Should I be claiming more than 1 exemption?
It's not possible to determine whether you can "expect a refund" or whether you are claiming the right number of exemptions from the information given.   If your wife were not working and you did not do independent contracting, then the answer would be much simpler.  However, in this case, we must also factor in how much your contracting brings in (since you must pay income tax on that, as well as Medicare and, probably, Social Security), whether you are filing jointly or separately, and your wife's income from her business.   There are also other factors such as whether you'll be claiming certain child care expenses, and certain tax credits which may phase out depending on your income.   If you can accurately estimate your total household income for the year, and separate that into income from wages, contracting, and your wife's business, as well as your expenses for things like state and local income and property taxes, then you can make a very reasonable estimate about your total tax burden (including the self-employment taxes on your non-wage income) and then determine whether you are having enough tax withheld from your paycheck.  Some people may find that they should have additional tax withheld to compensate for these expenses (see IRS W-4 Line #6).
