You probably didn't know that adding your partner to mortgage deeds can result in additional stamp duty charges. This potential pitfall of changing who's on your mortgage is rarely talked about, but it can result in a hefty, unexpected tax bill.
Before you panic, adding a partner to your mortgage does not automatically mean that you'll have to pay more stamp duty. Most case scenarios in which one partner or spouse buys the property and then adds their partner's name to the deeds are straightforward and won't result in any additional charges.
However, there is one common situation when this will be the case that you need to be aware of.
Adding partner to mortgage stamp duty warning
According to Pete Mugleston, MD and Mortgage Expert at Online Mortgage Advisor the first and 'most common' case when you'll need to pay stamp duty after adding your partner onto the mortgage 'is if the person who's joining the mortgage is taking on a bigger share of the property, or all of the share.'
'If the amount they are paying to buy themselves onto the mortgage is higher than the current stamp duty threshold, you must tell HMCR and pay the charge,' he explains.
What this means in practice is that if, for example, you've bought a house for £500,000 and have £400,000 on your mortgage and then decide to transfer half of that to your partner or spouse, their share of the mortgage will be over the threshold – which is £125,000 from 1st April 2021. They will then need to pay stamp duty on the £75,000 that's over that threshold.
Fortunately, this rule does not affect partners or spouses who go half-half at the time of the house purchase.
'Stamp duty isn't usually payable if you're taking on an equal share of the property or have been transferred equity as a gift, but it's always advisable to contact HMRC to double-check the full tax implications of adding someone to your mortgage before you proceed,' Pete explains.
If you do need to declare your new property co-owner, you can find out more on how to do this on the official gov.uk website.
