When Are Property Taxes Reassessed — Avoid Surprises

Property tax reassessment cycles range from yearly to every 10 years by state. Home sales, renovations, and new builds can trigger changes outside the normal cycle. Learn how often reassessments happen, what causes increases, and how to prepare to appeal.

Key Takeaways

  • **Georgia reviews property values every year**: Unlike states with multi-year reappraisal cycles, Georgia counties assess fair market value annually as of January 1 — there is no single "reassessment year" to wait for.
  • **Reassessment cycles vary dramatically by state**: From annual reviews in 27 states to 10-year cycles in Rhode Island, with most states falling between 1 and 6 years.
  • **Sales, permits, and renovations trigger reassessment outside normal cycles**: Even in low-frequency states, a purchase, new construction, or major remodel can reset your assessed value immediately.
  • **Values can change between major reappraisals**: Many jurisdictions apply statistical updates using market data in off-cycle years, so your assessment may rise even without a formal countywide reappraisal.
  • **Check your property record card annually**: Errors in square footage, bedroom count, or condition grade can inflate your value — verify the county's data before each notice arrives.

# How Often Are Property Taxes Reassessed? State-by-State Guide

If you're trying to figure out how often property taxes are reassessed, you're usually asking one of two things:

1) "How often can my county change my home's value?" 2) "When do the big jumps happen?"

The tricky part: "reassessed" means different things in different places. Some jurisdictions update values every year. Others do a full "reappraisal" on a multi-year cycle, then use lighter-weight adjustments in between. And a few systems (like California's) treat sales and major construction as the primary trigger.

This guide clears up the terminology, shows the most common reassessment cycles by state, and gives you a simple way to find your exact schedule — plus a Georgia-specific breakdown.

Summary

What "reassessed" can mean (and why it matters)

Most homeowners experience property value changes in three different "modes":

1) Annual assessment updates

Your assessor updates the assessment roll each year. This may include:

Even if your county only does a full reappraisal every few years, many jurisdictions still adjust values in between to keep up with the market. (NCSL property tax overview PDF)

2) A scheduled reappraisal (revaluation) cycle

This is the "big reset" people usually mean. A countywide reappraisal typically involves re-modeling values across the county and may include physical reviews/field work.

Cycles vary widely (from 1 year to 10 years in commonly cited references). (NCSL property tax overview PDF)

3) Event-triggered changes (sale, major renovation, new construction)

Some states or local systems reassess (or "capture" value) when:

In places with assessment limits, the trigger matters as much as the cycle.

Georgia: annual review (plus countywide digest updates as needed)

Georgia is a good example of why definitions matter.

So if you live in Georgia, the most practical answer is: your value can be reviewed every year — but the biggest changes often happen when the county makes broader digest adjustments and your neighborhood's market data shifts.

What to take away:

State-by-state reassessment cycles (common reappraisal cycles)

The list below reflects a commonly cited set of real property appraisal cycles by state compiled in a national property tax overview. In plain English: this is a useful "starting map," but your county can still have its own calendar, and many states also adjust values between major reappraisals. (NCSL property tax overview PDF)

Georgia note: Georgia values can be reviewed annually (fair market value as of Jan 1), even though "cycle" references often describe broader countywide reappraisal patterns. For homeowners, the day-to-day reality is annual review. (GA DOR property tax FAQ) * Pennsylvania note: Local practice can be uneven; some counties go long stretches between countywide reassessments, even though assessments and equalization concepts exist. Always verify your county's last/next reassessment.

How to find your reassessment timing (fast)

You don't need to guess. Use this checklist:

1) Find your county assessor / property appraiser website. Search: "<County> <State> reappraisal schedule" or "reassessment year."

2) Look up your property record card (PRC). Many counties list a "last reappraisal year" or show the year built, additions, and effective date of value changes.

3) See if your state publishes county schedules. Some states make this very easy: - North Carolina posts county reappraisal schedules. (NC DOR reappraisal schedules) - Tennessee posts a reappraisal schedule by county (last reappraisal / next reappraisal). (TN Comptroller reappraisal schedule)

4) If you're in Ohio, learn the "reappraisal + update" rhythm. Ohio counties reappraise on a six-year cycle, with an update in between. (Ohio reappraisal and triennial update)

5) Call and ask one question: "What was the last countywide reappraisal year, and what's the next one for my parcel?" (If they reappraise in phases, ask which area/region you're in.)

What triggers reassessment outside the normal cycle?

Even in a "low-frequency" state, these are the most common triggers:

Important nuance: some systems are designed so your taxable value can be "limited" year-to-year until a trigger happens. That's why two neighbors with similar homes can have very different taxable values.

How to prepare for reassessment (so you're not blindsided)

If you want fewer surprises, focus on the inputs assessors actually use:

Frequently Asked Questions

Are property taxes reassessed every year?
In many places, values are reviewed or updated annually even if the county only does a major reappraisal every few years. Many jurisdictions also adjust values between reappraisals using market data methods.
Does buying a house trigger a reassessment?
Often, yes — especially in states where assessed value resets at sale or where assessment limits exist. California is the headline example where a change in ownership is a primary reassessment trigger.
How often does Georgia reassess property taxes?
Georgia counties establish fair market value as of January 1 each year and review values annually. There isn't one statewide revaluation schedule, so your value can change year to year based on sales data and county digest review.
What if my county hasn't reassessed in a long time?
When a county finally does a major reappraisal, increases can feel sudden because multiple years of market change get caught up at once. That's when checking your property record and comparables becomes especially important.
If my value goes up after reassessment, can I appeal?
Usually, yes — but deadlines and procedures are local and can be short. Your assessment notice or assessor website will tell you the appeal window and what evidence they accept.
Can a home renovation trigger a property tax reassessment?
Yes. Permits for additions, finished basements, or major remodels often prompt the assessor to update your property's characteristics and value. Even smaller projects can trigger a review if they change livable square footage or quality grade.
How do I find out when my county's next reassessment is?
Search your county assessor's website for the reappraisal schedule, or call and ask for the last and next countywide reappraisal year. Many states also publish county-by-county schedules online.
