The core commercial property tax benefits in Florida come down to four levers that change how a deal underwrites. Florida levies no state personal income tax, so rental income and personal capital gains face no state-level layer [1]. The state caps annual assessment increases on most non-homestead property at 10%, which stabilizes the tax line in your pro forma [2]. Florida exempts 80% of the just value attributable to a qualifying renewable energy source device on nonresidential real property [3]. And the federal Section 1031 like-kind exchange lets you defer federal capital gains on an investment property when you reinvest within strict deadlines [4]. This guide covers each one with the statute and the source, so you can model after-tax returns on a specific Miami asset instead of working from round numbers.

None of this is tax advice. Tax outcomes depend on entity structure, holding period, and the specific parcel, so confirm the numbers with your CPA before you act on them.

No state income tax, which raises after-tax yield

Florida does not impose a personal income tax, and it has no separate personal capital gains tax [1]. For a commercial owner holding property in a pass-through entity, that means rental income and gains on appreciation are not reduced by a state income layer the way they would be in New York or California. The advantage shows up directly in after-tax cash flow and in the net proceeds at sale.

The distinction worth keeping straight: this is a state-level benefit. Federal income tax and federal capital gains tax still apply, and entity-level taxes such as Florida's corporate income tax can apply to C corporations. The point for underwriting is that the state personal income layer that erodes yield elsewhere is simply absent here, which is part of why capital keeps moving into Brickell and the broader South Florida commercial market.

The 10% non-homestead assessment cap

Florida limits the annual increase in the assessed value of most non-homestead property, including retail, office, and industrial assets, to 10% over the prior year's assessed value [2]. The cap originated with the 2008 constitutional amendment and was extended by voters in November 2018, so it is in force through 2026 [2].

There is one limit that matters for your model: the 10% cap does not apply to school district taxes, which are still assessed on full just value [2]. So the cap shields the non-school portion of your bill, not the entire bill. The assessment also resets to full just value after a change of ownership or control, which means the buyer in a sale does not inherit the seller's capped basis. When market values in a corridor climb faster than 10% in a year, the cap keeps the non-school tax line predictable for an existing owner, which is useful when you are holding through an appreciation cycle.

The renewable energy source device exemption

An owner who installs solar or other qualifying renewable energy equipment can exclude part of the resulting value from the tax assessment. Under Florida Statute 196.182, for nonresidential real property, 80% of the just value attributable to a renewable energy source device, as defined in Florida Statute 193.624, is excluded from the assessment for devices installed on or after January 1, 2018 [3]. In plain terms, adding qualifying solar should not push your assessed value up by the full value of the system.

This is a property tax exclusion, separate from any federal energy credits, and it has specific eligibility and definitional rules. Treat it as a reason to run the numbers on a retrofit with your tax advisor, not as an automatic write-down.

Deferring federal gains with a 1031 exchange

The Section 1031 like-kind exchange is federal, not a Florida benefit, but it is central to how commercial investors here compound equity. It lets you defer federal capital gains tax when you sell investment or business real property and reinvest the proceeds into like-kind real property, rather than recognizing the gain at sale [4].

The deadlines are strict and not extendable. You have 45 days from the sale of the relinquished property to identify replacement property in writing, and you must close on the replacement no later than 180 days after the sale, or your tax return due date with extensions if earlier [4]. Miss either deadline and the exchange fails.

This matters because the alternative is a real federal bill. The top federal long-term capital gains rate is 20%, and high-income taxpayers can owe an additional 3.8% net investment income tax, for a combined 23.8% maximum federal rate on long-term gains [5]. That is the figure to model when you weigh a taxable sale against an exchange, rather than a vague range. Trading a smaller multifamily asset for a larger industrial property through a properly structured exchange defers that gain and keeps the capital working.

If you are weighing a sale, a listing valuation helps you see how the assessment history and a potential exchange interact with your likely net proceeds. On the buy side, a buyer consultation is where we model after-tax returns on a target asset before you commit.

Frequently asked questions

Does Florida tax capital gains on commercial property?

Florida has no state personal income tax and no separate state personal capital gains tax, so the state does not add a capital gains layer for individual owners [1]. Federal capital gains tax still applies, with a top long-term rate of 20% plus a possible 3.8% net investment income tax [5].

How much can my commercial assessment rise each year?

For most non-homestead property, the assessed value cannot increase more than 10% over the prior year, except for school district taxes, which are assessed on full just value [2]. The assessment resets to full just value after a change of ownership or control.

Does adding solar raise my property taxes in Florida?

For nonresidential real property, 80% of the just value attributable to a qualifying renewable energy source device installed on or after January 1, 2018 is excluded from the assessment under Florida Statute 196.182 [3]. Eligibility depends on the device meeting the statutory definition.

What are the 1031 exchange deadlines?

You have 45 days from the sale to identify replacement property in writing and 180 days from the sale to close on it, or your tax return due date with extensions if that is earlier [4]. These deadlines are not extendable.

Is this tax advice?

No. This is general information. Tax outcomes depend on your entity, holding period, and the specific parcel, so confirm any figure with a CPA or tax attorney before acting.

If you want to pressure-test how these provisions apply to a specific South Florida asset, that is exactly the kind of modeling I do with clients before they buy or sell.
