What does this benchmark actually check?

We built this benchmark for one job: to tell you whether a UK payroll platform clears the statutory bar before it reaches your shortlist. It assesses HMRC recognition, Real Time Information (RTI) submission, auto-enrolment pension processing, and the statutory payments your software has to calculate every pay run.

RTI is the system that requires you to report pay and deductions to HMRC on or before each payday, rather than once a year. Auto-enrolment is the legal duty to enrol eligible staff into a workplace pension and contribute to it.

Both run through your payroll software, so a gap in either one becomes your compliance problem, not the vendor's.

This index covers UK in-country payroll software: the tools UK employers use to run their own PAYE. It is separate from the global employer-of-record and international payroll providers we cover in other Whichapp Research indices.

Which UK payroll platforms are HMRC-recognised?

We checked each platform below against HMRC's published recognised-software list, the version dated 24 April 2026, and recorded the exact corporate entity each product files under. Most rival roundups give you a flat "all recognised" list with no entity named and no date. That is the difference between a claim and a check.

Source: GOV.UK, "Find payroll software that is recognised by HMRC", list dated 24 April 2026. Each platform was matched to its named supplier entry on that list. Recognition status can change; re-check the live list before you sign.

All 10 platforms on our corrected roster are recognised. That is not the reassurance it sounds like, and the next section explains why.

For your shortlist, the practical read is simple: recognition is the floor, not the differentiator. If a platform is not on this list, drop it; if it is, you have only cleared the first gate.

Does HMRC recognition mean the software calculates PAYE correctly?

No, and this is the point most roundups miss. HMRC recognition confirms that a product has passed HMRC's technical testing for filing RTI submissions. That means the Full Payment Submission (FPS) you send on payday and the Employer Payment Summary (EPS) you send to reclaim statutory payments or report a nil payment.

In short, it tests that the software can talk to HMRC's gateway in the right format.

It does not audit whether the software calculates your PAYE tax, National Insurance, or statutory pay correctly. HMRC states plainly that it "cannot recommend one product or service over another" and is "not responsible for any problems you have with software you've bought". Recognition is a compatibility tick, not a kite-mark for accuracy.

Here is why that matters to you. When a vendor's sales deck leads with "HMRC-recognised", your finance team may read it as a guarantee that the numbers will be right.

They will not get that from the GOV.UK list, and neither will you. The calculation accuracy still has to be tested, which is exactly what our full benchmark does.

Why did we change the platforms in this benchmark?

Our first version of this roster did not survive its own audit, so we rebuilt it. We are showing the working because a clean roster is part of the data, not housekeeping you should have to take on trust.

Three problems forced the change. 12Pay was discontinued on 5 April 2025 and is no longer a live product, so it cannot be benchmarked and it does not appear on the current HMRC list. We removed it.

Next, the roster double-counted one vendor. IRIS now owns and sells Staffology Payroll, which is 12Pay's effective successor, alongside its own IRIS Payroll Professional. We kept both because they are separately marketed products, but we label the shared owner so you are not misled into thinking they are independent options.

Finally, Paysuite could not be matched to any current entry on the HMRC list, so asserting it was recognised would have been a guess. We replaced it, and OneAdvanced now stands in as a live, separately-owned platform we could verify. We would rather tell you what we could confirm than pad the table.

What statutory figures must the software get right in 2026/27?

Every recognised platform supports statutory payments. The question that decides a real pay run is whether it applies the current rates and the daily and weekly mechanics correctly. These are the 2026/27 figures your software has to produce without you checking by hand.

If you are running a team where someone is on maternity leave and another is off sick in the same month, this is the moment the software earns its fee. A platform that automates the SSP waiting-day logic and the SMP 90%-then-flat-rate switch saves you a manual recalculation that is easy to get wrong and awkward to explain to the employee when it is.

What should you do with this before you shortlist?

Confirm HMRC recognition yourself against the live GOV.UK list on the day you shortlist. Recognition can be withdrawn if a provider fails re-testing after a PAYE rule change, so a tick from last quarter is not a tick today. Our table gives you the entity name to search for, which makes that check quick.

Then push past the tick. Ask each vendor to demonstrate a live SSP and SMP calculation in a sandbox, and ask whether auto-enrolment declarations and contribution uploads are automated or manual. The manual versions are where staging-date failures and late-payment penalties start, and that is the risk your procurement team is signing off.

One more for the shortlist committee. If a platform shares an owner with another on your list, say so in the paper. Presenting IRIS Payroll Professional and Staffology as two independent choices when one company controls both is the kind of detail Legal will catch later, and it is better coming from you.

What will the full benchmark add in Q3 2026?

This v2 index gives you verified recognition and the statutory rates that matter. The full benchmark in Q3 2026 will add the calculation-accuracy testing that recognition does not cover:

• Structured test-case results for RTI FPS, EPS, and Earlier Year Update submission accuracy
• Statutory payment calculation accuracy (SSP, SMP, SPP, ShPP, SPBP) tested against HMRC's own calculators
• Auto-enrolment declaration and contribution-upload automation depth, scored per platform
• P60, P45, and P11D generation against HMRC format specifications

Limitations and open data points

• This v2 index covers 10 platforms and verifies recognition only. Calculation accuracy is tested in the Q3 2026 release, not here.
• HMRC recognition was verified against the list dated 24 April 2026. The list changes frequently; check the current version before finalising a platform.
• HMRC has signalled a move toward mandatory payrolling of most benefits in kind, which will change P11D reporting. We have not stated a commencement date here because we could not verify one from a primary source at the time of writing. We will confirm and add it in the next refresh rather than print an unverified date.
• This benchmark covers statutory compliance, not wider product features such as reporting, integrations, or user experience.
