Interest and penalties
Interest and penalties play an important role in tax administration by:
- deterring non-compliance by making it unprofitable to taxpayers
- promoting equity among taxpayers by ensuring that those who meet their obligations are not disadvantaged in comparison with those who do not
- compensating the government for being denied the use of funds that it is entitled to.
