Frequently asked questions

Go to support page
What does ISA stand for and how does it work?

An ISA (Individual Savings Account) is a tax-efficient account that allows you to save or invest money each tax year without paying tax on the interest on cash, income or capital gains you earn.

There are 4 types of adult ISA accounts available:

- Stocks and Shares ISA
- Cash ISA
- Innovative Finance ISA
- Lifetime ISA

A stocks and shares ISA lets you invest in “qualifying instruments” such as stocks and shares, funds, bonds,  etc. It is not an investment in its own right, but rather a tax efficient ‘wrapper’ which protects your eligible investments from Income Tax and Capital Gains Tax.

With a MEXEM UK stocks and Shares ISA, you have access to the global market, and are able to choose from a range of investments to invest in.

When choosing the right ISA for your needs, it's important to consider your financial goals, risk appetite, and personal circumstances. MEXEM UK offers Stocks and Shares ISA only.  

Please note, tax treatments depend on your individual circumstances and may change in the future. This information is based on HMRC guidance.

How much can I contribute to an ISA each tax year? / what is the ISA allowance?

The ISA allowance is the maximum amount you are allowed to contribute across all your ISAs during a single tax year. The UK tax year runs from 6 April to 5 April of the following year.

For the 2025/26 tax year, the ISA allowance is £20,000 per person. You can divide this allowance across different types of ISAs, as long as you subscribe to only one of each type within the same tax year.

Any unused allowance does not carry over to the next tax year.

Important Information:

If you already subscribed to a Stocks and Shares ISA with another provider during the current tax year, you cannot also subscribe to a MEXEM UK Stocks and Shares ISA in that same year.

To view how much you have contributed to your MEXEM UK Stocks and Shares ISA and the remaining allowance available you can check this in your Client portal Transfer & Pay > Deposit page . Note, this assumes you havent subscribed to any ISAs elsewhere.

For more information, visit the HMRC ISA allowance guidance

What is a flexible Stocks and Shares ISA and how does it work?

In a flexible Stocks and Shares ISA, any amount you withdraw can be paid back in within the same tax year without reducing your annual ISA allowance.

Can I transfer my existing investments or cash to MEXEM?

Yes. You can easily transfer both cash and existing investment positions from another broker to MEXEM UK.

Stock & ETF transfers: Most UK and international listed securities can be transferred in-kind.

Cash transfers: Supported in GBP, EUR, and other major currencies, credited directly to your MEXEM UK account.

ISA transfers: We accept Stocks & Shares ISA transfers from other ISA managers, with no exit or entry fees from our side.

Can I upgrade from a GIA Retail classfication to a Professional classication?

Yes. Eligible clients can apply to be classified as an Elective or Per Se Professional Client under FCA COBS 3.5.

This provides access to greater leverage, subject to FCA suitability criteria.
