The Minnesota rebate checks known as "Walz checks" in 2023 were part of a $3 billion tax relief bill signed by Governor Tim Walz. Here is a summary of the key details about their arrival:

• Direct deposit payments started going out in mid-August 2023, around the week of August 16. These payments appeared in bank accounts labeled “State of Minnesota 2021 Tax Rebate Program.”
• Paper checks were mailed starting a few weeks later, with all checks expected to be delivered by the end of September 2023.
• Checks were sent to individuals who made up to $75,000 in gross adjusted income in 2021 or married couples making up to $150,000, with payments up to $1,300 per family including dependents.
• If a check was not received or was uncashed, some were reissued later, with about 150,000 checks remailed after expiring.
• Recipients were cautioned that these checks are valid for 60 days after the issue date.

In short, the 2023 Walz checks arrived starting mid-August for direct deposit and by the end of September for mailed checks. Late reissued checks were sent out into early 2024 for those who missed the initial mailing.
