CT-3-A/BC-I

Printer-Friendly Version (PDF)

Filing requirements

Form CT‑3‑A/BC is an individual certification which includes a detail schedule of the member’s business and investment capital and business apportionment line items.

Each member, including non‑taxpayer members, of the New York State combined group must annually file Form CT-3-A/BC except for the taxpayer that is the designated agent of the combined group (the corporation responsible for filing Form CT‑3‑A, General Business Corporation Combined Franchise Tax Return).

E-filers

If you electronically file Form CT‑3‑A/BC, you must e-file it separately from Form CT‑3‑A. Do not attach it as a PDF. For a list of e-file software, see Approved software developers for corporation tax e-file or visit www.tax.ny.gov (search: software).

Paper filers

If you file Form CT‑3‑A/BC by paper, you must:

1. enter the employer identification number (EIN) of the designated agent in the space provided, and
2. submit Form CT-3-A/BC to the designated agent who must file it with Form CT‑3‑A. 

Reporting period

Use this form for:

• calendar year 2024,
• fiscal years that begin in 2024 and end in 2025, and
• tax years of less than 12 months that begin on or after January 1, 2024, but before January 1, 2025.

You can also use the 2024 form if:

• you have a tax year of less than 12 months that begins and ends in 2025, and
• the 2025 return is not yet available at the time you are required to file the return.

In this case you must show your 2025 tax year on the 2024 return and take into account any tax law changes that are effective for tax years beginning after December 31, 2024.

All filers must complete the beginning and ending tax year boxes in the upper right corner on page 1 of the form.

Filing your final return

Mark an X in the Final return box on Form CT‑3‑A/BC if the group member is a:

• domestic corporation that ceased doing business, employing capital, owning or leasing property or deriving receipts from activity, in New York State during the tax year and wishes to dissolve; or
• foreign corporation that is no longer subject to the franchise tax in New York State. Note: If the foreign corporation remains as a nontaxable member of the combined group, that foreign corporation must continue to file Form CT‑3‑A/BC.

Do not mark an X in the Final return box:

• if you are only changing the type of return that you file (for example, from Form CT‑3‑A to CT‑3‑S); or
• in the case of a merger or consolidation.

On your final return, include:

• the full profits from any installment sales made in the final tax year; and
• any remaining profits not yet received from all prior years’ installment sales.

Each member of the combined group must include these amounts in its own separate federal income (as that member reports on its Form CT-3-A/BC, Part 1, line 9 or, in the case of the designated agent, on Form CT-3-A, line F).

For information on voluntary dissolution and surrender of authority, see Instructions for voluntary dissolution of a New York corporation or visit www.tax.ny.gov (search: dissolution) and Instructions for surrender of authority by a foreign business corporation or visit www.tax.ny.gov (search: surrender).

Line instructions

Part 1: Group member’s general information

Line 1

If during the tax year you do business, employ capital, own or lease property, maintain an office, or derive receipts from activity, in the Metropolitan Commuter Transportation District (MCTD), you are subject to the metropolitan transportation business tax (MTA surcharge).

The MCTD includes the counties of New York, Bronx, Kings, Queens, Richmond, Dutchess, Nassau, Orange, Putnam, Rockland, Suffolk, and Westchester.

To determine if you are subject to the surcharge, see Form CT‑3‑M, General Business Corporation MTA Surcharge Return.

Mark an X in the appropriate box. If Yes, the combined group must file Form CT‑3‑M.

Line 5

If you are a real estate investment trust as defined in Internal Revenue Code (IRC) § 856 that is subject to federal income tax under IRC § 857, or a regulated investment company as defined in IRC § 851 that is subject to federal income tax under IRC § 852, mark an X in the box.

Line 7

A nontaxpayer member of the combined group is not required to pay the fixed dollar minimum tax. However, it is required to report all other items included in all other calculations of Form CT‑3‑A, including receipts for apportionment purposes.

Line 9

For this purpose, Federal separate taxable income means the amount you calculated (or if your federal consolidated group is not the same as your New York combined group, the amount you would have calculated if the federal consolidated group was comprised of the same members as the New York State combined group):

• in accordance with the provisions of the IRC that govern the calculation of taxable income for separate return purposes, but
• subject to Treasury Regulations § 1.1502-12.

Line 16

Enter the member’s share of the amount reported on the designated agent’s Form CT‑3.4, Net Operating Loss Deduction (NOLD), line 5.

Line 17

Generally, the amount entered is the member’s share of the amount reported on the designated agent’s Form CT‑3.4, line 7.

Part 2: Group member’s fixed dollar minimum tax and prepayments

Note: If you are a nontaxpayer member of the combined group, skip lines 1 and 2.

Section 1

Lines 1 and 2 

Each member of the combined group that is subject to tax under Article 9‑A must calculate its own fixed dollar minimum tax on Form CT‑3‑A/BC. On line 1, enter your New York receipts from Part 6, column C, line 55. To avoid an erroneous assessment or a delay of your refund, you must enter an amount on line 1. If you do not have New York receipts, enter 0 on line 1.

Enter the applicable fixed dollar minimum tax on line 2 of this form. To determine the fixed dollar minimum tax, use the appropriate table below. If the combined group qualifies as a qualified New York manufacturer, then each of the members in the combined group that are required to pay the fixed dollar minimum tax use the applicable lower fixed dollar minimum tax rate. For the qualifying criteria of a qualified New York manufacturer, see Form CT-3-A-I, Instructions for Form CT-3-A, Part 1, Section A, lines 2 and 4.

For a member of a combined group to use the tax rate for a qualified emerging technology company, all members of the group must be qualified emerging technology companies, under New York State Public Authorities Law § 3102‑e(1)(c), except that the $10 million limitation under § 3102‑e(1)(c)(1) does not apply. For more information, see TSB‑M‑12(9)C, Clarification of Qualifications for Qualified Emerging Technology Company (QETC) Tax Credits.

Do not pay the tax with Form CT-3-A/BC. Enter the fixed dollar minimum tax on line 2 of this form and also include it on Form CT‑3‑A, Part 2, line 4b.

Short periods: Fixed dollar minimum tax

To calculate the New York receipts for short periods (tax periods of less than 12 months):

1. Divide the amount of New York receipts for the tax year by the number of months in the tax year.
2. Multiply the result by 12.

The fixed dollar minimum tax may be reduced for short periods as follows:

Section 2

Note: Complete this schedule only if the corporation filing Form CT‑3‑A/BC made prepayments, had prepayments attributable to it, or had amounts credited to it, independent from being a member of the current combined group filing this Form CT‑3‑A/BC. If you need more space, write see attached in this section, and attach a separate sheet showing all relevant prepayment information.

Line 3

Determine the amount of payment made independent from being a member of the current combined group by completing the Worksheet for Part 2, line 3 below. If you are completing line 3 for the MTA surcharge, read New York State mandatory first installment as MTA surcharge mandatory first installment, and read column A as column B, respectively in the Worksheet.

Line 8 

In the Franchise tax amount column, enter the sum of the amounts reported on Part 2, lines 21 and 26 of the Form CT‑3 that the member filed for the tax period immediately prior to the tax period for which this return is being filed.

If for that prior period, the member filed on Form CT‑3‑A as a member of a different combined group, enter the sum of the amounts reported on Part 2, lines 22 and 27 of Form CT‑3‑A that is attributable to the member.

In either instance, if Form CT‑3‑M was filed for that prior period, enter in the MTA surcharge amount column the amount from line 15 of the prior Form CT‑3‑M that is attributable to the member.

Parts 3, 4, and 5

For Parts 4 and 5, the line numbers and text on Form CT‑3‑A/BC correspond to the line numbers of Form CT‑3‑A. For part and line instructions, refer to the corresponding line instructions in Form CT‑3‑A‑I.

Note: Part 3 and Part 4, lines 7 through 15, and line 19, are not included on Form CT‑3‑A/BC because individual member specific information is not required for these lines of Form CT-3-A.

Part 6: Calculation of business apportionment factor

Line 8

Only mark an X in the box when the fixed percentage method is in effect for the entire combined group as the election is binding on all members of the group.

Lines or section headings with a qualified financial instrument (QFI) box

Only mark an X in the QFI box when the QFI box on the corresponding lines (in the case of lines 11 and 12) or next to the corresponding section headings on Form CT‑3‑A, Part 6 has been marked with an X.

Corresponding lines on Form CT-3-A

For this part, the line numbers for this form correspond to the line numbers on Form CT‑3‑A. For part and line instructions, refer to both the corresponding line instructions in Form CT‑3‑A‑I and the instructions below.

Columns A and B

For all lines involving the calculation of net gains, net income, or net interest, amounts less than zero are allowed and must be entered where applicable on Form CT‑3‑A/BC. Amounts less than zero are allowed in columns A and B because these amounts must be netted on a combined basis to amounts not less than zero on Form CT‑3‑A in determining the apportionment factor.

Use a minus sign (‑) to report amounts less than zero (not parentheses or brackets).

In column B (New York State), generally New York State receipts amounts should be calculated on a combined group basis, using the applicable apportionment rule or fraction as calculated for the combined group for each line.

Example: For line 45, in column B, a combined member would multiply those receipts by a fraction, the numerator of which is the total miles of the combined group within New York State and the denominator of which is the total miles of the combined group within and outside New York State.

Column C

You cannot net such gain, income, or interest to an amount less than zero; therefore, you must enter amounts less than zero as 0 in this column.

In this column, generally New York State receipts amounts should be calculated on a separate company basis using the applicable apportionment rule or fraction, as calculated on a separate company basis, for each line (this includes not taking into consideration intercorporate eliminations when calculating this column).

Example: For line 45, in column C, a combined member would multiply its own separate amount of receipts from the conduct of a railroad business, or a trucking business, or an omnibus business by a fraction, the numerator of which is the total miles of only that combined member within New York State and the denominator of which is the total miles of only that combined member within and outside New York State.

Corporations in the combined group that are not subject to tax under Article 9‑A (franchise tax on general business corporations) do not need to complete this column (New York State fixed dollar minimum).

Use worksheets A, B, and C in Form CT‑3‑A‑I, Part 6 instructions to calculate certain amounts for lines 10, 12, 21, 24, 28, and 30. You must complete these worksheets before you enter the amounts on these lines in this form.

Signature

The return must be certified by the president, vice president, treasurer, assistant treasurer, chief accounting officer, or other officer authorized by the taxpayer corporation.

The return of an association, publicly traded partnership, or business conducted by a trustee or trustees must be signed by a person authorized to act for the association, publicly traded partnership, or business.

If an outside individual or firm prepared the return, all applicable entries in the paid preparer section must be completed, including identification numbers (see Paid preparer identification numbers in Form CT‑1).

Failure to sign the return will delay the processing of any refunds and may result in penalties.
