How to fill in the forms
As you complete your form, follow these guidelines to avoid processing delays:
Use black ink only (no red or other color ink or pencils) to print or type (if you are using a fill-in form) all entries.
If you are entering a loss (an amount less than zero), place a minus sign immediately to the left of the loss amount. Do not use brackets or parentheses.
Mark an X to fill in boxes as appropriate. Do not use a check mark. Keep your X s and numerals inside the boxes.
Do not write in dollar signs or commas when you enter amounts or numbers.
