Ideal for traders, tax professionals, and investors managing multiple brokerage accounts who need a faster, automated way to consolidate and analyze their 1099-B tax forms.
After the success of Auto-StockTrader, I realized managing tax forms across multiple accounts and brokerages was a challenge. My accountant even recommended filing for an extension due to the large number of 1099 tax forms, a result of the primary investment strategy used by users of my Auto-StockTrader repository. Additionally, some accountants charge hefty fees—$50-75 per additional tax form. TaxMerge was created to tackle this issue; it aims to simplify this process, particularly in calculating the final short and long-term net realized gains/losses for a tax year.
