Frequently Asked Questions
Which tax regime saves more money in Tax Year 2026-27: New or Old?
For most individuals with income up to ₹15 Lakhs, the New Tax Regime is significantly more beneficial because taxable income up to ₹12 Lakhs is completely tax-free (due to the ₹75,000 standard deduction and Section 87A rebate). The Old Regime is only advantageous if you have very high total deductions (exceeding ₹4.25 Lakhs) across Section 80C (₹1.5L), Section 80D (₹50k), HRA (₹1.5L+), and Home Loan Interest under Section 24(b) (₹2L).
Who is required to pay Advance Tax in India?
Under Section 208 of the Income Tax Act, any taxpayer (individual, freelancer, consultant, business) whose estimated total income tax liability for the financial year after deducting TDS exceeds ₹10,000 must pay advance tax in four quarterly instalments: 15% by June 15, 45% by September 15, 75% by December 15, and 100% by March 15. Senior citizens without business income are exempt.
What are the latest capital gains tax rates on mutual funds and shares?
Under the Finance Act 2024, Long-Term Capital Gains (LTCG) on listed equities and equity mutual funds held for more than 12 months are taxed at 12.5% (without indexation) for gains exceeding the annual exemption limit of ₹1.25 Lakh. Short-Term Capital Gains (STCG) on equity shares held for 12 months or less are taxed at 20%.
What is the difference between GST inclusive and exclusive calculation?
GST Exclusive means adding GST on top of the base price (Base + GST = Final Price). Formula: GST = Base × Rate / 100. GST Inclusive means extracting the embedded GST from a total MRP price. Formula: Base = Inclusive Price × 100 / (100 + Rate), and GST = Inclusive Price − Base.
What happens if I miss the Advance Tax quarterly due dates?
Failure to pay advance tax or deferring quarterly instalments results in mandatory interest penalties: Section 234C charges 1% simple interest per month for quarterly deferment, and Section 234B charges 1% simple interest per month if less than 90% of assessed tax is paid by March 31.
