Tax lawyer
Tax lawyer for tax cases
Tax law is our core area, not a side discipline.
A case with the Danish Tax Agency is rarely just a question of figures. It is about evidence, deadlines, how your transactions are legally characterised, and how your explanation is understood by an authority that has already formed a view.
HAY LAW is a boutique law firm where tax law is the core area. We handle cases for individuals, majority shareholders, self-employed people and businesses through the entire process: from the first proposed assessment from the Danish Tax Agency, on to the Danish Tax Appeals Agency and the National Tax Tribunal and, where necessary, before the courts.
When should you involve a tax lawyer?
The timing of involving a tax lawyer can matter a great deal. The factual and legal framework of a case can start to take shape as early as a request for material or a proposed assessment.
You should get in touch when:
- You have received a request for material and are unsure what you should submit and what you are not obliged to submit.
- You have received a proposed assessment and the deadline for comments is running.
- The Danish Tax Agency wants to reopen income years more than three years back.
- Your case concerns bank deposits, private loans, disguised dividends, capital gains on property or a denied VAT deduction.
- Your case has been referred to the Danish Tax Agency's criminal cases unit, or you have been summoned to a liability meeting.
- You are considering an appeal but are unsure whether the Danish Tax Appeals Agency or the National Tax Tribunal is the right route.
The earlier a lawyer becomes involved, the greater the room for manoeuvre. A proposed assessment can be withdrawn. A final decision must be appealed.
The cases we handle
- Tax cases, discretionary assessments, bank deposits, private loans, disguised dividends, share gains, property gains, denied deductions, majority shareholder taxation, and questions of reopening and time limits.
- VAT and duty cases, denied VAT deductions, documentation requirements for subcontractors, chain fraud issues, duty increases.
- Criminal tax cases, cases involving intent or gross negligence under tax and VAT legislation, fine cases, liability meetings and prosecution before the courts.
- Litigation, review of tax assessments before the district and high courts.
How we work
We do not take on cases in large numbers. That is a deliberate choice. In tax cases, thoroughly prepared documentation and a precise legal framework can be decisive for the outcome.
We start by understanding the facts, not by writing. The first step is a review of the material the authority already holds and a clarification of what can actually be documented. That determines whether the case should be run on evidence, on the law or on formality, for example whether the conditions for extraordinary reopening are even met.
We set the strategy early. A case that is sharply defined at the first instance rarely gets worse later. Several of our results were achieved before the case reached an appeal body.
You speak to the lawyer handling your case. There is no layer in between.
You know what you are getting. We agree the terms of the engagement in advance, and we assess reimbursement of costs where the conditions may be met.
