On behalf of my husband -

He's started a new job with a Swiss contract employed by a UK company and is under the ANOBAG scheme. His company are in the process of setting up a Swiss office but no timeline as yet. Under ANOBAG I understand that it is my husbands responsibility to pay both employee and employer social security contributions and he has just received a bill from OCAS instructing him to do so. First query -

- He has just received his first play slip from the new employer and one half of the contributions (presumably employee) have been deducted. So why has he received a bill requesting it to be paid again along with the employer contributions
- His company agreed to pay their share of contributions (even though they are not obligated to) - they agreed to it formally in his contract - is this a thing? Can they pay their half if they want to and how would they do that? What is the process - somewhat disconcertingly they don't seem to be clued up on this.

Advice appreciated.
