First off, in regards to GE, you're only taxed on money you earn in the country. Second, if you earned money last year and earned less (or lost) this year, you've technically overpaid and your tax burden will be significantly lower.
Second, in 2010, Google paid $2.29 billion in taxes on $10.8 billion in pretax income. 21% is slightly higher than 2.4%.
