§1514. Power to extend time to file returns and pay tax
Upon the written request of the taxpayer and for good cause shown, the collector may grant reasonable extensions of time for the filing of returns and payment of tax due under this Sub-title; provided that such extensions of time shall not exceed six months in the case of income taxes, thirty calendar days in the case of sales taxes, and sixty calendar days in the case of any other tax due under this Sub-title. Whenever such an extension is granted, the return or tax for which the extension is granted shall not become delinquent until the expiration of the extension period; but interest will accrue on the tax during the period of the extension, such interest to be computed in all cases from the date the tax would have become delinquent in the absence of an extension.
