During your lifetime and as long as you are the trustee and managing the trust all of the items which you place into the trust will be taxed using your social security number, therefore you will not see any change at all tax wise. All income will be reported on your normal income tax return as it was before you set up the trust. Also note the trust will not have an effect on estate or gift taxes as when you pass away any assets which are in the trust will be considered in your taxable estate for estate tax purposes. However proper planning with your Revocable Living Trust will allow you to minimize your estate taxes especially between a married couple taking advantage of the exemptions allowed by law.
