Hurricanes Florence and Michael and California Wildfire Tax Relief Act This bill provides for tax relief for individuals in areas affected by Hurricanes Florence and Michael and the California wildfires. Specifically, it allows tax-free distributions from tax-preferred pension plans for disaster-related expenses, increases the limit on allowable loans from pension plans, allows employers in disaster areas a tax credit to assist in retaining employees affected by disasters, suspends the limitation on the tax deduction for charitable contributions for disaster relief, allows nonitemizing taxpayers to claim personal casualty losses, and allows the use of earned income for the preceding year for claiming the earning income and child tax credits.
