Hi there, @tiffanghu-yahoo-.
If you want to file a Self Assessment tax return in QuickBooks, it isn't possible for now. However, you can use the income and expenses data on the Income Tax page in QuickBooks to help generate an estimate of your income tax.
You can start by:
- Connecting your bank account and import your transactions.
- Categorise and add your business income and expense transactions to your books.
- Based on the categories you've assigned to your transactions, QuickBooks will estimate your Income Tax.
To interact and find more information on Self Assessment tax returns, you can visit HMRC.
