Income Tax & TDS / Income Tax Returns
Business and Proprietorship ITR Filing
Income tax return for proprietors, traders, freelancers and professionals, under presumptive taxation (ITR-4) or regular books (ITR-3), with GST and AIS reconciliation and coordination with a tax auditor where needed.
Overview
A sole proprietor is taxed as an individual, so business or professional profit is reported in the individual's own return. Which form applies depends on how profit is worked out:
- ITR-4 (Sugam) when you opt for presumptive taxation, where income is taken as a fixed percentage of turnover or receipts and detailed books are not required.
- ITR-3 when profit is computed from regular books, a profit and loss account and a balance sheet. This is also used by partners in firms, by traders with capital gains and by anyone whose accounts are audited.
This service prepares and files the correct return for AY 2026-27 (income of FY 2025-26) or an earlier year, tied to your books, GST returns and TDS credits.
Who needs it
- Proprietors of shops, trading, manufacturing and service businesses.
- Freelancers, consultants and professionals such as doctors, lawyers and architects.
- Transport operators with goods vehicles.
- Individuals and HUFs with business income alongside salary, rent or capital gains.
- Partners of firms who earn remuneration or interest from the firm.
Businesses with a loss should also file on time, because a loss can be carried forward for up to eight years only if the return is filed by the due date.
What Zenith does
We begin with a conversation about how the business runs, what books exist and what has been filed before. We then confirm scope, share a tailored quotation, an assignment-specific checklist and your relationship manager.
- Decide between presumptive taxation and regular books for the year, and explain the trade-offs.
- Check whether a tax audit is triggered; if it is, coordinate with an authorised professional who is separately engaged and signs the audit report.
- Reconcile turnover with GST returns, bank credits, Form 26AS and AIS.
- Prepare the financial statements schedule (ITR-3) or the presumptive computation (ITR-4), depreciation, deductions and the tax payable.
- File the return, help you e-verify and hand over the acknowledgement with a short explanation of the computation.
You receive milestone updates. Representation before authorities, if ever needed, is only through appropriately authorised professionals.
Eligibility and key rules
Presumptive schemes (ITR-4)
| Scheme | For | Basis (as per sources read) | Receipts limit |
|---|---|---|---|
| Section 44AD | Small businesses (not agents or commission businesses) | 6% of digital receipts and 8% of other receipts | Up to ₹3 crore |
| Section 44ADA | Specified professionals | 50% of gross receipts | Up to ₹75 lakh |
| Section 44AE | Goods transport, up to 10 vehicles | Fixed amount per vehicle per month (₹1,000 per tonne of capacity for heavy vehicles, ₹7,500 for others) | Vehicle count |
The higher receipt limits apply only where cash receipts are small, so Zenith confirms which limit applies to you. ITR-4 is generally not available with more than one house property, foreign assets or income, or agricultural income above ₹5,000. Capital gains normally push the return to ITR-2 or ITR-3.
Books and audit
Books of account are expected where business turnover has crossed ₹25 lakh or income ₹2.5 lakh in any of the three preceding years. A tax audit under Section 44AB generally applies when turnover passes ₹1 crore for businesses or gross receipts pass ₹50 lakh for professionals, with higher limits where cash dealings are small, and in certain cases where presumptive income is declared below the deemed rate. A tax audit moves the ITR due date from 31 July to 31 October.
Documents required
- PAN and Aadhaar of the proprietor.
- Profit and loss account and balance sheet as on 31 March; where no books are kept, a statement of receipts and payments.
- Bank statements of all business accounts.
- GST returns filed during the year, for turnover reconciliation.
- Form 26AS, AIS, and Form 16A from clients who deducted TDS.
- Advance tax and self-assessment tax challans.
- Details of fixed assets bought or sold (for depreciation and capital gains).
- Tax audit report (Form 3CB-3CD), if applicable.
- For Section 44AE: registration details and number of vehicles.
- Loan statements and investment proofs if deductions are claimed.
Process and timeline
- Scoping and quotation; you upload the checklist documents.
- We check form eligibility, audit applicability and GST-to-books reconciliation.
- Computation is prepared; you review profit, deductions and tax payable.
- Tax shortfall, if any, is paid on the portal.
- We file and share the acknowledgement; you e-verify within 30 days.
- Intimation and refund follow after department processing.
Timelines depend on completeness of records, complexity of accounts and authority processing.
Government fees, penalties and due dates
There is no government fee to file. The usual dates and consequences are:
| Item | Rule |

| Tax audit report | 30 September 2026 (shown on the department portal) |

Advance tax is payable in instalments by 15 June (15%), 15 September (45%), 15 December (75%) and 15 March (100%) where estimated liability exceeds ₹10,000. Late filing can also cost loss carry-forward, and wilful non-filing can invite prosecution.
Amounts and dates above reflect public sources read in October 2026 and change with notifications, so Zenith confirms the current figures in your quotation.
Common mistakes
- Filing ITR-1 or ITR-2 when there is business income.
- Declaring turnover in the return that does not match GST returns or bank credits.
- Choosing presumptive taxation without checking eligibility, or opting out later without understanding the consequences.
- Missing TDS credits shown in Form 26AS.
- Mixing personal and business transactions so that expenses cannot be supported.
- Ignoring advance tax instalments and paying interest later.
- Reporting exempt income such as agricultural income incorrectly.
FAQs
Do I need to maintain books if I use presumptive taxation?
Detailed books are not required under 44AD or 44ADA, but you should still keep sales records, bank statements and GST data.
Can a freelancer use ITR-4?
Yes, if eligible as a specified professional under 44ADA within the receipts limit, and the other conditions of the form are met.
Do I need to pay advance tax?
Yes, where estimated tax is above ₹10,000. Salary-only taxpayers may be covered by TDS, but business income usually is not.
When is a tax audit required?
When limits under Section 44AB are crossed or presumptive conditions are not met. Zenith checks this before choosing the form.
Can I carry forward a business loss?
Yes, if the return is filed on time, for up to eight years.
What if I filed late?
A belated return can be filed up to 31 December 2026 for AY 2026-27 with fee and interest, but loss carry-forward is generally lost.
