What Is the Estate Tax Exemption in Minnesota?

Understanding how estate taxes work in Minnesota is crucial if you're planning to protect your assets and provide a smooth transition for your heirs. The Minnesota estate tax is separate from the federal estate tax, with its own exemption threshold and rate structure. This article explores how the Minnesota estate tax exemption works, who needs to file, what the thresholds are, and how families can reduce or plan for estate tax liability.

Minnesota Estate Tax Exemption Threshold

For individuals who pass away in 2020 or later, Minnesota provides a state-level estate tax exemption of $3,000,000. This is known as the exclusion amount, and it functions similarly to the federal exemption by exempting a portion of the estate's value from taxation.

Breakdown by Year of Death:

2020 to Present: $3,000,000 exclusion
2019: $2,700,000 exclusion
2018: $2,400,000 exclusion
2017: $2,100,000 exclusion

This means that if your total estate is valued under $3 million at the time of death, no Minnesota estate tax return is required. However, once your estate surpasses that threshold, a Minnesota estate tax return must be filed, and tax may be owed.

Minnesota Estate Tax Rates

If an estate exceeds the exemption threshold, the taxable amount is subject to graduated tax rates. These rates have been fixed since 2018 and are among the highest state-level estate taxes in the country.

Tax Schedule for Estates (2018 and beyond):

Minnesota Taxable Estate Amount	Tax Rate
Not over $7,100,000	13%
$7.1M - $8.1M	$923,000 + 13.6% of excess over $7.1M
$8.1M - $9.1M	$1,059,000 + 14.4% of excess over $8.1M
$9.1M - $10.1M	$1,203,000 + 15.2% of excess over $9.1M
Over $10.1M	$1,355,000 + 16% of excess over $10.1M

These rates apply only to the value above the exemption, not to the entire estate.

How the Minnesota Taxable Estate Is Calculated

The Minnesota taxable estate is generally aligned with the federal taxable estate, but with several key differences:

Increases to the Estate:

Gifts made within three years before death.
State and foreign death tax deductions added back in if excluded federally.
Qualifying life interests under certain QTIP trusts, if previously elected for state but not federal tax purposes.

Reductions (Subtractions) from the Estate:

The $3 million exclusion amount for decedents dying in 2020 or later.
Additional deductions for:
- Qualified small business property.
- Qualified farm property.

Combined, these deductions may reduce the taxable estate by up to $5 million, but never below zero.

Gift Addbacks: A Key Difference in Minnesota

Minnesota uniquely adds back taxable gifts made within three years of the decedent's death, even if these gifts were not subject to federal estate tax. This rule can significantly increase the size of the Minnesota taxable estate and should be considered in any estate planning strategy.

Gifts are valued using IRS Code section 2512, and their value must be excluded from federal estate figures to qualify for Minnesota addback inclusion. This provision can create a surprise estate tax burden if gifts were made shortly before death.

Federal vs. Minnesota Estate Tax Exemptions

Minnesota's $3 million exemption is far less generous than the federal exemption, which for 2025 is set at $13.99 million. However, estates must still navigate both systems depending on size.

You may owe:

Only Minnesota estate tax, if your estate is valued between $3 million and the federal exemption limit.
Both state and federal estate tax, if your estate exceeds $13.99 million.

It's important to engage in estate planning that factors in both sets of laws, especially for high net worth individuals who could trigger tax liability at both levels.

Estate Tax Filing Requirements in Minnesota

An estate must file a Minnesota estate tax return (Form M706) if:

The gross estate exceeds $3 million, and
The decedent owned property with a Minnesota situs, even if they weren't a Minnesota resident.

This includes:

Real estate in Minnesota.
Tangible personal property located in Minnesota.
Ownership interests in Minnesota-based businesses.

The return must be filed within nine months of the date of death, mirroring the federal filing deadline. Extensions may be requested, but interest begins accruing after the original due date.

How to Minimize Estate Tax Liability in Minnesota

Effective estate planning can help reduce or eliminate Minnesota estate tax liability through legitimate legal strategies. While Minnesota does not allow portability of the exemption between spouses, there are several ways to mitigate the potential tax burden.

1. Use of Trusts

Establishing the right kind of trust can help manage how assets are distributed and reduce taxable value.

Credit Shelter Trusts (also called Bypass Trusts) can preserve the deceased spouse's $3 million exclusion.
Irrevocable Life Insurance Trusts (ILITs) can exclude life insurance proceeds from the taxable estate.
Grantor Retained Annuity Trusts (GRATs) and Charitable Remainder Trusts (CRTs) offer other opportunities to reduce the estate's value.

2. Lifetime Gifting (With Caution)

While gifting assets during life can remove them from the federal estate, Minnesota law requires addbacks for gifts made within three years of death. Still, long-term gifting strategies remain effective for reducing estate value when planned properly and with sufficient time.

Key point: Gifting should ideally begin early to avoid the three-year lookback period under Minn. Stat. § 291.016.

3. Business and Farm Property Deductions

Minnesota offers valuable deductions of up to $2 million for qualified small business property or farm property passed to family members. To qualify:

The property must have been owned for at least three years.
The heir must continue operating the business/farm for at least three years after inheritance.

These deductions are available in addition to the $3 million exclusion, helping reduce the taxable estate significantly for family-run enterprises.

Common Traps in Minnesota Estate Tax Planning

Understanding Minnesota's estate tax nuances is vital to avoid missteps that could result in unintended tax liability:

Assuming federal exemption applies to state tax - It doesn't. Many families are shocked to discover they owe Minnesota tax on estates far below the federal threshold.
Overlooking property with Minnesota situs - Nonresidents with Minnesota-based real estate or tangible assets must still file.
Failing to file on time - Minnesota does not forgive interest if you miss the nine-month deadline, even if you qualify for a filing extension.
Underestimating the value of taxable gifts - These addbacks can tip an estate into the taxable range.

Work with a knowledgeable estate planning attorney to navigate these complex rules and preserve more of your estate for your beneficiaries.

Why Estate Planning in Minnesota Demands Proactive Action

Because the Minnesota estate tax exemption is significantly lower than the federal threshold, many individuals and families fall into a taxable range without realizing it. This is especially true for:

Business owners
Landowners and farmers
Individuals with life insurance or retirement assets
Families who have received prior generations' wealth

A carefully drafted estate plan, often including trusts, asset transfers, and gifting strategies, can minimize or eliminate state estate taxes. But timing is critical - many of these strategies only work when implemented well in advance of death.
