Hi Khalid, the tax error occurs when your filing details, particularly the filing schedule, differ from the HMRC records. Let me provide an example to rectify this.
In your case, I suggest checking your filing schedule in QuickBooks and verifying if it matches your schedule in your gateway account. Also, if you're accessing QuickBooks from outside your country, the time zone might be different.
For example, you could be 1 day ahead of the UK time zone. So, when you submit the return, the end date might fall before the current date. In this scenario, you may need to wait for the current date in both your country and the UK to align, or you can use a VPN to synchronize with the UK time zone to fix this.
