Hi - I am a contractor with highly variable income (150K - 400K annual) , I pay my estimated taxes @30% rateon time based on the income I receive each quarter. My husband's company did not withhold sufficient taxes for his portion of the our married filing jointly income, however, according to form 2210, we paid over the annualized minimum requirements. I got a bit lost in all the 2210 mess, but how to I prevent future year underpayment penalties when my income is so variable and my husband can just check a box on his work forms so has no other control? What detailed forms in Turbo Tax do I need to go through to understand if I should be asking for a waiver of the penalty?
thank you.
