Use a separate 1040X for each year if you are amending more than one tax return, and mail each in a separate envelope to the IRS processing center for your state. The address for the centers is listed in the 1040X instructions.
If the changes involve another schedule or form, attach it to the 1040X. For instance, if you are filing a 1040X because you have a qualifying child and now want to claim Earned Income Tax Credit, you must complete and attach a Schedule EIC to the amended return. You must file Form 1040X to claim a refund within three years from the date of filing of your original return, or within two years from the date you paid the tax, whichever is later.
If your gift to any one person is valued at more than $12,000, you will have to report the total gift to the Internal Revenue Service. You may even have to pay tax on it.
However, the person who receives your gift does not have to report the gift to the IRS or pay gift or income tax on its value. A gift is that which you make when you give property (including money) or the use of or income from property, without expecting to receive something of equal value in return. So if you happen to sell something at less than its value, or make an interest-free or reduced-interest loan, you could be making a gift.
There are some exceptions, however. The following do not count as gifts against the annual limit:
Gifts to your spouse
Tuition or medical expenses paid directly by you to an educational or medical institution for someone’s benefit
Gifts to political organizations
Gifts to charities
Also, if you are married, both you and your spouse can give separate gifts of up to the annual limit to the same person without making it a taxable gift.
A mismatch between a name on the tax return and the Social Security Number (SSN) could unexpectedly increase a tax bill or reduce a refund. So you should make sure that the name on your tax return matches the name registered with the Social Security Administration (SSA).
You will have to inform the SSA of a name change by filing Form SS-5 at your local SSA office. Take or mail your completed application and documents to your local Social Security office or your local Social Security Card Center. Usually it takes two weeks to have the change verified. The form is available on www.ssa.gov and at local offices. Local office addresses are available on the SSA website.
