Exemption from tax deduction for senior residents prevents withholding when a prescribed declaration is furnished. An amendment provides that no tax shall be deducted from payments under the listed withholding provisions in the case of a resident individual aged sixty five years or older who is entitled to the specified deduction and furnishes a prescribed duplicate declaration that tax on his estimated total income for the previous year will be nil; the amendment also inserts cross references to this new sub section into the existing subsection governing certificate and exemption procedures.
