    Maryland State Growth Credit

    • The growth credit is granted for 10% of the amount by which the Maryland qualified R&D expenses paid or incurred by the taxpayer during the tax year exceed the Maryland base amount for the taxpayer.

    The Maryland base amount is the amount that is the ceiling for the amount of R&D Expenses that qualify for the basic credit and the floor for the amount of qualified R&D expenses that qualify for the growth credit.

    R&D Tax credits certified after Dec. 15, 2012, are refundable for “small businesses” to the extent that the tax credits exceed the income tax liability for that taxable year. A small business is defined as one having net book value assets totaling less than $5 million at the beginning or end of the taxable year.*

    How to Obtain the Credit

    By September 15 of the calendar year following the end of the tax year when the Maryland qualified R&D expenses were incurred, the taxpayer must submit an application to the Department of Business and Economic Development (effective October 1, 2015, Department of Economic Competitiveness and Commerce) for the credits. A prescribed form must be used and lists the information that the taxpayer must supply, including the North American Industrial Classification System (NAICS) code number for the business entity and amounts needed to compute the credit that the taxpayer is claiming. To claim the credit, the taxpayer must file an amended return for the tax year when the Maryland R&D expense was incurred and attach a copy of the Department’s certification of the approved amount and Form 500CR (Maryland Business Income Tax Credits) to the amended return.

    Refundable/Transferable Tax Credit- Yes*


    If the credit in any tax year exceeds the taxpayer’s tax liability for that year, the taxpayer may carry over the excess as a credit for succeeding taxable years until the earlier of:

    • the full amount of the excess is used; or
    • the expiration of the 7th taxable year after the taxable year in which the Maryland qualified R & D expense was incurred

    Flow-Through Entities

    In the case of a subchapter S corporation, partnership, limited liability company, or business trust, the amount of the credits computed for the pass-through entity shall be allocated among the owners as agreed to in writing by the owners. If there is no written agreement governing the allocation of this credit, the credit shall be allocated in the same proportion as other items are allocated for the taxable year.
