Professional Business ITR Filing for Companies, LLPs & Firms - Starting @ ₹4,999 Only
Corporate Tax, Partnership Firm Tax, LLP Tax & Proprietorship Tax Filing with Audit Coordination.
"Business tax filing" isn't a single, uniform obligation — what it actually involves depends heavily on how the business is structured. A company must file ITR-6, verified compulsorily through a Digital Signature Certificate, with no alternative verification mode available. An LLP or partnership firm files ITR-5, carrying its own set of partner-related schedules. A sole proprietorship files either ITR-3, where regular books of account are maintained, or ITR-4, where presumptive taxation under Sections 44AD/44ADA is being used instead.
Layered on top of the entity-specific form is the question of audit. Once turnover, receipts, or a presumptive opt-out crosses the thresholds under Section 44AB, a tax audit becomes mandatory before the return can be filed — and for companies, a separate Companies Act statutory audit is required regardless of scale. Companies additionally have to work out Minimum Alternate Tax (MAT) under Section 115JB wherever their normal tax liability falls below 15% of book profit, while LLPs face the equivalent Alternate Minimum Tax (AMT) under Section 115JC.
It's worth being clear about what business tax filing is not: it is not the same compliance as GST return filing or TDS/TCS return filing. Those are separate, periodic obligations under different statutes — monthly or quarterly filings that run alongside, not instead of, the single annual income tax return. A GST-registered business still has to file its ITR every year regardless of how current its GST returns are, and vice versa.
| Parameter | Details |
|---|---|
| Governing Law | Section 139 of the Income-tax Act, 1961, read with Rule 12 of the Income-tax Rules, 1962, with the applicable ITR form determined by entity type |
| Applicable ITR Forms | ITR-3 (proprietorship/professional with books of account), ITR-4 (presumptive proprietorship), ITR-5 (partnership firm/LLP), ITR-6 (company) |
| Tax Audit Trigger | Section 44AB — turnover, receipts, or presumptive opt-out crossing prescribed thresholds mandates an audit before filing |
| MAT / AMT | Section 115JB imposes Minimum Alternate Tax on companies; Section 115JC imposes Alternate Minimum Tax on LLPs and other non-corporate taxpayers claiming specified deductions |
| Verification Mode | Mandatory DSC for companies; DSC or EVC/Aadhaar-based verification for other entities depending on audit applicability |
| Distinct From | GST return filing and TDS/TCS return filing — separate, periodic compliances under different statutes, running alongside the annual income tax return |
Business income is reported on different forms depending on structure — we identify the correct one for your entity and income profile rather than defaulting to a one-size-fits-all form.
Where turnover, receipts, or a presumptive opt-out crosses the Section 44AB threshold, we coordinate the audit process alongside your Chartered Accountant so the ITR and the audit report align cleanly.
Companies compute Minimum Alternate Tax under Section 115JB and LLPs compute Alternate Minimum Tax under Section 115JC — we calculate the liability and track any resulting credit for future years.
We help estimate quarterly advance tax instalments across the year based on projected income, reducing the risk of interest charges under Sections 234B and 234C at filing time.
For companies and other DSC-mandated filings, we handle the digital signature verification step so the return is validly filed the first time, without a rejected or defective submission.
TDS, TCS, and specified transactions reported against your PAN are checked line by line against your own books before filing, catching mismatches before the department does.
If a routine reconciliation or scrutiny notice arrives after your return is processed, we help you understand what it's asking for and prepare an appropriate response.
Business losses, capital losses, and unabsorbed depreciation carried forward from earlier years are tracked and correctly set off in the current computation, so nothing gets left unclaimed.
The applicable ITR form, verification mode, and special tax provisions all shift depending on how your business is structured.
| Entity Type | Applicable ITR Form | Verification Mode | Key Tax Provision |
|---|---|---|---|
| Private / Public Limited Company | ITR-6 | Digital Signature Certificate (DSC) of an authorised signatory — mandatory, with no alternative verification mode available | Minimum Alternate Tax (MAT) under Section 115JB, applicable whenever tax computed on normal income is less than 15% of book profit |
| Limited Liability Partnership (LLP) | ITR-5 | DSC of a designated partner, mandatory wherever the LLP's accounts are subject to audit | Alternate Minimum Tax (AMT) under Section 115JC, applicable whenever tax on normal income is less than 18.5% of adjusted total income |
| Partnership Firm | ITR-5 | DSC where audit applies; otherwise EVC or Aadhaar-based verification by an authorised partner | Partner remuneration and interest deductibility governed by Section 40(b), subject to prescribed limits and conditions |
| Sole Proprietorship | ITR-3 (regular books of account) or ITR-4 (presumptive income) | Aadhaar OTP, net banking, or DSC — the same individual verification options available to any personal taxpayer | Choice between presumptive taxation under Section 44AD/44ADA and regular computation from maintained books of account |
Some triggers make audit and professional filing legally mandatory; others are reasons a business chooses to file carefully even without a strict legal push.
| Category | Trigger / Condition | Why It Matters |
|---|---|---|
| Mandatory — Business Turnover Audit Threshold | Turnover exceeds ₹1 crore in a year, raised to ₹10 crore where cash receipts and cash payments each stay within 5% of the total transaction value | Crossing this threshold triggers a tax audit under Section 44AB regardless of whether the business made a profit |
| Mandatory — Professional Gross Receipts | Gross receipts of a professional exceed ₹50 lakh in a year | The same Section 44AB audit obligation applies to professionals, independently assessed from the business turnover threshold |
| Mandatory — Presumptive Scheme Opt-Out | Declared profit falls below the prescribed presumptive rate under Section 44AD/44ADA in a year total income exceeds the basic exemption limit | Opting out of a presumptive scheme that was used in an earlier year can itself trigger a mandatory audit in specified circumstances |
| Mandatory — Company Verification | Applies to every company, regardless of turnover or profitability | ITR-6 cannot be verified through Aadhaar OTP or EVC — a Digital Signature Certificate of an authorised signatory is the only accepted mode |
| Voluntary — Computation Accuracy | Complex income streams — multiple business verticals, depreciation schedules, or related-party transactions | Professional review reduces the risk of an incorrect schedule or a reconciliation mismatch that draws department attention |
| Voluntary — Loss Carry-Forward Eligibility | Business or capital losses intended to be carried forward and set off against future income | Carry-forward is available only where the return is filed by the original due date under Section 139(1) |
| Voluntary — MAT/AMT Credit Tracking | Companies or LLPs that paid MAT/AMT in excess of their normal tax liability in a given year | The resulting credit under Section 115JAA/115JD must be tracked and correctly claimed in a future year when normal tax exceeds MAT/AMT |
ComplianceBharo's business tax filing packages start at ₹4,999 as a professional fee for end-to-end assistance. Where the exact price lands within and beyond that starting point depends on a handful of factors specific to your business: the entity type (a company's ITR-6 with mandatory DSC and MAT computation is inherently more involved than a proprietorship's ITR-4), whether a statutory or tax audit applies, the volume of transactions requiring reconciliation, the complexity of any MAT/AMT calculation and credit tracking, and whether the business operates across multiple verticals or income streams that each need separate computation.
We confirm the exact scope and final professional fee with you upfront, after reviewing your entity type and financials, so there are no surprises once the filing is underway.
The document checklist follows your entity type — here's what's typically needed for each.
Gather bank statements, sales/purchase records or financial statements, prior-year returns, and TDS certificates for the year, so the return is built on a complete financial picture.
Check turnover, receipts, and presumptive-scheme history against the Section 44AB thresholds to confirm whether a tax audit is legally required before the return can be filed.
Where audit applies, coordinate with the Chartered Accountant conducting it — companies additionally need their Companies Act statutory audit completed before the ITR figures are finalised.
Arrive at total income under the applicable heads, apply the relevant tax rate or regime, and separately compute MAT (for companies) or AMT (for LLPs and other eligible entities) where it applies.
Match TDS, TCS, advance tax payments, and reported transactions against the business's own books, resolving any mismatch before it becomes a reconciliation notice.
Submit ITR-3, ITR-4, ITR-5, or ITR-6 as applicable, completing DSC-based verification for companies and any other filing that mandates it.
Monitor the return's processing status on the e-filing portal and follow up on any refund due or notice raised once the department has processed the filing.
The tax audit report deadline falls a full month ahead of the ITR due date for audit-liable businesses — the audit has to close before the return can realistically be finalised.
