Try asking about the tax situation at r/ukpersonalfinance

I quick search suggests that you need make a US tax return while you are a US citizen but that doesn't mean you will pay any US taxes on top of the UK taxes.

As u/parkleswife points out there are rules like FATCA

> Many Americans living abroad qualify for special tax benefits, such as the foreign earned income exclusion and foreign tax credit, but they can only get them by filing a U.S. return. For further details, see Publication 54, Tax Guide for U.S. Citizens and Resident Aliens Abroad.

I have dual citizenship with the UK and USA and as far as I know since 2003 you have not had to pay double income tax, that is tax on your normal job income. If you have other sources of taxation like investments then things get tricky. Either way you will definitely want to make sure you talk to someone qualified about it as you do not want to be in a situation where the IRS gets its hooks into you for non filing or something like that. If you do not have dual citizenship already your big problem will be getting a working visa depending on what your qualifications are and what sort of work you are looking to do.

Overall I think the UK is a bit of a friendlier place for dealing with sight stuff than the USA. I have lots of buddies in California and I love spending time there, but the old saying is that Uncle Sam doesn't give a damn and people are much more likely to step over someone who's lying twitching on the sidewalk there than here.

Don't give up your US citizenship! It's not really possible ever to get it back, or at least without crazy amounts of work.

If you get to London look me up!

That would be very strange. Usually, countries always try to avoid double taxation. Taxing it's citizens twice is not good economics. Ideally, the person should be taxed in the country where he earnt the income. Some countries might also work out a tax sharing agreement of sorts, where the collected tax gets split in to 2 countries. But, double taxation is very bad thing, highly doubt countries like US or UK would be doing this to their citizens.

If you try to send the money though, like remitance, that will be taxed most probably.

Get an accountant who knows the law and regulations thoroughly.

Reading as much as one wants on the law, on accounting practices, etc., is a fine start, but eventually becomes limiting.

(As an aside, a conversation with a lawyer specializing in Constitutional law can be very surprising, and illuminating, and sometimes downright funny. When someone spends decades doing highly technical work, and doing that work well, they tend to know things the layperson may never hear about.)

If you’re worried about paying thousands or tens of thousands of dollars in taxes, then the rate of a good accountant is a very easy expense to justify. You may have already spent the equivalent of a few hundred dollars of your time on this matter.

Smiley face emoticon would go here, if I used those.

Best of luck! You found something you want, and a professional can take care of the details so you can focus on what’s fun for you.

I'm just an 18-year-old living on the other side of the world and have no idea about taxes, what taxes do you have to pay as a US citizen when you don't even live in the country?

Why would you ever even consider renouncing your US citizenship? Don’t do that. Best of luck with the move.
