Key Insights

Multiple Employments: Under PAYE, each employment is treated separately for threshold purposes. Under Self Assessment, all income is aggregated.

Payment Timing: PAYE spreads repayments throughout the year, while Self Assessment requires a lump sum payment on 31 January.

Variable Income: If your income varies significantly within the year, the timing of earnings can affect total repayments under PAYE.

How PAYE vs Self Assessment Affects Student Loan Repayments

PAYE System

  • • Repayments deducted automatically from salary
  • • Each employment treated separately
  • • Threshold applied to each job individually
  • • Payments spread throughout the year
  • • Can result in overpayments with multiple jobs

Self Assessment

  • • Annual calculation based on total income
  • • All income sources aggregated
  • • Single threshold applied to total income
  • • Lump sum payment on 31 January
  • • More accurate for multiple income sources

When Differences Occur

The most significant differences between PAYE and Self Assessment repayments typically occur when you have:

  • • Multiple part-time employments
  • • Combination of employment and self-employment income
  • • Variable income throughout the year
  • • Income from different sources (employment, freelancing, rental income)

If you have multiple income sources that individually fall below the threshold but collectively exceed it, you may pay less under Self Assessment than PAYE.
