HI i hope this is a simple question to answer. But exactly how much information do civil partnership / married couples have to disclose on their tax returns about their partners pps number, earnings etc given they have chosen to be separately assessed. thanks ,

PPS number and date of marriage as far as I know. If you're separate assessment, only your income goes in.
