I have done a quick check to make sure the employee will not be paid more than the basic exemption and it does appear to be that way. I have also entered 9999999 in the claim amounts. I ran paycheques this week and it still calculated just under $2 for tax but I changed to manual calculation and took out the tax. I think the best thing to do is prepare the pay cheque for this employee last that way I wont make a mistake on the other employees cheques if I forget to toggle back to automatic calculation. I found that doing his cheque last also helps me to remember to change back to automatic calculation because it is different from the rest.
Thank you all for taking the time to help me work through this it has been a great help and much appreciated.
