Switching crypto exchange: what happens to the holding period and the tax when you transfer

Anyone sending their coins from one trading platform to another, or to their own wallet, loses neither the holding period nor triggers a tax. A transfer between addresses that belong to you is not a disposal, because nobody pays anything for it and the asset does not change owner. The one-year period of Section 23 of the German Income Tax Act keeps running without interruption.

The switch still gets expensive, just in a different place: the acquisition data breaks off during the transfer. The new platform does not know when you bought and at what price. Anyone not securing that beforehand faces, come the following spring, a holding with no provenance and has to explain to the tax office why the holding period is supposed to have elapsed. This article shows you what really happens for tax purposes, where the wallet-based approach bites, and which records to pull before you hit send.

Switching exchange: what the transfer triggers for tax

The short answer: nothing. Neither on sending nor on arrival does a taxable event arise, as long as sender and recipient are the same person. That follows directly from the structure of the private disposal transaction.

In its circular of March 6, 2025 on individual questions of the income tax treatment of certain crypto assets, the German Federal Ministry of Finance describes in margin number 54 what an acquisition and what a disposal is. An acquisition is the acquisition from third parties for consideration. Mirroring that, the transfer of the acquired asset to third parties for consideration constitutes a disposal. Both features are absent in a transfer to your own address: there is no third party, and no consideration flows.

Under the same margin number, a disposal arises from the exchange of crypto assets into units of a state currency such as the euro, into goods or services, and into other crypto assets. That is exactly where the distinction that matters lies. Anyone sending Bitcoin from one platform to the next has exchanged it for nothing at all. Anyone switching into a different coin along the way has sold.

Why the blockchain entry is not the moment that counts for tax

A widespread misunderstanding holds that every movement on the blockchain is relevant for tax because it is publicly visible. In margin number 20 the ministry expressly clarifies that the recorded inflow and outflow of crypto assets need not coincide with the acquisition or disposal date relevant for income tax.

The same margin number supplies the background: crypto assets are regularly traded via central trading platforms, being first transferred to the platform's personalised account and only booked back into the user's own wallet at a later point. What is then decisive is the time of the trade via the platform, not the time of the booking. The same applies where you use no wallet of your own at all and hold and trade exclusively via a platform.

For a change of platform that means: the deposit booking on the new exchange is not an acquisition date. Your acquisition date remains the day on which you originally bought the coins, and that holds even where the new platform's tax report claims otherwise.

The holding period keeps running: what that means for your year

Under Section 23 (1) sentence 1 no. 2 of the Income Tax Act, a private disposal transaction in other assets is taxable where no more than one year lies between acquisition and disposal. Once that year has elapsed, the gain remains tax free, no matter its size.

Because the transfer is not a disposal, it does not reset that period. An example makes it tangible. You buy coins on platform A on February 4. On September 20 you send them to platform B, and on December 3 onward to a hardware wallet. If you sell on February 10 of the following year, the sale falls outside the one-year period and the gain remains tax free. February 4 is the only date that counts.

Within the one-year period the threshold of Section 23 (3) sentence 5 of the Income Tax Act applies on top: gains from all private disposal transactions of a calendar year remain tax free if their total comes to less than 1,000 euros. Up to and including the 2023 assessment period this limit stood at 600 euros. Here too: once the amount is reached, the entire gain is taxable.

Ten-year holding period: why the extension does not bite with coins

A stubborn rumour says that anyone lending out their coins or earning income with them extends the holding period from one year to ten. That worry keeps many from moving their holdings at all.

Margin number 63 of the BMF circular clears it up: with currency or payment tokens, the extension of the disposal period under Section 23 (1) sentence 1 no. 2 sentence 4 of the Income Tax Act does not apply. The tax authorities took that position in the predecessor circular already and confirmed it in March 2025. For the common coins it therefore stays at one year, even where income was earned in the meantime.

The real trap: the wallet-based approach

If the transfer itself is harmless, why all the care? Because the ministry prescribes how it is to be determined which coins you actually sold. And that rule is tied to the individual wallet.

Individual identification comes first

Margin number 61 names the principle: for determining the order of use of the crypto assets disposed of, individual identification applies. So where you can attribute precisely which unit you bought when and sold again when, that is the governing route.

Where individual identification is not possible, the crypto assets of a trading designation acquired first are deemed to have been disposed of for the purposes of the holding period, and for the valuation the average method is to be applied. The ministry relies here on a judgment of the Federal Fiscal Court of November 24, 1993. For reasons of simplification it may be assumed for the valuation that the crypto assets acquired first were disposed of first, in other words the familiar FiFo method.

Where the wallet boundary runs

Then comes the sentence that becomes decisive when changing platform: a wallet-based approach applies. Within a wallet the chosen method must be retained until all crypto assets of that trading designation in that wallet have been disposed of in full. Only after a complete disposal and a subsequent fresh acquisition may the method be changed. Where crypto assets with differing trading designations are held via one wallet, a separate election exists for each.

In practice that means: spread the same coin across three addresses and you have three separate accounting circles. The order of consumption is not formed across your total holding, but per wallet. Anyone shifting holdings back and forth builds themselves a set of books that can later only be reconstructed with software and complete exports.

What really gets lost in the transfer: the acquisition data

A trading platform knows only what happened on it. When a holding arrives from outside, it sees a deposit with no prior history. Purchase price, purchase date and the order of consumption applied so far do not travel with it.

The ministry has seen this problem. On the plausibility of tax reports, margin number 90 states that adjustments and corrections do not as a rule stand in the way of plausibility where they are marked as such and substantiated comprehensibly, expressly naming as an example: because of missing acquisition costs or acquisition data on transfers to other trading platforms.

That is a relief with a condition. You may add the data later, but you have to mark the correction and be able to substantiate it. Without documents from the old platform only an estimate remains, and an estimate rarely falls in your favour. A tax tool only helps if you feed it the exports from both platforms; an overview of the providers is given by our comparison of crypto tax tools and portfolio trackers.

What to download before you send

Pull the complete transaction export from the old platform as a structured file, not as a PDF. That includes all purchases with date, quantity and price, all sales, all fees, and the withdrawal itself with transaction hash and destination address. Also secure the balance at year end: margin number 104 expressly names wallet holdings on key dates such as December 31 of the assessment period and of the previous year as details the tax authority can request.

The reason for the haste is mundane. Platforms close accounts after inactivity, withdraw from regions or disappear altogether. The export you pull today with two clicks can be a support case in a foreign language two years from now.

The special case: when the switch is a sale after all

Three variants of a platform change are taxable events after all, and to the user they look almost exactly like a harmless transfer.

The detour via a stablecoin. Anyone selling the coin on the old platform, transferring the proceeds as a stablecoin and swapping back on the new platform has triggered two disposals. Both exchanges are disposals under margin number 54, and the holding period starts afresh for the repurchased holding.

The change of wrapper. Where a coin is swapped into a wrapped variant or a network representation during the transfer, an exchange into a different crypto asset regularly exists. Whether asset identity holds in the individual case is a question of the specific design, and in case of doubt the tax authorities will assume an exchange.

The sale on delisting. Where a platform removes an asset from trading and you sell at short notice instead of transferring, that is an entirely ordinary sale with all its consequences. How tight those windows can be is something our editorial team worked through using the example of transferring delisted tokens to a fallback exchange.

Network, fees and minimum amounts: the technical part

The tax side is one half. The other is the transfer itself, and that is where the losses happen that can no longer be corrected.

The network first, then the address

The same coin often exists on several networks, and the address formats look confusingly alike. Anyone sending to the wrong network gets their balance back at best after a support case, and at worst not at all. So check first which network the destination platform supports for that asset, and select it explicitly on the sending side. Which mistakes happen most often is shown in our article on why the wrong network when sending so frequently leads to total loss.

The test transfer

Send a small amount first, wait for it to be credited, and only then send the rest. The double network fee is the cheapest insurance premium you can pay in this context. Watch the minimum withdrawal amount on the sending side and the minimum deposit amount on the receiving side, because amounts below the threshold vanish without comment into the accounting on some platforms.

What transaction fees are for tax purposes

Fees incurred on purchase form part of the incidental acquisition costs. Transaction fees expended in connection with a disposal are to be taken into account as income-related expenses under margin number 59. The plain network fee for a transfer between your own addresses, by contrast, is attributed to neither event, because nothing is bought or sold in between. Record it all the same, so that your holding adds up arithmetically after the transfer.

Where you also change the type of custody

Many change platform not because of the fees, but because they want to get their holdings off a platform altogether. That step markedly changes the legal position in the event of insolvency, because with self-custody you hold the keys yourself and depend on no segregation claim.

For tax purposes what was said above still holds: the route to a hardware wallet is also a transfer without consideration and without a third party. What changes is the evidence. On a platform the history sits in the account; with self-custody it sits with you. From that day on you are the bookkeeping yourself, and margin number 103 expressly requires documentation of reallocations within wallets for the wallet-based application of the average or FiFo method.

The checklist for the switch

Work through the points in this order and nothing gets left behind.

1. Pull the complete transaction export from the old platform as a structured file and store it outside the platform.
2. Note the year-end holdings of the assets concerned, for the current and the preceding year.
3. Match the network on both sides and check the minimum amounts.
4. Send a test transfer, wait for it to be credited, then transfer the rest.
5. Record the transaction hash, destination address, date and network fee of every transfer.
6. Document the chosen order of consumption for the new wallet and do not change it again while a holding of that trading designation sits there.
7. Reconcile the holding after the transfer against the export before the old platform is closed.

Switching exchange and the holding period: what to take away

The transfer costs you neither tax nor holding period. It costs you traceability if you trigger it unprepared.

1. Secure the history before you send. The old platform's export is the only evidence of when you bought. Without it you cannot demonstrate that the one-year period has elapsed. Which platforms deliver usable exports is shown in our exchange comparison.
2. Keep the order of consumption per wallet and stick with it. The wallet-based approach is not a recommendation but the requirement from margin number 61. A tax tool calculates that cleanly if you read in both sides, see our comparison of tax tools.
3. If you are moving anyway, move properly. Holdings you intend to keep for more than a year belong at an address whose keys you control yourself. Which devices are suitable for that is set out in our hardware wallet comparison.
