Your tax calculator is off. You say my taxes are $105 more than I get, on same income, using Worksheet, 1040 Instr, page 40). H&R Block's online calculator agrees w/me.

Ok ... please review the Qualifying Dividends & Cap Gain worksheet in the return to see how the tax is being calculated ...  and to see where your calculations are different ...  

You can peek at only  the Federal form 1040 and the summary of the state info by going here:

2)  then select "Tools"
3) then select "View Tax Summary" from the pop-up
4) then back to the left-side and "Preview 1040"
