Payroll · declaration comparison

Starter declaration A vs B vs C comparison before first FPS goes in.

Payroll errors often start because the team remembers the labels A, B and C but not the situation each one is meant to represent. This comparison page helps slow that decision down.

Direct answer

Match the employee's real PAYE situation to declaration A, B or C before you set the tax code and first FPS record.

HMRC guidance is authoritative. This page is a payroll operations comparison and not tax or legal advice.

Source base: HMRC starter checklist guidance, Work out your new employee's tax code and HMRC PAYE manual on statements A, B and C.

A/B/C comparison points

Check	What to compare	Why it matters
Employee situation	Which statement actually matches the employee's work and benefits history since 6 April.	The declaration choice affects the starting tax treatment.
Source data	Whether you are working from a recent P45 or the starter checklist answers.	You need the right source before making the A/B/C call.
First payroll setup	How the declaration is recorded in the starter record and first FPS.	The first submission can lock in the wrong path if the declaration is wrong.
Later update	What changes if a P45 or HMRC notice arrives later.	Reduces panic edits after the first pay run.
Audit file	Whether the completed checklist or explanation is retained.	Useful when someone later asks why A, B or C was chosen.

Choice

Statement labels are not enough.

The choice only works if it reflects the employee's real PAYE position.

Timing

Decide before FPS.

Fixing a wrong declaration after first submission is messier than getting it right upfront.

Boundary

Edge cases exist.

Overseas arrival, multiple jobs or complex benefits may need extra review.

A/B/C comparison workflow

Collect the starter answers or recent P45 before payroll setup.
Compare the employee's situation against the A, B and C statements carefully.
Enter the matching declaration once in the starter record.
Keep the completed checklist or supporting note with payroll records.
Apply later HMRC or P45 updates without recreating the starter event.

FAQ

Is declaration B just the middle option if I am unsure?: No. The declaration should match the employee's actual circumstances, not a fallback guess.
Do I still need the employee's core data if I know the declaration?: Yes. Identity and start data still matter for the payroll record and FPS.
Is this official payroll instruction?: No. HMRC guidance controls.
