In recent years, Norway has seen an increasing number of foreign employees working temporarily in the country. To simplify the tax rules for this group, Norway has introduced a special withholding tax regime for salary income.
The regime means that certain foreign employees pay a fixed percentage of their salary income throughout the year, rather than being taxed under the ordinary rules involving tax returns, deductions, and tax assessments.
Although the regime is simpler than ordinary taxation, there are several conditions and limitations that both employers and employees should be aware of.
What is withholding tax on salary?
Withholding tax on salary is a special tax regime for foreign employees who have limited tax liability to Norway or who have recently become tax resident in Norway.
Under the regime, tax is calculated directly by the employer withholding a fixed percentage from the employee’s salary payments. The employee generally does not submit an ordinary tax return and does not receive a standard tax assessment for the income covered by the regime.
The purpose is to make it easier for individuals working in Norway for shorter periods to comply with their Norwegian tax obligations.
Who can use the withholding tax regime?
The regime is primarily intended for foreign employees who come to Norway to work for a limited period.
Typical examples include:
- employees relocating to Norway for a short-term work assignment;
- foreign employees working for Norwegian employers; and
- employees working in Norway for foreign businesses that have Norwegian tax obligations.
However, not all foreign employees are automatically eligible. It must be assessed whether the individual satisfies the conditions for the regime and whether they have income or circumstances that require taxation under the ordinary rules.
How does the taxation work?
Under the withholding tax regime, tax is calculated as a fixed percentage of gross employment income.
The employer withholds the tax through the ordinary payroll process and reports the information through the Norwegian a-melding reporting system.
An important difference compared with ordinary taxation is that employees generally cannot claim deductions for expenses that would otherwise be deductible. This means that the regime is often most suitable for individuals with:
- short stays in Norway;
- limited entitlement to deductions; and
- relatively straightforward employment arrangements.
For individuals with significant deductions or more complex financial circumstances, ordinary taxation may be more advantageous.
What is included in the tax base?
Withholding tax is calculated on gross employment income. This may include, among other things:
- ordinary salary;
- bonuses;
- holiday pay;
- benefits in kind;
- certain expense allowances; and
- other payments that are considered employment income for tax purposes.
The decisive factor is whether the payment or benefit is regarded as part of employment income under Norwegian tax rules.
Benefits in kind and reimbursements may be particularly challenging in practice, as the assessment depends on the nature of the benefit and how it is treated under the tax legislation.
Limitations of the withholding tax regime
Although the regime is simple, it is not suitable for everyone.
An employee may fall outside the regime if they, for example:
- receive other types of income that cannot be combined with withholding tax;
- become tax resident in Norway over time;
- wish to claim ordinary tax deductions; or
- need to apply specific tax relief provisions.
It must therefore be assessed on an individual basis whether withholding tax actually provides the most favourable tax outcome.
Significance of tax treaties
Tax treaties between Norway and other countries may affect where an individual has the right to be taxed.
Even if an employee is subject to Norwegian withholding tax on salary, the tax treaty between Norway and the employee’s home country may affect the allocation of taxing rights.
This is particularly relevant when considering:
- where the individual is tax resident;
- where the work is physically performed;
- the duration of the assignment; and
- who the employer is.
International employment arrangements therefore often require an assessment under both Norwegian domestic rules and the relevant tax treaty.
The employer’s responsibilities
The employer plays a central role in the withholding tax regime. The employer must, among other things:
- withhold the correct amount of tax;
- report salary information;
- use the correct tax withholding card; and
- handle changes in the employee’s tax status.
Incorrect use of the regime may result in additional tax assessments and liability for insufficient tax withholding.
For businesses employing foreign workers, it is therefore important to establish appropriate procedures for assessing tax obligations at the beginning of the employment relationship.
Can the employee leave the regime?
Under certain conditions, an employee may choose to leave the withholding tax regime and instead be taxed under the ordinary rules.
This may be relevant where ordinary taxation produces a more favourable result, for example because the employee is entitled to deductions that cannot be claimed under the withholding tax regime.
Leaving the regime may also become necessary if the conditions for participation are no longer satisfied.
Common mistakes when using withholding tax
In practice, challenges often arise because:
- employees choose the regime without considering their entitlement to deductions;
- employers use the wrong tax withholding card;
- the duration of the stay is not assessed correctly;
- other income is not taken into account; or
- benefits in kind are treated incorrectly.
An early assessment of the tax position can therefore be crucial to avoiding unexpected tax consequences.
Conclusion
Withholding tax on salary is a simplified tax regime that can be highly practical for foreign employees undertaking temporary work in Norway. At the same time, the regime has important limitations, particularly because employees generally cannot claim ordinary tax deductions.
For employers, correct administration is essential to avoid errors in payroll withholding and reporting. For employees, it is crucial to assess whether withholding tax actually results in a lower overall tax burden compared with ordinary taxation.
For international employment arrangements, both employers and employees should therefore review the applicable tax rules at an early stage—before the employment relationship begins.
