Identifying risks at the interface between customs and VAT and ensuring processes are properly integrated

Indirect tax & supply chain

Properly combining customs and VAT processes is crucial to international businesses. Well aligned processes are essential for correctly handling customs and VAT in the international movement of goods, ensuring efficiency and preventing errors. Errors at this interface often go unnoticed for a long time – but lead to significant financial risks and non-compliance. Unclear responsibilities and flawed process flows have a direct impact, particularly in cross-border trade. The following article highlights typical interfaces and areas of risk and explains why consistently aligning customs and VAT is becoming increasingly important.

Federal Fiscal Court ruling: Fees for binding rulings under section 89(2) and following of the Fiscal Code

BFH-Insights

“Tax offices and the Federal Central Tax Office may upon request provide advance rulings on the treatment of precisely defined, as yet unrealised circumstances if this is of particular interest due to the existence of significant tax implications”, states section 89(2) sentence 1 of the Fiscal Code [Abgabenordnung–AO]. Taxpayers that are planning a restructuring which they have not yet carried out, for instance, may obtain legal certainty as to what the consequences of this will be with respect to the tax authority. The Federal Fiscal Court [Bundesfinanzhof–BFH] has now again taken a position on the requirement to pay a fee for the advance ruling in complex cases (II R 38/23).

Federal Tax Court judgement: Cross-border commuter rules in German double taxation treaties

BFH-Insights

Cross-border commuter rules are found in several German double tax treaties (DTTs) [Doppelbesteuerungsabkommen-DBA] with neighbouring states, particularly those with France, Austria and Switzerland. Other DTTs with such states are not equipped with such a rule. The cross-border commuter rules lead to taxation outcomes that diverge from the otherwise customary rules on "employment" under article 15 of the 2025 OECD Model Convention [OECD-Musterabkommen-OECD-MA] 2025/article 14 of the 2026 German Model Treaty. The Federal Tax Court [Bundesfinanzhof-BFH] has now again decided on the cross-border commuter rule under the DTT with Switzerland (file ref. VI R 31/24).

Federal Fiscal Court ruling: Refund of withholding taxes in the absence of German taxing rights

BFH-Insights

Income taxes are frequently levied through withholding taxes in both purely domestic and cross-border contexts. The withholding of withholding tax on capital income (sections 43 and following of the Income Tax Act [Einkommensteuergesetz-EStG]) is (also) final in many cases even for taxpayers subject to resident tax liability (section 43(5) sentence one). Furthermore, in the taxation of taxpayers subject to non-resident tax liability (section 1(4); section 2 of the Foreign Transactions Tax Act [Außensteuergesetz-AStG]; section 2 of the Corporate Income Tax Act [Körperschaftsteuergesetz-KStG]), the “finality effect” of such withholding taxes often precludes the possibility of assessment (section 50(2) sentence one of the Income Tax Act; section 32(1) of the Corporate Income Tax Act). The possibility of obtaining a refund of overpaid withholding taxes is particularly essential for taxpayers subject to non-resident tax liability. The option, in this case, instead of challenging the underlying self-assessment under section 50d(1) sentence 2 of the Income Tax Act (old version) (now: section 50c(3) sentence 1), to obtain a refund has been denied by the sixth chamber of the Federal Tax Court [Bundesfinanzhof-BFH] (file ref. VI R 12/24). However, the sixth chamber of the Federal Tax Court has provided for a transitional provision.

Federal Fiscal Court decision: Time limits in the taxation of private disposal transactions (section 23 of the Income Tax Act)

BFH-Insights

Concerning tax-related time limits, the Fiscal Code [Abgabenordnung–AO] basically refers back, in section 108,  to sections 187 to 193 of the Civil Code [Bürgerliches Gesetzbuch–BGB]. In section 109 it also addresses the extension of these time limits and, in section 110, restoration to the previous status (restitutio in integrum). But time limits also play a role in the substantive provisions of income tax law. In particular, section 23 of the Income Tax Act [Einkommensteuergesetz–EStG] on “private disposal transactions” contains this kind of time element. Depending on the asset concerned, the time limits of one or ten years apply. How these are to be calculated is therefore of considerable importance for taxability. The Federal Fiscal Court [Bundesfinanzhof–BFH] has reaffirmed its settled case law on this point (IX B 24/26).
