Submit RTI to HMRC (FPS & EPS)
File payroll Real Time Information straight to HMRC — an FPS every payday, an EPS when you need one. No re-keying into Basic PAYE Tools.
Direct PAYE RTI submission from AccountsOS: Full Payment Submission (FPS) and Employer Payment Summary (EPS) sent to HMRC's Transaction Engine over the GovTalk protocol, signed with a verified IRmark, using your employer Government Gateway credentials. The submission engine is built and the IRmark is verified against HMRC's published 2025-26 test vectors; we're completing HMRC RTI recognition now. Until it goes live, AccountsOS runs your payroll, posts it to the ledger and generates the RTI-ready FPS.
In short
Direct RTI submission to HMRC is coming to AccountsOS. You'll file your Full Payment Submission (FPS) on or before each payday and an Employer Payment Summary (EPS) for Employment Allowance or nil-payment months, straight from AccountsOS to HMRC's Transaction Engine — no exporting a file and re-keying it into Basic PAYE Tools. The submission engine is already built and the IRmark (HMRC's submission fingerprint) is verified against HMRC's own published test data; we're going through HMRC's RTI recognition process now. Today AccountsOS runs payroll, emails payslips, posts to the general ledger and generates the RTI-ready FPS.

Frequently Asked Questions
Can AccountsOS submit RTI to HMRC?
Direct RTI submission is coming soon. The submission engine is built and the IRmark is verified against HMRC's published test vectors; we're completing HMRC's RTI recognition process now. Today AccountsOS generates the RTI-ready FPS and runs your payroll, payslips and ledger — once recognition is granted you'll file the FPS and EPS straight to HMRC from the same place.
What is an FPS and an EPS?
A Full Payment Submission (FPS) tells HMRC what you paid each employee and the tax and National Insurance deducted; it must reach HMRC on or before each payday. An Employer Payment Summary (EPS) reports things that aren't on the FPS — claiming Employment Allowance, a month where you paid no one, or recovering statutory pay.
Is this an alternative to Basic PAYE Tools?
Yes. HMRC's free Basic PAYE Tools makes you key every figure in by hand and can't import a file from other software. AccountsOS already runs the payroll, so when direct submission goes live you file the FPS and EPS without exporting or re-keying anything.
Do I need separate payroll software to file RTI?
No. AccountsOS includes payroll — employees, PAYE/NI/pension calculations, payslips and GL posting — and direct RTI filing is being added on top, so payroll and filing live in one product.
How will AccountsOS connect to HMRC for RTI?
RTI uses your employer Government Gateway user ID and password (the PAYE online login), not the Making Tax Digital connection. You'll enter them once; they're stored encrypted and used only to file your submissions to HMRC's Transaction Engine.
Is RTI part of Making Tax Digital?
No. Real Time Information is HMRC's payroll reporting system and is separate from Making Tax Digital, which covers VAT (live) and Income Tax (from April 2026). AccountsOS already files MTD VAT returns and is adding direct RTI payroll filing.
When will direct RTI submission be available?
It's in HMRC's recognition process now. We'll switch it on as soon as recognition is granted. Until then you can run payroll and generate the RTI-ready FPS in AccountsOS today.
