Tax Deductions Explained: What Reduces Your Taxable Income
Tax deductions reduce your taxable income, which can lower your tax liability. This guide explains how they work.
What Are Tax Deductions?
Tax deductions are expenses or allowances that reduce your taxable income. Lower taxable income means lower taxes.
Types of Deductions
Standard Deduction
A fixed amount that reduces taxable income without needing to itemize expenses. Available to all taxpayers.
Benefits:
- Simple to claim
- No documentation required
- Guaranteed tax reduction
Itemized Deductions
Specific expenses you can deduct if they exceed the standard deduction amount.
Common itemized deductions:
- Mortgage interest
- State and local taxes
- Charitable contributions
- Medical expenses (above threshold)
- Property taxes
How Deductions Work
Example:
- Gross Income: $75,000
- Standard Deduction: $14,600
- Taxable Income: $75,000 - $14,600 = $60,400
You pay taxes on $60,400, not $75,000.
