Maryland Form AT3-51: Essential Filing Information
Filing Form AT3-51 can be confusing, particularly when determining who must submit it. The official instructions specify that all sole proprietorships and general partnerships are required to file this return. However, LLCs taxed as partnerships often lead to misunderstandings about their filing obligations.
It’s important to clarify that the federal tax status of a business does not affect its filing requirements in Maryland. Specifically, an LLC must file Form 1 with the Maryland Department of Assessments and Taxation. This requirement remains regardless of whether the federal tax return is filed using Form 1065.
If your business is officially registered as a partnership in Maryland, then Form AT3-51 is necessary. Additionally, if your business owns rental properties containing tangible personal property, you will need to file Form AT3-53 as well.
When completing Form 1 for LLCs, you are required to include a balance sheet and a depreciation schedule, unless you do not claim any tangible property. Ensure that all forms include your Maryland Department ID number, which is essential for processing. You can obtain this number through the Maryland Department of Assessments and Taxation’s website here.
Typically, you must include a $300 filing fee with Form 1. Make sure to attach the check, made payable to the “Department of Assessments and Taxation,” and write your Department ID Number on the check to ensure proper credit.
