Why one year per run, from the start

Slovenia requires FIFO: each sale is matched against your oldest purchase of the same security. A Flex Query run covers at most 365 days, so a single export for the tax year leaves out older purchases, their cost basis becomes zero and the tax is overstated. Run the query once for each calendar year since you opened the account and upload all files together.

Step 1: Open Flex Queries

1. Log in to Client Portal

2. Go to Performance & Reports → Flex Queries

Step 2: Create an Activity Flex Query

1. Click + next to Activity Flex Query and give it a name

2. Under Sections, enable Trades

3. Keep the Asset Class field. It is how options, futures and CFDs (D-IFI) are separated from shares and ETFs (Doh-KDVP); without it everything is treated as securities

4. Under Delivery Configuration choose CSV (XML is not supported)

5. Set the Date Period to one calendar year, e.g. 2024-01-01 to 2024-12-31

6. Save, Run and download the CSV. Repeat for every year since the account was opened

On some CapTrader accounts a full-year run returns an error. Export shorter periods, for example by quarter, and upload them all; duplicate rows are recognised and skipped.

Step 3: Upload and download the XML

The app itself is in Slovene; button names are given with a translation.

1. Open Uvoz podatkov, “Import data”, and drop all CSV files at once

2. At the top of the app choose the Davčno leto, “Tax year”

3. Open Dokumenti za eDavki, “Documents for eDavki”

4. Click Prenesi XML, “Download XML”, for Doh-KDVP and, if you traded derivatives, D-IFI

What is imported, and what is not

Imported: purchases and sales of securities (Doh-KDVP); options, futures and CFDs are recognised by Asset Class and placed on D-IFI. Not imported from the IBKR export: dividends, foreign withholding tax, interest, corporate actions (splits, spin-offs, mergers), forex and crypto. Dividends and interest are in separate Flex Query sections that are not read; handle them manually or with a tax adviser.

Then import each XML into eDavki; the portal steps are in How to file in eDavki. All forms are due by 28 February for the previous year.

FAQ

Does IBKR Lite or Pro make a difference?

No. Both have the same Flex Query reports.

IBKR reports in USD. Will the conversion be right?

Yes. Every value is converted to euros at the ECB reference rate for the date of the transaction.
