| Inflow | Often a taxable receipt |
|---|---|
| Cost basis | Market value at inflow, or a full gain later |
| Dust / scam | No market usually means no amount to book |
Distinguish unsolicited credits from rewards for use, sign-up or lock-up. The Ministry of Finance looks for a service. Unsolicited airdrops with no consideration are often still documented with an inflow value out of caution. What matters is a traceable valuation, not omitting the coins.
You receive a new coin without selling the old one. The new coin needs an accrual date and a value. The old coin keeps its existing history. If you ignore the fork, a later sale has no origin.
Many dust and scam tokens have no serious market. Do not book those as a valuable inflow. Genuine airdrops need a price. In CleanUp you separate worthless credits from real rewards before they distort the report.
Worthless or fraudulent tokens with no market are generally not a relevant inflow. Document why you do not recognise them instead of selling them at fantasy prices.
At accrual. A later sale tests the period from that date, not from the purchase of the original coins.
Usually not. You do not give up the old coin. It is an additional inflow next to the continuing old holding.
This guide structures the data issues and common German administrative practice. It is not tax advice. The assessment in your case stays with you and your tax advisor.
Record airdrops and forks with date and price. Otherwise you later sell with cost basis zero.
