Deftio: FTT done in minutes, stress-free
The Financial Transaction Tax (Slovak Act No. 279/2024 Coll.) has been in force since 1 January 2026. Deftio imports your bank statements, automatically classifies transactions, calculates the tax and generates the Notice for the Financial Administration. You just review and confirm.
Problem
Monthly FTT compliance eats hours, and a single mistake costs money. Manually going through statements, distinguishing taxable from exempt transactions, calculating rates and caps, generating XML for the Financial Administration portal. With multiple clients it becomes unsustainable. And a classification error means the wrong amount of tax paid.
How it works
From statement import to a finished Notice for the Financial Administration, in four steps.
Revolut Business, Wise Business, Slovenská sporiteľňa, VÚB, Tatra banka. Automatic format recognition, duplicate detection.
A two-stage engine sorts every transaction: taxable, cash withdrawals, internal transfers, out of scope. Unclear cases are flagged for your review. It never guesses.
Deterministic calculation under the statutory rates and caps (0.4% / 0.8%, annual card fee). A clear breakdown of the base, the tax and exempt amounts.
A PDF document plus XML valid for the Financial Administration portal. Archive per entity and period.
