Hi Hurstcroftuk, the issue you're encountering is due to a current limitation within the Pro Tax Company Tax (CT) integration. Since the system does not yet support tax returns with start dates after March 31, 2025, the Year start field is in red, and the workpapers are not available.
For further assistance or potential workarounds, I recommend reaching out to our QuickBooks Online Accountant live support team, as they can provide more direct technical guidance about Pro Tax concerns.
To get the best time to call, please check our support hours.
If you have more questions, please don't hesitate to reply here.
