Calculator Assumptions

The calculator makes the following assumptions:

  • 1. Main residence is left to direct descendants so the residence nil rate band (RNRB) has been applied. However, the    available RNRB has been reduced by £1 for every £2 by which the deceased’s net estate exceeds the taper threshold.
  • 2. Calculations for spouses or civil partners assume that all assets are either left to survivor on first death, or are owned by the couple as joint tenants, so form part of survivor’s estate on second death.
  • 3. No account is taken of any additional nil rate bands that may be available (e.g. as a result of being previously widowed).
  • 4. No account is taken of reduced rates of inheritance tax (e.g. where some or all of estate may be left to charities, for national purposes etc).
  • 5. Any lifetime gifts from the previous seven years can be set against an unused nil rate band.
  • 6. Assets deemed to be trading businesses will qualify for Business Relief and Assets deemed to be non-trading businesses will not qualify for Business Relief.
  • 7. APR/BPR Qualifying assets are assumed to be passed between spouses on first death.
  • 8. Calculations for assume all individuals are long-term UK resident.
