Dear Sarah Jenkins (SSN: 000-12-3456), regarding your 2024 tax preparation, I have compiled your investment activity. First, regarding your short-term holdings, we have several transactions. Your 1099-B reports show total proceeds of $12,500 with a cost basis of $10,200 for your standard stocks with no adjustments. Additionally, per your Form 8949 reporting (Box A), you had short-term proceeds of $4,000 and a cost basis of $4,500, resulting in a $500 loss. You had no Box B or Box C activity this year. We also noted a $200 short-term loss carryover from 2023. Moving to long-term gains, your standard 1099-B transactions yielded $25,000 in proceeds against a basis of $18,000. Under Box D, you had long-term sales of $8,000 with a cost of $5,000. Please note you received $1,200 in capital gain distributions from your mutual funds, which are recorded as long-term. You do not have any Section 1250 gains or 28% rate gains, and you confirmed you did not dispose of any investment in a qualified opportunity fund during the 2024 tax year. I have verified your Form 1040 shows qualified dividends on line 3a, so we will need to attach the appropriate worksheets. Please review these figures before I finalize the filing with the IRS. Best, Mark the Accountant.
