How do I determine my tax bracket based on T4 slip ?

[g27v5]

Ok,so I am in Quebec. Quebec has ridiculously high tax rate which is 16% for $41935 or less annually.
This year my income will be around $43000 so I am going to purchase RRSP to drop my income below $41935...

Now it gets down my questions: How do I determine what is my net income ? I think it is just number 14 (employment income line 101) ? I add the numbers from line 101 together and they will be my net income ? And we not gonna talk about capital gains from investments and stuff because I have none. Regardless of all other stuff, is employment income = line 101 ? Or there are more other stuff I need to add up?
Thank you

You can go here and manually fill in a copy to see where your net income ends up.
