Those who split there income - how do you go about pensions, investments etc? What if one of you is on a low wage - does that mean you can't live the dream life because one of you is poor???
What if one is you is more knowledgeable with money...what if the wife doesn't pay into a pension or has lower contributions? Does that mean in retirement she'll live on rich teas whilst you have the jaffa?
I earn twice what my wife does, but we're fortunate enough to both be on good incomes.
We set everything up to be as equal as possible net of all of our costs and savings. So both net incomes go into a joint account, the bills, savings and standing orders etc come out and then we split the remainder equally into our own individual accounts.
For us, pensions took a bit more thought, as there's tax relief to consider as well as tax due when drawing on the pensions, plus I'm 9 years older than my wife. So we worked out (I used to be a financial adviser and still work in pensions) what would overall be the most tax efficient way to bring our two retirement ages as close together as possible. Our own solution was to increase her pension contributions to the point where she no longer pays higher rate income tax, maintain mine at a relatively high level, and have individual savings plans (ISAs) to build up capital. It is actually pretty easy for husband and wife, as the tax wrapper advantages of both pensions and ISAs pass to the spouse on death.
In very simple terms, we modelled cashflow from the moment I hope to retire, through to when she retires through to when the last of us expects to draw the State Pension, and worked out the most tax efficient way of doing it (drawing from pensions, drawing down from ISAs). Then we worked our way back from there to work out how much we need to save, into what and into whose name. It is complex but at the same time it isn't really difficult. The first retiree draws on pension income / tax free cash until the second retiree retires and does the same. Then, when the State Pensions kick in you start to draw down more from ISAs instead of the pensions in order to minimise income tax liability. There are a few other considerations too but that's the basic stuff.
I don't think either of us is living the dream, but we're both equally comfortable with what we have and we'd like it to remain that way into retirement.
