If you have an escrow account and a property tax bill still showed up in your mailbox, the most likely explanation is that the county mailed you an informational copy while the real bill went to your mortgage servicer. But that isn’t the only possibility, and a few of the others are serious. A recent servicing transfer, a supplemental or special assessment, a shortage in your escrow account, or a plain administrative error can all leave a genuine unpaid bill sitting in your hands. Because the property owner, not the lender, is ultimately liable for the tax, it’s worth figuring out which situation you’re in before the delinquency date passes.
Check the Document Before You Do Anything
Most county tax offices send a copy of the annual assessment to every property owner on record, whether or not a servicer is set up to pay it. The mailing is a public notice of your assessed value and the tax rate for the year. Its arrival does not, by itself, mean anything went wrong.
Read the bill closely. Many of these notices carry language like “Duplicate Copy,” “Informational Notice Only,” or “This bill has been sent to your mortgage company.” If you see any of that, the original already went to your servicer and you can leave it alone. Paying it yourself in that case creates a double payment, and you’ll have to chase the county for a refund.
If there is no such notation, treat the bill as real and work through the reasons below.
Your Servicer Recently Changed
Mortgage servicing rights are bought and sold constantly, and a transfer near a tax deadline is one of the most common reasons a legitimate bill lands with you. When a loan transfers, the county tax office may still have the old servicer on file. The new servicer may not yet have your parcel data. The bill defaults to the address the county does have, which is often yours.
Federal rules require the outgoing servicer to notify you at least 15 days before the transfer takes effect, and the new servicer must notify you within 15 days after.1eCFR. 12 CFR Part 1024 Subpart C – Mortgage Servicing During the 60 days following a transfer, a mortgage payment sent to the old servicer cannot be treated as late.2Consumer Financial Protection Bureau. 12 CFR Part 1024 Regulation X – Section 1024.33 That protection covers your mortgage payment; it does not stop the county from mailing you a tax bill while the handoff sorts itself out. If a transfer notice arrived recently, call the new servicer and confirm they have your parcel number and tax identification data.
A Supplemental or Special Assessment
Your escrow is funded from last year’s tax bill projected forward. It does not automatically absorb one-time charges added mid-cycle. Two kinds of charges typically fall outside standard escrow coverage.
Supplemental assessments happen when a property is reassessed between regular tax cycles, most often after a purchase or a major renovation that increased the value. The county calculates the difference between the old assessed value and the new one and bills the gap. Servicers rarely know about these because they aren’t part of the annual billing feed.
Special assessments cover local infrastructure projects, utility improvements, or district-level charges such as community facilities fees. They are billed separately from your standard property tax and may not appear in the data your lender pulls from the county. If a special assessment shows up and your servicer didn’t pay it, the bill is yours to handle directly. Some lenders will fold future special assessments into escrow if you ask, but most won’t do it automatically.
Your Escrow Account Is Short
Escrow shortages are more common than most homeowners realize. Your servicer estimates monthly collections based on last year’s tax and insurance costs. If your property taxes went up, the municipality raised its rate, or your insurance premium jumped, the balance may not be enough when the bill comes due.
Federal law requires your servicer to analyze your escrow account at least once a year and send you a statement within 30 days of that review. The statement flags any shortage. If the shortfall is less than one month’s escrow payment, the servicer can require repayment within 30 days. If it equals or exceeds one month’s payment, you must be offered at least 12 months to repay.3Consumer Financial Protection Bureau. 12 CFR 1024.17 Escrow Accounts
The practical piece: if the servicer hasn’t advanced funds to pay the tax because of a shortage, the county doesn’t care why. The bill routes to you. Read the annual escrow analysis when it arrives. Ignoring a shortage notice can leave you with both a higher monthly payment and an unpaid tax bill accruing penalties.
An Administrative Error
Sometimes the system simply breaks. Lenders use third-party tax services that pull electronic billing data for thousands of properties. If your parcel number was recorded wrong at closing, or the county never updated the billing address after your loan closed, the automated system misses your bill and the county mails it to the address on file.
The same thing happens when a servicer fails to request the tax data on time. The bill waits at the county for an electronic pickup that never comes, and eventually the county sends it to you. None of this releases you from the tax, but it does mean the servicer made a correctable mistake.
One check worth doing: pull your Closing Disclosure from when you bought the home. Page one, under “Projected Payments,” shows whether property taxes are marked as escrowed.4Consumer Financial Protection Bureau. Closing Disclosure If taxes aren’t listed there, escrow may not be part of your loan at all.
You Might Not Actually Have Escrow
This one catches more homeowners than you’d expect. Some borrowers waive escrow at closing in exchange for a slightly lower rate or to avoid tying up cash. Others refinance into a loan without escrow and don’t fully register the change. If you have significant equity and strong credit, your lender may have offered a waiver you accepted without thinking about it.
Without an escrow account, you pay property taxes and insurance directly. The county sends the bill to you because no servicer is in the loop. If you’re not sure, check your most recent mortgage statement. It should have a section showing escrow disbursements. If that section is blank or missing, you likely waived escrow and the tax bill is fully yours.
Why You Cannot Just Wait
Escrow is a convenience, not a transfer of liability. Your servicer handles the logistics; the tax debt belongs to you. If the payment doesn’t get made for any reason, the county pursues the property owner, not the mortgage company.
Consequences escalate quickly. Unpaid property taxes trigger penalties and interest that vary by jurisdiction and can reach double digits within months. If taxes stay unpaid, the taxing authority can place a lien on your property. In some jurisdictions that lien can lead to a tax sale, where the government sells the right to collect the debt or, in the worst case, sells the property. Having escrow does not shield you from these outcomes if the bill goes unpaid.
Federal law does put obligations on the servicer. If your escrow holds the funds and you’re current on the mortgage, the servicer must pay the tax bill before any penalty deadline, and must advance funds even if the escrow balance is temporarily short, as long as your mortgage payment isn’t more than 30 days overdue.3Consumer Financial Protection Bureau. 12 CFR 1024.17 Escrow Accounts If they miss the deadline through their own error, they’re on the hook for the penalty. But while you work that out, the county’s clock keeps running against you.
How to Fix It
Start with your most recent mortgage statement. Look at the escrow section for a recent tax disbursement. If a payment matching the bill was already sent, you probably received an informational copy and can stop worrying. If no disbursement appears, treat this as a real problem.
Call the Servicer
Reach the escrow department with the tax bill in front of you. Give them the parcel number, the amount, and the deadline. If the bill was missed through a data error, the servicer can initiate a manual payment. Ask for written confirmation that payment will be made before the delinquency date, and keep it. If the account is short, ask how they plan to cover the current bill and what repayment you owe.
File a Written Notice of Error
If the servicer is unresponsive or denies responsibility, you can file a written notice of error under federal rules. Failure to pay escrowed property taxes on time is a specifically covered error. Once received, the servicer has five business days to acknowledge it and 30 business days to correct the error or explain in writing why no error occurred. They can extend the response window by 15 business days if they notify you first.5eCFR. 12 CFR 1024.35 – Error Resolution Procedures
Send the notice by certified mail. A phone call opens the conversation, but the written notice is what triggers the legal timeline and makes the servicer liable for penalties if they caused the late payment.
Update the County
Whatever the cause, call the county tax office and confirm they have your current servicer on file. If their records still list a previous servicer or point directly to you, the same problem will repeat next year.
If You Paid a Bill the Servicer Also Paid
If you paid the bill yourself and your servicer paid it from escrow too, contact the county tax office and request an overpayment refund. Have both proofs ready: your personal receipt and the escrow disbursement record. Most counties process refunds in four to six weeks. If you mailed a check that hasn’t cleared, stopping payment through your bank may be faster than waiting for the refund.
