The value of transactions carried out with your clients and VAT due on them
The value of transactions carried out with the suppliers/service providers (incoming transactions) and the deductible VAT
The return shows you the difference between the VAT due and the deductible VAT. If it is in favour of VAT due, then you will be owing the state the particular amount. If it comes in the favour of deductible VAT, then state will be owing you. To explore further into this subject, please refer to this source.
How do the app calculates your VAT return?
There is a specific code for each category fixed by the tax administration. What the app does is, it computes the specific invoice or ticket and then adds it to a particular category defined by code number. For example:

This is the screenshot of the auto generated VAT return by the app. You can clearly see the categories on the left hand side, the relevant code in the middle and the accumulated values on the right hand side. Once, you will click on the specific row, the breakdown of the accumulation will appear as you can see underneath:

After the generation, you can easily export this document from the application and then file your VAT return on the Intervat platform after importing this document over there.
Note: When you will file your VAT return on Intervat, the codes will be match with what you can see on Intervat.

The coaching session on tax management was excellent, good material, excellent explanations and very insightful…my accountant and tax advisor are good, but never so comprehensive and accurate. Combined with the AI I never feel alone with Accountable

The availability of your team to help and guide people to understand their finances better is what really makes Accountable valuable. While the AI is able to give answer to most of the basic questions, specific scenarios need counsel from a human which your team performs beautifully.
