Property taxes are local and can change
A property tax bill is based on local assessment and tax rules. The amount can change because of reassessment, tax rates, exemptions, levies, or local budget decisions. A lender may collect estimated taxes through escrow, but the local authority determines the bill.
Assessment and tax rate
Local assessors generally determine an assessed value under state and local law, and taxing authorities apply applicable rates, levies, or formulas. The assessed value may differ from a buyer's purchase price or a current market estimate. Assessment schedules, appeal rights, exemptions, and billing dates vary by location.
Use the local assessor or tax collector's official records for the property. Ask about pending reassessments, special assessments, tax districts, and exemptions that may not transfer to a new owner.
Property taxes and mortgage escrow
With escrow, the mortgage servicer collects part of the estimated annual tax and insurance cost with the monthly mortgage payment and pays bills when due. The servicer may review the account periodically. If the expected tax or insurance amount changes, the monthly escrow portion can rise or fall, and a shortage or surplus can be handled under the loan and applicable rules.
Read the CFPB explanation of escrow accounts and Mortgage Payments guide for how taxes affect total monthly housing costs.
Review your property tax bill
- Confirm parcel number, owner information, property description, and assessed value.
- Check the applicable exemptions and assessment date.
- Compare the tax rate and local charges with the official bill.
- Check due dates and payment options through the official tax collector.
- Ask the assessor about correction or appeal deadlines if information appears wrong.
Do not assume an exemption available to a seller will apply automatically to a new owner.
Federal tax treatment is a separate question
Whether state and local property taxes are deductible on a federal tax return depends on current federal tax law, itemizing, limits, and the taxpayer's circumstances. This guide does not calculate deductions or provide tax advice. Consult the current IRS publication and a qualified tax professional before relying on a tax benefit.
The IRS updates Publication 530: Tax Information for Homeowners and related instructions as rules change.
Plan for changes in the monthly amount
If taxes are escrowed, the servicer may adjust the escrow amount after a tax bill changes. If you pay taxes directly, set aside funds throughout the year so the bill does not become a surprise. Review the annual escrow statement and contact the servicer if the projected bill looks inaccurate.
Frequently Asked Questions
Does my mortgage lender set the property tax bill?
No. Local taxing authorities and assessment offices set and administer property taxes under applicable law. A servicer may collect and pay them through escrow.
Can the payment increase even with a fixed-rate mortgage?
Yes. The principal-and-interest component may remain fixed, while escrowed property taxes or insurance can change.
Can I appeal an assessment?
Many jurisdictions have an appeal or review process, but deadlines, evidence, and rules are local. Contact the assessor or local board.
Are property taxes automatically deductible?
No. Federal tax treatment depends on current law and the taxpayer’s situation. Consult current IRS guidance.
