What does a payroll bureau do?
A payroll bureau processes pay for employers under an agreed service scope. It can calculate wages and deductions, produce payslips, prepare reports and submit payroll information to HMRC. Your business supplies accurate instructions, approves the results and pays employees. You remain legally responsible for PAYE even when processing is outsourced.

What is the bureau’s role?
A payroll bureau is an external service that processes payroll for other businesses. Its role is to turn approved employee and pay information into calculations, documents and agreed submissions. It does not become the employer, decide what someone should earn or remove the need for your own checks.
The service can be narrow or extensive. One agreement may cover calculations and payslips; another may include pension administration, HMRC queries and management reports. The label alone tells you little. Ask for a written schedule of included tasks, exclusions, deadlines and responsibilities before assuming that a particular activity is covered.
What information does a bureau need?
Each run starts with information from your business: salaries, approved hours, overtime, bonuses, absences, starters, leavers and relevant deductions. A useful bureau provides a consistent input format and deadline. It should query missing or contradictory information rather than guessing an employee's hours or final-pay entitlement.
Give one authorised person responsibility for submitting approved changes, with a deputy for absence. Send sensitive information through the agreed secure channel rather than ordinary email attachments. Verify requests to change bank details independently. Even a technically accurate calculation will be wrong if the instructions identify the wrong person, period or rate.
How does it turn instructions into pay?
The bureau calculates gross pay, applicable PAYE deductions, employee National Insurance and other relevant deductions. It also calculates employer National Insurance and pension contributions within the agreed scope. Statutory payments require the correct facts and eligibility information; supplying an absence date alone may not be enough.
Before finalisation, you should receive reports that let you check employee-level results and overall costs. Compare starters, leavers, large movements and unexpected deductions with your instructions. Employer costs are not the same as net wages. Use current official rates and thresholds when checking figures, because tax-year changes can make older examples misleading.
Which documents and submissions are produced?
After approval, the bureau issues payslips through the agreed process and completes the reporting covered by the service. A Full Payment Submission normally reports pay and deductions to HMRC on or before payday, subject to specific exceptions. An Employer Payment Summary is used in relevant circumstances, including reporting certain reductions or a tax month with no employee payments.
The bureau may also prepare P45s for leavers and P60s for eligible employees, alongside year-end payroll work. Confirm who monitors submission acknowledgements and handles rejected reports. Receiving a draft report is not evidence that HMRC accepted a submission. Ask how completed filings and outstanding actions are recorded and communicated.
Who pays employees and pension contributions?
In our service model, we supply a payment file and your business pays employees. You retain control of your bank account, upload the file where appropriate and authorise payment. Check bank processing deadlines as well as payroll deadlines; a completed calculation does not move money into employees' accounts.
Pension support can include worker assessment, contribution calculations and uploading contribution information. Employee communications, opt-outs, re-enrolment and the declaration of compliance need explicit ownership. The Pensions Regulator states that legal responsibility remains with the employer when duties are delegated. Agree who checks successful submissions and who arranges contribution payments.
How does the bureau take over an existing payroll?
Our typical SME switch takes two to four weeks, subject to the condition of records and the complexity of the payroll. We identify missing information, agree the first live payday and arrange HMRC authorisation through Form 64-8. Current official guidance explains the available agent-authorisation processes.
A sound handover includes employee data, tax codes, pension settings and year-to-date totals. Require checks and a parallel run against the outgoing system before approval. Confirm which party sends each live submission. Keep old records accessible until the transfer has been reconciled and retention responsibilities are clear.
What is outside routine payroll processing?
Payroll processing does not automatically include employment-law advice, personal tax planning, benefits reporting or resolving historical errors. Nor should you assume the bureau decides whether a disputed deduction is lawful. Identify specialist questions early and agree whether separate advice or additional work is needed.
Ask for a named specialist and cover contact, supported by escalation arrangements. Streamlining Payroll uses UK-only processing, encrypted payslip portals and role-based access. Agree processing terms and the records you need to retain. Good service means clear responsibilities and traceable decisions, not simply a promise that payroll will be taken off your hands.

Frequently asked questions
Does a payroll bureau pay our employees?
Streamlining Payroll does not pay employees directly. We supply a payment file and supporting reports; your business arranges and authorises employee payments through its bank. Confirm the file format, approval process and banking deadline during setup.
Can the bureau speak to HMRC for us?
We handle agreed PAYE matters with appropriate authority in place. Our onboarding includes Form 64-8. Ask which correspondence you must forward promptly and keep control of your own HMRC access.
What happens if we send a late change?
For a late payroll change, contact your named specialist immediately. The response depends on whether payroll has been approved, submitted or paid. Additional processing or a reporting correction may be needed; your written quote confirms the scope and any separate work.
Does using a bureau remove our PAYE responsibility?
Using a payroll bureau does not remove employer PAYE responsibility. GOV.UK states that employers remain legally responsible even when a provider performs PAYE tasks. Keep an internal owner who reviews payroll, monitors deadlines, retains records and checks employee, HMRC and pension payments.
