AY 2026-27 discount ITR-3

m.Stock F&O tax filing.

m.Stock F&O traders should treat the broker report as evidence, not as the tax rule itself. m.Stock is a discount-broking brand from Mirae Asset, and active traders often use it for low-brokerage derivatives execution. The correct filing workflow is to export the broker P&L, ledger, and contract notes, then reconcile the numbers to ITR-3, ICAI turnover, and s.44AB audit rules.

m.Stock's tax report is generated through m.Stock Web / m.Stock App. Follow the steps below; this is the canonical source for your ITR-3 filing.

1. Log in to m.Stock Web / m.Stock App
2. Open Reports, Backoffice, Statements, Account, Profile, or Downloads
3. Choose Profit & Loss, Tax P&L, Tradebook, Ledger, or Contract Notes for the relevant financial year
4. Filter for F&O / Equity Derivatives; separately export currency or commodity derivatives if traded
5. Download PDF or Excel files and keep the original broker exports as evidence
6. If m.Stock does not expose a single tax-ready report, combine P&L, tradebook, ledger, and contract notes instead of estimating from dashboard screenshots

Every line in your m.Stock Tax P&L corresponds to a specific ITR-3 schedule or working. Use this table when you (or your CA) transcribe numbers from the broker report into the return.

m.Stock report line	ITR-3 destination	Notes
F&O Realised P&L	ITR-3 Schedule BP	Report as non-speculative business income or loss. Do not move F&O to capital gains merely because shares and derivatives appear in the same broker login.
F&O Turnover	ITR-3 audit-applicability check under s.44AB	Broker turnover is a starting point. Reconcile it against ICAI GN 2025, especially option-sale premium treatment.
Brokerage and statutory charges	ITR-3 Schedule BP (deductible expenses)	For m.Stock, plan fees and flat-brokerage structures can matter as much as per-order brokerage. Brokerage, STT/CTT, exchange charges, SEBI fees, stamp duty, and GST are expenses, not reductions from turnover.
Ledger, fund statement, and reversals	Books reconciliation and audit working papers	Use the ledger to explain actual debits, credits, charge reversals, interest, payout, payin, and account-level costs.
Contract notes and tradebook	Audit trail and turnover reconstruction	Keep trade-level records in case the summary P&L does not explain turnover, charges, or option premium treatment.

Why m.Stock needs a separate evidence trail

m.Stock has its own report layout, login flow, ledger labels, and charge presentation. The tax law is broker-neutral, but the evidence trail is broker-specific. Keep a folder for m.Stock with the FY Tax P&L or P&L statement, full ledger, contract notes, tradebook, and any support tickets or emailed statements used to prepare the return. This lets every ITR-3 number be traced back to a source document.

Reconciling m.Stock P&L with ITR-3

Start with realised F&O P&L, not live portfolio P&L. Then add deductible charges from the ledger and verify whether the broker report already presents net P&L after charges or gross P&L before charges. If the report mixes delivery equity, intraday equity, currency, commodity, or mutual-fund activity with F&O, split them before filing. F&O belongs in Schedule BP; delivery equity usually belongs in capital-gains schedules unless your books treat it as stock-in-trade.

Turnover bridge for m.Stock

The m.Stock turnover field should not be accepted blindly for AY 2026-27. Build a bridge with four columns: broker-reported F&O turnover, realised favourable/unfavourable differences, option-sale premium received, and GN 2025 adjustment if premium is not already netted. Keep this bridge even when audit is not required; it is the working paper that explains why you did or did not cross the s.44AB threshold.

Expense schedule for m.Stock

For m.Stock, plan fees and flat-brokerage structures can matter as much as per-order brokerage. Use the ledger to list brokerage, STT/CTT, exchange charges, SEBI charges, stamp duty, GST, DP/account charges, data costs, software fees, advisory costs, and interest where directly connected to F&O trading. Do not include personal costs or investment-only delivery charges unless there is a clear business nexus. Expenses reduce business profit; they do not reduce turnover.

When m.Stock reports are incomplete

If the broker does not provide a single tax-ready statement, do not estimate from memory or screenshots. Use the best available official exports: tradebook for trade-level result, ledger for charges and cash movements, contract notes for statutory levies, and bank statements only for reconciliation. If a CA prepares or audits the return, give all four files together instead of only the summary P&L.

m.Stock does not publish a crawlable public page that conclusively confirms a GN 2025-compliant F&O turnover method. Treat the broker turnover field as provisional until you verify how options premium is handled in the downloaded report.

See the F&O turnover hub for the full GN 2025 methodology, and use our turnover calculator to cross-check the number in your m.Stock report.

The s.44AB audit test does not vary by broker. It depends on your aggregate F&O business turnover (across all brokers), the 5% cash-receipts/payments rule, and your s.44AD history. A loss alone is not the audit trigger.

Run the audit applicability checker or read the F&O tax audit hub for the full decision tree, including the s.44AD(4) 5-year lock-in trap.

• Same year: F&O loss from m.Stock can offset business income, house property, capital gains, or other sources — not salary.
• Carry forward: 8 assessment years, only against future business income.
• Mandatory: file the loss return on or before the s.139(1) due date. Late = no carry forward.
