Keep the quarter, not just the answer
Every figure above is free, forever, with no key and no cap. The $60 licence key adds CSV export of each quarter's eight figures — including the £1,928.46 tax line and the £1,340 penalty line — for your records and HMRC evidence, plus a browser alarm 30, 14 and 1 days before the due date the tool just calculated. $60 once · one licence key per person or team seat · UK tax advisers bill £75 to £250 an hour, and a Plastic Packaging Tax registration-and-return review is rarely under two hours.
The 2026-27 rate, already in Charges taxable tonnage at £228.82 per tonne, the rate HMRC uprated to on 1 April 2026, and keeps the 2025-26 rate of £223.69 selectable for corrected earlier periods.
10-tonne registration test Nets exempt tonnage off your rolling 12-month total and says whether you have crossed 10 tonnes and must register within 30 days.
30% recycled-content split Charges only the share of a quarter's tonnage that sits in components below 30% recycled plastic, instead of averaging recycled content across the whole company.
£500 plus £40-a-day clock Adds the fixed £500 penalty and £40 for each day past the deadline, so the cost of finding out late is a number rather than a worry.
Due date from your period end Returns the last working day of the month after your accounting period end, stepping back off Saturdays and Sundays the way HMRC does.
CSV export and deadline alarm With the $60 key, saves each quarter's figures as a CSV row for your records and sets a browser alarm ahead of the due date the tool calculated.
