🍁 Canada – Payroll CRA Auto-Update Connector
Automatically fetch and admin-approve CRA payroll tax changes in Odoo
CPP / CPP2 EI Premiums Federal Tax Brackets Provincial Tax BPA
What it does
This module connects your Odoo payroll to the MapleHorn CRA payroll tax feed — machine-readable JSON feed that publishes the latest Canadian federal and provincial payroll tax parameters (CPP, EI, federal brackets, BPA, and more) derived from official CRA publications.
Once installed, your Odoo instance will automatically check for new tax data every day and notify your payroll manager when an update is detected. No more manually editing tax brackets every January or July.
How it works — 3 easy steps
A daily cron job fetches the CRA feed, verifies the SHA-256 checksum, and creates a draft CRA Tax Update record if new data is detected.
Your payroll manager receives an email notification and an Odoo activity. Open the record to see a side-by-side comparison of old vs new values for every tax parameter — CPP rate, EI rate, federal brackets, provincial BPAs, and more.
After review, click Apply…, confirm the disclaimer, and the module writes the new values into
hr.rule.parameter with the correct effective
date. Payslips computed on or after that date automatically use the new values.
Security & compliance
- Human-approval gate is on by default — nothing changes without your explicit click.
- Every update stores the full JSON payload for audit purposes.
- SHA-256 checksum is verified before any record is created.
- Optional GPG signature verification supported (requires
python-gnupg). - All write access gated by
hr_payroll.group_hr_payroll_manager. - Full chatter history on every update record (who reviewed, who applied, when).
Requirements
- Odoo 19 (Community or Enterprise)
- Requires
l10n_ca_hr_payroll_except_QC(Canada – Payroll, sold separately) - Not available on Odoo Online (SaaS) — Odoo.sh and self-hosted only
What's covered
- CPP employee rate, YMPE, basic exemption
- CPP2 rate, YAMPE
- EI employee premium rate, maximum insurable earnings
- Federal income tax brackets (5 brackets)
- Federal Basic Personal Amount (BPA min / max)
- Provincial/territorial BPA and tax brackets for all provinces except Quebec
Quebec data is out of scope — matches the base l10n_ca_hr_payroll_except_QC module.
Why is this free?
This connector is offered free of charge to support customers of the base
Canada – Payroll (l10n_ca_hr_payroll_except_QC) module and to
encourage adoption of automated, human-approved tax updates. The underlying CRA payroll tax
data is published openly by the Government of Canada under the
Open Government Licence – Canada,
making it straightforward to redistribute in a structured, machine-readable format.
Note: The base Canada – Payroll
(l10n_ca_hr_payroll_except_QC) module is a paid module and is sold
separately. This connector add-on has no standalone function without it.
