Honest Expenditure Limitation Program Act of 2010 or HELP Act - Amends the Congressional Budget Act of 1974 to make it out of order in the House of Representatives or the Senate to consider any bill, joint resolution, amendment, or conference report that includes any provision that would exceed specified non-security discretionary spending limits for FY2011-FY2020.
Limits non-security discretionary spending limits for FY2011-FY2015 to the level provided in FY2010, but reduced each year on a pro rata basis so that the level for FY2015 does not exceed the level for FY2008. Limits the spending levels for FY2016-FY2020 to the FY2015 spending level.
Defines "non-security discretionary spending" as discretionary spending other than spending for the Department of Defense (DOD), homeland security activities, intelligence-related activities within the Department of State, the Department of Veterans Affairs (VA), and national security related activities in the Department of Energy (DOE).
