Understanding Tax Deductions

Tax deductions are one of the most powerful tools for reducing your tax liability. Understanding what deductions are available and how to claim them properly can save you significant money on your tax bill.

What Are Tax Deductions?

Tax deductions reduce your taxable income, which in turn reduces the amount of tax you owe. There are two main types of deductions: standard deductions and itemized deductions.

Standard Deduction vs. Itemized Deductions

The standard deduction is a fixed amount that reduces your taxable income. For 2024, the standard deduction amounts are:

• Single: $14,600
• Married Filing Jointly: $29,200
• Married Filing Separately: $14,600
• Head of Household: $21,900

Itemized Deductions

Itemized deductions allow you to deduct specific expenses. You should itemize if your total itemized deductions exceed your standard deduction.
