Have you considered temporary differences in your income tax calculations for the year? it appears you may have a few of these.

I really don't understand taxes very well. I just multiplied our income by our $21\%$ tax rate. I have no idea what you mean by temporary differences. What would cause those? How the above can possibly violate FASB or GAAP rules, also provide answer following the IRAC method, with GAAP or FASB codifications. Thank YOu
