File Missouri Taxes & Get Your Tax Refund Faster

Missouri State Sign

Anyone who is considered a resident, a partial-year resident or a nonresident earning money in Missouri must file a MS tax return. Nonresidents must include any income from other states on their returns as well. If a taxpayer dies before he or she is able to file their taxes, that individual's surviving spouse may file for the decedent.

The top income tax rate is 6%, which places it at number 19 on a list of the highest state individual income tax rates. The state's tax revenue per individual is close to $1,000 annually. This is close to the median range for all of the United States.

If Missouri tax returns or tax extensions are not filed by April 15, taxpayers who owe money will be charged a rate of 5% of the amount for each month it remains unpaid. The total charges cannot exceed 25% of the amount due. Payment plans may be set up ahead of time on the Department of Revenue's site but will still accrue interest.
