Common Mistakes to Avoid

• Leaving the estimated tax liability blank – the IRS requires an estimate.
• Entering an incorrect Social Security Number.
• Forgetting to sign the form; an unsigned Form 4868 will be rejected.
• Submitting after the original filing deadline; the extension must be filed by the due date.
