A survey conducted for H&R Block last December found the vast majority of Canadians don’t claim all the tax credits they’re entitled to. Canadians living in the prairies were the most likely to file for new tax credits introduced last year, with 42 per cent of filers claiming them on their returns. By contrast, only 18 per cent of Quebecers did the same. Across Canada, only one out of four taxpayers claimed the credits on their tax returns. “How can you leave that kind of money on the table?” wondered Cleo Hamel, a senior tax analyst at H&R Block.
