You may file this application online at onestop.md. Maryland requires all homeowners to submit a onetime application to establish eligibility for the Homestead Tax Credit.A new owner will automatically receive an exemption claim form in the mail and there is no cost to file. To claim the exemption, the homeowner must make a one-time filing with the county assessor where the property is located. Additional credits for seniors 65 and older, and the disabled. The application, for the Homestead Tax Credit (HTC), is easy and takes less than 5 minutes to complete. Use the rules for filing separate returns in Instruction 8 of the Maryland resident tax booklet. Time is running out for Maryland homeowners to save some money on their taxes. I should now go online or complete the one time application immediately. Basically asking for the same thing I applied months ago online.
