I believe the Desktop Business program on Windows is the same as the personal Home & Buisness version. You can do them 2 ways, either Online using QEF Quick Employer Forms or on your Desktop. If you pick Create forms on Desktop you can only print and mail them.
And you can only install the Business program on a Windows Desktop computer. There is no online version unless you use the Online Live Service version . The Online Business versions are a lot more expensive. The Online Business is $739 for Live Assisted Business and $1,749 for Live Full Service Business.
