Austria Bitcoin savings plan: moving-average cost basis for taxes
Austria’s tax treatment for a Bitcoin savings plan uses a moving-average purchase price (cost basis) when calculating taxable gains. Under the rule, multiple Bitcoin purchases at different prices are merged into one average cost only for the same relevant reference unit—typically the crypto address or wallet where the coins are held. The example given: buying 0.01 BTC for €300, then 0.01 BTC for €400, then 0.01 BTC for €500 results in a total acquisition cost of €1,200 for 0.03 BTC, implying €40,000 per BTC. If later selling 0.01 BTC, Austria attributes €400 of acquisition cost to that sold portion regardless of whether it was bought first or last.
Each new Bitcoin savings plan purchase shifts the average price for future sales, and the same approach applies for both capital gains deduction and income tax assessment. Investors using multiple wallets may face different cost bases because wallets/addresses can carry separate moving-average prices for tax purposes. A key exception applies to “legacy” Bitcoin acquired up to and including 28 Feb 2021 (and certain holdings with flat-rate acquisition costs due to missing tax data): those are treated separately from newer moving-average lots.
Tax generally arises on realization (e.g., when Bitcoin is sold for euros), not on the savings-plan purchase itself. For Bitcoin acquired after 28 Feb 2021, realized gains are stated as generally taxed at 27.5%, and the article notes holding period is not decisive.
Neutral
This is primarily a tax-cost-accounting clarification for Austria’s Bitcoin savings plan, not a change to Bitcoin’s protocol, supply, or market structure. For traders, the main relevance is how realized gains are computed: using a rolling moving-average cost basis can change the timing and magnitude of taxable gains when selling from multiple buys. In the short term, this may influence trader behaviour around partial profit-taking or rebalancing (e.g., deciding which wallet/address to sell from), but it should not directly affect BTC liquidity or fundamentals.
In the long run, consistent cost-basis rules tend to reduce uncertainty for compliant investors and may support steadier DCA participation in Austria. The biggest market-adjacent implication is behavioural: if investors realise they can’t “cherry-pick” low-cost lots (because moving average applies), they might delay sales or increase record-keeping, which can slightly dampen sell pressure. Similar cost-basis and lot-tracking regimes in other jurisdictions have historically led more to portfolio-management shifts than to broad market moves. Therefore, expected market impact is neutral.
