Direct pay (also called elective pay under Section 6417) for an investment tax credit (ITC) is tied to the owner’s tax return, not to project completion. The payment comes only after a valid return is filed and the IRS processes it. Filing early won’t speed it up. For owners who file on time, the IRS’s stated expectation is payment within roughly 45 days of the return’s due date. In Walker Blue’s experience, owners should plan on about 15 to 20 weeks after filing.
For a school district, municipality or other tax-exempt owner, the gap between finishing the project and receiving the cash belongs in the cash-flow plan from day one.
This article covers ITC projects under §48 and §48E. Production credits follow the years in which qualifying production occurs.
What sets the direct pay timeline?
Work backward from the payment you’re expecting:
- The property is placed in service. For ITC projects, this generally sets the tax year in which the credit is claimed.
- That tax year closes.
- IRS pre-filing registration is completed and the return is filed with a valid election.
- The original due date passes and the IRS processes the claim.
So the real question isn’t “How long does the IRS take?” It’s “Which tax year contains our placed-in-service date, when is that return due, and will we be ready?”
When should you complete IRS pre-filing registration?
The owner must complete IRS pre-filing registration and get a registration number before filing. Two points owners often miss:
- The property must already be placed in service before it can be registered.
- The IRS recommends registering at least 120 days before you plan to file.
The 120 days is a recommendation, not a guaranteed turnaround. The IRS may come back with questions. Assembling project records during construction avoids a scramble at the end.
A registration number does not mean the credit is approved. It’s a filing prerequisite, not a determination of eligibility.
What is the deadline to elect direct pay?
The direct-pay election must be made on a timely filed original return, including any extension. Miss that deadline and the credit is lost, not just delayed.
Tax-exempt owners generally file Form 990-T, with Form 3800, the applicable credit form (such as Form 3468) and required attachments. For entities filing only to make the election, the return is due on the 15th day of the fifth month after tax year-end. A six-month extension is available, but it pushes your payment date out with it.
Does filing early speed up the payment?
The IRS has said owners aren’t entitled to payment before the return’s original due date, even if they file sooner. For owners who file on time, the IRS’s stated expectation is payment within roughly 45 days of the due date.
In Walker Blue’s experience, owners should plan on about 15 to 20 weeks after filing. Treat any receipt date as an assumption in the financial model until the money actually arrives.
Example: a December completion, paid the following winter
Consider a school district with a June 30 fiscal year:
- Property placed in service: December 2026
- Tax year ends: June 30, 2027
- Original return due date: November 15, 2027
- Planning window for payment: late 2027 into early 2028
Filing in September 2027 would not make September the payment date. This is an illustration, not a payment forecast.
Your accounting year may not be your direct-pay tax year
Before building the model around the owner’s fiscal year, confirm its federal filing history. Certain entities with no prior federal filing requirement may adopt a calendar or fiscal year on their first direct-pay return, as long as their books support it.
That flexibility doesn’t let an owner change an established tax year to accelerate a payment. Confirm the approach with your tax adviser.
What can reduce the payment amount?
A reliable payment schedule needs a supported credit calculation. Four issues come up often.
Domestic content (urgent for 2027 starts). For projects beginning construction after 2025, failing domestic content requirements eliminates direct pay entirely, unless a statutory exception applies. The IRS’s attestation process for claiming those exceptions currently covers projects beginning construction before January 1, 2027, unless Treasury issues further guidance. Owners planning 2027 construction starts should address this now.
2025 law changes. The 2025 tax legislation (OBBBA) set new begin-construction and placed-in-service deadlines for wind and solar. It also added foreign-entity (FEOC) restrictions. Other technologies, such as geothermal and storage, have different timelines. Confirm which rules apply to your project before counting on the credit.
Tax-exempt bond financing. Bond financing can reduce the credit by the lesser of 15% or the bond-financed share of the project. That’s a reduction of the credit amount, not 15 points off the credit rate.
Grants. Tax-exempt grants don’t automatically reduce eligible basis. However, restricted grants plus the credit generally can’t exceed the property’s cost.
How to plan for the funding gap
- Lock down the tax year before approving the cash-flow model. Include the placed-in-service date, due date, registration target, filing date and a delay contingency.
- Watch completion timing. A project placed in service just after year-end can slip a full claim year. The placed-in-service date has to follow the project facts.
- Size bridge financing to a conservative receipt date. Bridge or debt financing generally doesn’t prevent a direct-pay election, but carrying costs and the risk of a reduced or delayed payment belong in the analysis.
- Compare ownership structures early. If third-party ownership is on the table, review eligibility, pricing, operating obligations and exit terms separately.
Frequently asked questions
How long does direct pay take?
For owners who file on time, the IRS’s stated expectation is payment within roughly 45 days of the return’s due date. In Walker Blue’s experience, owners should plan on about 15 to 20 weeks after filing.
Can we receive direct pay before filing?
No. You must file the required return with a valid election, and filing early doesn’t accelerate payment.
Does a registration number mean the credit is approved?
No. Registration is required to file but doesn’t establish that the project qualifies.
What if we miss the filing deadline?
The election must be on a timely filed original return, including extensions. A late return can mean losing the credit.
What should our project file contain?
The eligibility analysis, cost support, placed-in-service evidence, prevailing wage, apprenticeship and domestic content records, financing and grant documents, registration records, and the filed return and attachments.
Can an overpayment be clawed back?
Yes. An excessive payment must be repaid, plus an additional 20% unless the owner shows reasonable cause. Keep documentation well after the cash arrives.
