Half a million people in Denmark have already viewed their tax assessment notices

Thousands of Danes Access Tax Assessment Notices Early as System Opens Ahead of Official Date

The annual tax assessment season in Denmark has once again begun with heavy online traffic, long digital queues, and widespread public interest, as hundreds of thousands of Danish citizens logged in to check their tax assessment notices earlier than the official opening date. The early access has become something of a yearly tradition, with taxpayers expecting that the tax system will become available before the announced opening day.

This year was no different. When access to the tax assessment system became available earlier than expected, more than 500,000 Danes logged in during the evening and late-night hours to find out whether they would receive a tax refund or have to pay additional tax. The high number of users logging in overnight demonstrates how important the annual tax assessment notice is for Danish citizens.

Early Access Has Become Expected

Over the past several years, early access to tax assessment notices has become almost predictable. Although the Danish Tax Agency officially announces a specific date for opening access to tax returns, the system often becomes available earlier. As a result, many Danish taxpayers now attempt to log in early in the evening before the official opening date to see if they can access their tax information ahead of time.

This year, when the tax website opened earlier than expected, thousands of people immediately logged in to check their tax results. Many citizens stayed awake late into the night to access the system as soon as possible. For many households, the tax assessment notice is an important financial document that determines whether they will receive money back or need to pay additional taxes.

Heavy Traffic Overnight

According to the Danish Tax Agency, the system handled a large number of users throughout the night. More than half a million Danes logged in to the tax website during the evening and late-night hours after access opened early.

Deputy Director General Ulrick Junge stated that the system ran very smoothly during the night despite the high number of users accessing the website at the same time. However, some technical problems appeared the following morning due to issues with the digital login system MitID.

MitID Login Problems in the Morning

While the tax system itself functioned well overnight, users experienced difficulties logging in during the morning because of problems with MitID, Denmark’s national digital identification system. MitID is required for logging into government services, including the tax system, banking services, and official digital communication with public authorities.

Many users reported that they were unable to log in to check their tax assessment notices due to the MitID issues. The Danish Tax Agency confirmed that the problem was related to the login system rather than the tax system itself.

Authorities worked to resolve the issue quickly, and by 9:00 in the morning the MitID problems had been fixed. After that, taxpayers were once again able to access their tax assessment notices without difficulty.

Most Taxpayers Expected to Receive Refunds

The Danish Tax Agency has predicted that the majority of Danish taxpayers will receive money back this year. According to estimates, approximately four out of five Danes will receive a tax refund, which is commonly referred to as receiving a “green number.”

A green number means that the taxpayer has paid more tax during the year than required and will therefore receive a refund. A red number, on the other hand, means that the taxpayer has paid too little tax during the year and must pay the remaining amount to the tax authorities.

The distribution between green and red numbers is usually similar each year in Denmark. Many taxpayers prefer to slightly overpay taxes during the year to avoid receiving a large tax bill later, which results in a higher number of refunds.

Deadline for Corrections

Even after receiving the tax assessment notice, taxpayers still have time to review and correct their tax information if necessary. The deadline for making corrections to the tax assessment notice for the 2025 tax year is May 20.

If a taxpayer finds that some information is incorrect or that deductions are missing, they can update their tax information before the deadline. Making corrections can significantly change the final tax result, sometimes resulting in a larger refund or reducing the amount of tax owed.

Refund Payments Begin in April

For taxpayers who are entitled to a refund, the Danish Tax Agency has announced that excess tax payments will begin to be paid out starting from April 24. Many taxpayers therefore expect to receive their tax refunds shortly after reviewing their tax assessment notices.

Tax refunds are often used by households for savings, travel, home improvements, or paying off loans and bills. Because of this, the tax assessment season is an important financial event for many Danish families.

Long Queues Expected on the Tax Website

The Danish Tax Agency expects heavy traffic on the tax website throughout the weekend, as many thousands of taxpayers will log in to check their tax results. Long virtual queues are common during the first few days after tax assessment notices become available.

Many citizens log in as soon as possible because they are eager to find out whether they will receive money back. The excitement surrounding tax refunds contributes to the large number of people accessing the system immediately after it opens.

Importance of Checking Tax Information Carefully

Authorities are advising taxpayers not only to check whether they receive a refund or must pay additional tax, but also to carefully review the information used to calculate the tax result.

Taxpayers should check:

• Income information

• Interest expenses

• Commuting deductions

• Service deductions

• Craftsman deductions

• Other work-related expenses

If any of this information is incorrect or missing, the tax assessment notice can be changed before the correction deadline.

Craftsman Deduction Reintroduced

One important deduction that taxpayers should check this year is the craftsman deduction, which was reintroduced in 2025. This deduction allows taxpayers to receive tax benefits for certain home repair and renovation work carried out in the previous year.

If a homeowner had repairs or renovation work completed last year, they may be eligible for this deduction. However, the expenses must be entered correctly into the tax system in order to receive the tax benefit.

The reintroduction of this deduction means that some taxpayers may be eligible for additional refunds if they remember to include the expenses.

Mileage Deduction Often Missing

The Danish Tax Agency has also noted that many taxpayers forget to enter their mileage deduction, which applies to people who commute to work over a certain distance. This deduction can significantly affect the final tax result.

If a taxpayer forgets to enter their commuting distance, they may appear to owe tax even though they should actually receive a refund. In some cases, the tax assessment notice can change by several thousand Danish kroner if the mileage deduction is added.

Because of this, the tax agency strongly recommends that taxpayers check their commuting deductions carefully.

Guidance Available Online

The Danish Tax Agency provides guidance on its website to help taxpayers enter deductions correctly. The website includes instructions, examples, and calculators that help taxpayers understand how to calculate their deductions and tax obligations.

Authorities also recommend that taxpayers review their preliminary income assessment for the current year to ensure that their tax payments are calculated correctly going forward. Adjusting the preliminary income assessment can prevent taxpayers from paying too much or too little tax in the future.

Official Opening Still Scheduled for Monday

Although many taxpayers were able to access their tax assessment notices early, the Danish Tax Agency has confirmed that the official opening date for checking tax returns is still Monday. Early access is not officially announced, but it has become common for the system to open earlier than expected.

Many Danish citizens now anticipate early access and attempt to log in before the official opening date each year.

A Major Financial Event for Danish Citizens

The release of the annual tax assessment notice is one of the most significant financial events of the year for Danish taxpayers. The document summarizes income, taxes paid, deductions, and the final tax result for the previous year.

It determines whether taxpayers:

• Receive a refund

• Need to pay additional tax

• Need to correct tax information

• Need to update their preliminary income assessment

Because the tax assessment can affect household finances significantly, many people are eager to check their results as soon as possible.

Conclusion

The early opening of Denmark’s tax assessment system once again attracted hundreds of thousands of taxpayers eager to check their tax results. Despite temporary technical issues with the MitID login system, access was restored quickly, and taxpayers were able to view their tax assessment notices.

Most Danish taxpayers are expected to receive tax refunds this year, with approximately four out of five citizens receiving money back. However, authorities emphasize the importance of reviewing tax information carefully and ensuring that all deductions are included correctly before the correction deadline on May 20.

With heavy traffic expected on the tax website and refunds scheduled to begin from April 24, the annual tax assessment season is now fully underway, marking one of the busiest and most anticipated financial periods of the year in Denmark.
