8 advanced tax calculators, one screen
This hub bundles the tools most people struggle to compute by hand — from presumptive income under 44AD/44ADA to Section 234 interest, crypto tax at 31.2%, capital-gains indexation and Form 15G/15H eligibility. Every calculator updates live as you type — no steps, no waiting. All figures are based on ITA 2025 / Finance Act 2025.
Key concepts explained
Presumptive taxation (44AD/44ADA/44AE)
Small businesses declare 8% (cash) / 6% (digital) of turnover as profit; professionals 50% of receipts; goods carriers ₹7,500/vehicle/month. No books needed if limits are met, and advance tax is a single instalment by March 15.
Section 234A / 234B / 234C
234A is 1%/month for late filing (min ₹1,000 if tax unpaid). 234B applies when advance tax is below 90% of liability. 234C penalises deferred quarterly instalments (15/45/75/100%).
Crypto / VDA tax
All virtual digital asset gains are taxed at a flat 30% + 4% cess = 31.2% with no deductions except cost of acquisition (trading only). Losses cannot be set off against any income, and a 1% TDS u/s 194S applies.
Indexation & LTCG
Post-July-2024 you may choose 20% with indexation or 12.5% without on property/land — the calculator computes both and picks the lower tax. Indexed cost = cost × (CII sale ÷ CII purchase).
Section 89(1) relief
Arrears bunched into one year can push you into a higher slab. Section 89 relief = (tax on current year with vs without arrears) − (tax on the arrear year with vs without). Form 10E is mandatory before filing.
Form 15G / 15H
Submit to your bank to stop TDS on interest if your tax is nil. 15H (senior, 60+) needs only that condition; 15G (below 60) also needs interest ≤ the basic exemption.
