A graduated state credit on top of the 20% federal historic credit, with three 5% bonuses and a $4.5 million project cap — and one election you cannot undo.
North Carolina’s credit for rehabilitating historic structures piggybacks on the federal program: qualify for the 20% federal credit and the state adds a graduated credit with three bonuses. It is the right answer for most historic projects in the state — but not for a qualifying mill, which should be compared against the uncapped Article 3H mill credit first. Jump to a section:
| Quick Facts — NC Historic Credit (Income-Producing) | |
|---|---|
| Base credit | 15% of QREs up to $10M; 10% of QREs from $10M–$20M; 0% above $20M |
| Bonuses | +5% development tier 1 or 2; +5% targeted investment (eligible former manufacturing, agricultural warehouse or utility site, 65% vacant for 2 years); +5% education bonus |
| Per-project cap | $4,500,000 (G.S. 105-129.105(d)) |
| Federal credit | Required — the project must qualify for the 20% federal historic credit through SHPO and NPS Parts 1, 2 and 3 |
| Tax credited | Binding election among franchise, income, or gross premiums tax; nine-year carryforward |
| Sunset | Expires for expenditures incurred on or after Jan 1, 2030; for earlier expenditures, property must be placed in service by Jan 1, 2032 |
| Cannot combine with | The Article 3H mill credit, with respect to the same activity — you elect one |
The graduated structure means the credit stops growing at $20 million of qualified spend, and the $4.5 million cap binds well before that on a project reaching the bonuses. For a large rehabilitation the practical question is not how to maximise Article 3L — it is whether the building qualifies for Article 3H instead.
We confirm tier and targeted-investment eligibility, model the cap against your budget, test the Article 3H alternative, manage the SHPO and NPS certification path, and place the federal-plus-state package with investors.

| Quick Facts — Non-Income-Producing | |
|---|---|
| Credit amount | 15% of rehabilitation expenses |
| Minimum spend | $10,000 |
| Cap | $22,500 per discrete property parcel |
| Frequency | Not more than once in any five-year period |
| Federal credit | Not applicable — the federal 20% credit requires income-producing use |
This is a homeowner credit rather than a development credit, and at $22,500 it is not a syndication candidate. We note it here for completeness — if your project is a residence, your CPA can claim this directly without a consultant.

| Bonus | What it requires |
|---|---|
| +5% Development tier | The site sits in a development tier one or tier two county. North Carolina ranks all 100 counties annually by economic distress; tier 1 and 2 cover most of the state's small-town historic inventory. |
| +5% Targeted investment | An eligible targeted investment site: former manufacturing or ancillary use, agricultural-products warehouse, or public/private utility; a certified historic structure; and at least 65% vacant for two years. |
| +5% Education | Added by S.L. 2021-180 §42.7A for tax years beginning on or after January 1, 2021 — a structure originally used for and continuing in educational use. |
With all three, the credit on the first $10 million tranche reaches 30%. Note that published summaries — including some official pages — still describe this credit as “15–25%,” which predates the education bonus. The $4.5 million per-project cap applies regardless of how many bonuses a project earns.
Bonus eligibility is determined at certification, not at closing, and the targeted-investment test in particular is easy to lose by re-tenanting early. We screen for all three before the budget locks.
Which bonuses does my project reach?Official references: G.S. 105-129.105(a)–(c); S.L. 2021-180 §42.7A.
For income-producing projects, 15% of qualified rehabilitation expenditures on the first $10 million and 10% on expenditures between $10 million and $20 million, plus 5% bonuses for a development tier one or two location, for a targeted investment site, and for continuing educational use. The credit is capped at $4.5 million per project.
Yes — Article 3H, the standalone mill rehabilitation credit, was reenacted in 2021 and is worth 40% of qualified expenditures in tier one and two counties with no per-project cap. It cannot be combined with the Article 3L historic credit on the same activity, so a qualifying mill should compare the two before certifying. See our Article 3H guide.
Yes, and it must be: the state credit requires the project to qualify for the 20% federal historic rehabilitation credit. A qualifying project combines 20% federal with 15% to 30% state on qualified expenditures, subject to the $4.5 million state cap.
It expires for expenditures incurred on or after January 1, 2030. For expenditures incurred before that date, the property must be placed in service by January 1, 2032. S.L. 2021-180 moved these dates out from 2024 and 2026.
It caps the state credit per project. A bonus-eligible project reaches it at roughly $18 to $20 million of qualified expenditures. Larger projects still benefit; the cap changes how the state piece is priced and structured relative to the uncapped federal credit — and it is the main reason a qualifying mill is usually better off under Article 3H.
Often, yes. Buildings can be listed individually or as contributing structures in a historic district, and a National Register nomination can run in parallel with project planning. The earlier we look, the more options remain open.
From SHPO relationships to county tier maps to the 3H-versus-3L election, we work these credits from inside the state.
