Filing Tips & Audit Alerts
- ✓Inherited real estate and stocks receive a 'Step-Up in Basis' to fair market value at date of death, minimizing future capital gains tax.
- ✓Even if the estate is non-taxable, filing Form 706 timely is required to elect DSUE portability to transfer unused exemption to the surviving spouse.
- ✓Cross-verify prior Form 709 gift tax returns to accurately calculate remaining unified credit limits and prevent IRS audit rejections.
