Proprietorship for Online Sellers: The Rules Change the Moment You List on a Marketplace
A trader selling the same products from a physical shop can wait until turnover crosses ₹40 lakh before registering for GST. The moment that same trader lists on Amazon, Flipkart, or Meesho, that exemption disappears entirely - GST registration becomes mandatory from the first sale, even if it's for ₹500. This is the single biggest thing that catches new online sellers off guard, and it shapes almost everything else about how a proprietorship operates once it moves online.
Most registration guides treat "proprietorship" as one uniform process regardless of what you sell or where. For an online seller, it isn't - the threshold rules are different, the tax collection mechanics are different, and if you're shipping across states through a marketplace's warehouse network, you may need more than one GST registration before you've made your first hundred sales. This guide covers what specifically changes.
For the underlying registration process - documents, fees, the GST/Udyam/Shop Act sequence - our proprietorship firm registration guide covers the mechanics in full. This one is about what's different once "proprietorship" means "marketplace seller."
Quick Answer
GST registration is mandatory for anyone selling goods or services through an e-commerce operator like Amazon, Flipkart, or Meesho, regardless of turnover - the usual ₹40 lakh (goods) or ₹20 lakh (services) exemption does not apply under Section 24(ix) of the CGST Act. Marketplaces deduct 1% GST TCS and 0.1% income tax TDS under Section 194O from every payout, both of which you claim back as credit when filing. Selling through Amazon FBA or Flipkart's fulfilment network can trigger a GST registration requirement in every state where your inventory is warehoused, not just where your business is based.
Why Online Sellers Don't Get the Usual GST Exemption
Under Section 24(ix) of the CGST Act, 2017, anyone supplying goods or services through an e-commerce operator required to collect tax at source is compulsorily registrable under GST - irrespective of turnover. It works this way because the marketplace itself is legally required to deduct TCS on every seller payout, and that mechanism only functions if the seller already holds a valid GSTIN to receive it against. Most commonly, this catches home-based sellers on Meesho, small artisans on Amazon Karigar, and anyone assuming their sales are "too small" to matter - the ₹40 lakh threshold that applies to an offline shop simply doesn't extend to marketplace sales.
There is one narrow carve-out: under CBIC Notification 34/2023-CT, sellers supplying only intra-state, GST-exempt goods through a marketplace may be relieved of mandatory registration. In practice, this applies to very few sellers - the moment a single taxable item is listed, or a sale crosses a state line, the exemption stops applying and standard registration becomes mandatory again.
TCS Under GST - The 1% That Gets Deducted Before You See It
Every marketplace required to collect TCS deducts 1% (0.5% CGST + 0.5% SGST, or 1% IGST for inter-state supplies) from the net taxable value of your sales before paying you out. This isn't an extra cost - it's tax collected in advance on your behalf and deposited against your GSTIN, which you then claim as credit in your electronic cash ledger when you file. The marketplace reports this collection through its own return, GSTR-8, and the credit shows up against your account once that's filed.
The practical task on your side is reconciliation, not collection - checking that the TCS the marketplace reports against your GSTIN matches what actually landed in your settlement reports before you claim the credit. A mismatch here, however small, is one of the more common reasons online sellers end up with a GST notice they didn't expect.
Income Tax TDS Under Section 194O
Separately from GST TCS, marketplaces also deduct income tax at source under Section 194O - currently 0.1% of the gross sale amount, reduced from 1% effective October 2024. For individual and HUF sellers, this only applies once your annual sales through that platform exceed ₹5 lakh; below that, no TDS is deducted. Sellers who haven't furnished PAN face a steeper 5% deduction instead, which is one more reason to make sure your marketplace account and GSTIN details are consistent from day one.
Like GST TCS, this isn't tax you owe on top of your regular liability - it's advance tax credited to your PAN, visible in Form 26AS, and claimed back at the time of filing your income tax return. The mistake we see most often is sellers treating the amount that actually hits their bank account as their full income, when it's already net of both TCS and TDS - the gross sale value is what needs to be reported.
Multi-State GST - What Happens When Your Stock Sits in Someone Else's Warehouse
If you use Amazon FBA, Flipkart's fulfilment network, or a third-party 3PL, your inventory typically doesn't sit in one place - marketplaces distribute stock across fulfilment centres in multiple states to speed up delivery, often without asking first. Under GST law, storing goods in a state creates a business presence there, which means a separate GST registration for that state, not just your home state's GSTIN extended to cover it.
The common workaround is a Virtual Principal Place of Business (VPOB) registration - a GST registration obtained for a state where you have no physical office of your own, using the fulfilment centre's address as your Additional Place of Business (APOB). Sellers scaling past a handful of states usually end up managing multiple GSTINs this way: one home-state registration under regular ownership, and a VPOB-plus-APOB pair for each additional state where stock is warehoused. It's an administrative layer that a purely offline proprietorship never has to deal with, and it's worth planning for before enrolling in FBA rather than discovering it after a compliance notice.
Presumptive Taxation for Trading Businesses
Most online sellers running a trading business - buying and reselling goods rather than manufacturing them - are eligible for presumptive taxation under Section 44AD, declaring 6% of digital turnover (8% of cash turnover) as taxable income rather than maintaining full books, up to a turnover of ₹2 crore (₹3 crore where 95%+ of transactions are digital, which most marketplace sales are by default). This is filed through ITR-4 and is usually the simplest route for a seller who isn't yet operating at a scale that benefits from claiming actual expenses like warehousing, packaging, and advertising individually.
It stops making sense once your actual costs - Amazon's commission, storage fees, advertising spend, return losses - regularly exceed what the 6-8% presumption would allow you to claim, at which point regular books under ITR-3 usually work out better despite the extra paperwork. Our guide to income tax returns for proprietorship firms covers the ITR-3 vs ITR-4 decision, and the audit thresholds that apply once turnover grows, in more depth.
Invoicing, HSN Codes, and What the Marketplace Doesn't Handle for You
A marketplace deducting TCS doesn't file your GSTR-1 and GSTR-3B for you - those remain your responsibility every month, reporting sales across every channel you use, not just the marketplace. Each product needs a correct HSN code on the invoice, and getting this wrong at the listing stage is a common source of rate mismatches that surface later during return reconciliation, not at the point of sale.
Sales made directly through your own website, if you run one alongside marketplace listings, don't attract TCS the way marketplace sales do - but they still need to be reported in the same GSTR-1 under the same GSTIN. Our guide to GST compliance for sole proprietors covers the monthly filing mechanics, ITC reconciliation, and late fees that apply here in full detail.
Selling Internationally - When an IEC Becomes Relevant
If you sell exclusively within India through a domestic marketplace, an Import Export Code isn't required. It becomes relevant the moment you ship goods outside India - whether through a marketplace's own export program or independently - since customs clearance for goods leaving the country requires an IEC tied to your PAN. Getting one is a separate, one-time online registration, distinct from GST or Udyam, and it's worth applying for early if international expansion is even a mid-term plan, since retrofitting it after you've already committed to an export order adds unnecessary delay.
Common Mistakes Online Sellers Make
Assuming small sales don't need GST registration. The ₹40 lakh threshold that protects an offline trader doesn't apply once you're selling through a marketplace - registration is mandatory from the first sale, regardless of amount.
Treating TCS and TDS credits as optional to reconcile. Both are refundable credits, not extra costs, but only if you actually match them against your GSTR-2B and Form 26AS before filing - skipped reconciliation means leaving your own money unclaimed.
Not registering in states where FBA stock lands. Amazon and Flipkart route inventory across their fulfilment network based on demand, not your registration status - a seller who hasn't set up VPOB/APOB registrations in those states is technically non-compliant the moment stock is placed there, even without intending to expand.
Reporting bank credits instead of gross sale value in ITR. The amount that actually reaches your account is already net of TCS and TDS - your reported turnover needs to be the gross figure, with both deductions claimed back as credits, not treated as if they never existed.
Skipping HSN accuracy at the listing stage. A wrong HSN code doesn't just risk a wrong tax rate on one sale - it compounds across every unit sold under that listing until it's corrected, and cleaning it up retroactively across hundreds of transactions is far more work than getting it right once.
Where This Fits With the Rest of Your Compliance
Selling online adds a few extra layers - mandatory zero-threshold GST, TCS/TDS reconciliation, possibly multi-state registration - on top of the same underlying proprietorship structure every other business uses. If you're setting the firm up from scratch, our proprietorship firm registration guide covers GST, Udyam, and Shop Act registration end to end. From there, GST compliance for sole proprietors covers the monthly filing cycle, and income tax returns for proprietorship firms covers ITR-3, ITR-4, and the presumptive scheme.

Frequently Asked Questions
Is GST registration mandatory to sell on Amazon or Flipkart, even for small turnover?
Yes. Under Section 24(ix) of the CGST Act, anyone selling through an e-commerce operator that collects TCS must register for GST regardless of turnover - the usual ₹40 lakh exemption for goods doesn't apply to marketplace sellers.
What is TCS, and is it an extra tax I pay?
TCS is 1% deducted by the marketplace from your sale proceeds and deposited against your GSTIN as an advance tax credit, not an extra cost - you claim it back against your GST liability when you file your returns.
Do I need a separate GST registration for every state where Amazon stores my inventory?
In most cases, yes, if you use Amazon FBA or a similar fulfilment network. Storing goods in a state creates a business presence there under GST law, typically handled through a VPOB (registration) plus APOB (the warehouse address) for each additional state.
How is income tax different for an online seller compared to an offline shop?
The tax computation itself - presumptive taxation under 44AD, or regular books under ITR-3 - works the same way for both. What differs is the TDS mechanism: marketplaces deduct 0.1% under Section 194O on payouts above ₹5 lakh a year, which offline sellers don't encounter since there's no intermediary platform involved.
Can a home-based seller use their residential address for GST registration as an online seller?
Yes, a residential address is accepted for the GST registration tied to your home state. Where it gets more involved is registrations for states where your marketplace stock is warehoused - those typically use the fulfilment centre's address as an Additional Place of Business rather than your home address.
