Keep Workday. Replace the tax filing bottleneck.
TaxRails integrates with Workday over API to take payroll tax filing and remittance off your team — federal, state, SUI, and local. Workday stays the system of record. The deposits, returns, confirmations, and agency notices become someone else's job.
TaxRails is an independent platform. Workday is a trademark of its respective owner and this integration is not an endorsement.
The system of record is solid. The tax layer is manual.
In most Workday shops, payroll tax still ends in exported reports, a shared mailbox of agency notices, and a small team logging into state portals against a calendar. That's not a Workday shortcoming — it's a different job than an HCM is built to do.
No re-implementation
This is an integration, not a Workday project. Your configuration, business processes, and reporting stay untouched; TaxRails attaches to the output.
Every jurisdiction, one pipeline
Federal deposits, 50-state withholding, SUI across every registered EIN, and the long tail of local taxes run through one system with one audit trail.
You keep the cash
TaxRails does not impound tax funds. Payments initiate from your accounts on the due date, which at enterprise payroll volume is real working capital and real treasury visibility.
How the Workday integration runs
Secure connection to your tenant
We integrate using Workday's supported integration paths — API and report-based web services — with credentials scoped to the payroll tax data we need and nothing beyond it.
Entity, EIN, and jurisdiction mapping
Your company hierarchy, pay groups, and tax authority setup map to TaxRails entities and registrations. Gaps — unregistered jurisdictions, stale SUI rates — surface during onboarding rather than at quarter close.
Parallel validation
We run alongside your current process for a cycle, reconcile our computed obligations against yours to the penny, and resolve every variance before TaxRails files anything.
Production filing and remittance
Each pay run syncs automatically. Returns are filed on every agency's cadence, ACH deposits go out on the due date, and confirmations plus GL-ready detail come back for reconciliation.
Workday customers who see the biggest change
Large multi-state footprints
Dozens of states plus hundreds of local jurisdictions, where the calendar itself is the risk.
Post-acquisition entity sprawl
Many EINs, inconsistent registrations, and payroll still landing in more than one system.
Lean tax teams
Two or three people carrying the entire filing calendar, with no real coverage when someone leaves.
Treasury-sensitive organizations
Finance teams that want tax dollars staying on their balance sheet until the deposit is legally due.
Workday integration FAQ
No. Workday continues to calculate and process payroll. TaxRails handles what comes next: building the returns, filing them with each agency, remitting the deposits, and owning the notices and amendments.
Light. They provision access and help us validate the data mapping; we build and maintain the integration. There is no custom development to own on your side and no ongoing burden when tax rules change.
Every filing and payment carries entity, jurisdiction, period, and amount detail, exportable for your close. The point is that liability, filing, and cash movement reconcile against each other rather than living in three places.
Access is scoped to the payroll tax data required to file — not your full HCM record — using your tenant's own integration security model. We're happy to walk your security team through the specifics under NDA.
