RC210 |
Prior Year |
*CWB (Canada Workers Benefit) advance payments was replaced in July 2023 with automatic advance payments based on the prior year's tax return. It is also referred to ACWB (Advanced Canada Workers Benefit). It was formerly called WITB (Working Income Tax Benefit) which applied to tax years prior to 2019.
Benefits payment schedule:
- CCB payments are made by direct deposit or cheque around the 20th of each month.
- OAS & GIS benefit payments are made monthly typically the last week of each month. Both are tied to CPI (consumer price index) meaning the amount is reviewed each quarter. Payments increase if inflation is up. If there is no change in CPI or it drops, then there is no indexing.
- CPP benefit payments are made monthly typically around the third to last business day of the month. They are tied to the CPI index. Unlike OAS & GIS, the rate increases are calculated one a year and applied in January. Payments increase if inflation is up. If there is no change in CPI or it drops, then there is no indexing.
- GST credits are made quarterly on the 5th of July, October, January and April.
- CCR (Climate carbon rebate) payments are made quarterly on the 15th of April, July, October and January if you file you T1 on or before March 15th.
- Automatic, advance CWB refundable tax credit payments are made on July 28th, and the 12th of October and January based on the prior year and automatically provide advance payments equal to 50% of the CWB credit. To receive CWB you need to file your T1. Advances that exceed the the entitlement for the current year will not have to be repaid.
