Estimate capital gains tax on the sale of land or a building under the current Indian rules — the post-23 July 2024 choice between 12.5% and 20% with indexation, per-year indexed improvements, and Section 54 / 54F / 54EC reinvestment relief.
Purchase
Improvements (optional)
Add any capital improvements (renovation, an added floor, etc.) with the year each was done — each is indexed from its own year.
Sale
Reinvestment relief (optional, long-term only)
Long-term gains can be sheltered by reinvesting — in a new house (Sec 54 for a house sold, or Sec 54F for land/other) and/or in 54EC capital-gains bonds. Leave at 0 if not claiming.
