What is a service- and carpenter deduction?

The service- and carpenter deduction is one of the most well-known deductions. In fact, more than a third of Danes have used it. In 2018 alone, almost 3 billion DKK was reported to Skat in carpenter deductions.

But according to Skat, we are still missing out on up to half of all eligible carpenter deductions. This is because it is not always quite straightforward to figure out when you are eligible for a deduction and how this should be reported to Skat.

In this article, we will cover:
  • What a service- and carpenter deduction is
  • When it applies
  • Other conditions you will need to be aware of
  • Whether you are eligible to receive any deductions

What is a service- and carpenter deduction?

A service- and carpenter deduction is a deduction you are eligible to receive if you are having certain renovations done to your home such as cleaning, gardening or replacing your windows. This can be renovations made to your home as well as your vacation home.

This is also referred to as a service deduction, which, when it comes down to it, is the same exact deduction. However, there are different types of services that are separated into "services" and "carpenter services" to which the deduction is different. We will cover exactly which is which down below.

What else do you need to be aware of?

A service- and carpenter deduction has several other conditions put in place to ensure that it is used correctly. The most important conditions are:

  • You must pay electronically, e.g. with dankort or MobilePay
  • You must pay before March 1st of the following year
  • The deduction only applies to maintenance and repairs
  • You are not eligible to receive the deduction if you have received a grant to work from a public support scheme or through your insurance
  • You must be able to provide an invoice, receipt or other relevant documentation
  • If the work is conducted by a business, the invoice must include VAT
  • If the work is done to a holiday home you rent out, you are not eligible to receive a deduction for services
  • If you live in a rental home or a housing co-op, you will need to check whether you are assigned the 'maintenance obligation' (this will typically be stated in your contract). Otherwise, you will not be eligible to receive the carpenter services deduction (although you can still receive deduction for the other category of services as explained above)
