5. In Part II, enter your current year tax after credits on line 1. Then calculate 90% of this amount for line 2.
6. On line 3, enter the withholding taxes you've paid and subtract this amount from line 1 on line 4. If this amount is less than $500 (or less than $250 for married/RDP filing separately), stop here as you do not owe a penalty.
