Hobbyvirksomhed or Enkeltmandsvirksomhed: When a Danish Influencer Must Register a Real Business

There's no fixed kroner threshold for when an influencer's income from brand deals stops being a hobby and becomes a real, registration-required business in Denmark. Skattestyrelsen decides it through an overall assessment of two criteria — profitability (rentabilitet) and intensity (intensitet) — and the consequences aren't just formal: a hobby business (hobbyvirksomhed) never has to register and never pays the labour-market contribution, but it also can never deduct a loss against other income.

This article is Make Influence's own summary of publicly available guidance, not tax advice. If your own situation is unclear, get it confirmed by an accountant or directly with Skattestyrelsen.

What actually decides hobby vs. business?

Per Skattestyrelsen's own legal guide (info.skat.dk, section C.C.1.3.1), whether an activity counts as erhvervsmæssig virksomhed (commercial business) or ikke-erhvervsmæssig virksomhed (hobby business) is decided through an overall, concrete assessment built on two main criteria:

• The profitability criterion (rentabilitetskriteriet). The activity must be organised with a realistic prospect of generating a profit on its primary operation, a reasonable return on invested capital, and a reasonable wage for the work put into it. A loss during a start-up or cyclical period doesn't by itself rule out commercial status, provided there's a genuine prospect of eventual profitability.
• The intensity criterion (intensitetskriteriet). The activity must meet an objective minimum scope and turnover — personal circumstances such as illness don't exempt an activity from this requirement.

Neither criterion decides it alone. Skattestyrelsen also weighs whether the activity is organised in a professional, businesslike way, whether the owner has the relevant qualifications, whether the setup is customary for the type of activity, whether the assets involved are kept out of private use, and whether the activity could, in principle, be sold to a third party. There's no single number an influencer can look up and compare their turnover against — it's an overall judgment of whether the activity genuinely resembles a systematic income source with a realistic prospect of profit, or is, in substance, an interest that happens to also generate some income.

In practice, for an influencer: a couple of one-off gifts or a single paid post, with no plan to repeat it, looks like a hobby. Regular, invoiced collaborations with several brands, where you actively seek out the work and have a realistic expectation of profit, looks like commercial business activity — see employee or self-employed? how Denmark classifies an influencer's income for the full three-way test this article builds on: the "self-employed business" category in that article, together with the profitability and intensity criteria here, is what decides whether you're over the hobby threshold.

What changes tax-wise between hobby and business?

The difference isn't only about registration — it changes how the income is taxed:

Per Skattestyrelsen's own legal guide (info.skat.dk, section C.C.1.1.2), the sentence that settles the loss question is: "Underskud fra hobbyvirksomheden kan ikke trækkes fra i årets anden indkomst" ("A loss from the hobby business cannot be deducted from the year's other income") — because a hobby loss is treated in law as an expression of private consumption, not a genuine business loss. It's the single rule that most often surprises influencers, and usually only once they've already had a loss-making year.

The VAT (moms) assessment is a completely separate question from this income-tax hobby/business line — it's decided under momsloven's own rules, not the profitability and intensity criteria above. The DKK 50,000 VAT registration threshold over 12 months is already covered in affiliate influencer marketing in Denmark — it applies regardless of whether you're classified as a hobby or a business for tax purposes, so a genuinely hobby-classified activity that grows large enough in turnover can, in theory, still raise a separate VAT question of its own. If that's your situation, it's a question for an accountant, not something this article can settle in general terms.

How do you actually register a business, once you're over the line?

Once the assessment points to commercial business activity, registering itself is simple: it's free, done on virk.dk, and you're issued a CVR number. There are two typical starting points for an influencer with moderate turnover:

This comparison draws on several independent Danish accounting and advisory sources (Erhvervsstyrelsen's own page on personally-owned businesses could not be fetched directly during research for this article — the same limitation noted while researching ApS or enkeltmandsvirksomhed). A PMV is, in practice, the administratively lighter option that fits an influencer with low but steady turnover under DKK 50,000, while a sole proprietorship is the starting point as soon as you either expect to grow past that ceiling or want the option to register for VAT voluntarily. The separate choice between a sole proprietorship and an ApS is covered in full in ApS or enkeltmandsvirksomhed: how a Danish influencer should structure their business.

Decision framework

• IF you've had one or two one-off collaborations with no realistic plan to repeat them THEN that looks like a hobby business — no registration needed, but no loss deduction either.
• IF you regularly invoice several brands, actively seek out the work yourself, and have a realistic expectation of profit THEN the intensity and profitability criteria point toward commercial business activity — register.
• IF you expect to invest in equipment (camera, lighting, software) before income really picks up THEN it's worth registering as a business early, because a hobby business can never deduct that start-up loss.
• IF your turnover is low and steady, and you don't plan to hire anyone THEN a PMV is the administratively lightest registration option.
• IF you're unsure because the picture is mixed THEN it's the overall assessment, not a single number, that decides it — get it confirmed by an accountant if there's real money at stake.

Worked example (hypothetical)

The figures below are made up for illustration only — not a real customer case.

Year 1 — a profit: An influencer earns DKK 10,000 from three small brand collaborations over the year and has DKK 2,000 in documented expenses directly tied to the work (props, an editing subscription). The net result is DKK 8,000 either way, but the tax treatment differs:

• As a hobby business: the DKK 8,000 is taxed as other personal income — no AM-bidrag is owed.
• As a commercial business: the DKK 8,000 profit first attracts 8% AM-bidrag = DKK 640, and the remaining DKK 7,360 is taxed as personal income.

Year 2 — a loss: The following year, the same influencer invests DKK 12,000 in new camera and lighting equipment, but only earns DKK 6,000 from brand collaborations that year — a DKK 6,000 loss.

• As a hobby business: the DKK 6,000 loss can't be deducted from other income that year (e.g. salary from a day job), and can't be carried forward to offset next year's hobby income either.
• As a commercial business: the loss can generally offset other taxable income for the year, or be carried forward, under the ordinary rules for commercial losses.

The example shows exactly why the timing of registration can have a real cost: the equipment investment in year 2 is identical either way — but only the commercial business can actually use the resulting loss.

Common mistakes

• Assuming there's a fixed kroner threshold. There isn't — it's always an overall assessment of profitability and intensity.
• Waiting to register until Skattestyrelsen raises the question. The earlier it's settled, the easier the bookkeeping, and the lower the risk of a retroactive correction.
• Assuming a start-up loss can be deducted as a hobby business. It never can — not that year, and not in any later year.
• Confusing the income-tax hobby assessment with the VAT assessment. The two are separate tests under separate rules.
• Registering a PMV and later being surprised by the DKK 50,000 turnover ceiling. If growth is likely, a sole proprietorship is often the right starting point instead.

Make Influence's perspective

In our experience, the hobby-or-business question is rarely relevant to a creator who's just received their first product or made one paid post — it only becomes real once the collaborations start repeating. Make Influence doesn't require a specific registration form from the creators we work with, but we do recommend that a creator who starts invoicing regularly settles the registration question early — particularly around equipment investment, where any resulting loss is only useful if the activity is already registered as a business. This is our own operational experience, not a general recommendation or tax advice.

FAQ

Is there a specific kroner threshold where a hobby becomes a business?

No. Skattestyrelsen uses an overall assessment of the profitability and intensity criteria, not a fixed amount.

Do I have to pay tax on hobby income?

Yes — profit from a hobby business is taxed as other personal income, but without AM-bidrag, and only under the net-income principle (deductions for expenses directly tied to the income).

Can I deduct a loss if my hobby runs at a loss?

No. A loss from a hobby business can neither be deducted from the year's other income nor carried forward to later years — that's only available for commercial business activity.

Do I need a CVR number to invoice a brand?

Only if the activity is assessed as commercial business. A hobby business doesn't need a CVR number, but also can't use virksomhedsordningen or carry a loss forward.

Does the DKK 50,000 VAT threshold also apply to a hobby business?

The VAT assessment is separate from the income-tax hobby/business line. See affiliate influencer marketing in Denmark for how the VAT threshold works in practice — if you're unsure about your own situation, that's a question for an accountant.

Should I choose a PMV or a sole proprietorship when I first register?

It depends on whether your turnover realistically stays under the PMV's DKK 50,000/year ceiling, and whether you need to register for VAT voluntarily or hire anyone — either of those requires a sole proprietorship instead.

Do gifted products count toward the hobby-threshold assessment?

Yes — the market value of products you receive as payment for a service counts toward the overall assessment the same way cash payment does. See gifting vs. paid collaborations for how that distinction works.

What happens if I keep operating as a hobby business when I'm actually over the line?

Skattestyrelsen can reclassify the activity and retroactively assess tax and possibly VAT. The earlier you settle the classification yourself, the lower that risk.

Do I need to update my forskudsopgørelse when I move from hobby to business?

Yes — see the forskudsopgørelse for influencers for which field to correct once the income changes character.
