Net earnings from self-employment 

Net earnings from self-employment means your net earnings from self-employment as defined under Section 1402(a) of the Internal Revenue Code (IRC). Generally, this is the amount computed on federal Form 1040, Schedule SE, Section A, line 4 or Section B, line 6 depending on which section you are required to complete.

  • Section 1402(b) defines self-employment income subject to social security taxes. However, in computing the amount of net earnings from self-employment subject to the MCTMT, Section 1402(b), including the annual limitation on the amount of net earnings from self-employment subject to social security tax under Section 1402(b)(1) does not apply.

NOTE: Under IRC Section 1402, income from certain employment is treated as income from a trade or business and is reported on federal schedule SE as net earnings from self-employment. Accordingly, the income is included in an individual's computation of net earnings from self-employment allocated to the MCTD and is subject to the MCTMT.

Types of employment treated as a trade or business under IRC Section 1402 include but are not limited to:

  • services performed by a United States citizen employed by a foreign government, the United Nations, or other international organizations;
  • services performed by a church employee if the church or other qualified church-controlled organization has a certificate in effect electing an exemption from employer social security and Medicare taxes; and
  • qualified services performed by a minister, a member of a religious order who has not taken a vow of poverty, or a Christian Science practitioner or reader.

Net earnings from self-employment allocated to the MCTD

Net earnings from self-employment allocated to the MCTD means your net earnings from self-employment that are attributable to a business carried on within the MCTD.

  • If all of your business activity is carried on within the MCTD, all of your net earnings from self-employment are allocated to the MCTD.
  • If you carry on business activities both inside and outside of the MCTD, only a portion of your net earnings from self-employment are allocated to the MCTD.
    • You must allocate those net earnings for purposes of:
      1. determining whether or not the annual threshold for the applicable tax year has been met, and
      2. computing the amount of the MCTMT due.
  • Allocation is done using the same rules that apply for purposes of the allocation of business income earned in and out of New York State under the personal income tax rules.

    Accordingly, if you keep books and records that:
        • fairly and equitably show net earnings from self-employment from business activity in the MCTD, you may compute the part to be allocated to the MCTD from those books and records.
        • do not fairly and equitably show the net earnings from self-employment in the MCTD, you must allocate to the MCTD the part of your net earnings from self-employment using the formula method (business allocation percentage) or another method that has been authorized by the Commissioner of Taxation and Finance.

  • For more information on the business allocation method see Form IT-203-A, Business Allocation Schedule for business carried on both in and out of New York State (or the Metropolitan Commuter Transportation District (MCTD)).
  • Partnerships or limited liability companies doing business in the MCTD must provide the MCTD allocation percentage to allow each partner or member to determine the amount of the MCTMT due.

Business activity

Business activity is carried on inside the MCTD if you have maintain, operate, or occupy desk space, an office, a shop, a store, a warehouse, a factory, an agency, or other place located in the MCTD where your business matters are systematically and regularly carried on. Similarly business activity is carried on outside of the MCTD you have, maintain, operate, or occupy desk space, an office, a shop, a store, a warehouse, a factory, an agency, or other place located outside the MCTD where your matters are systematically and regularly carried on.

If you do not have, maintain, operate, or occupy desk space, an office, a shop, a store, a warehouse, a factory, an agency, or other place located in or out of the MCTD, business is carried on within the MCTD if activities in connection with your business are conducted within the MCTD with a fair measure of permanency and continuity.
