The 60-day and 45-day figures come from Tex. Ins. Code Sec. 1501.216 (texas.public.law/statutes/tex._ins._code_section_1501.216). That section covers Texas small employers, defined as 2 to 50 employees. Above 50 employees you are not covered by it, so confirm your notice terms with your carrier or broker. The 8, 12 and 15 percent figures are what carriers in this market tend to propose, not filed or approved Texas rates. This page organises dates and arithmetic only. It is not insurance advice.
