In most cases, TDS will have been already deducted against your salary income. Therefore, the need to check the advance tax liability does not arise. However, if you are switching jobs during the year, it is necessary to provide the income details of the previous job to the current employer. If not, exemptions and deductions may be considered twice, resulting in short TDS deduction. In those cases, you need to pay advance tax.
Advance Tax on Capital Gains From Shares, Mutual Funds and Property
Advance tax liability for capital gains arise from the quarter in which the transaction takes place. For example, if you have sold a building in the month of November, you need to pay 75% of the total tax liability as advance tax in the third quarter (within 15th December). There is no need to pay advance tax in the preceding quarters as the income itself has not arisen for those quarters. TDS deducted against sale consideration, if any, need to be considered for advance tax calculations.
Advance Tax for Business Owners, Freelancers and Professionals
Advance tax liability for freelance and business income depends on whether TDS is already deducted against the business income or not. Please check if TDS is already deducted against your freelance and professional income. If already deducted, it also needs to be considered for tax calculation. If the tax liability after reducing the TDS falls within ₹ 10,000, advance tax liability does not arise.
Advance Tax Exemption for Senior Citizens
Resident senior citizens who do not have business income do not have to pay advance tax even if your estimated tax liability goes beyond ₹10,000.
