How It Works

From trade import to a complete tax calculation in three steps

1

Import your trades

Upload the Flex Query XML from Interactive Brokers or the account history from XTB. We read the trades, the dividends, the interest and the withholding tax automatically. You add or edit anything else by hand.

2

Review the calculation

We match the trades with the FIFO method, and for shares and ETFs we apply the one-year holding test and the 500 € exemption. We tax the dividends under §51e with a credit for the foreign withholding tax, and the interest and coupons under §7. You choose the ECB rate, we calculate the tax and the health contributions, and you see how every number arose.

3

Download your report

First add the unmatched trades — the lock refuses the report without them. Then you lock it and download the PDF for the annex of the Type B return. The lock is final, and the trades of that year must fit the limit of your plan.

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, interest, coupons 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 a credit for the foreign withholding tax, interest and coupons from abroad under §7 at 19 %, the sale of shares, ETFs and crypto under §8 at the progressive rate of the year (19 % / 25 % up to 2025, four bands of 19 – 35 % from 2026), plus health contributions.
