The composition scheme exists to reduce the compliance load on smaller businesses. Whether it suits yours is a question for your CA. What this article covers is the part that changes daily: what it does to your billing.
The core trade
Broadly, a composition dealer pays tax at a reduced rate on turnover and files less often, in exchange for real restrictions on how they operate. The restrictions are the part worth understanding before opting in, not after.
Eligibility depends on turnover limits and on the nature of the business, and both have been revised over the years. This article does not quote current figures for exactly that reason.
The document rule that catches people out
A composition dealer cannot issue a tax invoice. They issue a bill of supply instead.
The reason is straightforward once stated: a composition dealer cannot collect tax from customers. A tax invoice shows tax being collected. Issuing one would be stating something about your registration that is not true.
A bill of supply carries no tax split, and it must carry a declaration identifying you as a composition taxable person. That declaration is not decoration; it is how the person receiving the document knows why there is no tax on it.
What your customers lose
Because no tax is charged, a business customer cannot claim input tax credit on what they buy from you. For a shop selling mostly to consumers, that is irrelevant. For one selling to other businesses, it is a genuine commercial consideration, and it is the factor most often overlooked when weighing the scheme.
If you switch, your billing has to switch too
Moving into or out of the scheme changes which document you issue from that point forward. It is not a settings detail; it is the difference between a compliant document and a non-compliant one.
This is a good reason to keep registration status as a property of your business record rather than something chosen per sale. Set it once, and every document that follows is the right kind.
What does not change
You still need proper records: what you sold, to whom, when, and for how much. The scheme reduces filing frequency; it does not reduce the need to know your own numbers. Anyone treating it as permission to keep looser records has misread it.
Questions worth asking before opting in
The scheme is not simply the easier option. It is a trade, and these four questions surface whether the trade suits your business.
Who are your customers? If a meaningful share are registered businesses buying for their own use, they lose credit on everything they buy from you, and some will notice.
Are you buying inputs with tax on them? A composition dealer cannot claim credit on purchases either. For a business with substantial taxed inputs, that changes the arithmetic considerably.
Do you sell across state lines? The scheme carries restrictions on inter-state supply that catch out businesses planning to expand.
How close are you to the turnover limit? Crossing it means moving out mid-year, and the billing change that comes with it.
Leaving the scheme is a real event
Businesses tend to plan for opting in and not for opting out, but the exit is the more disruptive of the two.
From the point you leave, your documents change type, your filing obligations change, and your pricing may need revisiting because you are now collecting tax you previously were not. None of that is difficult, but all of it is easier when it is expected.
Practically: if you are anywhere near the threshold, it is worth knowing in advance what your billing setup will need to change, so the switch is a settings change rather than a scramble.
What the scheme is not
It is not an exemption from record-keeping, and it is not a reason to issue documents casually. The document rules are arguably stricter, because the declaration on a bill of supply is doing real work: it explains to the recipient why there is no tax to claim.
A final word on advice. Whether this scheme suits your business depends on your customers, your input costs, your turnover and your growth plans, and those combine differently for every shop. This article is written to help you ask better questions, not to answer them.
The decision itself belongs with your CA, who can see your actual numbers. What is worth walking in with is a clear picture of who your customers are and whether any meaningful share of them are registered businesses, because that single fact often settles the question before the arithmetic starts.
How Vanij handles this
Vanij takes registration status from your business profile. Set as a composition dealer, it issues bills of supply with the required declaration and without tax columns, and switching status later changes the document type going forward without disturbing your existing records.
