Own acreage in Corrales or nearby Los Ranchos and wondering if your land could be taxed as agricultural? If you actively produce crops, hay, or graze livestock, an ag valuation might lower your property tax bill. The process is specific, but with the right records and a clear plan, you can put your land to work and protect your bottom line. In this guide, you’ll learn what counts as bona fide agricultural use in New Mexico, how to apply in Sandoval County, and how to keep your status over time. Let’s dive in.
Ag valuation basics
Agricultural valuation is a property tax classification that values qualifying land based on agricultural use instead of full market value. When approved, the assessed value of the qualifying acreage is generally lower than if it were valued as residential land. That can reduce your tax burden and help keep small farms and ranches viable.
If you later change the use of the land, the county may assess back taxes, often called rollback taxes, to recapture the prior tax benefit. Before you subdivide, build additional homes, or stop production, you’ll want to understand the implications.
For specifics on rules and procedures, confirm details with the Sandoval County Assessor and the New Mexico Taxation and Revenue Department’s Property Tax Division.
Who qualifies
New Mexico counties look for bona fide agricultural use, meaning sustained, active production with a commercial intent. Corrales and Los Ranchos have many small-acreage properties, and some do qualify when the use is consistent and documented.
Qualifying uses
- Crop and orchard production, including hay and vineyards
- Pasturage and grazing for livestock
- Commercial nurseries and certain horticultural operations
- Greenhouses or tree farms that operate as genuine ag enterprises
What usually does not qualify
- Hobby gardens or occasional harvests for personal use
- Keeping horses for personal recreation without a commercial operation
Equine operations in particular receive close scrutiny. Commercial boarding, breeding for sale, riding programs, or hay production tied to the operation can strengthen your case. Personal riding on its own typically does not meet the standard.
Small-acreage intensity
In Corrales and Los Ranchos, parcels are often small to mid-sized. Size alone does not decide eligibility. Assessors consider how intensively and consistently you use the land for production, and whether you can show commercial activity. A few fruit trees without sales usually won’t qualify, while a well-documented market garden with regular customers might.
What to document
Strong documentation is the key to approval and to keeping your classification over time. Aim for multiple seasons of consistent records.
Production and income
- Sales receipts and invoices for crops, hay, nursery stock, or livestock
- Farm income on federal tax forms such as Schedule F, or clear bookkeeping showing agricultural receipts
- Grazing receipts, stocking records, or CSA subscriber lists
Maps and photos
- Parcel map showing the acreage you want classified
- Aerial images and on-the-ground photos that show fields, pastures, fencing, irrigation, barns, and production areas
Leases and third-party records
- Grazing leases and sales contracts
- USDA FSA and NRCS records, conservation plans, or soil capability maps
- Letters from extension agents or veterinarians that verify herd inventory or operational details
Water and irrigation proof
- Acequia membership information and ditch maps
- Water rights or permits and well documentation
In Corrales, acequia systems and irrigation access are especially important for orchards and market gardens. If you irrigate, make sure you can document it.
How to apply in Sandoval County
The county manages applications, site inspections, and decisions. Processes and deadlines can change, so verify current steps with the Sandoval County Assessor.
Step-by-step process
Prepare your file
- Gather 12 to 36 months of production records if possible. Include receipts, invoices, and Schedule F or bookkeeping.
- Assemble parcel maps, aerial images, and photos of active fields and infrastructure.
- Collect leases and any FSA/NRCS or extension documentation.
- Draft a one-page summary of your operation: acreage in active use, what you produce, livestock numbers, and typical annual output or sales.
Submit the application
- Request the agricultural valuation application from the Sandoval County Assessor.
- File the application with your documentation. Provide clear contact information.
County review and inspection
- Assessor staff review your records and typically schedule a site visit to confirm use and acreage.
- Respond quickly to any requests for more information.
Decision and notice
- You’ll receive an approval or denial. If approved, the ag valuation is applied to qualifying acreage for the applicable tax year.
- If denied, the notice should explain why and outline next steps.
Appeal if needed
- If you disagree with the decision or acreage, you can appeal to the county Board of Equalization within the allowed period. Further appeals may go to the state or district court per New Mexico law.
Timelines and expectations
- Start early. Build a record over multiple seasons before you apply.
- Many counties set an annual filing deadline early in the year. Confirm the cutoff and whether late applications are accepted.
- Reviews and inspections can take weeks to a few months, depending on season and workload.
- Approvals typically apply to the tax year indicated on the application. Retrospective relief is limited.
Keep your ag status
Once granted, some counties verify on a schedule or audit periodically. Others keep the classification until the use changes or ownership transfers.
Maintain records annually
- Save receipts, production logs, and updated maps each year.
- Keep photo documentation of planting, grazing, and harvesting cycles.
Notify the assessor of changes
- Report changes like subdividing, development, or a switch from irrigated pasture to non-ag use.
- If you build a house or add non-ag structures, only the portion of land still in agricultural use may remain classified.
Understand rollback taxes
If you convert land from ag use to non-ag use, the county may assess rollback or change-of-use taxes. This can include the difference between prior taxes paid under ag valuation and taxes that would have been due at market value, plus interest and possible penalties, for a specified look-back period. Discuss potential back taxes before you change how the land is used.
Corrales and Los Ranchos tips
Prioritize water and acequias
Irrigation access supports orchard yields and market garden productivity. Document your acequia participation, ditch cleaning contributions where applicable, and water rights.
Focus on repeat sales
Regular farm stand sales, CSA subscriptions, or wholesale accounts show commercial intent. Keep clean records and consider basic bookkeeping software to track income and expenses tied to production.
Be clear with equine operations
Personal horse use usually does not qualify. If your operation includes boarding, breeding for sale, or riding programs, maintain contracts and receipts that show it is a bona fide business.
Plan before subdividing
Subdivision, new home sites, or long idle periods can trigger reclassification and potential back taxes. Talk with the assessor and your tax professional before making changes.
Owner checklist
Before you apply
- Gather 1 to 3 years of receipts, invoices, and production logs
- Compile Schedule F or other clear agricultural income records, if available
- Map the acreage used for production and print current aerial photos
- Collect leases, sales contracts, and CSA or farmers market records
- Assemble FSA/NRCS or extension documentation
- Document irrigation: acequia membership, water rights, and well permits
When you apply
- File the Sandoval County agricultural valuation application with a one-page operation summary
- Include maps, photos, sales records, leases, and third-party documentation
- Provide access information and request an inspection
After approval
- Keep yearly records and seasonal photos
- Respond to assessor inquiries and audits
- Notify the assessor promptly about any change in use
Common mistakes to avoid
- Applying with only a single season of production receipts
- Relying on hobby gardens or personal horse use without commercial activity
- Failing to map and quantify the exact acreage in active production
- Ignoring inspection requests or missing appeal deadlines
- Subdividing or changing use without first checking rollback implications
When to get advice
Because rules, forms, and deadlines can change, confirm current guidance with the Sandoval County Assessor. For state-level procedures, consult the New Mexico Taxation and Revenue Department’s Property Tax Division. FSA and NRCS can provide helpful records and maps, and NMSU Cooperative Extension is a good resource for small-acreage production and recordkeeping best practices. If you are considering development or a significant change in use, speak with a tax professional or attorney about potential rollback exposure.
A thoughtful plan, clear documentation, and timely communication with the assessor can make ag valuation attainable for many Corrales and Los Ranchos properties. If you are buying or selling acreage, understanding this classification can also shape negotiations and long-term costs.
