2018 Minnesota Estate Tax Calculator
Introduction & Importance
The 2018 Minnesota estate tax calculator is an essential tool for estate planners, executors, and beneficiaries to determine potential tax liabilities on inherited assets. Minnesota is one of the few states that imposes its own estate tax separate from the federal estate tax, with unique thresholds and rates that changed significantly in 2018.
Understanding your potential estate tax burden is crucial for several reasons:
- Proper estate planning can minimize tax liabilities for heirs
- Accurate calculations prevent unexpected financial burdens during probate
- Minnesota’s estate tax laws differ from federal laws, requiring separate calculations
- The 2018 tax year introduced important exemption changes that affect many estates

For complex estates with qualified terminable interest property (QTIP) or generation-skipping transfers, consult with a Minnesota estate tax professional.
Formula & Methodology
Our calculator uses the exact 2018 Minnesota estate tax formula:
Taxable Estate = (Gross Estate – Deductions) – Exemption
The 2018 Minnesota estate tax rates applied progressively:
| Taxable Estate Range | Tax Rate | Base Tax |
|---|---|---|
| Over $0 | 10% | $0 |
| Over $1,000,000 | 12% | $100,000 |
| Over $1,030,000 | 13% | $103,600 |
| Over $1,060,000 | 14% | $107,500 |
| Over $1,120,000 | 15% | $115,400 |
| Over $1,200,000 | 16% | $126,400 |
The calculator applies these progressive rates to determine the total tax liability. For example, an estate with $2,500,000 taxable value would pay:
- 10% on the first $1,000,000 = $100,000
- 12% on the next $30,000 = $3,600
- 13% on the next $30,000 = $3,900
- 14% on the next $60,000 = $8,400
- 15% on the next $80,000 = $12,000
- 16% on the remaining $1,300,000 = $208,000
- Total tax = $335,900
