Your Mortgage Payment Just Changed.
Escrow is almost certainly why.
Here's how it works and what you can do.

You opened a letter from your mortgage servicer, or logged into your account, and your monthly payment is different — sometimes by $50, sometimes by $300. Nobody warned you. No interest rate changed. The principal balance is the same. The culprit, almost every time, is the escrow account attached to your loan, and it went up because property taxes, homeowner's insurance, or both went up.

This article explains exactly what an escrow account is, how the annual review process (called an escrow analysis) works, why servicers are allowed to hold a cushion beyond your actual costs, and — critically — what your real options are if the new payment strains your budget. There are more levers here than most homeowners realize.

What an Escrow Account Actually Is (and Isn't)

An escrow account in the mortgage context is a segregated holding account that your mortgage servicer manages. Every month, a slice of your payment goes into it. When your property tax bill comes due — twice a year in most U.S. jurisdictions, though some bill annually or quarterly — the servicer pays it directly from that account. Same with your homeowner's insurance premium. You never write those checks yourself; the servicer does it for you, using money you've been steadily depositing.

This arrangement serves two parties. It serves you by spreading large annual bills into twelve smaller monthly increments. It serves the lender by ensuring that property taxes get paid (a delinquent tax bill can result in a tax lien that takes priority over the mortgage) and that insurance stays current (if your house burns down uninsured, the lender's collateral is gone). The lender's interest is the primary reason escrow accounts are typically mandatory on conventional loans with less than 20% down, and on virtually all FHA, VA, and USDA loans regardless of down payment.

What escrow is not: it is not a savings account you earn interest on (in most states — a handful, including California, Connecticut, and Iowa, do require servicers to pay interest on escrow balances). It is not connected to your interest rate. It is not a penalty. And a change in your escrow payment has zero effect on how quickly you're building equity or paying down principal.

The Escrow Analysis: The Annual Review That Sets Your New Payment

Once a year, your servicer runs what's called an escrow analysis. Federal law — specifically the Real Estate Settlement Procedures Act, known as RESPA, and its implementing regulation Regulation X — requires servicers to perform this analysis and send you a statement showing the results. The statement must arrive at least 30 days before any new payment amount takes effect.

Here's the mechanics of how it works. The servicer looks at what it actually paid out of your escrow account over the past 12 months, then projects what it expects to pay over the next 12 months. If your county property tax assessment went up 8% — something that happened to a lot of homeowners in high-growth markets like Phoenix, Austin, and Boise in the early 2020s — the servicer needs to collect more money going forward. It divides the new projected annual total by 12 and recalculates your monthly escrow contribution.

The analysis also checks your current balance against what RESPA says you're allowed to hold. The law permits servicers to maintain a cushion of up to two months' worth of projected escrow disbursements. If your balance at its lowest point during the year dips below that cushion, the servicer will increase your payment to rebuild it.

This cushion rule catches many homeowners off guard. Your taxes might not have changed at all, but if a large insurance payment hit at an awkward time and temporarily drew your balance below the required minimum, your payment will still go up — not because anything got more expensive, but because the timing created a technical shortfall in the cushion calculation.

Why Your Specific Payment Changed: The Four Most Common Causes

The escrow analysis statement your servicer sends will show the math, but the statement is often formatted in a way that requires a translator. Here are the four actual reasons payments change, ranked by how commonly they show up.

1. Property tax reassessment. This is the most common cause in most markets. County assessors periodically reassess home values, and in a rising market those assessments follow. In Texas, for example, assessed values are reassessed annually and have risen sharply in many counties since 2020. A home that was assessed at $350,000 and is now assessed at $430,000 generates a significantly larger tax bill, and your servicer will increase escrow accordingly.
2. Homeowner's insurance premium increase. The U.S. homeowner's insurance market has been under significant pressure since roughly 2021, driven by increased catastrophic weather events, reinsurance cost increases, and in some states — Florida and Louisiana especially — insurer exits from the market. Many homeowners saw insurance premiums jump 20–40% at renewal in 2022 and 2023. Your servicer sees the new premium when it pays your renewal bill, and your next escrow analysis will reflect it.
3. Escrow shortage from prior year. If your servicer underestimated costs last year and paid out more than it collected, there's a shortfall. RESPA allows servicers to spread repayment of a shortage over 12 months rather than demanding a lump sum, but that spread repayment adds to your new monthly payment. Importantly, if the shortage is less than one month's escrow payment, the servicer must give you the option to pay it off in a lump sum instead.
4. Loss of tax exemption. Property tax exemptions — homestead exemptions, senior citizen exemptions, veteran exemptions — reduce your tax bill and therefore your escrow requirement. If an exemption expires, wasn't re-filed, or if the property changed hands and the exemption wasn't reapplied for, your effective tax bill can jump by hundreds of dollars annually. This one often comes as a genuine surprise because homeowners forget to re-file.

A fifth cause worth mentioning: an initial escrow estimate that was simply wrong. At closing, your lender estimated your escrow needs based on available data. If the first tax bill that hit after closing was larger than projected — which happens when you buy mid-year and the full-year assessment comes due — the shortfall shows up in year one's analysis and the correction can feel dramatic.

How to Read the Escrow Analysis Statement Your Servicer Sends

Servicers are required to send you a statement, but many use formats that are genuinely difficult to parse. Most statements share a common structure once you know what to look for.

The statement will typically show a month-by-month table called an escrow account projection or escrow account history. Each row represents one month. Columns show the expected payment into escrow, the expected disbursement out of escrow, and the running balance at the end of that month. At the bottom, it identifies the lowest projected balance for the coming year, compares that to the required cushion, and calculates whether there's a shortage or surplus.

The critical line is the one that compares your projected low point to the required minimum balance (the two-month cushion). If the projected low point is below the required minimum, the difference is your shortage. If it's above, you have a surplus — and RESPA requires the servicer to return surpluses over $50 to you, either as a check or a credit to your next payment.

When you get this statement, do these specific checks:

• Find the line showing what your servicer expects to pay for property taxes. Compare it to your most recent actual tax bill. If the numbers differ significantly, call your county assessor's office to confirm what's actually owed — servicers occasionally use outdated figures.
• Find the insurance premium line and compare it to your actual insurance renewal declaration page. If you recently switched insurers or negotiated a lower premium, your servicer may not have the updated figure yet.
• Look at the disbursement dates in the projection table. Are they realistic? Taxes in your county might be due in April and October, and if the projection has them in different months, the low-point calculation will be off.

If you find an error, call your servicer with documentation — your tax bill and your insurance dec page are the two documents you need. Servicers can and do correct escrow analyses when given accurate information.

What You Can Actually Do If the New Payment Is a Problem

You have more options than the servicer's letter implies. Here's what's genuinely available to you, in order of effort required.

1. Pay the shortage lump sum. If your statement shows a shortage — meaning your account was underfunded over the past year — you can pay it in full rather than spreading it over 12 months. This brings your base monthly payment back down to the new projected amount without the shortage surcharge on top. Call your servicer to get the exact shortage figure and the process for submitting a one-time payment to the escrow account. This makes sense if the shortage is modest and you have the cash, because the monthly reduction is immediate.

2. Appeal your property tax assessment. If rising property taxes are driving the escrow increase, you can challenge the assessment directly with your county. The process varies by jurisdiction, but most counties have a formal appeal period each year — often 30 to 90 days after assessment notices are mailed. In many markets, a meaningful percentage of appeals succeed, particularly if comparable sales data supports a lower value. If you win an appeal, your tax bill drops, and at your next escrow analysis, your payment will come back down. Some homeowners hire property tax consultants who work on contingency; firms like Ownwell and Protest My Tax operate in several states and charge a percentage of the savings, not an upfront fee.

3. Shop your homeowner's insurance. If a premium increase is the driver, get competing quotes before your next renewal. Switching insurers mid-policy is allowed; you'll typically receive a prorated refund from your current insurer. Provide your servicer with the new declaration page showing the lower premium, and it can update the escrow projection. Be careful here: don't drop coverage levels just to cut cost. Make sure you're comparing policies with equivalent dwelling coverage, not just headline premiums.

4. Request an escrow waiver. If you've now crossed the 20% equity threshold in your home and your loan is a conventional (non-government) loan, you may be eligible to cancel the escrow requirement entirely and pay taxes and insurance yourself. You'll likely need to pay a small waiver fee — commonly 0.125% to 0.25% of the loan balance — and you'll need a good payment history. This puts you in charge of those large annual payments, which requires discipline but eliminates the servicer's cushion requirement and gives you use of that money until the bills are due.

5. Refinance — but be realistic about the math. If your rate is significantly above current market rates and you were planning to refinance anyway, a refi will involve a new escrow setup. But refinancing specifically to solve an escrow problem almost never makes financial sense given closing costs. Only consider this if the refi was already justified on rate grounds.

The Property Tax Appeal Process: A Closer Look at the Lever Most Homeowners Ignore

Property tax appeals are underused. Research published by the Lincoln Institute of Land Policy has found that in many jurisdictions, assessed values systematically over-represent lower-value properties relative to higher-value ones — meaning any given homeowner has a reasonable shot at a reduction if they actually file. Yet the vast majority of homeowners never appeal, either because they don't know they can or because the process sounds daunting.

It isn't, particularly, once you know the structure. The typical appeal process works like this:

1. Get your assessment notice. This usually arrives in spring. It shows your assessed value and the appeal deadline, which is almost always a hard cutoff — missing it by one day means waiting a full year.
2. Pull comparable sales. Your argument is that your assessed value is higher than what the property would actually sell for. You need recent sales — typically within the past 6 to 12 months — of similar properties in your immediate area. County assessor websites often provide these for free. Zillow and Redfin can supplement, but actual recorded sale prices are what you want.
3. File the appeal. Most counties have an online portal or a paper form. The form asks for your parcel number, your estimate of market value, and your supporting evidence. The filing itself is usually free.
4. Attend the hearing. Many appeals are resolved informally — an assessor reviews your comparables and reduces the value without requiring a formal hearing. If a hearing is needed, you present your comparables and the assessor presents theirs. The board decides.

The best markets for appeals right now tend to be those where automated valuation models drove large assessment increases during rapid appreciation, because those models often lag or overshoot on the way up. If your assessment implies a value noticeably above what Redfin's or Zillow's estimate shows for your specific address, that gap is your opening argument.

One important note: a successful appeal in year one doesn't lock in the reduction forever. Assessors reassess periodically, and a future spike is possible. But a reduction is immediate cash savings — and those savings flow directly back into your escrow calculation at the next annual review.

What 'Escrow Surplus' Means and When to Expect Money Back

Not every escrow analysis results in a higher payment. Sometimes costs came in lower than projected — a tax reassessment went in your favor, or you found cheaper insurance, or the prior year's cushion was built up higher than necessary. When the analysis shows your balance will exceed the required cushion by more than $50 at any point in the projection, RESPA requires the servicer to refund the excess to you.

This refund is not optional on the servicer's part. You don't have to request it. It typically arrives as a check mailed to the address on file for your loan, or occasionally as a statement credit. The timing is usually within 30 days of the analysis being completed.

A surplus can happen in markets where property tax rates or assessed values dropped — something that occurs more rarely than increases but does happen after successful appeal processes or in declining markets. It also happens when a homeowner switches to a cheaper insurance policy mid-year and the servicer paid a lower premium than it had projected.

If you believe you're due a surplus but haven't received anything, check the timing: the refund comes after the analysis, and the analysis is triggered by your loan anniversary date (the date your loan originated), not the calendar year. A loan that closed in July will have its escrow analysis run around July of each year, not in January. Call your servicer if you're past 30 days from the analysis date and haven't received the refund.

One thing to watch: some homeowners receive a surplus check and spend it, then are surprised when next year's analysis shows a shortage — because the same underlying cost increase that generated the temporary surplus eventually works through the system. A surplus one year doesn't guarantee stability the next, particularly in markets where insurance or tax costs are still in motion.
