Deemed acquisition cost (20% / 40%)

From a capital gain you can deduct either your actual acquisition cost or the statutory deemed cost. The right choice can save hundreds of euros.

The rule in brief

  • Held under 10 years → deemed cost 20% of sale price
  • Held 10 years or more → deemed cost 40% of sale price
  • The tax authority allows the cheaper option: actual cost or deemed cost

PnlTrack picks the cheaper one automatically

For every sale both options are calculated and the lower taxable gain is chosen.

FAQ

How much is the deemed acquisition cost?
20% of the sale price if held under 10 years, and 40% if held 10 years or more.
When is the deemed cost better?
When your actual acquisition cost is lower than the deemed deduction — typically for old positions that have grown a lot in value.
