How to Fix the Capital Gain Worksheet Error (Error 408) in TaxWise

This error occurs when a capital gain transaction is incorrectly coded as short-term (A, B, or C) on the Capital Gain (Schedule D) Worksheet, but the holding period indicates it should be long-term.

Steps to Fix the Error in TaxWise

  1. Open the Tax Return

    • Launch TaxWise and open the affected tax return.

  2. Navigate to the Capital Gain Worksheet

    • Locate the Capital Gain Worksheet (linked to Schedule D) in the forms list.

  3. Review the Transaction Code

    • Look for any transactions labeled with:

      • Code A (Basis reported to IRS - Short Term)

      • Code B (Basis not reported to IRS - Short Term)

      • Code C (Short-term transactions not reported on 1099-B)

    • Check the purchase date (Date Acquired) and sale date (Date Sold) for each transaction.

  4. Determine Holding Period

    • If the security was held for more than one year, it should be classified as long-term.

    • Long-term transactions should be coded as:

      • Code D (Basis reported to IRS - Long Term)

      • Code E (Basis not reported to IRS - Long Term)

      • Code F (Long-term transactions not reported on 1099-B)

  5. Correct the Entry

    • If the purchase date is more than one year before the sale date, change the code to D, E, or F for long-term treatment.

    • If the transaction is truly short-term, verify that the purchase date is within the last calendar year.

  6. Validate and Resubmit

    • Run Diagnostics in TaxWise to check for errors.

    • Save and resubmit the return once corrected.


Key Takeaways

Short-term gains (held ≤ 1 year) should be coded as A, B, or C.
Long-term gains (held > 1 year) should be coded as D, E, or F.
Ensure the correct purchase and sale dates match the proper holding period.
Run diagnostics before submitting the return.

By following these steps, the error will be resolved, and the return can be processed correctly! 🚀
