Dell Small Business offers downloads of Intuit TurboTax Home and Business Federal and State for Windows/Mac bundled with a $25 Dell Gift Card for $79.99. Assuming you'll use the gift card, that's the lowest price we could find by $25, although we saw it for $5 less last month. This software assists with income tax filing for sole proprietors, self-employed, consultants, and 1099 contractors.
