Plastic Packaging Tax Tra
Track packaging weights, recycled content and UK PPT quarterly liability
UK businesses handling plastic packaging must track weights, recycled content and chargeable tonnage every quarter for Plastic Packaging Tax — work most teams do in fragile, error-prone spreadsheets. This module gets PPT out of spreadsheets: define packaging components with unit weight and recycled-content percentage, log manufactured and imported quantities per period, and the engine computes each quarter's plastic, taxable and exempt tonnage and the resulting liability using your configurable rate. The recycled-content exemption and de-minimis relief apply automatically, and a quarterly worksheet rolls everything up ready for the return. It is a data-preparation tool only — it does not file with HMRC, so submission stays the registered business's responsibility.
Key Features
Packaging Component Master
ppt.component records each packaging item's unit_weight_g and recycled_content_pct. A stored is_exempt is computed automatically: components meeting the company recycled-content threshold (default 30%) or flagged non-plastic become exempt, so the chargeable rules apply themselves.
Tonnage-Computing Movements
Each ppt.movement logs a manufactured or imported quantity against a component within the worksheet period. _compute_tonnes converts units to plastic_tonnes, taxable_tonnes and exempt_tonnes via the component's weight helpers, with a constraint keeping dates inside the quarter.
Quarterly Liability Worksheet
ppt.worksheet derives date_start and date_end from year and quarter, aggregates all movements and applies the company's rate per tonne. _compute_totals produces total plastic, taxable and exempt tonnes plus the PPT liability (taxable tonnes x rate) ready for the return figures.
De-Minimis Relief Flag
The worksheet annualises the quarter's plastic tonnage (x4) and sets below_deminimis when it falls under the company's annual de-minimis threshold (default 10t), surfacing whether the business is below the PPT registration tonnage for that period.
Controlled Worksheet Lifecycle
Worksheets move draft to confirmed to 'Submitted to HMRC' via action_confirm (which blocks empty worksheets) and action_mark_submitted, with chatter logging taxable tonnage and liability. Submitted worksheets cannot be reset, and a constraint prevents duplicate year/quarter periods per company.
Configurable Company Settings
res.company holds ppt_rate_per_tonne (defaulting to the HMRC 223.69 rate), ppt_recycled_threshold and ppt_deminimis_tonnes, validated to sensible ranges, so you update the rate each tax year in one place and every worksheet recomputes.
Bulk Period Generator
The Generate Worksheets wizard (ppt.period.generate) creates Q1-Q4 worksheets for a chosen year in one step, skipping any that already exist, so a year's PPT reporting structure is set up in seconds.
Worksheet Tool, You File
This is a transparent data-preparation and worksheet tool: every taxable, exempt and liability figure is traceable back to its components and movements. It does not file with HMRC — Mark Submitted is an internal status flag and the actual return remains the registered business's responsibility.

Why Choose This Module
Get UK Plastic Packaging Tax (PPT) data out of spreadsheets. Define your plastic packaging components with weight and recycled-content percentage, record manufactured or imported quantities per period, and the module computes each quarter's chargeable tonnage and PPT liability using the configurable rate. A quarterly worksheet rolls up taxable vs exempt weight ready for the HMRC return — you keep control of the actual submission.
