A bank branch looks like a small office building and depreciates like something else entirely. The security infrastructure, the teller line, the drive-through and the parking that surrounds it are all identifiable-function property, while the vault that everyone assumes is the big reclassification item is usually the one that stays. Cost Seg Smart models bank branches as a first-class type with a dedicated component library covering vault and security systems, teller and drive-through infrastructure, branded interior finishes, and the site work a branch carries relative to its small footprint.
The signature fact: the vault is the item most often gotten wrong, in both directions. A poured reinforced-concrete vault enclosure is structural and generally stays 39-year. The vault door and frame are a different question — a multi-ton engineered door assembly is a manufactured unit serving the security function, and whether it reads as §1245 equipment or as part of the structure depends on how it is mounted and how integral it is to the enclosure. It is worth engineering review rather than a default, because it is a large single line. Modular or prefabricated vault panel systems, which are bolted assemblies rather than poured walls, sit further toward the equipment side of that line.
Reclass benchmark for bank branches
Engine-modeled accelerated reclass across standardized branch configurations:
| Branch configuration | Typical accelerated reclass |
|---|---|
| In-line or storefront branch, no drive-through | 15–20% |
| Standalone branch, modest lot, one or two drive-through lanes | 20–26% |
| Standalone branch, large lot, multi-lane drive-through and ATM island | 25–32% |
| Branch with a regional-office or operations component above | 18–24% |
Typical bucket composition for a standalone branch with a drive-through:
| Bucket | Median % of basis |
|---|---|
| 5-year (Section 1245 personal property) | 10–15% |
| 7-year (Section 1245 specialty) | 1–2% |
| 15-year (Section 1250 land improvements) | 8–14% |
| 39-year (Section 1250 structural) | 68–81% |
The 15-year bucket carries more weight here than in most office-class buildings. A standalone branch sits on a lot sized for stacking drive-through traffic and customer parking, so paving, the canopy foundations, the ATM island and site lighting are large relative to a building that is often only 3,000 to 5,000 square feet.
What reclassifies in a bank branch
5-year personal property (Section 1245):
- Teller-line millwork, undercounter steel, cash drawers and transaction counters
- Drive-through pneumatic tube systems, deal drawers, remote transaction units
- ATMs, ITMs and their surrounds where owned by the property owner rather than leased
- Night depository equipment
- Security systems: cameras, DVR/NVR, alarm panels, duress and monitoring hardware
- Electronic access control, card readers, mantrap and door control hardware
- Safe deposit box nests (removable modular units, distinct from the vault enclosure)
- Branded interior finishes, decorative and accent lighting, digital display and signage electronics
- Officer-platform and lobby furniture, casework and merchandising fixtures
- Data and low-voltage cabling serving branch equipment; dedicated server-room cooling
- Raised access flooring serving the equipment room
7-year specialty (Section 1245):
- Built-in casework specific to branch operation (platform desks, coin and currency stations)
15-year land improvements (Section 1250):
- Drive-through lanes, stacking paving, customer and staff parking
- Canopy foundations and footings, ATM island, bollards
- Site lighting, directional and pylon signage structures
- Landscaping, irrigation, curbs, walkways and site drainage
39-year structural (Section 1250):
- Building shell, roof, structural frame and foundation
- The poured vault enclosure itself
- Base plumbing, electrical service and building HVAC distribution
- Permanently affixed interior partitions and hard finishes
Why branch studies differ from ordinary office studies
The building is small and the site is not. A 4,000-square-foot branch on a one-acre parcel carries land improvements at a ratio an office tower never sees. Because the 15-year bucket scales with paving and site work rather than floor area, the smallest-looking branches often reclassify the highest percentage.
Branded fit-out turns over on a program cycle, not a building cycle. Bank interiors are rebuilt to a corporate image program on a schedule far shorter than 39 years. Where finishes, signage and display systems serve that branding and merchandising function rather than the structure, they belong in the short-life pools, and their documented replacement cycle is part of what supports that treatment.
Security is an operating system, not a wall. Cameras, access control, alarms, duress hardware and monitoring equipment serve an identifiable function and are removable. The enclosure they protect is the part that stays.
Consolidation makes partial dispositions relevant. Branch networks close, relocate and remodel constantly. When a branch is renovated or a component retired, a partial disposition election can write off the remaining basis of what was removed instead of depreciating an asset that no longer exists. That analysis depends on having component-level detail in the first place, which is what a study produces.
Illustrative (modeled, not a completed client study). On a $3.2M standalone branch with roughly $2.6M in depreciable basis, a two-lane drive-through and a full customer lot, an accelerated share near 22% would move roughly $570K into the 5- and 15-year pools. Actual results depend on the vault construction, the drive-through and ATM configuration, lot size, documentation, and the positions taken with your CPA.
Frequently asked questions
Does the vault reclassify?
Usually not the enclosure. A poured reinforced-concrete vault is structural and generally stays 39-year. The vault door and frame assembly is a separate, fact-specific question worth engineering review, and modular bolted vault panel systems sit closer to equipment than a poured enclosure does. Safe deposit box nests, which are removable modular units, are a different item again and generally do reclassify.
We lease the ATM. Does that change anything?
Yes. A leased ATM is not in your depreciable basis, so it is not part of your study. The island, foundation, bollards, canopy and site lighting around it usually are, as land improvements. The same split applies to any leased equipment in the branch.
Our branch is a condo unit inside a larger building.
The study covers your unit’s basis plus any allocated interest in common elements. There will be little or no land improvement component, so the accelerated share typically lands at the lower end of the range, driven by the teller line, security systems and branded fit-out.
We are closing or remodeling branches. Is a study still worth it?
Often more so. A study produces the component-level detail that makes a partial disposition election possible when you remove or replace assets, and a lookback study on a branch acquired in an earlier year can be caught up with Form 3115 in the current year without amending returns.
Does this work for a credit union or a branch inside a retail store?
Yes for a credit union; the property analysis does not depend on the charter. An in-store branch is effectively a tenant fit-out, so the study covers the improvements you paid for, and the accelerated share is driven almost entirely by the teller line, security and finishes rather than site work.
