OUTLINE
Tax Pay is VoPay's new API product for Canadian tax remittance, covering 15 tax types across federal, Ontario, Quebec, and Nova Scotia jurisdictions through a single endpoint, built on the same rails the banks use.
Canadian businesses have been remitting taxes the hard way for too long — manual bank portal entries, fixed-width batch files, and brittle in-house integrations that require deep knowledge of payment-type-specific formats and check-digit algorithms. For payroll and accounting platforms, offering "pay your taxes from inside our product" has historically meant a multi-quarter build.
VoPay Tax Pay changes that. One REST endpoint abstracts the full complexity of government remittances: recipient routing, account number validation, date rules, per-type required fields, and settlement to the correct government recipient — all through VoPay's banking network.
15 tax types across four jurisdictions:
Coverage spans effectively all common Canadian SMB tax obligations outside of CBSA customs duties, which are on the roadmap for a future release.
For product teams at payroll and accounting platforms, Canadian tax remittance has always been a deceptively complex feature to ship. The surface area looks manageable — until you're deep in per-recipient format rules, check-digit algorithms that vary by tax type, provincial holiday calendars, and the reality that errors surface in next-day bank acknowledgement files rather than at submission time. Most teams either deprioritize it, ship a half-measure, or spend quarters building something that's fragile to maintain.
Heads up for integrators
Plan to submit remittances at least 3 business days before the payment due date. This gives a contingency window to catch and resolve any issues before a government deadline is missed. No weekend or Canadian statutory holiday processing.
v1 is API-only - TaxPay launches as a headless, endpoint-driven product. There is no hosted UI in this release — clients integrate POST /remittance/create directly and build their own front-end experience on top. API documentation is available at docs.vopay.com
curl --request POST \
--url https://earthnode-dev.vopay.com/api/v2/remittance/create \
--header 'accept: application/json' \
--header 'content-type: application/x-www-form-urlencoded'
A core design principle of Tax Pay is moving error discovery from after-the-fact to the moment of submission. Every remittance request is validated synchronously, including tax account number check-digit verification, date rules, and per-type required fields, before anything is queued.
If a request fails validation, VoPay returns Success: false with a clear error message and no state is created. Clients can correct the input and retry with the same idempotency key. Final transaction status is delivered via webhook, so there's no need to poll.

Coming Soon: Tax Pay CRA Remittance will be available in the VoPay online portal very soon!
What is CRA tax remittance and how does it work in Canada? CRA tax remittance is the process by which Canadian businesses send collected taxes — such as payroll deductions, GST/HST, and corporate tax installments — to the Canada Revenue Agency. Businesses are legally required to remit on scheduled dates that vary by tax type and remittance frequency. Traditionally, this is done through bank portals or manual batch file submissions. TaxPay automates the entire process through a single API call.
What taxes can I remit through VoPay TaxPay? TaxPay supports 15 Canadian tax remittance types across four jurisdictions: federal CRA (payroll deductions, GST/HST, corporate tax), Ontario (Employer Health Tax, Family Responsibility Office), Quebec via Revenu Québec (payroll source deductions, combined GST/HST + QST, corporate income tax, support payments), and Nova Scotia (WCB premiums). This covers all common Canadian SMB tax obligations in a single integration.
How do I automate CRA payroll remittances from my payroll software? With TaxPay, payroll platforms can integrate a single REST endpoint — POST /remittance/create — to programmatically remit payroll deductions to the CRA directly from their product. No bank portal access, no fixed-width file generation, and no per-recipient format knowledge required. Once integrated, remittances can be triggered automatically at the end of every pay run.
What is the deadline for CRA payroll remittances in Canada? CRA remittance deadlines depend on your remitter type. Regular remitters (average monthly withholding under $25K) remit monthly. Threshold 1 accelerated remitters ($25K–$99,999) remit twice per month. Threshold 2 accelerated remitters ($100K+) remit four times per month. VoPay recommends submitting remittances at least 2 business days before the due date to allow time to resolve any processing issues before the government deadline.
What happens if a CRA remittance is submitted with an error? With TaxPay, most errors, including invalid tax account numbers, incorrect payment dates, and missing required fields, are caught synchronously at the moment of submission and returned immediately in the API response. This means your team is notified right away rather than discovering the problem in a next-day bank acknowledgement file, giving you time to correct and resubmit well before the government deadline.
Does TaxPay support Revenu Québec remittances as well as CRA? Yes. TaxPay supports seven Revenu Québec remittance types, including payroll source deductions across four remittance frequencies, the combined GST/HST and QST return, Quebec corporate income tax, and court-ordered support payment collections. Both federal and Quebec obligations can be remitted through the same API integration.
Can accounting or bookkeeping platforms use TaxPay to remit on behalf of multiple clients? Yes. TaxPay is designed to support multi-client use cases. Accounting platforms, ERP systems, and bookkeeping firms can programmatically remit on behalf of multiple clients, with each remittance tracked by a unique TransactionID that ties to the client's system of record. This replaces manual bank portal entry for every client filing.
Is VoPay TaxPay a hosted portal or a developer API? TaxPay v1 is a headless, API-only product. There is no hosted user interface — it is designed for software platforms and businesses that want to embed tax remittance directly into their own product or internal workflows. Developers integrate the POST /remittance/create endpoint, and the final remittance status is delivered via webhook.
How is VoPay TaxPay different from remitting through a bank portal? Bank portals require manual, one-at-a-time entry with no automation, no audit trail integration, and no real-time error feedback. TaxPay replaces that with a single API call that handles validation, routing, and settlement automatically — across all supported tax types and jurisdictions. Every remittance is tracked by TransactionID, errors surface at submission rather than the next day, and status updates arrive via webhook rather than requiring a login to check.
What Canadian provinces and territories does TaxPay currently support? TaxPay v1 covers federal (CRA), Ontario, Quebec (Revenu Québec), and Nova Scotia. Additional jurisdictions are on the roadmap. CBSA customs duties and import-related payments are not included in v1 but are planned for a future release.
