Read this information first - We encourage you to let us figure your penalties and send you a bill instead of completing this form
yourself. You must complete this form if you are using the annualized income installment method for late-payment penalty for underpayment
of estimated tax in Step 6. You do not owe the late-payment penalty for underpayment of estimated tax if you made timely estimated
installment payments equaling at least 90 percent of this year’s tax liability or 100 percent of the prior year’s tax liability (provided you reported
a liability in the prior year and it was not a short taxable year). See the Specific Instructions for more information. The late-payment penalty for
underpayment of estimated tax is based on the tax shown due on your original return. Do not use the tax shown on an amended return filed
after the extended due date of the return to compute your required installments in Step 2.
