Why LankanTax instead of a cloud tax service?
Most tax tools ask you to upload your salary, bank interest, and client records to someone’s server. LankanTax Desktop was built on one rule: your income data is nobody’s business but yours. It runs offline, stores everything locally, and backs up encrypted to your own cloud drive. (Practices that prefer a managed setup can choose the hosted accountants edition — and that choice is yours, stated plainly, not hidden.)
