Supported brokers and kloPIT features

kloPIT is a PIT-38 calculator for investors using foreign brokers. It works best with dedicated import parsers, but you can also enter transactions, dividends and carry-in positions manually.

When a broker has no parser

You can still use kloPIT by adding transactions, dividends and withholding manually on the Data page. This is a practical path for smaller accounts or brokers waiting for a dedicated importer.
