How are business savings accounts taxed in the UK?

In the UK, interest earned on business savings accounts is taxed based on the business type. Each business entity type faces different tax obligations:

1. Sole Traders and Partnerships: For a sole trader and partnership, the interest that is earned from business savings accounts is considered income tax. This must be declared on a person's Self-Assessment return and taxed appropriately in line with total income. This type of income is total income and would therefore be assessed against the relevant income tax band applying to their level of income.
2. Limited Companies: In the case of limited companies, interest earned from business savings is treated as business income. This means it is subject to Corporation Tax. The rate of Corporation Tax is applied to all profits, including interest income, and must be reported in the company’s annual financial statements.
3. Personal Savings Allowance: An allowance for individuals who have derived interest from their savings, where such interest is exempt from tax up to specific limits. This depends on the limit of income tax rate applicable to the individual. Basic-rate taxpayers enjoy a higher allowance, while higher-rate taxpayers enjoy a reduced allowance. Additional rate taxpayers enjoy nil allowance; thus, their interest is fully liable at applicable rates.
4. Tax reporting and compliance: The business or person is required to keep proper records of interest earned and report it correctly on their tax return. Failure to report income correctly may be subject to penalty assessment or rejections.

Businesses are strongly advised to consult a tax professional to be on the right side of the law in paying taxes or claiming available tax allowances and deductions that will ensure an optimized tax position in good financial management.
