Say a bank has already withheld 27.5 percent capital gains tax on dividends while a taxable Bitcoin loss arose on a crypto platform. The investor can then claim the offset through the tax return. Capital gains tax already withheld can be refunded in part as a result.

Another point carries weight: offsetting works in principle within one and the same calendar year. A Bitcoin loss from 2026 can therefore be set against dividends from 2026. An unused private capital loss generally cannot simply be carried forward into later years. That is what separates private investment income from certain business losses. Towards the end of the year it can therefore become relevant for investors which gains and losses have actually been realised.
Bitcoin losses cannot be offset against savings account interest
Not every form of investment income may be set against Bitcoin losses.
Offsetting against interest on bank deposits is explicitly ruled out. That covers classic savings account interest and certain account interest. Certain distributions from private foundations are excluded as well.
In simplified terms:
- Bitcoin loss plus dividends: possible in principle
- Bitcoin loss plus gain on shares: possible in principle
- Bitcoin loss plus other eligible crypto gains: possible in principle
- Bitcoin loss plus savings account interest: not possible
- Bitcoin loss plus salary: not possible
Tax reporting becomes more important as proof of a Bitcoin loss
For income from the 2025 calendar year onwards, Austrian entities obliged to withhold capital gains tax, such as banks and certain crypto service providers, have to produce standardised tax reporting on request.
It sets out income, losses and capital gains tax already withheld, among other items. The reporting can then serve as proof of an offset that is not applied automatically in the income tax return. Anyone holding dividends at a bank and Bitcoin on a separate crypto platform should therefore keep the tax documents from both providers.
Bitcoin gains can also be offset against losses on shares
Offsetting works in the other direction too.
Take an investor with:
- 8,000 euros of taxable Bitcoin gains
- 5,000 euros of realised losses on shares
In principle only the remaining positive amount of 3,000 euros is then subject to the corresponding taxation, provided the losses on shares may be taken into account under the loss offsetting rules. Here too, the offset between crypto income and other investment income is not applied automatically across the various providers and may have to be carried out through the income tax assessment.

Investors in Austria can in principle offset Bitcoin losses against dividends and certain other investment income. What is decisive is that the losses were actually realised and that they arise in the same calendar year as the positive income.
One thing matters above all: banks and crypto platforms do not offset Bitcoin losses and dividends against each other automatically. Anyone holding assets with different providers generally has to claim the cross-provider offset through the income tax return.
The standardised tax reporting available since 2025 is intended to help document crypto gains, losses and capital gains tax already paid to the tax office in a comprehensible way.
