Frequently Asked Questions
Self-employed individuals, those with property income, and people earning from sources not covered by PAYE must complete a self-assessment tax return. Additionally, individuals with complex financial affairs may also be required to file.
The deadline for submitting a self-assessment tax return in the UK is typically 31st January, after the end of the tax year. However, it is recommended to submit well before the deadline to avoid last-minute issues.
Missing the deadline triggers an automatic £100 penalty — even if you owe no tax. After 3 months, £10 daily penalties apply (up to £900). At 6 months and 12 months, further 5% charges are added on top. Contact us as soon as possible and we’ll help you resolve it quickly.
While it is possible to complete your self-assessment tax return yourself, the process can be complex and time-consuming, especially if you have multiple income sources or complex financial affairs. Engaging the services of a tax accountant can help ensure accuracy and compliance while saving you time and reducing your stress.
