Hi,
I'm moving back to Scotland after 17 years in the Netherlands. I'm selling a house here... With my ex husband. I'm massively confused by the rules on the tax year.

Our house is sold under conditions so the actual sale will complete in November. If I move back and become resident in UK before that, will I be paying tax on that? I was thinking of being back in October so it's about 3 weeks before the sale.

On moving I would stay with my mum until i buy a house. I've started with her a few times this year... I have no idea if those visits accumulate as time in the country or not.

I'm also working on a TOR form to ship my things over. I'm assuming I can ship those in September without any issues...

I've seen people mention an HMRC calculator to work out this stuff. Does anyone have a link that could help me?

Thank you!

Do you mean capital gains tax? If so, you can calculate that here - https://www.gov.uk/tax-sell-property/work-out-your-gain

It's not clear what kind of calculator you're asking about. If you mean trying to figure out when you become tax resident in the UK (since you mention you often visit the UK) you might find this helpful:

Visits to the UK do count towards the tax residency requirement.

I know nothing about the tax treaty / relationship between UK and Netherlands, but my general thought would be to try to ensure the property sale goes through while tax resident of the Netherlands if possible, simply so you only have to deal with one taxing authority instead of two.....

Are you planning on moving to UK before or after the sale of the property?

Under normal circumstances you will pay some tax on (your half) of the home to be sold, but you should go to a tax advisor or accountant as NL tax rules are complex and have changed considerably regarding property sales. This is especially important where couples have split up as those rules are different but also quite strict. Different terms may apply to your ex-husband if he is remaining in NL.
