This is correct. The IRS says when it officially ends. Some sales people barely even know how to sell cars. They might be lying or confused to pressure you into buying now but that doesn't make any sense since it's already past the 1st!Yes. It's a fed income tax CREDIT. It ends two calendar quarters after they pass 60,000 sales and has nothing to do with the end of the year. They may have been thinking of the state tax sales DEDUCTION for your federal income tax in some states. It's not a refund.
VW hasn't released sales numbers so I estimate them here. Here are some charts and details on how the tax credit works and forms you may need. http://www.myturbodiesel.com/1000q/TDItaxcredit.htm
From my estimates, I believe the fed income tax credit $1300 or $1700 will end 6/10.
