I really don't understand how it is supposed to help small businesses to incent them to buy huge gas-guzzlers like Hummers but not more fuel-efficient vehicles for their businesses. Seriously, WTF?
Federal tax rules that took effect last month allow a credit of up to $3,150 for anyone buying a hybrid car. The credit is the same regardless of tax bracket.However, owners of small businesses who buy a Hummer, Ford Excursion or other SUV weighing more than 3 tons get a deduction of up to $25,000 — depending on tax bracket — if they use the vehicle exclusively for work.
The benefits don't stop there. Once they subtract the $25,000 from the cost of their 3-ton SUV, small business owners can deduct the depreciation on the remaining amount. Someone who bought a $60,000 SUV, for example, can claim the remaining $35,000 over six years.
No such luck for small business owners who buy cars weighing less than 3 tons. No matter how much the vehicles cost, they can claim just $15,535 in depreciation over six years and $1,675 each additional year.
