Only one spouse needs to qualify
Under IRC Section 469(c)(7), when a married couple files jointly, the REPS qualification tests (the 750-hour test and the more-than-half test) are applied to each spouse individually. If either spouse independently meets both tests, the couple qualifies. You do not combine the hours of both spouses to reach the thresholds.
This is the most common REPS strategy for married couples: one spouse dedicates the majority of their time to managing the rental portfolio while the other maintains a W-2 job. The qualifying spouse's REPS status then allows the couple's jointly-owned rental losses to be treated as non-passive on the joint return.
This structure is especially effective when combined with strategies like cost segregation studies that generate large paper losses in the early years of ownership. The W-2 spouse's income can be offset by the rental losses made possible through the other spouse's REPS qualification.
