UK sole trader QB online account. I have employed income as well as my self-employed income. Can I add my employed income so QB will correctly calculate tax and NI?

Glad to have you here, Simon.

Currently, QuickBooks Online for Sole Traders (UK) is designed to calculate tax and NICs for your self-employed income only. Your employed income has already been taxed by your employer through PAYE system.

It's also worth noting that you don’t need QuickBooks to combine these calculations. HMRC will calculate your overall tax and NIC liability based on your total income (employed + self-employed) when you file your Self Assessment tax return.

Moving forward, for a full calculation that includes your PAYE salary and NICs. You can consult your AC to help ensure PAYE income and any reliefs or allowances are handled correctly.

Here's a link for additi0nal information about income tax: Understanding Income Tax in QuickBooks.
