    Effective for tax periods beginning after December 31, 2013 and subject to the $5 million overall cap and a limitation that the credit cannot exceed 50% of the qualified tax liability for the taxable year, a “small business” taxpayer may elect a credit equal to either:

    • 20% of the excess of the taxpayer’s total Delaware qualified research and development expenses for the taxable year over the taxpayer’s Delaware base amount, or
    • 100% of Delaware’s apportioned share of the taxpayer’s federal research and development tax credit calculated using the alternative incremental credit method under IRC § 41(c)(4)

    For purposes of the credit, a “small business” means any taxpayer with average annual gross receipts not more than $20 million as determined under IRC § 41(c)(1)(B).
