I understand how important it is to use the correct tax year date for your Partnership Tax Return, Thelines. However, QuickBooks only supports VAT returns and Payroll taxes.
To ensure your first Partnership Tax Return is completed accurately and complies with HMRC's regulations, I recommend contacting HMRC directly. They can provide reliable guidance on the appropriate submission dates and help you avoid potential issues.
If you have any additional questions, feel free to return to this post anytime.
