Yes, that is the difference: Riester capital is tax-advantaged during the accumulation phase, there are either allowances or tax reductions. (FA checks which is more favorable). However, Riester capital is considered as income when paid out.
Let’s compare that to a fund savings plan. Nothing is favored when paying in; if dividends and distributions exceed the saver’s allowance, taxes are already due. However, in the payout phase, the money flows to you tax-free.
What still makes Riester attractive? The allowances are high—the payable income tax in retirement is often low. For example, someone receiving a 3000 pension per month, which would already be a high pension, has an annual income of 36,000. Now add 1000 per year from Riester, making it 37,000. That is almost tax-free. Approx. 18,000 basic allowance leaves 19,000 to be taxed. Deducting some advertising costs etc., peanuts remain for FA. K.
