Rob and Heidi (married filing joint) expect to pay $20,000 in tithing and $8,000 in state and local taxes each year for the next few years. If they have a 24% marginal tax rate, calculate how much they would save over the next two years if they use “bunching” (assume a standard deduction in 2019 of $24,400).
