Who earns it and how it is measured

The credit is earned on each metric ton of qualified carbon oxide captured with carbon capture equipment at a qualified facility and then stored in secure geological storage or used in a qualified way[1]. It runs for 12 years from the date the carbon capture equipment is placed in service[1].

The base amount is $17 per ton, or $36 for direct air capture; five times those amounts ($85 and $180) where the prevailing wage and apprenticeship requirements are met. The amounts are adjusted for inflation for tax years beginning after 2026[1].

A facility must begin construction before 1 January 2033, together with its carbon capture equipment or with capture built into its original design[1].

What changed in 2025

  • Parity for utilization. For facilities or equipment placed in service after 4 July 2025, carbon oxide that is used (including in enhanced oil or gas recovery) earns the same amount as carbon oxide in geological storage[1].
  • Foreign entities. For tax years beginning after 4 July 2025, no credit if the taxpayer is a specified foreign entity or a foreign-influenced entity[1], and the credit cannot be transferred to a specified foreign entity[2].

Selling it

§45Q is sold separately for each facility and each tax year of the 12-year period[2].

  1. Register each facility and renew the registration for each year you sell[3], at least 120 days before the return’s due date[4].
  2. Claim on Form 8933[5] and report the transfer on Form 3800, Part III, column (f)[6].
  3. Attach the transfer election statement to an original, timely return[7].

What buyers ask for on a §45Q deal: capture and injection or utilization measurements; the storage monitoring basis; the construction-start evidence; prevailing wage and apprenticeship records if the higher amount is claimed; and the contract terms for §45Q recapture, which applies if stored carbon oxide later escapes. The regulations treat a §45Q recapture event as separate from an excessive credit transfer[8], so the purchase agreement has to say who bears it.

Frequently asked questions

Does §45Q now treat all utilization pathways the same?

For facilities or equipment placed in service after 4 July 2025, the statute sets one amount for storage and qualified utilization[1]. Earlier equipment keeps the amounts that applied when it was placed in service.

Which form is used for §45Q?

Form 8933, Carbon Oxide Sequestration Credit[5].
