Before the Tax Assessor Comes: Preparing for a Property Reassessment

Before the Tax Assessor Comes: Preparing for a Property Reassessment gives you a clear, step-by-step way to understand what drives your bill, what to verify on your notice, and what to do if the numbers look off.

When your locality reassesses property (annually or every few years), it can mean a higher tax bill if values have risen. Preparing ahead of time is the best way to avoid surprises. By the time the assessor’s notice arrives, it’s often too late to fix errors or gather evidence. Take these steps before the reassessment or

inspection

• Gather Your Documentation: Obtain your current assessment notice and property record card

from the county website or assessor’s office. Review all the details – land size, square footage, number of bathrooms, outbuildings, etc. – and double-check them against reality. Mistakes do happen. As Investopedia notes, many homeowners don’t realize they can simply request the property tax card to verify facts. If the card lists incorrect details (e.g. a non-existent second 4 kitchen, wrong lot size), contact the assessor before reassessment and ask for correction. An accurate record is the foundation of a fair assessment.

• Document Your Home’s Condition: Walk through your property and document any defects or

obsolescence. Take dated photos of things like a cracked driveway, leaky roof, old furnace, or deferred maintenance. If your home has issues (e.g. outdated electrical, termite damage, etc.) that lower its true market value, you’ll want this proof ready. Often the assessor only sees age or external features; pre-documenting problems ensures you have evidence if those flaws are overlooked during a visit.

• Note Recent Upgrades (Carefully): If you made improvements, keep records (permits, receipts) of

what was done and when. Major improvements (like adding a bathroom or finishing a basement) will likely increase your assessed value. If you’re in a tight tax situation, it might even make sense to postpone non-essential upgrades until after the assessment. (On the other hand, necessary work should be done – but document it so you can claim any eligible deductions.) Remember, as Kiplinger points out, major renovations generally boost your home’s assessed value. Plan projects with tax timing in mind.

• Compare with Neighbors Early: Well before tax time, casually check the tax assessments and

recent sale prices of similar homes on your street or subdivision. This gives you a baseline of what others pay. If a neighbor’s house (with the same bedrooms, size, lot) is assessed significantly lower, mark that discrepancy. This kind of “pre-audit” search can save time if you later need to appeal; keep a file of any interesting finds.

• Attend Open Houses or Let Assessors In (Optional): Many assessors schedule property visits, but

it’s usually optional for single-family homes. However, being present during an assessment can be an advantage – you can point out repairs or clarify facts. If you choose to allow an inspection, be open but also guide the assessor: highlight any areas of concern and remind them of features not immediately visible (like a crawlspace needing work). ACPA (Appraisal Institute) suggests homeowners consider accompanying assessors to prevent misunderstandings.

• Know Your Local Process and Deadlines: Research your town’s reassessment schedule. Some areas

reassess every year, others every 2-4 years. California, for example, does a full reassessment on ownership changes, while Texas homeowners get notices yearly (with appeals then due). Mark your calendar: when will notices go out? What are the deadlines to formally protest? Being aware means you won’t miss your chance.

• Budget for the Possibility: If property values have surged in your area (as they have in much of

2025), even an accurate assessment could hike your taxes. Check local news or Tax Foundation reports for state trends. For example, if home prices jumped 10%, expect higher bills unless rates fall. Financially prepare by putting aside some funds so you’re not caught off-guard.

• Leverage Professional Insight: If you own multiple rental or investment properties, consider a pre-

assessment consultation. A tax consultant can pre-emptively spot weak points in your assessment. For a single-family homeowner, using a tool like ProptaxHelper to simulate different assessments based on comps can give you a “heads up” on what to expect. 5 By getting organized now – verifying your home’s data, documenting conditions, and understanding your rights – you’ll be far better positioned when reassessment time arrives. As Bankrate advises, start with “a careful review” of any notice and gather evidence before filing a protest. Think of it like preparing for an exam: the more you study your property’s facts in advance, the stronger your case will be if you must

appeal. And remember: after a reassessment, you’ll have a limited window to challenge the new value. Don’t wait until the last minute to learn the process. Use ProptaxHelper now to check your current assessment against recent sales – a free second opinion before the assessor comes. Being proactive can mean the difference between a manageable tax bill and a painful surprise.
