Information Regarding Itemized Deductions
Federal itemized deductions must be adjusted by adding back state and local sales or income taxes to arrive at Oklahoma itemized deductions. Beginning with Tax Year 2018, Oklahoma itemized deductions will be capped at $17,000, excluding charitable contributions and medical expenses which are not subject to the $17,000 cap. If you claimed itemized deductions on your Federal return, you must claim itemized deductions on your Oklahoma return. This is true even if the Oklahoma itemized deductions are less than the Oklahoma standard deduction.

In the case of resident individuals having income from sources both within and without the State of Oklahoma, the standard or itemized deductions and personal exemptions will be reduced to an amount which is the same portion of the total of Oklahoma AGI to Federal AGI.
