How can I make the background transparent while saving the file as GIF

Don't use GIF. For logos, the PNG format does everything GIF does, better.

Then for clean and crisp edges without jaggies or white halo:

• Layer>Transparency>Add alpha channel (disabled if already done)
  
• Start the wand tool, and select the background (keep the standard Threshold). If there are isolated bits (inside of letters such as O), shift-click them to add them to the selection.
  
• Select>Grow by 2 pixesl
  
• Colors>Color to alpha and remove the white
  

File>Export as PNG
