Capital gain taxes in Oklahoma

Is a sale of minerals in Oklahoma considered a capital gain for tax purposes?

The short answer is yes.

A sale of royalty or mineral interests in any state is considered a taxable event, and capital gains are paid.

The good news is that if you've held them long enough, your federal rate is a maximum of 15%.

It is possible to delay capital gains if you quality for a 1031 Exchange for other minerals, but this is pretty rare that someone would do this.
