Quick answer: Outsourced payroll means an accountant runs your PAYE for you — calculating pay, tax and National Insurance, submitting Real Time Information to HMRC on or before every payday, and managing auto-enrolment pensions, payslips, P60s and P11Ds. Bayar Hughes & Co runs weekly and monthly payroll for employers across London from our New Eltham SE9 office.
Why Employers Outsource Their Payroll
Payroll looks simple until you run it. Every pay run involves income tax and National Insurance calculations, student loan deductions, pension contributions, statutory pay entitlements and real-time reporting to HMRC — and every one of those has to be right, on time, every single pay period. Get it wrong and you face unhappy staff, HMRC penalties, or both.
Outsourcing payroll to an accountant removes the burden entirely. You tell us the hours or salary changes; we do everything else — calculations, payslips, HMRC submissions, pension uploads and year-end forms. For most small employers it costs less than the software subscriptions and staff time spent doing it in-house, and it removes the single-person risk of payroll knowledge living in one employee's head.
Real Time Information: What HMRC Expects Every Payday
Under Real Time Information (RTI), employers must send HMRC a Full Payment Submission (FPS) on or before each payday — not weekly, not monthly in arrears, but every time staff are paid. The FPS reports each employee's pay, tax, National Insurance and other deductions.
Where no employees are paid in a tax month, or you need to reclaim statutory payments, an Employer Payment Summary (EPS) is filed instead. Late or missing RTI submissions trigger HMRC penalties that scale with the number of employees, and repeated failures invite closer scrutiny of the whole scheme.
As part of our service, every FPS and EPS is filed on time as a matter of routine — you never have to think about it.

Auto-Enrolment Pensions: Your Legal Duties as an Employer
Every UK employer has automatic enrolment duties from the day their first member of staff starts work. Eligible workers must be enrolled into a qualifying workplace pension, minimum contributions must be paid, and you must complete a declaration of compliance with The Pensions Regulator — then re-assess your workforce and re-enrol eligible staff roughly every three years.
The rules catch employers out in the details: staff who opt out must be handled correctly, postponement has strict notice requirements, and contribution files must match the payroll to the penny. We manage the whole cycle within the payroll run — assessment, enrolment letters, contribution uploads to your pension provider, and the regulator declarations — so your scheme stays compliant without you touching it.
Key Payroll Deadlines Every Employer Should Know
| Deadline | What's due |
|---|---|
| On or before each payday | FPS submitted to HMRC under RTI |
| 22nd of each month | PAYE and National Insurance paid to HMRC (19th if paying by post) |
| 31 May | P60s given to all employees still employed at 5 April |
| 6 July | P11Ds and P11D(b) filed for benefits in kind (company cars, private medical and similar) |
| 22 July | Class 1A National Insurance on benefits paid to HMRC (19 July by post) |
Miss these and penalties follow automatically. Our payroll calendar tracks every one for every client, so deadlines are met without you needing to remember them.
CIS Payroll for Construction Businesses
If you work in construction, the Construction Industry Scheme (CIS) adds another layer on top of PAYE. Contractors must verify subcontractors with HMRC, deduct 20% (or 30% for unverified subcontractors) from payments, file monthly CIS returns by the 19th of each month, and issue deduction statements to every subcontractor.
We run CIS alongside payroll for contractors across South East London — verification, deductions, monthly returns and statements — and for subcontractors we make sure CIS deductions are properly offset or reclaimed through your accounts or self assessment, where refunds are frequently due.

Frequently Asked Questions
How much do outsourced payroll services cost?
Outsourced payroll is typically charged per employee per pay run, and for a small business usually works out at a modest fixed monthly fee — generally less than the combined cost of payroll software, training and staff time in-house. Bayar Hughes & Co quotes a fixed fee up front based on your number of employees and pay frequency.
What is RTI and when do payroll submissions have to reach HMRC?
RTI (Real Time Information) is the system under which employers report pay and deductions to HMRC. A Full Payment Submission (FPS) must be sent on or before each payday — every pay run, without exception. Late submissions attract HMRC penalties that increase with the size of your workforce.
When do employees need to receive their P60 and P11D?
Employees still employed at 5 April must receive their P60 by 31 May following the end of the tax year. P11Ds, which report benefits in kind such as company cars or private medical insurance, must be filed with HMRC and copies given to employees by 6 July, with the Class 1A National Insurance paid by 22 July.
Do I have to offer a workplace pension to my staff?
Yes. Auto-enrolment applies to every UK employer from the moment they take on their first member of staff. Eligible workers must be enrolled into a qualifying pension scheme, minimum contributions paid, and a declaration of compliance completed with The Pensions Regulator, with re-enrolment duties roughly every three years.
Can you handle CIS payroll for construction contractors?
Yes. We verify subcontractors with HMRC, calculate the correct 20% or 30% CIS deductions, file the monthly CIS return by the 19th, and issue deduction statements to subcontractors. We also help subcontractors reclaim CIS deductions through their accounts or self assessment, where refunds are often due.
