Average monthly withholding amount (AMWA) We determine the type of remitter you are by adding up all the CPP, El, and income tax you had to send us for your payroll program accounts two calendar years ago. We divide the total by the number of months in that year (maximum 12) that you had to make payments in. For example, if you made two monthly remittances totaling $120,000 in 2018, your AMWA for 2020 would be $60,000 ($120,000 divided by 2), and you would be a Threshold 1 accelerated remitter. If your remitter type changes based on our calculations, we will inform you in writing, usually in December, of when we have to receive your remittances for the following year. Example 1 ABC company's AMWA was $26,000, On October 22, 2021, employer pays employees for work done in October. Since employer pays this remuneration between October 16 and October 31, the CRA would normally have to receive his remittance by what date? Example 2 ABC company's AMWA was $2,500, On October 22, 2021, employer pays employees for work done in October, the CRA would normally have to receive his remittance by what date
