German Crypto Tax 2027: Reporting Obligation and the End of the Holding Period

In July 2027, German tax authorities will receive the first automatic report containing data on every crypto trade recorded by EU exchanges in 2026. This is no longer an announcement — it is an ongoing process. While public debate focuses almost exclusively on the possible end of the holding period, a reporting system is already quietly establishing facts in the background. Anyone thinking about German crypto tax 2027 purely in terms of a possible tax rate is overlooking obligations that already apply today.

This article sorts out what is confirmed and what remains a draft, based on a recent breakdown by @thinkitcrypto from October 23, 2026.

Key Takeaways

• Since January 2026, EU crypto exchanges have been reporting transaction data to tax authorities. The first report for 2026 goes out in July 2027.
• Exchanges are asking existing customers for their tax ID and tax residency by the end of 2026. Those who don’t respond risk a trading freeze after 60 to 90 days.
• The planned abolition of the holding period starting in 2027 has not been finally decided. The cabinet vote has already been postponed multiple times.
• If purchase data is missing, the draft law states that flat-rate half of the sale proceeds could be treated as profit, regardless of the actual gain.
• Complete documentation — especially of holdings as of December 31, 2026 — is becoming the most important step investors can take.

German Crypto Tax 2027: What Is Already Confirmed

The discussion around German crypto tax 2027 is often reduced to a single question: will the holding period fall or not? But part of the reform is already running, independent of any political decision.

Reporting obligation for exchanges is already active

Since January 2026, crypto exchanges within the EU have been systematically collecting data on their users’ purchases, sales, exchanges, and transfers. This data is intended for tax authorities. The first report will be sent in July 2027, covering the entire year 2026.

In concrete terms: every transaction currently taking place on a European exchange is being logged and will later be transmitted to the tax office. Investors who believe crypto gains are hard for authorities to trace should revise that assumption.

Tax ID request is already underway

Anyone who opened their account before 2026 is currently receiving requests from their exchange for their tax ID and tax residency. Many platforms are running this request now, with a deadline of the end of 2026.

The consequence of not responding is clearly regulated: the exchange freezes trading 60 to 90 days after the first request. These emails should not be ignored or flagged as spam.

“Don’t click away the email from your exchange.” This simple rule becomes the single most important compliance task for every crypto investor in Germany in 2026.

Overview: What is confirmed, what is still a draft

German Crypto Tax 2027: What Is Only Planned, Not Decided

This is where the part of the reform that still lacks legal certainty begins. It’s important to clearly name this distinction rather than presenting plans as settled law.

The possible end of the holding period

For all crypto assets purchased from 2027 onward, the current one-year holding period would be eliminated. Profits would then be taxed at a flat rate of 26.375%, regardless of how long the coins were held.

Assets acquired by the end of 2026 would not be affected by this change. They would remain tax-free after a one-year holding period, as is currently the rule.

Crucially, however: this provision has not yet been decided. The responsible cabinet vote has already been postponed several times. Investors should treat this information as a planning stage, not as settled law. Anyone who fully bases their strategy on this assumption today is taking on risk should the timeline or shape of the reform still change.

Flat-rate profit calculation: the underestimated detail

One detail in the draft has received little public attention so far, but carries significant financial weight: if the exchange is missing an investor’s purchase data, the draft states that a flat 50% of the sale proceeds would be treated as profit.

A calculation example illustrates the impact:

• Sale price: €10,000
• Actual purchase price: €9,000
• Actual profit: €1,000
• Flat-rate taxed amount under the draft: €5,000

The difference between real and flat-rate assumed profit is substantial in this example. Without complete records, an investor would pay tax on a five-times-higher amount than they actually earned.

Why Documentation Matters More Than Any Forecast Right Now

Given the uncertainty around the final legal text, it’s worth focusing on what investors can control themselves: their own records.

What exactly should be documented

For solid record-keeping, the following details are necessary:

• Every purchase with date and price
• Every sale with date and price
• Every exchange between different cryptocurrencies
• Every transfer between an exchange and your own wallet
• Any fees incurred during transactions

Especially important is the holdings balance as of December 31, 2026. Should the planned reform actually go through, this date marks the line between old holdings that fall under the current holding-period rule and new holdings that could potentially be taxed without the holding-period benefit.

Anyone who cannot prove at that cutoff date which part of their portfolio counts as old holdings risks giving away exactly the portion that should have remained tax-free.

Two basic documentation approaches

In principle, investors have two approaches available:

Manual documentation via spreadsheet: every purchase, transfer, and fee is entered by hand into a table. This approach requires discipline and ongoing maintenance but offers full control over your own data.

Automated tracking via specialized software: certain tools capture transactions automatically and sort them into tax categories. This approach reduces manual effort but does not replace your own review of the data for completeness.

Regardless of the chosen path: responsibility for complete and correct records lies with the investor.

Takeaway: What Investors Should Draw From the Crypto Tax 2027 Debate

Coverage of German crypto tax 2027 often focuses on whether the holding period will fall or not. That’s understandable, since the possible 26.375% flat tax rate without a holding period would be financially noticeable. Still, the reporting obligation deserves at least as much attention, because it is already reality and no longer subject to political negotiation.

In summary, two categories of action can be distinguished:

1. Immediate action needed: respond to exchange requests for tax ID and tax residency to avoid a trading freeze.
2. Medium-term action needed: build a complete transaction history, especially with regard to holdings as of December 31, 2026.

Both points can be addressed regardless of how the final legislation on the holding period turns out.

Conclusion

The reform of crypto taxation in Germany consists of two clearly separate parts. The exchanges’ reporting obligation and the tax ID request are already active, ongoing processes with fixed deadlines. The possible end of the holding period and the flat-rate profit calculation for missing data, on the other hand, remain drafts that the cabinet has not yet finally decided on.

For investors, a clear priority follows: instead of focusing exclusively on forecasts about the reform, the focus should be on your own documentation. Anyone who records every purchase, every exchange, and every transfer with date and price — and in particular can cleanly document their holdings as of December 31, 2026 — is on the safe side regardless of how the reform’s political process unfolds.
