Can I work remotely in Thailand while paying UK taxes without facing double taxation issues?

I have been told by my employer that I am OK to work remotely in Thailand on a pert time basis 25 hours per week.

This suits me fine as I was going to retire/semi-retire.

Is anyone else doing this from the UK as I would like to know about the double tax arrangements and whether this forms any part of the DTV application.

TLDR : Answer Summary
The user inquires about working remotely in Thailand while being employed by a UK company and seeks clarification on double taxation implications and the relationship with the DTV application. Comments highlight that tax issues are separate from the DTV application, stating that tax liability arises only if one becomes a tax resident in Thailand by staying 180 days or more. As the user will pay UK taxes, they are unlikely to face double taxation due to the UK-Thailand Double Tax Agreement, with advice to consult a tax specialist.

As long as you pay your correct income taxes in the UK you have no tax liability in Thailand at this point in time, even after 180 days in the year.

that is not true

Tax has nothing to do with the DTV and no part of any application.

maybe I didn’t write this correctly. My DTV will be processed based on a letter from my employer stating that I can work remotely.

My tax will be deducted from my salary exactly as it is now.

But I don’t want to be taxed twice otherwise I will not work and retire completely.

So you salary will be taxed in UK? If so if it is then remitted to Thailand it will be subjects to the Thai-UK Double Taxation Agreement. You will nkt be taxed twice. In some cases there can be a slight differential in rates but then you are really getting into the reeds. I would not be worrying about it to be honest. In fact Thailand already talking about rescinding the overseas earning rule brought in for 2014

hence Im hoping to chat with someone also doing the same thing…

It might be that I have to pay the tax in thailand and then claim it back from the UK at a later date. I know there is a question on my tax form that I submit each year which asks, how many weeks per year did I work outside of the UK.

@John ********
Yeah. Check with a tax advisor. When I worked outside UK I signed out with HMRC that I was no longer tax resident. Pal working offshore fell foul one year as spent too many nights in UK and ended up owing. I do not think you will have any issue at all with Thailand unless company is paying you direct into account here with no tax withheld anywhere.

no all my payments will be to my uk bank account exactly as now.

I wont be returning to to UK. Just a couple of trips to Greece in september and italy in May.

@John ********
So you are paying UK tax at source. If you do not tell HMRC you are NOT tax resident then will anything change? As for Thailand unless you remit vast amounts into a Thai account I doubt they will notice. There is a Thai-UK DTA. Have a read. It is quite short. You will not be double taxed.

i have to state on my self assessment tax form each year: ‘How many days were spent working outside of the uk’

There's no tax implications as far as the DTV is concerned. Tax implications only become relevant if you become a Thai tax resident (180 days or more inside Thailand in a calendar year). Any income you then bring into Thailand is potentially liable to thai tax, and if you have already paid tax on that income in a country with a Dual Tax Agreement with Thailand you can claim a credit for tax already paid on the income

Perfect thanks John

@John ********
pro rata to the relative income you bring in to Thailand. All in the DTA between UK and Thailand

@John *********
i will check the DTA.

Its not a necessity I work. Just considering whether its worth it.

@John *********
what is pro rata in this instance John?

If im 100% out of uk…
John **********
@John ********
pro rata just means if you have income in the UK and you bring 100% if that income into Thailand you can claim 100% taxy credit but if you only bring 50% of that income into Thailand you can only claim 50%

when you say bring in to thailand, my money is aid into my uk bank. And as I cant open a thai bank account on a DTV, there is no other option
John **********
@John ********
it doesn't matter how you bring it in. If you withdraw from your UK account using an ATM in Thailand that's bringing it in. If you transfer to a friend's account in Thailand that's bringing it in. Whether you have a bank account in Thailand or not is immaterial

ok so I pay tax on my money in UK, but as I draw it out from an ATM, i claim credit against it from the tax ive already paid on it in the UK?

@John ********
not quite. It's a once a year thing. The Thai tax year is the same as a calendar year, and you file your thai tax return between 1st January and 31st March for the year just gone. So you work out your thai tax liability for that year, then you work out the allowances and credits you can claim for that year. Then you pay Thai tax (if any) according to the requirements

Taxes and DTV are separate matters. You automatically become a fiscal resident when you spend 180 days or more in Thailand within a calendar year. You could be taxed on money remitted to Thailand (via transfers, cash, or cards), and the amount depends on various factors, including tax treaties with your home country. I would advise settling here first, then consulting a qualified Thai tax specialist.
