Payroll tax filing and remittance, built into your PrismHR workflow
TaxRails connects to PrismHR over API and takes payroll tax off your team's plate — every EIN, every client, every jurisdiction. We create the return, submit it to the agency, and remit the payment from your accounts on the date it's due.
TaxRails is an independent platform. PrismHR is a trademark of its respective owner and this integration is not an endorsement.
The hard part of PEO payroll tax isn't the math
PrismHR calculates payroll accurately. The pain shows up afterward — hundreds of client EINs, thousands of jurisdiction-level obligations, and a tax team logging into portals to make deposits by hand.
Multi-EIN by design
Whether you file under your own FEIN, client-level EINs, or a mix of both across states, TaxRails models the structure you actually operate — including client-specific SUI experience rates.
No more portal-by-portal deposits
Your team stops maintaining a spreadsheet of logins, due dates, and confirmation numbers. TaxRails submits and captures proof of filing for every obligation automatically.
Headcount that scales sublinearly
Adding clients stops meaning adding tax staff. The work that grows with your book — filing, depositing, notice handling — moves to infrastructure.
From PrismHR pay run to filed return
API connection and entity mapping
We authenticate to your PrismHR tenant and map your client hierarchy, EINs, worksite locations, and existing state and local registrations into TaxRails.
Automatic pay run sync
As each payroll finalizes in PrismHR, wage and tax detail flows to TaxRails — withholding, employer liabilities, and taxable wages resolved to the jurisdiction level.
Filing and submission
TaxRails builds each federal, state, and local return on the correct cadence, submits it, and stores the agency confirmation against the client and period.
Remittance from your accounts
Deposits go out by ACH on the due date from the bank account you designate. Your funds — and the float — stay with you until the money is legally owed.
PrismHR shops that fit well
PEOs
Co-employment filing across many states, with the client-level reporting your service team needs to answer questions without escalating to tax.
ASOs
Filing under each client's own EIN, at scale, without one tax specialist per hundred clients.
Payroll service bureaus
Offer tax filing and remittance as a first-class product line rather than a service you absorb the risk on.
PrismHR integration FAQ
Yes. PrismHR stays your platform for HR, payroll processing, and client management. TaxRails takes over what happens to the tax liabilities it produces.
Yes. Experience rates are tracked per EIN and state, with effective dates, so mid-year rate notices apply to the right periods and quarterly contributions come out correct.
We work the notice — trace it to the underlying period and filing, prepare the response or amendment, and tell you what happened. You get the resolution, not a forwarded PDF.
Yes, and most do. We load year-to-date wage and deposit history so quarterly and annual reconciliations tie out, and we sequence the cutover around quarter boundaries wherever it reduces risk.
