Always.... possible complications
Well...one thing to be careful of, is that if it is a W-2 job, you can only have income taxes withheld that are only the specific amount you would normally get AFTER SS and Medicare taxes are first withheld. So is the $50, before, or after SS and Medicare withholding (and will it always be that $$ amount).
So you might need to select some lower even $$ amount...like maybe $30 or $40...and be resigned to collecting the difference between the $50 gross and the (SS +Medicare + income tax) withholding. The W-4 only can only specify the income tax withholding part.
....also you need to ask the employer if the state requires withholding too. Sometimes certain states will allow a W-2 provider to not withhold any state income taxes, other states may require a certain % no matter what the level of $$ being payed to a W-2. (though its true I don't know of specific states that require a % in all instances )
