/ The schedule + percentages
Four instalments.
FY 2026-27 advance tax instalments:
| Instalment | Due date | Cumulative % of annual tax |
|---|---|---|
| Q1 | 15 June 2026 | 15% |
| Q2 | 15 September 2026 | 45% |
| Q3 (THIS) | 15 December 2026 | 75% |
| Q4 | 15 March 2027 | 100% |
Who must pay advance tax:
- Any taxpayer with tax liability (after TDS/TCS credit) > INR 10,000 in the FY.
- Individuals, HUFs, firms, LLPs, companies - all applicable.
- Section 44AA presumptive income scheme: specific rules apply (see below).
- Senior citizens (60+ years) without business income are exempt from advance tax if their income is only from pension / interest / rent.
/ How to compute Q3 payment
The math.
- Estimate FY 2026-27 total income: salary + business + capital gain + other sources + any adjustments.
- Compute estimated tax liability: at applicable slab rate (new regime default) + surcharge + cess + specific-section tax (115BBH VDA, 112A LTCG, 111A STCG, 115BAC concessional).
- Reduce TDS / TCS already deducted: Form 26AS + AIS verification.
- Net advance tax liability: estimated tax - TDS/TCS - any Section 90/91 Foreign Tax Credit.
- Q3 cumulative requirement: 75% of net advance tax liability.
- Q3 payment due: Q3 cumulative requirement - advance tax already paid in Q1 (15%) + Q2 (45% = 30% incremental).
Payment method: Challan ITNS 280, Code 100 (Advance Tax). Via online banking, debit card, UPI, net banking, or at designated bank branches. Keep Challan Identification Number (CIN) for reconciliation.
/ Interest for non-compliance
Section 234B + 234C.
Section 234B (Interest for default in payment of advance tax):
- If taxpayer has not paid at least 90% of total assessed tax (after TDS) as advance tax, 1% per month simple interest from April 1 to date of regular assessment.
Section 234C (Interest for deferment of advance tax):
- If 15% of advance tax not paid by 15 June: 1% per month for 3 months on shortfall.
- If 45% not paid by 15 September: 1% per month for 3 months on shortfall.
- If 75% not paid by 15 December: 1% per month for 3 months on shortfall.
- If 100% not paid by 15 March: 1% per month for 1 month on shortfall.
Combined, missing Q3 can cost 3-4% effective annual interest on the shortfall. For large advance tax liabilities (INR crore+), interest costs are material.
/ Section 44AA / 44ADA / 44AD exceptions
Presumptive scheme rules.
- Section 44AD (small business): presumptive 8% / 6% deemed profit. Advance tax: can be paid in SINGLE instalment on 15 March of FY. No Q1 / Q2 / Q3 obligation.
- Section 44ADA (specified professionals): presumptive 50% deemed profit on gross receipts up to INR 75 lakh (95%+ digital receipts). Same single-instalment relief: pay by 15 March. See freelancer tax.
- Section 44BB / 44BBB (specific sectors): oil + gas, non-resident shipping. Specific rules.
- Section 44ABB: hotels + restaurants. Specific rules.
If presumptive-scheme taxpayer OPTS OUT, standard four-instalment advance tax applies.
/ Common Q3 December mistakes
What to avoid.
- Under-estimating full-year income: year-end bonus / Diwali bonus / capital gain / rental income not reflected. Q3 payment inadequate → Section 234C interest.
- Missing TDS reconciliation: TDS reflected in Form 26AS but not in advance tax computation. Over-payment.
- Capital gain omission: realised in October / November but Q3 payment doesn't reflect. Section 234C interest.
- Section 115BBH (crypto) + Section 112A (equity LTCG) at specific rates not applied: 30% VDA + 12.5% LTCG not at slab.
- Foreign income taxable (resident status): foreign dividend / rental / capital gain not included. Especially relevant for NRIs who became residents during FY.
- Wrong Challan Code: Code 100 is Advance Tax; Code 300 is Self-Assessment Tax. Using wrong code causes credit mismatch.
- Missing CIN reconciliation: Challan Identification Number not reflected in Form 26AS. Follow-up with bank + CBDT for correction.
