The Unlimited Marital Deduction and Your Taxes
How the Unlimited Marital Deduction Can Benefit Your Estate
It can pay to tie the knot—at least according to the Internal Revenue Service. The IRS offers an unlimited marital deduction that allows married couples to make unlimited interspousal transfers of property without incurring a tax, either during their lifetimes or after their deaths. The deduction applies to both estate taxes and gift taxes.
Citizenship Counts, Too
All U.S. residents can take this deduction for property transferred to a spouse who is also a U.S. citizen, but the rules change for non-citizen spouses.
The deduction is not allowed if the spouse of the person making the gift is not a U.S. citizen, but the gifting spouse can give them up to $152,000 as of 2018 without incurring gift tax consequences. This amount is indexed for inflation, so it will go up periodically to keep pace with the economy.
Some Other Rules
The unlimited marital deduction is only available until the second spouse dies. If they do not spend or deplete it during their lifetime, the value of the estate may be subject to estate taxes as they pass the property on to their own heirs. If they give the money or property to anyone other than a spouse, they may incur a gift tax.
A surviving spouse can share the unlimited marital deduction with their new spouse, however, if they remarry. They could inherit from the first spouse and gift or leave the property to the second spouse without taxation, but it would be taxed if it were left it to other beneficiaries such as children.
As of 2018, the estate and gift tax combined exemption was $5.6 million. Property passed over this amount to most individuals or entities other than a spouse is subject to either an estate or gift tax. The IRS additionally covers a $15,000 annual gift tax exclusion. The surviving spouse can give away this much per person per year during their lifetime without incurring a gift tax, regardless of the marital deduction.
The Unlimited Marital Deduction and Living Trusts
All this can require some intricate estate planning because certain living trusts can dodge the usual rules.
If a decedent leaves property for the benefit of their surviving non-citizen spouse in a properly drafted "Qualified Domestic Trust, the "QDOT" will qualify for the deduction.
Property passing into other types of trusts created by one spouse for the benefit of the other also qualifies for the unlimited marital deduction. These include a marital deduction trust or a qualified terminable interest property trust, sometimes called a QTIP trust. This is the "A" Trust in an AB trust plan. Inter vivos qualified terminable interest property trusts, sometimes called inter vivos QTIP trusts, also qualify. These are created for the benefit of a spouse during the trust maker's lifetime—the spouse who creates the trust.
Estate Taxes at the State Level
States that collect an estate tax of their own also allow for unlimited marital deductions. In states that allow for a state-only QTIP election through the use of an ABC Trust plan, the "A" trust and the "C" trust are QTIP trusts that qualify for the state unlimited marital deduction.
