How do I correct a return if I misunderstood the rules for a large family gift?

When preparing the return, special rules can apply to certain direct payments, spouses, noncitizens, trusts, and split gifts. A related point is to separate what happened before death, after death, and after distribution because those dates can move income between different returns. For the relevant filing, the donor may have a Form 709 filing requirement when gifts to a person exceed the annual exclusion, even when no gift tax is immediately payable because the donor still has lifetime exclusion available. Retain the records that support the reported amount and the relevant dates, then have a CPA, enrolled agent, or tax attorney verify the taxpayer, form, basis, and filing deadline.
