Verified against enacted text: September 2, 2026. Primary source.
What a merchant must do
Minnesota's law covers state agencies only, not private merchants. Under new Minn. Stat. 16A.402, an agency, or a party transacting on its behalf, may round cash payments to the nearest five cents. An agency that engages in cash transactions must establish a written rounding policy and post it at each location where cash transactions occur. Effective May 28, 2026, the day following final enactment (Laws 2026, Chapter 119, HF 4591).
Tax base treatment
Not addressed by the enacted text. The cash-rounding section contains no separate tax-base provision.
Mixed tender treatment
Addressed by exclusion. The section does not apply to any transaction paid by electronic fund transfer, check, gift card, money order, credit card, or other similar instrument or method, so noncash portions are excluded from rounding.
Liability protection
No express safe harbor or immunity clause. Protection is regulatory only and contingent on the agency adopting and posting the required rounding policy.
