Common Mistakes in Completing Form 1040

Choosing the wrong filing status such as Single when Married or Head of Household when not eligible can lead to errors in tax calculations.

Forgetting to include social security numbers for yourself, your spouse, or dependents can delay processing and cause inaccuracies.

Failing to report all sources of income like wages, dividends, or IRA distributions can result in underreporting and potential penalties.

Claiming deductions incorrectly, such as not choosing between standard deduction and itemized deductions, can impact the final tax liability.

Forgetting to sign the tax return or spouse's signature on a joint return can invalidate the submission and require resubmission.
