Tradelog Software for tax preparation
Tradelog Software does all the obvious things for traders' taxes; which is nice, because the IRS does not.
Broker 1099-B reports are often useless for tax reporting since the IRS has different rules for taxpayers than they do for brokerages. No, you did not read that wrong! Let me say that again: The IRS has different reporting rules for taxpayers than they do for brokerage 1099s. And in many cases (maybe as high as 90%) your brokerage 1099-B will not match with what you, the taxpayer, are required to report on Schedule D Form 8949.
Greene recommends it:
We frequently find errors in other programs and solutions on wash sales, tax treatment and more. Many of these programs or solutions are geared toward the needs of brokerage firms, and IRS rules for broker-issued securities 1099-Bs are materially different from what taxpayers need to report on their Form 8949/Schedule D. Brokers are permitted to report potential wash sales based on "identical positions," whereas taxpayers must report actual wash sales based on "substantially identical positions" (between stocks and stock options based on the same symbol). Many tax preparers get lazy and import broker-issued securities 1099-Bs into their tax preparation software which is a huge mistake, because it will either overstate or understate trading gains and losses
