📌 Key Takeaway: Received an unexpected tax demand order or intimation under Section 143(1)(a)? Learn how to verify challans, file online disagreement, and protect bank accounts from recovery.
Understanding Section 143(1)(a) Intimation & Tax Demands
Upon preliminary automated processing of your filed ITR, CPC Bengaluru generates an Intimation Order under Section 143(1). If CPC's computerized algorithms compute a higher tax liability than what you declared—due to disallowed exemptions, TDS mismatches, or mathematical recalculations—a formal Outstanding Demand Notice is generated under Section 156.
Common Reasons for Sudden Tax Demands
- Uncredited TDS / Advance Tax: Employer or bank failed to deposit TDS under correct PAN, or challan CIN details were mistyped in the return.
- Disallowance of Chapter VI-A Deductions: Claiming deductions in ITR that were not reported in Form 16 issued by employer.
- Interest Levied under Sections 234A, 234B & 234C: Delay in monthly advance tax instalments or filing return after statutory deadline.
- Re-computation under Default New Regime: CPC processing return under New Tax Regime when Form 10-IEA for opting into Old Regime was not filed on time.
