What investment advice can you get in the UK for managing a lump sum and understanding tax implications?

As a Thai tax resident any UK dividend income is paid out tax free. Find yourself a decent brokerage, I use low fee Degiro, and pick funds or shares based on your risk tolerance that have historically paid decent dividends. Aim to generate stable passive dividend income to supplement your pension. Avoid anything that has a platform or fund management fees.

Whisky is my investment choice

A really simple one is use the MSCI world index fund inside the Wise account. You could do a lot worse although there will likely be a correction soon. Your age and investment horizon matter. If you're UK resident you should be doing tax returns and reporting any capital gains and dividends. In Thailand dividends are treated as regular income. Go see an accountant

Buy gold

Yeah. Hire a financial advisor and not refer to random people on a visa group. But gold is always a good start

I allocate 90% of my portfolio to the global stock market and 10% to gold. However, no one should invest without first having an emergency fund. Investing is a long term strategy ideally 5 to 10 years or more, because both of these assets can be volatile. Believe it or not gold has actually been more volatile than the global stock market the past 30 years

There are many investment opportunities out there but like most things it depends what you are looking for and how much you are wanting to invest? Are you looking at a regular income ? What risk level are you happy with? Premium bonds are ok if you are looking at paying higher tax rate if not then a high interest savings rate is better? Be aware many investments in the uk including premium bonds needs you to have a uk address and/or say you live in the uk. Also same with uk bank accounts these days they can close your account if you dont live in the uk. I would suggest if you have family in the uk you register at their address and use that for your accounts. Also the thai tax authorities are looking at updating their tax laws in January 26 but will have to wait and see if it happens this if it does will make bringing money into thailand much more simple and probably little chance you will ever pay thai tax

I had premium bonds ages ago for about 3 years, never won 1 prize over £25. I won 4 prizes of £25 in one month but that was it. I won on average £25 every 3 or 4 months. IMO really not worth it

Gold is the best investment for guarantees. Crypto is a big risk but worth a punt as if you went to a casino with a set amount you are prepared to lose.

4 years ago gold was around $1800 if I remember correctly and its now over $4000 but its a long term investment. If you're looking for a quicker return, I doubt there is anything apart from chosing the right crypto or investing in S&S

*Im not any where close to being an expert so there could be options out there I am not aware of and Id expect plenty of other advice incoming 👍
