Payroll run right, every single payday.

Outsourced Payroll Services for UK Businesses

Payroll involves more than calculating salaries. PAYE, RTI, pension auto-enrolment, payslips and year-end reporting all need to line up every pay period. We manage the process so your employees get paid correctly and your payroll obligations stay on track.

Why Clients Choose Us?

Beyond offering services, we complement your journey with our commitment to Satisfaction

Our Payroll Services

Payroll is the one part of running a business where a small mistake lands directly on someone else's pay packet. Get it wrong once and you don't just have an HMRC problem, you have a team that's stopped trusting the business to pay them correctly.

Most payroll management errors aren't carelessness, they're software nobody's watching. We run PAYE, RTI submissions, and pension auto-enrolment as an active process through proper managed payroll services, checked against HMRC's deadlines every pay cycle, not a system left to run itself.

We've delivered payroll outsourcing for growing teams since 2008. The businesses that come to us mid-crisis almost always say the same thing, they didn't know auto-enrolment applied from employee one. We make sure you know before it becomes a problem, not after.

    FAQs

    Payroll management is the process of paying employees correctly and on time while meeting PAYE, HMRC, pension, and reporting requirements. It can include calculating deductions, submitting RTI reports, generating payslips, and managing pension auto-enrolment. With Maspartnerpayroll management is handled as part of our outsourced payroll services, so the calculations, filings, and records stay connected. 

    Payroll services can include PAYE registration, payroll software setup, RTI submissions, payslip generation, P11D reporting for benefits in kind, and pension auto-enrolment. The exact requirements depend on your employees and business structure. Maspartner’s outsourced payroll services cover these processes through one managed payroll setup. 

    Yes. You can run payroll yourself even if you have only one employee, but PAYE registration, RTI reporting, and pension auto-enrolment duties may still apply. The number of employees does not remove these responsibilities. For businesses that prefer to keep payroll outside their internal workload, payroll outsourcing provides an alternative. 

    HMRC can charge penalties for late or incorrect payroll reporting, with the amount depending on the type of error and the circumstances. RTI submissions are generally expected on or before the day employees are paid. Using managed payroll services can help businesses keep track of submission dates, payroll records, and reporting requirements. 

    In most cases, yes. Employer’s National Insurance is a separate cost paid by the employer and is not deducted from the employee’s gross salary. It should therefore be included when calculating the overall cost of employing someone. Maspartner includes these calculations as part of its outsourced payroll services. 

    National Minimum Wage rules apply to workers and employees who meet the relevant criteria. Company directors can have different circumstances depending on their role and how they are paid, which is why a director’s salary should be reviewed alongside their wider tax position. This is an area where professional payroll management can help ensure salary payments are handled correctly.

    If an employee meets the eligibility requirements, you may need to automatically enrol them into a workplace pension and meet your duties as an employer. The Pensions Regulator can take enforcement action where an employer does not comply. As part of our payroll servicesMaspartner can help businesses keep payroll and pension requirements aligned when employees join. 

    Yes. Maspartner can take over an existing PAYE scheme during the tax year, review the payroll records and submissions already made, and continue the required reporting. We can also reconcile previous payroll figures so the records remain consistent from the point of transition. This makes payroll outsourcing possible without waiting for the next tax year.
