Cost price is the statutory acquisition base.
Cost price is the statutory acquisition base. Fair market value replaces or informs it only where a specific rule permits—such as eligible assets held before 1 April 2001—or where valuation provisions require FMV. A current broker estimate cannot simply replace a low historical cost.
The phrase fair market value vs cost price property compresses several legal questions into one line. The outcome cannot be trusted until the page identifies the relevant person, transaction, period, source document and statutory exception. A high-quality calculator should therefore show why an amount was accepted or rejected instead of displaying a black-box answer.
Capital gains use actual/previous-owner cost, statutory deemed cost and eligible FMV substitution. Sale consideration has a separate stamp-duty-value rule. Gift taxation, business conversion and related-party transactions can invoke different FMV mechanisms.
Tax Year 2026–27 means income earned from 1 April 2026 under the Income-tax Act, 2025. AY 2026–27 relates to FY 2025–26 and remains under the Income-tax Act, 1961.
| Check | What to verify |
|---|---|
| Classification | Asset/income type, holding period and special provision |
| Computation base | Gross consideration/income less only permitted items |
| Adjustment | Eligible loss, threshold, exemption or deduction |
| Tax | Applicable normal/special rate, surcharge and 4% cess |
| Credit | TDS/TCS/advance tax adjusted after gross liability |
A property bought in 1995 for ₹6 lakh has eligible FMV of ₹24 lakh on 1 April 2001. The seller may use the permitted 2001 value under the cost rule, but cannot use a 2026 market value of ₹1.5 crore as acquisition cost.
The example is intentionally presented as a calculation trail. The final result must be recomputed when a date, residence test, holding period, asset classification, employee category, notification, treaty or source document changes.
Capital-gain pages often begin with a percentage and therefore miss the decisive work: identifying the asset, statutory acquisition date, transfer event, cost rule, holding period and special deeming provision. A 12.5%, 20% or 30% rate is meaningful only after the gain has been correctly characterised. TDS or STT does not perform that classification.
The computation should retain each acquisition lot, corporate action, cost adjustment, transfer expense, loss set-off and exemption allocation. Aggregation should occur only after character and rate are determined. This matters where a single financial year contains equity STCG, equity LTCG, property gain, VDA transactions and brought-forward losses, each with a different tax treatment.
The Finin2min calculator linked below should retain the user's original input, display the legally accepted amount, identify the formula and rate, and state the reason for every cap or rejection. Rate-sensitive output should show the applicable tax year or effective date. Where facts cannot be automated—such as treaty PE, beneficial ownership, continuity of service or property valuation—the tool should flag professional review rather than make an unsupported assumption.
Generic pages also tend to mix a tax credit with a deduction, a labour entitlement with an income-tax exemption, or a supply value with business income. That can produce a mathematically neat but legally wrong result.
