New Mexico Property Tax
Savings by County
A practical, per-county look at the real property tax breaks available to homeowners and buyers across the Albuquerque metro area.
How property taxes work for homeowners across Albuquerque, Rio Rancho, Corrales, Placitas, Los Ranchos de Albuquerque, North Albuquerque Acres, High Desert, Glenwood Hills, Sandia Heights, Four Hills, and Volterra, in one minute.
-
Taxes are calculated on one-third of your home's value (the assessed value), multiplied by your area's mill rate per $1,000. In Bernalillo County the 2025 certified composite rate is about 42.258 mills, roughly $5,634 a year on a $400,000 home before exemptions, and the exact rate varies by taxing district.
-
Head of Family exemption: $2,000 off your taxable value, but only if you apply to the county assessor.
-
Veterans exemption: $10,000 off your taxable value for honorably discharged veterans (HB 47, 2025), and 100% disabled veterans pay no property tax, but you must apply.
-
Age 65 and older: a valuation freeze may cap your taxes, income limits apply, and low-income seniors or disabled owners may also qualify for the state rebate, but all require filing.
-
Solar panels: the system's value is exempt from property tax, but you have to claim it with the assessor.
-
Every one of these requires an application, and many eligible homeowners never file, so they quietly overpay every year.
-
Most claims must be filed within 30 days of the Notice of Value, which typically arrives at the end of April. Check yours.

How Property Taxes Really Work in Bernalillo County
The plain-English version, no jargon required.
How Your Tax Bill Is Calculated
Start with the two numbers on your Notice of Value, because mixing them up is where most of the confusion begins. The county assessor sets your home's market value, which is meant to reflect what the property would sell for. You are not taxed on that full number. New Mexico taxes residential property on one-third of it, and that smaller figure is the assessed value, also called the taxable value. Your bill is built on the assessed value, not the full market value.
The formula is simple once you know the two pieces:
The Formula
Taxes due = (home value × 1/3) × mill rate ÷ 1,000
What a Mill Is
One mill = $1 of tax for every $1,000 of assessed value
The 3% cap. For a home you own and live in, the assessed value can rise by no more than 3% in a year. That cap resets when you buy the home, add square footage, or ownership changes, and the value moves to current market value. It is why a new buyer's bill can jump even in a neighborhood where prices have been steady: the purchase resets the assessed value, so a full reappraisal lands all at once.
Worked Example
A $400,000 Home in Albuquerque
Example numbers, clearly labeled, matched to Bernalillo County's verified 2025 composite residential rate.
Market value: $400,000
What the county assessor values the property at. You are not taxed on this number.
Assessed value: $400,000 × 1/3 = $133,333
Residential property is taxed on one-third of the market value. This is the taxable base.
Mill rate: about 42.258 mills
Bernalillo County's 2025 certified composite residential rate, before your property's district adjustments.
Before exemptions: $133,333 × 42.258 ÷ 1,000 = about $5,634 per year
The baseline bill if no exemptions are on file.
Head of Family exemption: $133,333 - $2,000 = $131,333
Exemptions are applied to the taxable value first, before the mill rate.
With the exemption: $131,333 × 42.258 ÷ 1,000 = about $5,550 per year
Claiming that one exemption saves roughly $84 a year on this example.
The honest caveat: your property's exact mill rate depends on its taxing district. The City of Albuquerque versus unincorporated areas, your school district, and the special districts serving the address each add their own share, so the real number varies from home to home. The county treasurer's certified rate chart is the source for your specific address, and this example uses the verified composite rate for the county.
Checking your Notice of Value and your actual bill against this formula is the first step to knowing whether you are paying the right amount. When we evaluate a home together, Nysha can pull the property's tax history, so you see the assessed value, the exemptions on file, and what a new owner should realistically expect before you make an offer.
The Savings Programs Most Owners Never Claim
Here is the blunt truth: none of these savings are automatic. Every one of them requires an application with the county assessor, most claims are due within 30 days of the Notice of Value (typically mailed at the end of April), and a large share of eligible owners never file. They quietly overpay, every single year, usually because nobody told them to check.
Head of Family Exemption
$2,000 off the taxable value for a qualifying resident homeowner, one per household. Apply with the Bernalillo County Assessor.
If you own and live in your home, check this first.
Veterans Exemption
$10,000 off the taxable value for an honorably discharged veteran (or unmarried surviving spouse) with at least 90 consecutive days of service other than training, who is a legal New Mexico resident. Raised from $4,000 by HB 47 in 2025, and veterans with a 100 percent service-connected disability are fully exempt from property tax.
If you served, do not skip this one.
Age 65+ Valuation Freeze
Qualifying homeowners 65 and older can freeze the taxable value of their home, which caps how much that number can grow. Income limits apply, so confirm the current limit with the assessor before you file.
It protects long-term owners from sharp reassessments.
Low-Income Senior and Disabled Rebate
Eligible low-income seniors and disabled homeowners can claim the state Property Tax Rebate, filed on Schedule PIT-RC with their New Mexico state income tax return. Confirm the current income limits with the NM Taxation & Revenue Department at tax.newmexico.gov.
It is claimed on your state return, not at the county office.
Solar Energy Exemption
The value of a residential solar energy system is exempt from property tax, but you have to claim it with the assessor. If you are planning to install, contact the assessor first so the paperwork is in place.
Ask before install, then claim it after.
The common thread: every one of these requires filing, millions of dollars of exemptions go unclaimed every year, and checking whether you qualify takes about a minute. Nysha can walk you through what applies when you buy, sell, or simply want to know if you are overpaying.
Why Your Bill Can Go Up Even When You Hear the Rate Dropped
Two numbers, not one. Your bill is the rate times the assessed value, two separate figures that both change every year. You only ever see the outcome, so it is easy to mistake which part moved.
The headline can lie to you. Officials sometimes announce a mill rate decrease, and Bernalillo County's residential mill rate dropped in 2024 and again in 2025. But if your home's assessed value rose the same year, the increase can eat the savings and then some. This is the tax lightning new owners feel: your value resets to market when you buy, so a full year of increase lands all at once.
What keeps it in check. Yield control moderates how much revenue can grow year to year, but a rising valuation, a new taxing district, or a voter-approved levy can still push your bill up.
The practical takeaway. Do not judge your bill by the headlines. Read the Notice of Value, check the assessed value against what your home is really worth, and if the value looks high, you have the right to protest by the county deadline, typically April 30. Confirm the exact date with your assessor.
That is the honest lay of the land, in plain English. Not sure which pieces apply to you? Take the quick quiz above, it takes about a minute. Want the full picture for the metro?

Applying for exemptions like Head of Family can reduce the taxable value your bill is based on, which lowers what you pay each year.
The part most homeowners miss
Bernalillo County and the state of New Mexico both run exemption and relief programs, and every one of them has to be applied for. Nothing is automatic, and the county does not apply a program until you file for it.
That means many homeowners qualify for something they have never filed. They quietly pay more than they need to, usually because nobody ever told them to check.
Nysha Lynn Livingston is happy to check what is on your record and what you might qualify for, at no cost and with no obligation.
This estimate is approximate. Exact amounts depend on your property's tax district and exemptions. Confirm with the Bernalillo County Assessor's Office.

Frequently Asked Questions
A few of the questions homeowners ask most often about assessed value, exemptions, and the county process, answered in plain English.
What does assessed value mean?
It is the number your tax bill is based on. In New Mexico, residential property is assessed at one-third of its market value, so a home the county values at $300,000 has an assessed value of $100,000. The county multiplies that taxable value by your area's mill rate and divides by 1,000 to arrive at your bill, before any exemptions are applied.
How do I check if I'm already receiving an exemption?
Your annual assessment notice and your property tax bill both show which exemptions are applied to your property, with entries like Head of Family or Veterans Exemption. If you are not sure what you are looking at, you can ask Nysha to pull your record from the county and walk you through it.
When are property taxes due in Bernalillo County?
Taxes are billed in two equal installments. The first half is typically due November 10 and the second half April 10, with the county treasurer mailing the bill ahead of the first due date. Confirm the exact dates for your account with the Bernalillo County Treasurer.
Can I appeal my assessed value?
Yes. If you believe your assessed value is too high, you can file a valuation protest with the county assessor by the deadline the county publishes for your Notice of Value, typically within 30 days of the mailing. Missing the window forfeits that year's protest, so confirm the exact date with the assessor's office.
Where do I find my assessed value?
On your Notice of Value, which the county mails each year (usually at the end of April), and on your property tax bill. You can also look it up any time using the Bernalillo County Assessor's online property search, which shows the assessed value and any exemptions on file.
Do exemptions need to be re-applied every year?
Most exemptions, like Head of Family and the veterans exemption, stay in place once approved as long as you remain eligible. The low-income senior and disabled rebate is claimed each year through your state income tax return. The best habit is to check your Notice of Value every year and confirm the exemptions you expect are still listed.

Property Taxes Are Set Locally
In New Mexico, property taxes are set at the local county level. The state defines how value is assessed and which exemptions exist, but the mill levy applied to your home is a county-by-county combination of county, city, school, and special district rates. That means what you save depends on where your home sits, and the programs you can claim depend on the county that assesses it.
This guide covers the statewide savings every New Mexico homeowner should know, then breaks down what is happening in the four counties that make up most of the Albuquerque metro market: Bernalillo, Sandoval, Valencia, and Santa Fe. Figures were compiled from the New Mexico Taxation & Revenue Department, each county assessor, and the annual rate certifications published by the NM Department of Finance and Administration. Amounts and limits change, so use this as a starting point and confirm the current details with the county office before acting.
How Property Tax Is Calculated in New Mexico
Every county in New Mexico applies the same statutory formula. Residential property is assessed at one-third (33.33%) of its full market value, and the mill rate is applied to the net taxable value that results:
Step 1
Full Value × 1/3 = Assessed Value
Step 2
Assessed Value × Mill Rate ÷ 1,000 = Taxes Due
Put simply, your tax bill equals net taxable value times the mill rate, divided by 1,000. A mill is one dollar of tax for every $1,000 of net taxable value, so a rate of 42.258 mills means about $42.26 in tax per $1,000 of taxable value.
Residential assessed values are capped at a 3% annual increase, with exceptions for a change of ownership, new construction, and added square footage. A new owner is assessed at market value, so a recent purchase can reset the assessed figure.
The Notice of Value is typically mailed at the end of April each year. Exemption application deadlines are generally 30 days from that mailing, and valuation protests follow the county's published deadline. Confirm the exact dates with your county assessor.

How These Numbers Were Verified
Mill rates on this page are sourced from the certified rates affirmed by the New Mexico Department of Finance and Administration and from each county assessor's or treasurer's published rate charts. Residential property is assessed at one-third of value statewide, and the formula shown above was used for every example.
The figures on this page were reviewed in September 2026 and can change annually as counties certify new rates and the Legislature adjusts exemption law. Verify the current numbers with the Bernalillo County Assessor, the Bernalillo County Treasurer, or the New Mexico Taxation & Revenue Department before relying on them for a specific property.
Statewide Savings Every Homeowner Should Know
One statewide base rule applies everywhere: residential property in New Mexico is assessed at one-third of its market value, and most exemptions reduce that assessed figure before the mill levy is applied. These six statewide savings are available to qualifying homeowners in every county listed below.
Head of Family Exemption
Removes $2,000 from the assessed (taxable) value of your primary residence before the mill levy applies. One claim per household: a married person, widow or widower, a single person, or a head of household who supports a related person can qualify. Apply once with your county assessor, and the exemption stays in place while you remain eligible.
Senior (65+) Property Tax Freeze
Qualifying homeowners who are 65 or older (or disabled) can freeze the taxable value of their primary residence. The freeze caps the assessed value, not the tax bill, so mill rate increases still apply. Income limits apply and adjust annually, so confirm the current limit with your county assessor or tax.newmexico.gov before filing the Application for Limitation on Increase in Value.
Veterans and Disabled Persons Exemptions
Honorably discharged veterans who are legal New Mexico residents qualify for a $10,000 reduction in the taxable value of their primary residence, raised from $4,000 by HB 47 in 2025. The exemption requires at least 90 consecutive days of service (other than training) and also covers an unmarried surviving spouse. A 100 percent service-connected disabled veteran keeps a full exemption on the primary residence. File with your county assessor.
Low-Income Senior and Disabled Rebate
Under the Property Tax Assistance Act, homeowners 65 or older (and disabled homeowners) may qualify for the state Property Tax Rebate on their principal residence. Claim it on Schedule PIT-RC filed with your New Mexico income tax return through the New Mexico Taxation and Revenue Department. Income limits apply and change over time, so confirm the current limit with your county assessor or tax.newmexico.gov.
Solar and Renewable Energy Exemption
New Mexico exempts residential solar energy systems from property tax up to the allowed value, and qualifying wind, hydro, and geothermal systems can qualify as well. Contact your county assessor before installing to make sure you claim the exemption, and keep your installation documentation so the savings is easy to capture at the county level.
Annual Valuation and Exemption Deadlines
The Notice of Value is typically mailed at the end of April each year. Exemption application deadlines are generally 30 days from that mailing, and valuation protests follow the county's published deadline. Missing the window forfeits that year's protest, so mark the date on your notice and confirm the exact deadline with your county assessor.
Bernalillo County (Albuquerque)
Verified Against Official County Sources
Verified against official county sources. The 2025 tax year composite certified mill rate for Bernalillo County is approximately 42.258 mills, or about $42.26 per $1,000 of net taxable value. That composite combines the county, municipal, school district, and special district levies affirmed by the New Mexico Department of Finance and Administration. The actual rate for a given property varies by taxing district within the county, such as the City of Albuquerque versus unincorporated areas, so use the formula on this page and look up your area's exact rate on the county treasurer's certified rate chart.
Worked example, using clearly labeled example numbers: a $400,000 Albuquerque home is assessed at one-third of value, or $133,333. Before exemptions, at roughly 42.258 mills, that works out to about $5,634 per year. Step by step: $400,000 divided by 3 equals $133,333 in assessed value; $133,333 times 42.258 equals about $5,634,400; dividing by 1,000 gives about $5,634 per year. The exact bill depends on the property's taxing district and the exemptions on file, so this example is not a quote for any specific property.
Verified exemptions come from the Bernalillo County Assessor's Office (bernco.gov). The Head of Family exemption takes $2,000 off the taxable value for qualifying resident homeowners. The Veterans exemption takes $10,000 off the taxable value for any honorably discharged veteran (or unmarried surviving spouse) with at least 90 consecutive days of service (other than training) who is a legal New Mexico resident, raised from $4,000 by HB 47 in 2025. Veterans with a 100 percent service-connected disability are fully exempt from property tax.
A senior (65+) valuation freeze is available with income limits, and low-income seniors and disabled homeowners may also qualify for the state Property Tax Rebate through Schedule PIT-RC with the New Mexico Taxation and Revenue Department. Income limits apply to those programs and are not stated here, so confirm the current limit with the assessor or tax.newmexico.gov.
New Mexico exempts residential solar energy systems from property tax up to the allowed value. Contact the Bernalillo County Assessor before installing to make sure you claim it. The assessor also accepts Head of Family, veteran, senior freeze, and valuation protest filings, and the treasurer's office handles current tax payments and the certified rate chart.

Sandoval County (Rio Rancho, Corrales, Placitas)
Sandoval County rates vary by taxing district. County, municipal, school district, and special district levies are combined into one bill, so a home in Rio Rancho carries a different total rate than a home in Corrales or Placitas even though all three sit in Sandoval County. The county assessor publishes the certified rates for each district and a property tax calendar on its website, and the treasurer's office can confirm the rate that applies to a specific parcel.
As elsewhere in the state, residential property is assessed at one-third of market value, and qualifying exemptions lower the net taxable base. Your tax bill equals net taxable value times the district mill rate, divided by 1,000. Confirm the current rate for your district with the Sandoval County Assessor, and confirm valuation and protest dates on the county's published tax calendar.
The Sandoval County assessor handles Head of Family exemption applications, the senior value freeze, veteran and solar exemptions, and valuation protests, and the treasurer's office accepts tax payments and provides account lookup. Rio Rancho, Corrales, and Placitas each have their own municipal levies, so check the district codes on the property's tax bill to confirm the rate that applies.
County Contacts and Records
Valencia County (Los Lunas, Belen)
Valencia County mill rates vary by municipality and school district, so the total rate on a home in Los Lunas can differ from one in Belen. Rates are certified annually by the New Mexico Department of Finance and Administration, and the county treasurer's online tax account search shows the current charges for a specific parcel. Use the formula on this page and confirm the current rate with the county assessor or treasurer before budgeting.
Residential property is assessed at one-third of market value statewide, and Valencia County valuations follow the same statutory base. The county's online property search (EagleWeb) shows current assessed value and exemption status for any parcel, which is a useful starting point when you are evaluating a home.
Rates and exemptions change each year, so confirm the current figures for the specific property through the county assessor and the treasurer's tax account search before relying on an estimate.

Santa Fe County (Edgewood)
Santa Fe County residential mill rates vary by district code. The assessor publishes a mill rate table by district, and the parcel's location and district codes determine which rate applies. Edgewood straddles county lines, so a portion of the community is assessed by Sandoval or Bernalillo counties. Confirm the current rate for the specific property with the Santa Fe County Assessor or Treasurer.
Residential property is assessed at one-third of market value, and your tax bill equals net taxable value times the district mill rate, divided by 1,000. Santa Fe County's assessor publishes a help guide explaining assessed value, exemptions, and the annual valuation cycle, and the county posts its official mill rates by district for review.
Santa Fe County residents may qualify for the low-income senior and disabled property tax rebate. Income limits apply, so confirm the current limit with the county assessor or tax.newmexico.gov. The assessor accepts exemption applications and valuation protests, and the county provides an online property map, a tax estimator, and online tax payment.

What Buyers Should Ask Before Buying
Property taxes follow the property, and they are one of the most predictable ownership costs you can verify before you make an offer. These are the questions to ask during your search, no matter which county you are buying in.
How do I check a property's current assessed value and tax history?
Start with the county assessor's online property search, which shows the current assessed value, any exemptions on file, and the parcel's district codes. Then check the county treasurer's tax lookup for current charges and payment history. Each county section on this page links both offices.
Should I ask the listing agent for tax records before making an offer?
Yes. Ask for the last two years of property tax statements. Two years shows whether the home was recently reassessed and whether the current owner carries exemptions such as Head of Family, veteran, senior freeze, or solar. Most exemptions attach to the owner, not the property, so a new buyer typically needs to reapply after closing, and the first bill you receive may differ from what the seller paid.
How should a new buyer budget for property taxes?
Property tax is charged on assessed value, which for residential property is one-third of market value minus qualifying exemptions, and the mill levy varies by county, city, school district, and special district. The formula on this page works in every metro county, but the rate that applies depends on the property's district codes. The seller's current statements and your lender's escrow estimate are useful starting points, and the county treasurer can confirm the expected bill for the specific property.
Which property tax exemptions transfer to a new buyer?
Most exemptions do not transfer automatically. Head of Family, veteran, senior freeze, and low-income rebate claims each require an owner application filed with the county assessor. The solar energy exemption stays with the system and must be claimed by the owner. Ask the seller to document any exemption currently on the property and plan to file the correct claims after you close.
