<prompt> Human: I got into the habit of paying extra taxes each pay period to ensure a big return every year. I know I dont receive any interest or anything, and I know it would make more sense to out it into a savings account, but it guarantees a nice return every year to go on vacation or something similar. Anyway, using easy numbers...say I pay 5000 a year and get back 2500. If Ive already paid 2500 this year, can I just stop paying for the rest of the year? Any advice would be appreciated. Edit - My numbers were off...Ive fixed them I think  <response>: Yes.Just remember to change it back at the start of next year.
