About fillable forms

Help with fillable forms

As with all CRA forms, you are responsible for the completeness and accuracy of all the data that you provide on fillable forms.

Software for using fillable forms

CRA PDF forms have been tested for compatibility with Adobe Reader 9 and higher. These forms may also be opened with other PDF viewers such as Foxit Reader, PDF-XChange Viewer, and Nuance PDF Reader; however, some form features may not be fully supported. These PDF viewers can be obtained for free from the vendors’ Web sites.

Google Chrome and Apple Safari come with built-in PDF viewers that are enabled by default to open PDF files directly in the browser window. If you are using one of these browsers, you must first download the CRA form and then open it using a compatible PDF viewer.

Completing fillable forms

In addition to the information provided here, you can access the online guides for your PDF viewer software. For example, if you have Adobe Reader, click Reader, Help, Adobe Reader Help.

Moving within a form

  • Enter the appropriate data in each box or field. By default, all fields where you can enter or select information are highlighted.
  • To move from one field to the next, press the "Tab" key or use the cursor.

Multi-part forms

Multi-part forms consist of an original form (the top copy) plus one or more copies that are automatically created once the original form is completed (for example, an information slip).When the same information is needed on more than one part or copy of a form, enter the information only once, in the first part of the form. Note: In some cases, copies may only appear after the form is printed.

Forms that perform calculations

The CRA Web site includes some fillable forms that perform calculations.

These calculations are based on the amounts you enter. For example, when you enter data in two fields that are to be added together, the form automatically calculates the total and inserts it in the correct third field.

You are responsible for the completeness and accuracy of any information submitted on a fillable form that performs calculations. Be sure to double-check all the data that you enter!

Fields with a limited number or type of characters

  • Some fields limit the maximum number of characters that you can enter. You may also be restricted to entering certain types of characters only, such as numeric or alphabetic.
  • For example, you can have a maximum of nine characters in the field where you enter a social insurance number and the characters must be numeric.

Specific fields

  • Dates: Unless otherwise specified, enter all dates in the format yyyymmdd.  For example, for February 3, 2011, enter 20110203. The slash characters separating the year, month, and day will be inserted automatically.
  • Dollar amounts: When entering dollar amounts that include cents, you must enter the decimal point.
    • If you do not enter the decimal point, the system will assume that the amount you entered is all in dollars and will automatically insert a decimal point after the final.
  • Signatures: If you are using a fillable form that requires a signature, after you have completed the form, print it and sign it by hand.
    • The system will not let you enter anything online in the signature field.

Special links

  • When using a fillable form, you can click on these buttons as needed:
    • Help: Accesses the help file for the form you are using.
    • Publications: For some forms, enables you to link to a corresponding publication, for example, a guide or another form. The link is either a blue box surrounding the publication name, or a solid line under the name.
    • Instructions: Displays instructions specific to that form, for example, the instructions on the back of a printed form.
      • Note: Not all CRA forms include these extra instructions.
    • Information icon (lower-case “i”) or light bulb: Clicking the icon beside a field or section of a form displays a special message or instructions about that field or section.
    • Clear Data or Restore : Erases all the data that you entered on a fillable form and so that you can start over.

Downloading blank forms

You can download a blank fillable form for future use:

  • For example, if you are using Microsoft Internet Explorer, do the following:
  • On the CRA Web page that you are viewing, right-click the hyperlinked file name, click "Save Target As," and type a name for the file.
  • Save the form in the directory of your choice, and then use your PDF viewer to access it.

Saving completed forms

For example, if you are using Adobe Reader, from the Reader menu bar, click “File, Save as.” You can save the file in the default directory, or browse and select a different directory.
