Form B1 — Individual income tax return

What this form is for

• Report to the Inland Revenue Authority of Singapore (IRAS) your income for the previous year and claim your reliefs. Form B1 is for tax-resident employees; self-employed people use Form B and non-residents Form M.
• If your employer is in the Auto-Inclusion Scheme (AIS), your employment income is sent to IRAS directly and pre-filled.

Documents to have ready

• Your tax reference number (NRIC or FIN) and your Singpass or Singpass Foreign user Account (SFA)
• Form IR8A from your employer, if it is not in the AIS
• Details of other income (rent and deductible expenses) and of dependants for any new relief claim

Where to send it
