This is a 7-tab income tax reference and planning tool for AY 2026-27 (FY 2025-26). It calculates your tax under both Old and New Regimes, estimates advance tax instalments and interest, provides ready-made tax tables and slab charts, lists all key deductions and ITR filing deadlines — all in one offline file. Nothing you type is sent or stored anywhere.

Use the tab bar at the top to navigate. Each tab is independent — you can use any tab without filling in the Calculator first, except the Advance Tax tab which auto-pulls your tax figure from the Calculator.

The main tax computation screen. Follow these steps:

1. STEP 1Enter your name and PAN (optional — used only on the printout) and select your age category: Below 60, Senior Citizen (60–79), or Super Senior Citizen (80+). Age affects the Old Regime basic exemption limit.
2. STEP 2Enter your income in the grey input cells: Gross Salary, Rent Income, Interest on housing loans (let-out and self-occupied), Business/Profession income, Other Income, Short Term Capital Gain u/s 111A and Long Term Capital Gain u/s 112A. Enter 0 for any item that does not apply — never leave a cell blank.
   Colour cues on each input cell: Green strip = valid amount entered; Amber strip = still zero (you may have missed it); Red strip = amount exceeds the legal cap (the cap actually applied is shown below the cell).
3. STEP 3Enter deductions: S. 80C (max ₹1,50,000 auto-applied), S. 80CCD(2) (employer NPS), S. 80D (mediclaim) and Other Deductions. Under the New Regime only S. 80CCD(2) is permitted — the tool applies this rule automatically.
4. STEP 4Read the result: tax under both regimes appears instantly with the beneficial regime highlighted. Detailed slab-wise working is shown for verification.
5. STEP 5Export your computation:
   • 🖨️ Print / PDF — opens the browser print dialog with a formal 2-page computation sheet (Page 1: Income & Deductions; Page 2: Tax Calculation + Verdict).
   • 📄 Save to PDF — directly downloads the calculator screen as <Name>_Tax_Computation_AY2026-27.pdf.
   • 🖼️ Save to JPEG — downloads the same view as a high-resolution image, ideal for WhatsApp or social media.
   • 🔄 Reset — clears all inputs to zero.  |  🌙 Dark — toggles dark mode.

Below the calculator — Insights panel:

• 📊 Comparison chart: Old vs New Regime side-by-side with Gross Income, Deductions, Taxable Income, Tax and Effective Rate. The 3D bar chart shows the cheaper regime in green with exact savings.
• ⚠️ ₹12 lakh alert: If New Regime taxable income is just above ₹12,00,000, a yellow marginal-relief box appears. If the rebate covers your full tax, a green confirmation box appears.
• 💬 WhatsApp / 📷 Image / 📋 Copy: Share your regime comparison instantly. Your name and PAN are never included in shared content — they appear only on your own printout.

Calculates your advance tax instalments and estimates interest u/s 234B and 234C for FY 2025-26. Advance tax (S. 207) is payable if total tax liability exceeds ₹10,000 after TDS.

1. STEP 1Select regime (New or Old) — the Total Tax Liability auto-populates from the Calculator tab. You can override it if your estimate differs.
2. STEP 2Enter TDS/TCS expected for the full year. The Net Tax Payable (for advance tax) is computed automatically.
3. STEP 3Enter the Date of Assessment (the date up to which S. 234B interest is to be estimated — typically 31 Jul of the AY or the date of filing).
4. STEP 4Enter amounts already paid against each of the four instalment due dates (15 Jun, 15 Sep, 15 Dec, 15 Mar). Each instalment row shows a ✅ badge if you paid enough or a ⚠️ badge if short.
5. STEP 5Read the interest estimates: S. 234C (deferment of instalments) and S. 234B (overall shortfall) are shown separately with month-wise workings.
