Things You'll Need
Go to the Electronic Filing page, http://dor.mo.gov/tax/electronic. on the Missouri Department of Revenue website. Click on the link for "Free Online Filing of Federal and State Income Tax Returns through the Free File Alliance."
Compare eligible providers. Important questions when comparing tax-preparation providers: Is the entire fee paid? How long has the organization been in operation? Are there income requirements? Are you active in the military?
Review Intuit. Intuit has been allowing Missouri residents to file state income-tax returns for free since 2004. To meet eligibility, residents must qualify for the Earned Income Tax Credit, have earned $31,000 or less or have served active duty in the military. You must access Intuit and all the
providers through a link on the Missouri Department of Revenue website to receive a rebate.
Consider TaxHawk.com, which allows you to prepare your state return for free if your income is $20,000 or less.
Consider TaxSlayer.com. If your household income is less than $57,000, you are younger than 25, you are eligible for the Earned Income Tax Credit or are active in the military, you can use TaxSlayer.com services for free.
Choose a provider and follow the instructions. You will need your W-2 and previous year's tax return. If you don't know which form to fill out, use the Tax Form Selector on the Missouri Department of Revenue website. Once you've completed the return, you can submit it directly online.
