Electronic Filing (EFILE) Capabilities

Cantax FormMaster enables you to electronically transmit data from various slips and returns. The 2025 v.1.0 version allows you to file most slips and summaries and transmit them electronically. It also allows you to file returns for registered charities. However, the forms for partnerships have not been approved by the tax authorities. Therefore, do not submit any partnership returns, trust returns, T3 slips, T5013 slips or RL-15 slips prepared with this version to the CRA and Revenu Québec until approved. The software supports EFILE for major slips including T4, T4A, T5, T5013, and many others.

Form Manager And Workflow

The Form Manager is your main working tool when preparing client files. From the Form Manager, you can open forms, create and convert form groups, print forms, print files, print the content of the Form Manager, and send email messages to other tax preparers or to the active client. You can limit the list of forms displayed by selecting the group of forms that you want to view. You can find a form quickly by entering a few characters of the title in the search field. The jump codes allow you to select a form in the list rapidly. Multiple selections allow you to open and print forms, as well as create or modify groups in one single operation.

Data Migration And Previous Year Integration

The software automatically retrieves configurations and data from the previous year’s version to streamline workflows. This feature saves time by carrying forward client information, company profiles, and other settings. You do not need to re-enter data that remains unchanged from the previous year. The migration process ensures continuity across tax seasons and reduces the risk of data entry errors. This is particularly valuable for firms handling large volumes of tax information slips.
