Delinquent Real Estate Taxes: Penalties, Liens and How to Check a Parcel
Delinquent real estate taxes add penalties and interest, keep a first lien on the parcel and can end in a sale. Texas and Arizona rates, plus where to look one up.
Quick answer
Delinquent real estate taxes are property taxes not paid by the date the law sets. From that date the bill grows with penalties or interest, the tax lien stays on the parcel ahead of other claims, and the taxing authority can eventually sell a tax certificate or foreclose. Each state sets its own dates and rates.
What are delinquent real estate taxes?
A property tax bill has a due date and a delinquency date, and they are not always the same day. Texas, for example, treats taxes as due when the bill is received but delinquent only "if not paid before February 1 of the year following the year in which imposed", according to the Texas Tax Code section 31.02 text on Texas.Public.Law. Once a tax is delinquent, it is on what many offices call the delinquent tax roll or delinquent tax list: the office's record of accounts that are past due.
This article covers what happens after that point, using statutes and official county pages in Texas, Florida and Arizona, plus the Cook County and Maricopa County treasurer sites. For the basics of the lien itself, see tax lien. For how the bill and the parcel number work, see property tax records lookup.
Definition
Delinquent real estate taxes — Property taxes that remain unpaid after the delinquency date set by state law, which start to carry penalties or interest and can lead to a tax sale.
When do unpaid property taxes become delinquent?
The date depends on the state. The table lists what the statutes we fetched say. Other states and counties set their own dates, so always confirm on the local treasurer or tax collector page.
| State | Delinquent when | Source |
|---|---|---|
| Texas | If not paid before February 1 of the year after the tax year (Tax Code 31.02), with exceptions such as split payment and postponement | texas.public.law |
| Florida | On April 1 following the year the taxes were assessed, or 60 days after the original tax notice is mailed, whichever is later (Fla. Stat. 197.333) | Online Sunshine |
| Arizona | First half is delinquent after November 1 at 5:00 p.m., second half after May 1 at 5:00 p.m. (A.R.S. 42-18052); totals of $100 or less are delinquent after December 31 | azleg.gov |
What penalties and interest apply to unpaid property taxes?
Texas adds a penalty and interest. Section 33.01 sets a penalty of six percent for the first calendar month a tax is delinquent, plus one percent for each additional month before July 1. A tax still unpaid on July 1 carries a total penalty of twelve percent. Separately, interest accrues at one percent for each month or portion of a month the tax stays unpaid (Texas Tax Code 33.01, Texas.Public.Law).
Both continue to accrue, the statute says, "regardless of whether a judgment for the delinquent tax has been rendered." The same section sets higher penalties for taxes that become delinquent because a homestead exemption was wrongly claimed and later cancelled.
Arizona uses interest only. Under A.R.S. 42-18053, taxes bear interest from the time of delinquency at sixteen percent per year, simple, until paid, and a fraction of a month counts as a whole month. Interest is not collected if the delinquency came from an error by the county assessor or treasurer, or if the full year tax is paid on or before December 31 of the tax year (A.R.S. 42-18053).
Florida's Chapter 197 sets its own interest and cost rules for delinquent accounts. We did not fetch the rate schedule, so check the figure on your county tax collector's page rather than relying on a rule of thumb.
How much does a delinquent bill grow? A worked example
The table applies the Texas formula to an invented $4,000 bill that stays unpaid after February 1. It is an illustration only: real bills are split among taxing units and may carry collection costs that the statute text above does not show.
| Month paid | Penalty | Interest | Combined | Amount on $4,000 |
|---|---|---|---|---|
| February | 6% | 1% | 7% | $280 |
| April | 8% | 3% | 11% | $440 |
| June | 10% | 5% | 15% | $600 |
| July | 12% | 6% | 18% | $720 |
Does a delinquent property tax become a lien?
Yes, and the lien usually exists before the tax is even late. In Texas, a tax lien attaches on January 1 of each year to secure the taxes, penalties and interest ultimately imposed for that year (Tax Code 32.01). In Florida, taxes are "a first lien, superior to all other liens," running from January 1 of the year the taxes were levied until paid or barred (Fla. Stat. 197.122).
The Legal Information Institute adds the general point that a tax lien takes precedence over a mortgage, which is why a lender may pay the tax debt itself and seek reimbursement (LII, tax lien). For how this fits with other claims, see lien on a house.
What happens if you do not pay delinquent property taxes?
The delinquency date passes
The account moves to the delinquent list and penalties or interest start, as in the Texas and Arizona rules above.
The lien stays and the balance grows
The lien that attached at the start of the tax year stays on the parcel. In Texas, penalty and interest keep accruing even after a court judgment.
The taxing authority collects
In Texas, a taxing unit may sue at any time after a tax is delinquent to foreclose the lien, enforce personal liability for the tax, or both (Tax Code 33.41). In Florida, the tax collector has the authority and obligation to collect delinquent taxes, interest and costs by sale of tax certificates on real property (Fla. Stat. 197.332).
A sale or certificate sale may follow
Where a tax certificate is sold, as in Florida, the property can be redeemed by paying what is owed before a deed is issued. See tax sale and, for New York City, the NYC tax lien sale explained.
Redeeming before a tax deed
How do you check if a property has delinquent taxes?
Use the tax office that bills the parcel. These are the official entry points we confirmed on the offices' own pages. A delinquent tax lookup is only as current as the office's data, so note the date shown.
| County | Office | What the page offers |
|---|---|---|
| Cook County, Illinois | Cook County Treasurer | Menu items for "Search to See If Your Property Has Delinquent Taxes" and a notice on how to avoid the December 15, 2026 tax sale |
| Harris County, Texas | Harris County Tax Office | A "Search Delinquent Account" item and a "Delinquent Property Tax Sales" item |
| Maricopa County, Arizona | Maricopa County Treasurer | Search by parcel, name, address or VIN, plus a "View the Map of Delinquent Taxes" link |
How do you run a delinquent tax search step by step?
Get the parcel number
Use the parcel or property index number, not only the street address. Property tax records lookup explains where to find it.
Search the treasurer or tax collector
Pick the county office from the table above, or your own county's office, and search by parcel number. Check the tax years listed, not just the latest bill.
Look for prior years and sale notices
Cook County lists a "Lists of Properties with Delinquent Tax Year 2023 Taxes" item on its home page, which shows that delinquency can run back several tax years before a sale.
Compare with the recorded documents
The tax office shows the tax account. Liens, mortgages and judgments are in the recording office. See how to check for liens on a property.
What does a delinquent tax lookup not show?
A paid-up account only means the tax office has no unpaid tax on file. It does not show mortgages, judgment liens or ownership problems. Those sit in the county recording records.

Frequently asked questions
- What is the delinquent tax roll?
- The delinquent tax roll, also called the delinquent tax list, is a local tax office's record of accounts that were not paid by the delinquency date. Offices publish it differently: some offer a searchable account lookup, others post lists by tax year. Check your own county office.
- When do unpaid property taxes become delinquent in Texas?
- Under Tax Code 31.02, Texas taxes are delinquent if not paid before February 1 of the year following the year they were imposed. Exceptions exist for split payments and postponements. Penalty and interest then start under section 33.01.
- How much interest do unpaid property taxes accrue in Arizona?
- A.R.S. 42-18053 says taxes bear interest from delinquency at sixteen percent per year, simple, and a fraction of a month counts as a whole month. Interest is not collected if the county assessor or treasurer caused the delinquency.
- Can you lose your house over unpaid property taxes?
- Yes. In Texas a taxing unit may sue to foreclose the tax lien, and in Florida the tax collector sells tax certificates that can lead to a tax deed if the property is not redeemed. The process and timing differ by state, so ask the local tax office.
- How do I do a delinquent tax lookup on a property?
- Go to the county treasurer or tax collector that bills the parcel and search by parcel number. Cook County, Harris County and Maricopa County each list a delinquent search or map on their official sites. Check every tax year shown.
- Is a delinquent tax lien ahead of my mortgage?
- Often, yes. Florida statute 197.122 calls property taxes a first lien superior to all other liens, and the Legal Information Institute notes that a tax lien takes precedence over a mortgage. Check your own state's rule.
- Does a delinquent tax search show all liens on a property?
- No. It shows the tax account at the tax office. Mortgages, judgments and other liens are recorded with the county recorder or clerk, so a separate records search is needed to see them.
