Missouri Department of RevenueFederal Income Tax Deduction
The State of Missouri allows a deduction on your individual income tax return for the amount of federal tax you paid. The deduction is for the amount actually paid as indicated on your Federal Form and NOT the amount withheld by your employer that is listed on your Form W-2.
Do not use the amount of federal tax withheld from your Form W-2. You should use the Line references provided in the instructions to figure your federal income tax deduction. If you received an earned income credit, it must be subtracted from your federal tax to calculate your Missouri deduction.

Amounts Included in Other Federal Tax
Section 143.171, RSMo includes provisions for a deduction of the federal tax you pay other than the tax paid on ordinary income. If you have “other federal tax”, you must file a Form MO-1040 or file your return electronically. (You cannot claim a deduction for “other federal tax” on Missouri short forms.) If you did not file a Federal Form 1040, you do not qualify for the deduction for “other federal tax.”
Other Federal Tax
Enter the total amount of Lines 45, 47, 58, and any recapture taxes included on Line 60 from Federal Form 1040. Enter the amount of alternative minimum tax included on Line 28 of Federal Form 1040A. For amended returns enter the other taxes reported on Line 9 of Federal Form 1040X except: do not include self-employment tax, FICA tax, or railroad retirement tax on this line.
