9 Common Tax Compliance Mistakes That Lead to Fines & Penalties
There are some frequent mistakes that businesses or individuals make when delivering their tax obligations that can trigger legal or financial repercussions from the tax authorities. These errors often result in penalties, fines, audits, and can materially impact the financial health and image of a taxpayer or company.
Tax Compliance
Tax compliance involved the process of ensuring that a taxpayer, including individual or company meets all legal requirements arising from taxation. This includes:
- Registering with the relevant tax authorities
- Keeping proper financial records and documentation
- Timely and accurate filing of returns
- Paying the correct amount of tax due
Common Tax Mistakes
These are common errors often identified by the tax authorities among taxpayers due to ignorance of tax laws, lack of oversight, negligence, or deliberate non-compliance.
Fines & Penalties
These are monetary charges imposed by the tax authorities as punishment for non-compliance. They can be in form of:
- Fixed amount
- Percentage penalties (e.g., a percentage of the unpaid tax)
- Interest charges (at the prevailing CBN rate)
