If you have only income from self-employment
and no expenses, there is no need to upgrade from Deluxe. If you do have
expenses, however, that will trigger an upgrade to the TurboTax Self-Employed
edition.
Expenses, however, could reduce your total
income and overall tax bill. Including SE tax (social security/medicare tax) of
15% and a 15% tax rate, $280 of expenses would save you around $84 in taxes. At
25% tax bracket, it would mean a $112 saving, and so on.
