How It Works
Trusts pay federal income tax on a compressed schedule that punishes retained income hard. Where an individual climbs gradually toward the top rate, a trust hits the 37% marginal bracket at just $16,000 of taxable income for the 2026 tax year. Grasping how quickly that ceiling arrives is the heart of sound trust planning and the difference between an expected bill and a painful one.
Using the 2026 federal rates for non-grantor trusts and estates, the calculator works through a progressive bracket structure in which successive slices of taxable income face rising marginal rates. The lowest rate applies to the first segment of income, the next rate to the segment above it, and so on until every dollar of taxable income has been accounted for, following the same layered approach laid out in IRS Publication 505.
The scope here is federal income tax only, so state and local taxes, which differ considerably from place to place, fall outside the estimate. Feed the calculator the trust's taxable income after all allowable deductions rather than its gross income. Distributable net income (DNI) and taxable income are not interchangeable, and conflating the two is one of the surest paths to a miscalculation.
Example: Calculating Tax for a Simple Trust with $20,000 Taxable Income
- 1 Input the trust's taxable income: $20,000.
- 2 The calculator applies the 2026 trust tax brackets: $0 - $3,300 taxed at 10%, $3,301 - $11,700 taxed at 24%, and $11,701 - $16,000 taxed at 35%, with the remaining $4,000 ($20,000 - $16,000) taxed at 37%.
- 3 The calculated federal income tax liability for the trust is $5,331.00 ($330 + $2,016 + $1,505 + $1,480).
- 4 This example demonstrates how quickly a trust's income can be subject to the highest tax rates, reaching the 37% bracket with only $20,000 of taxable income. For comparison, an individual taxpayer would need over $640,000 in income to reach the 37% bracket in 2026.
