The 2025 Tax Sunset: What It Means for Tampa Bay Retirees

If you have spent the last eight years working with a financial plan that assumed your current tax brackets would remain the same, now is the time to pause and reconsider. The Tax Cuts and Jobs Act (TCJA) of 2017 brought with it a series of substantial changes to the federal tax code — lower rates, wider brackets, higher standard deductions — but almost all of those provisions were written with sunset dates. Most of them expire on December 31, 2025. That is not a technicality. For someone living in the Tampa Bay area with significant retirement savings, understanding what the expiration of the TCJA means is one of the most important planning conversations you can have in the next few weeks.

What Changed in 2017? To understand what you are facing, it helps to remember what happened eight years ago. The TCJA lowered the federal income tax brackets across almost every income level. The standard deduction nearly doubled. The corporate tax rate fell to 21% (though that is less relevant to individual retirees, corporate tax treatment does affect pass-through entities and certain investment structures). These changes were presented as permanent, but they were actually temporary — they were scheduled to expire at the end of 2025, allowing Congress to use a procedural tool called reconciliation to pass them with a simple majority rather than a supermajority. Now that 2025 has arrived, that temporary window is closing.

What Happens on January 1, 2026? Unless Congress passes new legislation between now and the end of the year, tax brackets will revert to 2017 levels, adjusted only for inflation. The standard deduction will be lower. Top marginal rates will increase. For someone in the highest bracket, that means moving from a current 37% rate (on income above roughly $578,000) back to a 39.6% rate. For those in the middle and upper-middle brackets, increases of one to three percentage points are typical. This is not theoretical — it is a scheduled change that will affect your 2026 tax return and every year after unless Congress acts.

Why This Matters for Your Retirement Plan If your current retirement income plan assumes you will remain in your current tax bracket, you may be facing a scenario where your tax obligations increase even if your income stays the same. For retirees living in Florida — which has no state income tax — your federal rate is your entire income tax burden. In a state with income tax, you would have both a state and federal increase. But here in Florida, the federal increase is the whole story, and it is substantial.

The impact depends largely on your income level and the source of your retirement income. Someone with $60,000 in annual retirement income will see a modest increase. Someone drawing $150,000 per year from retirement accounts and investment income will see a much more meaningful difference — potentially $3,000 to $5,000 or more per year in additional federal taxes. Over a 20-year retirement, that is money that could have stayed in your portfolio or your checking account.

This Is Your Planning Window The period between now and the end of 2025 is what we call a planning window. It is a time-limited opportunity to make decisions that might not be available to you after January 1, 2026. The most commonly discussed of these is the Roth conversion. If your income is high enough to be subject to higher rates after January 1, you may want to consider converting some or all of your traditional IRA or 401(k) balance to a Roth IRA during 2025, when your marginal rate may be lower. You will owe taxes on the conversion immediately, but you are essentially pre-paying those taxes at a lower rate. After that, the money grows tax-free and comes out tax-free in retirement. For Tampa Bay families with significant IRAs or 401(k)s, this can be a powerful strategy — but only if you execute it before the rates go up.

Another consideration is charitable giving. If you plan to make charitable contributions, making them in 2025 rather than 2026 means the tax benefit is taken at a lower rate. For high-income earners, this can affect whether it makes sense to bunch multiple years of giving into a single year, or to use a Donor Advised Fund strategy.

Tax-loss harvesting opportunities are often available in the final weeks of the year, and with market volatility a consistent feature of our current environment, this is worth reviewing with your advisor.

The Uncertainty Factor There is, of course, uncertainty about what Congress will do. Some provisions may be extended. Others may be modified. The entire package may be allowed to expire. Historically, Congress has often extended tax provisions at the last minute, sometimes with modifications. But betting your retirement plan on the assumption that Congress will act is not prudent planning.

The responsible approach is to plan for the tax increases as scheduled and position yourself to take advantage of this window while it remains open. If Congress extends the provisions, you will not have harmed yourself — you will simply have been prepared for something that did not happen. If they do not extend them, you will be grateful you acted when you had the chance.

What You Should Do Now If you are a Tampa Bay resident with more than $500,000 in retirement savings, or if you have significant income from multiple sources, this conversation should be at the top of your list. Sit down with your advisor — ideally a fiduciary who understands both tax planning and retirement income — and run the numbers on your specific situation. Look at your projected income for 2026 and beyond. Model what your taxes would look like under current brackets versus the scheduled increases. Evaluate whether a Roth conversion, charitable giving strategy, or other tax-optimization technique makes sense for you. Do this before December 31. After that, the window closes and the opportunity passes.
