Advance Tax for Salaried Employees with Other Income: Due Dates, Calculation & Section 234C
"Advance tax" sounds like something only businesses pay — but the moment a salaried employee earns rental income, sells shares for a gain, or freelances on the side, advance tax obligations can apply too. Missing them brings monthly interest under Sections 234B and 234C.
When Does Advance Tax Apply to a Salaried Person?
Under Section 208, advance tax must be paid if your total tax liability for the year, after reducing TDS already deducted, is ₹10,000 or more. For most salaried employees with only salary income, employer TDS covers this entirely. But the following additional income streams often aren't fully covered by TDS:
For the connected rule or filing step, see Advance Tax Interest Calculator — 234B and 234C.
- Capital gains from selling shares, mutual funds, or property — no TDS is deducted on capital gains for resident individuals
- Rental income — TDS under Section 194-IB applies only if the tenant is an individual/HUF paying rent above ₹50,000/month, and even then often isn't deducted correctly
- Interest income — banks deduct TDS at 10% (Section 194A), but if you're in the 20% or 30% slab, there's a shortfall
- Freelance/consulting income — clients deduct TDS at 10% under Section 194J, again often less than your marginal rate
- Dividend income above ₹5,000 — TDS at 10%, may be insufficient for higher-slab taxpayers
Quarterly Due Dates & Instalment Percentages
| Due Date | Cumulative % of Estimated Annual Tax |
|---|---|
| On or before 15 June | 15% |
| On or before 15 September | 45% |
| On or before 15 December | 75% |
| On or before 15 March | 100% |
"Cumulative" means the 45% due by September includes the 15% already paid in June — you're paying an additional 30% in the September instalment, not a fresh 45%.
Worked Example: Salaried Employee with Capital Gains
Suppose your salary TDS fully covers the tax on your salary income, but you sold equity shares in August realising a long-term capital gain on which the tax (after the Section 112A exemption) works out to ₹40,000.
| Instalment | Cumulative Requirement | Note |
|---|---|---|
| 15 June | ₹6,000 (15% of ₹40,000) | Gain arose in August — no 234C interest for this instalment if the tax is paid by the next due date |
| 15 September | ₹18,000 (45%) | Pay the full ₹18,000 now, since the gain has already arisen by this date |
| 15 December | ₹30,000 (75%) | Pay the incremental ₹12,000 |
| 15 March | ₹40,000 (100%) | Pay the final ₹10,000 |
The "unforeseen income" exemption under Section 234C means capital gains, lottery winnings, or other income that genuinely could not have been anticipated do not attract interest for instalments due before the income arose — provided the proportionate tax is paid by the immediately following instalment.
Section 234B vs Section 234C: What's the Difference?
| Section | Triggers When | Interest |
|---|---|---|
| 234B | Total advance tax paid by 31 March is less than 90% of the assessed tax | 1% per month (or part) from 1 April until the tax is paid, on the shortfall vs. assessed tax |
| 234C | Any quarterly instalment falls short of the required cumulative percentage | 1% per month for 3 months (1 month for the March instalment) on the shortfall for that instalment |
234B is about the overall annual shortfall; 234C is about the timing of payments through the year. It's possible to pay 100% of your tax by 15 March (avoiding 234B) but still owe 234C interest for earlier quarters where you under-paid relative to the cumulative schedule.
How to Pay Advance Tax
Advance tax is paid using Challan 280 on the income tax e-filing portal, selecting "Advance Tax (100)" as the payment type. Keep the BSR code, challan serial number, and date — these are entered in the "Taxes Paid" schedule of your ITR. Pre-filled data in your Form 26AS / AIS will also reflect these payments after a short lag.
Advance tax — 2026 boundary cases
2026 Act transition: FY 2025–26 / AY 2026–27 remains governed by the Income-tax Act, 1961. Tax year 2026–27 beginning 1 April 2026 is governed by the Income-tax Act, 2025. Use the section/form belonging to the year being computed; do not mix old-Act section numbers into a post-1-April-2026 transaction.
AY 2026–27 control: advance tax is generally triggered when estimated tax payable for the year is ₹10,000 or more after relevant credits. A resident senior citizen (60+) with no income from business or profession is not liable to advance tax under the legacy framework.
| Due date | Cumulative target — ordinary taxpayer |
|---|---|
| 15 June | 15% |
| 15 September | 45% |
| 15 December | 75% |
| 15 March | 100% |
Capital-gain / unexpected-income edge case: section 234C contains relief mechanics where specified income could not be estimated by an earlier instalment and the attributable tax is paid in the remaining instalment(s). Do not mechanically charge three months of 234C interest without testing this exception.
Salary control: compare employer TDS against total estimated tax including interest, rent, capital gains and side income. “TDS deducted from salary” does not mean advance tax can never arise.
