Freelancers tend to land in one of two camps. The first keeps nothing — income arrives, gets spent, and April becomes a frantic reconstruction from bank SMS alerts. The second overcorrects and hoards everything, photographing every Swiggy bill in the belief that it all somehow reduces the tax. Both are working harder than they need to, and both are missing the one decision that actually determines how much tracking they should be doing.
That decision is whether you're on presumptive taxation or not. Get that right and most of the rest falls into place. This post is the practical map: what to track, what to skip, and where GST quietly changes the picture for people who didn't think it applied to them.
A quick note: this is plain-language guidance, not a substitute for a CA who knows your specific numbers.
One decision first: presumptive, or not?
Here's the fork, in two lines. If you're a specified professional — and "specified" is doing real work in that sentence — earning under the presumptive limit, you can declare a flat 50% of your gross receipts as income under Section 44ADA and largely stop tracking expenses for income-tax purposes. If you're not eligible, or your real expenses are high enough that declaring 50% would make you overpay, then you're tracking expenses properly and claiming them the normal way.
That's the gate. The full mechanics — who counts as a specified professional, the exact limits, what happens to your bookkeeping obligations — deserve their own treatment, and I've put them in a dedicated post: do you even need to keep every receipt under Section 44ADA. For now, just know which side of the fork you're on, because everything below depends on it.
And one thing that catches people: GST is a separate question entirely. Being on presumptive tax for income simplifies income tax. It does nothing for GST.
GST is its own track
This is the part freelancers underestimate, usually right up until a client asks for a GST invoice.
You're required to register for GST once your turnover crosses ₹20 lakh for services in most states (it's ₹10 lakh in the special-category states — Manipur, Mizoram, Nagaland, Tripura). That threshold is measured on aggregate turnover across your PAN, all-India — not per client, not per city. So the consulting you do on the side counts toward the same threshold as your main freelance income.
Two wrinkles hit freelancers specifically:
- Exporting services — billing overseas clients, getting paid in foreign currency — is treated as a zero-rated supply. You can register and supply under a LUT (Letter of Undertaking) so you don't have to charge IGST, and you can claim a refund of eligible input tax credit. But the registration threshold logic still applies, and the paperwork around foreign receipts is real.
- B2B clients may want you registered even below the threshold, because your GST invoice lets them claim input tax credit. Voluntary registration is a legitimate choice if most of your work is for registered businesses.
Once you're registered, the receipts question changes shape: now the tax invoices on your business purchases can earn you input tax credit — but only if they meet GST's conditions and match what your suppliers filed. That's a whole topic on its own, and I wrote it up in a receipt isn't a tax invoice. The short version: a bare receipt isn't claimable; a proper tax invoice with your GSTIN is.
What to actually track
Strip away the anxiety and there are really two streams.
Income — always, no matter which side of the fork you're on. Every invoice you raise, every bank credit, every foreign remittance. This is non-negotiable, because:
- Your clients are often deducting TDS (typically under Section 194J for professional fees) before paying you. That shows up in your Form 26AS / AIS, and at filing time you'll want your own income records to reconcile against it — mismatches here are a common source of notices.
- If you owe more than ₹10,000 in tax for the year, you're liable for advance tax. For most freelancers that's four installments across the year (15 June, 15 September, 15 December, 15 March). Presumptive filers get a simpler deal — that's covered in the 44ADA post. Either way, you can't estimate what you owe without knowing your income as you go.
Expenses — only if you're off presumptive, or GST-registered. If you're claiming actual expenses for income tax, or claiming ITC under GST, then you need the supporting documents — and for GST, proper tax invoices, not bare receipts. If you're on presumptive and not GST-registered, obsessively tracking expense receipts buys you very little on the income-tax side.
Records worth keeping regardless
Even the minimalist should hold on to a short list:
- Bank statements for the business — ideally a separate account, so personal and business flows don't tangle.
- Invoices you raised — your own record of income, independent of what hit the bank.
- Major expense proofs — the laptop, the software subscriptions, anything you'd want to defend if asked.
- Foreign remittance documentation if you bill overseas — your bank's FIRC / inward-remittance advice and eBRC. These matter for proving export of services and for any GST refund.
A useful filing tip carried over from running any business: the law accepts digital copies, as long as they're complete, legible, and — the load-bearing word — retrievable. A clean, searchable archive beats a phone gallery of 2,000 unnamed screenshots, every time.
A system for one person
You don't need accounting software built for a finance team. You need three habits:
- One business bank account. Route client payments and business spends through it. This single move makes income tracking almost automatic and keeps your books from commingling with your groceries.
- Capture as you go. Photograph or save each invoice the moment it happens — the one raised to a client, and the tax invoice on anything you'll claim. Tag it with a word about what it was. Five seconds then saves an hour in April.
- A 30-minute monthly reconcile. Once a month, match your captured records against the bank, check TDS in your AIS, and — if you're GST-registered — reconcile purchase invoices against your GSTR-2B. If your accountant works in Tally, this is also the moment to hand off the month's expenses without retyping them. Small and regular beats heroic and annual.
That's genuinely the whole system. Capturing income and the receipts that matter, in one place you can search later, is most of what Starlog does for the solo operator — it files each capture to your own Google Drive and keeps it ready for your accountant. But the habits above work with a notebook and a folder too. The point isn't the tool; it's that the right records exist, in a findable place, before you need them.
