Excess profits tax would reap $7.9 billion for government, budget watchdog says
OTTAWA — The parliamentary budget officer says a hypothetical tax on big corporations’ excess profits last year would generate $7.9 billion for the federal government.
The estimate by budget officer Yves Giroux, in response to a request from the NDP, was calculated by looking at companies whose profits exceeded their 2020 expectations.
The would-be tax rate on those extra earnings — calculated based on the firms’ average five-year profit margin — would be 15 per cent, on top of the current 15 per cent corporate tax on all profits.
NDP MP Peter Julian says the concept comes from a measure during the Second World War, when Canada imposed a 100 per cent tax on profits deemed excessive.
