Hillsborough County Sees Largest Property Tax Increase in Years — Here’s Why
If your 2025 property tax bill made your jaw drop, you’re not imagining things. Hillsborough County homeowners are facing one of the largest property-tax increases in recent years, driven by skyrocketing property values and the passage of a new voter-approved school tax.
Let’s break down what’s behind the jump — and what it means for your bottom line.
1. Soaring Property Values Are Catching Up
Tampa Bay’s housing market has been on fire for years, and now the tax rolls are catching up.
The Hillsborough County Property Appraiser reassesses property each January 1 based on fair-market value. With home prices climbing year after year, the county’s overall taxable base has expanded dramatically.
Even if local tax rates (called “millage rates”) didn’t change much, your taxable value likely increased — and that means a higher bill.
Investment properties, second homes and rentals feel it the most because they aren’t protected by the Save Our Homes 3% cap that shields homesteaded properties.
2. New Voter-Approved School Tax Adds to the Bill
In November 2024, Hillsborough County voters passed a new one-mill ad valorem tax to fund public-school salaries and programs. Starting July 2025, property owners will pay $1 for every $1,000 of assessed value — a major new addition to annual tax bills.
According to school officials, this will raise tens of millions of dollars each year and help fund teacher and staff raises averaging around $6,000. That’s good news for educators — but it’s another reason why homeowners and investors alike are seeing record-high tax totals.
3. Local Governments Are Spending More to Keep Up With Growth
Hillsborough County’s population continues to surge. More residents mean more roads, more fire stations, more deputies, and more classrooms. To fund that growth, county and municipal budgets have expanded. Even small increases in millage rates for public safety or infrastructure add up when applied to thousands of higher-value properties.
4. Homestead Caps and Exemptions Don’t Always Apply
The Save Our Homes amendment limits annual assessment increases on a primary residence, but any change of ownership resets that cap. If you bought or transferred property recently, expect your assessed value to “un-cap” to full market value — which can mean a sharp jump.
Landlords and investors don’t receive homestead protection, making them more exposed to rising assessments. Still, non-homestead properties are capped at a 10% annual increase in taxable value.
5. What Property Owners Can Do
- Review your TRIM notice: Each August, check your proposed assessed value and millage rates. If something looks off, you can appeal through the Value Adjustment Board.
- Confirm your exemptions: Ensure your homestead, senior or military exemptions are correctly applied.
- Budget accordingly: Rising property taxes may cause your lender to adjust your escrow account. Plan for a possible increase of a few hundred dollars per year to avoid surprises.
- You can also save by paying your property taxes early: Receive 4% off in November, 3% in December, 2% in January, and 1% in February — but remember, taxes are due by March 31, and any unpaid bills become delinquent on April 1 with added fees.
Bottom Line
The 2025 tax year marks the largest property-tax increase Hillsborough County has seen in years. Between skyrocketing property values, expanding local budgets, and the new voter-approved school tax, property owners are feeling the impact.
If you own property in Tampa, Valrico, Riverview, or anywhere across Hillsborough County, now’s the time to double-check your exemptions, understand your TRIM notice, and plan ahead for next year’s bill.
If your tax bill feels like it’s getting out of hand, it might be the right time to take advantage of today’s strong market and high home values. Considering selling or refinancing your home? Get an Instant Property Valuation now!
