How Does PAYE Work for a Small Limited Company in the UK in 2026?

PAYE requires small limited companies in the UK to register with HMRC, deduct income tax and National Insurance from employee salaries, and pay these to HMRC monthly by the 22nd. Employers report via Real Time Information (RTI) submissions before or on payday. This system ensures compliance with tax laws for all paying staff.

What Is PAYE and Who Must Use It?

PAYE stands for Pay As You Earn. Small limited companies use it when they employ staff, including directors, taking salaries. HMRC mandates registration within three months of paying the first employee.

PAYE collects income tax and National Insurance Contributions (NICs) at source. Companies deduct these from wages before paying employees. HMRC receives payments directly.

Small limited companies qualify as employers once they pay salaries. This includes one employee or a director drawing pay. Over 5.6 million UK employers operated under PAYE in 2025.

Directors count as employees for PAYE. Companies register even for single-director setups, paying themselves a salary. HMRC tracks compliance through Unique Taxpayer References (UTRs).

Non-compliance triggers penalties. Late registration incurs £100 fines per employee. Accurate PAYE setup prevents audits and backdated charges.

When Does a Small Limited Company Register for PAYE?

Register for PAYE before or within three months of paying the first employee. Submit online via HMRC's Government Gateway. Approval grants an Employer PAYE Reference in 5-10 working days.

Companies start the process on HMRC's website. Create a Government Gateway account first. Enter company details, including Corporation Tax UTR.

Timing matters for compliance. Pay the first salary, then register immediately. HMRC allows backdating for up to three months if delays occur.

Small limited companies often overlook director salaries. Directors qualify as employees under employment law. Register before the first payroll run.

New companies are formed with Companies House first. Then apply for PAYE. Services like Register Your Company for PAYE handle this process efficiently.

How Do Companies Calculate PAYE Deductions?

Calculate PAYE using HMRC tax tables or Basic PAYE Tools software. Deduct income tax at 20% basic rate up to £50,270, plus 12% employee NICs on earnings over £12,570. Adjust for tax codes like 1257L.

Payroll software automates calculations. Input gross salary, tax code, and NI category. Software applies current rates from HMRC notices.

Income tax rates apply progressively. Basic rate covers £12,571 to £50,270. Higher rate at 40% starts above £50,270. NICs use primary thresholds.

Tax codes determine allowances. Standard 1257L allows £12,570 personal allowance. Companies obtain codes from HMRC or P45 forms.

Small companies use free HMRC tools. Basic PAYE Tools suits under 9 employees. Larger firms adopt commercial software like Sage or Xero.

Verify calculations monthly. Errors lead to underpayment penalties at 3% annual interest.

Common Tax Codes for Employees

• 1257L: Standard personal allowance.

• 1150L: Reduced allowance for higher earners.

• BR: Tax all income at basic rate.

• 0T: No personal allowance.

How Does RTI Reporting Work in PAYE?

RTI mandates real-time submissions of FPS before or on payday. Include payroll data like gross pay, tax, NICs, and student loans. HMRC uses this for instant compliance checks.

FPS forms the core of RTI. Submit per pay run, even nil payments. Software connects directly to HMRC.

Data fields cover 20+ items. Examples: pay frequency, hours worked, and statutory pay. Accuracy prevents adjustments.

HMRC analyses RTI data live. Triggers alerts for anomalies, like mismatched tax codes. Reduces year-end corrections.

Small companies benefit from automation. 92% of UK SMEs report fewer errors with RTI-compliant software.

Late FPS incurs £100-£400 fines per failure. Consistent submissions build compliance history.

What Are PAYE Payment Deadlines and Penalties?

Pay PAYE monthly by the 22nd electronically or the 19th by post. Quarterly for small employers with an average liability of under £ 1,500. Penalties start at £100 for late filing, plus 3% interest on late payments.

Monthly payers dominate. Calculate cumulative liability. Pay even if zero deductions.

Switch to quarterly if eligible. Apply via HMRC form. An average under £1,500 qualifies most small limited companies.

Penalties escalate. Late payment adds daily interest. Persistent issues trigger HMRC visits.

Interest compounds daily at Bank of England base rate plus 2.5%. The 2026 rate sits at 4.75%.

Directors draw salaries for tax efficiency. PAYE applies from first payment. No exemptions exist.

Family hires require arm's-length pay. HMRC scrutinises excessive salaries. Use market rates from Reed or Indeed data.

Payslips detail gross, deductions, net. Issue monthly or per pay run.

HMRC requires itemised records. Examples: tax codes used, NI numbers, payment dates.

Digital storage suits small companies. Cloud backups ensure access.
