Land Sale in Texas but reside in Oklahoma

[JOSADA1]

I reside in Oklahoma, I recently sold land in Texas. Do I need to pay Oklahoma Income tax on the profit from this sale?

If Yes, what is the tax rate on the profits?

I am a disabled veteran is there any wavier for paying taxes on Capital Gains for Federal Tax or Oklahoma Tax on property sales out of state?

No, there is not an income exclusion for the sale of property at a gain on either on a federal or Oklahoma tax return if you are a disabled veteran.
