COMPOSITE PASS-THROUGH ENTITY INCOME TAX RETURN INSTRUCTIONS

GENERAL INSTRUCTIONS

Pass-through entities (PTEs) may use Form 510C to file a composite income tax return on behalf of eligible nonresident individual members . Nonresident members other than individuals may not participate in the composite return. The Maryland tax of each nonresident individual member is calculated using the rate of 5 .75% plus the special nonresident tax of 2 .25% . Note: A single member entity cannot file a composite return.

SPECIFIC INSTRUCTIONS

Who may use this form. Nonresident individual members of a PTE doing business in the State who meet the composite return requirements contained in Technical Bulletin 6 and elect to be included in a composite return may not be required to file Maryland nonresident returns individually . Instead, the PTE doing business in the State may file a composite return on behalf of such nonresident individual members if: 1 . Form 510C accurately reflects the Maryland taxable income and tax liability of each individual member shown on the return; 2 . Form 510C Schedule A is attached containing all required information for each individual member; and, 3 . The PTE pays the tax, interest and penalty due by each individual member shown on the return . Any overpaid amount will be refunded to the PTE. For more information, Technical Bulletin 6 may be obtained from our website at . Line 2 Enter the number of eligible nonresident individual members who have elected to be included on this composite return . Fiduciaries are not eligible and cannot be included . Line 4 Enter the total exemption amount reported on Column C, Form 510C Schedule A . The exemption amount allowed for each nonresident individual member must be determined separately based on the individual member's filing status. Gener ally, you are entitled to claim qualified exemptions on the Maryland return . The amount of your Maryland exemption may be limited by the amount of your federal adjusted gross income . See Instruction 10 of Form 505, Maryland Nonresident Income Tax Return to determine the exemption amount before multiplying it by the Maryland income factor, which is the nonresident's Maryland adjusted gross income (generally from Form 510C, Schedule A, Column F) divided by the nonresident's federal adjusted gross income (FAGI) . If it is impracticable to determine all of the separate Maryland income factors, then the factor must be determined by using line 6 of Form 510 as the numerator (excluding the portion applicable to nonresident fiduciary members) and line 2 of Form 510 as the denominator (See Technical Bulletin 6) . Line 5 Enter the total standard deduction amount reported on Column D, Form 510C, Schedule A . The standard deduction amount allowed for each nonresident individual member must be determined separately based on the individual member's Maryland adjusted gross income, and then prorated by the nonresident's Maryland income factor . See Instruction 15 of Form 505 for determining the standard deduction amount . See the instruction for line 4 for the nonresident individual member's Maryland income factor . Line 7 Enter the total PTE flow-through decoupling modification amount reported on Column E, Form 510C. No flowthrough addition or subtraction modifications, other than the modification required as a result of Maryland's decoupling from the additional depreciation allowance and special 2-year net operating loss carryback provisions may be claimed on a composite return . Line 15 If there is a balance due on line 13, interest may be due as result of late filing of Form 510C and payment of tax . Interest is due at the rate of 11 .4825% annually or 0 .9568% per month for any month or part of a month that a tax is paid after the original due date of the return through 12/31/25 . The annual interest rate may change after 12/31/25 . For additional information, visit marylandtaxes.gov . The Comptroller of Maryland will calculate the interest and penalty for failure to pay the required amount of tax and notify the pass-through entity of any balance due . Line 16 Total Balance Due . Add the amounts on lines 13 and 15 and enter the result, or, if the amount on line 15 exceeds line 14, enter the difference. The total amount due must be paid with the filing of Form 510C.
