Why Your Bill Can Change explained in clear, homeowner-friendly language, plus the exact next steps to take.
Why Your Bill Can Change 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.
Your property tax can go up or down year-to-year due to several factors. Any change in the local budget or assessed values affects the rate. For example, if the city approves a higher budget or new bonds, the mill rate may increase even if your home’s value is unchanged. Similarly, changes in total assessed values (if many homes rise in value) can shift the rate. New York State advises: “Changes to your budget, or the total assessed value, and changes in your own assessment or exemptions” can change your bill. Home assessments themselves change too. If your neighborhood’s home prices have risen, your assessed value may be increased accordingly, which raises your taxes. In fact, one analysis notes “rising home prices
since 2020 have pushed assessments—and in turn, property tax bills—markedly higher in many areas”. Conversely, if your area has caps (like California’s 2% Prop 13 limit), your taxes may grow more slowly. Managing Your Tax Liability Calculating your tax is straightforward when you know the inputs. Many mortgage companies offer online tools to estimate property taxes by ZIP code or home price. ProptaxHelper also provides a Tax Estimator where you can enter your address or values. If your calculated tax seems way off from your bill, check:
Assessed Value: Look up your official assessed value (often on your county assessor’s website). Tax Rate: Confirm the current rate from your local tax authority (often in budget documents).
- Exemptions: Make sure you applied any available exemptions (see our Exemptions article below).
If your tax bill still seems unusually high, consider appealing the assessment. Ready to Save? If you think your assessment is too high or want to find any missed exemptions, visit ProptaxHelper.com. Our tools guide you through calculating your tax and starting an appeal if needed.
