What Is the Unlimited Marital Deduction?
Let me explain the unlimited marital deduction directly: it's a rule in U.S. federal estate and gift tax law that lets you transfer any amount of assets to your spouse anytime, even after you die, without facing taxes on that transfer.
You can see it as a way to preserve your estate, because these transfers to your surviving spouse avoid estate or gift taxes right away.
But remember, if you're giving to anyone else—like non-spouses or organizations—those are limited by IRS rules, and you might owe gift or estate taxes.
Key Takeaways
- Spouses can transfer unlimited money to each other, including after death, without taxes or penalties.
- Gifts to others face IRS limits, gift taxes, and estate taxes.
- Assets transferred to a surviving spouse get included in their taxable estate later.
- For 2024, you can gift up to $18,000 tax-free per person, and the estate tax exemption is $13.61 million.
Understanding the Unlimited Marital Deduction
On the taxation side, this deduction started in 1982 as an estate tax rule. It wiped out federal estate and gift taxes on transfers between spouses by viewing them as a single economic unit.
You can move unlimited property to your spouse while alive or in your will, and there's no federal tax on that initial transfer.
What happens is an unlimited deduction that pushes the taxes back until the second spouse passes away.
Once the surviving spouse dies, any estate assets above the exclusion amount become taxable.
Congress brought this in to fix how inflation was shoving estates into higher tax brackets, since estate taxes are progressive like income taxes.
For 2024, you can make financial gifts up to $18,000 without gift tax—that's higher than $17,000 in 2023, and it goes to $19,000 in 2025.
Important Thresholds
The IRS estate tax exemption is $13.61 million for 2024, up from $12.92 million in 2023, and it rises to $13.99 million in 2025.
Special Considerations
Any asset you transfer to your surviving spouse can end up in their taxable estate, unless they spend or gift it during their life.
If they remarry, the deduction might let those assets go to the new spouse tax-free. Sometimes, you pay less tax overall with other planning like exemptions or trusts.
Qualified Domestic Trusts
This deduction only applies to U.S. citizen surviving spouses. For non-citizens, you can set up a qualified domestic trust (QDOT) to get the unlimited deduction.
With a QDOT, estate tax is deferred until the trustee—a U.S. citizen or corporation—distributes the principal, and they withhold the tax then.
Income from the principal paid to the surviving spouse gets taxed as their personal income. If they become a U.S. citizen, the remaining principal can be distributed without more tax.
Why Is the Unlimited Marital Deduction Important?
It's key because you can pass any amount of assets to your spouse, before or after death, without estate or gift taxes hitting you right then.
What’s the Purpose of the Unlimited Marital Deduction?
The goal was to stop estate values from climbing into higher tax brackets just because of inflation.
Does the Unlimited Marital Deduction Eliminate Taxes?
No, it doesn't eliminate them—it just defers them. Estate taxes, if they apply, come due when the second spouse dies.
The Bottom Line
In essence, the unlimited marital deduction is your tool for estate planning, letting you transfer assets to your spouse without immediate estate or gift taxes.
It treats you and your spouse as one economic unit, starting in 1982 to ease the burden of inflation pushing estates into higher taxes.
