When Maria Gonzalez closed on a three-bedroom house outside Houston in 2021, her monthly mortgage payment was $1,640. By spring 2026, it had climbed to $1,940. Her interest rate never changed. She never refinanced. What changed was her property-tax bill. Harris County reassessed her home’s value upward twice in three years, and the escrow account her lender uses to collect for taxes absorbed every dollar of the increase. “I picked a fixed rate on purpose,” Gonzalez told Houston’s KHOU-TV in a segment that aired in April 2026. “Nobody told me the ‘fixed’ part only covers half the payment.”
She is far from alone. Federal data confirms that property-tax collections by state and local governments have reached record highs nationally, and the increases are filtering into millions of mortgage statements through a mechanism most borrowers barely think about until the letter arrives: the annual escrow recalculation.
Record collections, record bills
The U.S. Census Bureau’s Quarterly Summary of State and Local Tax Revenue shows that property-tax collections climbed to new peaks through the third quarter of fiscal year 2025, the most recent period with published data. Local governments depend on property levies more than any other single revenue source, and the upward trend reflects two forces working together: assessed values that surged alongside post-pandemic home prices, and rate adjustments adopted by counties, cities, and school districts to cover rising labor, pension, and infrastructure costs.
Even where elected officials have avoided headline rate hikes, valuation increases have quietly expanded tax bases. A home that sold for $280,000 in 2019 and is now assessed at $410,000 generates far more revenue at the same millage rate. Multiply that across an entire jurisdiction and the aggregate numbers climb fast.
New Jersey remains the starkest example. Data published by the state’s Department of Community Affairs shows the statewide average property-tax bill crossed $10,000 for the first time in tax year 2024, continuing a trend that has made the state a perennial outlier. But the pressure is not confined to the Northeast. Texas, Illinois, Connecticut, and New Hampshire all carry effective tax rates well above the national median, according to the Census Bureau’s American Community Survey, and fast-appreciating Sun Belt markets are catching up as reassessments land.
How escrow turns a tax hike into a bigger mortgage payment
Most homeowners with a mortgage never write a check directly to their county tax office. Instead, their lender or servicer collects a portion of the estimated annual tax-and-insurance bill each month and holds it in an escrow account. When the bill comes due, the servicer pays it on the borrower’s behalf.
Federal rules spelled out in Regulation X (Section 1024.17), enforced by the Consumer Financial Protection Bureau, cap the cushion a servicer can hold at one-sixth of estimated annual disbursements. That cap protects borrowers from excessive reserves but also means the escrow balance tracks real costs closely. When property taxes or insurance premiums jump, the servicer must recalculate and collect more each month.
The arithmetic is simple, but the result can still blindside people. A homeowner whose annual tax bill rises by $1,500 will see roughly $125 added to each monthly statement from the escrow adjustment alone. If the servicer had to advance money to cover a shortfall in the prior year because the old estimate was too low, the borrower may also owe a deficit repayment spread over 12 months, temporarily compounding the increase. A $200 or $300 jump on a payment the borrower believed was locked in can feel like a stealth rate hike, even though the loan’s contract terms have not changed at all.
Insurance is piling on
Property taxes are not the only line item pushing escrow payments higher. Homeowners insurance premiums have risen sharply in many states, driven by catastrophic weather losses, reinsurance costs, and carrier pullbacks from high-risk markets. The National Association of Insurance Commissioners reported that homeowners insurance loss ratios deteriorated significantly in recent years, and S&P Global Market Intelligence data showed average premiums nationally rising by double-digit percentages between 2022 and 2025. States like Florida, Louisiana, Texas, and California have been hit hardest.
Because insurance is collected through the same escrow mechanism as taxes, borrowers in those states can face a double hit: higher taxes and higher premiums arriving in the same annual escrow analysis. The CFPB’s consumer guidance on why mortgage payments change makes clear that both increases flow through escrow identically. For households already stretched by elevated grocery, utility, and childcare costs, the combined escrow adjustment can represent the single largest year-over-year increase in their monthly budget.
Reassessment timing creates uneven shock
Not every homeowner feels the squeeze at the same time. States and counties reassess property values on wildly different schedules. Some jurisdictions, including parts of New York, reassess annually. Others, including parts of Ohio and Georgia, operate on cycles of three to six years. When a jurisdiction that has not updated values since before the pandemic finally reassesses, the correction can be enormous, producing a single-year tax increase that dwarfs what a homeowner in an annual-reassessment state would experience.
That uneven timing matters for household budgets and, potentially, for mortgage performance. A borrower who absorbs gradual $40-per-month escrow bumps over several years is in a very different position than one who gets a $250 increase all at once. Housing counselors in states with long reassessment gaps have reported rising call volumes from borrowers blindsided by their new payment amounts, though no published study has yet isolated the relationship between reassessment cycles and subsequent mortgage delinquency with enough precision to draw firm conclusions.
What homeowners can actually do
The escrow system is largely automatic, but homeowners are not powerless. Several steps can soften the blow or, in some cases, reduce the underlying tax bill:
- Challenge the assessment. Every state offers a formal appeals process. If comparable homes in the neighborhood are assessed lower, or if the assessor’s records contain errors (wrong square footage, an extra bathroom that does not exist), a successful appeal can roll back the valuation and the tax bill with it. Deadlines vary by jurisdiction, so checking with the local assessor’s office early in the tax year is critical.
- Claim every exemption available. Homestead exemptions, senior freezes, veteran exemptions, and disability exemptions can meaningfully reduce the taxable value of a primary residence. Many homeowners qualify but never file the paperwork. Texas, for example, raised its homestead exemption to $100,000 under Proposition 4, approved by voters in November 2023, yet county appraisal districts report that some eligible homeowners still have not updated their filings.
- Review the escrow analysis letter carefully. Servicers are required to send an annual escrow-analysis statement. It should itemize projected taxes and insurance, the new monthly escrow amount, and any shortage or surplus. Errors happen. Borrowers who spot a miscalculated tax projection can request a correction from their servicer.
- Ask about spreading a shortage. When an escrow analysis reveals a deficit, federal rules allow borrowers to repay shortages over 12 months rather than in a lump sum. Some servicers default to the spread, but others may need to be asked.
- Consider dropping escrow (if eligible). Borrowers with substantial equity and a strong payment history can sometimes request that the lender remove the escrow requirement, allowing them to pay taxes and insurance directly. This shifts the budgeting responsibility to the homeowner but eliminates the surprise of a recalculated payment. Lender policies and state laws vary, and some loan programs (FHA, for instance) do not permit escrow waivers.
A few states are trying to help
Legislators in several states have responded to constituent pressure with targeted relief. Beyond Texas’s expanded homestead exemption, Illinois has debated freezing assessed values for longtime owner-occupants, and Florida lawmakers have revisited the Save Our Homes cap to determine whether its 3% annual growth limit still provides adequate protection given current insurance costs. Whether these measures keep pace with the underlying cost pressures remains an open question, and many proposals stall before reaching a governor’s desk.
At the federal level, no broad property-tax relief program exists. Property taxation is a state and local function, and Congress has shown little appetite to intervene directly. The $10,000 cap on the federal deduction for state and local taxes (SALT), in place since the 2017 Tax Cuts and Jobs Act, continues to limit the degree to which high-tax-state homeowners can offset their bills on their federal returns.
What the data still does not show
For all the clarity on the national trend, important details remain murky. The Census Bureau’s quarterly release reports aggregate revenue by state and tax type, but county-level assessment growth rates for 2025 have not been broken out in the publicly available data files. Without that granularity, pinpointing which metro areas experienced the sharpest single-year jumps is difficult.
Mortgage servicers, meanwhile, have not disclosed data on the volume or size of escrow-shortage notices sent during the current adjustment cycle. The CFPB requires annual analyses for most escrowed loans, and many servicers complete them in the first quarter, meaning millions of recalculated payment letters likely arrived between January and April 2026. Yet no public dataset tracks how many households received increases above a given threshold, how many fell behind on payments as a direct result, or how the burden breaks down by income level or geography.
That information gap matters for policymakers weighing reassessment reforms and homeowner-assistance programs. It also matters for borrowers trying to plan ahead. As of mid-2026, the national picture tells a clear but incomplete story: property-tax collections are at record highs, escrow accounts are passing those costs through faithfully, and the mortgage payment millions of Americans treat as their most predictable monthly expense is becoming less predictable by the year.
