Gesetzlicher Zuschlag: statutory surcharge (10%) in German health insurance

What is the Gesetzlicher Zuschlag?

The Gesetzlicher Zuschlag (statutory surcharge) is an additional 10% on top of your PKV premium that German law requires insurers to charge from the calendar year after you turn 21 until the end of the calendar year in which you turn 60. The legal basis is § 149 VAG (Versicherungsaufsichtsgesetz). Every cent of the surcharge flows into the member's ageing provision (Altersrückstellung), it is not a profit margin for the insurer.

The mechanic is pre-funding. Healthcare costs rise with age. Rather than letting premiums drift upwards year by year, the law forces a surcharge during the earning years when members use healthcare little. That surcharge builds a reserve that later cushions the cost curve.

Who pays it?

• Every member in full private cover (Krankheitskostenvollversicherung) during those years

• Not paid on supplementary policies (Krankenzusatzversicherung): those have their own reserve rules

• Not paid in temporary contracts, in tariffs that end by the statutory retirement age at the latest, or in the Notlagentarif (emergency tariff for members in arrears)

The surcharge is calculated on the base premium only, not on optional add-ons like premium-relief tariffs (BET).

When does it end?

On 1 January of the year after you turn 60, the surcharge falls away automatically. The cut-off is calendar-year-based (someone who turns 60 in March pays the surcharge until 31 December of that year). You do not need to apply; the insurer stops charging it on the next invoice.

An important detail: the end point is tied to the calendar year in which you turn 60, not to your retirement date. If you retire at 63, the surcharge has already been gone for more than two years. If you keep working, it stays gone.

For a base premium of €550 per month, the surcharge contribution during working life is €55. When it ends, the next invoice drops by €55.

How does it interact with other costs?

• Employer subsidy: applies to the full premium including the surcharge. The employer pays half of €605 (base + surcharge), not half of €550.

• Tax deductibility: the surcharge is part of the premium your insurer reports for tax. The share of that premium for basic cover is deductible in full under § 10 Abs. 1 Nr. 3 EStG, without the cap that applies to other insurance.

• Tariff change (§ 204 VVG): when you switch tariffs inside your insurer, your accumulated surcharge capital moves with you. The reserve stays yours.

• Insurer change: only the Basistarif-equivalent portion of the reserve transfers. The rest stays with the original insurer.

The common misreading

"I pay 10% more and get nothing back for it" is wrong. The 10% is not lost, it funds the reserve that stabilises your premium later. § 150 VAG (from age 65) deploys it to dampen future increases rather than actively cut the monthly figure, and the broader Altersrückstellung pool keeps the baseline premium lower in old age than it would otherwise be. Compared to a system without the surcharge, the working-life premium is higher but the retirement-phase premium is materially lower.

It is also one of the reasons PKV premium comparisons done at a single point in time are misleading. A 35-year-old quoted at €605 is paying €550 base + €55 surcharge. Another insurer at €575 may have a different base-and-reserve structure. You need to compare lifetime cost, not just the headline at 35.
