Here's how you can tell which deduction you took on last year's federal tax return:
- If the amount on Line 12a of last year's Form 1040 ends with a number other than 0, you itemized.
- If this amount ends with 0, it's likely you took the Standard Deduction.
- If this amount ends with 00 or 50, you probably took the Standard Deduction.
- If your return included Schedule A, you itemized.
