FY 2018-19 Advance Tax Calculator
Module A: Introduction & Importance of Advance Tax for FY 2018-19
Advance tax is the income tax payable in advance instead of a lump sum payment at year-end. For Financial Year 2018-19 (Assessment Year 2019-20), the Income Tax Department mandated advance tax payments for taxpayers whose estimated tax liability exceeds ₹10,000 in a financial year. This system helps the government maintain a steady cash flow and reduces the burden of year-end tax payments for individuals and businesses.
The importance of advance tax cannot be overstated. Non-payment or underpayment attracts interest under Section 234B and 234C of the Income Tax Act. For FY 2018-19, the interest rates were 1% per month for default in payment of advance tax. Proper calculation and timely payment can save taxpayers from unnecessary penalties and interest charges.

Module G: Interactive FAQ about Advance Tax for FY 2018-19
What happens if I don’t pay advance tax for FY 2018-19?
If you fail to pay advance tax or pay less than 90% of the assessed tax, you’ll be liable to pay interest under Section 234B at 1% per month. Additionally, if you miss any installment or pay less than the required percentage for that quarter, interest under Section 234C will apply at 1% per month for 3 months for each default.
How is advance tax different from self-assessment tax?
Advance tax is paid in installments during the financial year based on estimated income, while self-assessment tax is paid after the financial year ends but before filing the return. Advance tax is mandatory if your liability exceeds ₹10,000, whereas self-assessment tax is paid to cover any shortfall between your advance tax/tds and actual tax liability.
Can I revise my advance tax payments if my income estimates change?
Yes, you can revise your advance tax payments. If your income estimates increase during the year, you should pay the additional tax in the subsequent installments. The tax department only looks at the total advance tax paid by 31st March, not the individual installments (except for interest calculations).
What is the due date for the last installment of advance tax for FY 2018-19?
The due date for the last installment (100% of advance tax) for FY 2018-19 was 15th March 2019. This is the final opportunity to pay any remaining advance tax to avoid interest charges under Section 234B and 234C.
How do I calculate advance tax on capital gains?
For capital gains, you should pay advance tax in the same quarter you earn the gains. Calculate the tax on the capital gains at the applicable rate (15% for short-term, 20% for long-term with indexation), add cess, and include this in your advance tax payment for that quarter. Remember to consider any basic exemption available.
Is advance tax applicable to senior citizens for FY 2018-19?
Senior citizens (aged 60 years or more) are exempt from paying advance tax if they don’t have any income from business or profession. However, if they have business income, they must pay advance tax like any other taxpayer.
What documents should I keep for advance tax payments?
You should maintain the following documents:
- Challan 280 counterfoil (acknowledgment)
- Bank payment receipts
- Income estimation worksheet
- Calculation of tax liability
- Proof of TDS deductions if any
- Form 26AS for verification
