Sick leave in Sweden 2026: Key Rules, SGI, Karensavdrag and Rehabilitation Chain explained

Sweden is famous for a strong welfare model, but when you are the one who gets sick, you do not need a slogan, you need clarity. In this post, I will explain how sick leave in Sweden works in 2026, step by step, in normal language. If you are employed, self-employed, new in Sweden, or just confused by the letters from authorities, this guide will help you understand what happens, who pays you, and what you need to do to protect your income.

You will learn the basics of the system, including the well-known rehabiliteringskedjan, what your employer is responsible for, what you must handle yourself, and how the payment structure usually develops over time. I will also explain the practical reality in 2026, where most communication is digital, but proper medical documentation and correct reporting are still absolutely essential.

How sick leave in Sweden works in 2026

The Swedish social security system is often recognized globally for focusing on both individual stability and shared responsibility. A central part of this system is financial protection for workers who cannot perform their duties due to illness or injury. If you live or work in Sweden, understanding sick leave is not only about following formal procedures. It is a key element of protecting your income and maintaining financial stability when your health forces you to slow down.

In 2026, the system continues to develop, mainly through improved digital tools and more efficient administration. However, the core structure has not changed. Sweden still applies a structured assessment model designed to support recovery and encourage a return to working life when possible. This model, known as rehabiliteringskedjan, sets clear checkpoints for evaluating your work ability over time. In the following sections, I will explain the main rights, obligations, and financial rules that define the Swedish sick leave process today.

The philosophy behind sick leave in Sweden in 2026

To make sense of the sick leave rules in Sweden, it helps to first understand the idea behind the system. At the core is the “Work First” principle, in Swedish called arbetslinjen. This principle means that the social insurance system is mainly designed to support you in getting back to work, not to provide long-term “passive” compensation as a default. In other words, the focus is on recovery plus a realistic plan for returning to work, step by step, when possible.

In practice, sick leave in Sweden works like a partnership. Several actors are involved, and each one has responsibilities that become important at different points during a sickness period: you (the employee), your employer, your healthcare provider, and the Swedish Social Insurance Agency, Försäkringskassan. The system expects cooperation between these parties, and in 2026 this is often handled through digital communication, certificates, and structured follow-ups.

The system is financed mainly through employer-paid contributions, called sociala avgifter, as well as general taxation. In return, workers receive a safety net that can replace a significant part of their income when a doctor confirms they are not fit to work. But this support also comes with clear conditions. You are usually expected to actively participate in your recovery and rehabilitation, and to provide the right documentation on time, because eligibility is closely tied to medical proof and ongoing assessments.

Phase 1: The employer period (Days 1 to 14)

When you get sick as an employee, the first two weeks are handled mainly between you and your employer. This stage is often called the “employer period,” and it is regulated by the Sick Pay Act, sjuklönelagen. During days 1–14, your employer is usually the one who pays compensation, and Försäkringskassan normally does not pay anything at this point, unless you are unemployed or self-employed (then the setup can look different).

Reporting and your first day off

The process starts the moment you understand you cannot work. In Sweden, you are expected to report your sickness as soon as possible on the first day of absence. This is not just a “nice to have”, it is important because it officially starts the sick pay period. If you do not report your illness on day one, your employer is usually not required to pay sick pay for the days before you informed them.

In many workplaces in Sweden in 2026, this reporting is done digitally, for example through HR systems like Primula or PA Web. Some employers still use simpler methods, like calling your manager or sending an email, but the main rule is the same: your employer needs the notification immediately. If you work in the public sector or in large organizations (including universities), you may also need to report your absence in two places, for example both to your manager and to a central payroll system, so the salary deductions and sick pay are handled correctly.

The sick leave deduction: karensavdrag

One of the most important details in the first phase of sick leave is the sick leave deduction, called karensavdrag. Sweden introduced this model on January 1, 2019, replacing the old “waiting day” system, karensdag. The goal was to make the system more fair, especially for people with irregular schedules, shift work, or very long working days.

Under the old rules, the financial impact could be very uneven. If you missed one 12-hour shift, you lost much more money than someone who missed a 4-hour shift, even if both were “sick for one day.” The current karensavdrag model is designed to standardize that loss, so the deduction becomes more similar across different working patterns.

Here is the key rule: the deduction is calculated as 20% of the sick pay you would normally receive during an average work week.

The calculation usually follows this logic:

• First, the employer calculates your sick pay, which is typically 80% of your regular salary (and certain benefits) during sick leave.
• Then, they calculate what your average weekly sick pay would be.
• Finally, the karensavdrag equals one-fifth (20%) of that weekly average.

So even though it is connected to your first sickness period, it is not simply “one full day without pay.” In 2026, most payroll systems handle this automatically, but it is still worth understanding, because it explains why the first deduction may look different than people expect.

Even if you only work a few hours on the day you become sick, the deduction is still based on the weekly average. In other words, karensavdrag does not “shrink” just because you got sick late in the day. If the sick pay for that first day is lower than the total deduction, the remaining part of the deduction is moved forward and taken from your next sick day within the same sickness period. At the same time, there is an important limit: the deduction can never be higher than the total sick pay you receive during the 14-day employer period.

The 80% sick pay rule: sjuklön

From day 2 of your illness (or immediately after the deduction has been applied) up to day 14, your employer pays sick pay, called sjuklön. In most cases, this is 80% of what you would have earned if you were working.

This is not only your base salary. It can also include regular employment benefits and common salary additions, for example recurring bonuses, shift pay and evening or weekend supplements (often called OB-tillägg), and other standard additions that are normally part of your pay.

For the employer, sick pay is a real and direct cost, so they are allowed to make sure the sick leave is based on an actual reduced work ability. In practice, the employer has both the right and the responsibility to assess work capacity. The question they are trying to answer is basically: Does this illness stop the employee from doing their regular job, or from doing other temporary tasks the employer can reasonably offer?

Medical certificate during days 1 to 14

During the first week of sickness, your own notice and statement is usually enough. But from day 8 (calendar day 8) of the same sickness period, you normally need to provide a doctor’s certificate, called läkarintyg, to your employer. This is not optional. It is a legal requirement for the employer to continue paying sjuklön.

In 2026, the certificate is often handled digitally through Swedish healthcare systems, but what matters is still the content: the läkarintyg should explain how your condition affects your ability to work. At the same time, you have an important right: your employer does not have to know your exact diagnosis. The certificate should focus on work limitations, not private medical details.

There is also an exception you should know about. If you have many short sick leaves, or if the employer has specific reasons to request it, they can require a medical certificate from day one, called förstadagsintyg. If your employer requests a certificate and you do not provide it, they are usually not legally required to pay sick pay for that period.

Phase 2: Transition to Försäkringskassan (from day 15)

If your illness continues longer than 14 days, the employer’s obligation to pay sjuklön ends. From day 15 onward, the responsibility for financial compensation moves to the state, through Försäkringskassan. This is an important shift, and it requires specific administrative steps from both the employer and the employee.

The employer’s obligation to report

If you are still sick after day 14, your employer must inform Försäkringskassan that the sickness continues. This report must be submitted no earlier than day 15 and no later than day 21 of the same sickness period.

This step is crucial because it formally activates the next phase. Without this report, you cannot properly apply for sjukpenning (sickness benefit). If the employer submits the report late, your payments from Försäkringskassan may also be delayed. In 2026, this reporting is usually handled digitally through employer systems connected to the agency.

Your application for sjukpenning

After your employer has reported your continued sickness, you must personally apply for sickness benefit. The easiest way to do this is through Försäkringskassan’s online service, Mina sidor.

In your application, you will need to provide:

• Information about your work situation
• Details about your income
• Information about your medical condition and reduced work ability

A valid medical certificate must be connected to your application. In most regions in Sweden, doctors send the certificate digitally to Försäkringskassan. You can usually see your certificates in the healthcare portal 1177 Vårdguiden, under Mina intyg, and confirm that they are shared with the agency.

In 2026, most of this process is digital, but it is still your responsibility to make sure the certificate is correct and submitted on time.

The re-illness rule: återinsjuknanderegeln

Sweden also has a special rule for people who return to work but become sick again shortly after. If you go back to work and then fall ill again within five calendar days, the new sickness is treated as a continuation of the previous period. This rule is called återinsjuknanderegeln.

This has two important consequences:

1. No new deduction
   If a full karensavdrag was already made during the first sickness period, a new deduction is not applied.
2. The days are combined
   The sickness days are added together. For example, if you were sick for 12 days, then worked for 3 days, and then became sick again, the employer will only pay sick pay for 2 additional days. After that, the total reaches 14 days, and the responsibility moves to Försäkringskassan (12 + 2 = 14).

This rule prevents the system from “resetting” every time someone briefly returns to work, and it creates more continuity in longer or unstable recovery situations.

Sickness Benefit Qualifying Income: SGI

When you receive compensation from Försäkringskassan, the amount is mainly based on your Sickness Benefit Qualifying Income, called sjukpenninggrundande inkomst (SGI). Think of SGI as a calculated number that represents your expected yearly work income in Sweden. In 2026, SGI is still one of the most important concepts to understand, because it affects how much support you can get if you are on long-term sick leave.

How SGI is calculated

For most employees, SGI is based on your current gross salary. If your salary is stable and predictable, the calculation is often straightforward: your monthly salary is multiplied by 12 to estimate your annual income.

But Försäkringskassan can also include other types of income, as long as they are recurring and expected to continue for at least six months. This can include things like:

• overtime pay
• shift-related compensation (for example evening or weekend pay)
• commissions
• other regular supplements connected to your work

So the key is not just whether you earned it once, but whether it is part of your normal income pattern.

There are also clear limits for what can count as SGI:

• The ceiling
  There is a maximum SGI level, linked to the price base amount, called prisbasbelopp. For sickness benefit, the ceiling is 10 times the prisbasbelopp.
• The minimum
  To qualify for SGI-based compensation at all, you generally need to earn at least 24% of the prisbasbelopp per year.

These thresholds matter because they decide whether you can receive sickness benefit based on SGI, and they also set the upper limit for how high the benefit can be.

Why “80%” is not exactly 80%

Many people say that Swedish sickness benefit is 80% of your income, and that is true in a simplified way. But the real calculation is slightly lower because Försäkringskassan applies a conversion factor of 0.97 (set by the Swedish Parliament). In practice, this means your benefit is calculated as: 80% of 97% of your SGI.

So even if you hear “80%,” your real compensation is usually a bit under that, due to this 0.97 factor.

Daily payment and how it is calculated

The daily sickness benefit is typically calculated like this:

Daily benefit = (SGI × 0.97 × 0.80) ÷ 365

An important detail in Sweden is that this daily amount is paid for all seven days of the week, including weekends and public holidays. So the system uses a full-week model, not only working days, when it calculates and pays out sickness benefit.

Price Base Amounts for 2025 and 2026

The price base amount, called prisbasbelopp, is updated every year to reflect inflation and general economic changes. Because the ceiling for SGI and the maximum daily sickness benefit are directly linked to this amount, the highest possible compensation levels are adjusted each year as well.

As shown in the official figures, the increase for 2026 is relatively modest, around 0.7 percent. This smaller adjustment, compared to previous years, reflects a more stable inflation level in the Swedish economy.

The Rehabilitation Chain: rehabiliteringskedjan

Sweden uses a structured timeline to assess a person’s work capacity during longer periods of sickness. This system is called the Rehabilitation Chain, in Swedish rehabiliteringskedjan. It includes specific milestones where the requirements for receiving sickness benefit become gradually stricter.

Milestone 1: Days 1 to 90

During the first 90 days of a sick leave period, Försäkringskassan evaluates whether the employee can do their regular job tasks. If the employee cannot perform their usual duties, the agency also checks whether the employer can temporarily offer other tasks within the same workplace.

Milestone 2: Days 91 to 180

From day 91, the assessment becomes broader. The agency looks at whether the employee can perform any type of work for the same employer. For example, if a construction worker cannot do physical work due to a back injury, Försäkringskassan will ask the employer whether there are administrative or more sedentary duties within the company that the employee could do instead.

Milestone 3: Days 181 to 365

The most important change happens on day 181. At this point, Försäkringskassan assesses the employee’s work capacity against the “regular labour market,” in Swedish hela arbetsmarknaden. This means the agency looks beyond the person’s current employer. If the employee is considered physically or mentally able to do any job that exists in the Swedish labour market, even in a different field or at a lower skill level, they may lose their right to sickness benefit.

There are exceptions to this stricter assessment:

Serious illness: If the employee has a life-threatening or exceptionally severe condition (for example certain cancers or advanced neurological diseases), the assessment can continue to focus only on the person’s regular job.

High probability of return: If it is very likely that the employee will be able to return to their original job before day 366, the assessment against the general labour market can be skipped.

Milestone 4: After Day 365

After one year (364 days), the sickness benefit level usually becomes lower. The “continuation level,” called fortsättningsnivå, is roughly 75% of the SGI (and it is still multiplied by the 0.97 factor), instead of the initial 80% level. People with very serious illnesses can apply to keep the 80% level.

Employer obligations and the return-to-work plan

In Sweden, employers have a proactive legal responsibility to support rehabilitation. This means they cannot simply wait for an employee to recover. They must actively investigate what measures can help the employee recover and return to work faster.

Systematic monitoring of sick leave

Managers are encouraged to follow sick leave patterns over time. If an employee has six or more cases of short-term sick leave within a 12-month period, the employer should start a “preventative rehabilitation meeting.” The purpose is to check whether workplace factors might be contributing to the repeated absences, and to create an action plan that can reduce the risk of a longer sick leave later.

Creating the return-to-work plan

If an employee is expected to be sick for 60 days or more, the employer is legally required to create a written “Plan for Return to Work,” called plan för återgång i arbete. This plan must be completed no later than day 30 of the sickness period.

The plan should include:

• A description of the employee’s work tasks and their current work capacity
• Concrete actions the employer will take, such as workplace adjustments, changed working hours, or assistive equipment
• A timeline for when actions will be introduced and how follow-ups will happen

An employer does not need to create a plan if the employee’s condition makes a return to work completely impossible, but this must be documented. If the employer fails to produce a solid plan, Försäkringskassan can report the employer to the Swedish Work Environment Authority, Arbetsmiljöverket.

Workplace-focused rehabilitation support

To support employers in meeting these requirements, Försäkringskassan can offer financial grants. An employer may receive up to SEK 10,000 per employee per year to buy expert support (for example occupational health services) to investigate and plan a return to work. The grant covers 50% of the cost of these services.

Rules for self-employed individuals and business owners

If you run a business in Sweden, your sick leave rights depend strongly on your legal business structure. The system works differently for owners of limited companies and for sole traders.

Owners of Limited Companies: aktiebolag

If you own a limited company, called aktiebolag (AB), you are technically considered an employee of your own company. This means you follow the same sick leave rules as other employees.

This includes:

• Your company pays sjuklön during the first 14 days
• A karensavdrag is deducted from your salary
• You must report yourself sick to your company on day 1 and to Försäkringskassan after day 14

Your sickness benefit is based on the salary you have actually paid yourself and reported to the Swedish Tax Agency. This is very important. If you choose to take a low salary in order to keep more money inside the company, your SGI will also be low, and that means your sickness benefit will be lower.

Sole traders: enskild firma

If you run a sole proprietorship, called enskild firma, you are not considered an employee. You do not receive sick pay from your business. Instead, you apply directly to Försäkringskassan for sickness benefit from the first day of illness.

Sole traders can also choose their own waiting period, called karensdagar. This choice affects how much you pay in social security contributions. The more waiting days you choose, the lower your health insurance contribution will be. If you do not actively choose a waiting period, the default option is 7 waiting days.

For sole traders, SGI is calculated based on the expected net profit (surplus) of the business, not on a salary. This means Försäkringskassan looks at what you are expected to earn from your business activities when determining your SGI and future sickness benefit.

If your business is new, meaning it has existed for less than 36 months, there is a special protection period called uppbyggnadsskede (build-up period). During this time, your SGI can be based on what a comparable employee would normally earn in a similar role, instead of your actual business profit.

High-risk protection: högriskskydd

Some people have a higher risk of being ill because of a chronic condition or a disability. In Sweden, there are two types of high-risk protection, called högriskskydd. The goal is to make sure these individuals are not unfairly punished financially, and also to make it easier for employers to hire them.

General high-risk protection

This protection happens automatically. An employee can only have a karensavdrag applied a maximum of 10 times during a rolling 12-month period. From the 11th time the person becomes sick within that period, the employer cannot make a new deduction. Instead, sick pay must be paid at 80% from day 1.

Special high-risk protection: särskilt högriskskydd

Special high-risk protection is for people who have a medically documented illness or disability that leads to frequent sick leave (at least 10 times per year) or long sickness periods (at least 28 days at a time).

To get this protection, you must apply through Försäkringskassan and include a doctor’s statement. If the application is approved:

• The employer does not make a karensavdrag when you are sick, so you receive pay from day 1
• The employer can apply to Försäkringskassan to be fully reimbursed for all sick pay and employer social security costs for that employee

This setup removes the financial burden from the employer and gives the employee a more stable income.

Supplemental benefits: collective agreements (kollektivavtal)

A big part of the Swedish labour market is the collective agreement, called kollektivavtal. These agreements are made between unions and employers, and they often provide much better sick leave benefits than the basic rules in the law. Around 90% of workers in Sweden are covered by a collective agreement.

The 10% top-up

Many collective agreements include a “sickness benefit supplement,” called sjukpenningtillägg. While Försäkringskassan pays close to 80% of income up to the ceiling, the collective agreement often requires the employer to add an extra 10%. This means the employee can receive 90% of their actual salary during the first 90 days of illness.

Protection for higher salaries

Because there is a statutory ceiling (based on 10 times the prisbasbelopp), people with higher salaries would lose a large part of their income if they depended only on Försäkringskassan. Collective agreements often solve this by requiring the employer, or an additional insurance solution (such as ITP or AGS), to cover a significant share of the salary above the state ceiling. In many cases, this extra coverage is around 75–90% of the part of the salary that exceeds the ceiling.

For employees, it is very important to check your specific kollektivavtal to understand whether you are entitled to these additional benefits. The details can differ depending on the agreement and sector.

For employers, knowing exactly what the collective agreement requires is essential for correct payroll handling and cost planning during sick leave periods.

Sick leave in special circumstances

The Swedish system also takes into account that illness can happen in different life situations, and sometimes it overlaps with other types of leave or support.

Illness during vacation

If you become ill while you are on annual leave, you have the right to stop counting those days as vacation and register them as sick days instead. You must report the illness to your employer on the first day. This makes it possible to save your vacation days for a time when you are actually healthy and can use the holiday for real rest.

Occupational injury: arbetsskada

If an illness or injury is caused by work, it can be classified as an occupational injury, called arbetsskada. This can also include accidents that happen during commuting. In the beginning, the normal rules for sick pay and sickness benefit usually apply, but the person may also have the right to extra compensation through work injury insurance, such as TFA. This additional compensation can cover things like medical costs, loss of income, or permanent impairment.

Students and job seekers

Students: If you receive grants or loans from CSN, you can keep that support if you become ill and report it to Försäkringskassan. This helps you avoid falling into debt if you cannot study due to illness.

Job seekers: If you are unemployed, you can receive sickness benefit if you are too ill to look for work. The benefit level is limited by the maximum unemployment benefit level (a-kassa). Since October 2025, the unemployment system has been moving to an income-based model, which further aligns how these calculations are handled.

Care of a sick child: VAB

This is technically separate from your own sick leave, but it often comes up in everyday life. The system called vård av barn (VAB) allows parents to stay home with compensation, called tillfällig föräldrapenning, when a child is ill. This benefit is also based on SGI, but it has a lower ceiling than personal sickness benefit: 7.5 times the prisbasbelopp.

The role of other agencies: Skatteverket and Arbetsförmedlingen

Försäkringskassan does not operate on its own. It depends a lot on information from the Swedish Tax Agency, Skatteverket, especially to confirm income through the monthly employer declarations, AGI. This data is the main basis for calculating SGI and for making sure benefits are neither overpaid nor underpaid.

If an employee’s sickness benefit is denied because they are considered able to work on the general labour market, Försäkringskassan can coordinate with the Public Employment Service, Arbetsförmedlingen, to support the person in moving towards a new job. This can include a “career readjustment meeting,” where the agencies, the employer, and the employee meet to discuss what happens next and what steps should be taken.

Contemporary challenges: stress and mental health

One clear trend in Swedish sick leave is the strong increase in stress-related mental ill health, including exhaustion syndrome. In 2024, stress-related sick leave reached record-high levels, especially among women working in healthcare and education.

Today, stress-related illness accounts for around 21% of all sickness benefit costs. Because these conditions often lead to long absences, Försäkringskassan and employers are placing more attention on the psychosocial work environment. Research suggests these absences are often connected to organizational obstacles and lack of resources, not only individual health issues. For employers, this shows why the “Return-to-Work Plan” should not be treated only as a medical form, but also as a practical tool to improve how the workplace functions.

Summary of key data and procedural milestones

To sum up, the Swedish sick leave system is a highly structured framework. It combines strong financial support with a clear expectation of active rehabilitation and participation.

This way, you do not have to search through long articles again. You will have the key timelines, responsibilities, and checkpoints in one simple document, ready to use.

The big picture (and what to remember)

By following these rules and using the support that exists, like rehabilitation grants and high-risk protections, both employees and employers can handle sickness periods in a more predictable way, while still protecting the idea behind the Swedish welfare model.

And because base amounts increase slightly into 2026, the financial ceilings will also move. This helps the system keep its protection against inflation and makes sure the safety net stays strong and relevant for everyone who contributes to the Swedish labour market.
