If this cost ratio is 35% or greater (75% or greater in the case of servicemen transferring prescription drugs or engaged in graphic arts production), the serviceman is required to register and remit Service Occupation Tax on his selling price, as explained in Section 140.106.
Annual aggregate cost of parts | $ 56,000 |
Marked up selling price of parts | $ 75,600 |
Service or labor charge | $ 20,000 |
Sales of service only | $ 16,400 |
Annual gross receipts | $112,000 |
To figure the cost ratio, divide the annual aggregate cost of parts of $56,000 by the annual gross receipts of $112,000.
$56,000/112,000 = .50 or 50%
The cost ratio is 50%. So, for example, if the serviceman is subject to the 35% threshold, Service Occupation Tax on the serviceman's selling price will be incurred in this instance.
