Based on the search results, ACWB stands for "Advanced Canada workers benefit". It is a refundable tax credit to help individuals and families who are working and earning a low income. The ACWB payments are sent automatically, and recipients dont need to apply to receive them. Starting in July 2023, ACWB recipients will receive half of their 2022 CWB allotment in quarterly instalments in July, October, and January, and the remaining amount will be reconciled once they file their 2023 tax return next spring.
