Modifies provisions requiring employers to file Missouri income tax returns electronically

HB 1919 changes Missouri's requirement for employers to file wage tax information returns electronically. Starting January 1, 2027, employers with at least 10 employees must submit these returns electronically by January 31 each year, using the same file specifications as required by the Social Security Administration. This applies to employers who withhold wages and would otherwise be required to file similar returns with the IRS. Employers granted an IRS waiver for electronic filing automatically receive the same waiver for Missouri filings.
