To expand crop insurance available to beginning farmers and ranchers, and for other purposes.

Whole Farm Crop Insurance Improvement Act of 2018 This bill modifies requirements for the Department of Agriculture (USDA) Whole-Farm Revenue Protection (WFRP) crop insurance policy, which covers all commodities on a farm under a single policy. The bill requires USDA to: expand coverage for beginning farmers under the Non-Insured Crop Disaster Assistance Program to allow the farmers to develop the revenue history necessary to qualify for WFRP; allow insurance providers to use alternative compensation structures based on the time necessary to write and administer the plans; ensure that that all producers, including producers with expected revenue from an operation that is greater than 35% of the revenue for the previous year, are able to obtain coverage; and reduce paperwork requirements for the program.
