BSI TaxProfileFactory vs HMRC Basic PAYE Tools

BSI TaxProfileFactory has no write-up on Specifiction yet; its figures are above.

HMRC Basic PAYE Tools is free payroll software for employers with fewer than 10 employees. It calculates employee tax and National Insurance, sends payroll information to HMRC, and supports Full Payment Submissions and Employer Payment Summaries. Employers can add details for up to nine employees and use calculators for statutory sick, maternity, paternity, adoption, shared parental, parental bereavement, and neonatal care pay. The tool can create payslips to save as PDFs, print, or email with employee agreement. It can also be used alongside commercial payroll software for certain National Insurance number checks or Employer Payment Summary submissions. Employers need to register with HMRC and have a PAYE Online login before using it. The software runs on Linux, macOS, and Windows. It does not support pension auto-enrolment or pension contribution calculations, and employers must secure and back up payroll data themselves; HMRC does not keep a copy or recover lost data.
