If you have assets or money held overseas, you may still have a tax liability to pay in the UK. Due to global tax transparency laws, tax authorities around the world are able to share information.
We can help you understand your position.
Online Trading via eBay etc
If you generate income from online sales via platforms such as eBay, Etsy, Vinted, Depop, AirBnb, Only Fans, Patreon, Spotify etc, you may have unpaid tax liabilities.
Talk to our team if you have been trading items, selling online and generating income.
Crypto Currency / Forex Trading
HMRC is now more actively looking into crypto currency to ensure that investors are aware of their tax liabilities through such investments.
Put simply, crypto currency is subject to Capital Gains Tax in the UK if profit has been made on the investment.

Making a Voluntary Tax Disclosure is a good way of showing your willingness to bring your tax affairs up to date. There are a number of options available if you have unpaid tax.
Our team will discuss your circumstances and assist you through the process with HMRC.
