A worker who suffers a permanent impairment as a result of a work injury may also be entitled to receive a lump sum payment for the impairment involved. A lump sum payment entitlement is calculated as a percentage, using formulas contained within the workers compensation legislation. Generally for physical injuries, the worker’s “Whole Person Impairment” (WPI) must be at least 5% and for psychological injuries at least 10% before an entitlement exists, further details relating to lump sum payments can be found here Workers Compensation: The Handbook WorkSafe Tasmania
