All foreign corporations must register with Maryland to legally conduct business. In order to register as a Maryland foreign corporation, you'll have to file a Maryland Corporation Foreign Qualification Form with the Maryland State Department of Assessments and Taxation, Corporation Charter Division.
You must file your Maryland Amended Form 502X electronically to claim, or change information related to, business income tax credits from Form 500CR.
You can file electronically from your personal computer, using approved software and link to the provider's site to file online from your PC, or link directly to a provider site to prepare your return and file online.
To submit the Maryland Form 504, ensure all fields are accurately completed. You can file the form by mail to the Comptroller of Maryland, Revenue Administration Division, 110 Carroll Street, Annapolis, MD 21411-0001.
If you need to submit certain forms (or attachments) with your return, you are still able to e-file. However, you will need to complete and mail in Form 8453 U.S. Individual Income Tax Transmittal for an IRS e-file Return along with the forms or attachments.
File Forms 504 by the 15th day of the 4th month following the close of tax year or period. All business credits taken on the 502S and 504CR must be filed electronically. Maryland requires certifications and supporting documents be attached as a PDF.
Maryland follows the federal income tax treatment for fiduciaries of trusts and estates. Under the federal income tax rules, generally any income that is distributed by the fiduciary of the trust or estate during the tax year is not taxable to the trust or estate. Instead, that income is taxable to the beneficiary.
