How the PMV Math Works
The PMV equals one third of the federal SSI benefit rate plus the $20 general income exclusion. For 2026, with a federal benefit rate of about $967 per month, the PMV calculation is:
- One third of $967 = $322.33
- Plus $20 = $342.33
- SSI reduction (after the $20 exclusion is applied to the unearned income) = roughly $322
That means the worst-case impact of in-kind support and maintenance on an SSI check is about $322 per month, no matter how expensive the rent or groceries actually are. A beneficiary who would otherwise receive $967 ends up with roughly $645.
Rebutting the Presumption
The PMV is a presumption, not a hard rule. If the actual current market value of the food or shelter help is less than the PMV, the recipient or their representative can submit evidence (a fair-market rental analysis, utility bills, a roommate-share computation) to lower the SSI reduction. This is most useful when a beneficiary lives in a low-cost shared household.
Why the PMV Matters for SNT Planning
For special needs trust trustees, the PMV is the worst-case math when deciding whether the trust should pay rent or utilities directly. If the benefit to the beneficiary clearly exceeds the $322 SSI reduction, paying for shelter from the SNT can still make sense. If not, routing the same help through an ABLE account avoids the reduction entirely.
