New Mexico Notice of Assessment Checklist
A New Mexico Notice of Assessment is a formal letter from the New Mexico Taxation and Revenue Department stating that you owe unpaid taxes and requesting action by a specific deadline. The state sends this notice after determining you have an unpaid tax debt, making it a serious step in the collection process.
Responding to this New Mexico Taxation and Revenue Department collection notice—even if you disagree with what is owed—is important because ignoring it can lead to additional enforcement actions like wage garnishment, bank levies, or property liens. Receiving this notice does not automatically mean these actions have already started, but it does trigger critical deadlines you must observe.
What This Notice Means
The Notice of Assessment tells you that the state has determined you have an unpaid tax debt and is formally demanding payment. This notice represents a collection action—a step the state takes after you have not paid taxes that were assessed or reported to be owed.
Why the State Sent This Notice
The state typically sends a Notice of Assessment when a taxpayer has failed to respond to earlier notices or has not paid an assessed tax debt within the normal timeframe. This can happen after a tax return was filed late, taxes were assessed during an audit, or a payment plan was missed.
What Happens If You Ignore This Notice
When any person neglects or refuses to pay taxes after assessment and demand for payment has been made, a lien automatically exists under New Mexico law. Filing a notice of lien on your property and levying your bank accounts or wages are enforcement actions the department may pursue.
Longer periods of unpaid debt result in the state using more enforcement tools against you. Statutory authority also allows the department to intercept future state tax refunds and apply them toward unpaid tax debts.
What This Notice Does Not Mean
Receiving a Notice of Assessment does not mean wage garnishment, bank levies, or liens have already been placed—it is a demand for payment before those actions typically occur. Tax collection matters are generally civil in New Mexico, so this notice does not mean criminal action is being taken.
Critical Deadline: The 90-Day Protest Period
You must file a written protest within 90 days of the mailing date of the Notice of Assessment if you disagree with the tax amount. Missing this deadline results in the waiver of your protest rights and makes the assessment final.
No extension is available by requesting more time after the 90 days have passed. Payment arrangements can be requested at any time by contacting the department, regardless of protest deadlines.
Checklist: What to Do After Receiving This Notice
Step 1: Read the notice completely
Find and carefully read the entire notice from start to finish. Write down the tax type, the tax period or year involved, the amount owed, and the mailing date of the notice.
Step 2: Verify the information on the notice
Check that the notice shows your correct name, address, and tax identification number. Review the tax period and amount claimed to determine if the information matches your records.
Step 3: Gather your tax records
Collect any documents related to the tax period in question, including the tax return you filed, payment receipts, canceled checks, bank statements, or records of payments you believe you already made. Organize these documents, but do not send them yet until you determine your next step.
Step 4: Determine if you agree or disagree
Ask yourself whether you believe you owe this amount and whether you filed a tax return for this period. Write down your answer and reasoning so you are clear about your position before contacting the state. Your decision here determines whether you will pay, request a payment plan, or file a protest.
Step 5: Contact the department
Look at the notice to find the contact information for the department or the specific unit that sent the letter. Be prepared to provide the notice number, the tax period, and your tax identification number when you call or visit.
Step 6: File a written protest if you disagree
Your protest must include your name and identification number, the tax involved, a summary of the grounds for your protest, evidence supporting each ground, and the relief you are requesting. Mail your protest to the New Mexico Taxation and Revenue Department, Protest Office, P.O. Box 1671, Santa Fe, NM 87504-1671.
The Protest Office will acknowledge your protest and assign someone to handle your case. Remember that you must file within 90 days of the mailing date shown on the notice.
Step 7: Request a payment plan if needed
Contact the department before any deadline expires and request a payment plan if you agree that you owe the tax but cannot pay the full amount. Short-term payment plans allow 12 or fewer months to pay, while installment agreements allow up to 72 months.
Plans longer than 12 months require that a lien be put in place. Making a good-faith payment or requesting a plan shows that you are addressing the debt.
Step 8: Keep records of all communications
Write down the date, time, the person's name, and what was discussed if you speak with someone at the department by phone. Send documents or payments by certified mail and keep the receipt. Keep any papers you are given if you visit in person. These records protect you if disputes arise later.
Step 9: Follow through on agreements
Make payments on time if you agreed to a payment plan. Prepare and send additional information or documents by the deadline given if the department requested them.
Common Mistakes to Avoid
● Missing the 90-day protest deadline without filing a written protest if you disagree with the assessment
● Assuming you can negotiate the assessment amount after the 90-day period has passed without having filed a protest
● Sending a payment to the wrong address or in an unclear way that the department cannot match to your account
