this date and record it on a calendar or in your phone.
Gather your tax records related to the year in question: You will need your original tax return for that year, any documents you filed with it, bank statements, income records, receipts, and any previous correspondence with the department. Keep these organized in one place because you will need them to verify whether the assessment is correct.
Review the assessment for accuracy: Compare what the notice states you owe to your own records, checking whether the income reported matches what you reported on your return. Verify that penalties were properly applied and look for obvious errors such as misread numbers or doubled amounts.
Decide whether you agree or disagree: Your review will help you determine whether the calculation appears correct. Note specifically what is incorrect and why if you believe the assessment contains errors.
Contact the Department of Revenue Administration if you have questions: Unclear information or missing details warrant immediate clarification from the department using the contact information provided on the notice.
Prepare a written response if you disagree with the assessment: You have the right to file an appeal with the Hearings Bureau within sixty days after receiving the notice. Your response should explain which part of the assessment you disagree with, what the correct amount should be according to your records, and why.
Include copies of documents that support your position and send this response to the address listed on the notice. An appeal sent by mail will be considered timely filed if postmarked on or before the expiration of the sixty-day period.
Contact the department to discuss payment options if you agree but cannot pay immediately: Request an installment payment agreement through Granite Tax Connect or by contacting the Taxpayer Services Division if the assessment is correct, but you cannot pay the full amount by the deadline. When the department grants a request for an installment payment agreement, it delivers a written installment payment agreement to you.
Follow your payment arrangement exactly: Missing payments on an installment agreement can result in the entire remaining balance becoming due immediately and enforcement action restarting.
Keep copies of everything you send and document all contacts: Mail your response using certified mail or through a delivery service that provides tracking to confirm receipt. Write down the date, time, and name of the person you spoke with during any phone calls, along with what was discussed.
Watch for any follow-up notices or responses: Monitor your mail for the department’s reply to your dispute, payment request, or other communication.
Common Mistakes to Avoid
● Waiting until after the deadline to respond or contact the department limits your options and can allow enforcement action to proceed.
● Sending original documents instead of copies can result in permanent loss of important records.
● Assuming the assessment is correct without reviewing it against your own records may cause you to pay more than you actually owe.
● Throwing away the notice because you feel worried or upset prevents you from accessing important information and deadlines.
Frequently Asked Questions
Does receiving this notice mean I will go to jail?
A Notice of Assessment is part of the civil tax collection process, not a criminal process. Civil tax collection involves remedies such as liens, while criminal prosecution is separate and involves different procedures and evidence standards.
What if the deadline on the notice has already passed?
Contact the Department of Revenue Administration immediately because passing the deadline does not automatically end your rights. Explain that you are contacting them after the deadline and ask what options remain available.
Can I appeal the final decision?
If you disagree with the final decision, you may appeal within thirty days by written application to the board of tax and land appeals or the superior court in the county where you reside or have a place of business.
Receiving a Notice of Assessment is stressful, but it represents a standard part of how states collect taxes and resolve disputes. Reading the notice carefully, understanding the deadline, and taking appropriate action before that deadline passes remain the most important steps.
Whether you agree, disagree, or need to make a payment arrangement, responding shows the department that you are aware of the situation and taking it seriously. More options and more control exist at this stage than after enforcement action begins.
