Domestic Content Bonus Underwriting for Solar

Domestic Content Bonus Underwriting for Solar

The domestic-content bonus is only financeable when the procurement record can support it. Module origin alone is not a complete test; the analysis has to follow the IRS steel, iron and manufactured-product rules and the applicable adjusted-percentage threshold.

The current technical framework is set out in IRS Domestic Content Bonus Credit and IRS Instructions for Form 3468. These references are applied specifically to the underwriting analysis in Domestic Content Bonus Underwriting for Solar.

Credit Relevance of Solar Domestic Content Bonus Underwriting

For 48E projects beginning construction in 2026, the IRS Form 3468 instructions state a 50% adjusted percentage for the manufactured-products cost test, while steel and iron requirements continue to apply separately. A domestic-content certification statement is required when claiming the bonus. For financing purposes, the tax analysis should be translated into a closing-condition matrix rather than left as a tax-counsel workstream that sits outside the lender model.

Run the base case with documented domestic-content qualification and a downside case without the bonus. If debt or tax-credit bridge sizing depends on the extra percentage points, the lender should require a component-level evidence package before funding. This keeps the tax-credit source of funds tied to the exact diligence items that determine whether the proceeds arrive on time and in the amount assumed.
