Hi, my neighbours got a cleaning lady, so this is what she told me: The first time you order a cheque book at your bank, you'll need to fill out a special form (at the bank) to declare you as an employer ,includes directdebit authorisation, so the employer and employee charges 'cotisations' can be debited from your account. So yes you're pretty much right, you'll have to count apprx an extra 50% for the charges For french income tax payers, they can declare the pay + cotisations, to make a tax reduction; however in your case being non-resident I think it's tough luck!
