10-43-30. Estimated tax payments--Time for filing annual return--Interest and penalty on underpayment and delinquency. Any person required to file and pay tax pursuant to this chapter and whose tax liability in the previous year exceeded ten thousand dollars shall file with the Department of Revenue and Regulation a quarterly estimate of the amount of tax due for the current year and make payment of the estimated amount. If the tax year of the person ends on December thirty-first, the estimated amount shall be paid on or before the fifteenth day of January, April, July, and October of each year. If the tax year of the person ends on a date other than December thirty-first, the estimated amount shall be made on or before the fifteenth day of the month following the end of the quarter for which the estimate is due. In determining the amount of each quarterly payment, the taxpayer shall estimate the taxpayer's total tax liability for the entire tax year and make payment of one-fourth of the estimate.
Each taxpayer shall file the final return for the tax year within fifteen days after the taxpayer's federal income tax return is due. For taxpayers required to make quarterly estimated payments, if the total quarterly estimated payments do not equal ninety percent of the total tax due, then interest, but not penalty, accrues at the rate provided in § 10-59-6 and is applied to the amount by which one-fourth of ninety percent of the total tax due exceeds the amount of any quarterly estimate filed or required to be filed from the time the estimate was due until finally paid. Neither interest nor penalty may be imposed on quarterly estimates if each estimate equaled an amount which would have been required on that date had the estimated tax been based upon the tax shown on the previous year's return.
Any tax due but not paid on the due date is delinquent and bears penalty and interest as provided in § 10-59-6.
