I live in KS but I am fixing to start receiving royalites. Need advice on taxes

I am married and we have one income. I simply want to know how much I should plan to take out for taxes that way I don’t have to pay at the end of the year when I file my taxes. Depletion allowance I think is 15% tax free and tax the 85%? I do my own taxes but I’m wondering if its time to get a CPA.
