Eek! Taxes!

I got my municipal tax bill in the mail today, and all I can say is "Yikes!". Holy bat bill. I knew I made a lot of money last year, but come on. I didn't make twice as much, and yet my tax bill doubled. Clearly I need to do some research on the free programs and discounts my ward (city area) offers, because I should be taking advantage of them! Perhaps I should research at what point the tax rate doubles too - and make sure I don't go over that much income this year!
