ACA ESRP Exposure Calculator

Computes proposed IRC 4980H(a) ("no offer to 95% of full-time employees") and 4980H(b) ("unaffordable / not minimum value") Employer Shared Responsibility Payment exposure from supplied full-time-employee counts, minimum-essential-coverage offer counts, and PTC-triggering employee counts, using the version-pinned 2026 per-employee penalty amounts ($3,340 (a) / $5,010 (b) annual, IRS Rev. Proc. 2025-26). This is exposure math, not a determination that an assessment is owed.

Ask your agent

Copy this paragraph into Claude, OpenClaw, or any MCP-aware agent to run this exact tool, with this sample, and verify the artifact.

Run the AINumbers MCP tool `compute_esrp_exposure`. Task: Compute proposed IRC 4980H(a)/(b) Employer Shared Responsibility Payment exposure from supplied full-time-employee, MEC-offer, and PTC-triggering employee counts, using the version-pinned 2026 per-employee penalty amounts.
Call it with arguments: {"policy_parameters":{"tax_year":"2026","fulltime_count":200,"offered_mec_count":150,"ptc_employee_count":5}}
Verify before trusting: call `verify_execution_hash` on mcp.ainumbers.co (https://mcp.ainumbers.co/mcp) with the parameter `claimed_hash` set to the returned `execution_hash`, passing the full artifact the run returned (the object containing `policy_parameters` + `output_payload` + `execution_hash`; equivalently `policy_parameters` + `output_payload` with `claimed_hash`), not the bare hash string.
Return the ledger link https://ledger.ainumbers.co/ so a human can re-verify without contacting us.
