Standard Deduction
What is Standard Deduction?
The standard deduction is a fixed dollar amount set by the IRS that reduces your adjusted gross income (AGI) to determine your taxable income. It's a simplified alternative to itemizing deductions and is available to all taxpayers who don't itemize. The amount varies based on filing status, age, and whether you're blind, and is adjusted annually for inflation.
Why it matters
The standard deduction directly reduces your taxable income, potentially lowering your tax bill and tax bracket. Choosing between the standard deduction and itemizing can save you thousands in taxes. It's especially beneficial for taxpayers with few deductible expenses, simplifying tax preparation while providing automatic tax relief.
How it works
The IRS sets standard deduction amounts each year based on filing status: single filers, married filing jointly, married filing separately, head of household, and qualifying widow(er). Additional amounts are added for taxpayers aged 65 or older and those who are blind. The deduction is subtracted from AGI to calculate taxable income, which then determines your tax liability.
Examples
- A single filer under 65 with $75,000 AGI takes the $14,600 standard deduction, resulting in $60,400 taxable income for 2024.
- A married couple filing jointly with $120,000 AGI claims $29,200 standard deduction, leaving $90,800 taxable income.
- A 67-year-old single filer adds $1,550 to their standard deduction, increasing it from $14,600 to $16,150.
Common mistakes
- Not claiming the standard deduction when it's larger than itemized deductions
- Forgetting additional amounts for age or blindness
- Double-dipping by claiming both standard and itemized deductions
- Not comparing standard vs. itemized amounts annually
- Misunderstanding that some taxpayers cannot use the standard deduction
