Within a two-hour train ride, you can pass through three different language zones, completely different cultural landscapes, and what feels like twenty-six distinct countries when it comes to local law —especially if you require US tax return preparation to keep peace with the IRS—and attempting a DIY tax return can become a costly gamble.
In a situation whereby even making a filing error leads to being stuck with assessment that is unfavourable to you and attracting hefty fines, working with an experienced tax consultant becomes your most reliable protection in 2026.

High-Value Childcare and Educational Splits
In light of the introduction of tax payments for married individuals from 2026 onwards, decisions regarding which parent should take up the child dependents.
The NOV “Trap” for B-Permit Holders
