Do i send copy of MD federal tax return with my MD state filing?

No, you do not need to send a copy of your Maryland (MD) federal tax return with your MD state tax filing. However, you should keep a copy for your records, as you may need to reference it while completing your state return. It's important to ensure that the information on both returns is consistent. Always check the latest guidelines from the Maryland Comptroller’s office for any updates or specific requirements.
