Important Warnings

  • All individual jobs are below the £2,373/month threshold, but combined income exceeds the annual threshold
  • This creates a significant underpayment that PAYE cannot collect
  • Significant underpayment of £1,542 per year
  • Multiple employers cannot see your total income - each applies thresholds separately

Recommendations

  • You will likely need to complete Self Assessment to pay the balancing amount
  • Budget £128 per month for the student loan underpayment
  • Consider making voluntary payments to SLC to avoid a large bill via Self Assessment

How PAYE Works with Multiple Jobs

Same Employer

  • • Income from multiple jobs combined
  • • Thresholds applied to total income
  • • Deductions allocated proportionally
  • • Generally captures correct amount

Different Employers

  • • Each employer operates independently
  • • Thresholds applied separately to each job
  • • No communication between employers
  • • Can create significant underpayments

Understanding PAYE with Multiple Jobs

The PAYE Problem

  • • Each employer only sees their own payments to you
  • • Thresholds applied separately to each job
  • • Multiple jobs below threshold = £0 deductions
  • • But combined income may exceed threshold
  • • Creates underpayment that PAYE cannot collect

Self Assessment Solution

  • • Self Assessment sees total income from all sources
  • • Calculates true liability on combined income
  • • Deducts PAYE repayments already made
  • • Balancing payment due by 31 January
  • • Can be substantial for multiple job holders

Example Scenarios

Two £2,000/month jobs (Plan 2):

• Each job: Below £2,373 threshold → £0 PAYE deductions

• Combined: £4,000/month → True liability: £146/month

• Result: £1,752 annual underpayment via Self Assessment

One job above, one below threshold:

• Job 1: £2,500/month → £11.43 PAYE deduction

• Job 2: £1,800/month → £0 PAYE deduction

• Combined creates additional liability not captured by PAYE

Multiple Jobs Creating Student Loan Issues?

PAYE can't always capture the correct student loan repayments across multiple jobs. Understanding this gap is crucial for avoiding unexpected bills.
