State Tax Data Sources
These state tax data sources and methods explain where every States News Journal figure comes from and how we keep it current. We list the source next to each table so you can verify it.
Primary sources we use
- State revenue departments: official rates, forms, deadlines and refund status tools.
- State labor agencies and the US Department of Labor: minimum wage rules and effective dates.
- State statutes and legislative sites: the legal text behind a rate or wage change.
- Tax Foundation: state-by-state summaries of sales tax and individual income tax rates, used when no single official source covers all states.
How we choose between sources
We use the official agency or statute first. If a secondary source differs from the agency, we follow the agency and note the difference when it matters to readers.
What the numbers mean
Sales tax figures show the state rate and, where noted, local averages. Income tax figures show the top marginal rate for wage income. Minimum wage figures show the general state rate for adult workers. Some cities and counties set higher wages, and special rules apply to tipped and small-business workers.
How we date and refresh data
Each table shows its last check date. We refresh figures on a regular schedule and after major rate or law changes. See our editorial policy for the full process.
