How much cash I can show in my individuals balance sheet

When filing your income tax return for the first time, you might wonder about declaring significant personal savings. While there's no strict limit on cash shown, it's generally only applicable if you're running a business. For personal savings, it's often best to declare it as income in the current year, especially if you're under 18, as there's a tax rebate for income up to £500,000. Proving the source of large cash savings to the tax department can be challenging, so declaring it as income is usually the most straightforward approach.
