Aktieindkomst: how share gains are taxed

Capital gains from shares listed on a regulated market (børsnoterede aktier) — as well as dividends from those shares — are classified as aktieindkomst and taxed at:

• 27% on aktieindkomst up to DKK 61,000 per year (2024 threshold for individuals)
• 42% on aktieindkomst above DKK 61,000

For married couples, the threshold is effectively doubled to DKK 122,000 combined. The threshold adjusts annually. All investment income is reported to Skattestyrelsen via Skat.dk, and Danish brokers pre-fill much of this data automatically.

Aktiesparekonto: lower rate for regular savers

The Aktiesparekonto is a tax-advantaged account where gains are taxed at a flat 17% rate — significantly lower than the standard 27%/42% structure. For 2024, the maximum cumulative deposit allowed was DKK 135,900 (limit adjusts annually). The account is available to Danish residents aged 18 and over, offered through most Danish banks and brokers.

ETFs and investment funds: different rules apply

Not all funds are treated as aktieindkomst. Investment funds classified as investeringsselskaber (investment companies) by Skattestyrelsen are instead taxed as kapitalindkomst (capital income), which is taxed at personal income tax rates that can reach 37-42% depending on total income. This distinction is important: the same ETF may be treated differently depending on its Danish tax classification. Always check the specific fund's classification at Skat.dk before investing.

Crypto in Denmark

Cryptocurrency in Denmark is generally taxed as personlig indkomst (personal income) rather than aktieindkomst, which can result in significantly higher rates — potentially up to approximately 56% including local (kommunal) taxes. The rules for crypto are evolving; for current and authoritative guidance, consult Skat.dk directly.

Paper trading: no tax implications

Paper trading with virtual money generates no real transactions and therefore no taxable events under Danish tax law. Platforms like TRION operate in 100% simulation mode — no actual securities are bought or sold, so nothing needs to be reported to Skattestyrelsen.

Important: verify with Skattestyrelsen

The DKK 61,000 aktieindkomst threshold and the aktiesparekonto deposit limit change annually. This article is informational only and does not constitute tax advice. For current rates and classification of specific funds, consult skat.dk or a licensed Danish tax adviser.

TRION was built around an honest validation sequence rather than a promise. It is a paper-only research and validation workstation: you describe a strategy idea in plain English, read the compiled logic line by line, and backtest it against real stored market data. When a metric cannot be computed honestly, TRION shows "N/A" instead of inventing a number.

TRION does not place real orders, does not connect to a broker, and does not promise profit. The current beta is simulation-only and paper-only. AI assists with drafting and explanation; it does not approve, activate, or execute anything. Humans make every decision.
