To all experts, since I am no longer looking through, I turn to you with the hope of assistance. Due to an accident there is an expert report that has been prepared. Now there is the possibility of fictitious billing. The VAT will not be paid out at first. If in retrospect a/several partial repair/en is carried out, the VAT can (in my knowledge) be applied retrospectively. 1. How long do I have time for this? Is it sometimes also possible to submit an invoice after 6 months (after the day of the accident), e.g. if a summer tyre (which appears in the report) is ordered and bought for the next season? 2. Here I am interested in the following case example: Now the tyre is charged with 200€ net in the report. a.) What happens if the invoice amount is only 150€ net? For this I would like to apply the VAT. Here I go d avon from the fact that the value added tax of €150 can be claimed (and not of €200). A total difference of €50 between the price in the report and the price actually paid. Can the insurance recover the €50? b.) What happens if the invoice amount is higher than indicated in the report? Can I claim the difference? 3. Can the value added tax also be claimed if something has been repaired in its own direction by: a picture as proof of repair is sent to the insurance company? About tips, hints, answers I am happy.
