Frequently Asked Questions

What's the most important thing to check before filing?

Verify all dependents meet requirements (residency, support, age, income, SSN) and that you're using the correct filing status. Also, make sure you're claiming all eligible credits.

Do I need to keep all these documents?

Yes. Keep all tax documents for at least 3 years (statute of limitations for audits). Some documents (like records of major purchases) should be kept longer.

What if I'm missing some documents?

Try to obtain missing documents. If you cannot obtain them, provide what you have and explain what's missing. The IRS may accept alternative documentation.

Should I file my own return or use a professional?

It depends on your situation. Simple returns can be done yourself. Complex situations (divorce, self-employment, high income, etc.) may benefit from professional help.

What if I discover an error after filing?

File an amended return (Form 1040-X) to correct the error. It's better to fix it yourself than wait for the IRS to discover it.
