Filing a Maryland state return for the 2010 tax year required specific forms, deadlines, and instructions from the Comptroller of Maryland and the Internal Revenue Service. Residents who earned income, had Maryland taxes withheld, or needed to claim a refund were required to file a personal income tax return. While the original deadline passed in 2011, many taxpayers still need clear guidance on filing late, requesting copies, or amending a past return.
This guide explains who must file, how to determine if you qualify for a tax credit, and what documents are required, including a Social Security number, income records, and payment information. It also outlines how to electronically file, use direct file, or mail state returns, make payments, check refund status, and request assistance from the department when questions arise.
These instructions remain useful in situations where older filings affect current obligations. You may need to resolve unpaid taxes, confirm refund details, respond to an audit, or provide documentation for business or personal financial purposes. Following the steps and resources provided by the Maryland comptroller, you can complete your return correctly and settle any issues tied to the 2010 tax year.
Form 502 is the main Maryland resident income tax return for 2010. It covers all aspects of calculating Maryland taxes, applying credits, and determining refund amounts or payments due to the state.
Several supplementary forms may be required depending on your situation:
Collect these essential documents before beginning your Maryland tax return preparation:
Enter your complete name, current address, and social security number accurately on the return. Include your spouse's information if married filing jointly, and select the same filing status used on your federal return to ensure consistency.
Start with your federal adjusted gross income from your completed federal return and apply Maryland-specific modifications. Add back items like non-Maryland state bond interest and subtract qualifying pension income, Social Security benefits, and child care expenses up to statutory limits.
Maryland's standard deduction equals 15% of adjusted gross income with specific limits by filing status. Most taxpayers benefit from the standard deduction because the percentage calculation often exceeds the itemizing benefits for middle-income residents.
Personal exemption amounts phase out based on federal adjusted gross income levels, ranging from $3,200 for lower incomes to $600 for the highest earners. Taxpayers age 65 or older or blind receive an additional $1,000 exemption per qualifying person.
Apply the progressive tax bracket rates to your taxable income to determine state tax, then add your county's local income tax rate. Combined state and local taxes create your Maryland tax liability before applying any available credits.
Common 2010 credits include the earned income credit (50% of the federal amount), the child and dependent care credit (32.5% for incomes under $50,000), and the long-term care insurance premium credit. These credits directly reduce your tax liability and may result in refunds exceeding taxes owed.
Compare your tax liability to payments made through withholding and estimated payments during 2010. Attach all W-2 and 1099 forms showing Maryland tax withheld to verify your payment amounts and support your refund claim or balance due calculation.
Maryland offered electronic filing through approved software providers and tax professionals for tax year 2010 returns filed in 2011. Electronic filing provided faster processing times and reduced mathematical errors compared to paper filing methods.
Complete your return using blue or black ink only, carefully sign and date all required sections, and attach all supporting documents in the order specified by the instructions. Mail your return with required attachments to the comptroller's office using the correct address specified in the 2010 tax instructions.
Send completed paper returns to the Comptroller of Maryland, Revenue Administration Division, Annapolis, MD 21411-0001 using reliable postal services. Use certified mail for significant returns to confirm delivery and maintain legal proof of timely filing.
The regular filing deadline for tax year 2010 Maryland returns was April 15, 2011, matching the federal deadline for consistency. Taxpayers who filed for an extension using proper procedures had until October 15, 2011, to submit their completed returns without incurring late filing penalties.
Late filing results in penalties calculated as a percentage of unpaid taxes, plus monthly interest charges that compound over time. Contact the comptroller's office immediately if you cannot meet filing deadlines to discuss available options and minimize financial consequences.
Make checks or money orders payable to "Comptroller of Maryland," include your social security number and "2010" on the memo line for proper account crediting. Electronic payment options were available through the comptroller's secure online system for taxpayers who needed to pay additional taxes.
Unpaid taxes accrue interest at rates established by Maryland law, compounded monthly from the original due date until payment is received. Late payment penalties apply in addition to interest charges and increase the longer taxes remain unpaid.
The comptroller may approve payment plans for taxpayers unable to pay the full amount immediately due to financial hardship. Contact the Collections department at (410) 260-7980 to request a payment arrangement and discuss your financial situation and available options.
Check your refund status by calling the dedicated refund hotline at (410) 260-7701 or 1-800-218-8160 during business hours for automated status updates. You can also use the online refund tracking system by entering your social security number, exact refund amount, and filing status information.
Electronic returns typically process within 2-3 weeks of receipt, while paper returns require 6-8 weeks for complete processing and refund issuance. Complex returns with unusual deductions or credits may require additional review time beyond standard processing periods.
Use Form 502X to amend your 2010 Maryland return if you discover errors or omissions after filing your original return. You generally have three years from the original due date or two years from when you paid the tax to file an amended return and claim additional refunds.
Contact the comptroller's office at (410) 260-7980 to request copies of your filed 2010 return when you need documentation for loans or personal records. There may be fees associated with obtaining copies, and you will need to verify your identity and provide specific information about the requested return.
The comptroller's office provides comprehensive assistance with questions related to 2010 tax returns, archived forms, and historical tax issues. When calling, have your Social Security number, tax year information, and specific questions prepared to ensure efficient service from knowledgeable staff members.

You may qualify for credit for taxes paid to other states during the portion of the year you were not a Maryland resident, which can significantly reduce your overall tax liability. Use the part-year resident section of Form 502 to allocate income and taxes properly.
