According to OK.gov:

Any payment of taxes due on April 20th must be remitted electronically in order to be considered timely paid. If the balance due on an electronically filed return is not remitted electronically, penalty and interest will accrue from the original due date.”

Deducting Oklahoma Income Taxes

If you pay Oklahoma income tax, the IRS allows you to claim a deduction on your federal tax return for them. You can claim a state income tax deduction if you itemize deductions on your federal return.

To determine if you should itemize your deductions, add up your calendar-year deductible expenses, including your state income tax expense, to see if the total is greater than the standard deduction amount for your filing status. If you are single you can claim a standard deduction of $12,400. So, if you pay more than $12,400 in state income taxes and other itemized deductions, then consider itemizing your taxes.

Due to the Tax Cuts and Jobs Act, state and local tax deductions, including state income taxes, are limited to $10,000 per year ($5,000 for married filing separately).
