Why Turbo Tax doesn't apply the minimis tax rule for the sale of bonds acquired at market discount? will cause in incorrect adjustments and incorrect interest reported.

Market discount treatment for bonds sales.

[Mike9241]

• The de minimis tax rule sets the threshold at which a discount bond should be taxed as a capital gain rather than as ordinary income. The rule states that a discount that is less than a quarter-point per full year between its time of acquisition and its maturity is too small to be considered a market discount for tax purposes. This only applies to municipal bonds

probably because TT has no way of knowing this and doesn't what to spend the resources necessary to include the programming required to calculate this. I would guess that taxpayers with a significant muni portfolio use a pro for their tax returns. I've never seen this provision provided for even in pro software and I've used many different prof products. if you hold the munis through a broker why aren't they providing the necessary info.
