The mechanic, in one paragraph
CSBFP is built to finance asset purchases — equipment, leasehold improvements, real property, intangibles, and (within sub-limits) working capital. Most CSBFP loans are arranged before the asset is purchased, but the program also accommodates the common real-world case where a business has already bought the asset out of pocket, on a short-term loan, or on a credit line, and now wants to restructure that purchase into a CSBFP term loan. The 365-day rule is what makes that retroactive financing possible: as long as the asset was acquired within the last 365 days, CSBFP can still cover it.
The key facts
- Look-back window: 365 days from the asset purchase date to the CSBFP loan approval date.
- Prior window: 180 days, before the program was updated in July 2022. The change effectively doubled the retroactive financing window.
- What it applies to: the standard list of CSBFP-eligible asset categories — real property (where the business uses at least 50% of the property for operations), leasehold improvements, equipment (including software and commercial vehicles), and intangible assets. The asset must still qualify under all the other program rules.
- Documentation: the lender will want the invoice, the proof of payment, and clear evidence of when the asset was acquired. The 365-day window is measured to the day, so the paper trail matters.
- What it does not change:the program’s other eligibility rules. A 365-day-old asset purchase is still subject to the loan-amount caps, the personal-guarantee cap, the lender’s underwriting, and the borrower’s own qualification on revenue, structure, and operations.
When it is useful
Three scenarios where the 365-day rule changes the financing conversation.
1. Equipment already purchased on a credit line or short-term loan. A business that financed a piece of equipment on a higher-cost facility — a working-capital line, a vendor finance deal, even a personal credit card in some cases — can use a CSBFP term loan to refinance the purchase under the program’s rate-capped, longer-amortization structure. The original short-term facility gets paid out at closing; the CSBFP loan takes its place.
2. Leasehold improvements completed during a build-out. Construction trades on a leasehold build-out often want to be paid as work progresses, before a CSBFP application can be submitted and approved. The 365-day rule lets the business settle with the trades out of pocket (or on a temporary line) and then restructure the entire leasehold spend into a CSBFP term loan once the build-out is finished and the operating history is established.
3. Real-property purchases timed around a deal close. Commercial real-estate transactions sometimes have to close on the seller’s timeline, which can be faster than a CSBFP application can move. Real property is one of the eligible categories the 365-day window covers, so a purchase made inside the last year can still be considered for CSBFP financing — subject to the use, the borrower, the property, and the lender’s underwriting all qualifying. (The canonical rule to start from is that CSBFP cannot be used to refinance pre-existing debt with the same lender; how a cross-lender restructure is treated depends on the specific facility and the structure of the deal.)
What about lines of credit?
The canonical CSBFP guidance describes the 365-day rule in the context of asset financing — real property, leaseholds, equipment, and intangibles — which are term-loan categories. CSBFP lines of credit finance working capital (inventory, payroll, rent, software development costs, professional fees); for the line-of-credit mechanics and how they sit alongside the term loan, see the comparison in CSBFP term loan vs. line of credit.
The practical limit
The 365-day rule is generous, but it is not unlimited. An asset purchased 18 months ago is outside the window — there is no retroactive way to bring it back into the CSBFP envelope. For assets that have aged out, the financing path is conventional bank debt, BDC, or alternative funding (see alternative funding options).
For an asset purchase still inside the window, the strongest move is to start the CSBFP application before the clock runs down.
