GST for professionals: know when the ₹20 lakh line matters — and when registering early pays
Consultants, developers, designers, doctors with non-exempt income and freelancers all face the same three questions: must I register, should I register anyway, and what happens once I do. This page answers all three honestly — including when GST would only cost you money.

₹20 lakh — but read the fine print on "aggregate"
A Gujarat-based supplier of services must register for GST when aggregate turnover crosses ₹20 lakh in a financial year. Two words in that sentence do the real work.
"Aggregate" means everything under your PAN, all-India: taxable fees, exempt income and export receipts, added together. A doctor earning ₹18 lakh from exempt clinical practice and ₹4 lakh from taxable pharma consulting is at ₹22 lakh — over the line. A developer billing ₹15 lakh to Indian clients and ₹8 lakh to a US client is at ₹23 lakh, even though exports are zero-rated. Counting only "taxable" income is the classic miscalculation.
"Services" matters because the goods threshold (₹40 lakh in Gujarat) does not apply to you — and neither does the harshest e-commerce rule: professionals supplying services inter-state keep the ₹20 lakh exemption, per Notification 10/2017-Integrated Tax. Serving clients in five states from a desk in Vadodara does not, by itself, force registration.
Doctors deserve a specific word. Clinical healthcare is broadly exempt, which is why most practices correctly ignore GST. The trap is the non-exempt periphery: many cosmetic procedures, brand promotion, hospital administrative contracts, commercial rent, paid lectures. When those streams grow, the arithmetic above starts to matter. Our article do I need GST registration works through borderline cases.
Foreign clients: zero-rated, not tax-free by accident
The best-paid segment of Indian freelancing — overseas clients paying in foreign currency — gets favourable GST treatment, but only through the correct gate. Export of services is zero-rated: no GST burden on the supply, with input credits preserved. Once registered, you reach that outcome one of two ways:
- File a Letter of Undertaking (LUT) in Form RFD-11 and invoice foreign clients without charging IGST — the route nearly every freelancer takes; or
- Pay IGST and claim refunds — workable, but it parks your cash with the department between filing and refund.
The LUT is filed online, costs nothing in government fees, and is valid for one financial year — a fresh one is due before 31 March for the year ahead, a renewal we diarise for every export client. The condition attached: for services, payment must arrive in convertible foreign exchange (or INR where permitted) within one year of the invoice, failing which IGST plus 18% interest becomes payable. Full mechanics are on our LUT filing page, with a plain-language primer at GST LUT explained.
One nuance worth professional advice: whether an arrangement legally qualifies as "export of services" depends on conditions including the place of supply and currency of receipt. Payment gateways, intermediary arrangements and Indian subsidiaries of foreign clients can complicate it — we flag doubtful cases before you build a pricing model on the wrong assumption.
Invoicing like a registered professional
Registration changes your paperwork from "whatever the client accepts" to a prescribed tax invoice. The essentials every invoice needs:
| Element | Detail |
|---|---|
| Your identity | Name, address and GSTIN, exactly as registered |
| Invoice number & date | Consecutive numbering within the financial year — gaps and duplicates surface in scrutiny |
| Client details | Name and address; GSTIN if the client is registered (that is what routes credit to them) |
| Service description & value | What was supplied and the taxable amount |
| Tax, shown separately | CGST + SGST for clients in Gujarat; IGST for other states; no tax line on LUT export invoices — state the supply is zero-rated under LUT instead |
Every invoice you issue should reappear, identically, in your GSTR-1 — registered clients compare their credit statements against your invoices and chase you when one is missing. E-invoicing obligations begin only at ₹5 crore turnover, so a typical practice will not need IRP reporting for years.
Twelve filings a year, or four?
By default, a registered professional files GSTR-1 by the 11th and GSTR-3B by the 20th of every month. The QRMP scheme — open up to ₹5 crore turnover, covering essentially every independent practice — swaps that for quarterly returns: GSTR-1 by the 13th and GSTR-3B by the 22nd of the month after each quarter (Gujarat's date), with tax for the first two months still deposited monthly through PMT-06 by the 25th.
For a consultant issuing four or five invoices a month, quarterly filing is genuinely lighter. The catch involves your clients: invoices reported quarterly reach their credit statements quarterly too, unless you use the optional monthly IFF to push B2B invoices through sooner. Practices whose corporate clients reconcile credits monthly often stay monthly purely for their comfort. The decision framework is in QRMP scheme explained; either way, nil months still need nil returns — see GST late fees and interest.
Below ₹20 lakh: three good reasons to register anyway — and one bad one
Good reason one: your clients ask for it. Companies prefer vendors who issue tax invoices, because GST paid to you comes back to them as input credit. Freelancers have lost retainers to "GST-registered vendors only" procurement policies. If your pipeline is corporate, a GSTIN is a commercial asset.
Good reason two: input tax credit. Laptops, software, co-working rent — most carry 18% GST you simply absorb while unregistered. Registered, that tax offsets what you collect. A practice spending ₹3 lakh a year on taxable inputs leaves roughly ₹54,000 of credit unclaimed by staying out.
Good reason three: exports. The LUT route is available only to registered persons. Serious foreign-client income usually justifies registering well before ₹20 lakh.
The bad reason: appearances alone. If your clients are households — tuition, personal styling, consumer photography — none can claim credit, so GST either inflates your price 18% or comes out of your margin. Add twelve months of return obligations and registration becomes pure cost. Prestige is not a tax strategy.
Registration, when you proceed, is the standard portal process — free of government fee, Aadhaar-authenticated, typically approved within 7 working days — described on our registration page, with the document list on the printable checklist.
When you do NOT need this service — and what we cannot do
Under ₹20 lakh, consumer clients, no exports, modest input spending: stay unregistered and revisit yearly — that is our genuine advice, given free on WhatsApp. Purely exempt practices usually need nothing from this page. And the limits of our role: we are facilitators, not the tax department. We cannot guarantee approval or its speed, and for contested questions or litigation we will tell you plainly when you need a chartered accountant or counsel instead of us.
Fixed fees, practitioner-handled
GST files at Harsiddhi Services are handled under a registered GST practitioner (PID 242000004888GPL) at our Vadodara office, in service since 2017:
- Registration — ₹499 one-time: documents, REG-01, Aadhaar-authentication guidance, query replies, through to GSTIN.
- Return filing — ₹499 per month: GSTR-1 and GSTR-3B (or QRMP equivalents), prepared from your invoice list, with a monthly summary.
- LUT filing and renewal: fixed quote in writing, and a reminder before each 31 March so an expired LUT never interrupts your export invoicing.
