The ring was worth about 1 or 2 loaves of bread. It was garbage. Plus it wasn't a taxes guy, it was some corrupt guard who went around bullying people. The taxes guy was killed by some libretarian dark elf who thought that he didn't need to pay taxes. Hurr. Durr. I can't afford to pay 20 coins this year for road and guards to patrol the countryside fighting monsters. Spending 5 minutes gathering mushrooms and flowers to sell to the local alchemist is too hard. I'll go kill the taxman instead because nothing could go wrong with this plan.
