How It Works

From trade import to a complete tax calculation in three steps

1

Import your trades

Upload a Flex Query XML from Interactive Brokers or the account history from XTB. Trades, dividends and withholding tax are read automatically – and you can add or edit individual trades by hand at any time.

2

Review the calculation

Trades are matched using FIFO, the one-year holding test and the €500 exemption are applied, and we calculate your taxable base, tax and health-insurance contributions – itemised so you can see where every number comes from.

3

Download your report

Lock the calculation and download the PDF to use when completing your type-B tax return.

Everything you need

One tool for all your investment tax obligations

Import from broker platforms

Upload a Flex Query XML from Interactive Brokers or the account history from XTB – trades, dividends and withholding tax are read automatically. Anything else you can add by hand.

ECB exchange rates automatically

Under §31 you choose whether trades are converted at the ECB (NBS) reference rate on the transaction date, or at the annual average rate. We fetch the rates automatically.

Calculated under Slovak law

Dividends under §51e at 7% with foreign withholding tax credited, sales of stocks, ETFs and crypto under §8 at 19% / 25%, plus health-insurance contributions.
