The valuation date is the important date in this instance. Therefore if your brother is considered a farmer at this date there is the opportunity for "tax planning". This would involve transferring his non agricultural assets to his wife in advance of the valuation date. These transfers to a spouse are exempt from all taxes. If he goes ahead and does that he should be careful not to put an arrangement in place for the return of the non agricultural assets from his wife as this may be regarded as "tax avoidance" and a clawback of CAT could be triggered via S811 TCA 97.
The important thing would be for him to transfer the non agricultural assets to his wife unconditionally and at some point down the line put them back in joint names.
