Short answer: Miami-Dade publishes delinquent real property taxes ahead of its annual certificate sale, and the tax collector is the office that holds the data. The list is large, so filtering matters more here than in a small county.
- The tax collector holds it, not the property appraiser.
- Florida runs a certificate sale, so the annual auction sells the debt, not the property.
- Delinquency is advertised before the sale, which is what makes the list public.
- Filter hard. A county this size produces a file that is unusable raw.
Miami-Dade is one of the largest counties in the country, which makes its delinquency list both valuable and unusable in raw form. The value is in the filtering, not the download.

Where the data lives
| Office | What it holds |
|---|---|
| Tax Collector | Who has not paid, amounts owed, delinquency years, certificate sale information. Start here. |
| Property Appraiser | Ownership of record, assessed values, mailing addresses, property characteristics. |
| Clerk of Court | Recorded documents, liens, probate and foreclosure filings. |
People routinely start with the Property Appraiser because it is the better known search. It will not tell you who is delinquent. Go to the Tax Collector for that, then come back to the Appraiser to enrich what you find.
Getting the list
- Look for the annual tax certificate sale information on the Tax Collector’s site. Florida counties run these on online platforms and publish bidder and parcel information ahead of the sale.
- Find the advertised delinquency list. Florida requires delinquent real property taxes to be advertised before the sale, which is what puts this in the public domain.
- Ask for a data file. Large counties often supply the roll in a machine readable format rather than only as an advertisement.
- Capture the delinquency year per parcel, which is the field that does the actual work.
- Enrich from the Property Appraiser for owner mailing address and assessed value.
- Check the Clerk for probate and foreclosure filings on anything that looks promising.
Florida’s certificate sale cycle runs to a statutory calendar tied to when taxes become delinquent in the spring. Work backwards from the sale date, because the advertised list appears in the weeks before it and that is your freshest free snapshot.
Filtering a county this large
A raw Miami-Dade delinquency file is tens of thousands of rows. Working it without filters is how people conclude the list does not work.
- Two or more years delinquent. One year is dominated by escrow timing and oversight.
- Mailing address outside the county, or simply different from the property address. The strongest single filter available.
- Exclude condominiums initially, or handle them separately. Miami-Dade has enormous condo inventory with association dues, special assessments and rules that change the analysis completely.
- Exclude institutional and government owners, which fill any urban county file.
- Deduplicate by owner. Portfolio holders are common here and appear many times.
- Sanity check assessed value to drop unbuildable slivers and common area parcels.
Condominiums deserve genuine caution in this market. Unpaid association dues, special assessments for structural work, and reserve requirements introduced in Florida after 2021 can dwarf the tax delinquency itself. Understand the association’s finances before you get interested in the parcel.
What to actually do with it
Remember that Florida sells certificates, so the auction transfers the debt rather than the property. For anyone buying houses, the list is not an auction shopping list. It is a lead list of owners with a public deadline.
- Mail first. The tax mailing address is on the roll and costs nothing to use.
- Skip trace the absentee, multi year records that survive your filters, not the whole file.
- Expect heirs on older delinquencies, which is where relative data earns its cost.
- Lead with the property, not the debt. Opening with what they owe reads as a collection call.
Frequently asked questions
Where do I get the Miami-Dade tax delinquent list?
From the Miami-Dade Tax Collector, which holds delinquency data and runs the annual tax certificate sale. Florida requires delinquent real property taxes to be advertised before the sale, which makes the list public.
Does Miami-Dade sell properties for back taxes?
Not at the annual sale. Florida sells tax lien certificates, so that auction transfers the tax debt. A certificate holder may later apply for a tax deed, which then goes to a separate auction.
Is the Miami-Dade list free?
The advertised delinquency list is public. Some counties charge a modest fee for a machine readable data file rather than a published advertisement, which is usually worth paying at this scale.
How should I filter such a large file?
Two or more years delinquent, mailing address different from the property address, institutional owners removed, deduplicated by owner, and condominiums handled separately.
Why treat condos differently in Miami-Dade?
Because association dues, special assessments and post 2021 structural reserve requirements can far exceed the tax owed. The tax delinquency may be the smallest number in the situation.
Should I bid at the certificate sale or contact owners?
If you buy houses, contact owners. The certificate sale is a yield investment in a debt. The delinquency list behind it is a lead list of people with a real deadline.
