Sivutyöt

Sivutyöt, or side jobs, refer to paid work performed in addition to a person’s primary job. They can include freelancing, contract work, seasonal or gig work, and are typically done outside regular working hours. In Finland, sivutyö is generally allowed, but it is subject to the terms of the primary employment contract, collective agreements, and relevant laws.

The legal framework emphasizes that the secondary job should not conflict with the main job or harm the employer’s interests. Many contracts require the employee to notify or obtain consent before taking a sivutyö, and some occupations or agreements may restrict total working time or impose non‑competition obligations. The Working Hours Act limits excessive total hours, and employers may have policies on conflicts of interest and trade secrets.

Taxation and social security: Income from sivutyö is taxable. If the work is performed as an independent entrepreneur, the person may need to register as a sole proprietor, charge VAT if applicable, and keep accounting records. If the income is paid through the main employer or as a regular employment, withholding tax applies similarly to other employment income. Individuals should consider how additional earnings affect tax prepayments and potential deductions or credits.

Practical considerations: Before starting a sivutyö, review the primary contract, discuss with the employer, and ensure it does not create conflicts or fatigue. Maintain clear records, comply with applicable licensing or safety requirements, and choose an appropriate business model for invoicing and taxation.
