Payroll outsourcing that feels like an extension of your practice
Your clients depend on you to get payroll right, every time. We’re the payroll outsourcing agency that ensures you never let them down.
Why would I outsource payroll services when my team already manages it?
Because for most accountancy firms, payroll isn’t just another compliance task; it’s one of the most high-pressure, time-sensitive, and detail-heavy jobs you handle.
It’s not just about paying people on time. Payroll comes with:
Constantly changing rules
HMRC updates, pension auto-enrolment tweaks, Real Time Information (RTI) requirements, GDPR obligations, the list never ends.
Zero margin for error
Even the smallest mistake can trigger fines, create client headaches, or cause reputational damage.
Fluctuating workloads
Payroll deadlines don’t care if you’re short-staffed or swamped with year-end accounts.
Lack of specialist skills
Not every in-house accountant is a payroll expert, but clients still expect you to “just know” how to handle every scenario.
High admin load
Answering payroll queries, chasing missing timesheets, and keeping up with compliance eats into hours your team could spend on higher-value services.
For many firms, payroll becomes a constant balancing act, keeping clients happy while protecting your team’s time and sanity.

Scope of our payroll outsourcing services
Full payroll processing
We calculate employee wages, process payslips, and handle weekly, fortnightly or monthly payroll cycles accurately and on time.
Real Time Information (RTI) submissions
We submit RTI data directly to HMRC, ensuring full compliance with UK payroll regulations.
Auto-enrolment and pension management
We manage pension contributions, enrolments, and communications in line with The Pensions Regulator's requirements.
Holiday and statutory pay calculations
We ensure your clients’ employees receive accurate SSP, SMP, and holiday pay, calculated according to the latest rules.
HMRC liaison and support
We communicate directly with HMRC on payroll matters, so you don’t have to waste valuable time chasing queries.
Leaver and starter management
We handle new joiner setups, P45/P46 processing, and employee exits with professionalism and speed.
CIS (Construction Industry Scheme)
We handle your CIS compliance by registering you as a contractor and/or subcontractor with HMRC, submitting CIS tax returns on your behalf, and reclaiming any CIS deductions suffered from HMRC.
P11D (Benefit-in-Kind)
We ensure that any benefits provided by the company to directors or employees are accurately reported to HMRC by completing the annual P11D and employer P11D(b) returns. Alternatively, where applicable, we process the benefits through payroll to keep everything fully compliant.
End-of-year processing and P60s
We handle year-end reports, produce P60s, and make sure all deadlines are met without stress.

What our clients say about us
McKenzie Philips Tax Accountants
Kevin Alderton & Team
The contrast with the previous outsourcing company could not have been clearer. Affinity provided us with a dedicated team in the UK and a team leader in India. We have an established system which allows us to prioritise our jobs making sure client satisfaction remains high. We like the ability to switch our usage on and off according to our work volumes and our capacity. Using Affinity Outsourcing has given us a significant competitive advantage and we continue to exploit this and increase our client numbers without compromising service levels.
Artisan Accountants
Using Affinity Outsourcing has changed both my business and my lifestyle. I have an amazing work life balance and knowing that I have a back up plan if there is a reason why I can’t work has helped me enormously. The added value is that I have managed to increase my GRF and therefore the capital value of the business for my retirement without any stress. I cannot recommend this way of working highly enough.
