§45Q Carbon Capture Credit: A Buyer's Guide to Transferable 45Q Credits

The §45Q carbon oxide sequestration credit pays per metric ton of carbon oxide that is captured and then stored or used under the statute's rules. It is one of the credits a buyer can purchase for cash under §6418. This guide covers how 45Q credits are earned, what changed in 2025, the recapture and foreign-entity rules that matter to a buyer, and how a 45Q purchase compares with a §48E investment credit.

How the 45Q credit is earned

• Per ton, over 12 years. For carbon capture equipment placed in service on or after February 9, 2018 (the Bipartisan Budget Act of 2018), the credit applies to qualified carbon oxide captured during the 12-year period beginning when the equipment was originally placed in service (§45Q(a)(3)(A)).
• Stored, used for enhanced recovery, or utilized. The carbon oxide must be disposed of in secure geological storage, used as a tertiary injectant in a qualified enhanced oil or natural gas recovery project and stored, or utilized under §45Q(f)(5) (§45Q(a)(3)(B)).
• Who earns it. Generally the person that owns the carbon capture equipment and physically or contractually ensures the capture and disposal, utilization or use (§45Q(f)(3)(A)(ii)). That person can elect to let the party that disposes of or uses the carbon oxide claim the credit instead (§45Q(f)(3)(B)). Ask which party is the seller and why.
• Construction start. The facility's construction must begin before January 1, 2033, with capture equipment construction also beginning before then or included in the original design (§45Q(d)(1)).
• Annual capture minimums. 1,000 metric tons for direct air capture; 18,750 metric tons for an electricity generating facility, which also needs capture design capacity of at least 75% of the unit's baseline; and 12,500 metric tons for other facilities (§45Q(d)(2)).

Credit amounts after the 2025 changes

Equipment placed in service after July 4, 2025	Base amount per metric ton	With prevailing wage and apprenticeship (5×)
Industrial or power capture: storage, enhanced recovery or utilization	$17	$85
Direct air capture facility	$36	$180

Source: §45Q(b)(1)(A)-(B) and (h)(1). The statute sets $17 for taxable years beginning after 2024 and before 2027, with inflation adjustment after that. The One Big Beautiful Bill Act (P.L. 119-21, §70522) gave enhanced recovery and utilization the same rate as geological storage for facilities or equipment placed in service after July 4, 2025. Under the IRS Form 8933 instructions, earlier equipment uses $17 for storage and $12 for enhanced recovery or utilization. The 5× multiplier depends on prevailing wage and apprenticeship rules or a pre-guidance construction start (§45Q(h)(2)).

Recapture is the buyer's issue

Treasury regulations require recapture when stored carbon oxide leaks (§45Q(f)(4); 26 CFR §1.45Q-5). The recapture period begins on the date of first injection and ends on the earlier of three years after the last taxable year in which the credit was claimed (or could have been claimed and was carried forward) or the end of required monitoring (§1.45Q-5(f)).

For a transferred credit, the §6418 regulations require the seller and the buyer to follow a notification process, and recapture affects the transferee (26 CFR §1.6418-5(e)). A §45Q recapture event is not an "excessive credit transfer," which is a separate 20% penalty regime (§1.6418-5(a)(5)). Because the 12-year credit period plus a three-year tail is much longer than §48E's five-year §50 period, the length and strength of the seller's indemnity and any insurance matter more. See indemnity and insurance terms.

Secure storage standards to check

Under 26 CFR §1.45Q-3(b), carbon oxide counts as disposed of in secure geological storage when it is injected into a well that complies with Underground Injection Control or other applicable rules and, for storage that is not enhanced recovery, meets EPA's 40 CFR part 98 subpart RR requirements; enhanced recovery projects may instead follow CSA/ANSI ISO 27916:2019. Ask for the monitoring, reporting and verification plan and the lifecycle analysis for any utilization claim (§45Q(f)(5)(B)).

Foreign-entity rules

• No 45Q credit is determined for taxable years beginning after July 4, 2025 if the taxpayer is a specified foreign entity or a foreign-influenced entity (§45Q(f)(10)).
• A 45Q credit cannot be transferred to a buyer that is a specified foreign entity (§6418(g)(5)).
• The material assistance cost ratio rules in §7701(a)(52) are written for §45Y and §48E facilities and §45X components, not 45Q. See FEOC risk for credit buyers.

Buyer diligence checklist

1. IRS pre-filing registration number for the credit year. A production credit needs a registration for each year an election is made.
2. Form 8933 support: tons captured, measured at the source, and verified at disposal, injection or utilization (§45Q(c)).
3. Placed-in-service dates for the equipment, which set the rate (before or after July 4, 2025) and the 12-year window.
4. Prevailing wage and apprenticeship records if the 5× amount is claimed.
5. Subpart RR or ISO 27916 documentation and the monitoring plan.
6. Seller and buyer foreign-entity representations.
7. Indemnity that covers leakage recapture for the full recapture period, plus credit support from a creditworthy party.
8. For individuals: the passive activity limit applies first (§469). See §469 and transferable credits.

45Q vs §48E for a buyer

	§45Q	§48E
How the credit arises	Per metric ton each year for 12 years	Once, when the facility or storage is placed in service
Recapture	Leakage recapture under §1.45Q-5; period can run three years past the last credit year	§50 recapture over five years
Supply	Few, large industrial projects	Broad pool of solar, storage and other projects
Foreign-entity rules	Taxpayer status (§45Q(f)(10)); no transfer to a specified foreign entity	Taxpayer status plus material assistance for construction beginning after 2025
Form	Form 8933, then Form 3800	Form 3468 Part V, then Form 3800

Neither credit is risk-free, and a lower price usually reflects more risk or less certainty. Compare all-in cost per dollar of credit after indemnity, insurance and fees. Pricing context: §48E pricing.
