What Triggers a Property Tax Reassessment? Key Events That Can Raise Your Taxes
Property taxes are one of the most significant ongoing costs for homeowners, real estate investors, and small businesses alike. While most people expect gradual increases over time, a property tax reassessment can lead to a sudden spike in what you owe.
So, what triggers a property tax reassessment—and how can you prepare for it?
At Hogan CPA Financial Services, we help property owners understand the factors that may cause a reassessment and how to manage the financial impact through proactive planning.
What Is a Property Tax Reassessment?
A property tax reassessment is when your local taxing authority (typically a county or municipality) re-evaluates your property’s assessed value, which directly affects the amount of property tax you owe.
This reassessment can be routine—as part of a scheduled cycle—or it can be triggered by specific events related to your property or its ownership.
Common Triggers for a Property Tax Reassessment
1. Sale or Transfer of Property
When you buy or sell real estate, many states automatically trigger a reassessment to reflect the market value of the transaction. This means your tax bill could increase significantly if the property was previously assessed at a lower value.
2. Major Renovations or Improvements
Upgrades that increase your property’s market value—like adding a pool, building an addition, or finishing a basement—can lead to reassessment. Local assessors may flag your property through permit applications or post-construction inspections.
Tip: Cosmetic improvements (e.g., new paint, landscaping) generally don’t trigger reassessment unless they significantly change the home’s structure or function.
3. New Construction
If you build a home or commercial structure from the ground up, it will typically be assessed upon completion. The same applies to substantial commercial renovations or the repurposing of space.
4. Expired Tax Abatement or Incentive
Many real estate owners benefit from temporary tax abatements, especially in urban redevelopment areas. Once these expire, your property returns to full taxable value—often resulting in a sharp increase.
If you’re unsure how this applies to your portfolio, working with a real estate CPA who specializes in tax planning can help you prepare for what’s ahead.
5. Re-Zoning or Land Use Changes
A shift in how your property is zoned—such as from residential to mixed-use or commercial—can impact its assessed value. Similarly, nearby development may influence how your property is valued relative to market activity.
6. Periodic County or Citywide Reassessments
Some jurisdictions reassess all properties on a fixed schedule (every 3–5 years). Others do it less frequently, relying on statistical models or partial assessments. Keep an eye on local reassessment notices and timelines.
Can a Property Decrease in Value and Be Reassessed Lower?
Yes. If your property value declines—due to market shifts, structural damage, or external factors—you may be eligible for a reduction in assessed value. This is typically done by filing an appeal or requesting a reassessment through your county’s tax office.
How to Prepare for a Reassessment
- Track improvements and permits carefully
- Document property conditions and market comps
- Work with a CPA to project tax changes
- Appeal if the reassessed value seems inaccurate
With the right support, you can challenge an unfair valuation or plan around upcoming increases.
