A comprehensive tax planning guide covering investment strategies, deductions, business structuring, and compliance deadlines for FY 2025-26.
Individual Tax Planning Strategies for FY 2025-26
Effective individual tax planning for FY 2025-26 begins with a comprehensive assessment of all eligible deductions available under the old regime. Section 80C permits deductions up to Rs 1.5 lakh for investments in EPF, PPF, ELSS mutual funds, life insurance premiums, NSC, home loan principal repayment, and children's tuition fees. Individuals who are not maximising this deduction should prioritise ELSS (tax-saving mutual funds) for their combination of equity market participation, potential for capital appreciation, and the shortest lock-in period (3 years) among 80C instruments.
Section 80CCD(1B) permits an additional deduction of Rs 50,000 for contributions to the National Pension System (NPS) over and above the Rs 1.5 lakh limit under Section 80C. For individuals in the 30% tax bracket, this translates to a direct tax saving of Rs 15,600 per year (including cess). Health insurance premiums under Section 80D — up to Rs 25,000 for self and family, and an additional Rs 50,000 for premiums paid for senior citizen parents — offer further deduction opportunities that are fully compatible with either a term life or an investment-cum-insurance structure.
Business Tax Planning — Key Strategies
For businesses, tax planning in FY 2025-26 should focus on optimising the timing of revenue and expenses, maximising eligible deductions, and ensuring that all eligible credits are correctly claimed. Under Section 35 and its sub-sections, businesses can claim weighted deductions for scientific research expenditure — 100% for in-house research and 150% for contributions to approved research institutions. The enhanced deduction for expenditure on agricultural extension projects and skill development under Section 35CCC and 35CCD provides additional planning opportunities for eligible businesses.
Business structures should be reviewed annually to ensure they remain optimal from a tax perspective. The choice between a sole proprietorship, partnership, LLP, and private limited company has significant tax implications that evolve as the business grows. For businesses generating consistent profits above Rs 50 lakh, the corporate tax rate of 22% under Section 115BAA (plus effective surcharge and cess of approximately 25.17% effective rate) becomes significantly advantageous compared to the highest individual tax rate of 42.74% (for income above Rs 5 crore). Where business income exceeds this threshold, conversion to a company structure warrants serious evaluation.
Advance Tax and Compliance Calendar
Advance tax payment — mandatory for taxpayers with estimated annual tax liability exceeding Rs 10,000 — must be paid in four instalments: 15% by June 15, 45% by September 15, 75% by December 15, and 100% by March 15 of the assessment year. Failure to pay advance tax results in interest under Sections 234B and 234C at 1% per month of the shortfall. For individuals with variable income — business income, capital gains, or rental income — estimating advance tax liability correctly requires active monitoring of income throughout the year rather than a single year-end estimate.
The income tax return filing deadline for individuals not subject to audit is July 31, while for those subject to audit (business income exceeding Rs 1 crore for non-professionals or Rs 50 lakh for professionals), the deadline is October 31. Late filing attracts a penalty under Section 234F (Rs 5,000 for total income above Rs 5 lakh) and interest under Section 234A (1% per month on tax due). Belated returns for FY 2025-26 can be filed up to December 31, 2026, with the applicable late fee. Revised returns correcting errors can be filed any time before the filing deadline, making it advisable to file an early return and revise if new information surfaces.
