Hi All,
I am not very clear on How Rent a room scheme Tax is calculated if you have a partner/married who shares your house.  I wondered if you could help me please :

If you have a shared property ownership with your partner and you rent a room, how is the tax for rent a room calculated for the year ?

Assuming that Rent income is £10000 for the year 2015-2016
Tax free threshold is  £4250
For each partner Tax free threshold is £2125
For each partner Rent Income is £5000 (half of the total income for the household)

One partner doesn't earn high enough to pay any tax.
The other partner pays 40% tax on Salary.

Then is it correct to say that high earning partner will pay 40% tax on £5000 income - £2125 = £2875 @ 40% = £1150

I would be grateful if anybody can share any light on this ? Thank you in advance for your time.

My understanding for rent is that it should be allocated to each party at the same proportion as their beneficial interest in the property so if it is 50/50 then there would be no chance of allowing your partner to take all the rent as his/her income. I am not an accountant but that's what mine told me.Makes sense I suppose.
