What Is Escrow in a Mortgage? How It Works for Taxes & Insurance
«Escrow» appears at two different points in the homebuying process, and they’re not the same thing. The first is a purchase escrow — the neutral third-party account that holds your earnest money deposit during the transaction. The second is a mortgage escrow account — the ongoing account your lender uses to collect property taxes and insurance. This article covers the second type: the one that affects your monthly payment for the life of your loan.
What a Mortgage Escrow Account Is
When your lender sets up a mortgage escrow account (sometimes called an impound account), they collect a portion of your annual property taxes and homeowners insurance premiums every month as part of your regular payment. They hold these funds in a dedicated account and pay the bills directly to your local tax authority and insurance company when they come due.
Your monthly payment with escrow looks like this:
Total PITI = Principal + Interest + Taxes (escrow) + Insurance (escrow)
Without escrow, you’d pay only principal and interest to your lender each month, and manage taxes and insurance yourself — remembering to set aside money and pay those large bills twice a year (for taxes) and annually (for insurance).
Escrow removes that responsibility. It also removes the risk that you’ll spend the money meant for taxes and face a delinquent property tax bill — which is one reason lenders require it.
Is Escrow Required?
Usually, yes — especially for first-time buyers and anyone putting down less than 20%.
Most conventional lenders require escrow when the loan-to-value ratio exceeds 80%. FHA and VA loans always require escrow. USDA loans require escrow.
Some lenders allow buyers with 20%+ down and strong credit to waive escrow — but they often charge a fee for this option (typically 0.25% of the loan amount, added to your rate or paid upfront). Unless you have a compelling reason to manage taxes and insurance yourself, keeping escrow is the simpler choice for most borrowers.
How Your Escrow Amount Is Calculated
At closing, your lender estimates your annual property tax and insurance costs, divides by 12, and adds that monthly amount to your payment.
Example: $400,000 home in Texas (1.8% property tax rate), 10% down.
| Item | Annual Cost | Monthly Escrow |
|---|---|---|
| Property taxes | $7,200 | $600 |
| Homeowners insurance | $1,800 | $150 |
| Total escrow | $9,000 | $750 |
This $750/month is collected alongside your principal and interest payment. Your full PITI on this example: $2,338 (P&I on $360,000 at 6.75%) + $750 = $3,088/month.
Lenders are also allowed — and required by federal law — to maintain an escrow cushion of up to 2 months’ worth of escrow payments. This ensures the account has funds available even if a tax bill arrives slightly earlier than anticipated. At closing, you’ll typically prepay 2–3 months of escrow into the account to establish this cushion.
The Annual Escrow Analysis
Once a year, your loan servicer reviews your escrow account — this is called the escrow analysis or escrow review. They compare:
- What was collected vs. what was actually paid out
- What your property taxes and insurance will likely cost in the coming year
- Whether your account has a surplus or shortage
If there’s a surplus: Your servicer sends you a refund check (for amounts over $50) or credits your account toward future payments.
If there’s a shortage: This is where homeowners are sometimes caught off guard.
Escrow Shortages: Why They Happen and What to Do
An escrow shortage means your account didn’t have enough to cover your taxes and/or insurance. This happens when:
- Property taxes increased (reassessment, mill rate change, or first-year adjustment after purchase)
- Homeowners insurance premium went up (very common in recent years due to inflation and climate-related risk repricing)
- The initial estimate was too low at closing
When a shortage occurs, your servicer typically gives you two options:
- Pay the shortage immediately — a one-time catch-up payment to bring the account current
- Spread it over 12 months — the shortage is divided by 12 and added to your monthly payment for the next year
Most homeowners choose option 2, which means their monthly payment increases — sometimes by $50–$200/month, seemingly out of nowhere. This surprises buyers who assumed their payment was fixed.
Important: Your principal and interest payment is genuinely fixed (on a fixed-rate loan). The escrow portion is not. Expect your PITI to adjust slightly each year, typically upward, as taxes and insurance costs rise.
What Escrow Pays — and What It Doesn’t
Escrow pays:
- Property taxes (county, city, school district, and any special assessment taxes)
- Homeowners insurance premiums
- Flood insurance premiums (if required by lender)
- PMI premiums (in some cases — many servicers collect PMI through a separate mechanism)
Escrow does not pay:
- HOA dues (you pay these directly to your HOA)
- Utility bills
- Home warranty premiums
- Supplemental tax bills (in some states, a supplemental assessment is sent after purchase that may not be captured in your initial escrow setup — watch for this in California and a few other states)
First-Year Property Tax Caveat
This trips up many first-time buyers. At closing, your lender estimates escrow based on the previous owner’s tax bill. But your purchase may trigger a property tax reassessment — especially in states where property taxes reset to the purchase price (like California under Proposition 13 rules, or many states that assess at market value).
If you buy a home for significantly more than the previous owner’s assessed value, your first tax bill after reassessment could be substantially higher than expected. This means your escrow analysis will show a shortage — possibly a significant one — in the first year.
Ask your real estate agent or lender what the likely reassessed tax bill will be. This is especially important in competitive markets where homes sell well above their prior assessed value.
How to Check Your Escrow Account
Your loan servicer is required to send you an annual escrow statement detailing what was collected and paid. You can also:
- Log in to your servicer’s online portal to see the current escrow balance
- Call your servicer to request an escrow projection for the coming year
- Compare your property tax bills (sent directly from your county) to confirm your servicer paid them correctly and on time
Errors are rare but not unheard of. Confirm your property taxes are marked «paid» in your county’s records once a year. An unpaid property tax bill — even due to a servicer error — can lead to a tax lien on your property.
Can You Change Your Escrow Setup?
Waiving escrow: If your LTV is below 80% and your lender allows it, you can request to remove escrow. You’ll then be responsible for paying taxes and insurance directly. This requires discipline — property tax bills can be $3,000–$8,000+ and arrive twice a year.
Changing insurance providers: Yes, you can switch homeowners insurance at any time. Notify your new insurer and your loan servicer, who will update the payee on the escrow account. Make sure there’s no coverage gap during the transition.
Updating escrow after tax reassessment: If you receive a supplemental tax bill, contact your servicer. They may not be aware of it and it may not be in your escrow schedule.
Frequently Asked Questions
Does my escrow account earn interest? In most states, no — lenders are not required to pay interest on escrow balances. A handful of states (including California, New York, and Connecticut) require lenders to pay interest on escrow accounts. The rates are typically minimal.
What happens to my escrow if I refinance? When you refinance, your old loan is paid off and your old escrow account is closed. The remaining balance is refunded to you within 20 business days. Your new loan sets up a new escrow account, which you’ll fund at closing. Plan for the timing gap — you may need to cover a tax or insurance bill before the new escrow account is fully established.
Can my lender miscalculate my escrow? Yes, though it’s uncommon. If you believe your escrow is being over- or under-collected, request an escrow analysis and review it line by line. The Real Estate Settlement Procedures Act (RESPA) governs escrow accounts and limits how much cushion lenders can require. If you find an error, submit a written complaint to your servicer — they’re required to respond within 30 business days.
What if I can’t pay an escrow shortage? Contact your servicer immediately. Most will work with you on a payment plan. Ignoring a shortage notice means your payment will simply be recalculated upward — the servicer advances the funds and recovers them over time. Avoiding communication makes it worse.
The Bottom Line
Escrow is a convenience that most homeowners appreciate once they understand it — it automates the payment of large, irregular bills and prevents the nightmare of a delinquent property tax situation. The tradeoff is that your monthly PITI payment isn’t as fixed as the «mortgage payment» figure suggests.
Expect your escrow portion to adjust each year. Build a small buffer into your housing budget for annual increases. And check your annual escrow statement when it arrives — it’s one of the few documents in the mortgage servicing world that’s actually worth reading.
