The following diagnostic is generating: e-file: The electronic postmark date is not valid. Property tax refund returns containing form PROPST must be filed on or after March 15. (ref. #39598)

I assume this is related to the M1PR that we are attempting to efile. In other words, we need to wait until 3/15 to file the return as a result?

Minnesota does not accept those returns until March 15th.  Make sure you are using the 2026 property tax statements to calculate.
