I have recently placed my wife's name on the deeds of my rental property as 50/50 ownership and she is now no longer working due to the birth of our 2nd child. I have in previous years completed the self assessment tax return on behalf of myself as I was the sole owner. I would just like to understand how I can use my wife's income tax allowance to reduce the tax I pay on my rental income now she is a joint owner. Can I use my wife's full allowance to offset? Would both myself and my wife therefore be required to complete seperate self assessments at the end of each tax year?
Thank you for your question. Your wife will have to register for Self-Assessment and complete a Self-Assessment tax return if her share of the gross rental income exceeds £10000 or her share of the net rental income exceeds £2500. Please see further guidance at
If this is her only income she would be able to offset her Personal Allowance against this. When you complete your Self-Assessment tax return you should only declare your share of the rental income. You cannot allocate any of your wife's unused Personal Allowance against your share of the rental income. I hope this helps.
Can I please just clarify further around my wife filing when you state " if her share of the gross rental income exceeds £10000 or her share of the net rental income exceeds £2500."?
GROSS rental income £1000 per month (£12k per annum). My wife's Tax free allowance £12,500.
Given my wife is not in employment, can the rental income simply not be taken into her personal allowance? or do I have to apply a 50/50 split so 6k assigned to me and 6k assigned to my wife? Its not clear what I am able to apportion to each of us?
If you now own the property in equal shares 50/50 you should each declare half of the income and half of the expenses, ie £6,000 as in your example.
Your wife's share will be covered by her personal allowances if she has no other taxable income.
Your share will be added to your other income and taxed at the appropriate rate.
The figures quoted of £10,000 and £2,500 relate to the criteria for self assessment. Your wife can transfer 10% of her personal allowances to you, if you meet the criteria.
Please note if you are liable to tax at a higher rate (40% or 45%) the transfer cannot take place.
This link explains how Marriage allowance transfer works:
I also share rental properties with my wife. My wife does most of the work relating to the rentals, (checking the properties, cleaning, arranging maintenance etc.) can we split the income in unequal shares based on the share of the work although we own the property 50/50?
If you live with your spouse or civil partner and jointly own property, then you would normally each be taxed on 50% of any income arising from renting out the property. However, married couples and civil partners can, in certain circumstances, ask to be taxed on their actual entitlement to income from jointly held property based on actual share of ownership. They can do this by making a joint declaration of unequal beneficial interests on a form 17 and submitting this to HMRC together with evidence of the actual split of beneficial interests.

Declaration of Beneficial Intererst
Income would as you say be split 50/50 between a married couple or civil partnership with each of the partners needing to declare their share of income to HMRC. Although you cannot use your wife's unused allowances, there are occasions when a spouse or civil partner can opt to transfer 10% of his/her unused Personal Allowance to the other partner. This is the Marriage Allowance. Further information can be found on our website under the following link;
