This is our main tax information forum which deals with topics concerning Canadians living and working in the U.S., U.S. citizens contemplating working in Canada, and all aspects of Canadian and U.S. income tax and related adminstrative issues.
Thte fact that you don't know would lead me to believe that your 401(k) account hasn't been set up yet (which is normal for new hires), so you won't be making any contrib on your Oct 31 pay stub.
Hope you can double up in November, especially if you can Roth401(k).
nelsona non grata. Non pro. Please Search previous posts, no situation is unique as you might think. Happy Browsing
