Our clients include businesses of all sizes, from smaller companies to large groups.

How we help

Which companies can claim the R&D tax relief?

The R&D tax relief is a tax incentive for companies conducting qualifying research or development in Sweden. For the relief to be claimed, the work must meet the Swedish Tax Agency’s requirements, have a commercial purpose and be supported by accurate documentation. You are generally entitled to claim the R&D tax relief if you meet the following criteria:

01.

Employer social security contributions in Sweden

02.

Qualifying research or development

The work must meet the definition of research or development under the Swedish Social Contributions Act and go beyond routine improvements.

03.

Commercial purpose

The R&D work must be carried out for a commercial purpose. Projects carried out by public-sector organisations or funded by public funds are not covered.

04.

Clear documentation

You must be able to provide documentation supporting the projects, employees and working time covered by the claim.

05.

Sufficient working time within R&D

The employees concerned must spend at least half of their working time on R&D.
