    YOUR DETAILED SERVICE ROUTE

    Clarity continues beyond the first step.

    The original page-specific roadmap is retained here, with every detail available after the quick enquiry panel.

    Accuracy begins before filing. Return preparation should begin before the statutory deadline. Late records can restrict review time, delay audit coordination and increase the risk of omissions or inconsistent reporting.

    Short answer

    Businesses file ITR-3, ITR-4, ITR-5 or ITR-6 depending on the entity, and the usual due date is 31 July, with 31 October for cases needing a tax audit. For Assessment Year 2026-27, the Income Tax portal lists 21 November 2026 for audit cases, companies and partners of audited firms (CBDT Circular 07/2026), and 30 November 2026 where a transfer pricing report is needed. A late return attracts a late fee under the Income-tax law, and a belated return can be filed later within the permitted time. Confirm the due date for your year on the Income Tax portal.

    Last updated 7 November 2026. Rules, fees and forms change, so confirm the current position on the official portal before you act.

    Identify the filing route before preparing the return.

    Use this table for an initial orientation. The correct route depends on the underlying facts, statutory position and intended use of the output.

    WHAT CHANGES THE SCOPE

    Complexity should be identified before the work begins.

    Volume alone does not determine effort. Entity type, record quality, prior-period gaps and the intended reliance on the output can materially change the engagement.
    01

    Entity and period

    Companies, LLPs, firms, proprietors and NGOs carry different reporting and approval requirements.

    02

    Record readiness

    Structured ledgers and reconciliations require a different effort from incomplete bank, invoice and portal records.

    03

    Transaction complexity

    Multiple states, related parties, imports, exports, payroll and unusual contracts add review points.

    04

    Purpose of output

    Routine filing, audit, funding, banking, board reporting and notice response require different levels of evidence.

    WHY REGISCORP

    We connect books, reconciliations, tax filings, reporting and management decisions instead of treating each output as an isolated task.
    01

    We begin with the entity, transaction volume, filing history and management objective before defining the scope.

    02

    Connected records

    Books, GST, TDS, income tax and corporate filings are reviewed as connected records rather than isolated portal tasks.

    INDICATIVE TIMELINE

    Understand the stages before completion.

    Timing depends on record completeness, transaction volume, clarification speed, management approvals and applicable filing deadlines. The written scope identifies the expected sequence and dependencies.
    1. 01

      Record review

      Usually one to three working days after the core file is received.

    2. 02

      Computation

      Generally three to seven working days for a ready, non-complex file.

    3. 03

      Approval

      Timing depends on clarification and management confirmation.

    4. 04

      Filing

      Completed after approval and required tax payment, subject to portal availability.

    COMMON MISTAKES

    Avoid preventable delays, rework and scope gaps.

    These issues commonly surface after a commercial commitment, deadline or authority query has already created time pressure.
    01

    Starting from AIS alone

    Information statements do not replace complete business books.

    02

    Ignoring GST differences

    Turnover and tax positions should be reconciled where relevant.

    03

    Missing brought-forward items

    Losses, depreciation and credits require prior-year continuity.

    04

    Wrong return form

    Entity and income characteristics determine the appropriate form.

    05

    Unapproved adjustments

    Material tax positions should be understood before filing.

    06

    Waiting until the deadline

    Compressed review leaves less time to correct books or arrange audit information.

    RISK CONTROL

    Financial outputs are only as reliable as the records and representations supporting them.

    Professional preparation and review improve consistency, but cannot replace missing evidence, management judgement, statutory authority decisions or an audit where one is legally required.
    • Credit mismatchUnavailable or mismatched tax credits can change the payable position.
    • Disclosure gapsIncomplete related-party, foreign, asset or statutory information can affect reporting.
    • Late filing consequencesInterest, fees and restrictions depend on the facts and applicable law.
    • Assessment riskFiling does not prevent later verification, notice or assessment by the department.

    Which return applies

    Proprietors usually file ITR-3, or ITR-4 under the presumptive scheme if eligible. Firms and LLPs file ITR-5 and companies file ITR-6.

    If turnover or profit crosses the audit limits, a tax audit report must be filed before the return, and the later audit due date applies.

    What to prepare

    • Financial statements, bank statements and TDS data from Form 26AS and AIS.
    • GST returns that agree with the turnover shown.
    • Details of advance tax paid and loans, assets and liabilities where asked.

    PRACTICAL ANSWERS

    Business ITR Filing frequently asked questions

    These answers are general information. Tax, accounting and filing treatment depends on the entity, period, transaction facts, records and law in force.Ask an expert question
    01Which ITR applies to my business?+

    The form depends on entity type, income sources, audit position and the relevant assessment year.

    02Can a return be filed before books are final?+

    A reliable return ordinarily requires completed financial information and approved tax adjustments.

    03Does filing include tax audit?+

    No. Audit is a separate engagement and must satisfy eligibility and independence requirements.

    04Can a missed return still be filed?+

    Available options depend on the assessment year, statutory window and the taxpayer's facts.

    05Will you review AIS and Form 26AS?+

    They form part of the tax-data review when relevant and available.

    06Can GST turnover differ from financial statements?+

    Differences can occur, but they should be explained and reconciled rather than ignored.
