New Mexico Back Taxes: The TRD Gross Receipts Tax Guide (2025)
The short answer: if you owe New Mexico back taxes, the bill almost always comes from the New Mexico Taxation and Revenue Department (TRD) — most often unpaid gross receipts tax (GRT), New Mexico's version of sales tax for businesses. You can usually set up a payment plan, protest a wrong assessment within 90 days, or pursue penalty relief before liens and levies start.
Behind on New Mexico gross receipts tax?
Send us your TRD notice. An experienced tax professional will explain exactly where you stand with the state — and the IRS, if both are involved — free, confidential, and with no pressure.
⏱ Your deadline: you generally have 90 days from the date the TRD mails an assessment to file a written protest. Miss that window and the assessment usually becomes final — which means interest keeps growing and the department can move toward a lien or levy. Act before the 90 days run out.
Why you owe New Mexico back taxes
If you got a notice from the TRD, it usually traces back to one of a few things. You may have filed a gross receipts tax return but didn't pay the full amount. You may have under-reported your receipts. Or you may have stopped filing altogether — common for small business owners, contractors, and the self-employed who fall behind during a slow stretch.
New Mexico is unusual. It doesn't charge a traditional sales tax. Instead it charges gross receipts tax (GRT) on businesses for the privilege of doing business in the state. The combined state and local rate usually runs about 5% to 9% of your total receipts, depending on your location. You can read the official overview on the TRD gross receipts tax page. Most owners collect that tax from customers — but the business is the one legally on the hook to file and pay it. That's why a few missed filings can turn into a real debt fast.
A real-world example of how it adds up
Say you run a small service business in Albuquerque with $200,000 in taxable gross receipts for the year, at a combined rate of about 7.875%. That's roughly $15,750 in gross receipts tax you owe.
Now miss the deadline. New Mexico's late-payment penalty is generally 2% per month, capped at 20% of the tax due — that's up to $3,150 in penalty alone. Interest accrues on top of that at the rate the state sets each quarter. A $15,750 bill can quietly grow past $19,000 before you've done anything about it. That's why early action saves the most money.
What happens if you ignore the TRD
New Mexico collections work a lot like the IRS: automated, patient, and unforgiving of delay. Ignore the notices and the process escalates step by step:
- Notice of assessment — the TRD tells you what it says you owe. Your 90-day protest clock starts here.
- Demand for payment — reminder notices that the balance is due, with penalty and interest still growing.
- Tax lien — the state can file a lien against your business and personal property, which damages credit and clouds any sale or refinance.
- Levy and seizure — once the assessment is final and unpaid, the TRD can levy bank accounts, garnish wages, and seize assets to satisfy the debt.
Unlike a filed return, an unfiled period can stay open far longer. When you never file, there's often no statute of limitations on assessment for that period — so the TRD can reach back further than you'd expect. Filing the missing returns is what starts the clock running in your favor.
First: make sure the assessment is right
Before you pay anything or panic, confirm the number is correct. Log into your account through the state's Taxpayer Access Point (TAP) and compare what the TRD shows with your own records. A few common problems:
- Wrong reporting location. GRT rates vary by address. If your return used the wrong location code, your tax may be off.
- Deductions or exemptions missed. Some receipts qualify for deductions — for example, certain sales for resale. If they weren't claimed, the assessment may be too high.
- Payments that didn't post. Like the IRS, the TRD can cross a recent payment in the mail. Check whether yours was applied to the right period.
If the assessment is wrong, file your written protest within the 90-day window and include your documentation. Don't pay a balance you don't owe and assume the state will fix it later.
If you can't pay in full: your real options
The TRD has more flexibility than its notices suggest. Which path fits depends on your finances and whether all your returns are filed:
- Installment agreement (payment plan). New Mexico lets you pay your balance monthly instead of all at once. You'll generally need to stay current on new filings during the plan. Penalties and interest keep adding up, but an active agreement stops liens and levies from advancing.
- File the missing returns first. If part of your debt is from periods the TRD estimated for you, filing accurate returns often lowers the real number. This is the single biggest lever for many business owners.
- Penalty abatement. If you had reasonable cause — illness, a natural disaster, records lost in a fire — you can ask the department to remove penalties. It won't erase the tax, but it can cut the balance meaningfully.
- Managed audit or voluntary disclosure. If you've been operating without filing, coming forward voluntarily can reduce penalties compared with waiting to get caught.
One warning: anyone promising to settle your New Mexico tax debt for "pennies on the dollar" before reviewing your books is selling you something. Real relief starts with the math, not a sales pitch.
Don't forget the federal side
If you fell behind on New Mexico GRT, there's a good chance you're also behind with the IRS — many business owners owe both at once. The IRS runs its own collection process with its own deadlines and a 10-year collection statute. If you owe both, the fix usually has to be coordinated. Start with setting up an IRS payment plan and, for balances under $50,000, look at a streamlined installment agreement. You can review federal payment options directly at IRS.gov payment plans.
How to respond, step by step
- Read the notice and find the deadline. Note the assessment date — your 90-day protest window runs from there.
- Verify the balance in your TAP account against your own records and GRT returns.
- File any missing returns. Accurate filings often shrink an estimated balance and stop the open-ended assessment clock.
- If the amount is wrong, file a written protest within 90 days with your documentation attached.
- If it's right but you can't pay, request an installment agreement and ask about penalty abatement at the same time.
- If you owe the IRS too, or the balance is large, get a professional review so the state and federal pieces are handled in the right order.
New Mexico back taxes, answered
What is gross receipts tax in New Mexico?
New Mexico doesn't have a traditional sales tax. Instead it charges gross receipts tax (GRT) on businesses for the privilege of doing business in the state. The combined state and local rate usually runs about 5% to 9% of your total receipts. Most owners pass it to customers, but the business is legally responsible for filing and paying it.
How long does New Mexico have to collect back taxes?
Once the TRD makes an assessment, it generally has up to 10 years to collect the debt through liens and levies. If you never filed a return, there is often no statute of limitations on assessment for that period — meaning the TRD can go back further than you'd expect. Filing the missing returns starts the clock.
Can the New Mexico TRD levy my bank account or garnish wages?
Yes. After an assessment becomes final and unpaid, the Taxation and Revenue Department can file a tax lien, levy your business or personal bank accounts, garnish wages, and seize assets. These actions follow the same automated escalation pattern as the IRS, so the safest move is to respond before the assessment becomes final.
Does New Mexico offer a payment plan for back taxes?
Yes. The TRD allows installment agreements that let you pay your balance monthly instead of all at once. You'll usually need to stay current on new filings while you pay. Penalties and interest continue to add up during the plan, but an active agreement stops liens and levies from moving forward.
How do I protest a New Mexico tax assessment?
You generally have 90 days from the date the TRD mails an assessment to file a written protest. Missing that window can make the assessment final and much harder to challenge. If you believe the amount is wrong, file the protest in time and include your records — don't wait and hope the department corrects it.
