What if my federal AGI is wrong?

Confirm and correct the federal return first if needed; Maryland uses federal AGI as the starting point. Attach an explanation if federal changes affect your Maryland tax.

Can I e-sign Form 502?

Yes; e-signatures are generally accepted under ESIGN and state rules for tax filings when the vendor preserves an audit trail and the state accepts electronic returns.

How long should I keep supporting documents?

Retain tax returns and supporting records a minimum of three years; retain six years if there is a substantial understatement of income per federal guidance.

What happens if I file late?

Late filing can result in interest and penalties on unpaid tax; file promptly to minimize penalties and consider payment options to limit additional charges.

Do I need a notary for Form 502?

No standard notary requirement exists for the individual income return itself, though supporting affidavits or other documents may require notarization.

How do I correct a filed Form 502?

File an amended Maryland return per state instructions; attach corrected federal forms if federal changes prompted the amendment and maintain documentation supporting the change.

What the Maryland State Tax Form 502 Is and when it applies

Maryland State Tax Form 502 is the individual income tax return used by residents and part-year residents to report taxable income and calculate Maryland state tax liability. The form collects personal identification, filing status, exemptions, income adjustments, credits, and payment or refund information.

Reconcile federal and state figures

Always cross-check federal adjusted gross income and itemized/deduction figures against Maryland-specific adjustments; discrepancies often cause rejections or follow-ups.

Use e-file where possible

E-filing reduces transcription errors, speeds refund delivery, and provides an electronic receipt for proof of filing; verify acceptance criteria before submission.

Maintain supporting records

Keep W-2s, 1099s, receipts for credits, and schedules for the recommended retention period to support future inquiries or audits.

Validate signer identity

When using e-signatures, apply an authentication level appropriate to tax documents and preserve the audit trail showing signer attribution and intent.
