When someone passes away in Florida, settling the estate often means filing tax returns with tight deadlines. Missing a single form can trigger penalties or delay the final distribution to heirs. A clear estate settlement tax filing requirements checklist keeps you organized and helps you avoid expensive missteps.

What tax returns does a Florida estate typically need to file?

Florida does not impose its own estate tax or state income tax, so most of the filing requirements come from the federal side. Even so, the list can catch personal representatives off guard. The three most common returns are:

  • Final individual income tax return (Form 1040) – for the deceased person’s income from January 1 through the date of death.
  • Estate income tax return (Form 1041) – filed if the estate earns more than $600 in gross income during the tax year, such as rental income, dividends, or interest from investments.
  • Federal estate tax return (Form 706) – required only if the gross estate exceeds the federal exemption amount ($13.61 million in 2024, $13.99 million in 2025). Florida no longer has a separate state estate tax return for deaths after 2004.

There may also be gift tax returns (Form 709) if the deceased made large gifts before death, and generation-skipping transfer tax returns in rare situations. Using a free estate tax documentation checklist can help you confirm which forms actually apply to your case and mark them off as you go.

When are the deadlines for filing estate tax forms?

Timing is everything. Here are the key due dates to put on your calendar:

  • Final Form 1040 – due by April 15 of the year following the individual’s death. You can request a six-month extension on Form 4868.
  • Form 1041 for estate income – due the 15th day of the 4th month after the estate’s tax year ends. Most estates choose a calendar year, making the due date April 15. Extensions are available via Form 7004.
  • Form 706 federal estate tax return – due nine months after the date of death, with an automatic six-month extension available through Form 4768.

If you’re feeling overwhelmed by the timeline, a Florida estate settlement tax planning worksheet lets you map out all dates and estimated liabilities before you ever submit a single form.

Do you really need to file Form 706 for a Florida estate?

Most Florida estates never reach the federal filing threshold, so Form 706 is not required. But even when it’s not mandatory, some executors file it anyway to make the portability election. This allows a surviving spouse to inherit the deceased spouse’s unused exemption amount, which can save millions in taxes later. You must file Form 706 within two years of death to make this election (though relief may apply if you miss the window). Always confirm the current exemption amount on the IRS estate tax page before deciding.

What’s often missing from a settlement tax checklist?

Even careful personal representatives overlook a few things. Watch out for these gaps:

  • State-level tangible personal property tax returns – Florida doesn’t have an income tax, but certain settlement documents for heirs still must account for tangible property, which may need a separate inventory filing with the court.
  • 1099 and W-2 tracking – Investment accounts and final paychecks generate income that needs to go on the proper return. Forgetting to collect every form before filing can lead to amended returns.
  • Non-tax compliance filings – Recording a Notice of Trust or filing a Florida Department of Revenue affidavit for no tax due (Form DR-312) is not a tax return, but missing it can hold up closing the estate.

When you move from broad planning to actually filling out the forms, the step-by-step instructions for preparing estate tax documents can walk you through exactly what to attach and how to sign each return.

How to build a simple, effective filing checklist

Instead of juggling sticky notes and emails, create a short checklist you can reuse for any Florida estate:

  1. Identify all income sources for the deceased (bank accounts, brokerage, rental properties).
  2. Decide whether the estate needs a Form 1041 based on post-death income.
  3. Verify the gross estate value against the current federal exemption to see if Form 706 is needed or if you simply want portability.
  4. Put all due dates in a shared calendar, and set reminders two weeks ahead.
  5. Order official transcripts from the IRS for the year of death to catch any unreported income later.
  6. Keep signed copies of every filed return in a permanent estate file.

A printable checklist, like the one available here, makes it easy to mark off each step and share progress with co-trustees or family members.

Start with the final individual return, then move to the estate income return, and only tackle the federal estate tax return if the numbers require it. Double-check the math and attach all required schedules to avoid processing delays. If you’re ever unsure, a quick call to a CPA who handles Florida estates can prevent a small oversight from turning into a large IRS notice.
