Property tax escrow accounts, explained

Last reviewed Sources & methodology

Why your mortgage servicer collects extra each month, what the federal rules actually require, and how to read the once-a-year statement that decides whether your payment goes up.

If you have a mortgage, you probably don't pay your property tax directly. Your servicer collects roughly one-twelfth of the annual bill with each payment, holds it in an escrow account (called an "impound account" in much of the Western US), and pays the county and your insurer when the bills come due. To estimate the monthly amount, use the escrow calculator. This guide explains the rules behind that number and the events that change it.

Who escrow is really for

Escrow exists primarily to protect the lender. Unpaid property taxes become a super-priority lien that can sit ahead of the mortgage, and a lapsed insurance policy leaves the collateral exposed. Collecting both in advance guarantees they get paid. It happens to help most homeowners too, by turning two intimidating lump sums into a level monthly amount — but the account is structured around the lender's risk, not your convenience.

The federal rules: RESPA and the 2-month cushion

Escrow accounts are governed by the federal Real Estate Settlement Procedures Act, specifically Regulation X, 12 CFR § 1024.17. The rules that matter most to you:

  • The cushion is capped. A servicer may keep at most a two-month reserve of escrow disbursements — no more. This buffer absorbs the gap when tax or insurance rises before your monthly amount catches up.
  • An annual analysis is required. Once a year the servicer must reconcile what it projected against what it actually paid, and recompute your monthly amount.
  • Overages get refunded. If the analysis finds a surplus of $50 or more above the allowed cushion, the servicer must return it to you (typically within 30 days).
  • Their mistakes are their problem. If the servicer misses a payment it was holding your money to make, RESPA requires it to cover any resulting penalties — not you.

Why your payment went up (the usual culprit)

On a fixed-rate loan, the principal-and-interest portion of your payment never changes. So when the total jumps, escrow is almost always the reason. The annual analysis recalculates your monthly amount whenever the underlying bills move — and a single increase can hit you twice:

  • The going-forward amount rises. A higher tax or insurance bill means a higher one-twelfth.
  • A shortage is spread on top. If the account didn't hold enough to cover the higher bill, the servicer recovers the gap over the next 12 months, stacked onto the new monthly amount.

That combination is why a property-tax increase of, say, $1,500 can feel like a payment jump of more than $200 a month — the new run-rate plus the catch-up. The catch-up disappears after a year; the higher run-rate stays.

How to read your annual escrow statement

Once a year you'll receive an Annual Escrow Account Disclosure Statement. It is worth five minutes of your attention. Look for:

  • Projected vs. actual disbursements — what they expected to pay for tax and insurance vs. what they actually paid.
  • Shortage or surplus — and how a shortage is being spread, or a surplus refunded.
  • The new monthly payment — and the effective date.
  • The lowest projected balance — this is where the cushion is tested.

If the projected tax figure looks wrong — for instance, it missed an exemption you now qualify for, or it's still using a pre-reassessment value — call before the next disbursement. Servicer data feeds lag the county, and errors are most common on non-homestead properties, multi-parcel lots, and recently reassessed homes.

Can you waive escrow?

Often, yes — if your loan-to-value is 80% or below and your loan program allows it. Waiving lets you hold your own tax and insurance money and earn interest on it until the bills come due. The trade-offs: some lenders charge a small fee or a slightly higher rate for a non-escrowed loan, FHA and VA loans generally require escrow regardless of equity, and you take on the discipline of budgeting for large bills yourself.

A note on interest: in most states the servicer keeps the float on your escrow balance. A minority of states require interest to be paid on escrow — but the rate is usually nominal, so it's rarely the deciding factor.

What happens to the balance when you leave

The escrow balance is your money held in trust, not a fee. When you pay off or refinance the loan, the remaining balance — cushion included — is refunded to you, typically within about 20 days of payoff. A refinance simply starts a fresh escrow account with the new lender, funded again at closing.
