Users of the Adobe Acrobat Reader: Adobe® Reader XI are also now able to save data that is entered on a fillable form. This means any .PDF fillable form, including those available on the Oklahoma Tax Commission website, can now be saved to a user’s computer. This allows for a .PDF form to be completed in more than one sitting/session since data can be saved after each use. The Adobe Reader XI is free to download by all users (like previous versions of Adobe Reader) and can be downloaded from: www.adobe.com/products/reader.html.
