Why Tax Deductions Matter
A tax deduction reduces your taxable business income.
For example, if your business earns $100,000 and you claim $20,000 in deductible expenses, you’ll generally pay taxes on $80,000 rather than the full amount.
Proper recordkeeping is essential for maximizing legitimate business deductions while preparing accurate small business taxes.
