Not released
These calculator URLs are not published or included in the sitemap. A pending validation is not the same as an unavailable official tax table.
- District of Columbia: Pending 2026 withholding verification. The current official forms index lists 2026 employer returns but marks employee D-4 and D-4A under review. The latest explicit withholding-method notice located was OTR2022-08, which names the2022 allowance and rate schedule. Its 2026 applicability, current allowance amount, and three 2026 official-table hand checks have not been confirmed; historical tables were not republished as2026.
- Oregon: Official 2026 sources are available, but full validation has not passed. The computer formula does not explicitly define withholding when annual taxable wages minus federal income-tax withholding and the payroll standard deduction produces a negative BASE. The alternative wage tables apply under different withholding-certificate conditions and cannot establish the missing computer-formula rule. Four ordinary-income research cases pass, but they do not validate this unresolved low-income interval; this state is not approved for publication.
