A parliamentary committee is discussing how the 13th pension payment should be financed.
In March, voters agreed to pay all those on a state pension an extra month’s salary – but it has to be paid for.
The Federal Council favours a rise in VAT, but many believe it won’t be enough.
Other ideas include increasing employee contributions - it would need a rise of nearly 1% - that gets support from the left as it will be a progressive tax.
There has also been talk of a new tax. Such as a fee on financial market transactions or a federal inheritance tax.
Another idea raised was whether those who receive a pension but live abroad, should be covered?
But there’s also no immediate rush. It will be at least two or three years before the payment needs to be made.
