With 93,000 units of professional tax software sold in the second quarter ended January 31, Intuit continues to have by far the largest share of the market. But the number of units continues to slip as the most recent total is down from 95,000 in last year's corresponding quarter and off from 97,000 in the same quarter in fiscal 2009. The company's peak came in the second quarter of fiscal 2007 when Intuit sold 102,000 units. Meanwhile, Intuit regained retail market share and reported gains in online consumer tax sales for the period.
