Flat Tax Rate, Higher Tax Revenue: Why Pinellas County's Budget Could Grow Again

Pinellas County has officially begun work on its next fiscal year budget, and while commissioners have signaled they intend to keep the county's property tax millage rate unchanged, that does not necessarily mean property tax collections will remain flat.

In Florida, property tax revenue is driven by two factors: the millage rate established by local governments and the taxable value of property throughout the county. As home values, commercial real estate values, and new construction increase, local governments collect more revenue even if the tax rate itself never changes.

That distinction is often lost in public discussions.

A flat millage rate does not produce flat tax revenue. Instead, it generally results in higher collections because the taxable property base continues to grow each year.

Understanding the Rollback Rate

Florida's Truth in Millage (TRIM) process includes what is known as the "rollback rate." This is the millage rate that would generate approximately the same amount of property tax revenue from existing properties as the previous year, excluding new construction.

When a local government adopts a millage rate above the rollback rate, it is choosing to collect additional revenue from increases in property values.

Historically, Pinellas County's taxable property values have increased substantially over the past several years. While appreciation has moderated from the rapid gains experienced during the post-pandemic housing market, countywide taxable values have continued to trend upward through a combination of appreciation, ownership changes, commercial growth, and new development.

As a result, maintaining the current millage rate would likely produce another increase in county property tax revenue for the upcoming fiscal year.  They've had record spending bills for several years in succession, and their current plans are to keep the increased record spending trend intact for the next fiscal year.  

More Revenue Without Raising the Rate

For many homeowners, particularly those protected by Florida's Save Our Homes assessment cap, taxable values increase more slowly than market values. However, countywide revenue is also driven by non-homestead property, commercial real estate, rental housing, newly constructed properties, and homes that reset to market value following a sale.

Because of those factors, total taxable value across Pinellas County has historically grown faster than the average homesteaded property's taxable value.

Even a modest countywide increase in taxable value can translate into tens of millions of dollars in additional property tax revenue when applied across the county's tax base.

Budget Direction Signals Continued Spending Growth

During Tuesday's budget discussions, commissioners indicated that maintaining the current millage rate—not pursuing a rollback rate—was the preferred direction as staff prepares the proposed budget for Fiscal Year 2027. The budget process will continue through the summer before public hearings are held and a final budget is adopted.

If that approach remains unchanged, Pinellas County would be positioned to collect more property tax revenue than it did during the current fiscal year, even without increasing the tax rate itself.  This sleight of hand is how they tell you they held the line on taxes while supporting record spending at the County level year over year.  Meanwhile, the population in Pinellas County is decreasing year over year.  Less people are paying more taxes.  

Whether that additional revenue ultimately results in another record county budget will depend on final certified property values, spending priorities, and budget decisions made during upcoming public hearings. Based on the commission's current direction, however, no rollback rate has been placed on the table, signaling an expectation that county spending will continue to grow alongside property tax collections.

For taxpayers, the distinction is important. A government can accurately state that it did not raise the millage rate while still collecting significantly more property tax revenue because the tax base itself has expanded. Understanding that difference is essential to evaluating local budgets and the long-term trajectory of government spending.

There should be no surprise that the Pinellas County Commission is planning on another record spending bill.
