Mandatory preparer number to produce Relevé 31
Why is the preparer number required?
Before you produce your Relevé 31 slips (Quebec’s RL-31 slips) in Plexflow, you must obtain a preparer number from Revenu Québec.
This number officially identifies the person, business, or organization responsible for preparing and transmitting slips over the Internet, including Relevé 31 slips.
This is the first step to complete before you start producing your Relevé 31 slips in Plexflow.
What is a preparer number?
A preparer number is an identifier assigned by Revenu Québec to the person, business, or organization that prepares and transmits slips over the Internet.
This number is used in particular to transmit Relevé 31 slips to Revenu Québec.
Starting with the production of Relevé 31 slips for the December 2026 period, obtaining a preparer number will become a mandatory step to transmit the slips to Revenu Québec.
Who must obtain a preparer number?
Each Plexflow account must obtain a single preparer number provided by Revenu Québec in order to produce its Relevé 31 slips.
This number is required only once per Plexflow account, regardless of:
- whether you are a management company, an owner, or any other type of organization;
- the number of subaccounts associated with your account;
- the number of buildings;
- the number of units.
Before making a new application, we recommend checking whether you already have a preparer number in your Revenu Québec account.
