How the Basel-Landschaft income tax process works

1. Discovery call

A 20-minute call to clarify your residence in canton Basel-Landschaft, your income sources, asset structure and any US or German tax connections. We confirm that your case fits our cross-border and private client focus.

2. Engagement & onboarding

You receive a joint engagement pack clearly separating:

  • The Basel-Landschaft income and wealth tax mandate with Sesch TaxRep GmbH
  • Where applicable, the US mandate with Sesch USA LLC and/or the German mandate with Sesch Group GmbH Wirtschaftsprüfungsgesellschaft
  • Data protection, information sharing and billing principles

3. Unified intake & secure upload

We use a single intake questionnaire and secure document portal for all jurisdictions. Salary statements, bank and portfolio reports, pension documents, equity compensation data and real estate details are collected once and allocated internally to the Swiss, US and German teams.

4. Draft returns & cross-border alignment

The Basel-Landschaft team prepares draft income and wealth tax returns, while the US and/or German teams prepare their filings. We coordinate sourcing, foreign tax credits and treaty positions so that all returns are consistent and defensible.

5. Review, sign-off & filing

We walk you through the key Basel-Landschaft figures (taxable income, net wealth, effective rates) and how they interact with US or German outcomes. After you approve, we file the Basel-Landschaft returns electronically or by post and monitor assessments and deadlines.

6. Invoicing

Separate invoices are issued by each legal entity (Swiss, US, German). On request, we can align billing in CHF, USD or EUR and provide an overview of the total engagement cost.

Who we typically work with in Basel-Landschaft

  • Executives with international roles and equity compensation packages
  • US citizens/green card holders or German taxpayers living in canton Basel-Landschaft
  • Entrepreneurs, partners and significant shareholders with cross-border structures
  • Families with substantial portfolios, holdings or property and wealth tax exposure

Purely domestic Basel-Landschaft salary-only cases without cross-border or wealth tax complexity are generally outside our core focus and better served by mass-market providers.
