We apply either State plan income disregards or SSI income exclusions, whichever of them results in the lower amount of countable income. But we never use a combination of State disregards and SSI exclusions.

If applying either State plan disregards or SSI exclusions permits eligibility for a month, the individual is eligible.

A computation using Federal exclusions and a computation using State disregards are both needed. In determining payment, we choose the method that yields the lower amount of countable income.

Different computations may be used to determine eligibility and payment. For example, we might establish eligibility using State plan disregards, but then compute payment using the SSI exclusions because they result in less countable income (and, thus, a larger SSI benefit).

Blind countable income (BCI) is the result of applying State plan disregards to a converted blind recipient's gross monthly income.

Countable income under Federal rules (CI/FR) is the result of applying SSI exclusions to gross monthly income. It is the sum of Federal countable income (FCI) and the value of the one-third reduction (VTR), if applicable.

Countable income is the lesser of BCI and CI/FR.

Calculate BCI for each month and project a continuing rate. See SI 01210.500 ff. for instructions.

Input to the Supplemental Security Record (SSR) the gross monthly income and any special exclusions that apply, such as blind work expenses (SI 00820.535).

In the same transmission, input BCI for each month as type K unearned income.

If the case is in force due, determine eligibility and payment amount for each month manually. This determination, as explained in A.2. and 3. above, requires a monthly comparison of the results of using the State plan disregards and the SSI exclusions. (Since April 1982, retrospective monthly accounting applies to computations using either State plan disregards or SSI exclusions.) Force the system to release any amounts due, per SM 01701.010ff.
