What is Oklahoma's capital gains deduction?

Oklahoma allows a 100% deduction for net capital gains from the sale of Oklahoma property held for more than 5 years. This means that if you sell an Oklahoma rental property or business that you have owned for over 5 years, the entire gain may be excluded from Oklahoma taxable income. This is one of the most generous state capital gains provisions in the country and is a major planning consideration for long-term OK investors.

How is oil and gas royalty income taxed in Oklahoma?

Oil and gas royalty income is taxable on both federal and OK returns. Federal percentage depletion (15% for oil and gas) reduces taxable royalty income.

OK royalty owners should verify that the gross production tax is being properly reflected in their royalty statements.
