I can help with this one.
To mark a period as filed in QuickBooks Online without submitting said return to HMRC, you would simply need to follow the below steps.
This will file the return within QuickBooks only, closing off that period for VAT, and not duplicate your submission made directly to HMRC. If you wished to use the Online Submission feature for your future returns, you can follow the steps in our article - VAT Online Submission direct to HMRC – for guidance.
Let me know if you have any queries. Or, if you'd like to go through this over the phone, you can call our dedicated team who will be happy to assist you. Our contact details can be found here along with our opening hours.
I am also trying to 'mark as filed' as I have submitted the return to HMRC separately.
However after I select mark as filed I have an error message which says 'you must click save again to make this change prior to the closing date',
I can't see a save options I can't get past the message. Can you help?
Hi there, Jenny1979.
Thanks for joining this thread. Allow me chime in and help move past the error.
You’ll have to turn off the Close the books feature, so QuickBooks will allow you to mark the tax return as filed. I’ve laid out the steps to accomplish this task.
After completing this process, go back to the open return and submit it. These steps should help mark the VAT form as filed.
Please update me on how things go. I want to make sure everything is taken care of and you're all set with this concern.
