Rehabilitation Tax Credits and the Certification Steps
The credit rewards work done to a standard, not simply work done to an old building. Two applications precede construction and a third follows it, and the middle one, describing the proposed rehabilitation, is where a project is won or lost.

The rule in short
Section 47 of the Internal Revenue Code allows a rehabilitation credit equal to twenty percent of qualified rehabilitation expenditures for a certified historic structure, taken ratably over five years beginning when the building is placed in service. The building must satisfy the substantial rehabilitation test, and the work must be certified under 36 CFR Part 67 as consistent with the Standards for Rehabilitation. Early disposition triggers recapture.
The federal rehabilitation credit pays a portion of the cost of putting an old income-producing building back into use. It is generous enough to change whether a project happens at all, and conditional enough that a single design decision can eliminate it. Two of the three qualifying tests are financial and mechanical. The third is a judgment about how the work treats the building.
The credit and the property it reaches
Section 47 allows a credit equal to twenty percent of the qualified rehabilitation expenditures with respect to a certified historic structure. The credit is taken ratably over a five-year period beginning with the taxable year in which the building is placed in service, so it arrives in installments rather than at once, a feature that materially affects how it is syndicated.
The word building does real work in the statute. The credit reaches buildings, not structures generally, so bridges, dams, grain elevators and similar works that are not buildings fall outside it however historic they are. A registered historic district for this purpose is one listed in the National Register, or a district designated under a state or local statute that has been certified by the Secretary of the Interior as substantially meeting the requirements for listing.
A certified historic structure is a building listed individually in the National Register, or located in a registered historic district and certified by the Secretary of the Interior as being of historic significance to that district. The building must also be depreciable, which excludes personal residences. Whether a building is listed is a question answered by the process described in the National Register criteria and nomination route.
The substantial rehabilitation test
A building qualifies only if the rehabilitation is substantial. The test compares qualified rehabilitation expenditures during a twenty-four month measuring period against the greater of the adjusted basis of the building or five thousand dollars. Where the rehabilitation is completed in phases under architectural plans and specifications completed before the work begins, a sixty-month period may be used instead.
The measuring period is selected by the taxpayer and it ends on a chosen date, so the timing of spending can decide whether the test is met. Adjusted basis is measured at the beginning of that period, which means an acquisition that allocates a large share of price to the building rather than to land raises the bar the project has to clear. Allocation between land and improvements is therefore a decision with consequences well beyond depreciation.
Qualified expenditures are the amounts chargeable to capital account for the structure itself. They exclude the cost of acquiring the building, the cost of enlargement, site work such as parking and landscaping, furnishings and personal property. Projects routinely fail the test not because they spent too little but because a large share of the spending fell outside the definition.
Certification is granted for the rehabilitation as a whole. A project that treated the exterior masonry impeccably and then removed the historic staircase and dropped a ceiling through the arched windows is evaluated on all of it together. There is no partial credit for the work that complied. This is why the description of rehabilitation is submitted before construction where possible, and amended whenever the design changes.
The three-part certification
Part 67 of Title 36 governs certification. The first application evaluates significance and establishes that a building in a registered historic district contributes to that district; a building already listed individually does not need it. The second describes the proposed rehabilitation and is reviewed against the Secretary of the Interior's Standards for Rehabilitation. The third requests certification of the completed work and is reviewed against what the second application approved.
The standards applied at the second stage are the Secretary of the Interior's Standards for Rehabilitation, a short set of principles addressing retention of historic character, avoidance of false historical appearance, preservation of distinctive features, repair rather than replacement of deteriorated features, and compatibility of new additions. They are principles rather than a specification, which is why reviewers reach different conclusions on similar work and why applicants who submit vague drawings get vague answers. Detailed window schedules, wall sections and finish specifications produce reviewable submissions.
All three are submitted through the State Historic Preservation Officer, which reviews and forwards them with a recommendation to the National Park Service. The federal decision is the operative one. Certifications can be conditioned, and a certification of completed work can be denied where the executed project departs from the approved description.
| Application | Question it answers | When it is filed | What a denial means |
|---|---|---|---|
| Evaluation of significance | Does this building contribute to the registered historic district? | Before or with the description of work | The building is not a certified historic structure |
| Description of rehabilitation | Does the proposed work meet the Standards for Rehabilitation? | Before construction, amended as design changes | The design must be revised or the credit abandoned |
| Request for certification of completed work | Was the approved work actually carried out? | After the building is placed in service | No credit, even where earlier parts were approved |
| Amendment sheet | Does a change from the approved description still comply? | Whenever the work departs from what was approved | The change must be corrected before completion review |
Recapture and what happens afterward
The credit is not final when it is claimed. Under section 50 of the Internal Revenue Code, disposition of the property or a cessation of its qualifying use within five years after it is placed in service triggers recapture of a portion of the credit, decreasing by one fifth for each full year the property was held. Partnership arrangements are drafted around this period, because a transfer of an interest can be treated as a disposition.
Certification can also be revoked where the Park Service determines the certification was obtained on the basis of a misrepresentation, or where work inconsistent with the approved description is performed. Owners who intend to hold the building long term often layer a recorded restriction on top of the credit, an instrument described in preservation easements and how long they bind. Where the same rehabilitation is also under municipal review, the standards can differ in emphasis even where the text is identical, as noted in local designation and certificates of appropriateness. None of this changes the baseline position set out in what listing does and does not restrict: the credit is a benefit an owner elects, and with it come conditions the owner accepted.
Points to carry away
- The credit equals twenty percent of qualified rehabilitation expenditures on a certified historic structure.
- The credit is taken ratably over five years beginning when the building is placed in service.
- Expenditures must exceed the greater of the building's adjusted basis or five thousand dollars.
- Acquisition cost, enlargement, site work and furnishings are not qualified expenditures.
- Certification runs through the state office to the Park Service, whose decision controls.
- Disposition or cessation of qualifying use within five years triggers proportional recapture.
Questions readers ask
Can an owner-occupied house qualify?
Not for the federal credit. The credit reaches qualified rehabilitation expenditures on depreciable property, which means the building must be held for the production of income or used in a trade or business. A personal residence is not depreciable, so the owner of a listed house who lives in it cannot claim the federal credit however careful the work is. Several states operate their own credits that do reach owner-occupied residences, on their own criteria and their own application routes. A homeowner should be checking the state program, not the federal one.
What happens if work is done before the second application is approved?
The work proceeds at the owner's risk. Nothing prohibits starting construction, and many projects do because of financing schedules, but the Park Service reviews what was actually done rather than what was proposed. Where completed work departs from the standards, the options narrow to correcting it or losing the certification for the whole project, since certification is granted for the rehabilitation as a whole rather than item by item. Submitting the description of rehabilitation early and amending it as design develops is the only reliable way to keep the review current with the site.
Does the state office decide the application?
No, though its opinion carries real weight. Applications are submitted through the State Historic Preservation Officer, which reviews them, may request additional information, and forwards them to the National Park Service with a recommendation. The Park Service makes the certification decision, and it can and does reach a different conclusion from the state office. An applicant who has a state recommendation in hand has an encouraging signal, not an approval, and should not treat the file as closed until the federal decision issues.

Listing on the National Register: Criteria and Process
Under 36 CFR 60.4 a district, site, building, structure or object qualifies for the National Register if it possesses integrity and meets one of four criteria: association with significant events, association with significant persons, distinctive design or construction, or the capacity to yield important information. Nominations travel through the State Historic Preservation Officer and a state review board to the Keeper, and 36 CFR 60.6 gives a private owner an objection that blocks listing.
Federal Undertakings and What Triggers Review
Under 36 CFR 800.16(y) an undertaking is a project, activity or program funded in whole or in part under the direct or indirect jurisdiction of a federal agency, carried out by or on behalf of an agency, carried out with federal financial assistance, or requiring a federal permit, license or approval. Section 800.3 requires the agency to decide first whether an undertaking exists and then whether it is the type of activity with potential to cause effects on historic properties.
The Consultation Sequence and Its Agreement Documents
Subpart B of 36 CFR Part 800 sets out four steps: initiation under 800.3, identification of historic properties under 800.4, assessment of adverse effects under 800.5, and resolution under 800.6. The preservation officer, Indian tribes, local governments, the applicant and interested members of the public are consulting parties. Resolution normally ends in a memorandum of agreement, or in a programmatic agreement for complex or repeated undertakings.
