Key takeaways
- Union County's effective property tax rate is 0.58%, lower than the Florida figure of 0.76%. It ranks #56 of 67 counties (1 = highest).
- From the 2009–2013 survey to 2020–2024, the median tax bill rose 17% ($839 → $980) while the median home value rose 90%, so the effective rate went from 0.94% to 0.58%.
- The median bill equals 1.5% of the county's median household income ($64,146), compared with 3.7% statewide. That is #62 of 67 on this burden measure.
- Local governments levied an average of 16.72 mills in 2025 (#18 of 67). A new homesteaded buyer of a median-value home ($169,500) would owe roughly $2,118 a year at that rate, 2.2× the current median bill, because long-time owners' assessments are held down by Save Our Homes while a sale resets the assessment to market value.

What is the property tax rate in Union County, FL?
There is no single rate. Homeowners paid a median $980 on a median home value of $169,500, an effective rate of 0.58% (Census ACS 2020–2024). The average levy was 16.7165 mills in 2025 (Florida Department of Revenue), but each parcel's millage depends on its city and districts.
How much is property tax on a $300,000 home in Union County?
For a homesteaded home assessed at $300,000, the county's average 2025 millage gives roughly $4,300 a year in ad valorem taxes, before any non-ad valorem assessments. Without homestead the estimate is about $5,015.
Is Union County property tax high for Florida?
Its effective rate ranks #56 of 67 Florida counties and its median bill ranks #57 (1 = highest). The statewide effective rate is 0.76%.
Why is my bill different from the median?
Florida assessments for homesteaded homes can rise at most 3% a year (or the CPI change, if lower) under Save Our Homes, and they reset to market value after a sale. Non-homestead property has a 10% cap on non-school levies. City millage, special districts, exemptions and non-ad valorem fees all change individual bills.
Where do I check my actual tax bill?
Check the Union County property appraiser for assessed value and exemptions, and the Union County tax collector for the bill. This site shows statistical estimates only.
