What this tool does

Reconcile post-1 October 2024 buyback proceeds, deemed-dividend amount, acquisition-cost capital loss and illustrative set-off buckets.

The shareholder-side buyback tax framework changed materially from 1 October 2024. The calculator therefore does not use the older company-level buyback-tax model.

The page separates two streams that users often incorrectly net together: the buyback amount treated through the dividend framework and the tax cost basis (plus any allowable section 48 transfer expenditure entered) that can create a capital loss under section 46A mechanics.

The entered “effective dividend rate” is deliberately user-controlled because final tax depends on total income, residency, surcharge, cess and other facts. This tool does not pretend one rate fits every shareholder.

Loss set-off is shown as a reconciliation aid: short-term capital loss can be modelled against entered short- and long-term gains, while long-term capital loss is restricted to the entered long-term-gain bucket. Final return reporting should be reconciled with the applicable ITR schedule.

Calculation methodology

Deemed dividend = buyback consideration; capital-loss bridge = entered tax cost basis + entered allowable transfer expenditure because section 46A treats the buy-back consideration as nil for this capital-gains computation under the post-1 October 2024 framework.

The engine validates required values before calculating and rejects impossible combinations instead of converting them to zero silently. Dates, thresholds and category switches that drive the result remain visible to the user.

Applicable rule and legal basis

The logic on this page is built from the instrument(s) below. Where a rule did not clearly cover a scenario, that scenario is excluded rather than estimated.

Reading and interpreting the result

1. Confirm the classification

The most common error in regulated calculations is not arithmetic; it is putting the facts into the wrong legal or product category. Check the transaction, entity, holding, policy or taxpayer classification before relying on the number.

2. Preserve the evidence trail

Keep statements, acknowledgements, invoices, policy schedules, complaint IDs, tax workings or orders that support the inputs. A number without an evidence trail is difficult to defend in a complaint, return, claim or review.

3. Re-check the effective date

Rules can change. This page records a source-check date, not a fabricated professional review date. If the event belongs to an older period, confirm that the rule version used here applies to that period.

Frequently asked questions

Why is the buyback amount not treated as normal sale consideration?

For the post-1 October 2024 framework, the buyback amount is brought into the deemed-dividend framework and section 46A mechanics treat consideration as nil for the capital-gain computation.

Can I simply subtract the capital loss from dividend income?

No. Dividend income and capital-loss set-off operate in different heads/rules.

Why do I enter an effective dividend tax rate?

Because the shareholder’s final tax rate is personal and can depend on many facts.

Can a long-term capital loss reduce STCG?

The tool does not allow that; the illustrative LTCL bucket is applied only against LTCG.

Is the tool sufficient for filing the ITR?

It is a reconciliation aid. Match the output to the current ITR schedules and your complete income/loss position.

Methodology, assumptions and sources

Scope: Computes interest on delayed GST tax payment under Section 50 of the CGST Act.

Calculation logic

  1. Interest = Tax amount paid late × 18% per annum (or 24% per annum for the specific case of ITC wrongly availed and utilised, per the proviso) × (Number of days delayed ÷ 365).
  2. Interest is computed on the net tax liability payable via the electronic cash ledger (after ITC set-off), consistent with the current interpretation of Section 50(1) as clarified by CBIC circular, from the day after the due date until the date of actual payment.
  3. Where the case involves wrongly availed and utilised ITC, apply the higher 24% rate specifically to that portion, per Section 50(3), while the remaining (non-ITC-related) shortfall continues at 18%.
