Real estate taxes on a mortgage are the property taxes your lender collects as part of your monthly payment, holds in an escrow account, and pays to your local government on your behalf when the bill comes due. Most homeowners never write a check directly to the county tax office. The servicer handles it, which protects the lender’s collateral and spreads the annual bill across twelve payments instead of one.
How Escrow Collects and Pays Your Taxes
A standard mortgage payment has four parts, often called PITI: principal, interest, taxes, and insurance. Principal reduces the loan balance. Interest is the lender’s return. Taxes and insurance are collected on top of the loan itself so the property stays insured and free of government liens.
The tax portion works like forced savings. Your servicer estimates the annual property tax bill, divides it by twelve, and adds that amount to each monthly payment. The money sits in a dedicated escrow account, separate from the servicer’s operating funds, until the tax bill is due. Then the servicer pays the taxing authority directly out of the account.
Federal law caps what the servicer can collect. Section 10 of the Real Estate Settlement Procedures Act, at 12 U.S.C. § 2609, limits the monthly charge to one-twelfth of the estimated annual total.1Office of the Law Revision Counsel. 12 USC 2609 – Limitation on Requirement of Advance Deposits in Escrow Accounts On top of that, the servicer may hold a cushion of no more than one-sixth of the estimated annual total, roughly two months of payments, as a buffer against tax increases.2Consumer Financial Protection Bureau. 12 CFR 1024.17 – Escrow Accounts The servicer cannot pad the account beyond that.
One thing the account usually does not do is earn you interest. No federal rule requires servicers to pay interest on escrow balances. A handful of states require it, but federal savings associations are generally exempt under federal preemption. If your loan contract is silent, expect nothing on the thousands of dollars that may sit there for months.
Why Your Payment Changes Even on a Fixed-Rate Loan
Tax rates and assessed values move constantly, so what the servicer collected last year rarely matches what it actually paid out. At the end of each computation year, the servicer must run an escrow account analysis, recalculate your monthly deposit for the coming year, and send you an annual escrow statement within 30 days of finishing the analysis.2Consumer Financial Protection Bureau. 12 CFR 1024.17 – Escrow Accounts
That analysis is the main reason a “fixed-rate” mortgage payment isn’t actually fixed. Principal and interest hold steady. Taxes and insurance drift with the real world. In fast-appreciating markets, an escrow adjustment can add a hundred dollars or more to the monthly payment in a single year.
Surpluses
If the servicer collected more than it needed, you have a surplus. When the surplus is $50 or more, the servicer must refund it to you within 30 days.2Consumer Financial Protection Bureau. 12 CFR 1024.17 – Escrow Accounts Anything under $50 can be refunded or credited toward next year’s payments.
Shortages
A shortage means the account came up short of the bills the servicer paid. If the shortage is less than one month’s escrow payment, the servicer can require you to repay within 30 days or spread it over at least 12 months. If the shortage equals or exceeds one month’s payment, the servicer cannot demand a lump sum and must offer at least 12 months to repay.2Consumer Financial Protection Bureau. 12 CFR 1024.17 – Escrow Accounts Your monthly escrow amount will typically rise as well, so the same gap doesn’t open next year.
When You Can Skip Escrow and Pay Taxes Yourself
Whether you can avoid escrow depends on your loan type, your equity, and your payment record.
FHA loans require escrow for the entire life of the loan. There’s no waiver, regardless of down payment or payment history. VA and USDA loans carry similar requirements in practice. For higher-priced conventional mortgages, where the rate exceeds a set threshold above the average prime offer rate, federal rules require escrow until the unpaid balance falls below 80 percent of the original property value.3Federal Register. Escrow Requirements Under the Truth in Lending Act Regulation Z Most lenders also require escrow on any conventional loan when the down payment is under 20 percent.
Once you have enough equity, you can ask your servicer for an escrow waiver. Fannie Mae’s servicing guidelines require the servicer to deny the request if your loan balance is 80 percent or more of the original appraised value, if you’ve had any late payment in the past 12 months, if you’ve been 60 or more days late in the past 24 months, or if you’ve had a prior loan modification.4Fannie Mae. Administering an Escrow Account and Paying Expenses Meet those conditions and the servicer has discretion to approve the waiver, though it isn’t required to offer one on its own.
Waiving escrow makes you personally responsible for paying property taxes and insurance on time. Forget, and a tax lien lands on your home. Many people who qualify for a waiver keep the account anyway because the autopilot outweighs the value of holding the cash themselves.
How Your Tax Bill Gets Calculated
Two numbers set your annual property tax: the assessed value of your home and the tax rate, often expressed as a millage rate.
A county or municipal assessor estimates market value and applies an assessment ratio to produce a taxable assessed value. That ratio varies by jurisdiction: some assess at full market value, others at a fraction. Assessments typically update every one to two years, and you receive a notice showing the new figure.
Local taxing bodies then set rates in mills. One mill equals one dollar of tax for every thousand dollars of assessed value. On a home with a $200,000 assessed value and a combined 25-mill rate, the annual tax is $5,000. Different authorities stack their rates: a county might levy 10 mills, the school district 12 mills, a fire district 3 mills, all adding up to the total.
If the assessed value looks too high, you can appeal. Most jurisdictions give you a window after the assessment notice arrives to challenge the valuation before a local review board. The usual argument is that the assessment exceeds what the home would actually sell for, or that comparable properties nearby were assessed for less. A successful appeal lowers your tax bill, which eventually flows through as a lower escrow payment.
Exemptions That Lower What Escrow Has to Collect
Many local governments offer exemptions that reduce your taxable assessed value, cutting the bill your escrow account has to cover. Common categories include:
- Homestead exemptions, which reduce the taxable value of a primary residence by a set dollar amount and exist in a majority of states.
- Senior exemptions, often kicking in at age 65 and sometimes tied to income limits.
- Veteran and disability exemptions, ranging from modest reductions for partial service-connected disability to complete exemptions for total and permanent disability.
- Widow and widower exemptions, offered in some areas to surviving spouses.
These don’t apply automatically. You have to file with your county assessor or tax office and provide documentation. If you qualify and never applied, you’ve been overpaying, and your escrow has been higher than it needed to be. It’s worth checking with the local assessor after any life event that might qualify you: buying a first home, turning 65, or receiving a disability rating.
Deducting the Taxes You Paid Through Escrow
Property taxes paid through escrow are deductible on your federal return, but only if you itemize instead of taking the standard deduction.5Internal Revenue Service. Potential Tax Benefits for Homeowners The deduction sits under 26 U.S.C. § 164, which allows a deduction for state and local real property taxes.6Office of the Law Revision Counsel. 26 USC 164 – Taxes
Property taxes are bundled into the broader state and local tax deduction, commonly called SALT, which also covers state income or sales taxes. For the 2026 tax year, the SALT deduction is capped at $40,400 for most filers, or $20,200 for married filing separately. Those caps were raised from the prior $10,000 limit by the One Big Beautiful Bill Act and are scheduled to increase by one percent each year through 2029. A phase-out reduces the cap for filers with modified adjusted gross income above $505,000 ($252,500 for married filing separately).
Timing matters. You deduct property taxes in the year the servicer actually paid them to the local government, not the year the money was collected from you. Your annual escrow statement and IRS Form 1098 show the disbursed amount, which is the figure to use on your return.
What Happens If the Taxes Don’t Get Paid
An unpaid property tax bill creates a lien on the property itself, not on you personally. That lien holds a priority position in most states: it jumps ahead of nearly every other claim against the home, including your mortgage. In a forced sale, the local government gets paid before your lender. That priority is exactly why lenders insist on escrow in the first place.
If you handle taxes yourself and fall behind, the penalties compound quickly. Local governments charge interest on delinquent balances at rates that can reach double digits. After a period of delinquency, the taxing authority can initiate a tax sale, transferring either the lien or the property to satisfy the debt. Your lender, watching its collateral erode, can pay the taxes on your behalf and add the amount to your loan balance or demand immediate repayment. In serious cases, the lender can declare you in default and start foreclosure.
Even with an escrow account, verify the taxes are actually being paid. Servicer errors happen, and the lien attaches to your property regardless of whose mistake it was. Your annual escrow statement and your local tax office’s online records are the two places to confirm everything is current.
