All capital gains (long-term and short-term) are reported on Form 8949 and Schedule D is used to calculate a net capital gain or loss. If there is a net gain that is all short-term, then the short-term gain will be taxed at the taxpayer's regular income tax rate; however, if there are long-term losses, these are allowed to offset the short-term gains.
Capital gains and losses are entered on Form 1099-B in the TaxAct program and then reported on Form 8949 and Schedule D.
