Income Eligibility Tests

Test	Threshold	Source
Gross Income	< 30% FPL	K.S.A. 39-709
Countable Income	< Payment Standard	KEESM 7110
Resource Limit	≤ $3,000	KEESM 5000

Income Deductions & Exemptions

Per KEESM 7200, deductions are applied in order:

Order	Deduction	Amount	Source
1	Work Expense	$90/employed person	KEESM 7200
2	Earned Income Disregard	60% of remainder	K.A.R. 30-4-111, KEESM Memo 2008-0326
3	Dependent Care	Actual, unreimbursed (NO CAP)	KEESM 7224

Note on 60% Disregard: Per K.A.R. 30-4-111(b)(2), this disregard does NOT apply when initially establishing TANF eligibility unless the person received TANF in one of the four preceding months. PolicyEngine applies this disregard to all applicants since benefit history cannot be tracked.

Family Size	Payment Standard
1	$241
2	$326
3	$403
4	$471

Benefit Calculation

Countable Income = Countable Earned + Unearned Income
