- What starts the clock
- The date the scheme administrator first knew of the member's death, or if earlier the date they could first reasonably have been expected to know of it (not the date of death itself)
- How long
- Within two years of that date
- What is lost
- The defined benefits lump sum death benefit is taxable if the lump sum was not paid within the two year payment period shown above, and the amount of the lump sum that exceeds the deceased member's available allowance will be taxed as pension income at the recipient's marginal rate; for payments before 6 April 2016 the manual instead states that a lump sum not paid within the two year period is not a defined benefits lump sum death benefit but an unauthorised member payment and should be taxed as such.
HMRC's Pensions Tax Manual states that if the member was under 75 when they died and the lump sum is paid within two years of the date the scheme administrator first knew of the member's death, or if earlier the date they could first reasonably have been expected to know of it, the lump sum will be tax free unless the payment exceeds the deceased member's lump sum and death benefit allowance. The manual separately states that the defined benefits lump sum death benefit is taxable if the lump sum was not paid within that two year payment period.
What the source does not say
This page addresses the scheme administrator's payment deadline and its tax consequence; it does not state any separate deadline for a beneficiary to notify the scheme of the death, and does not say what counts as reasonably have been expected to know for any given case.
