Interactive Brokers Fees and Taxes in Germany
Last updated:
JulianAnyone using Interactive Brokers will sooner or later encounter a practical question that often causes uncertainty in the German tax return: How are fees at IBKR to be treated for tax purposes? This concerns not only standard order costs, but also special items such as ADR fees, interest on margin loans, market data fees or other ongoing broker costs.
Note: KapitalTax assists with the structured preparation of Interactive Brokers data for the German tax context. The content on this page and the analyses provided by KapitalTax are for general information and preparation purposes only and do not constitute individual tax or legal advice. Whether and how individual values are to be considered in a personal tax return depends on the individual case.
Especially with a foreign broker like Interactive Brokers, this question is important because no German tax certificate is provided that already classifies such topics for the German tax context. Instead, users must understand themselves which fees reduce the taxable income, which only reduce the net inflow, and which are generally not separately deductible for private investors.
This page covers the tax treatment of typical fees at Interactive Brokers in Germany – focusing on ADR fees, margin interest, ongoing broker fees and the important distinction between non-separately deductible ongoing costs and transaction costs at the acquisition or disposal level.

Why fees at Interactive Brokers are often unclear for tax purposes
Many users see various charges in the Activity Statement from Interactive Brokers that look similar at first glance: fees are deducted from the account and reduce the account balance. However, for tax purposes, it is necessary to distinguish what type of expense is actually involved.
In the German tax context, the following distinction is particularly important:
- ongoing administrative and broker costs
- transaction costs for buying or selling
- special charges related to dividends or ADRs
- interest on borrowed capital, e.g. when using margin
This distinction is crucial because not every fee has the same tax effect. For private investors, an important basic principle applies: ongoing costs of asset management, account maintenance or financing are generally not additionally deductible as expenses for capital income. Transaction costs are to be distinguished from this.
Basic rule: Not every IBKR fee is to be treated the same for tax purposes
When it comes to fees at Interactive Brokers, one should fundamentally distinguish between two groups.
The first group consists of ongoing fees, i.e. costs for custody, account maintenance, data provision or financing. While these economically reduce your result, they are generally not additionally separately deductible for private capital income.
The second group consists of transaction costs, i.e. costs that are directly related to the acquisition or disposal of a specific security or derivative. Such costs can be relevant at the level of acquisition or disposal costs for tax purposes and are therefore to be treated differently from ongoing broker costs.
Especially at Interactive Brokers, this distinction is important because Activity Statements show many different types of fees side by side. For the tax analysis, therefore, it is not only the amount of a fee that matters, but above all its economic context.
ADR fees at Interactive Brokers
A particularly common question at Interactive Brokers concerns ADR fees. These fees arise for certain American Depositary Receipts and are charged by the responsible custodian banks or depositary agents. Interactive Brokers passes such charges on to the account holder.
How ADR fees are to be classified in Germany
For private investors in Germany, ADR fees are tricky from a tax perspective because they are neither capital gains tax nor withholding tax. Rather, they are economically to be understood as administrative or custody costs in connection with the ADR holding.
This means in practice:
- The ADR fee is not creditable against German flat-rate withholding tax (Abgeltungsteuer)
- It is not a foreign tax
- It economically reduces your net inflow or charges your account separately
- For private capital income, it is typically not separately deductible
Example of the practical effect
If an ADR distributes a dividend of USD 1.00 and an additional USD 0.02 ADR fee is charged, you economically receive only USD 0.98 net. However, for tax purposes, the ADR fee is not withholding tax and not a creditable tax, but a fee. The relevant starting amount is therefore generally the gross dividend of USD 1.00. This USD 1.00 is the tax-relevant starting amount; the USD 0.02 ADR fee reduces the net inflow but is not creditable against the flat-rate withholding tax. At the same time, for private investors they generally cannot be deducted separately, as such costs in the capital area are generally already covered by the saver's lump sum. This is exactly why ADR fees are often confused with withholding tax by IBKR users, even though both items do not have the same function for tax purposes.
Interest on margin loans at Interactive Brokers
Another common topic is interest on margin loans, i.e. interest on borrowed capital used through Interactive Brokers' margin account. Economically, these are financing costs. For private investors in the area of capital income, such margin interest is generally not additionally deductible as separate expenses. While they economically reduce the result, they generally cannot be claimed separately for tax purposes, as such expenses in the area of capital income are generally already covered by the saver's lump sum. This is exactly why margin interest is a common question among IBKR users: it clearly appears in the Activity Statement as a charge, but is not treated as a creditable tax position for tax purposes.
Ongoing broker fees and market data fees
In addition to ADR fees and margin interest, there are other recurring costs at Interactive Brokers, for example:
- market data subscriptions
- other account maintenance or service fees
- custody or administrative charges
For private investors, the same basic principle applies here: such ongoing costs are generally not additionally deductible for income from capital assets. They therefore cannot be claimed separately in the tax return, as such expenses in the capital area are generally already covered by the saver's lump sum. For private individuals, these fees are therefore an economic burden, but generally not a separate tax deduction item.
Transaction costs are different from ongoing fees
It is important to distinguish transaction costs. Not everything that appears as a "Fee" or "Commission" at IBKR is automatically to be treated like an ongoing administrative fee.
Costs that are directly related to the purchase or sale of a specific security or derivative can be relevant at the level of acquisition or disposal costs. These include, for example, typical order costs or transaction-related ancillary costs of a specific trade such as transaction taxes.
Especially at Interactive Brokers, this distinction is important because the reporting shows many different types of fees side by side. For the tax analysis, therefore, it is not just the name of the fee that matters, but its actual function in the respective transaction.
Fees for options: different classification than pure administrative costs
For options, the classification is even more specific. Users of Interactive Brokers frequently trade not only stocks and ETFs, but also options. Fees and ancillary costs in this area are therefore not simply to be equated with market data fees, ADR fees or other ongoing broker costs.
Especially for options, it depends on whether a cost item is part of a specific options transaction. Transaction-related ancillary costs can be classified differently for tax purposes than pure ongoing service or administrative costs.
In practice, this means:
- ongoing broker costs are different from
- transaction-related costs of a specific options transaction
Therefore, a good tax preparation of IBKR data should not treat fees across the board, but distinguish them according to their tax function.
