Why did my mortgage payment go up after my Tarrant County tax bill?
Because your servicer paid the county's higher bill out of your escrow account, then ran the annual escrow account analysis that federal rule 12 CFR 1024.17(c)(3) requires at the end of every escrow year, and reset your monthly payment to cover next year's taxes and insurance. The new amount is next year's projected bill divided by twelve, plus, if the account came up short by a month's escrow payment or more, the shortage spread in equal installments over at least 12 months (Sec. 1024.17(f)(3)(ii)); the shortage is measured against a target balance that may include a cushion the rule caps at one-sixth of the year's disbursements (Sec. 1024.17(c)(1)(ii)). Two increases arrive in one letter and only the first one is a new tax, and the letter's month depends on the loan: the escrow year runs from the initial payment date (Sec. 1024.17(b)), not the calendar. For a Fort Worth house the 2026 adopted city rate is $0.70565 per $100 of taxable value, up from $0.670000 (Tarrant County entity rate portal, read October 13, 2026), and the county says 2026 statements begin mailing by mid-October.
The Annual Reset Is Required, Not Optional
Sec. 1024.17(c)(3): the servicer "must conduct an escrow account analysis at the completion of the escrow account computation year to determine the borrower's monthly escrow account payments for the next computation year." Sec. 1024.17(i): you get the annual escrow statement "within 30 days of the completion of the escrow account computation year," and the analysis has to happen before the statement goes out (the statement duty is suspended while a loan is more than 30 days overdue, in foreclosure, or in bankruptcy, Sec. 1024.17(i)(2)). The computation year starts at the loan's initial payment date (Sec. 1024.17(b)), so the letter's month differs loan to loan. The cushion is the only padding the rule allows, and Sec. 1024.17(c)(1)(ii) caps it: "no greater than one-sixth (1/6) of the estimated total annual payments from the escrow account." Two months of taxes and insurance, held as a balance inside the target the account is measured against, not charged as a separate line. A servicer holding more than that is holding more than the rule permits.
A Shortage Is Spread Over at Least a Year
If the account balance is below its target at the analysis, that gap is a shortage. Sec. 1024.17(f)(3)(ii), for a shortage of one month's escrow payment or more: the servicer "may require the borrower to repay the shortage in equal monthly payments over at least a 12-month period." For a shortage under one month's payment, Sec. 1024.17(f)(3)(i) also lets the servicer ask for it within 30 days. So the reset letter stacks two things: the higher monthly estimate for next year's bill, and, if the servicer chooses to collect it, last year's overrun spread over at least twelve months (the overrun measured against a target that already includes the cushion; the rule also lets a servicer leave a shortage alone). The Consumer Financial Protection Bureau says it in one line: "if your monthly mortgage payment includes the amount you have to pay into your escrow account, then your payment will also go up or down if your taxes or premiums go up or down" (CFPB, page last modified May 21, 2026).
A Surplus Comes Back to You
The rule runs both ways. Sec. 1024.17(f)(2)(i): if the analysis shows a surplus, "the servicer shall, within 30 days from the date of the analysis, refund the surplus to the borrower if the surplus is greater than or equal to 50 dollars ($50)." Under $50 the servicer may refund it or credit it against next year's payments. Sec. 1024.17(f)(2)(ii) conditions the refund on the loan being current. If your taxable value fell, or an exemption was added, the surplus is yours, not the servicer's float.
What Drove the Bill: the Adopted 2026 Rates
The county's entity portal lists the adopted 2026 rates per $100 of taxable value (read October 13, 2026): Tarrant County $0.186000; Tarrant County Hospital District $0.159000; Tarrant County College $0.120000; City of Fort Worth $0.705650; City of Saginaw $0.586649; Eagle Mountain-Saginaw ISD $1.285700, subject to the voter-approval election on November 3, 2026; Keller ISD $1.085200. Fort Worth's budget page says the FY2027 budget "will raise more revenue from property taxes than last year's budget by an amount of $39,728,860, which is a 4.98 percent increase" (read October 13, 2026). Your taxable value times each of those rates is the bill your servicer paid. Compare the county's total to the projected-taxes line on last year's escrow statement; the gap is the shortage that can be spread over your next twelve or more payments.
The Deadline Has a Sunday in It
If you do not escrow, the bill is yours to time. Texas Tax Code Sec. 31.02(a): taxes "are due on receipt of the tax bill" and are delinquent "if not paid before February 1." The Tarrant County Tax Office puts it as a postmark rule, January 31, and adds the line that catches absentee owners: "Failure to receive a property tax statement does not waive penalty and interest" (Tax Office FAQ, read October 13, 2026). January 31, 2027 is a Sunday, so under Sec. 1.06 a payment made Monday, February 1, 2027 is timely. The half-payment option under Sec. 31.03, where offered: first half by November 30 marked Half Payment, second half by June 30, no penalty or interest. Quarter payments are a separate option with their own eligibility rules (Secs. 31.031, 31.032).
Common Questions
- Can my servicer keep more than two months of cushion in escrow?
- No. 12 CFR 1024.17(c)(1)(ii) caps the cushion at one-sixth of the estimated total annual payments from the account, which is two months. The cushion sits inside the target balance; if the annual statement shows a cushion larger than that, ask the servicer to explain the arithmetic.
- Can I pay an escrow shortage in a lump sum instead of monthly?
- Usually yes if you ask; the rule sets what the servicer may require, not what you may offer. Sec. 1024.17(f)(3)(ii) lets the servicer require at least a 12-month spread for a shortage of one month's payment or more, and (f)(3)(i) lets it require repayment within 30 days for a smaller one. Paying it off keeps the new monthly amount at next year's estimate only.
- Why did my payment change when the tax rate went down?
- Because the bill is rate times taxable value, and value moved. A lower rate on a higher assessed value still produces a bigger bill, and a bigger bill produces a shortage at the analysis. The Fort Worth rate went up for 2026 ($0.670000 to $0.705650), but the value line on the statement is usually the larger mover.
- Does the 20% appraisal cap affect my escrow if the house is a rental?
- For 2026, yes: Tax Code 23.231 limited the increase in a qualifying rental's appraised value to 20 percent a year. Subsection (k) says the section expires December 31, 2026, and the Tarrant Appraisal District says it is authorized only for the 2024, 2025, and 2026 tax years. Unless the Legislature extends it, the 2027 appraisal on a rental is uncapped, and the 2027 bill is what the 2028 escrow analysis will be built on.
- When do 2026 Tarrant County tax statements mail?
- The Tarrant County Tax Office said 2026 statements begin mailing by mid-October, after its conversion to a new online system (notice read September 21, 2026). Its FAQ says statements are usually mailed the first week of October. Not receiving one does not waive penalty and interest.
