Payroll tax is one of the most complex and high-stakes areas of business compliance. Getting it wrong can result in significant penalties, unhappy employees and problems with your tax authority. Whether you are managing PAYE in the UK, PAYG withholding in Australia, source deductions in Canada or federal/state payroll taxes in the US, the fundamentals are the same: calculate correctly, withhold accurately and remit on time.
Register as an employer with your tax authority
Set up your payroll system with correct tax tables and rates
Calculate gross pay, deductions and net pay for each pay period
Withhold the correct amount of income tax from employee wages
Calculate and remit employer contributions (superannuation, national insurance, etc.)
Issue payslips to employees showing all deductions
Remit withheld amounts to the tax authority by the due date
File annual or periodic payroll reports as required
Businesses in Australia operating under the GST + BAS system must meet these compliance requirements set by ATO:
Using outdated tax tables or rates
Not accounting for tax-free thresholds correctly
Missing employer contribution obligations (super, national insurance, etc.)
Not issuing payment summaries or tax certificates to employees on time
Confusing contractor payments with employee payroll
Not reconciling payroll records with bank payments regularly

This depends on your country. In Australia: PAYG withholding + superannuation guarantee. In the UK: PAYE income tax + National Insurance. In the US: Federal income tax + Social Security + Medicare + state taxes. In Canada: CPP + EI + income tax. SortBooks helps track all payroll-related expenses.
Remittance frequency depends on your country and the size of your payroll. Most small businesses remit monthly or quarterly. Larger employers may need to remit more frequently.
While SortBooks does not process payroll directly, it automatically categorises payroll transactions in Xero - separating gross pay, tax withholdings, superannuation/pension contributions and net pay. This ensures your financial statements and tax reports are always accurate.
