Common Pitfalls to Avoid

Documentation Failures

  • Missing time records: Track staff hours allocated to qualifying activities
  • Incomplete invoices: Ensure all invoices clearly state the qualifying activity

Eligibility Mistakes

  • Double-claiming: Do not claim same expenses under EIS and other schemes (e.g., EDG, PIC)
  • Non-qualifying training: Ensure courses are SSG-funded or Skills Framework aligned
  • Overseas R&D: Only R&D conducted in Singapore qualifies

Timing Errors

  • Late filing: Submit by November 30 of the relevant YA
  • Wrong YA: Match expenses to the correct Year of Assessment
  • IP disposal: Selling IP within one year triggers claw-back

Cash Payout Limitations

  • Exceeding cap: Cash payout limited to S$100K expenses (S$20K cash) per YA
  • Partial election: You cannot change your election after filing
