What is 84-131?
Schedule K (2025), Mississippi Form 84-131, is the Mississippi Department of Revenue schedule that lists, owner by owner, a pass-through entity election: each partner's or shareholder's name, ownership percentage, Mississippi taxable income (loss), credits and the tax paid by the electing entity.
The form is identified on its face as Form 84-131-25-8-1-000 (Rev. 10/25) for page 1 and Form 84-131-25-8-2-000 (Rev. 10/25) for page 2. It is a Mississippi schedule, separate from any federal schedule with a similar name. At the top you enter the entity's FEIN and mark whether it is a Partnership / LLC / LLP (Federal 1065) or an S Corporation (Federal 1120-S).
Page 1 has room for five owners, each described in four columns: Column A (name, FEIN or SSN, state of residence and a box for composite), Column B (ownership %, to the fourth decimal place), Column C (Mississippi taxable income (loss), credit code and credit amount) and Column D (tax paid by the electing pass-through entity). Lines 2 through 5 total those columns. Page 2 is a supplemental page for additional owners; its subtotal carries to page 1, line 3.
When the entity reports composite income, the form tells you to enter the total composite income (loss) from line 4a on Form 84-122, page 2, line 29.
Who needs to file 84-131?
The entity that has made the Mississippi pass-through entity election completes Schedule K (Form 84-131) to list its owners. The form is built for two types of entity, each marked at the top of page 1:
- a partnership, LLC or LLP that files federal Form 1065;
- an S corporation that files federal Form 1120-S.
The schedule is not completed by the individual partner or shareholder as a personal return. Each owner appears as a row, identified by name, FEIN or SSN and state of residence. An owner who is part of the composite computation is marked with the Composite check box in Column A.
Entities with more than five owners continue on the supplemental page (page 2), which has the same five-row layout. The form itself does not describe who may sign or file on the entity's behalf, and it does not state the conditions of the election, so check with the Mississippi Department of Revenue for eligibility questions.
When to file 84-131
Schedule K (Form 84-131) is marked as a 2025 form, so it covers the 2025 pass-through entity election. No due date is printed on the schedule itself. Complete it when you prepare the entity's election information for that year, since its totals feed other Mississippi forms: composite income from line 4a goes to Form 84-122, page 2, line 29, and the page 2 subtotal goes to page 1, line 3.
For the filing deadline that applies to the election, check with the Mississippi Department of Revenue, which publishes its forms at https://www.dor.ms.gov/forms-resources/form-search.

Common mistakes to avoid
- Leaving the FEIN at the top of the page blank; it is requested on each page, including the supplemental page.
- Not marking whether the entity is a Partnership / LLC / LLP (Federal 1065) or an S Corporation (Federal 1120-S).
- Entering the ownership percentage in Column B without carrying it to the fourth decimal place, as the column heading requires.
- Forgetting to check the Composite box for an owner who is part of the composite computation.
- Entering the page 2 subtotal anywhere other than Form 84-131, page 1, line 3.
- Reporting composite income without carrying the line 4a total to Form 84-122, page 2, line 29.
- Putting the owner's tax paid by the electing entity in Column C instead of Column D, so line 5 does not equal column D, line 2 plus line 3.
