If you are employed by a non-Swedish employer without a permanent establishment in Sweden, you can sign a social security agreement with your employer. This means that you agree to pay your own social security contributions in Sweden, called employer contributions, instead of your employer paying them. The same rules apply if you are a contractor working for a client without a permanent establishment in Sweden.
The requirement for entering into this type of agreement is that your employer does not have a permanent establishment in Sweden. A non-Swedish employer without a permanent establishment pays employer contributions at a lower rate than a Swedish employer. This is because the contributions a Swedish employer pays include general payroll tax, which is only paid by employers that are liable for tax in Sweden.
When you sign a social security agreement with your employer, you must register with the Swedish Tax Agency as an employer within two weeks of signing the agreement.
You register by filling in form SKV 4738. You can down load the form, which is in Swedish, via the link below:
You will be assigned a specific registration number to use when declaring and paying employer contributions. The number begins with 66 and should only be used in connection with employer contributions. You will also be assigned a specific tax account to which you must make these payments. Remember that you must not use your personal identity number (“personnummer”) or your personal tax account when you declare and pay employer contributions in connection with your social security agreement.
You will receive two separate tax account statements: one for your private tax account and one for the tax account connected to your social security agreement.
A social security agreement does not mean that your employer is free from responsibilities. You are simply agreeing to declare and pay employer contributions instead of your employer. If you do not declare and pay the employer contributions, the Swedish Tax Agency may instead require your employer to do so.
A non-Swedish employer without a permanent establishment in Sweden are from 1 January 2021 obliged to deduct tax from earnings and benefits paid for work carried out in Sweden. Your non-Swedish employer must register as an employer in Sweden – if it is not already registered – and must declare the tax deductions in a monthly PAYE tax return.
If you have a social security agreement with your employer (which means you have agreed to pay employer contributions in Sweden instead of your employer paying them), this agreement is unaffected by the new regulations. You must continue to declare and pay employer contributions using the specific registration number allocated to you. However, your employer must deduct preliminary tax from your income and declare these deductions to the Swedish Tax Agency in monthly PAYE tax returns.
If you have paid your own preliminary tax during the 2020 income year, you will probably be notified in January 2021 of the preliminary tax you are due to pay throughout the 2021 income year. Since you no longer have to pay your own preliminary tax, you will need to file a preliminary income tax return to avoid paying too much. You can file a preliminary income tax return using our e-service, or fill in a paper form. In the “Other information” (“Övriga upplysningar”) section of the return, write that your preliminary tax payments should be stopped because your non-Swedish employer will now deduct tax from your salary instead. Keep in mind that preliminary tax payments for 2021 start on 12 February 2021. If you are due to make a preliminary tax payment on 18 January 2021, you must pay it yourself as this is the final payment for the year 2020.
After you have registered and received your agreement registration number which begins with 66, you may submit your employer’s declarations.
The employer’s declaration must be submitted, and social security contributions paid, by the 12th of the month after your have received your employment income. If you, for example, have received salary and benefits in April then you need to submit the employer’s declaration and pay the employer’s contributions no later than 12 May.
In August and January, the deadline for submitting the employer’s declaration and paying the social security contribution is the 17th instead of the 12th if the employment income has been paid out in July (17 August) or in December (17 January).
Remember to submit and pay on time. You may have to pay late filing fees if you do not keep to the deadlines.
Remember that when paying your social security contributions (into your tax account), use your assigned agreement registration number which starts with 66, not your personal identity number or coordination number.
The easiest way to file a PAYE tax return every month is to log into “My pages” (“Mina sidor”) in the PAYE tax return e-service, using your Swedish e-identification.
You can also file a PAYE tax return using a printed form.
If you would like someone else to file your PAYE tax return, you can appoint a tax return agent. Your agent can submit your PAYE tax return via the e-service available through “My pages” (“Mina sidor”). Use the form “Application e-services tax return agent” (SKV 4809, in Swedish) to apply for registration of your PAYE tax return agent.
A has a social security agreement and will receive a salary of SEK 100,000 SEK. The rate of employer contributions, excluding general payroll tax, is 19.8% (for those born in 1955 or after).
The employer pays SEK 19,800 to A as compensation for employer contributions. A’s total salary will be SEK 119,800. The entire salary should not be used as the basis for employer contributions. The salary amount should be divided by 19.8% plus 100 percentage units, i.e. 1,198. The basis for employer contributions will be SEK 119,800 / SEK 1,198 = SEK 100,000. A must therefore pay employer contributions at 19.8% on a basis of SEK 100,000.
In this example, A’s taxable salary is SEK 119,800. When calculating income tax, A is entitled to deduct the full amount of employer contributions paid. The basis for employer contributions calculated in the example, SEK 100,000, is also the basis for calculating income tax.

At the end of the year, your employer must provide a statement of earnings and tax deductions with details of the full amount that has been paid, including both salary and any compensation for employer contributions. The statement must be made in connection with your personal identity number (“personnummer”).
The social security contributions that you have paid during the income year will be automatically deducted when you receive your Swedish income tax return. Your employment income (excluding the social security contributions paid) will be pre-printed on your tax return. It is therefore important that your employer submits your income statement.
You will be taxed on the net amount of salary and benefits, after employer contributions have been deducted. This net amount will also be the basis for your pensionable income. It is therefore important that your employer submits the statement of earnings and tax deductions.
Your final tax and pensionable income are shown in your final tax statement. Since pensionable income is the basis for calculating your pension, it is important to check that it has been correctly calculated.
You must notify the Swedish Tax Agency when the social security agreement no longer applies. Notify either by letter, or by using the same form as when applying for registration, Anmälan – om skyldighet att redovisa och betala arbetsgivaravgifter på egen lön, SKV 4738 and submit the relevant information in the ‘Other information’ section. Remember that you must continue to submit employer's declarations until you have received confirmation of your deregistration from the Swedish Tax Agency.
If you and your employer choose to end the social security agreement, your employer will be responsible for declaring and paying both deducted preliminary tax and employer contributions.
