House Finance hears plan to modernize corporate sourcing and phase out C‑corp tax by 2031

Summary
The Department of Revenue told the House Finance Committee HB 284 would shift Alaska from cost‑of‑performance to market‑based sourcing—estimated to raise about $15 million annually—and phases the corporate income tax rate down to 0% in 2031; lawmakers pressed DOR on fiscal impacts and stability.
Acting Tax Director Brandon Spanos and Department of Revenue economists presented the corporate income tax section of House Bill 284, saying the bill would modernize how Alaska sources corporate sales and reduce the corporate income tax rate to 0 in 2031.
The Department framed two headline changes: move sourcing from a cost‑of‑performance approach to market‑based sourcing so sales are attributed where customers are located, and phase the corporate income tax rate to 0 by 2031. "It doesn't add a digital tax," Spanos told the committee. "What it does is it captures sales that aren't currently being captured in the numerator." He said the department estimates market‑based sourcing would raise about $15,000,000 per year (midpoint of a modeled range) because it would capture sales currently reported to other states.
Why it matters: market‑based sourcing would require many multistate vendors — technology, finance, e‑commerce and other firms that market to Alaskans from outside the state — to include Alaska sales in their apportionment numerator. Spanos said firms with a strong in‑state physical presence but few Alaska customers (for example, some processors shipping most product out of state) could pay less, while purely Alaska companies would be unaffected.
Department economists told the committee SB 113 (a vetoed Senate bill) had both market‑based sourcing and a separate single‑factor carve‑out for "highly digitized" businesses; that carve‑out was one factor behind the governor's veto of SB 113, they said. Stickel, the department's chief economist, explained HB 284 carries forward the market‑based sourcing component but not the singled‑out carve‑out for highly digitized businesses.
Fiscal context and questions: the department said its fiscal note breaks out near‑term impacts and longer‑term effects. Stickel summarized estimates tied to the corporate rate change: a half‑year impact in FY2031 of approximately $145 million non‑petroleum and $115 million petroleum, and full‑year FY2032 impacts of roughly $295 million (non‑petroleum) and $245 million (petroleum), based on the department's fall 2025 forecast. Committee members repeatedly pressed how the package affects long‑term stability, credit ratings and whether the 2031 phase‑out would undermine incentives or expose the state to future deficits.
Members also asked implementation questions: Michael Williams, the department's corporate tax manager, said industry‑specific apportionment rules in regulation would need revision to conform to market‑based sourcing and that DOR expects to issue regulations to implement the change.
What remains: lawmakers asked the department for additional modeling and a consolidated written analysis showing distributional impacts (how residents, PFD‑eligible recipients and different industries would fare) and clearer comparisons with past proposals. The committee moved on to the oil and gas section after about an hour on corporate tax.
The committee did not vote on HB 284 during this session; the presentation and Q&A informed members' views, and DOR offered to provide further fiscal and field‑level modeling on request.
