Is it worth outsourcing accounts and payroll for a small business?
For many small businesses, yes. Outsourcing bookkeeping, payroll and accounts to a qualified firm saves time, reduces the risk of HMRC penalties, and often costs less than employing someone in-house. Payroll has strict real-time reporting rules, minimum wage checks, pension duties and statutory pay, and mistakes can be costly. From April 2026, many sole traders and landlords also have to follow Making Tax Digital for Income Tax, which adds quarterly reporting.
What you can outsource
| Task | What’s involved |
| Payroll | Calculating pay, tax and NIC; Full Payment Submissions on or before payday; payslips; P60s |
| Auto-enrolment pensions | Assessing staff, enrolling them, paying contributions, re-enrolment every 3 years |
| Benefits in kind | P11D and P11D(b) by 6 July, or payrolling benefits |
| Bookkeeping | Recording sales and costs, bank reconciliation, VAT returns under MTD |
| Year-end accounts | Company accounts for Companies House and the CT600 for HMRC |
| Self Assessment and MTD | Quarterly updates and the final declaration for sole traders and landlords |
Benefits for small businesses
- Fewer penalties: late FPS, VAT and filing penalties add up quickly.
- Up-to-date rules: rates change every April. For 2026/27, employer NIC is 15% above £5,000, and the National Living Wage is £12.71.
- Time back: owners spend more time running the business.
- Better information: regular management figures help with cash flow and tax planning.
- Cover for absence: no single person holds all the payroll knowledge.
Example
A café with 12 staff spends around 6 hours a month on payroll, rotas and pension uploads, and paid a £400 late-filing penalty last year. An outsourced payroll at, say, £10 per employee per month costs £1,440 a year. That’s less than the owner’s time and the penalty combined, and the bureau also handles statutory sick pay and maternity pay.
What you still need to do
- Give the provider accurate hours, starters, leavers and changes on time
- Approve payroll and pay staff and HMRC
- Keep receipts and records for at least 6 years for companies
- Stay responsible: HMRC still holds the employer liable for errors
Choosing a provider
- Check they’re qualified and regulated by a professional body
- Ask about software, deadlines and how you’ll send information
- Make sure they hold anti-money laundering supervision
- Agree what’s included in the fee and what costs extra
Data protection
Payroll involves personal data, so your provider must comply with UK GDPR. Agree a data processing contract and check how information is sent and stored.
Signs you need help
Regular late payroll, staff queries about pay, missed pension deadlines or a backlog of receipts are all signs it may be time to outsource. So is a new duty, such as Making Tax Digital or payrolling benefits.
Statutory payments
A good provider also handles statutory sick pay, maternity, paternity and shared parental pay, and reclaims what you’re entitled to through your payroll submissions.
