UK AVEC listed with a headline rate of 25.5%.
Headline 34% gross, 25.5% net after corporation tax at 25%.
Why it mattered: AVEC is a taxable expenditure credit — the 25.5% figure is the net, not the headline. Quoting it as the headline understated the programme and made the comparison with Canada wrong in both directions.
Raised by: Internal research pass
Georgia listed as a flat 30% credit.
20% base plus a 10% uplift for embedding the Georgia promotional logo, with a US$500,000 minimum spend.
Why it mattered: The 30% is not automatic. A production that does not carry the logo gets 20%, which is a materially different comparison.

Listed the 80% qualifying-expenditure cap as applying to all spend.
The 80% cap is lifted for UK VFX costs, which also attract an enhanced 39% rate.
Why it mattered: Missing this understated the UK considerably for any production with meaningful VFX — one of the cases where the UK genuinely beats Canada.
