What is the Standard Deduction?
The Standard Deduction is a fixed dollar amount that reduces your taxable income. You do not need to provide documentation of expenses to claim it, unlike itemized deductions. Most taxpayers claim the standard deduction due to its simplicity and beneficial amount.
IRC Code Reference for Standard Deduction
The Internal Revenue Code § 63(c) provides the legal basis for the standard deduction. It specifies deduction amounts and adjustments for age, blindness, and filing status.
2025 Standard Deduction Amounts
For the 2025 tax year, the standard deduction amounts (adjusted for inflation) are:
| Filing Status | Standard Deduction |
|---|---|
| Single | $14,600 |
| Married Filing Jointly | $29,200 |
| Head of Household | $21,900 |
| Married Filing Separately | $14,600 |
| Qualifying Surviving Spouse | $29,200 |
Add $1,950 if you are 65 or older or legally blind ($1,550 if Married Filing Jointly).
Who Can Claim the Standard Deduction?
You may claim the standard deduction if:
- You are not itemizing deductions
- You are not a nonresident alien (with rare exceptions under IRC § 873)
- You are not filing for a short period return due to a change in accounting period
- You are not filing Form 1040-NR
When Should You Itemize Instead?
Itemizing might be better if:
- You paid high medical expenses, mortgage interest, property taxes, or made large charitable contributions
- Your total itemized deductions exceed the standard deduction
- You had significant casualty or theft losses
Use Schedule A (Form 1040) to itemize.
Step-by-Step: How to Claim the Standard Deduction
Step 1: Choose Your Filing Status
Determine if you qualify as Single, Married Filing Jointly, Head of Household, etc.
Step 2: Check If You Qualify
Ensure you’re not required to file Form 1040-NR or a short-period return.
Step 3: Use IRS Form 1040
Report your standard deduction on Line 12 of Form 1040.
Step 4: Add Additional Deduction (if applicable)
Add $1,950 (or $1,550) for age 65+ or blindness on Line 12c of Form 1040.
Example: Calculating Taxable Income Using Standard Deduction
Scenario:
- Olivia, age 45, files as Single.
- Her AGI is $78,000.
- She has no significant deductions to itemize.
Calculation:
AGI = $78,000
Standard Deduction (Single) = $14,600
Taxable Income = $78,000 – $14,600 = $63,400
She’ll pay tax only on $63,400, not the full $78,000.
Key IRS Forms to Use
| Form | Purpose |
|---|---|
| Form 1040 | Main tax return form; Line 12 reports deduction |
| Schedule A | To itemize instead of claiming standard deduction |
| Form 1040-NR | Nonresident aliens—cannot claim standard deduction (with limited exceptions) |
Conclusion
The standard deduction simplifies tax filing and can significantly reduce your tax bill. For most taxpayers, it’s the most straightforward and beneficial choice. However, you should always compare it with itemizing—especially if you have mortgage interest, large medical bills, or charitable donations. A quick review with a CPA can save you thousands.
