Ask OAKPRISMWhat information is needed to start payroll?
This depends on whether the payroll is new or transferring. It commonly includes employer and PAYE details, employee records, pay arrangements, year-to-date figures, pension information and an agreed payroll calendar. We confirm the exact checklist for your situation.
Can you take over partway through the tax year?
Yes, a mid-year transfer can be planned. Complete and accurate year-to-date values, previous submissions and employee records are especially important so opening data can be reviewed before the first run.
Which payroll frequencies can you support?
Tell us whether you pay weekly, fortnightly, four-weekly, monthly or on another pattern. We will confirm whether the requested timetable and approval deadlines can be supported before engagement.
What is included in CIS administration?
The agreed service can include subcontractor verification, calculation of CIS deductions, monthly return preparation, payment and deduction statements, and record reconciliation. CIS treatment and employment status depend on the actual working circumstances.
How is pricing calculated?
Pricing depends on the number of employees or subcontractors, pay frequency, complexity, reporting needs and the amount of setup or historical review required. Share those details through the enquiry form for a scoped response.
Can I send payroll data through the contact form?
No. Please use the form only for an initial enquiry. Do not include National Insurance numbers, bank details, payslips or other sensitive payroll information. A suitable method of sharing information can be agreed later.
