New ‘death tax’ will cost some estates up to £6k The Government is pushing ahead with plans to raise probate fees by up to 3,770%. The proposals will see estates worth £2m or more pay £6,000 in probate fees, up from £155 currently. However, the increase is a reduction on the original plans, which would have seen a bill of £20,000 for the largest estates. Estates with a value of between £1m and £1.6m will have to pay £4,000. The Government said the changes were necessary to fund the courts system and were a "fair and more progressive" way of paying. It estimated the move would raise £185m a year by 2022/23.
