Nebraska's and West Virginia's 2026 figures were labelled provisional. Both were enacted law published by the state revenue agency — Nebraska's LB 754 phase-down step and West Virginia's SB 392, signed 31 March 2026 and retroactive to 1 January — so the label understated how settled they were.

Both are now marked final. The underlying rates did not change; only the status label did. Arkansas remains provisional, correctly: its rate is enacted but the state has not published its 2026 tables.

An article surveying state rate changes accumulated roughly 19 confirmed factual errors: wrong 2026 top rates for Arkansas, Idaho, Indiana, Iowa, Montana and South Carolina; a Tax Foundation “Total Rank” column whose figures matched no published ranking; a Minnesota rate misdated by a decade; Kentucky described as a post-2021 flat-tax convert when it has been flat since 2018; and understated migration figures for Arizona, New Jersey, North Carolina and Tennessee.

The article has been retired rather than patched. Its defensible core — that a large number of states have cut rates — has been rebuilt as a new piece in which every rate is computed directly from our own tax tables. The old URL redirects to the replacement.

We described Georgia as having legislated a phase-out of its income tax to zero by 2032, with standard deductions rising to $50,000 single / $100,000 joint, and printed a year-by-year rate schedule ending at 0.00%. We also gave Georgia's 2025 rate as 5.39%.

That plan was a Senate committee recommendation from January 2026, not law. The bill that passed — HB 463, signed 11 May 2026 — cuts the rate from 5.19% to 4.99% and then by 0.125 points a year to a floor of 3.99%, with each step subject to revenue triggers. Standard deductions rise to $18,000 / $36,000. Georgia's 2025 rate was 5.19%.

We described Washington's capital gains tax as a flat 7% above a threshold of approximately $262,000.

The threshold is $278,000, and the rate is no longer flat: SB 5813 added a second tier for tax year 2025 onward, taxing the first $1 million of taxable gains at 7% and everything above at 9.9%. Washington's maximum combined rate is 33.7%, not 30.8%.

We reported SB 6346 as effective for tax years beginning January 2027, passed in 2025, with a $1 million threshold for single filers and $2 million for joint filers.

SB 6346 moved through the legislature entirely in 2026 and was signed on 30 March 2026. The 9.9% tax takes effect 1 January 2028, with first returns due in 2029. The $1 million standard deduction does not double for couples — spouses and domestic partners share a combined $1 million regardless of how they file.

We applied the motor vehicle luxury tax rule — 8% on value above $100,000 — to boats and aircraft as well, and put the tax on a $250,000 boat at roughly $12,000.

ESSB 5801 sets three different rules. Motor vehicles: 8% above $100,000 from 1 January 2026. Noncommercial aircraft: 10% above $500,000 from 1 April 2026. Watercraft: 0.5% of the full selling price with no threshold, from 1 July 2026. A $250,000 boat owes $1,250, not $12,000.

Tables labelled with 2026 values carried stale exemptions: Connecticut $13,610,000 (the 2024 federal figure), District of Columbia $4,710,000, Maine $6,800,000 (the 2024 value), Rhode Island $1,774,583 (the 2024 value), Washington $2,193,000, and Minnesota ~$3.5M in one article against $3,000,000 in another.

For 2026: Connecticut $15,000,000 (it tracks the federal exclusion), District of Columbia $4,988,400, Maine $7,160,000, Rhode Island $1,838,056, Minnesota $3,000,000 (flat, not indexed). Washington's exclusion is $3,000,000 with a 20% top rate for deaths on or after 1 July 2026.

Hawaii was listed as taxing gains as ordinary income at 11%. Montana was described via a capital gains credit of up to 2%. South Carolina's nominal rate was given as 6.5%. Vermont was listed at a flat 8.75% with no exclusion. Colorado was credited with a general small-business stock exclusion. North Dakota, Missouri, Arizona and New Mexico were absent. A list of “nine states” named eight. The federal long-term brackets were 2025 figures.

Hawaii applies an alternative maximum rate of 7.25%. Montana's 2% credit was repealed; it now runs a separate 3.0%/4.1% schedule. South Carolina's 2026 top rate is 5.21%, making the effective rate on gains about 2.92%. Vermont excludes the first $5,000. Colorado's subtraction is limited to farmers and ranchers on specific agricultural property. Missouri exempts gains entirely from 2025; North Dakota excludes 40%, Arizona 25%, New Mexico the first $2,500. Eight states tax neither income nor gains — Washington is the ninth no-income-tax state but does tax gains. Federal 2026 brackets are $49,450 and $545,500.

Tennessee's business tax was given as 0.3%–1.8% of gross receipts. New Hampshire's business enterprise tax was given as 0.5%, and its repealed Interest and Dividends tax was described as having been 5%. Alaska was called the only state with neither an income nor a sales tax, while a later paragraph correctly said there were two.

Tennessee's statutory business tax runs 0.02%–0.1875%. New Hampshire's business enterprise tax is 0.55%. The Interest and Dividends tax was phased down before repeal — 5% for 2022, 4% for 2023, 3% for 2024. Alaska and New Hampshire both levy neither an income nor a state sales tax.

The feed served a legacy set of ten articles whose URLs had no corresponding pages, so every item in the feed resolved to a 404. The feed also advertised a different domain than the sitemap.

The feed is now generated from the published articles, and both the feed and the sitemap use the same base URL.

Our California tables showed a top marginal rate of 12.3%, omitting the 1% Mental Health Services Tax on income above $1 million.

California's true top rate is 13.3% and has been since 2004. The tables now reflect it. This was a modeling omission on our side, not a change in California law — which is why our rate-change coverage counts California as unchanged rather than as a state that raised its rate.
