Writes off sums (6)

I believe the answer is:

totals

I believe this is a double definition.

'writes off' is the first definition.
(as in writing off or totalling a car)

'sums' is the second definition.
(I know this)

(Other definitions for totals that I've seen before include "Aggregations or sums" , "Sums and aggregates" , "Kills" , "Adds up the entire amounts" .)

I've seen this clue in The Times.
