FISCAL ANALYSIS
ASSUMPTION
Section 143.341- Taxation of Estates & Trusts
Officials from the Department of Revenue (DOR) note this proposal would change how 
resident estates and trusts are taxed.  Currently a resident estate or trust is one in which the estate 
or trust was created at the time of the owner’s death, and they were a Missouri resident at their 
death.  The estate or trust is required to file fiduciary tax on behalf of the estate or trust.  Section 
143.311 requires that resident estates and trusts are taxed the same as individual when paying 
income tax.  Additionally, the statutes specify that the fiduciary tax rate is the same rate as the 
individual income tax rate of 4.7% in tax year 2025.
The Missouri taxable income of a resident estate or trust means its federal taxable income with 
the following adjustments.  The estate or trust can subtract the allowable federal personal 
exemption deduction and can make adjustments to their federal taxable income per Section 
143.341.  This proposal would add another subtraction to Section 143.341.
This will require resident estates and trusts to make a new hypothetical determination in order to 
calculate their Missouri taxable income.  The new hypothetical determination is “the amount 
included in Missouri taxable income of the estate or trust that would not be included as Missouri 
taxable income pursuant to section 143.381, as if said estate or trust were considered a 
nonresident estate or trust as defined in section 143.371.”  Therefore, the Missouri resident trust 
would get a nonresident credit.  
This proposal attempts to allow a resident estate or trust to include in its Missouri taxable income 
only items of income, gain, loss, or deduction from sources within Missouri, and additionally, 
receive a benefit from a credit for income tax paid to another state under section 143.081.  This 
would allow them to limit their income to Missouri-sourced income and get a full credit for the 
income.  This would end up treating them differently than individual filers.  Individual filers 
must report all income regardless of its source and then get a credit for the amount of tax paid to 
another state.  
This proposal would significantly reduce the amount of income that a resident estate or trust 
would pay tax on.  DOR notes that in fiscal year 2024, DOR collected $87,264,064 in fiduciary 
tax.  DOR notes that allowing resident estates and trusts to apportion their income and then also 
claim a credit would provide a significant tax advantage to them.  It would also significantly 
reduce the amount of tax owed to Missouri.  DOR is unable to estimate the actual amount that 
could be reduced by assumes it could be up to the $87,264,064 currently collected. 
This would require DOR to create a new form at a cost of $10,000 for the reporting of this newly 
created calculation and modification of the MO-1041 at a cost of $2,200.  This will also require 
the department’s computer system to be updated at a cost of $7,327. L.R. No. 2611S.01I

Oversight notes the DOR requests a one-time cost for website income-tax changes and updates 
to comply with the proposed language; Oversight does not have any information to the contrary. 
Therefore, Oversight will reflect the above administrative costs to DOR in the fiscal note.  
Officials from the Office of Administration - Budget and Planning (B&P) note this proposal 
would allow Missouri estates and trusts to subtract the Missouri apportioned income from their 
Missouri taxable income, starting with tax year 2026.
B&P notes that this essentially allows estates and trusts to eliminate their Missouri income tax by 
classifying all income as earned outside of Missouri. Missouri collected $87,264,064 in fiduciary 
tax during FY2. Therefore, B&P estimates that this proposal will reduce TSR and GR by up 
$87,264,064 annually beginning FY27 (for tax year 2026 income).
Oversight notes officials from B&P and DOR both assume the proposal will have a direct fiscal 
impact on state revenues. Oversight does not have any information to the contrary. Therefore, 
Oversight will reflect DOR’s and B&P’s estimated impact in the fiscal note.

FISCAL DESCRIPTION
For all tax years beginning on or after January 1, 2026, this act provides an income tax deduction 
for the amount included in Missouri taxable income of a resident estate or trust that would not be 
included as Missouri taxable income if said estate or trust were considered a nonresident estate 
or trust. Such deduction shall only apply to the extent it is not a determinant of the federal 
distributable net income of the estate or trust.
This legislation is not federally mandated, would not duplicate any other program and would not 
require additional capital improvements or rental space.
