Cal. Code Regs. tit. 18 § 1583
Modular systems furniture is tangible personal property, whether or not affixed to realty. A contract to sell and install modular systems furniture is a contract for the sale of tangible personal property and is not a construction contract. Persons who contract to sell and install modular systems furniture are retailers of the items which they sell and install, and tax applies to the entire contract price less those charges excludable from gross receipts or sales price pursuant to Sections 6011 and 6012 of the Revenue and Taxation Code. Retailers who claim a deduction for such charges should maintain complete and detailed records to support the amounts claimed. Such records should include, but not be limited to, a separate accounting of charges for installation labor, such as labor to affix, bolt, fasten, or hardwire panels to realty and labor to fasten or affix fully constructed components to fully constructed panel systems or other components. Charges for fabrication labor, such as labor to attach, assemble, connect, construct, or fabricate panel systems or components, labor to attach or connect one panel to another to form workstations or cubicles, and labor to construct or fabricate the individual panels, components, or accessories are subject to tax.
For contracts to sell and install modular systems entered into on or after October 1, 1999, ten percent (10%) of the total contract price, excluding charges attributable to freestanding desks, credenzas, lateral files, bookcases, worktables, returns, convergents, corner units, storage towers, chairs, footrests, and other property not attached to panels, other components, or realty, but including all other charges, will be presumed to be a charge for labor to install or apply the property sold. Retailers may claim the ten percent (10%) labor deduction in lieu of separately accounting for the actual installation charges incurred.
