- Common Questions
Frequently asked questions about UK tax returns
When is my self assessment tax return due?
When is corporation tax due?
The CT600 return is due 12 months after the end of the accounting period, but the tax itself is due 9 months and 1 day after the period end. So the tax gets paid before the return is filed.
Do I need to file a self assessment?
Yes if you’re self-employed earning over £1,000, a company director with untaxed income, a landlord, earning over £100,000, claiming child benefit on income over £60,000, or have foreign or investment income above the allowance. We can confirm in a 10-minute call.
What if I'm late filing?
HMRC charges an automatic £100 penalty for missing the 31 January deadline, with further penalties stacking up at 3, 6, and 12 months late. We can still help you file, but the sooner the better.
Do I need to send in receipts?
No, HMRC doesn’t want receipts with the return. But you do need to keep them for at least 5 years (sole trader) or 6 years (company) in case of enquiry. We’ll help you set up a system if you don’t have one.
