Moonlighting is illegal. It means undeclared work, and thus you get paid for work without paying tax; and your employer fails to inform the Danish tax authorities, SKAT, that you have been paid wages.
If you are under the age of 16, you are, however, allowed to receive money for work in private homes without paying tax. Perhaps you are paid for walking your neighbour's dog, mowing the lawn or for babysitting.
If you work for a business, you must pay tax regardless of your age. There are, however, special rules for children working in their parents' business. Likewise, there are certain exceptions for state pensioners. Read more about moonlighting here.
What you fail to obtain when you moonlight
If you are moonlighting, you risk to be fined – or, at worst, a prison sentence.
You may think that moonlighting means good money, but the one who really derives profit from this is your employer.
When you get paid for moonlighting, you are not insured if you are injured.
You also miss out on:
- Holiday pay
- Insurance, if you meet with an occupational injury
- Payment for overtime work
- Help if, suddenly, you do not get your pay
- Sick pay
- Employer's pension contribution
- A recommendation when you leave the workplace
- Mileage allowance
- A bank's endorsement if you wish to buy on credit
