The gift tax annual exclusion is $14,000 per year. As this guy states, you can effectively double it to $28,000 if your mom is living. Also, if you are married, you can double it further (e.g., to $56,000), as you and your spouse can split gifts for gift tax purposes. If you go over the annual amount, don't worry about it. Your lifetime gift/estate tax exemption is currently $5,490,000, and you have to burn through that before you would ever pay gift tax. (Also, you do not have to elect anything to use it.) Last, gifts are not taxable income, so there is no real need to pay it "under table."
