The present true and actual value of all other property shall be deemed by all assessors and boards of assessment appeals to be the fair market value thereof and not its value at a forced or auction sale.
(b) (1) For the purposes of this subsection, (A) “electronic data processing equipment” means computers, printers, peripheral computer equipment, bundled software and any computer-based equipment acting as a computer, as defined in Section 168 of the Internal Revenue Code of 1986, or any subsequent corresponding internal revenue code of the United States, as from time to time amended; (B) “leased personal property” means tangible personal property which is the subject of a written or oral lease or loan on the assessment date, or any such property which has been so leased or loaned by the then current owner of such property for three or more of the twelve months preceding such assessment date; and (C) “original selling price” means the price at which tangible personal property is most frequently sold in the year that it was manufactured.

If so adopted, the present true and actual value of tangible personal property, other than motor vehicles, shall be determined in accordance with the provisions of this subsection. If such property is purchased, its true and actual value shall be established in relation to the cost of its acquisition, including transportation and installation, and shall reflect depreciation in accordance with the schedules set forth in subdivisions (3) to (6), inclusive, of this subsection. If such property is developed and produced by the owner of such property for a purpose other than wholesale or retail sale or lease, its true and actual value shall be established in relation to its cost of development, production and installation and shall reflect depreciation in accordance with the schedules provided in subdivisions (3) to (6), inclusive, of this subsection.

(8) The present true and actual value of leased personal property other than motor vehicles shall be determined in accordance with the provisions of this subdivision. Such value for any assessment year shall be established in relation to the original selling price for self-manufactured property or acquisition cost for acquired property and shall reflect depreciation in accordance with the schedules provided in subdivisions (3) to (6), inclusive, of this subsection. If the assessor is unable to determine the original selling price of leased personal property, the present true and actual value thereof shall be its current selling price.
(9) With respect to any personal property which is prohibited by law from being sold, the present true and actual value of such property shall be established with respect to such property's original manufactured cost increased by a ratio the numerator of which is the total proceeds from the manufacturer's salable equipment sold and the denominator of which is the total cost of the manufacturer's salable equipment sold. Such value shall then be depreciated in accordance with the appropriate schedule in this subsection.
(10) The schedules of depreciation set forth in subdivisions (3) to (6), inclusive, of this subsection shall not be used with respect to videotapes, horses or other taxable livestock or electric cogenerating equipment.
(11) If the assessor determines that the value of any item of personal property, other than a motor vehicle, produced by the application of the schedules set forth in this subsection does not accurately reflect the present true and actual value of such item, the assessor shall adjust such value to reflect the present true and actual value of such item.
(12) Nothing in this subsection shall prevent any taxpayer from appealing any assessment made pursuant to this subsection if such assessment does not accurately reflect the present true and actual value of any item of such taxpayer's personal property.

Where assessors adopt rule of valuation conflicting with statute, remedy is by appeal to board of relief. 43 C. 309. If assessors adopt rule of valuation, assessment may be reduced on appeal to conform to such rule. 63 C. 18, 322. No distinction in law between assessed and actual value of real estate. 72 C. 372. Statute does not apply unless there is a market; if no market, then fair value must be otherwise ascertained. 99 C. 336. Cited. 102 C. 210; 105 C. 581. On capitalization of income, see 119 C. 5. Where market value not ascertainable, true and actual valuation must be determined by some other method. 122 C. 230. Property may be found to have market value in the absence of evidence of other sales of like property in open market. 125 C. 172. History of statute; valuation a question of fact for trier; not erroneous to consider reproduction cost and capitalization of income as well as actual sales prices in determining fair market value. 131 C. 575. Methods of determining “true and actual value”. 146 C. 578. Best test for determination of value is ordinarily that of market sales; land residual method discussed; value of real estate must be gauged by conditions prevailing over a period of time. Id., 669. Capitalization of net income method of valuation discussed. Id., 681. Cited. 149 C. 32. Fair market value can be determined from figure fixed by actual sales where there are sales, in ordinary course of business of other properties comparable in kind and location; where property was dam and not readily marketable, proper to resort to other means of ascertaining value as replacement cost minus depreciation. Id., 453. Although present value of all other property is fair market value, value of “farmland” is based on its current use without regard to neighborhood land use, even where plaintiffs had sold adjoining land at neighborhood values. 156 C. 107. Where plaintiffs failed to apply for classification of their farm as farmland under Sec. 12-107c, it was properly valued at its fair market value. Id., 437. Cited. 162 C. 87. Where golf course is classified as open space, it is valued on its current use and not at the highest value of farm land; in valuation of open space at current use, legislative intent is that current use value be less than what its fair market value might be; in determining “current use”, no particular formula is required. 174 C. 10. Cited. Id., 380; Id., 556. Fair market value is price that would probably result from fair negotiations between willing seller and willing buyer. 175 C. 301. Cited. 178 C. 100; Id., 295. Fair market value not determined where the one sale cited was not comparable, value realized from a forced or bid sale. Id., 606. Cited. 203 C. 425; 210 C. 233; 226 C. 407; 228 C. 23; 231 C. 731; 240 C. 192; Id., 422; 241 C. 382.

No other method legal for assessment if there is a market value. 8 CS 540. Cost of reproduction less depreciation proper if there is no market value. 11 CS 241. If most recent sales in same vicinity are of property held by bank, they are not a fair criterion for market value. 12 CS 47. Extensive discussion of various methods of valuation. 20 CS 476.
