Actually I was mistaken - the partial inclusion of Social Security benefits applies to gross income, not AGI. So we'd additionally have to make all Social Security benefits taxable. Here's how we can do that:
reform = Reform.from_dict({
"gov.irs.social_security.taxability.rate.additional": {
"2024-01-01.2100-12-31": 1
},
"gov.irs.social_security.taxability.rate.base": {
"2024-01-01.2100-12-31": 1
},
"gov.irs.social_security.taxability.threshold.base.main.HEAD_OF_HOUSEHOLD": {
"2024-01-01.2100-12-31": 0
},
"gov.irs.social_security.taxability.threshold.base.main.JOINT": {
"2024-01-01.2100-12-31": 0
},
"gov.irs.social_security.taxability.threshold.base.main.SEPARATE": {
"2024-01-01.2100-12-31": 0
},
"gov.irs.social_security.taxability.threshold.base.main.SINGLE": {
"2024-01-01.2100-12-31": 0
},
"gov.irs.social_security.taxability.threshold.base.main.SURVIVING_SPOUSE": {
"2024-01-01.2100-12-31": 0
}
}, country_id="us")
In isolation, this reform raises $67 billion in 2024.
Since Social Security benefits are counted in AGI in a way that makes a flat tax on AGI not a true flat tax (based on other income)
