Cal. Civ. Code § 6.05

(1) The Computation of Net Household Income. Rent is a percentage of net Household income,
           as provided in 760 CMR 6.04(1), (25%, 27%, 30%, or 32% except as provided in
           760 CMR 6.04(1)(c) and (d)). In order to determine net Household income, the LHA shall first
           determine gross Household income. Gross Household income includes the income items set out
           in 760 CMR 6.05(2) and excludes the non income items set out in 760 CMR 6.05(3). The
           deductions set out in 760 CMR 6.05(4) are deducted from gross Household income so computed,
           and the result is net Household income.

           (2) Inclusions in Gross Household Income. Gross Household income shall be the total of the
           following items:
               (a) The full amount, before any payroll deductions, of wages and salaries, overtime pay,
               commissions, fees, tips and bonuses, and other compensation for personal services.
               (b) Income from the operation of a business or profession by each self-employed Household
               Member after deduction for the ordinary and necessary expenses of the business or
               profession. The deductible expenses of the business or profession shall not exceed 85% of
               the gross receipts of the business or profession. Deductible expenses of the business or
               profession shall not include rent or Utilities paid for the Tenant's unit if the business or
               profession is located in the Tenant's unit.
               (c) Income of any kind from real or personal property including rent, dividends, and interest.
               Amortization of capital indebtedness and depreciation shall not be deducted in computing
               net income. Any realization of taxable capital gain on sale or transfer of an investment or
               other real or personal property shall be included in income. If the Household has marketable
               real or personal property with a fair market value exceeding $25,000 (excluding any
               automobile used as the primary means of transportation by one or more Household
               Members), gross Household income shall include the higher of actual income derived from
               any such property or a percentage of the value of such property. This percentage shall be one
               percent or as otherwise determined from time to time by EOHLC and posted on EOHLC's
               website.
               (d) Periodic payments received from social security, annuities, retirement funds, and
               pensions, individual retirement accounts, and other similar types of periodic payments of
               retirement benefits, excluding non taxable amounts which constitute return of capital and are
               specifically identified as such by payer.
               (e) Payments in lieu of earnings, such as unemployment compensation; Supplemental
               Security Income (SSI); Social Security Disability Income (SSDI); and benefits in lieu of
               earnings under disability insurance, health and accident insurance or workers' compensation.
               An unallocated lump sum settlement or similar payment all or partly on account of lost wages
               resulting from an injury shall be equitably allocated to reflect a monthly payment on account
               of lost wages for the period during which the recipient is likely to be disabled from the injury
               and the recipient will be deemed to receive such a monthly payment each month during the
               continuance of his or her disability until the allocated funds are deemed exhausted. Payments
               from the government, subsequently reimbursed to the government, are not to be included as
               income.

(f) Contributions or gifts received from non Household Members that are more than $5,000
              in the aggregate in a 12-month period, provided that only the amount of the contributions or
              gifts that exceeds $5,000 in the aggregate shall be included.
              (g) Regular payments of public assistance, excluding food stamps.
              (h) Payments received for the support of a Household Member, such as payments for child
              support, foster care, social security, or public assistance, including payments nominally made
              to a Household Member for his or her support but controlled for his or her benefit by another
              Household Member who is responsible for his or her support.
              (i) Lottery winnings, gambling winnings and similar receipts.
              (j) Receipts of principal and income from the trustee of a trust, and receipts of income from

               in the aggregate in a 12-month period.
               (b) Amounts (including lump sums), which are specifically received for the cost of medical
               care, or which are made to compensate for personal injury or damage to or loss of property
               under health, accident or liability insurance, worker's compensation, judgments or

               amounts paid by the United States Government to a veteran for use in paying tuition, fees,
               or the cost of books, to the extent that such payments are so used.
               (d) The special pay to a member of the armed forces on account of service in a war zone.
               (e) Relocation payments made pursuant to state or federal law.
               (f) Payments received from the Social Security Administration program known as the Plan

               accredited educational or vocational institution. The amount of stipends to volunteers that
               shall be excluded may not exceed the total amount which would have been earned by a
               person working 20 hours per week at the minimum wage specified in M.G.L. c. 151, § 1.
               (i) The increased amount of income earned from employment by one or more Household
               Members if the increase in earned income otherwise would result in a rent increase provided
               that:
                   1. the Household's income has been derived, at least in part, from Transitional Aid to
                   Families with Dependent Children (TAFDC), Emergency Assistance to the Elderly,
                   Disabled and Children Program (EAEDC), Supplemental Security Income (SSI), Social
                   Security Disability Income (SSDI) or successor program for each of the previous 12
                   months;
                   2. the Household's increased earned income has been accompanied by a decrease in the
                   amount of TAFDC, EAEDC, SSI, SSDI or public assistance from a successor program;
                   and
                   3. at the commencement of this exclusion the recipient of such public assistance would
                   have remained eligible for such assistance if the income had not been earned. This
                   earned income exclusion shall be in effect for one continuous 12-month period,
                   regardless of any changes or gaps in employment during that period. This exclusion may
                   be exercised by the Tenant when a Household Member has procured either full or part

              as transportation, program fees, books, or child care (during training). This exclusion shall
              apply to wages received through programs for training for employment, such as wages from
              on the job training, or apprenticeship, for a period not to exceed two years. This amount of
              the exclusion shall be limited to the amount of wages received in such programs for working
              up to 37.5 hours per week that do not exceed 1½ times the minimum wage specified in
              M.G.L. c. 151, §1.

                  Disability Veterans Compensation in excess of $1,800 per year, such LHA shall continue
                  to exclude all of such amounts for those Tenants who were previously granted the
                  exclusion.
              (o) A return of capital on sale or transfer of an investment or of other real or personal
