You or your husband are not required to file any forms with the IRS. Gifts of a present interest (which cash is) between spouses can be unlimited. However, any gifts between nonspouses would require the transferor to file a gift tax return (IRS Form 709) if the gift exceeded $12,000.
Congratulations on your marriage.
No gift tax return (Form 709) is needed if you and your husband were USA citizens or resident aliens at the time of the gift. There is an unlimited allowable amount of "present interest" (not future interest such as capital gain, etc) for spouses.
Be aware that the regular 12000 per year limit for gifts does still stand if either of you were nonresident aliens at the time of the gift. Form 709 would need to be filed to report 108000 as a gift (120000 - 12000 = 108000) by him if this is your situation.
