Hi @sherrie2 - great question!
Based on the facts you presented you would have a long-term capital gain on the land in the amount of $17,000.
This will be taxable on your Federal income tax return at either 0%, 15% or 20% depending on the total amount of your income for the year (including the $17,000 capital gain).
Florida does not have a state income tax.
Oklahoma does have a state income tax, but there is a capital gains subtraction available for the sale of real property located in Oklahoma that has been owned for over five years. Oklahoma generally requires you to file a state tax return if you have gross income from Oklahoma sources in excess of $1,000. So you would need to file an Oklahoma tax return for the year of sale, but it sounds like you might qualify for the capital gains subtraction, so you wouldn't owe any tax - you would just have to file to report the sale to Oklahoma. The subtraction can be claimed on Form 561-NR for a nonresident of Oklahoma.
I hope this information was helpful!
