You only be hit by a tax bill if you chose to exercise the option, which only make sense if the stock is worth more than the strike. If you are "given" something that is worth more than $1, the IRS will want a piece of it.
If you worked at a startup (not a small business), the most likely outcomes after 4 years is either 1) Company went bust, 2) Company grew.
The option protects you from the not having to pay anything if scenario #1 happens. If scenario #2 happens, then you should be happy: you have an option to pay X for something that is usually worth multiples of X after 4 years.
I actually think the IRS is being nice not to tax the at-the-money option grant. They essentially assume zero time value, which would be quite high for a startup given the high volatility and the potentially long term for the option.
