Example: How Much Tax Can You Save?
Let’s say your business earns $100,000 annually.
- Total expenses claimed = $20,000
- Taxable income = $80,000
If you missed $5,000 in deductions, you could overpay approximately $1,400–$1,500 in tax depending on your tax rate.
This is why tracking and claiming every eligible expense is critical.
