In short: A distilled spirits plant files three operational reports monthly (due the 15th of the following month, rolling forward on weekends and holidays) and, for most filers, a semi-monthly excise tax return (due the 14th day after the period, but moved to the PRECEDING business day on weekends and holidays). The excise deadline moving backward, opposite the usual rule, is the one most often missed.
Monthly operational reports
The production (5110.40), storage (5110.11), and processing (5110.28) reports are due by the 15th day of the month following the reporting period. If the 15th falls on a Saturday, Sunday, or federal holiday, the due date moves to the next business day. This is the ordinary forward-rolling deadline rule.
The excise tax return (and its backward rule)
The excise return (TTB F 5000.24) is filed by frequency set by annual tax liability, semi-monthly by default. It is due no later than the 14th day after the close of the return period, but, unusually, if that day is a weekend or holiday it moves to the immediately PRECEDING business day, not the next one (27 CFR 19.235). The second half of September also has special accelerated due dates. Missing this backward shift is a common, avoidable error.
How filing frequency is set
Combined annual tax liability determines whether you file the excise return semi-monthly (the default), quarterly, or annually. Smaller producers under the relevant thresholds may qualify for less frequent filing, which changes the return periods and therefore the deadlines.
Bond and annual obligations
Beyond the recurring reports and returns, watch bond adequacy as inventory grows, any annual registrations or renewals, and COLA approvals before new labels ship. Treating these as a calendar, not a scramble, is what keeps a DSP out of trouble.
Automating the calendar
Because the operational reports and the excise return are built from the same recorded activity, a system can compute the exact observed due dates for each period, including the preceding-business-day rule and the September special case, and assemble the figures. That turns the calendar from a memory test into a review. See the 5000.24 guide.
