The most common mistake when reclaiming VAT from Germany is not an incorrect or incomplete receipt, but a request where a question from the German tax authority goes unanswered. The refund country can ask for clarification or additional documents during processing, and anyone who fails to respond in time will see their request—or part of it—rejected even though the underlying VAT was genuinely recoverable.
Beyond that first mistake, three other patterns recur consistently: requests submitted in fragments and therefore falling below the minimum threshold per period, a business use percentage that does not match actual travel, and a correction that is addressed too late because the rejection is only noticed after time has passed. None of these errors involve fraud; they are all matters of timing and administrative precision. an overview of how submission works per country shows what that process consists of.
No response to a question from the German tax authority
Once a request is submitted, that does not mean the matter is concluded. The Bundeszentralamt für Steuern may ask additional questions during assessment—for example about the nature of a cost item or a missing detail on an invoice. Those questions arrive via the same portal used for submission, and there is a deadline for responding.
Business owners who check the portal only once per quarter often simply miss that question because they do not know it is there. The result is a rejection that says nothing about the validity of the refund claim, but everything about when a response was given. Anyone submitting this themselves would do well to monitor the portal regularly rather than only at the time of submission.
Submitting requests in fragments
Each refund country applies a minimum threshold per period below which a request is not processed. Anyone submitting a separate request for each business trip or each month runs the risk that the VAT on those costs consistently stays just below that threshold, even though the same amount reviewed over a longer period would clearly exceed the limit.
The problem then lies not in the costs themselves, but in how they are categorised. By bundling receipts over a period into one request instead of separate submissions, less money remains structurally below the threshold. in a few questions see what is still outstanding gives a first indication of what can be bundled per year.
Misjudging the business use percentage
With mixed use—a vehicle driven both for business and private purposes, or an accommodation that is partly business and partly private—the business proportion must be determined. If that percentage is estimated too high, a follow-up question or partial rejection usually follows. If it is estimated too low, unnecessary money remains unclaimed.
The refund country tests this percentage against what is reasonable for the nature of the costs, and the rules differ per cost category and per country. Where there is doubt about what constitutes a reasonable percentage in a specific situation, it is advisable to consult a VAT specialist; that goes beyond the operational work of submitting and monitoring.
Correcting when it is too late
The most persistent form of this error is that it is only noticed after the rejection has already arrived. By that point, the refund country's question has long since been answered—or conversely, left unanswered—and there is often no room to put things right within the same submission. A new request for the same period is then not always possible.
That is precisely why monitoring is not a one-time action, but something that continues for as long as a request is being processed. Anyone doing this themselves must keep watch on the portal throughout the year; automating that monitoring prevents a question from the refund country from going unnoticed.
These four errors have one thing in common: they arise not because the VAT was non-deductible, but because the process around it goes wrong. answer to practical questions about the process goes deeper into what is precisely checked, and how we check invoices before they are submitted shows where that check focuses in practice. Anyone who wants to see what VAT from Germany is available for their own business can check that free of charge and without obligation.
