Michigan Business Tax

Generally, securities, such as stocks, bonds and similar intangibles, will be capital assets under section 1221 of the IRC unless the securities are inventory to the taxpayer. Receipts from the sale of capital assets could be taxable in both the business income and modified gross receipts tax bases of the MBT. Business income is generally defined as "that part of federal taxable income derived from business activity." MCL 208.1105(2). To the extent the capital gain from the sale of the securities is derived from the business activity of the taxpayer, the gain must be included in the business income tax base of the MBT. For this purpose, the capital gain will be computed the same as it was federally, which is proceeds from the sale minus basis. The result will flow to the MBT return if the gain is derived from the business activity of the taxpayer. The "cost" or basis is the acquisition cost of the asset just as it is for federal purposes and is not the fair market value as of January 1, 2008, the date that the MBT went into effect.

For purposes of the modified gross receipts tax base, if the securities are sold at a gain then the proceeds of the sale of the securities minus any gain from the sale, to the extent that the gain was included in federal taxable income, will be excluded from the tax base.

If the securities were held for investment purposes by and are sold by an individual, estate, trusts or family limited partnerships (FLIP) that is specifically established for estate planning purposes, then the receipts on the sale of the securities are not taxable in either MBT tax base. MCL 208.1105(2) and 1111(v)(v).
