Businesses may file 2 month extension requests via the Department's website.
Extensions of the filing deadline of up to 2 months can be granted if the requests are made on or before April 15, 2009. The fastest, most reliable and convenient method is to visit our website. This option offers Department ID number look-up, extension verification, confirmation numbers and recall lists by confirmation number. Always print and keep a copy of the confirmation page. The Department will automatically accept it as evidence of a valid approved extension in case there is ever a problem. To request an extension, go to: www.dat.state.md.us and click on the extension link under "What's New". When you file for an extension via our website, do NOT also submit a paper extension request. Please file early to avoid possible delays due to the heavy usage of this system which occurs in the last week prior to April 15th.
· Extension requests should be requested through the Department's website at www.dat.state.md.us . Paper extensions require a $20 non-refundable processing fee and must be received or postmarked by March 16, 2009. · The manufacturing/R&D application deadline is September 1, 2009. A manufacturing exemption cannot be granted unless a timely application is filed. Once filed, no additional applications are required in subsequent years. · Entities requesting a revised assessment due to other missed exemptions (vehicles, software, charitable organizations, etc.) must file that request within three years of the April 15th date the return was due. · Do not prepay late filing penalties. · Personal property of home based sole proprietorships may be fully exempt if the total original cost of the property, including inventory and excluding licensed vehicles, is less than $10,000. An initial return must be filed to receive this exemption. · The home based business exemption can only be granted to businesses with a single individual as the owner. · If the business needs a trader's license, commercial inventory (line item ) must be reported. · File the pre-addressed return to ensure proper posting to your account. · The return must be signed by the owner or partner.
