A Complete 2026 Guide to Estate Tax Filings, Deadlines, and Common Mistakes
When a loved one passes away, taxes are usually the last thing on your mind. Between grief, funeral arrangements, and supporting your family, dealing with the IRS can feel overwhelming.
But ignoring estate tax obligations can lead to penalties, interest, and even personal liability for the person managing the estate.
So, does a deceased estate need to file a tax return in Florida?
In most cases, yes, but it’s not just one return. Depending on the situation, up to three federal tax filings may be required.
This article breaks down exactly what you need to know using clear explanations.

Quick Answer
Yes, a deceased estate in Florida often needs to file tax returns.
There are typically three possible federal filings:
- Final personal income tax return (Form 1040)
- Estate income tax return (Form 1041)
- Federal estate tax return (Form 706)
Not every estate needs all three, but most require at least one.
The 3 Tax Returns You Need to Know
One of the most important concepts is this:
The IRS treats the deceased person and their estate as two separate taxpayers.
Here’s how that works.
-
Final Personal Income Tax Return (Form 1040)
This is the last individual tax return for the person who passed away.
What It Covers
- Income earned from January 1 through the date of death
Who Files It
- The personal representative (executor)
Deadline
- Typically April 15 of the following year
This is required in most situations where the decedent had income.
-
Estate Income Tax Return (Form 1041)
After death, the estate itself may generate income.
When It’s Required
If the estate earns more than $600 in gross income, you must file Form 1041.
Common Sources of Estate Income
- Interest from bank accounts
- Dividends from investments
- Rental income
- Capital gains from asset sales
Key Insight
This is one of the most commonly missed filings and can trigger penalties if overlooked.
-
Federal Estate Tax Return (Form 706)
This is the return most people associate with the “death tax.”
When It’s Required
Only if the estate exceeds the federal exemption:
- 2026 exemption: $15 million per person
Important Reality
- Over 99% of estates will NOT owe federal estate tax
- But in some cases, filing is still strategically important (explained below)
Florida vs. Federal Estate Taxes
Here’s the key distinction:
Florida Estate Taxes
- No state estate tax
- No inheritance tax
Florida eliminated its estate tax for deaths after January 1, 2005.
Federal Estate Taxes
- Apply only to very large estates
- Governed by federal law
- Require careful planning in high-net-worth situations
A Critical Strategy: Portability (Often Overlooked)
Even if no estate tax is owed, filing Form 706 may still be essential.
What Is Portability?
Portability allows a surviving spouse to use the unused estate tax exemption of the deceased spouse.
Example (2026)
- Individual exemption: $15 million
- Married couple: up to $30 million combined
The Catch
Portability is NOT automatic.
To preserve it:
- You must file Form 706
- Even if no tax is owed
Why This Matters
Failing to file could cost your family millions in future tax savings.
Step-by-Step: What to Do After Someone Passes Away
If you’re the personal representative, here’s a practical roadmap:
Step 1: Gather Financial Documents
- Prior tax returns
- Bank and brokerage statements
- Property records
- Income records
Step 2: Determine Required Filings
Ask:
- Is a final 1040 required?
- Did the estate earn over $600 (triggering 1041)?
- Should Form 706 be filed for portability or tax planning?
Step 3: Track Deadlines Carefully
- Form 1040 → April 15
- Form 1041 → April 15 (generally)
- Form 706 → 9 months after death
Missing these deadlines can result in penalties and complications.
Why Estate Tax Filing Mistakes Are Risky
Handling taxes incorrectly can lead to:
- IRS penalties and interest
- Delays in estate administration
