Conklin & de Decker last month released the 2008 State Tax Guide for General Aviation. The guide contains the latest taxes and fees for all 50 states, as well as sales and use tax applicable to aircraft sales, ownership, lease, parts and labor. The 2008 edition allows users to compare tax rates and exemptions for up to three states side by side and includes common exemptions from state sales tax, in addition to common carrier, occasional sales, fly-away and trade-in credits. The guide is available via the Internet or on CD-ROM.
