Working while on a pension accrues new pension until you turn 68. Regardless of your age, pension accrues at 1.5% of your annual income.
While on an old-age pension you may work without any income limits but in many other types of pensions there are various limits for how much you may earn. For further information on these limits see the pages describing the various pension types.
If you already receive an old-age pension or early old-age pension based on municipal work, you will receive the new pension accrued from your work while on the pension when you turn 68. You need to apply separately for this new pension, however.
If you receive an old-age pension based on private sector employment or e.g. state or other public sector employment and work for a local government employer while on the pension, you will receive the new pension that you have accrued when you stop working, however at the earliest at 63 years of age. You need to apply separately for this new pension also.
If you are on a disability pension or unemployment pension, you will receive the new pension accrued from your work while on pension when the disability or unemployment pension converts into an old-age pension. You need to apply separately for this new accrued pension.
