Tax Planning

Old vs New Regime? Computed Side-by-Side.

Model regime comparisons, optimize deduction strategies, plan capital gains timing, and compute advance tax liability. Grounded in the actual provisions of the IT Act 2025 and the latest Finance Act amendments.

The Problem

The dual-regime system forces CAs to run parallel computations for every client. A salaried individual with HRA, 80C, 80D, home loan interest, and NPS contributions may save more under the old regime, or may not. Getting it wrong means the client either overpays tax or faces scrutiny for an incorrect regime election. Add capital gains from property sales, ESOP exercises, and mutual fund redemptions, and the planning matrix becomes unwieldy without structured computation.

How TaxMarg Helps

Old vs New Regime Comparison

Input the client's income profile and deductions. TaxMarg computes tax liability under both regimes using the actual slab rates, standard deduction (Rs 75,000 under new regime), and applicable surcharge, showing the exact breakeven point where one regime becomes more favorable.

Capital Gains Optimization

Model the tax impact of selling assets at different times. See how holding period affects STCG vs LTCG treatment, whether indexation benefit applies (grandfathered for pre-2025 assets), and how harvesting losses under Section 70/71 can offset gains across asset classes.

Advance Tax & Due Date Planning

Compute quarterly advance tax instalments under Section 210 based on projected income. Get alerts for the 15% / 45% / 75% / 100% quarterly thresholds, interest implications under Sections 234B and 234C for shortfall, and the Section 207 exemption for senior citizens without business income.
