HMRC RTI Payroll — File FPS & EPS Without Leaving Carionex
Process payroll and submit Full Payment Submissions and Employer Payment Summaries directly to HMRC — with Government Gateway authentication, automatic XML generation, IRmark validation and a complete submission audit trail.
Real Time Information, done for you
Under Real Time Information (RTI), you must report pay and deductions to HMRC on or before each payday. Carionex builds RTI straight into payroll, so once you've run pay you can file your FPS in the same place — no exports, no third-party bridging software.
Government Gateway authentication, automatic XML generation, IRmark validation and a full submission audit trail are all handled for you. The integration has been successfully validated against HMRC's Electronic Test Service (ETS).
The problems this solves
- Juggling payroll and separate HMRC submission tools
- Manual XML or bridging software for RTI
- No clear audit trail of what was submitted and when
- Uncertainty about whether a submission actually succeeded

Frequently asked questions
What is HMRC RTI?+
Real Time Information (RTI) is the system for reporting pay, tax and National Insurance to HMRC on or before each payday, primarily through the Full Payment Submission (FPS). Carionex files these submissions directly.
Can Carionex submit FPS and EPS to HMRC?+
Yes. You can submit both Full Payment Submissions (FPS) and Employer Payment Summaries (EPS) to HMRC directly from Carionex as part of your payroll process.
Do I need separate bridging software?+
No. RTI is built into Carionex payroll, so you don't need third-party bridging software or manual XML exports to file with HMRC.
How does authentication with HMRC work?+
You authenticate securely using your Government Gateway credentials, and Carionex handles the connection to HMRC for you.
What is IRmark and does Carionex handle it?+
IRmark is a digital fingerprint HMRC uses to verify a submission's integrity. Carionex generates and validates the IRmark automatically before submitting.
Is the integration tested with HMRC?+
Yes. The RTI integration has been successfully validated against HMRC's Electronic Test Service (ETS).
Is there a record of what I submitted?+
Yes. Every submission is stored in a complete audit trail with its timestamp, contents and the response received from HMRC.
