Section 125-210-.04 - Tax and interestA.Tax. The tax rate on qualified telecommunications equipment equals the mill rate for the municipality where the equipment is located. The rate is applied to the product of the just value of the qualified telecommunications equipment in the municipality multiplied by the municipality's certified ratio as reported to MRS on the most recently filed Municipal Valuation Return. Although the municipal mill rate and certified ratio are used to calculate the tax, the excise tax on qualified telecommunications equipment owned or leased by a telecommunications business is assessed by MRS and paid to the State rather than the municipality. B.Interest. Interest applies to late payments of telecommunications excise tax. The rate of interest is calculated pursuant to 36 M.R.S. §186, and is charged from the date the payment is due until the tax is paid, compounding monthly. 18-125 C.M.R. ch. 210, § .04
