DH is self employed. He had a really bad year 22-23 which we've just now found out he'll have a tax refund of about £4000. He's currently having a very good year and has turned over £27,000 so far this tax year but he's only actually saved £1500 for his tax bill. He's supposed to save 20% of every payment that comes in which more than covers his tax bill once his deductions and personal allowance are taken into account which he does but he's aways behind so he saves out of the current year for the previous year which never works out properly. He had such a large tax bill last year (that's now being refunded) that he had to pay savings from this year to pay that in July which is why it's so low now even though generally he is pretty consistent at putting aside his 20%.
He also built up £7000 worth of debt during the bad year last year which he has on a 0% credit card but in a year he's only manager to get it down to £4700. The 0% interest period runs for 6 more months.
The tax refund plus his tax savings will clear the credit card and free up the £100 minimum payment he's committed to every month and free the burden of having to pay interest once the 0% runs out. But of course then he has to save for his tax bill for January 2025 from nothing.
Either way, I will be helping him out. I'm PAYE but earn a lot more than him and am better at saving so one way or another both will get paid. I've just returned from maternity leave so my savings have been pretty scarce recently but they're building up again now and I can save about £500 a month comfortably I will definitely be able to help with either if I have to.
I'm just not sure which would be a better use for this money. It would bring him up to where he's supposed to be had he not used so much to pay the July tax bill for last year. But then is it better to just get rid of that debt so it's no longer hanging over him and then work on saving up for the tax bill over the next year?
Thanks in advance.
