S.C. Code Ann. § 4-29-67
(B) In order for property to qualify for the fee as provided in subsection (D)(2):
(4)
(b)
(C)
(2) From the end of the property tax year in which the investor and the county execute the initial lease agreement, the investor has five years in which to complete its investment for purposes of qualifying for this section. If the investor does not anticipate completing the project within five years, the investor may apply to the county before the end of the five-year period for an extension of time to complete the project. If the county agrees to grant the extension, the county must do so in writing, and a copy must be delivered to the Department of Revenue within thirty days of the date the extension was granted. The extension may not exceed two years in which to complete the project.
There is no extension allowed for the five-year period in which to meet the minimum level of investment. If the minimum level of investment is not met within five years, all property under the lease agreement or agreements reverts retroactively to the payments required by Section 4-29-60. The difference between the fee actually paid by the investor and the payment which is due under Section 4-29-60 is subject to interest as provided in Section 12-54-25(D).
Unless property qualifies as replacement property under a contract provision enacted pursuant to subsection (F)(2), any property placed in service after the five-year period, or seven years in the case of a project which has received an extension, is not part of the fee agreement under subsection (D)(2) and is subject to the payments required by Section 4-29-60 if the county has title to the property, or to property taxes as provided in Chapter 37 of Title 12 if the investor has title to the property.
For purposes of those businesses qualifying under Section 4-29-67(D)(4), the five-year period referred to in this subsection is eight years and the seven-year period is ten years.
(D) The inducement agreement must provide for fee payments, to the extent applicable, as follows:
(1)
(2) After property qualifying under subsection (B) is placed in service, an annual fee payment determined in accordance with one of the following is due:
(a) an annual payment in an amount not less than the property taxes that would be due on the project if it were taxable, but using an assessment ratio of not less than six percent, except as provided in subsection (D)(4), and a fixed millage rate as provided in subsection (G), and a fair market value estimate determined by the South Carolina Department of Revenue as follows:
(3) At the conclusion of the payments determined pursuant to items (1) and (2) of this subsection, an annual payment equal to the taxes due on the project as if it were taxable. When the property is no longer subject to the fee under subsection (D)(2), the fee or property taxes must be assessed:
(4)
(a) The assessment ratio may not be lower than four percent:
(F) With regard to calculation of the fee provided in subsection (D)(2), the inducement agreement may provide for the disposal of property and the replacement of property subject to the fee as follows:
(1)
(2) Any property which is placed in service as a replacement for property which is subject to the fee payment may become part of the fee payment as provided in this item:
(G)
(H)
(I) Investment expenditures incurred by any investor in connection with a project, or relevant phase of a project for those projects completed and placed in service in more than one year, qualify as expenditures subject to the fee in subsection (D)(2), so long as these expenditures are incurred:
(2) before the end of the applicable time period for investments referenced in subsection (C)(2) and (C)(3).
An inducement agreement must be executed within two years after the date on which the county takes action reflecting or identifying the project or proposed project or investment including, but not limited to, the adoption of an inducement or similar resolution by county council; otherwise, only investment expenditures made or incurred by any investor after the date of such inducement agreement in connection with a project shall qualify as expenditures subject to the fee in subsection (D)(2).
(J)
(1) Subject to subsection (K), project investment expenditures which are incurred within the applicable time period provided in subsection (I) by an entity whose investments are not being computed in the level of investment for purposes of subsections (B) or (C) shall qualify as investment expenditures subject to the fee in subsection (D)(2) where:
(K)
(1) Property which has been previously subject to property taxes in South Carolina will not qualify for the fee except as provided in this subsection:
(L)
(O)
(3) All transfers undertaken with respect to the project to effect a financing authorized under subsection (O) must meet the following requirements:
(U)
(W)
(X) Except as otherwise expressly provided in subsection (C)(2), any loss of fee benefits under this section shall be prospective only from the date of noncompliance and, subject to subsection (U), only with respect to that portion of the project to which such noncompliance relates; provided, however, that such loss of fee benefits cannot result in the recovery from the fee-paying entity of fee payments for more than:
(AA)
(BB) Notwithstanding any other provision of this section, the fair market value of property of a pharmaceutical company investing more than four hundred million dollars in one county in this State is the lower of the fair market value estimate (1) as determined pursuant to subsection (D)(2)(a)(i), or (2) as determined by the county in which the investment is located as follows:
(b) for personal property, using the original income tax basis for South Carolina income tax purposes, less any such basis amount attributable to cost overruns, including capitalized interest overruns, and less depreciation allowable for property tax purposes, except that the investor is not entitled to any extraordinary obsolescence.
This subsection applies only to property placed in service before January 1, 2000.
