The county mails one bill a year. If it gets lost, misfiled, or you forget — the penalty starts the day after the deadline. Set an email reminder weeks in advance so the bill gets paid on time, not 10% over.
Done in seconds. No sign-up required.
The penalty doesn't scale with how late you are. It applies the moment you miss.

Property tax is a once-or-twice-a-year payment. The interval is long enough that it falls out of routine attention between bills. By the time the next one is due, twelve months of life have happened on top of it. Most people don't have a system for catching it again.
The structural failure points are predictable. If your mortgage is paid off, no escrow account is paying the county for you anymore. If your bill is mailed and you've moved, it may not arrive at all. If you only had escrow during a refinance window, that arrangement ended quietly and the responsibility shifted back to you. None of these are noticed until the delinquency notice arrives.
The bill itself doesn't help either. Counties typically send one paper notice and a single email if you opted in. No follow-up. No reminder a week before. If the first notice gets buried under junk mail, you find out the next time you check your mailbox — usually after the penalty applies.
Set the date your county tax is due, get an email a few days before it, and follow-ups if you don't mark it paid. The payment itself still happens through your county portal or by check — BoldRemind just makes sure you don't forget the date.
Check your most recent tax bill or your county tax collector's website. Many counties bill in two installments, fall and spring.
Enter your email and the date. Recurring annual reminder, so you only do this once. No account, no app, no password.
Emails 7 days, 3 days, and 1 day before the date — plus a few follow-ups if you don't mark it done. Enough lead time to actually pay.
A late payment is rarely a small problem. The penalty stacks fast.
Many states apply a flat penalty (often 10%) the moment the delinquent date passes. There's no grace period, no 30-day window in most jurisdictions.

It depends on your county. Most US counties bill annually or in two installments (typically fall and spring). Check your most recent tax bill or your county tax collector's website for your exact due date, then set a reminder for two to three weeks before it.
Only if you have an escrow account through your mortgage. The lender collects 1/12 of your annual taxes with each payment and pays the county on your behalf. If you've paid off your mortgage or never had escrow, you pay the county directly and the responsibility is entirely yours.
Most counties mail a single tax bill once a year. Some let you sign up for an email reminder specific to that jurisdiction. There's no national reminder service, no follow-up if the bill gets lost in the mail, and no second notice until you're delinquent.
Set it two to three weeks before the due date. That gives you enough time to confirm the amount, write a check or schedule an online payment, and account for any banking delays. A same-week reminder leaves no margin if something goes wrong.
In many states a flat penalty kicks in the moment the deadline passes. California, for example, applies a 10% penalty on the unpaid installment the day after the delinquent date. Some states use a smaller monthly interest charge instead. Either way, one day late often costs the same as one month late.
Yes. Property tax dates repeat each year on the same county schedule, so a recurring annual reminder works well. Set the date for your county's due date and BoldRemind will email you a few days in advance every year.
Free. No account. Takes 30 seconds. You'll get an email days before your county due date — and follow-ups if you don't mark it paid.
