It depends. As you know the key is to have Column A exactly as your original return so if for some reason they have changed then you should modify them to match. Once this is accomplished the other columns should be correct.
- Column A. This column shows the numbers previously reported on your tax return. Use the copy of your tax return to complete this column.
- Column B. This column shows how the amounts from your original return need to increase or decrease. For example, if you're amending your gross income to include $50 of interest income missing from your previously filed tax return, you would enter $50 on line 1, column B.
- Column C. This column shows the correct amount. Just add the amounts from column A and column B and enter the result here.
Double check your original refund or balance due (lines 18 and 16) and your amended return should be ready to file.
