Tax preparers need a way to accurately report gambling winnings from slot machines where the W-2G overstates actual profit because it reports the cashout amount instead of net winnings, especially for non-itemizing clients.

Tax software does not handle W-2G slot machine income realistically for non-itemizers; there is no standard method to offset reported winnings with the actual wager amount, forcing preparers to either report inflated income or manually create offset entries.
