Tax Adjustments in Cross-Border Matters
Cross-border matters regularly lead to tax adjustments. What matters is not only the domestic change, but its effect across borders.
If the correction is not mirrored abroad, double taxation follows.
One chain: primary adjustment, secondary adjustment, corresponding adjustment
In cross-border adjustment cases, the steps belong together.
The primary adjustment triggers secondary adjustments and, crucially, the question of a corresponding correction in the other state.
A purely domestic response often hardens double taxation instead of resolving it.
Germany and Switzerland offer different procedural instruments.
We select and combine them so that options remain open, timing is controlled, and the line holds in both states.
- Domestic remedies against authority-initiated changes (DE: objection; CH: objection and appeal stages)
- Domestic correction options in favour of the taxpayer where available
- Court proceedings where required
- Mutual agreement procedure under the Germany–Switzerland tax treaty
- Which steps are triggered on which side, and which in parallel?
- Which facts must be secured early to keep corresponding adjustments realistic?
- Is a mutual agreement procedure required, or can it be avoided?
- Which line must not contradict internationally?
We run cross-border tax adjustments as one coordinated procedural strategy across Germany and Switzerland.
The goal is to prevent or eliminate double taxation and restore international consistency.
