Delaware Seniors: Make sure to check your eligibility for BOTH senior tax credits. Many seniors may only be getting the "Senior School Property Tax Credit" but there is also a “ELDERLY” Exemptions for Residents Age 65+ Credit" and it's pretty confusing as the income level EXCLUDES social security.

Both forms can be found on the tax relief page with direct links to the county website:
