From what I can find online[1,2], for a dual-income family earning 250k CAD/ 250k USD, tax in BC Canada[1,2] is 33% Federal + 16.80 % State = 49.8%. For California it is 24% Federal + 9.3% State = 33.3%. Is there a big difference in other taxes (like Payroll/Social Security) between California and BC that makes the overall marginal tax same?
