opplysningsperioden

Opplysningsperioden, or the information period, is a term used in Norwegian public administration to denote a defined time window during which individuals, businesses or institutions must provide certain information to a government authority. The period is determined by law, regulation, or administrative guidance and can vary depending on the context and the agency involved.

The concept is most commonly applied in areas such as taxation, social security, and administrative registration. In taxation, the opplysningsperioden covers the time frame for reporting income, deductions, and other financial information that authorities use to calculate tax or to pre-fill tax declarations. In other contexts, employers may be required to submit payroll and employee information, while banks and other institutions may report earnings or asset data. The exact duties and deadlines are set in relevant legislation and guidance and are communicated to the affected parties through official channels.

Practical considerations include the length of the period, the consequences of late or incomplete submissions, and the mechanisms for submitting information, often via digital portals such as Altinn. Individuals and organizations are typically able to review, correct, or supplement data within the established opplysningsperioden, and may face penalties or processing delays if information is not provided in time. The term emphasizes the administrative requirement to provide complete and accurate information within a specified timeframe.

Etymology: the word is formed from opplyse “to inform” and periode “period.” See also opplysningsplikt, Skatteetaten, Altinn.
