    Becoming an Employer + PAYE Scheme Registration — LEL £123/week 2025/26

    You must register as an employer with HMRC and operate a PAYE scheme as soon as you pay anyone at or above the Lower Earnings Limit (LEL: £123/week / £533/month / £6,396/year for 2025/26), OR pay any director, OR provide expenses or benefits-in-kind to any worker, OR engage someone who already has another job or pension. The trigger is LEL — NOT the secondary threshold (£5,000) and NOT the personal allowance (£12,570). Register via HMRC PAYE Online before the first payday. Allow 4-6 weeks lead time: HMRC typically issues the employer PAYE reference + Accounts Office reference within 5 working days but can take 10+.

    In plain English

    The single most-misunderstood point: the PAYE trigger is the Lower Earnings Limit (LEL), not the personal allowance or the secondary NI threshold. For 2025/26 the LEL is £123/week (£6,396/year). The moment you pay anyone at or above that level, you must operate a PAYE scheme. Even below LEL, you trigger PAYE if you pay any director, provide any taxable benefit/expense, or engage someone with another job or pension (because their other employment uses up the personal allowance — you need a tax code to deduct correctly). Don't conflate this with the Class 1 secondary NIC threshold (£5,000 from April 2025) — that is the point at which employer NI starts to bite, not the point at which a PAYE scheme is required. Register via HMRC PAYE Online before the first payday. HMRC issues two references: the Employer PAYE reference (e.g. 123/AB45678) and the Accounts Office reference (e.g. 123PA00012345). You need both for RTI submissions and payment. Allow 4-6 weeks lead time — most registrations come back in 5 working days but 10+ is common in busy periods.

    How it works

    Identify the trigger

    Run through: (a) am I paying anyone at or above £123/week? (b) am I paying any director? (c) am I providing any taxable BiK or expense? (d) is anyone I am paying also employed or in receipt of a pension elsewhere? Any 'yes' = register for PAYE.

    Register via HMRC PAYE Online

    Set up a Government Gateway business account. Apply for PAYE for Employers via the 'Get an employer PAYE reference' route. Provide: business name; trading address; UTR (if any); date first employee starts; estimated number of employees; payment frequency. Online registration only; no paper alternative for new schemes.

    Wait for credentials

    HMRC posts the Employer PAYE reference + Accounts Office reference. Typical 5 working days; allow up to 4 weeks. Do NOT make first PAYE payment to HMRC until you have the Accounts Office reference — payments without it route incorrectly and require manual reallocation.

    Choose payroll software

    Options: (a) HMRC Basic PAYE Tools — free, suitable for up to 9 employees; (b) commercial payroll (FreeAgent / Xero / QuickBooks / Sage / BrightPay / Moneysoft / IRIS — categorical reference only). Software must be HMRC-recognised for RTI submission. Confirm Auto-Enrolment integration (TPR Declaration of Compliance is a separate submission).

    Pre-first-payday checklist

    Employer Liability Insurance (Employers' Liability (Compulsory Insurance) Act 1969 — min £5m cover; mandatory subject to narrow family-employee exception); written statement of employment particulars (day-one ERA 1996 s.1); pension scheme chosen + assessed; right-to-work check (Immigration, Asylum and Nationality Act 2006); GDPR-compliant employee data handling.

    Who this applies to + key conditions

    Statute + manual references

    Primary: Income Tax (Earnings and Pensions) Act 2003 + Income Tax (Pay As You Earn) Regulations 2003 (SI 2003/2682) — the PAYE regime.

    Related: Social Security Contributions and Benefits Act 1992 — LEL + Class 1 NICs; Social Security (Contributions) Regulations 2001 (SI 2001/1004); Finance Act 2013 + Schedule 24 — RTI penalty regime (refined by Sch 24 FA 2021); Income Tax (Construction Industry Scheme) Regulations 2005 — separate CIS scheme triggered by construction subcontractor payments

    Common mistakes + traps

    Worked example

    Priya, sole trader plumber, hires her first apprentice on £200/week

    Priya has run her plumbing business as a sole trader for 3 years. From 1 June 2025 she hires Sam, age 18, as an apprentice on £200/week (above LEL £123/week — PAYE triggered). Sam has no other job. Priya has no other employees.

    1. Step 1 — Confirm trigger: £200/week ≥ LEL £123/week → PAYE scheme required.
    2. Step 2 — Register for PAYE Online by mid-April (target 4-6 weeks before 1 June start).
    3. Step 3 — Receive PAYE reference (e.g. 475/PQ12345) + Accounts Office reference (475PA00067890) by ~late April.
    4. Step 4 — Choose payroll software (HMRC Basic PAYE Tools free, fits Priya's 1-employee scheme).
    5. Step 5 — Arrange Employers' Liability Insurance (£5m min); choose AE pension scheme (NEST is default; Sam is 18 so below AE eligibility age 22, but Priya must still assess monthly).
    6. Step 6 — Apprentice NMW rate £7.55/hour (Sam is 18, in first year, so apprentice rate applies); £200 / 30hr week ≈ £6.67/hour BELOW £7.55 — must increase to avoid NMW breach.
    7. Step 7 — Issue Sam written statement of employment particulars on day one (ERA 1996 s.1).
    8. Step 8 — Submit FPS on or before each payday; pay PAYE + NIC monthly by 22nd (electronic) / 19th (post).

    Outcome: Priya is PAYE-registered with HMRC, has lawful employment infrastructure, must adjust Sam's pay to clear apprentice NMW, and operates Basic PAYE Tools at zero software cost.

    How this connects to the rest of the framework

    RTI mechanics →

    Once registered, FPS and EPS submissions become the operational core of PAYE.

    Employer NICs 2025/26 →

    Class 1 employer NI starts at the £5,000 secondary threshold — different from the PAYE registration trigger.

    Pension auto-enrolment →

    PAYE registration triggers AE duties when you hire eligible workers — separate TPR submission.

    CIS for contractors →

    If you operate in construction, you also need a separate CIS scheme for subcontractor payments.

    Employee vs worker vs self-employed →

    Determine status before assuming PAYE — true self-employed engagements stay outside PAYE.

    Frequently asked questions

    What happens if I miss the Self Assessment deadline?+
    The Self Assessment deadline is 31 January (online filing) for the previous tax year. Miss it and HMRC apply an automatic £100 penalty. Beyond that: £10 per day from 3 months late (capped at £900), 5% of tax due at 6 months late, and another 5% at 12 months late, under Schedule 55 of the Taxes Management Act 1970. If you have a genuine reason (serious illness, bereavement, technical issue with HMRC's systems) you can appeal with evidence; HMRC accepts reasonable excuse appeals in most genuine cases.
    Do I need an accountant or can I file Self Assessment myself?+
    Legally you can file Self Assessment yourself via gov.uk for free, most simple sole-trader returns (single income source, basic expenses) are realistic to self-file. An accountant adds real value when: your trading profit is above £40,000 (extraction-strategy decisions matter), you have multiple income streams (PAYE + self-employment + property + dividends), you've crossed the £90,000 VAT threshold, you're considering incorporation, or you have an HMRC enquiry. Expect to pay £400-£1,500/year for a typical sole-trader accountant; the cost is itself a deductible expense.
    How do payments on account work?+
    When your Self Assessment tax bill exceeds £1,000 for the first time, HMRC requires payments on account toward NEXT year's tax. Half the current bill is due 31 January (alongside the current bill); the other half is due 31 July. So your first January after crossing the threshold can hit with a double-bill: last year's balance + first payment on account. Adjust via Form SA303 if you expect next year's income to drop substantially. Payments on account don't apply if more than 80% of your tax is collected via PAYE.
    What if I'm paying someone under £123/week — do I still need PAYE?+
    Only if they have another job/pension (need a tax code) OR you're paying a director OR providing benefits. Otherwise no PAYE scheme required, but you must keep records of payments.
    How long does PAYE registration take?+
    Typically 5 working days; allow 4-6 weeks before first payday to be safe.
    Can I use HMRC Basic PAYE Tools?+
    Yes if you have up to 9 employees. Free, HMRC-supported, RTI-compliant. Beyond 9 employees, switch to commercial payroll software.
    Do I need to register for CIS at the same time?+
    Only if you operate in construction and pay subcontractors. CIS is a separate scheme to PAYE.
