The Danish Tax Year for Businesses: A Simple Guide

If you are running a business in Denmark, understanding the tax year is fundamental. The system is logical, but it has its own rhythm and vocabulary. It is different from what you might be used to. This guide explains the structure, the key dates you need to know, and how it all works for an international business owner.

First, the basics. The Danish tax system is managed by the Danish Tax Agency, known as SKAT. You will interact with them for everything related to your company's taxes, from VAT to corporate income tax. Let's break down how the year is structured.

The Structure of the Tax Year

For most companies, especially new ones, the tax year (or income year, indkomstår) aligns with the calendar year. It runs from 1 January to 31 December. This is the default and simplest option.

However, a Danish company (like an ApS or A/S) is not required to follow the calendar year. You can have a different financial year, for example, from 1 July to 30 June. This is called a forskudt indkomstår (displaced income year). This choice is often made to align with a parent company's financial reporting cycle or for industry-specific reasons. You must declare this when you register the company, and changing it later requires a formal process.

Personal vs. Corporate Tax Year

It is important to separate your personal tax year from your company's. As an individual, your tax year is always the calendar year. There is no flexibility here. Your personal tax return, the årsopgørelse, deals with your salary, personal deductions, and any income you have outside your company.

Your company's tax year is about its own profits and losses. The company files its own tax return, the selvangivelse (also sometimes called the oplysningsskema). The two are connected—the salary you pay yourself from the company is a business expense for the company and personal income for you—but their tax reporting calendars can be different.

Key Taxes and Deadlines

There are several types of tax and reporting deadlines to track. Missing them results in fines, so it is good practice to get them in your calendar from day one.

Moms (VAT)

Moms is the Danish term for Value Added Tax (VAT). Most businesses in Denmark must register for and charge moms. The reporting frequency depends on your company's annual turnover.

For quarterly reporting, the deadlines are on the first day of the third month after the quarter ends. For example, for the first quarter (January-March), the deadline is 1 June. For monthly reporters, the deadline is the 25th of the following month.

A-skat and AM-bidrag (Employee Taxes)

If your company has employees, including yourself if you draw a salary, you must withhold and pay employee taxes. This consists of A-skat (income tax) and AM-bidrag (labour market contribution).

These are reported and paid monthly. The deadline is the 10th of the following month. For a small company, this is often handled by a payroll system, but the company owner is ultimately responsible for ensuring it is paid correctly and on time.

Corporate Tax (Selskabsskat)

This is the tax on your company's profits. The current rate is 22%. Unlike moms or employee taxes, corporate tax is paid in two instalments during the tax year, based on an estimate. This is the aconto skat system.

The two ordinary payment deadlines are 20 March and 20 November. These payments are based on your expected profit for the year. After the year ends, you file the final tax return, and the final tax is calculated.

Estimated vs. Final Tax: Forskudsopgørelse and Årsopgørelse

This is a core concept in the Danish system. You pay tax based on a forecast, and then you correct it based on the actual result.

1. The Estimate (Forskudsopgørelse): When you start your company, SKAT asks you to estimate your expected profit for the coming year. This estimate forms the basis for the two corporate tax payments in March and November. If you expect a profit of DKK 200,000, your estimated tax will be 22% of that, or DKK 44,000. This amount is then split into the two payments.

1. The Final Statement (Årsopgørelse / Selvangivelse): After your financial year is over, you prepare your annual accounts. This shows your actual revenue, costs, and profit. You submit this information to SKAT in your corporate tax return (selvangivelse). The deadline for this is generally six months after your financial year ends. If your year follows the calendar, the deadline is 30 June.

If your actual profit was higher than the estimate, you will need to pay the remaining tax (restskat). If it was lower, you will receive a refund (overskydende skat).

The First Year of Operation

The first year can feel complicated because you are setting everything up. When you register your company (a process called stiftelse), you will be asked to provide your expected profit for the first year or two. This is your initial forskudsopgørelse.

It can be difficult to predict your profit. It is better to be realistic or slightly conservative. If you estimate too high, you will pay more tax during the year, which can affect your cash flow. If you estimate too low, you will have a larger tax bill to pay later. You can adjust your estimate during the year if you see that your business is performing differently than expected.

In your first year, you might not have a full 12-month financial period. For example, if you register your company on 1 July and follow the calendar year, your first financial "year" will only be six months long. The tax reporting is adjusted accordingly. Your first corporate tax return will cover this shorter period, and the deadline is still six months after the period ends.

Getting the first year right is important for building a healthy financial foundation. It sets the precedent for your reporting habits and your relationship with SKAT. While the system is automated, it is not something you can ignore. Stay organised, keep good records, and do not be afraid to ask for help.
