Double Taxation Agreement (DTA)

In brief for employers

Double taxation agreements, or DTAs for short, are relevant for employers if employees work across borders, travel or work remotely in another country. They are intended to prevent the same income from being taxed twice in two countries. At the same time, they determine which state receives the right to tax and under what conditions.

In Remote Work Compliance, DTAs are particularly important because they are often related to tax residency, the 183-day rule, withholding tax and permanent establishment risk. However, a DBA does not solve all problems: social security, immigration, labor law and data protection must be reviewed separately.

Definition

A double taxation agreement is a bilateral agreement between two countries. It regulates how income and assets may be taxed in cross-border situations. For employees, it is often relevant whether employment income is taxed in the country of residence or in the country in which work is carried out. What is relevant for companies is, among other things, whether a permanent establishment is created or whether withholding taxes can be reduced.

DTAs are country specific. Therefore, HR should not work with a general DTA assumption, but should always check which specific agreement applies between the affected states.

Typical checks

These points are particularly important for employers when it comes to DBA questions:

• In which country is the person tax resident?
• In which country is the work physically carried out?
• Which working days are abroad?
• What role does the 183-day rule play in the specific agreement?
• Who is the employer and who financially bears the wage costs?
• Will the wages be charged to a local company, project or business location?
• Are there any local withholding tax or payroll obligations?
• Can the activity trigger a permanent establishment risk?

These questions show that DTAs do not only become relevant at the end of the year. They should already be taken into account when approving home office abroad, workation or international project stays.

Important distinctions

A DTA is the legal framework between two states. The tax liability for remote work describes the specific application to working days and income. The 183-day rule is often a DBA clause, but not the entire agreement. International Tax Compliance is the company-wide process that embeds DBA issues into a controlled workflow.

How Vamoz helps with DBA issues

Vamoz Remote Work Compliance helps companies capture the necessary information for a DBA check early and consistently. This allows HR, Tax and Global Mobility to decide more quickly whether a remote work or workation request can be treated as a standard case or whether an in-depth review is necessary.

Vamoz particularly supports:

• Recording of country, period, residence pattern and activity;
• Preliminary check as to whether tax issues such as DTA, 183 days or withholding tax are affected;
• Escalation to Tax for complex or recurring cases;
• Linking DBA checks to Remote Work Policy and Compliance Risk Assessment;
• Comprehensible documentation for later queries.
