Hi, thank you for using Intuit ProFile Community
Three CRA numbers are required to file slips:
1)The transmitter number which ProFile enters in every XML
2)The account number which is the business number, and
3)The WAC matching the account number used
The account number and matching WAC are used to log into the CRA XML transfer server. Firms often use their account number and WAC to log into the CRA server to avoid the need to get a WAC for all there clients account numbers.
So if you want to use your account number you must get a web access code for that account number from CRA.
Hope this helps
