Common mistakes
- Using this schedule for excluded foreign dividends: The form says foreign dividends paid by partially included members of a water’s-edge combined report cannot be computed on this schedule.
- Overlooking the Part III ownership requirement: Ownership of the dividend payer must be at least 80%.
- Transferring Part I without checking Part III: The direction to transfer Part I directly to Form 100S, Side 2, line 9, applies only if there is no entry in Part III. Part III directs you to combine its deductible dividend total with the Part I elimination amount.
- Leaving the schedule unattached: The form directs you to attach Schedule H to Form 100S and add sheets if necessary.
