What is the penalty for underpayment of estimated tax? Actually, under the US tax law (please refer IRC 6654 ) a taxpayer is supposed to estimate current year income and tax thereon. Then, he/she is supposed to pay the tax on the estimated income in four quarterly instalments. The payment of estimated tax liability can be done in two ways. If there is a shortfall in the payment of estimated tax, IRS charges interest for the shortfall. That is called the estimated tax underpayment penalty.
