Minnesota Pass-Through Entity Tax (PTET)

Why PTET matters in this state

Minnesota enacted its PTE tax election under Minn. Stat. Chapter 289A in the 2021 special session. The state's top individual rate is 9.85% (Minn. Stat. §290.06 top bracket), and the PTE election applies that top rate flat at the entity level — meaning the federal-deduction arbitrage against the IRC §164(b)(6) SALT cap is materially larger per dollar of allocated income than in flat-rate states like Illinois or Michigan. Typical beneficiaries are Twin Cities professional-services partners (law, consulting, medical groups), S-corp owners with material Minnesota-sourced K-1 income, and multi-state operators whose Minnesota allocation pushes them into the top state bracket personally. The regime was originally enacted with a 2021–2025 effective window; the 2025 legislative extension (HF 3127 / SF 3405, April 2025) carried it forward, but the operative 2026 status — including any rate or scope modifications — should be re-verified against revenue.state.mn.us before electing. The 9.85%-flat-at-entity design is the structural feature that makes Minnesota one of the more economically meaningful PTET regimes in the country.

Election mechanics

The election is made by the due date or extended due date of the entity's income tax return. Minnesota uniquely permits the election to be made on an amended return filed on or before the extended due date — a small but meaningful flexibility versus Massachusetts (which prohibits amended-return elections). Once made, the election cannot be revoked after the original due date. The election is filed via Schedule PTE alongside Form M3 (partnership return) or Form M8 (S corp return). Eligible entities are S-corps, partnerships, and LLCs taxed as either. The unusual eligibility constraint: owners holding more than 50% of the qualifying-owner portion of the entity must consent — a group-control requirement most peer states do not impose.

Owner credit walkthrough

The owner credit is refundable. The manifest does not pin precise form-line-item or allocation citations for this session — consult Schedule PTE instructions for the credit-claim mechanic on owner-side returns (Form M1 for residents, Form M1NR for nonresidents). Multi-owner allocation is pro rata by distributive share against the entity-level tax. Because the credit is refundable, owners whose Minnesota liability is depressed in a given year (NOLs, other credits absorbing tax) still recover the full federal-deduction arbitrage benefit through refund, rather than losing it to a non-refundable absorption ceiling as in Hawaii or California.

2026 changes

HF 3127 / SF 3405 (April 2025) extended the PTE tax regime past its original 2021–2025 sunset — verify the 2026 operative status against revenue.state.mn.us before electing, because the extension's text should be re-confirmed for any rate or scope modifications.

Composite-return interaction

Minnesota PTE stacks with composite/nonresident filing rather than displacing it. The manifest does not pin the precise interaction text for this session; for partnerships with material nonresident-owner mix, consult a preparer on the Form M3-A composite-return interaction with PTE-paid amounts.

§199A QBI interaction

Minnesota PTE reduces federal flow-through ordinary income per Notice 2020-75 by 9.85% of allocated income, materially trimming the §199A QBI base before the federal 20% deduction. Combined with the top-bracket flat-rate trap above, the QBI offset arithmetic for owners in lower personal brackets is more complex than in peer states — preparer-modeled, not back-of-envelope.
