File 25+ Client Returns Before 30 November — Without the Spreadsheet Chaos

In short

LankanTax for Accountants is practice software for Sri Lankan tax practitioners managing 25 or more clients: one roster for every client’s income data, automatic Y/A 2025/26 computations and IRD schedules, deadline tracking against the 30 November return date, and — on the hosted edition — multi-user access and one-click field-filling on the IRD e-services portal via our Chrome extension. Rs 15,000 covers your first 25 filings; Rs 1,000 per filing after that.

Built for the season crunch

Every client, one roster. Each client’s income data, status and documents in one place — no more one-spreadsheet-per-client folders.
Computation you can defend. Band-by-band workings per client, APIT/AIT credits, the 15% remitted-FX cap, rent standard-vs-actual options — printable for the client file.
Deadline cockpit. Quarterly instalments (15 Aug · 15 Nov · 15 Feb · 15 May) and the 30 November return date tracked per client — the same dates as our public deadlines calendar.
Filing at speed. On the hosted edition, the Chrome extension fills each client’s IRD e-services return from your prepared data — you or the client reviews and submits. On the desktop edition you get a guided field-by-field fill instead.
Choose where client data lives. Two deployment options, stated plainly: the desktop edition keeps all client data on your office computers (backups to your own cloud drive); the hosted edition runs online, which is what enables multi-user access and extension autofill. You pick the trade-off — we don’t hide it.

Frequently asked

Practice questions, answered.

How is this different from TaxWise? +

Three factual differences: LankanTax for Accountants is priced per filing (Rs 15,000 for 25, then Rs 1,000 each) rather than per year; it offers a desktop option that keeps client data entirely on your office computers; and its hosted edition fills the IRD e-services fields via Chrome extension. TaxWise is cloud software with annual plans — a good product; compare both against your practice's needs at lankantax.com/best-tax-software-sri-lanka/.

Can clients review before submission? +

Yes — nothing is submitted by the software. You (or the client, on their own IRD login) review every field on the official e-services portal and submit there. The IRD issues the acknowledgment.

Do you see our client data? +

On the desktop edition: no — client data lives on your office computers and your own backups; we have no server access to it. On the hosted edition, data is stored on our servers to enable multi-user access and extension autofill; it is used only to provide the service. Choose the edition that matches your confidentiality posture.
