Highlights
- A client inherited from a previous provider had incorrectly claimed Small Employers’ Relief (SER) before Corient took over.
- Corient identified the overclaim, corrected it through an amended RTI submission, and kept the client fully HMRC-compliant.
- A mid-process SMP claim added complexity and financial pressure — but proactive planning meant the client was never caught off guard.
- The overclaim was fully adjusted, interest exposure was minimised, and the client stayed compliant throughout.
Introduction
Payroll compliance rarely announces itself as a problem — until it does. For one client who transitioned to Corient, the issue was already sitting quietly in the background: a Small Employers’ Relief (SER) claim had been ticked under the previous provider, for a client who was never actually eligible to claim it. It was the kind of legacy error that’s easy to miss and expensive to leave unresolved. Here’s how Corient found it, fixed it, and turned a compliance risk into a compliance win.
The Initial Problem: What Went Wrong?
When Corient took over the client’s payroll, a routine review surfaced something that didn’t add up: SER had been claimed in a prior RTI submission, but the client didn’t meet the eligibility criteria. This wasn’t a new error — it predated Corient’s involvement — but it was now Corient’s responsibility to fix, since an unresolved overclaim meant the client was technically out of step with HMRC requirements, with the liability quietly growing in the background.
Corient’s First Solution: The Fix
The path forward was clear in principle: unclaim the SER allowance and submit an amended RTI to reflect the correction. This would bring the client’s records back in line with what they were actually entitled to, closing the compliance gap left by the previous provider.
The New Problem: A Surprise Roadblock
As the team began implementing the fix, a complication emerged. Statutory Maternity Pay (SMP) had already been processed for the client, and additional claims had been made on top of it. Correcting the SER overclaim now meant recalculating liability across an interconnected set of figures — and any unpaid balance left after the adjustment would immediately start accruing interest, charged on a daily basis. What started as a straightforward correction now carried real financial stakes if it wasn’t handled carefully and quickly.
Corient’s Second Solution: Fixing the New Problem (Step-by-Step)
- Recalculate the full picture first. Before making any submission, Corient’s team worked out the complete adjusted liability, factoring in the SER reversal alongside the existing SMP claims.
- Prepare the working papers in advance. A clear, detailed breakdown of the adjustment was put together so the client could see exactly what was owed and why — no surprises, no ambiguity.
- Flag the balance early. The client was informed ahead of time to keep the required payment ready, so there would be no delay once the correction went live.
- Submit the amended RTI. With the groundwork done, Corient reclaimed the SER allowance and filed the amended submission with HMRC.
- Coordinate prompt payment. Because the client was prepared in advance, the outstanding balance was paid immediately after the adjustment was processed — cutting the window for daily interest to accrue down to a minimum.
The Final Outcome: Success Story
The overclaim was fully adjusted, and the client’s payroll records were brought back into compliance with HMRC’s requirements. By preparing the financial picture ahead of the correction, Corient avoided the drawn-out interest exposure that often accompanies retrospective adjustments — turning what could have been a stressful, costly cleanup into a smooth, well-managed fix.
“We inherited a problem we didn’t create, but Corient handled it like it was their own from day one. They didn’t just fix the numbers — they made sure we knew exactly what to expect and when. There were no last-minute scrambles, just a clear plan we could follow.”
Key Takeaways: Why This Matters for Businesses
- Legacy errors don’t disappear with a change of provider — they need to be actively found. A thorough review at handover is what surfaced this issue in the first place.
- Compliance corrections can have financial side effects. Adjusting one claim can affect connected figures like SMP, so corrections need to be assessed holistically, not in isolation.
- Preparation prevents penalties. Getting ahead of the payment requirement meant the client avoided unnecessary interest charges.
- Transparency builds trust. Sharing the working papers and expected balance in advance turned a potentially stressful correction into a controlled, predictable process.
Proactive planning turns compliance corrections from a costly scramble into a smooth, manageable process.
