I've seen the same issue when on using sql scripts on different machines. Tab settings often differ locally and that's why I would rather use spaces instead of tabs. I never liked using tabs across local machines and websites, but trouble is that so many tools use tabs.
You can easily replace a tab with a certain amount of spaces with Find and Replace in SSMS at least.
