Contract reference

F&O lot sizes, with the date NSE published them

The current market lot for all 213 F&O underlyings, taken from NSE's own market-lots file and shown with that file's date — plus how quantity on any of these contracts becomes turnover in your ITR-3.

Scope: ITR FNO produces automated, source-linked workpapers for CA review. It is not an e-filing service, legal opinion, tax audit, or substitute for your chartered accountant. Your CA decides the tax position and files the return.

Why the date matters more than the number

NSE has revised F&O lot sizes three times in roughly fifteen months. Most reference tables on the web carry no date at all, and several are two revisions behind — which is worse than useless, because a wrong multiplier silently misstates every position size and every notional figure computed from it. Every figure on these pages carries the source file it came from and the date that file was published.

Source: NSE market lots file, dated by NSE. Last verified by this site . NSE lot sizes as published on 2026-07-31; last checked against NSE on 2026-08-02. Lot sizes are contract specifications and are revised periodically; check the source file before relying on a figure for a position you are about to take.

How quantity on this contract becomes ITR-3 turnover

Turnover is not what you traded — it is what settled. Ten lots of NIFTY at 65 units each is 650 units of exposure on the AUG-26 contract, and none of that number appears anywhere in your return. What enters turnover is the outcome of each settled position.

The rule that governs: ICAI GN 2022/2023 para 5.10b — absolute profit/loss, sale premium not added

The result is a figure that is normally far below the notional value of the contracts and far above net profit. It feeds the F&O turnover field in Part A - Trading Account of ITR-3 for AY 2026-27, and it is the input to the section 44AB threshold test.

The formula half the internet still teaches is superseded

You will find the formula “absolute profit plus premium received on options sold” repeated widely, including by sources that have not been updated in years. It no longer governs. The 2022 revision removed premium received on sale of options from F&O turnover. Turnover is now the sum of absolute favourable and unfavourable differences alone.

Superseded: Pre-2022 ICAI Guidance Note — absolute profit/loss PLUS premium received on sale of options. SUPERSEDED; do not file on this figure.
Authority: ICAI Guidance Note on Tax Audit under section 44AB of the Income-tax Act, 1961, 8th edition (2022), para 5.10 — as carried into the 2023 revision, effective .

The difference is not academic. For an option writer the older formula can add the entire premium received to turnover, pushing a book that sits below the section 44AB threshold on the current rule above it — and a tax audit obligation that does not exist is an expensive answer to get wrong in either direction. Which threshold applies also depends on the 5% cash receipts and payments test and on presumptive-tax history, so turnover alone does not settle it.
