Yes.

When you pay 1 life and exile a blue card to Force of Will, you aren't bypassing the cost, you're paying an alternative cost. The new cost to cast the spell is "pay 1 life and exile a blue card from your hand." Tax Collector's effect will add a mana to that total cost you pay.

The difference between this effect and Trinisphere is that Trinisphere will add whatever amount of mana increase that brings the cost up to 3. It will increase the cost to cast Force of Will to 1 life, exiling a blue card, and paying {3} because the casting cost being paid didn't have any mana. On the other hand, if Force of Will were cast for its mana cost, Trinisphere would do nothing since it already costs at least {3}, but Tax Collector would still increase the cost from {3}{U}{U} to {4}{U}{U}.

Tax Collector also isn't symmetrical, while Trinisphere is, so in the second case you'd have to pay {2}{U} to cast that Opt.

If I cast Tax Collector and elect the mode to make my opponent's spells cost an additional generic mana, if I then cast a Opt and my opponent responds with a Force of Will, would they have to pay the additional {1}? What's the difference between this effect and Trinisphere?
