Which PAYE thresholds must UK small businesses know in 2026?

Yes. The PAYE threshold in the UK refers to six key numeric limits small businesses must track: the Employer PAYE threshold (£0 for registration), National Insurance secondary threshold (£9,100 per year for 2026/27), National Insurance primary threshold (£12,570 per year), Lower Earnings Limit (£6,396 per year), Earnings Upper Secondary Threshold (£50,270 per year), and Student Loan thresholds which vary by plan.

What numeric PAYE thresholds must small businesses track?

Small employers must monitor six numeric thresholds: registration point, National Insurance secondary threshold, National Insurance primary threshold, Lower Earnings Limit, Upper Earnings Threshold, and student loan repayment thresholds.

Small businesses must register as employers with HMRC before the first payday. Employers must calculate employee tax and National Insurance (NI) against these thresholds every pay period. Tracking prevents incorrect tax reporting, penalties, and missed contributions.

What is the employer PAYE registration threshold?

There is no minimum earnings threshold for registering as an employer; registration is required before the first payment to staff.

Register your company for PAYE with HMRC once you hire anyone as an employee, including directors who receive pay. Registering triggers obligations: report payroll, operate PAYE, and submit Full Payment Submissions (FPS). Late registration incurs penalties and late-pay liabilities.

What is the National Insurance secondary threshold for employers?

For 2026/27, the employer (secondary) NI threshold is £9,100 per year; employers pay Class 1 employer contributions above this.

Employers calculate Class 1 employer National Insurance at the applicable rate on earnings above the secondary threshold. Use payroll software to apply the threshold per pay period or use monthly/weekly equivalents: £175 per week or £758.33 per month. Accurate application ensures correct employer NI contributions and reduces audit risk.

What is the National Insurance primary threshold for employees?

For 2026/27, the primary (employee) NI threshold is £12,570 per year; employees begin paying Class 1 contributions above this level.

Payroll must deduct employee NI at the correct rate on earnings above £12,570 per year. Apply weekly/monthly equivalents: £242 per week or £1,047.50 per month. Correct deductions affect net pay calculations and statutory benefit entitlements, such as qualifying years for the state pension.

What is the Lower Earnings Limit (LEL) and why does it matter?

The LEL for 2026/27 is £6,396 per year; earnings at or above this count towards certain contributory benefits even without NI deductions.

Employers must record earnings between the LEL and primary threshold to credit employees with NI contributions for benefits eligibility. No NI is deducted from earnings between the LEL and the primary threshold, but reporting is required. This impacts employee entitlement to maternity, sickness, and state pension credits.

What is the Upper Earnings Threshold employers should know?

The Upper Earnings Threshold for 2026/27 is £50,270 per year; employee NI above this is charged at a lower rate for the higher-rate band.

Payroll systems apply the appropriate NI rates when employee earnings cross the upper threshold. Employers must split calculations: primary contributions between the primary threshold and upper threshold, and the upper-rate contributions above it. This affects take-home pay, tax codes, and PAYE reporting.

What student loan and other repayment thresholds apply?

Student loan repayment thresholds vary by plan: Plan 1 (£22,015), Plan 2 (£27,295), Plan 4 (£27,660), and Plan FE (£25,000) for 2026/27; deductions occur on earnings above each threshold.

Employers deduct student loan repayments via payroll when earnings exceed the employee’s plan threshold. Verify the employee’s plan on starter forms or HMRC records. Apply the correct percentage rate per plan to calculate monthly deductions and include them on payslips and FPS submissions.

How do pay period equivalents affect threshold application?

Convert annual thresholds to weekly or monthly equivalents: weekly = annual/52, monthly = annual/12; apply the equivalent for each pay frequency.

Use exact conversions in payroll software to calculate per-pay-period thresholds. For example, the primary threshold weekly equivalent is £242 (annual £12,570 ÷ 52). Incorrect conversion causes under- or over-deductions and triggers compliance errors during PAYE reconciliation.

How does PAYE interact with directors’ pay and company dividends?

Directors often use a different pay reference period, apply thresholds across the whole tax year and use an annual basis when required.

Directors paid via PAYE commonly have an annual pay reference period for NI and tax calculations. Payroll must handle annualised earnings to determine National Insurance correctly. Dividends fall outside PAYE; do not deduct NI from dividends. Treat dividends as separate in company accounts and tax filings.

What payroll steps ensure threshold compliance?

Register for PAYE, set correct tax codes, configure NI thresholds in payroll software, deduct student loans, submit FPS on time, and reconcile with Employer Payment Summary (EPS).

Maintain accurate employee records and use HMRC guidance for tax codes and thresholds. Run payroll tests before the first pay run. Submit FPS on or before each payday. Send EPS when adjustments occur. Reconcile payroll with payslips, P60s, and year-end returns to avoid penalties.

How do Real Time Information (RTI) and thresholds connect?

RTI requires employers to report PAYE data to HMRC each pay period, using accurate threshold calculations for tax, NI, and student loans.

Every FPS must include taxable pay, NI contributions, and student loan deductions that reflect threshold rules. Use payroll software compliant with RTI. RTI reporting ensures HMRC receives up-to-date payroll figures for tax credits, Universal Credit assessments, and employer records.

What penalties relate to threshold and PAYE errors?

HMRC issues penalties for late registration, late FPS/EPS filing, incorrect PAYE deductions, and late or incomplete payments; fines scale by size and recurrence.

Penalties include fixed fines for late FPS and percentage-based penalties for late payments. Accurate threshold application reduces the risk of misreported NI and tax, which are common penalty drivers. Maintain records for three years plus the current year to support any HMRC queries.
