Running a business in India means you must file your Income Tax Return (ITR) under the Income Tax Act 1961 every year, regardless of profit or loss. If you are a proprietorship, partnership, LLP, company, or trust earning income, non-filing or delayed filing attracts a penalty of up to Rs 10,000 under Section 234F, plus interest on any tax dues. For Assessment Year 2025-26, the Income Tax Department has already released updated ITR forms and the e-Filing portal at incometax.gov.in is fully operational for AY 2026-27 filings. Businesses with turnover above Rs 10 crore that require a Tax Audit under Section 44AB must file by the extended deadline of October 31, 2026. Every non-compliance also feeds into your MCA compliance score and affects future loan eligibility and government contract participation. KAMRIT Financial Services LLP manages the entire ITR Filing (Business) lifecycle for you: from data collection and form selection (ITR-3 or ITR-4 as applicable) to pre-filing validation, e-Verification via Aadhaar-linked OTP or Digital Signature Certificate, and delivery of the filed Acknowledgement (ITR-V) or confirmation intimation. We ensure zero errors in Schedule/business income computations, correct applicability of Presumptive Taxation under Section 44AD, and compliance with the new Rule 12B for audit-report upload before filing.
What is ITR Filing (Business) in India 2026?
Income Tax Return (ITR) Filing for businesses is the statutory process of reporting your entity's income, deductions, taxes paid, and tax liability to the Income Tax Department of India through the centralised e-Filing portal (incometax.gov.in). It is governed by Section 139 of the Income Tax Act 1961, read with the Income Tax Returns (Classes) Rules 2006 and the annual CBDT notification for ITR forms. Every business entity that has earned income during a Financial Year (April 1 to March 31) must file a return for the relevant Assessment Year (AY). The applicable ITR form depends on your business structure: ITR-3 is used by firms, LLPs, and proprietary businesses with income from business or profession; ITR-4 is used by businesses opting for Presumptive Taxation under Sections 44AD, 44ADA, or 44AE. Companies always use ITR-6. The filing window opens on April 1 every year and closes on the statutory due date (July 31 for companies and persons requiring audit, October 31 for persons requiring transfer pricing audit, and November 30 for other entities for AY 2025-26). The Income Tax Department owns the process entirely. KAMRIT manages the compliance layer: form selection, data compilation across all income heads, tax credit reconciliation from Form 26AS, and submission with supporting documents such as Audit Report (Form 3CA-CDB/3CB-CDB for audited entities), Transfer Pricing Report (Form 3CEB for international transactions), and Balance Sheet and P&L statement prepared under Schedule III of the Companies Act 2013 or as applicable.
Who needs this
Not every business entity files the same way. Eligibility for ITR Filing (Business) is driven by turnover, income type, audit requirements, and registration status under Indian law.

How KAMRIT runs it, step by step
KAMRIT's filing process is structured across eight sequential stages. Stages 1 through 4 are KAMRIT-controlled. Stages 5 through 8 involve Department submission and intimation timelines.
- Kickoff and Data Collection. On engagement, KAMRIT shares a document checklist customised to your business structure and income type. You upload scanned copies via our secure client portal. We need your PAN-linked Aadhaar details, GSTIN (if registered), entity registration certificates, and bank statements for the full Financial Year. This stage takes 1 to 3 working days depending on the completeness of data received from the client.
- Income Heads Classification and Form Selection. KAMRIT's tax team classifies all income under the applicable heads: Business Income under Section 28, Income from Other Sources under Section 56, and House Property Income under Section 22 to 27. We select the correct ITR form (ITR-3 for general businesses, ITR-4 for Presumptive, ITR-6 for companies). We also determine if audit applicability under Section 44AB is triggered by reviewing your turnover figures. This stage takes 1 to 2 working days after data receipt.
- Pre-Filing Validation on Income Tax Portal. KAMRIT pre-fills data from Form 26AS, AIS (Annual Information Statement), and TDS certificates downloaded from the TRACES portal. We reconcile GST turnover with ITR turnover, cross-check HSN reporting, and flag discrepancies before data entry on the e-Filing portal. For companies and LLPs, we also verify DIN of directors and Designated Partners' DPIN on the MCA portal for consistency with ITR filings.
- Tax Computation and Deduction Review. KAMRIT computes the total income, applies deductions under Chapter VIA (80C, 80D, 80G, 80GGC, 80IE as applicable), calculates tax liability under the applicable slab or Section 115B for companies, and applies MAT provisions where applicable (Section 115JB for companies with book profit). We also compute deferred tax, and advise on advance tax instalment liability under Section 208 to avoid interest under Section 234B and 234C.
- Upload of Audit Reports and Transfer Pricing Documents. For entities requiring tax audit, KAMRIT uploads Form 3CA-CDB or Form 3CB-CDB along with the chartered accountant's digital signature on the e-Filing portal under the electronic filing module before ITR submission. Transfer Pricing documentation including Form 3CEB and the master file/local file (for entities meeting Section 92E thresholds) is attached in the same module.
- ITR Submission and Payment of Tax Dues. KAMRIT submits the completed ITR form with a digital signature (for companies, LLPs, and persons with audit requirement) or via Aadhaar-linked e-Verification OTP (for other entities). If tax is payable, we generate the challan (ITNS 280) for advance tax or self-assessment tax and confirm payment via net banking or NEFT/RTGS against BSR codes. The filing is timestamped on the portal immediately on successful submission.
- e-Verification and Acknowledgement Receipt. Upon successful filing, the Income Tax Department sends an Acknowledgement (ITR-V for manual verification or a direct confirmation for e-Verified returns). KAMRIT downloads and stores the Acknowledgement (PDF with unique acknowledgment number), verifies the PAN, name, and tax paid details match our records, and sends the document to you within 1 working day of filing. If e-Verification via Aadhaar OTP was used, no further action is needed.
- Post-Filing Compliance and Intimation. The Income Tax Department typically sends an intimation under Section 143(1) within 1 to 6 months of filing, reconciling the tax computed by the Department against the return filed. KAMRIT reviews this intimation, flags any discrepancy, and responds under Section 246A if you disagree with the assessment. We also track refund dispatch or demand notice receipt and manage subsequent correspondence until the filing cycle is fully closed for the Assessment Year.
Timeline
From the day KAMRIT receives complete documents, the filing preparation stage (Steps 1 through 4) takes 3 to 5 working days for simple businesses with minimal transactions, and 8 to 12 working days for entities requiring tax audit, transfer pricing documentation, or GST reconciliation across multiple quarters. The audit report upload stage (Step 5) adds 1 to 2 working days after the chartered accountant's digital signature is obtained. The ITR submission itself (Step 6) is completed on the same day the form is finalised and payment confirmed. Post-filing intimation under Section 143(1) arrives within 30 to 90 calendar days in most cases; however, the Department may select the return for a limited scrutiny or comprehensive scrutiny under Section 143(2) and 144, which can extend the total compliance cycle to 6 to 18 months. KAMRIT manages all Department communications on your behalf during this period at no additional charge for the relevant Assessment Year. Total estimated end-to-end timeline: 5 to 15 working days from kickoff to Acknowledgement receipt for straightforward filings, and 15 to 30 working days for audited entities.
How our pricing compares
KAMRIT's ITR Filing (Business) service starts at Rs 3,499 for proprietorship and small business entities with straightforward income and no audit requirement. For businesses requiring tax audit under Section 44AB, the fee is custom-quoted based on turnover and complexity. ClearTax charges between Rs 4,999 and Rs 14,999 for comparable ITR-3 and ITR-4 business filings depending on the plan tier, with additional charges of Rs 1,500 to Rs 3,000 for audit report upload handling. IndiaFilings and Vakilsearch typically price business ITR filing between Rs 3,999 and Rs 8,999 for non-audit cases and Rs 15,000 to Rs 30,000 for audit-linked cases, though their turnaround is 7 to 14 working days for standard filings. LegalRaasta offers basic business ITR filing starting at Rs 2,499 but charges separately for PAN changes, TDS reconciliation, and GST-to-ITR reconciliation, pushing effective cost above Rs 5,000 for operating businesses. KAMRIT's starting price of Rs 3,499 is competitive with ClearTax and cheaper than Vakilsearch for the standard filing, and it includes GST-to-ITR reconciliation, Form 26AS cross-check, and one revision within 30 days of original filing. Government fees of Rs 100 for e-Verification via DSC if applicable are passed through at cost. KAMRIT's pricing advantage stems from our in-house tax preparation team and standardised document checklists that reduce back-and-forth, delivering faster turnaround without compromising on compliance accuracy. Honest clarification: Form 16, GST returns, and bank statements must be provided by you in complete form; delays in your document supply can extend timelines and may attract additional charges for extended engagement beyond the initial scope.
Common mistakes KAMRIT avoids
First-time business filers and even experienced taxpayers make avoidable errors that trigger notices, additional tax demands, or refund delays. KAMRIT reviews and prevents these during our preparation stage.
- Filing under the wrong ITR form (e.g., using ITR-1 for business income) which causes the return to be invalidated under Section 139(9) and attracts a notice for a defective return
- Incorrect turnover declaration: reporting GST turnover instead of gross receipts or vice versa, leading to a mismatch with AIS and triggering a Section 143(2) scrutiny notice
- Not reconciling Form 26AS TDS credits with actual certificates received: missing credits mean the Department believes tax was underpaid, adding to interest liability under Section 234B
- Failing to upload audit report (Form 3CA-CDB/3CB-CDB) on the e-Filing portal before filing the ITR, which is now a mandatory pre-condition under the Income Tax Rules
- Incorrectly applying Presumptive Taxation under Section 44AD and under-reporting income, which triggers a notice when GST turnover is significantly higher than declared profit
- Not filing Form 67 for carryforward of losses when income is below the basic exemption threshold, losing the ability to set off brought-forward losses in future years
- Claiming deductions under Section 80C or 80D without adequate supporting evidence: the Department disallows claims and adds back to total income, increasing tax liability
- Missing the due date for companies and audit-requiring entities (July 31 or October 31) and attracting a late filing fee of Rs 5,000 (or Rs 10,000 if total income exceeds Rs 5 lakh) under Section 234F plus interest on any outstanding tax
