What the Evidence Shows
The claim that Los Angeles contributes almost $20 billion in taxes and that this amount exceeds the total tax contributions of all but four U.S. States involves two key components: the total tax contribution figure for Los Angeles city, and a comparative ranking against states. Available data sources provide extensive information on state-level tax contributions to the federal government, with California as a whole contributing hundreds of billions annually (e.g., $83 billion more in federal taxes than it receives in federal support), but do not break down tax contributions at the city level in a comparable manner.usafacts.orgusafacts.orgWhich states contribute the most and least to federal revenue?

The Los Angeles Office of Finance details city tax collection for municipal purposes but does not report federal tax contributions by residents or businesses within the city.finance.lacity.govfinance.lacity.govTax Information Booklet Furthermore, no credible source was found that ranks Los Angeles city’s tax payments relative to entire states. Given that states encompass multiple cities and counties, it is unlikely that a single city’s tax payments would surpass those of most states except the largest contributors.
Without direct data or official reports quantifying Los Angeles city’s federal tax contributions and comparing them to states, this claim cannot be verified. It may stem from a misunderstanding or conflation of state-level data with city-level figures.
Therefore, the claim remains unverifiable based on currently available evidence.
