Frequently asked questions

Explore our FAQs for quick answers to your questions

What is a Self Assessment and do I need to complete one?

Self Assessment - often referred to as a ‘tax return’ - is a way for HMRC to calculate how much Income Tax and National Insurance Contributions you’ll need to pay. For contracted employees, your tax is deducted monthly on your employment income through the PAYE system. For the self-employed, or someone with other types of income (e.g. pension or dividends), HMRC needs a Self Assessment to assess the tax required to be paid.

What’s included in the Crunch Self Assessment service?

If you choose Crunch for your next Self Assessment, here’s what you get with the service:

  • Some quick questions on your Self Assessment, giving our accountants more details on you and your finances
  • Once you have completed a spreadsheet of your expenses or money made, this can be uploaded, along with your questionnaire and any other supporting documents, onto our online software.
  • A friendly Crunch accountant who will review your Self Assessment and carry out a thorough quality check
  • A dedicated accountant that’ll contact you to discuss your Self Assessment and if there are anomalies in the information you’ve provided.

Why is Crunch better than an independent accountant?

When is my Self Assessment due?

It can be filed any time from the 6th of April, up until the deadline of the 31st of January. We recommend filing it at your earliest convenience.

How long does it take to get my tax refund after my Self Assessment?

If you’re entitled to a refund, you should allow four weeks for the refund to be sent to your bank account. If you owe any tax within 35 days of your Self Assessment submission, your refund will be deducted from your total owed.
