How open are you with your partner about your finances?

Child benefit changes mean that, from next January, high earners may be expected to declare their earnings to their partners. You'll be able to find out from HM Revenue & Customs if you partner earns more than £50,000 per annum or is receiving child benefit. Some argue that such a move breaches the confidentiality principle that has been fundamental to the tax system for more than 200 years. But little has been said of the potential impact this may have on spending behaviour, or indeed, the relationships themselves. Are you honest with your partner about your finances, or are you sneakily building up a little nest egg without their knowledge? Do you feel guilty about hiding extravagant purchases from your partner, or do you feel your personal bank account is an important bastion of privacy?
