should i claim 0 or 1 on my withholding 
electing 0 as an allowance on the w 4 for tax withholding will result in the largest amount being withheld for your filing status claiming one allowance will reduce what is withheld for taxes but may still be sufficient for what is owed claiming 0 is preferred by people who can be claimed as dependents by others and by people who have more than one source of income
