How do freelancers and consultants stay GST-compliant in India — invoicing, returns and the LUT?

A GST tax invoice is mandatory for every taxable supply. Missing or incorrect invoices block your client's input tax credit claim and attract scrutiny.

Mandatory fields on a GST invoice:

(1) Your name, address and GSTIN;
(2) Invoice number — consecutive, unique for each financial year; must not be repeated;
(3) Invoice date;
(4) Client name, address and GSTIN (for B2B supplies — client's GSTIN is essential for their ITC);
(5) Description of service — specific enough to identify the SAC (Services Accounting Code); common codes for freelancers:
(a) SAC 998314 — software and IT consulting;
(b) SAC 999294 — content writing, editing;
(c) SAC 998361 — management consulting;
(d) SAC 999000 — other professional services;
(6) Taxable value (your fee before GST);
(7) GST rate and amount — most freelance services attract 18% GST; split as CGST 9% + SGST 9% (intra-state) or IGST 18% (inter-state or to foreign client);
(8) Total invoice value (fee + GST);
(9) For export / foreign client invoices: add 'EXPORT OF SERVICES — ZERO RATED SUPPLY' and your LUT ARN number;

Invoice timing: issue within 30 days of completing the service (45 days for banking and financial services).

Revised invoice: if you need to correct an invoice, issue a Credit Note (reduces value) or Debit Note (increases value) — never alter the original.

Two core returns for most freelancers:

(1) GSTR-1 — outward supplies (invoices you issued):
(a) Lists every invoice issued in the period;
(b) Monthly filers (turnover > ₹5 crore): due by 11th of the following month;
(c) Quarterly filers under QRMP: due by 13th of the month after the quarter;
(d) Filed on the GST portal (gst.gov.in);

(2) GSTR-3B — monthly summary return:
(a) Summary of outward and inward supplies, GST liability and ITC claimed;
(b) Monthly filers: due by 20th of the following month;
(c) QRMP quarterly filers: due by 22nd or 24th of the month after quarter (varies by state);
(d) Tax must be paid when filing GSTR-3B;

(3) QRMP scheme (Quarterly Return Monthly Payment):
(a) Available if annual turnover ≤ ₹5 crore;
(b) GSTR-1 and GSTR-3B filed quarterly;
(c) But tax is paid monthly through a fixed-sum installment (IFF - Invoice Furnishing Facility for first 2 months);
(d) Significantly reduces compliance burden for small freelancers;
(e) Opt in through the GST portal at the start of a quarter;

(4) GSTR-9 — Annual return:
(a) Due by 31 December of the following year;
(b) Optional for turnover ≤ ₹2 crore;
(c) Mandatory above ₹2 crore;

(5) Late fees: ₹50/day (₹25 CGST + ₹25 SGST) for GSTR-1 and GSTR-3B; ₹20/day for nil returns; maximum capped at ₹10,000 per return.

If you provide services to clients outside India (software development, content writing, design, consulting), your supply qualifies as export of services — which is zero-rated under GST.

(1) Without an LUT: you must charge 18% IGST on your invoice to the foreign client, then claim a refund from the GST department — slow and cash-flow-unfriendly;

(2) With an LUT: you invoice the foreign client at zero GST (₹0 GST) and receive payment in foreign currency; no upfront GST outlay;

(3) Conditions for zero-rated export:
(a) The service is supplied to a person outside India;
(b) Payment is received in convertible foreign exchange (USD, GBP, EUR etc.);
(c) The service is not a service provided to a branch/agent in India;

(4) Filing the LUT:
(a) File Form RFD-11 (LUT application) on the GST portal;
(b) Annual — must be filed at the start of each financial year (1 April);
(c) On approval, an ARN (Application Reference Number) is generated — quote this on all export invoices;
(d) No fee; processing is typically automatic (system-generated ARN);

(5) Ineligible if: you have been prosecuted for tax evasion above ₹2.5 crore in the past; LUT requires pre-qualification.

(6) Bond vs LUT: most freelancers qualify for LUT (no bond or deposit required); only ineligible exporters need to furnish a bond with surety.

Yes — GST-registered freelancers can claim Input Tax Credit (ITC) on business expenses, reducing their net GST liability:

(1) Eligible ITC: GST paid on goods and services used for your taxable supplies:
(a) Laptop, equipment, software subscriptions;
(b) Internet and phone (business proportion);
(c) Office rent (if GST-registered landlord);
(d) Professional subscriptions, courses;
(e) Accounting software, GST filing tools;
(f) Subcontractor services (if they are GST-registered);

(2) Ineligible ITC (blocked under Section 17(5) CGST Act):
(a) Food and beverages, outdoor catering;
(b) Club memberships, health and fitness;
(c) Personal travel;
(d) Motor vehicles (unless you're in the business of transport);

(3) Conditions for claiming ITC:
(a) Supplier has filed their GSTR-1 and the invoice appears in your GSTR-2B;
(b) You have a valid tax invoice;
(c) You have received the goods/services;
(d) Tax has been paid to the government by the supplier;

(4) Reverse Charge Mechanism (RCM): if you receive services from an unregistered vendor above threshold, you must self-assess and pay GST under RCM and then claim ITC on the same.
