What is RTI?
Real Time Information (RTI) is how employers report payroll information to HMRC. Every time you pay an employee, you must submit a Full Payment Submission (FPS) to HMRC on or before the payday.
At the end of the tax year (or when an employee leaves), you submit an Employer Payment Summary (EPS) to finalise the year's figures.
ByteLogic's free tier generates FPS XML files that you can upload to HMRC manually. Direct RTI submission is coming soon in our Pro tier, pending HMRC vendor approval.

Why is ByteLogic Free?
We believe every small business should have access to professional payroll and accounting software. With IRIS Payroll Basics discontinued and Basic PAYE Tools lacking payslips and auto-enrolment, thousands of micro-businesses need modern alternatives.
Our free tier covers payroll (up to 5 employees), bookkeeping, reports, dividends, director's loan tracking, pension auto-enrolment, invoicing (up to 10/month), and time tracking. No credit card required. We make money from our Pro tier (£19/month) which adds direct HMRC submission, Open Banking, VAT MTD, Corporation Tax filing, and more.
