Tax
Indian income tax has two parallel regimes since FY23-24. The new regime has lower rates but very few deductions; the old regime has higher rates but lets you carve out HRA, Section 80C, 80D, home-loan interest under Section 24, and so on. For roughly half the salaried population the new regime wins by default; for the other half — typically those with home loans, rent payments, and full 80C utilization — the old regime still comes out ahead. These calculators help you check which side you land on without doing the math by hand.

Old vs new regime — when each wins
The new regime is simpler: standard deduction of ₹75,000, lower slabs, and almost no other carve-outs. It wins when you don't have a home loan, don't pay rent (own your home), and don't max out 80C beyond EPF. The old regime wins when you stack: HRA + Section 24 home-loan interest + full 80C (EPF + PPF + ELSS or tax-saver FD) + 80D health insurance. The income-tax FY26 calculator on this page (when live) computes both sides for your inputs and shows the delta.
HRA — claimed wrong by most renters
HRA exemption is the minimum of three values: (1) actual HRA received from the employer, (2) 50% of basic salary in metro cities (40% non-metro), (3) actual rent paid minus 10% of basic. Most renters either claim the HRA on their salary slip blindly (over-claim) or skip it because the math feels intimidating (under-claim). The HRA calculator does the three-way min calculation for you. The receipt requirement: PAN of landlord is mandatory if annual rent exceeds ₹1 lakh.
Capital gains on equity, debt, real estate
Post 23-July-2024 budget rules: equity LTCG (>1 year holding) at 12.5% above ₹1.25 lakh per financial year. Equity STCG (≤1 year) at 20%. Debt MFs bought after 1-April-2023 at slab rate regardless of holding period (Section 50AA, no indexation). Property LTCG at 12.5% without indexation OR 20% with indexation, taxpayer's choice for properties acquired before 23-July-2024. The capital gains calculator (when live) handles all four cases.
GST is its own thing
GST is a consumption tax, not income tax. The GST calculator is meant for small-business owners and freelancers who need to add or extract GST on an invoice line. Standard rates are 5%, 12%, 18% and 28%. Reverse calculation (working out the base amount from a GST-inclusive total) is the most common use.
