US state individual income-tax burden intelligence (2026)
Complete 51-jurisdiction panel (50 states + DC) of 2026 state individual income-tax structures, transcribed 2026-10-01 from the Tax Foundation's '2026 State Income Tax Rates and Brackets' table (single filer, as of January 1, 2026): single-filer brackets, standard deduction, structure (none / flat / graduated / capital-gains-only for WA), and computed effective tax rates at $50k/$100k/$250k wage income (single filer, standard deduction applied; Utah's $966 credit modeled), marginal rate at $100k taxable, progressivity spread, and documented burden tiers. West Virginia corrected to the SB 392 rates (2.11%-4.58%, retroactive 2026-01-01). Tax rates and brackets are facts (Feist v. Rural) compiled from state statutes -> commercial_use=yes with attribution to the Tax Foundation. Caveats: single filer only; wage income only; local income taxes excluded; personal-exemption credits and AL's federal-tax deduction not modeled. Join on geo_code (ISO 3166-2) or state_abbr for disposable-income demand features, subscription pricing-power signals, and tax-burden territory scoring.

|---|---|---|
| geo_code | string | ISO 3166-2 jurisdiction code (US-AL .. US-WY, US-DC); primary join key. |
| country_code | string | ISO alpha-3 country code (USA). |
| state_abbr | string | USPS postal abbreviation. |
| state_name | string | Full state / district name. |
| has_wage_income_tax | integer | 1 if the state taxes wage income (42 jurisdictions incl. DC); 0 for the 8 no-income-tax states + WA (capital-gains-only). |
| tax_structure | string | Tax Foundation classification: none, flat, graduated, or capital-gains-only (WA). |
| n_brackets | integer | Number of taxed single-filer brackets (0 for no-tax states). |
| bottom_rate_pct | float | Lowest nonzero single-filer rate, %. |
| top_marginal_rate_pct | float | Top single-filer marginal rate, % (0.0 where no wage tax). |
| top_bracket_threshold_single | float | Taxable income (USD) at which the top rate kicks in; null for no-tax states. |
| std_deduction_single | float | Single-filer standard deduction, USD; null where the table shows n.a. (Utah's $966 is a credit, modeled separately). |
| marginal_rate_at_100k_taxable | float | Statutory bracket rate (%) at $100,000 of taxable income, single filer. |
| effective_rate_50k | float | Computed effective rate on $50,000 wage income, single filer (standard deduction applied; UT credit subtracted). |

| effective_rate_250k | float | As above, on $250,000 wage income. |
| progressivity_spread | float | top_marginal_rate_pct minus bottom_rate_pct (pp); 0 for flat or no-tax states. |
| income_tax_burden_tier | string | Dataset-internal tier on effective_rate_100k: None (0%), Low (<2.5%), Medium (2.5-4.49%), High (4.5-6.49%), Very high (>=6.5%). |
| rate_as_of | string | Vintage of the transcribed rates (2026-01-01; WV reflects SB 392 retroactive rates). |
| bracket_note | string | State-specific caveats: WA capital-gains scope, WV correction basis, unmodeled provisions (AL federal deduction, CT/NY recapture, exemption credits), zero-bracket assumptions. |
| source_url | string | Tax Foundation 2026 rates-and-brackets URL. |
| retrieved_at | string | Observation date of the transcription (2026-10-01); constant for idempotency. |
| row_hash | string | md5(abbr|brackets|std_ded|rate_as_of)[:16]. |
