What deductions can you claim on a Dutch salary as a Bulgarian resident?
Bulgarian residents earning a Dutch salary can claim several deductions to reduce their taxable income in the Netherlands, including the general tax credit, the employed person’s tax credit, and potentially the 30% ruling, depending on their residency status and employment structure. The Netherlands and Bulgaria have a bilateral tax treaty that prevents the same income from being taxed twice, which is the critical framework governing how these deductions interact across both countries. The sections below address each dimension of this question in detail, from treaty mechanics to social security obligations.
Does the Netherlands have a tax treaty with Bulgaria?
Yes, the Netherlands and Bulgaria have a double taxation treaty in force. This agreement determines which country has the right to tax specific types of income and ensures that a Bulgarian resident earning Dutch employment income is not taxed in full by both jurisdictions. Under the treaty, employment income is generally taxed in the country where the work is physically performed.
In practice, this means that if a Bulgarian resident works physically in the Netherlands, the Netherlands holds the primary right to tax that employment income. Bulgaria then applies an exemption or a tax credit mechanism to prevent double taxation on the same earnings. The specific method Bulgaria uses depends on the type of income and the provisions of its domestic law, but the treaty framework ensures that the total tax burden does not exceed what would be owed in either country alone.
For HR and finance leaders managing cross-border employment arrangements, understanding which country holds taxing rights over each income stream is the essential first step before any deduction strategy can be applied effectively.
What deductions reduce taxable income on a Dutch salary?
Dutch salary earners can reduce their taxable income through a combination of statutory tax credits and personal deductions. The most universally applicable are the algemene heffingskorting (general tax credit) and the arbeidskorting (employed person’s tax credit), both of which reduce the actual tax owed rather than the gross income figure. The amounts are income-dependent and adjusted annually.
Beyond these credits, the following deductions and allowances may apply depending on individual circumstances:
- Mortgage interest deduction: Available to residents who own property in the Netherlands and have a qualifying mortgage
- Pension contributions: Contributions to an approved Dutch pension scheme reduce taxable income in Box 1
- Study costs: Under certain conditions, costs for professional education may be deductible
- Healthcare costs: Specific qualifying medical expenses above a threshold may be deductible
- Travel deduction: Public transport costs for commuting to a Dutch workplace may qualify
For non-resident taxpayers, who include many Bulgarian residents working in the Netherlands, access to these deductions is more restricted. Non-residents only gain access to the full range of Dutch deductions if they qualify as partial non-resident taxpayers or elect to be treated as resident taxpayers. This distinction is examined further below.
Can a Bulgarian resident claim the 30% ruling in the Netherlands?
A Bulgarian resident can claim the 30% ruling in the Netherlands, but only if they are employed by a Dutch employer and meet specific eligibility criteria. The ruling is not available to remote workers who remain based in Bulgaria and are employed by a Bulgarian or non-Dutch entity. It applies to employees who are recruited from abroad and relocate to the Netherlands to work.
The 30% ruling allows qualifying employees to receive up to 30% of their gross salary as a tax-free allowance, intended to compensate for extraterritorial costs, the additional expenses of living and working abroad. To qualify in 2026, the employee must meet all of the following conditions:
- Be recruited or transferred from outside the Netherlands
- Have lived more than 150 kilometres from the Dutch border in the 24 months before starting employment
- Earn a salary above the statutory threshold (adjusted annually by the Dutch tax authority)
- Hold a valid employment contract with a Dutch payroll entity
The ruling has undergone phased changes in recent years. Since 2024, the tax-free allowance is capped at a percentage of the so-called Balkenende norm (the maximum salary for public sector executives), which limits the absolute benefit for high earners. For Bulgarian professionals relocating to the Netherlands, the 30% ruling remains one of the most significant expat tax deductions available, but it requires proper application through the Dutch Tax and Customs Administration (Belastingdienst) and is not automatically granted.
How does social security work when earning a Dutch salary from Bulgaria?
Social security contributions follow the country where the work is physically performed, not where the employee is resident. If a Bulgarian resident is employed by a Dutch employer and works in the Netherlands, they are generally subject to Dutch social security premiums, covering state pension (AOW), unemployment insurance (WW), and disability insurance (WIA). These contributions are deducted directly from gross pay through Dutch payroll.
The situation becomes more complex for employees who split their working time between the Netherlands and Bulgaria. EU regulations on social security coordination (Regulation 883/2004) determine which single country’s system applies when work is performed in more than one member state. As a general rule, if an employee performs a substantial portion of their work, typically 25% or more, in their country of residence (Bulgaria), they may fall under Bulgarian social security instead of Dutch.
This determination has significant financial implications. Dutch social security premiums are embedded in the Dutch payroll tax system and affect net take-home pay. Employers and employees in cross-border arrangements should obtain an A1 certificate, which formally confirms which country’s social security legislation applies and protects both parties from dual contributions.
What tax obligations remain in Bulgaria on Dutch employment income?
A Bulgarian tax resident is required to declare worldwide income in Bulgaria, including employment income earned in the Netherlands. However, thanks to the double taxation treaty between the Netherlands and Bulgaria, the same income is not taxed twice. Bulgaria applies the exemption with progression method for income taxed in the Netherlands, meaning the Dutch income is exempt from Bulgarian income tax but may still be taken into account when calculating the applicable Bulgarian tax rate on other income.
In practical terms, a Bulgarian resident who pays income tax in the Netherlands on their Dutch salary will typically owe no additional Bulgarian income tax on those same earnings. However, they must still file a Bulgarian annual tax return and declare the Dutch income, providing documentation of the tax paid in the Netherlands. Failure to declare foreign income, even exempt income, can result in penalties under Bulgarian tax law.
Bulgarian residents should also be aware that their tax residency status in Bulgaria is determined by Bulgarian domestic rules, not by where they work. Spending more than 183 days per year in Bulgaria, having a permanent home there, or having their centre of vital interests in Bulgaria are all factors that can establish Bulgarian tax residency, regardless of where their employer is based.
Should a Bulgarian remote worker register as a partial non-resident taxpayer in the Netherlands?
A Bulgarian resident who works remotely for a Dutch employer, remaining physically based in Bulgaria, is generally not subject to Dutch income tax, because the Netherlands can only tax employment income for work performed on Dutch soil. In this scenario, registering as a partial non-resident taxpayer in the Netherlands is unlikely to be necessary or beneficial.
However, the picture changes if the Bulgarian remote worker travels to the Netherlands to perform work, even periodically. Days physically worked in the Netherlands create Dutch taxable income, and if those days are significant, registration with the Belastingdienst may become obligatory. The threshold and reporting requirements depend on the total number of Dutch workdays and whether a tax treaty exemption applies.
For Bulgarian residents who do relocate to the Netherlands and take up physical employment there, the partial non-resident taxpayer status (also called the keuzerecht or qualifying non-resident status) can be advantageous. It allows access to Dutch personal deductions, such as mortgage interest and pension deductions, that would otherwise be unavailable to non-residents. Eligibility requires that at least 90% of the individual’s worldwide income is subject to Dutch income tax.
The decision to elect this status carries consequences in both countries and should be evaluated with a qualified cross-border tax adviser before any filing is made.
