vAT declaration

Oh no, no, don't do that!

Once the vAT declaration has been submitted, it has been submitted! You can no longer make any changes or add anything. If you still have purchases, just enter them with the normal invoice date and then change the fiscal date. For example, you have an invoice dated 01/06/2022 and that vAT declaration has already been submitted.Then you enter the purchase date as 01/06/2022, but you set the fiscal date to July/2022 (i.e. quarter 3). There is also a video about this if you click on the fiscal date in that entry in Dexxter, where they provide a detailed explanation. So, quarter 2 has been submitted, it's done. Don't change it, unless you've made really serious mistakes and need to correct them. But you shouldn't enter an old expense. You should just enter it in the next quarter using the fiscal date.There is something from it in the learning center, I can't get it back right now, but it was/states to be somewhere. Something about 'old invoice' or something like that.

Just found it via the blog on the Dexxter website:

There states your answer! ;) So, as 'PE' says: just include it in your next vAT declaration.
