Indonesia: Indonesia Explains Child Income Impact on Parents’ Tax Returns

On 17 September 2026, the DJP published a detailed explanation of how a dependent child’s income triggers underpayment in parents’ Annual Tax Returns (SPT) through the Dependent Income (Dampak Usaha Kependudukan – DUK) mechanism. Under Article 8 of the Income Tax Law, a child’s income exceeding the non-taxable threshold (PTKP) must be combined with the parent’s income if the child is not registered as a separate taxpayer. The Coretax system now auto-populates this data from population registry linkages.

Key Takeaways

  • Automatic Data Matching: Coretax cross-references the child’s NPWP and income reports (e.g., from employers or platforms) with the parent’s family card (KK) data to calculate combined taxable income.
  • Separate NPWP Recommended: Children with independent income should obtain their own NPWP to avoid unfavorable progressive tax rates on combined parental income.
  • Correction Window Open: Taxpayers who filed before this integration can submit a correction return (SPT Pembetulan) without penalty until 31 December 2026.
