Claiming Business Income Tax Credits

For tax years beginning after December 31, 2012, you must file your tax return electronically in order to claim a business tax credit unless you submit a waiver from the electronic filing requirement. To request a waiver from filing the Form 500CR electronically, you must submit a completed Form 500CRW Waiver Request For Electronic Filing of Form 500CR and it must be attached to Form 500CR in the filing of your return.

Beginning with Tax Year 2015 certain individual taxpayers may elect to claim the Community Investment Tax Credit and/or the Endow Maryland Tax Credit on Maryland Form 502CR, and thus avoid the electronic filing requirement. Read instructions to Form 502CR to see if you qualify for this election.

Filing Deadline

Your income tax return is due July 15, 2021.

Business income tax return dates vary. See Filing Extensions and Deadlines for Corporations

New Tax Rates

Exemptions and Deductions

There have been no changes affecting personal exemptions on the Maryland returns.

Personal Exemption Amount - The exemption amount of $3,200 begins to be phased out if your federal adjusted gross income is more than $100,000 ($150,000 for joint taxpayers). The $3,200 exemption is phased out entirely when the income exceeds $150,000 ($200,000 for joint taxpayers). See Instruction 10 in the Resident tax booklet for the reduced amounts, or review the page, Determine Your Personal Income Tax Exemptions. The additional exemption of $1,000 remains the same for age and blindness.

Dependent Form 502B - will be required to be attached to Form 502, Form 505 and Form 515 to determine what exemptions you are entitled to claim. 

Standard Deduction - The tax year 2020 standard deduction is a maximum value of $2,300 for single taxpayers and to $4,650 for head of household, a surviving spouse, and taxpayers filing jointly.

Itemized Deduction Limitation - The State of Maryland follows the new federal tax law treatment to suspend the itemized deduction limitation threshold (Pease Limitation). This means that high-income taxpayers are not required to reduce their itemized deductions using the itemized deduction worksheet used in prior years.

Should I take the standard deduction or itemize? - The federal tax reform of 2017 significantly raised the federal standard deduction. Under current Maryland law, if you take the standard deduction the federal level, you cannot itemize at the Maryland level. You may take the federal standard deduction, while this may reduce your federal tax liability, it may result in an increase to your Maryland income tax liability. The Comptroller's Office encourages you to run your income tax returns under both deduction methods, and to compare the results of taking the standard deduction versus itemizing your deductions, to see which method causes the lowest overall tax liability.

Limitation on deduction for state and local tax - Federal tax reform limited the amount you can deduct for state and local taxes. You cannot claim more than $10,000 ($5,000 for married filing separately) for state and local taxes you paid. The new federal limitation impacts your Maryland return because you must addback the amount of state income taxes you claimed as federal itemized deductions. The addback is limited to $10,000 ($5,000 for married filing separately) and is reported on line 17b of the Maryland Form 502. Maryland will accept any reasonable interpretation of the limitation reported on line 17b. A reasonable interpretation of the law includes the following example: you, a single filer, paid $8,000 in real property taxes and $4,000 in Maryland state income taxes, Maryland will accept an addback of state income tax of $2,000 on Line 17b. In this example, the real estate taxes make up $8,000 of your $10,000 limitation and only $2,000 are required to be added back as state income taxes.

Increased pension exclusion - Maryland's maximum pension exclusion, which is available to qualifying taxpayers who are age 65 or older; are totally and permanently disabled; or have a spouse who is totally and permanently disabled, increased to $33,100 for tax year 2020.

Pension exclusion for qualifying retired correctional officer, law enforcement officer or fire, rescue, or emergency services personnel - Pursuant to House Bill 296 (Acts of 2018), the pension exclusion for Retired Law Enforcement Officer or Fire, Rescue, or Emergency Services Personnel has expanded eligibility to include retirement income of correctional officers. Up to a $15,000 subtraction for resident retired law enforcement officers, fire, rescue and emergency personnel who are at least 55 years old and (1) were employed by the State, a political subdivision of the State, or the federal government, and (2) receive pension income related to their above employment.
