Under federal rules in Regulation X, each of these has defined limits and deadlines, and your annual escrow statement shows which one applies to your loan.
What a mortgage escrow account does
A mortgage escrow account, also called an impound account, is run by your mortgage servicer to collect and pay certain property charges, most often property taxes and homeowners insurance premiums. You pay a portion of those costs with each monthly mortgage payment, and the servicer pays the bills when they come due. The servicer still calculates the amounts and makes the payments, so the account spreads large annual bills across twelve months rather than changing who is responsible for them. The Consumer Financial Protection Bureau explains the arrangement in its guidance on what an escrow or impound account is.
The detailed federal rules discussed below come from Regulation X, which applies to covered federally related mortgage loans. Your loan documents and state law can add requirements, and not every mortgage follows identical escrow terms. The regulation text is available at 12 CFR § 1024.17 (escrow accounts) and 12 CFR § 1024.34 (timely escrow payments and treatment of balances).
Why did my mortgage payment go up?
An escrow-driven payment increase typically has one of these causes:

#1 Best Overall
- A property tax bill or assessment is higher than the amount the servicer projected last year.
- An insurance premium has increased at renewal, or the coverage amount changed.
- The prior year ended with a shortage, so the servicer is spreading the catch-up across future payments.
- The servicer has adjusted the permitted cushion (the extra reserve held in the account) based on the new projections.
To confirm which cause applies to you, work through the statement in this order:
- Open the annual escrow statement from your servicer. You can usually find it in the escrow or documents section of the servicer’s online account, or request a copy by phone or in writing.
- Find the projected disbursements for the coming year. Compare each tax and insurance figure against your latest tax bill or insurance renewal notice.
- Find the line showing the prior year’s account history, including the ending balance and any shortage, surplus, or deficiency.
- If a number does not match a document you hold, ask the servicer in writing to explain how it was calculated and to send the bills it used.
What the annual escrow statement must contain
Regulation X requires an escrow analysis before an account is established and again at the end of each escrow computation year. The servicer generally must send the annual statement within 30 days after that computation year ends. It should show an account history for the prior year and a projection for the next year, including the mortgage payments made and their escrow portions, the amounts deposited and paid out, the ending balance, and how any surplus, shortage, or deficiency is being handled. The statement is the document to check first, because it is the servicer’s own record of what was paid and what it expects to pay.
How much can be collected each month
For covered loans, the general federal limit allows monthly escrow collections of one-twelfth of reasonably anticipated annual escrow payments. The account may also keep a cushion, but the cushion may be no greater than one-sixth of estimated annual disbursements, which is roughly two months of bills. This is a general limit under Regulation X, not a payment quote for your loan. The initial deposit at closing and other loan-specific terms can differ. For a plain-language overview of the cap, see the CFPB answer to whether there is a limit on how much a mortgage lender can make you pay into escrow.
Surplus, shortage, or deficiency: which one is it?
These three terms describe different positions and are not interchangeable. A surplus is an account balance above the target balance. A shortage is a balance below the target balance. A deficiency is a negative account balance. Each has different repayment or refund treatment, and the treatment also depends on whether you are current on the mortgage and how large the amount is compared with one month’s escrow payment.

|---|---|---|
| Surplus | Balance above the target balance | If you are current and the surplus is $50 or more, it must be refunded within 30 days of the analysis. If it is below $50, the servicer may refund it or credit it toward next year’s escrow payments. If you are not current, the servicer may retain the surplus as the loan documents allow. |
| Shortage | Balance below the target balance | Below one month’s escrow payment: the servicer may leave the shortage, require repayment within 30 days, or spread repayment over at least 12 months. At or above one month’s escrow payment: the servicer may leave the shortage or spread repayment over at least 12 months. |
| Deficiency | Negative account balance | For a current borrower, below one month’s escrow payment: the servicer may leave it, require repayment within 30 days, or require repayment in two or more equal monthly payments. At or above one month’s escrow payment: the servicer may leave it or require repayment in two or more equal monthly payments. |
Why a shortage is not the same as a deficiency
People often use these words loosely, but the statement uses them precisely. A shortage means the account is short of its target but may still hold money. A deficiency means the account has been overdrawn to a negative balance because disbursements were paid before enough funds were collected. The repayment options differ, so confirm which term your statement uses before you respond to it.
When is an escrow surplus refunded?
The $50 threshold is the key dividing line for a current borrower. Consider two illustrative cases, not tied to any particular loan. A $38 surplus for a current borrower may be refunded or credited to next year’s escrow payments, at the servicer’s choice. A $212 surplus must be refunded within 30 days of the analysis. If you are not current, the servicer’s ability to retain a surplus depends on what the loan documents provide, so the refund rule above does not promise a payout in that situation.

For a loan with required escrow payments, the servicer must make each disbursement on or before its due date to avoid a penalty, under 12 CFR § 1024.34(a). If a bill was paid late or never paid, the consequences depend on the loan, the taxing authority or insurer, state law, and the facts. Possible outcomes include penalties, a tax lien, or a lapse or problem with insurance coverage. Work through these steps:
- Contact the servicer in writing and ask for the date each payment was sent and proof of payment, such as a check copy or confirmation number.
- Check the bill directly with the county or local tax office, and ask whether a penalty has been assessed or a lien recorded.
- If the issue involves insurance, confirm the policy is active and the premium is paid by calling or writing to the insurer, not relying only on the servicer’s statement.
- If the servicer cannot resolve a discrepancy, ask it to explain the escrow history in writing and to correct any error it finds.
Verify every account-specific figure with your servicer, and handle unpaid taxes or insurance premiums with the relevant tax authority or insurer. This article explains the general rules and is not legal advice on a particular case.
What happens to escrow money after the mortgage is paid off?
When a mortgage is paid in full, the servicer generally must return any remaining escrow funds under its control within 20 days. That period excludes Saturdays, Sundays, and legal public holidays, so it is not 20 calendar days. Regulation X also contains an exception: the remaining balance may be credited to a new mortgage escrow account if the borrower agrees and the conditions in 12 CFR § 1024.34(b) are met. If you are refinancing or moving the balance, ask the servicer to confirm in writing which option is being used and when the refund or credit will post.
Checklist before you contact your servicer
- Your annual escrow statement and the page showing the prior-year history.
- Your most recent property tax bill and insurance renewal notice.
- The projected disbursement amounts and their due dates.
- The balance category on the statement: surplus, shortage, or deficiency.
- Whether your account is current, since it affects surplus and deficiency treatment.
- A written question list that asks for the calculation, the bill source, and the payment dates.
Federal rules can be amended, and the CFPB’s explanatory pages carry their own update dates. Check the current text of 12 CFR § 1024.17 and 12 CFR § 1024.34 before relying on any figure in this article. The CFPB’s mortgage servicing FAQs on escrow accounts provide additional context, with individual update dates shown on that page.
