Income Tax Return for Business Owners
Which ITR your business files depends on its structure — proprietor, firm, LLP or company — and whether you choose the 6%/8% presumptive route under Section 44AD or report actual profits. Here is the full map, the 31 August 2026 deadline, and exactly when a tax audit kicks in.
Does my business file an ITR — and which one?
Every business with income files a return; the form depends on how the business is set up. A sole proprietor reports business income in their own name and is taxed at slab rates. A firm, LLP or company files separately at a flat rate. Get the structure right first, then pick your route.
Which ITR form, by business structure
The first fork is not presumptive-vs-actual — it is your legal structure. That decides your form and your tax rate, before any scheme choice.
Proprietors: the two filing routes
If you run an unincorporated business, you choose how to declare profit — a flat presumptive percentage of turnover, or your actual profit after real expenses. The rule of thumb: if your true margin is higher than the presumptive rate, the presumptive route saves both tax and bookkeeping.
Presumptive route
Actual income route
Section 44AD in plain numbers
Under 44AD, your profit is simply a fixed slice of turnover — 8% on cash receipts, 6% on digital receipts — and that figure is taxed at your slab rate. The lower digital rate is a deliberate nudge toward banked payments.
Worked example — trader, ₹1 crore turnover, mostly digital
Who can use it: resident individuals, HUFs and partnership firms (LLPs are excluded), with turnover up to ₹2 crore — or ₹3 crore if at least 95% of receipts are digital. It does not cover professionals (they use 44ADA), agency or commission businesses, or goods-carriage operators under Section 44AE.
Four compliance triggers every business owner must track
When a tax audit applies
A regular-route business needs a tax audit once turnover crosses ₹1 crore — lifted to ₹10 crore if both receipts and payments are 95%+ digital. An audit also kicks in if you declare below the presumptive rate and your income exceeds the exemption limit. Audit report is due 30 Sep 2026; the return then by 31 Oct 2026.
Advance tax
If your tax for the year exceeds ₹10,000, advance tax applies. Under 44AD you pay 100% in one instalment by 15 March; on the regular route it is four instalments across the year. Shortfalls attract interest under Sections 234B and 234C.
Regime & Form 10-IEA
The new regime is default, with income up to ₹12 lakh tax-free for a resident proprietor via the 87A rebate (no standard deduction on business income). To use the old regime, file Form 10-IEA before the due date — and a business owner can switch back to the new regime only once.
GST & TDS
GST registration is mandatory once turnover crosses ₹40 lakh for goods or ₹20 lakh for services. As a business you also deduct TDS on certain payments (194C, 194J, 194H) and claim credit for TDS on your own receipts — reconcile it all in 26AS and AIS. GST registration ›
Your business return is where the next decision shows up
Once your profit is steady, the proprietorship that was simple to start quietly becomes the costliest way to be taxed — every rupee lands on your personal slab, and there is no liability shield between you and the business. Filing season is the natural moment to ask whether an OPC or Pvt Ltd structure now saves tax and protects you.
- Dual computation — 44AD vs actual profit — so you file the lower-tax route
- The five-year lock-in modelled against your growth before you opt in
- Tax audit handled cleanly if your turnover has crossed ₹1 crore
- Structure review — proprietor vs OPC vs Pvt Ltd for tax, liability and credibility

Does 44AD really lock me in for five years?
My turnover crossed ₹1 crore. Do I need a tax audit?
Proprietor or company — which is taxed less?
Is the ₹12 lakh zero-tax limit available to business owners?
