+**What is it?** YEL _(sv: FöPL)_ is a mandatory social security insurance for `self-employed` persons.
 **YEL official name is very misleading** (*Self-Employed Person’s Pensions Act*), because **YEL determines your entire social security benefits**, <ins>not</ins> just your pension.
 
 For example, if you get sick, your *daily sickness allowance* is calculated based on your YEL. The more you pay for YEL, the more *daily sickness allowance* you get.

+**What is it?** On top of [YEL](#buy-social-security-insurance-yel), which is mandatory, you can buy *voluntary pension insurance*.
+Payouts can start at the age of ~70 and have to be paid out during at least <ins>10 years of time</ins>. Depending on the provider, you can typically choose what to do with the money in the insurance (invest in stocks/bonds/etc).
+
+**How much?** Depends on the coverage you choose. The higher the coverage, the more you pay in premiums. Premiums are a business expense and fully tax-deductible up to 8,500€/year. Above this limit, premiums will be taxed as personal income for you, the `self-employed`.
+
+**How does it differ from YEL?** If you die before reaching the pension age, what you've accumulated and paid for YEL goes to /dev/null and disappears. With voluntary pension insurance, you can include a life insurance, so that your spouse or some other beneficiary can inherit the full value of the voluntary pension insurance you have accumulated and paid for.
