This guidance concerns the provision of the Nordic Tax Treaty on cross-border commuters, and the related special issues.

Chapter 7.2 has been updated, as deductions of insurance contributions paid abroad are discussed in more detail in the Tax Administration guidance Deduction of expenses in international situations. Some details have been clarified and a new example concerning working from home has been added. Chapter 8 on procedures has been edited for conciseness.

1 Introduction

This guidance concerns the rules set for cross-border commuters in the Nordic tax treaty (26/1997) and the effects these rules have on the tax assessment of an individual who works in a border municipality.

The provision on cross-border commuters can be applied to wage income if the individual in question lives in a municipality located next to the border between Finland and Sweden or Finland and Norway and works in another municipality located next to the same border in the other country. The individual must also regularly stay in their permanent residence in their country of residence. If these conditions are met, the wage income the individual earns for cross-border work is only taxed in the individual’s country of residence. The tax authority of the country where the work is done has the right to assess whether the provision is applicable.

The taxation of cross-border commuters is discussed in protocol VI of the Nordic tax treaty (available in Finnish and Swedish, link to Finnish).

2 Scope of application of the provision on cross-border commuters

The provision on cross-border commuters applies to wage income received for personal work. The provision is applicable to wages and salaries paid by both public authorities and private employers. The provision is not applicable to artist’s or athlete’s income, social benefits, pensions or business income.

Example 1. An individual living in Tornio in Finland works as a nurse for the Swedish municipality of Haparanda. He returns to his permanent residence in Tornio every day after his shift in Haparanda ends. The individual is considered a cross-border commuter and he pays tax on his pay to Finland.

Example 2. A hairdresser lives in Haparanda, Sweden and runs a hair salon in Tornio, Finland. She visits her establishment in Tornio every day. The hairdresser is not considered a cross-border commuter, because the provision on cross-border commuters is not applicable to business income.

The provisions on cross-border commuters can be applied to income received from a personnel fund if the income received is based on work the cross-border commuter has done in a border municipality. The taxation of income received from a personnel fund is discussed in the Tax Administration’s detailed guidance on the taxation of income received from a personnel fund (available in Finnish and Swedish, link to Finnish).

The provision on cross-border commuters does not apply to trade income. Income such as family caregiver’s fees and foster care provider’s fees are considered trade income and the provision therefore cannot be applied to them.

3 Home municipality and work municipality

An individual is considered a cross-border commuter if they live in a municipality located next to the border between Finland and Sweden or the border between Finland and Norway and they work in another municipality next to the same border in the other country. The individual’s home municipality and their work municipality on the other side of the border do not need to be neighbouring municipalities.

Based on Article 3, paragraph 2 of the Nordic tax treaty, concepts and phrases not explicitly defined in the treaty will be primarily interpreted based national tax legislation. The tax treaty protocol on cross-border commuters does not define the phrase “living in the municipality”. Therefore the definition of living in the municipality must be based on national tax legislation.

According to Finland’s legislation governing the tax assessment of resident taxpayers who are natural persons, the taxpayer’s municipality of residence is the municipality where they had a permanent place of residence as defined in the act on registered domiciles in the end of the year previous to the tax year (§ 5, section 1, act on assessment procedure (Laki verotusmenettelystä 1558/1995)). Therefore, in terms of tax assessment, an individual’s municipality of residence cannot change during the tax year. Because of this, the individual is not yet considered a cross-border commuter during the year when they move in to the border municipality. However, an individual moving away from a border municipality is considered a cross-border commuter for the rest of the tax year, if the other conditions of the provision are still met.

Example 3. An individual has moved within Finland from Kemi to Tornio on 1 March and starts working in Haparanda, Sweden later during the same year. The provision on cross-border commuters cannot be applied on the individual’s pay until the start of the next year.

In Sweden and Norway, an individual’s municipality of residence is considered to be the municipality in which the individual resided on 1 November of the year previous to the tax year (Inkomstskattelag 65 kap. 3 § 2 st. and Lov om skatt av formue og inntekt § 3-1).

Border municipalities between Finland, Sweden and Norway 

Border municipalities between Finland, Sweden and Norway
Municipalities on the border between Finland and Sweden Municipalities on the border between Finland and Norway
Enontekiö, Kolari, Muonio, Pello, Tornio, Ylitornio Enontekiö, Inari, Utsjoki
Haparanda, Kiruna, Pajala, Övertorneå Karasjok, Kautokeino, Kåfjord, Nesseby, Nordreisa, Storfjord, Sör-Varanger, Tana

Example 4. The Finnish municipality of Enontekiö is bordered by Sweden and Norway. An individual living in Enontekiö can therefore work as a cross-border commuter in both Swedish and Norwegian border municipalities. An individual living in Tornio can only work as a cross-border commuter in Sweden.

Example 5. An individual living in Inari, Finland can work as a cross-border commuter in the Norwegian municipality of Kåfjord even though Inari and Kåfjord do not share a border.

Example 6. An individual living in Utsjoki, Finland is working in Kiruna, Sweden. The provision on cross-border commuters cannot be applied because Utsjoki is not located next to the border between Finland and Sweden.

4 Application of the provision on cross-border commuters when moving to and from Finland

When a non-resident taxpayer who has lived abroad moves to Finland, their municipality of tax domicile is considered to be the municipality where they first started living in after their move. If such an individual starts living in a Finnish border municipality as defined in the provision on cross-border commuters, they can be considered a cross-border commuter from the moment of their move to Finland if all the other conditions are also met.

If an individual moves away from Finland, their municipality of tax domicile is considered to be the municipality where they resided before they moved abroad. As long as the individual is treated as a resident taxpayer in Finland, this municipality is considered their municipality of tax domicile. If the individual can prove that their country of residence as meant in the provision on cross-border commuters is Sweden or Norway, the provision on cross-border commuters can be applied to them as soon as the other conditions are met.

Example 7. An individual living in Tornio, Finland moves to Haparanda, Sweden in June and continues working in Tornio. After the move, the individual’s permanent residence and home is in Sweden. The individual is considered a cross-border commuter immediately after their move if they present a certificate of residency and tax liability in Sweden provided by the Swedish tax authority.

5 Stay in country of residence

In order to be considered a cross-border commuter in accordance with the provision on cross-border commuters, the individual must regularly stay in their country of residence. Staying is considered to be regular when, in normal circumstances, the taxpayer stays in their permanent residence in their country of residence at least once a week, and these stays last at least two days and one night. A week refers to the time between a Monday and a Sunday. Even a part of a day is treated as a full day. In this context, the “normal circumstances” refer to the taxpayer’s habitual stays in their home in their country of residence when not working. Habitual stays in the country of residence are not interrupted by temporary stays elsewhere due to special circumstances, such as extra work or holidays.

Example 8. A mine worker lives in Kolari, Finland and works in Kiruna, Sweden for a local mining company. He stays in a rental apartment in Kiruna for the duration of his work week, from Monday to Friday. On weekends, he stays at his permanent residence in Kolari. The individual is considered a cross-border commuter and he pays tax on his pay to Finland. He must give a report on his work abroad on a tax return form.

If an individual does not stay at their permanent residence in their country of residence at least once a week, the provision on cross-border commuters cannot be applied.

Example 9. A mine worker lives in Kolari, Finland and works in Kiruna, Sweden for a local mining company. She stays in a rental apartment in Kiruna for the duration of her two-week work periods. After each work period, she gets a week off, which she spends at her permanent residence in Kolari. The individual is not considered a cross-border commuter because she does not stay in Finland every week. She must pay tax on her pay to Sweden. She must give a report on her work abroad on a tax return form. The wage income she has received from Sweden is taken into account in her Finnish tax assessment in accordance with the progressive exemption method. For more information on the taxation of work conducted abroad, see the Tax Administration guidance articles Taxation of income earned abroad and Relief for international double taxation.

6 Cross-border commuter’s insurance

6.1 Cross-border commuters living in Sweden or Norway

In general, employees must be insured in the country where they work, even if the tax treaty provisions on cross-border commuters prohibit the taxation of the employee’s pay in that country.

Accordingly, cross-border commuters who work in Finland generally carry Finnish national sickness insurance. The Finnish employer must pay the employer's health insurance contribution, based on the cross-border employee’s pay. The employer must also withhold the healthcare contribution and earned-income contribution from his or her pay. For more information on the contributions required of the employer and the workers, see Health insurance contributions in international employment situations, the Tax Administration’s in-depth guide.

Pension insurance contributions and accident insurance contributions must be paid to Finland when the work is done here in the employ of a Finnish employer. Likewise, the parts payable by the individual worker of the pension insurance and unemployment insurance contributions must be withheld from their pay. The employer is not liable to withhold and pay pension and unemployment insurance contributions or healthcare and earned-income contributions if the employee can present an A1 or other such certificate they have received from another country.

More information on pension insurance and the A1 certificate is available from pension providers and the Finnish Centre for Pensions. For further information on national health insurance, contact the Social Insurance Institution (Kela; FPA-Folkpensionsanstalten) or visit their website.

6.2 Cross-border commuters living in Finland

In general, cross-border commuters who work in another Nordic country are covered by the national sickness insurance system of that country. From this, it follows that the amounts of the insurance premiums or contributions depend on the provisions of that country’s legislation.

7 Special situations

7.1 Working in a border municipality and outside the border municipalities

In general, wage income (including sick pay, bonuses, etc.) is considered to be based on work done in the municipality where the employee usually works. If the employee relocates outside the border municipality for a certain period of time, the wages and other wage-like compensation paid for this work period are considered to be based on work done in this other municipality. In this case, the income is divided into cross-border commuter’s income and income from work conducted outside the border municipalities according to the proportion of work days conducted at each location. A similar division is made if the cross-border commuter works partly from home.

Example 10. A bus driver living in Haparanda, Sweden starts his shift at a bus depot in Tornio, Finland. His bus route is Haparanda – Tornio – Keminmaa – Kemi twice an hour. The provision on cross-border commuters is applicable to work done in the Tornio area. The provision is not applicable to work done in the Keminmaa and Kemi areas, and the wages earned for the work done in these municipalities is taxable in Finland. The Nordic tax treaty prohibits Finland from taxing work done in Haparanda. The right to tax the bus driver’s work is divided between Sweden and Finland based on his work hours in different municipalities.

Holiday pay and holiday compensation are divided between cross-border commuter’s pay and other pay according to whether they are paid based on work done in a border municipality or outside the border municipalities. This division is calculated for the period during which the income was accrued.

Example 11. An individual living in Pajala, Sweden works for a Finnish company. During the holiday credit year, he has worked five months in Kolari and seven months in Rovaniemi. The company pays him €3000 in holiday pay and holiday bonus. Of this amount, €1250 (3,000x5/12) is cross-border commuter’s income and €1750 (3,000x7/12) is wage income subject to tax in Finland.

Example 12. An individual living in Enontekiö, Finland works as a cross-border commuter for a company located in Kiruna, Sweden. In addition to working at the company’s premises in Kiruna, every month the employee also works from their home in Finland. The employee’s wage income is divided into cross-border commuter’s income and income received from work conducted in Finland according to the proportion of the number of work days conducted in Sweden to the number of work days conducted in Finland. The work condcucted in Kiruna is subject to the provisions on cross-border commuters, meaning that this portion of the income is taxed in Finland only. The work conducted from home in Finland is not subject to the provisions on cross-border commuters. However, Sweden does not have the right to tax wages paid for remote work conducted in Finland, meaning that this portion of the income is also taxed in Finland only.

However, the provisions on cross-border commuters can be applied on pay received for a business trip outside the border municipality if the trip was relevant to the cross-border commuter’s work, was done for the same employer and lasted for no longer than a few days.

Example 13. An individual working in a border municipality must travel annually to Helsinki to the company’s main office for a training session lasting a few days. The provisions on cross-border commuters are applicable to wages earned during a business trip like this.

7.2 Deducting foreign insurance contributions

According to § 96, subsection 1 of the act on income tax (Tuloverolaki 1535/1992), taxpayers can deduct statutory employee’s pension contributions, unemployment insurance contributions, and daily allowance contributions of health insurance from their net taxable earned income. Contributions paid abroad are also tax-deductible if they correspond to the Finnish contributions. The deductibility of insurance contributions paid abroad is discussed in more details in chapter 3.5 of the Tax Administration guidance Deduction of expenses in international situations.

7.3 Taxation in Finland of foreign employer’s contributions

When an individual is working abroad, their pay, wage supplements and reimbursements for expenses are determined by the legislation of the country where the work is done. However, the pay received by a cross-border commuter is taxed in accordance with the legislation of their country of residence. Therefore, the taxability of the income and reimbursements received by cross-border commuters living in Finland is determined by Finnish legislation.

Example 14. The Swedish employer of a cross-border commuter living in Finland has paid the commuter kilometre allowance.A part of the allowance has been added to the commuter’s wage income. The employer has also given them a certificate of the pension insurance contributions paid to Sweden. In their tax return, the commuter claims a tax deduction for the pension insurance contributions and the kilometre allowance added to their pay.

Whether the kilometre allowance is subject to tax is determined in Finland according to § 71 of the Finnish act on income tax (Tuloverolaki 1535/1992) and the annual decision of the Tax Administration on the tax-exempt reimbursements of travel expenses. The commuter must therefore provide give a report on the grounds for the kilometre allowance (driver’s log, travel invoice, etc.) that states the time of the trip, the route taken, and the purpose of the trip. In addition, they must provide a statement given by their employer or pension provider on whether the pension insurance contributions withheld from their pay are statutory contributions or payments for collective additional pension insurance in order to determine whether the pension insurance contributions are tax-deductible.

8 Guidance on procedures

8.1 Cross-border commuters living in Finland

Foreign employers are not liable to withhold and pay Finnish tax on wages they pay to a cross-border commuter living in Finland. The cross-border commuter must therefore take care of the taxes by requesting from the Tax Administration a tax prepayment for their wage income.

A cross-border commuter living in Finland must usually provide the tax authorities of their country of work with a certificate stating their residency and tax liability. The certificate is marked with the municipality where the taxpayer lived in the end of the previous year.

Foreign employers are not liable for reporting the wages paid to cross-border commuters to the Incomes Register. The cross-border commuter must therefore report their income, as well as any insurance contributions paid abroad on the income, on their tax return.

For more details on the procedures of requesting tax prepayments and the certificate of residence and on filing income on the tax return, see the following instructions: Cross-border commuter – You live in Finland and work in Norway or Sweden - vero.fi.

8.2 Cross-border commuters living in Sweden or Norway

8.2.1 Taxation of cross-border commuter’s income

If a cross-border commuter lives in Sweden or Norway and works in a Finnish border municipality, they must provide their employer with a tax-at-source card or tax card calculated for this work. In order to get a tax card or tax-at-source card, the cross-border commuter must present a certificate of residency and tax liability provided by the tax authority of their country of residence. This certificate must state the taxpayer’s municipality of tax domicile.

Cross-border commuters working in a Finnish border municipality pay to Finland the health insurance contribution and earned-income contribution from their wages. These contributions do not need to be paid if the cross-border commuter present the Tax Administration with a certificate (A1) proving that they are not covered by Finnish health insurance.

The cross-border commuter’s employer reports the wages they pay to the commuter to the Incomes Register on a payroll report. Cross-border commuters who are resident taxpayers receive a pre-completed tax return from Finland, and they must check the details on it and make corrections if necessary. Income subject to taxation at source received by non-resident taxpayers is not included in the pre-completed tax return and it does not need to be reported. 

For more details on the procedures of requesting a tax card or a tax-at source card and the certificate of residence required for a tax card and on filing income on the tax return, see the following instructions: Cross-border commuter – You live in Finland and work in Norway or Sweden - vero.fi.

8.2.2 Taxation of income that is not cross-border commuter’s income

If an individual living abroad receives income from Finland that is not cross-border commuter’s income, this other income is taxed in Finland if Finland has the right to tax this income under a tax treaty.

Non-resident taxpayers must pay tax at source to Finland on any income received from Finland that is not considered cross-border commuter’s income. Non-resident taxpayers can request taxation in accordance with the act on assessment procedure (Laki verotusmenettelystä 1558/1995) instead of taxation at source, in which case their income is taxed based on the progressive State tax and the average municipal tax rate. The income that the taxpayer has earned as a cross-border commuter as well as their other income are taken into account when determining the tax rate on their earned income. More information on the taxation of non-residents can be found in the Tax Administration’s guidance Taxation of employees from other countries.

Resident taxpayers must pay tax to Finland on any income that is not considered cross-border commuter’s income in accordance with the act on assessment procedure (Laki verotusmenettelystä 1558/1995). Furthermore, they must request a tax card for their income. Wage income received as a cross-border commuter is not taken into account when calculating the tax rate on other income.

8.3 Transfer of paid-in tax amounts between Finland, Norway and Sweden

There is an agreement known as the TREKK Treaty between Denmark, Finland, Iceland, Norway and Sweden, making it possible for Nordic tax authorities to transfer amounts of tax money between them, and making it easier for workers and employers to pay taxes to the Nordic country that has the right to tax the worker’s wages. In a situation where taxes have been withheld from a cross-border commuter’s wage income to the Nordic country where he or she works, the paid-in amounts can be transferred to his or her Nordic country of residence. For more information, see Do you work in Sweden, Denmark, Norway or Iceland? – Your taxes can be reassigned to the Nordic country that has the taxing rights and The Nordic Agreement Concerning the Collection and Transfer of Tax.
