234B vs 234C Interest - Key Difference
Section 234B - Annual Default
Applies when total advance tax paid during the year is less than 90% of assessed tax liability. Interest is 1% per month from April 1 of the assessment year until the date of actual payment (or date of assessment, whichever is earlier).
Section 234C - Installment Shortfall
Applies when any particular installment is short of the required cumulative percentage. Each shortfall is charged at 1% per month for 3 months (June/September/December) or 1 month (March). These are independent of 234B.
Frequently Asked Questions
Who needs to pay advance tax in FY 2026-27?▾
Any taxpayer whose total tax liability (after TDS) exceeds ₹10,000 in a financial year must pay advance tax. This includes salaried employees with significant non-salary income (interest, rent, capital gains, freelance), self-employed professionals, and businesses.
What are the advance tax installment due dates for FY 2026-27?▾
15 June 2026: 15% of estimated tax liability | 15 September 2026: 45% cumulative | 15 December 2026: 75% cumulative | 15 March 2027: 100% cumulative. Missing these dates triggers Section 234C interest at 1% per month.
Is advance tax applicable for salaried employees?▾
If your entire tax is deducted as TDS by your employer (i.e., tax due after TDS = 0), no advance tax is required. But if you have additional income (rental income, FD interest, capital gains from equity sales, freelance earnings) where total additional tax > ₹10,000, you must pay advance tax.
What interest is charged if I miss the December advance tax installment?▾
Section 234C charges 1% interest per month (3 months) on the shortfall. E.g., if you should have paid ₹75,000 by 15 December but paid only ₹45,000, interest = 1% × ₹30,000 × 3 months = ₹900.
How do I pay advance tax?▾
Through Challan No. 280 on the Income Tax portal (www.incometax.gov.in). Select 'Advance Tax (100)', enter PAN, assessment year, and amount. You can also pay via ThynkTax - it tracks installments and alerts you before due dates.
