When you prepay property taxes at closing, you’re actually covering two separate charges bundled into your settlement statement: a proration that settles up with the seller for the current tax period, and an initial deposit that funds the escrow account your lender will use to pay future tax bills. Together they can add several thousand dollars to your cash-to-close, and the total depends almost entirely on where your closing date falls in the local tax cycle.
The Proration Between You and the Seller
Property taxes cover a set assessment period, and closings almost never line up cleanly with the start or end of one. A proration divides the current period’s bill so each party pays only for the days they owned the property. For federal tax purposes, the IRS treats the seller as paying taxes up to but not including the date of sale, and the buyer as paying from the date of sale forward.1Internal Revenue Service. Publication 530 (2025), Tax Information for Homeowners Local proration customs sometimes differ, but the IRS rule governs who can claim the deduction.
How the money moves at the closing table depends on whether the current bill has already been paid. If the seller prepaid the full year, you reimburse them for the months you’ll own the home, and that reimbursement shows up as a charge to you and a credit to the seller on the Closing Disclosure.2Consumer Financial Protection Bureau. 12 CFR 1026.38 – Content of Disclosures for Certain Mortgage Transactions (Closing Disclosure) If the taxes haven’t been paid yet, the seller’s share comes out of their sale proceeds and gets credited to you to cover their portion of the bill when it comes due. Either way, the taxing authority ends up whole.
Why the Lender Makes You Fund an Escrow Account
The bigger piece of your prepayment sets up an escrow account, and the reason is protective rather than punitive. A property tax lien outranks a mortgage lien in priority. If you fell behind on taxes and the county placed a lien on the property, that lien would jump ahead of your lender’s mortgage.3Internal Revenue Service. IRM 5.17.2 Federal Tax Liens – Section: Real Property Tax and Special Assessment Liens In a worst case, the lender’s security interest could be wiped out by a tax sale.
An escrow account removes that risk. Your servicer collects a portion of the annual tax bill each month with your mortgage payment, holds those funds, and pays the taxing authority directly when the bill comes due. You never have to write a separate check for property taxes. The tradeoff is a sizable deposit at closing to get the account started.
How the Initial Escrow Deposit Is Calculated
Two things go into the initial deposit, and understanding both explains why the number can look so large.
The first is gap funding. Your servicer needs enough in the account to cover the first tax bill that comes due after closing. Your monthly escrow contributions will build the balance over time, but if the first installment hits two or three months after closing, those payments alone won’t be enough. The initial deposit fills the gap.
The second is a federally regulated cushion. Regulation X, which implements the Real Estate Settlement Procedures Act, allows your servicer to collect a reserve of no more than one-sixth of the estimated annual escrow disbursements.4Consumer Financial Protection Bureau. 12 CFR 1024.17 – Escrow Accounts One-sixth of a year is two months, so the maximum cushion equals two months’ worth of tax and insurance payments. This buffer protects the servicer against unexpected tax increases or timing gaps.
The calculation works so the projected balance never dips below zero at any point in the year, with the cushion sitting on top of that minimum. The closer your closing falls to a major tax due date, the more gap funding you need because your monthly payments haven’t had time to build. Close right after an installment is paid and the deposit runs higher; close right before one and your monthly payments do more of the work.
A Worked Example
Say you close on March 1. The annual property tax bill is $6,000, payable in two installments of $3,000 each on May 1 and November 1, and taxes for the current period have not been paid.
The daily tax rate is $16.44 ($6,000 divided by 365 days). Under IRS rules, the seller owns January 1 through February 28, which is 59 days. The seller’s share works out to $969.96 (59 × $16.44), pulled from their proceeds and credited to you at closing.
For the escrow deposit, the servicer needs $3,000 available by May 1. Your monthly escrow payment will be $500 ($6,000 ÷ 12). Between closing and the May due date you’ll make two monthly payments totaling $1,000, so the servicer needs $2,000 at closing to fill the gap. Add the two-month RESPA cushion of $1,000 ($500 × 2), and the initial escrow deposit comes to $3,000.4Consumer Financial Protection Bureau. 12 CFR 1024.17 – Escrow Accounts
Your total property-tax-related cash at closing is the $3,000 escrow deposit offset by the $969.96 seller credit. Because these live in different sections of the Closing Disclosure, you have to look at both pages to see the whole picture.
Where the Charges Appear on Your Closing Disclosure
The two components land in different places, which is why many buyers don’t realize they’re paying for two separate things.
The proration between you and the seller appears on Page 3, in the Summaries of Transactions section, itemized under labels like “City/Town Taxes” or “County Taxes.”2Consumer Financial Protection Bureau. 12 CFR 1026.38 – Content of Disclosures for Certain Mortgage Transactions (Closing Disclosure) Depending on whether the seller already paid the current year’s taxes, this line will be a charge or a credit to you.
The initial escrow funding, including the cushion, appears on Page 2 under Section G, labeled “Initial Escrow Payment at Closing.” That section breaks down how many months of taxes and insurance are being collected and the dollar amount for each.2Consumer Financial Protection Bureau. 12 CFR 1026.38 – Content of Disclosures for Certain Mortgage Transactions (Closing Disclosure) If the month count looks high, compare it against the gap between your closing date and the next tax due date, then add two months for the cushion. That arithmetic should account for the total.
Can You Skip the Escrow Requirement?
If tying up thousands of dollars in an escrow account bothers you, a waiver is possible in some cases but not all.
For conventional loans, Fannie Mae requires lenders to maintain a written escrow waiver policy, and that policy cannot rest solely on your loan-to-value ratio. The lender also has to evaluate whether you can actually handle lump-sum tax and insurance payments on your own.5Fannie Mae. Escrow Accounts In practice, most lenders want at least 20% equity and a solid credit history before they’ll consider it. Even then, waivers usually come with a cost, either a one-time fee (often 0.25% to 0.50% of the loan amount) or a small bump to your interest rate.
Government-backed loans are harder. FHA guidelines require lenders to establish and maintain escrow accounts, with waivers available only in narrow circumstances authorized by the mortgagee.6U.S. Department of Housing and Urban Development. FHA Single Family Housing Policy Handbook VA and USDA loans carry similar expectations. For most borrowers with government-backed financing, escrow is effectively mandatory.
If you’re paying cash with no mortgage, no lender is involved and no escrow account is required. You’ll still owe the proration adjustment at closing but skip the large escrow deposit, and you’ll be responsible for paying the taxing authority directly going forward.
Watch for a Supplemental Tax Bill
One cost that catches new homeowners off guard is the supplemental property tax bill. When a property changes hands, many jurisdictions reassess its value. If the new assessment is higher than the prior one, the county issues a supplemental bill covering the difference for the remainder of the tax year. These bills typically are not covered by your escrow account, and your lender may not even receive a copy. You pay them directly. Ask your settlement agent whether your area issues supplemental assessments so the bill doesn’t arrive as a surprise.
