For taxes, it's the arrangement (6)
I believe the answer is:
tithes
'for taxes' is the definition.
The definition and answer can be both related to property as well as being plural nouns.
Maybe they are linked in a way I don't understand?
'it's the arrangement' is the wordplay.
'arrangement' indicates anagramming the letters.
'its'+'the'='itsthe'
'itsthe' anagrammed gives 'TITHES'.
Can you help me to learn more?
(Other definitions for tithes that I've seen before include "Levies of one-tenth, to church perhaps" , "Tenth parts, levied by a church perhaps" , "Tenth portions of income given to church" , "Tenths of income once paid to church" , "Tenth parts, levied by some churches" .)
