Unpaid special assessment interest accrual rate modified, refunds on interest payments required, and technical changes made.

HF 238 modifies the interest rate applied to unpaid special assessments in Minnesota, which are fees for local improvements like roads or sewers. It requires municipalities to refund interest payments made under the previous rate if they were overcharged. The bill directly affects property owners who pay these assessments and may owe interest on unpaid amounts. Key changes include setting a new interest accrual rate and mandating refunds for overpayments, as specified in the amended Minnesota Statutes section 429.061.
