Accounting for Fontana’s industrial and logistics base
Fontana grew up around heavy industry, from its Kaiser Steel roots to today’s dense mix of manufacturing, food processing and packaging, and one of the fastest-growing warehousing and e-commerce distribution footprints in the Inland Empire. Its position next to major freeways and close to the ports has made logistics central to the local economy.
For Fontana business owners, that means real exposure across several tax agencies at once: trucking and fuel tax, sales-and-use tax on inventory and equipment, and heavy use of drivers and contractors that draws EDD worker-classification scrutiny. G&S Accountancy helps the carriers, warehouses, manufacturers, and contractors in Fontana stay compliant and defend themselves when an agency has questions.
We are based just up the road in Rancho Cucamonga, so Fontana owners get a local, Inland Empire CPA firm that already understands trucking and logistics accounting inside out.
