What it does

Cat. E investment income (dividends, interest) and Cat. G short-term securities gains are taxed at a flat 28% by default — no aggregation required. For higher earners this is materially better than the 44.6% / 48% top brackets.

Watch-outs

If your total taxable income exceeds €86,634, securities gains in Cat. G are subject to mandatory aggregation (englobamento) and lose the flat-rate benefit.
