Every person so notified by the appropriate TTB officer shall file a return for the calendar month or semimonthly period in which the notice is received and for each calendar month or semimonthly period thereafter until the person has filed a final return in accordance with § 53.152 or is required to file returns on the basis of a different return period pursuant to notification as provided in paragraph (b)(2) of this section.

(2) Change of requirement. The appropriate TTB officer may require the taxpayer, by notice in writing, to file a quarterly or monthly return, if the taxpayer has been filing returns for a semimonthly period, or may require the taxpayer to file a quarterly or semimonthly return, if the taxpayer has been filing monthly returns.

(3) Return for period change takes effect.
