If employer National Insurance is now 15% and kicks in sooner, the difference between “set and forget” payroll and a quarterly tax-planning rhythm can be thousands. In this guide, you’ll see what to check every quarter, how to claim Employment Allowance (EA) correctly, and how to handle benefits-in-kind (BiKs) without nasty July/October surprises.


Who this is for

UK SMEs with 5–30+ staff who value proactive, compliant payroll and want to keep more of what they earn not those chasing the cheapest fee.


What you should check every quarter

QuarterWhat to doWhy it matters
Q1 (Apr–Jun)Switch on/confirm EA claim in your EPS; check you’re eligible (single-director-only payrolls stay excluded; connected companies: only one claim). Decide if you’ll voluntarily payroll benefits from April and map any exceptions (e.g., accommodation and beneficial loans).EA reduces ongoing employer NIC bills throughout the year if it’s active from month one. Voluntary payrolling spreads employee tax in-year and simplifies July admin.
Q2 (Jul–Sep)By 6 July: file P11D/P11D(b) and give employees their benefit statements. By 22 July (online): pay Class 1A NIC. Reconcile any “making good” by 6 July. Submissions must be electronic.Avoid penalties/interest and tidy prior-year benefits before the summer break.
Q3 (Oct–Dec)By 22 Oct (online): pay PSA tax + Class 1B if you use a PAYE Settlement Agreement. Mid-year benefits data audit and software readiness for 2027.Smooths cashflow and prevents year-end pile-ups; gears you for mandatory payrolling.
Q4 (Jan–Mar)Lock next-year approach: confirm which BiKs you’ll payroll from April; line up employee comms; re-confirm EA eligibility and that your EPS claim will roll into the new year.Hit 6 April with everything switched on; no missed savings in April/May payrolls.

What you get
EA lets eligible employers reduce their employer Class 1 NIC by up to £10,500 in the tax year; it’s used up as you run payroll until exhausted or year-end.

How to claim (EPS)

Pro tip: Switching EA on in April maximises in-year cash benefit; switching late compresses savings into fewer pay runs (see Scenario A below).

Two short, practical scenarios

Scenario A: EA switched on in April vs in Month 12

Profile: 18-staff service SME; 2025/26 secondary NIC at 15% with £5,000 ST. GOV.UK

Takeaway: Make EA part of your Q1 checklist to pull forward savings and smooth cashflow.


Scenario B: Private medical: payroll now or P11D in July?

Profile: 12 employees, each with £600/year private medical.

Takeaway: For most SMEs, payrolling gives cleaner monthly deductions and fewer employee queries, while your Class 1A remains a July cash item to budget for.
