What is an impound account?
Impound account, escrow account, reserve account — three names for the same thing. Here is what it actually does, why lenders want one, and what it costs you.
Key takeaways
- An impound account is money your mortgage servicer collects monthly to pay your property taxes and homeowners insurance on your behalf.
- Impound, escrow and reserve account describe the same arrangement — “impound” is the common West Coast term.
- Lenders require them to protect their collateral, because unpaid taxes can become a lien ahead of the mortgage and a lapsed policy leaves the asset uninsured.
- The recurring cost is not the issue; the cost is the reserves collected as cash at closing.
- Escrow payments are estimates, so a mortgage payment can rise in year two even on a fixed-rate loan.
What an impound account is
An impound account is a holding account your mortgage servicer maintains on your behalf. Each month, on top of principal and interest, you pay an extra amount into it. When your property tax bill and homeowners insurance premium come due, the servicer pays them out of that account.
You will see all three names used interchangeably. Impound is the common term on the West Coast, escrow is more common elsewhere, and reserves usually refers specifically to the lump sum collected at closing to seed the account. They describe the same arrangement.
The important structural point: the money is yours, but you do not control it. You cannot see the account balance the way you see a checking account, you cannot choose when disbursements happen, and you cannot use the funds for anything else.
Why lenders require them
An impound account exists to protect the lender’s collateral, not to help you budget.
Unpaid property taxes generally become a lien on the property that can take priority over the mortgage — meaning the taxing authority can be paid before the lender if things go badly. And if a homeowners policy lapses, an uninsured fire can wipe out the asset securing the loan. Both outcomes are catastrophic for a lender, and neither is within their control if the borrower pays the bills directly.
So the lender takes control of the payments. From their side it is straightforward risk management, and it is why impound requirements tend to be strictest on the loans where the lender has the least equity cushion.
How the monthly amount is set
The servicer estimates your annual property tax and insurance obligation, divides by twelve, and adds that to your monthly payment. They also typically hold a cushion — an extra buffer so the account does not run dry if a bill comes in higher than projected.
The weakness in this model is the estimate. At closing on a purchase, the only tax figure on record is usually the previous owner’s, which may reflect an assessed value set years ago. If you paid substantially more than the prior assessed value, your real tax bill will be higher than the number your escrow was built on — sometimes dramatically so.
That gap does not stay hidden. It surfaces later, either as an escrow shortage or, in California, as a supplemental tax bill that arrives separately and often is not escrowed at all.
Shortages, surpluses and the annual analysis
Servicers generally review escrow accounts once a year. If the account collected more than it needed, you may get a refund or a lower monthly payment. If it collected too little, you get a shortage.
A shortage is usually resolved in one of two ways, and often both at once: a lump-sum request to make the account whole, and a higher monthly payment going forward to cover the new, higher estimate. This is why a mortgage payment can jump noticeably in year two even on a fixed-rate loan — the principal and interest did not change, the escrow portion did.
For a buyer who was told their payment would be a certain number, this is an unwelcome surprise. The cause is almost always the same: the account was sized on a stale tax figure.
What it costs you
The recurring monthly collection is not really a cost — you owe the taxes and the premium regardless, and spreading them over twelve months is genuinely easier than facing two large bills a year.
The real cost is at closing. Setting up the account requires seeding it, and those reserves are collected as cash at closing on top of your down payment and other costs. In a high-tax area that can be a substantial line item on your Loan Estimate — capital that is no longer available for the down payment, a rate buy-down, or the work the house needs.
There is also an opportunity cost while the money sits there. Depending on your state and lender, escrow balances may earn little or no interest for you.
The alternative
The service an impound account provides — someone reliably paying your taxes and insurance on time — is genuinely valuable. The reserve requirement attached to it is a separate thing.
Some borrowers qualify to waive the lender impound entirely and handle the bills themselves. That frees the capital but puts the burden back on you, including the discipline to set money aside all year and the risk of a missed deadline. See our guide to escrow waivers for how that works.
Easy Impound sits between the two. We take on the collection, monitoring and payment — the whole job the impound account was doing — without requiring months of reserves at closing. See Reserve Eliminator.
Common questions
Is an impound account the same as an escrow account?
Yes. Impound, escrow and reserve account all describe the same arrangement. “Impound” is more common on the West Coast and “escrow” elsewhere.
Can I cancel my impound account?
Sometimes. Whether you can remove an existing impound depends on your loan program, your equity position and your servicer’s policies, and some loan types require it for the life of the loan. Ask your servicer what applies to your specific loan.
Why did my mortgage payment go up when my rate is fixed?
Almost always the escrow portion. Principal and interest are fixed; property taxes and insurance premiums are not. When the annual escrow analysis finds the account is short, the monthly collection rises to match the new estimate.
Does my escrow balance earn interest?
It depends on your state and your servicer. Some states require servicers to pay interest on escrow balances and many do not. Check your state’s rules and your servicing agreement.
