If you have a difference between your VAT Return and your VAT nominal account, there are a number of things you can do to reconcile this and find the difference you are seeing:
Check for any transactions in the VAT control account that are of the type JNL (journal) as these are not included on the VAT Return
Check for any transactions that have a VAT code of 0 but have a VAT value. If this is the case, the VAT isn't included on the return.
Use the detailed VAT Return report and compare this to the individual transactions.
Remember that up until the point where you update the VAT Return, the figures aren't updated. You may want to run a return for a single period and compare this to the same transaction period on your nominal account.
Remember that if you use multiple VAT accounts you must take all of them into account when comparing your figures.
Comparing the transactions included on the return against the transactions showing in your nominal account allows you to locate any issues coming from transactions. If this is the case, you can correct these either by reversing and re-entering the relevant transactions, or by using corrections module.
If you still find a difference once you've compared your return figures with your nominal, please raise a new case online and reference the title of this article. When raising the case, please include all the relevant information you found when doing the above checks.
