How Are Assessment Areas Defined for Online-Only Banks? The Branchless CRA Delineation Kit

A worksheet kit for branchless banks: map retail lending to counties, test the retail lending assessment area trigger, and build documentation to examination standards.

Quick answer

An online-only bank with no branches delineates no facility-based assessment area at all, because facility-based assessment areas attach to physical branch locations. Instead, a large branchless bank must define one or more retail lending assessment areas: whole counties where it originated at least 100 home mortgage loans or at least 150 small business or small farm loans in each of the prior two calendar years — a per-year count, not a two-year total — under the delineation definitions at 12 CFR 25.12 (OCC), 345.12 (FDIC), and 228.12 (Federal Reserve). The rule's condition that more than half of a loan category be made outside facility-based areas applies only to banks with branches, so a branchless bank satisfies it automatically.

  1. Confirm your bank category: Verify your institution meets the current asset thresholds for a large bank, because retail lending assessment area duties attach to large banks under the 2023 rule.
  2. Document the branchless premise: Record that your bank operates no staffed banking facility, so no facility-based assessment area is delineated and every retail loan counts as outside any facility-based area.
  3. Geocode two years of lending: Pull home mortgage loans (closed-end and open-end lines, as the rule defines the term) and small business or small farm originations for the two preceding calendar years and map each loan to its census tract and county.
  4. Run the county trigger screen: Flag every county where originations reach at least 100 home mortgage loans or at least 150 small business or small farm loans in each of the prior two calendar years — the rule counts each calendar year separately, so a county over the line one year and under it the next does not trigger.
  5. Test the outside-area share: Confirm that more than half of your lending in each flagged category originated outside facility-based assessment areas; a branchless bank satisfies this more-than-50-percent condition automatically because it has no facility-based areas.
  6. Assemble whole-county areas: Group every triggered county, plus county equivalents such as parishes and independent cities, into one or more retail lending assessment areas drawn along county lines.
  7. Build the delineation file: Save the data sources, cutoff dates, county tallies, and grouping rationale together so the delineation can be reproduced on request.
  8. Calendar the annual re-test: Schedule next year's screen against the new two-year window and check for any rule amendments adopted since the 2023 final rule before finalizing the file. The delineation text as currently published in the eCFR matches this screen — no amendment adopted since the 2023 rule has changed the thresholds or their per-year counting — but verify the current text before the file goes to examination.

Summary

Online-only banks draw CRA assessment areas from where they lend, not where they branch. This kit walks through the county-level trigger screen, whole-county area assembly, and the documentation file behind them.

This resource helps readers connect how are assessment areas defined for online-only banks to classroom practice, standards-aware implementation, and responsible next steps for schools and sponsors.

Who This Kit Is For

Under the 2023 CRA final rule, an online-only bank defines its assessment areas from where it lends rather than where it sits. Facility-based assessment areas are tied to branch locations, so a bank with no branch network delineates none. Instead, a large branchless bank maps its retail lending to counties and must create one or more retail lending assessment areas wherever its originations cross the rule's loan-count thresholds. The rule applies those thresholds 'in each of the prior two calendar years' — a per-year screen, not a two-year total — under the delineation definitions at 12 CFR 25.12 (OCC), 345.12 (FDIC), and 228.12 (Federal Reserve). This kit turns that exercise into worksheets you can complete in an afternoon. The worksheets below run as a single sequence — the Branchless Delineation Lab — where each output feeds the next.

It is written for CRA officers, compliance analysts, and consultants at internet banks and branchless community lenders preparing for the 2023 rule's phased compliance dates. It also helps partnership teams understand why the assessment area file shapes how examiners read a lending footprint, and, under the modernized rule, why community development activity is now judged bank-wide rather than inside branch footprints alone.

  • Large internet banks subject to the retail lending test that originate loans across dozens of counties without operating a single branch
  • Neobank compliance teams reconciling home mortgage and small business origination files against county boundaries
  • Consultants and internal audit staff building or reviewing a branchless bank's assessment area documentation file
  • Fintech program and partnership leads at branchless banks whose lending data feeds the county tally and needs to be mapped to the right geographies

What Is Included

The kit is a working packet, not a summary. Every worksheet feeds the next one: a bank-profile screen, a county-level trigger tally, an assembly plan, and a documentation checklist you can hand to internal audit or your examination support team. Worked scenarios show what the outputs look like for three different branchless lenders.

  • Bank Profile Screen — confirms which assessment area rules apply to your institution and why facility-based areas drop out for branchless banks
  • County Trigger Tally — a worksheet that rolls census-tract loan data up to counties, captures home mortgage loans (closed-end and open-end lines, as the rule defines the term) and small business or small farm loans, and applies the 100-home-mortgage and 150-small-business thresholds to each of the prior two calendar years separately
  • Retail Lending Assessment Area (RLAA) Assembly Sheet — groups qualifying counties into whole-county assessment areas and records the grouping rationale
  • Delineation File Checklist — the data sources, cutoff dates, and sign-offs expected in an examination file
  • Three Worked Scenarios — a mortgage-heavy, a small-business-heavy, and a below-threshold branchless bank
  • Glossary — MSA/MD, county equivalents, assessment area, and the 2023 rule's new vocabulary

How To Use It: Inside the Branchless Delineation Lab

The Branchless Delineation Lab is a sequence of worksheets that switch on and off with your bank profile. Start with the Bank Profile Screen. Select whether your institution operates branches; when the branch count is set to zero, the facility-based assessment area panel switches off and the retail lending assessment area worksheet activates. That state change is the core lesson: without facilities there is nothing to surround, so delineation authority comes entirely from loan data.

Next, the County Trigger Tally lists every county where you geocoded originations. Enter counts for home mortgage loans and for small business or small farm loans separately for each of the prior two calendar years. Any county that clears 100 mortgages or 150 business loans in each of the two years flips its row to a trigger result, and the assembly sheet pulls it into a proposed retail lending assessment area automatically. Drop below the threshold in a later year and the row releases — the worksheet mirrors how the rule re-tests every cycle.

Finish with the Delineation File Checklist and save the outputs with your examination materials. If your totals stay below every threshold, complete the negative-screen page anyway: documenting that no county triggered is itself the deliverable. The kit keeps each county's tally tied to its dated source report so the file rebuilds cleanly next cycle.

Checklist

Before you call the delineation file done, confirm every line below. The first items establish that the rule applies and was applied correctly; the rest protect the file under review. Keep dated copies of the underlying loan reports; a trigger that cannot be rebuilt from source data is a finding waiting to happen.

  • Bank size confirmed: current-year asset thresholds applied, retail lending test applicability documented, and any compliance-date phase-in noted
  • Branchless status documented: no staffed banking facilities in operation, so no facility-based assessment area is delineated and all retail lending counts as outside any facility-based area
  • Two-year origination data pulled: closed-end home mortgage and small business or small farm loans geocoded to census tracts and rolled up to counties, with counts matching source reports
  • Trigger screen run: every county tested against the 100-mortgage and 150-business-loan thresholds in each of the prior two calendar years, including county equivalents such as parishes and independent cities
  • Counties included in whole, with every grouping decision recorded in writing; the facility-based prohibition on arbitrarily excluding low- or moderate-income geographies recorded as not applicable to a branchless bank
  • Re-test scheduled: annual screen calendared against the prior two calendar years, with a reminder to check for amendments adopted after the 2023 rule

Three Branchless Banks, Three Trigger Outcomes

The scenarios below mirror the patterns a branchless lender hits most often. Read them before completing your own tally: the differences turn almost entirely on loan category mix and county concentration, not on headcount or deposit strategy. Each outcome is legitimate under the rule as long as the worksheet trail supports it.

  • Mortgage-heavy internet bank: 160, 105, and 118 home mortgage loans in its three strongest counties in the older of the two prior calendar years, then 150, 110, and 125 the next year. Every county clears the 100-loan threshold in each of the prior two calendar years, and all lending sits outside any facility-based area, so all three counties are assembled into a single retail lending assessment area.
  • Small business lender: its largest county recorded 170 small business loans two years ago and 155 last year — clearing the 150-loan threshold in each of the prior two calendar years — while no other county reached 150 in either year. A one-county retail lending assessment area is required, and the remaining counties are documented as below threshold.
  • Below-threshold lender: 60 home mortgage loans and 40 small business loans in its strongest county in its best year — under half of either threshold even at peak. No retail lending assessment area is triggered; the negative-screen page in the checklist becomes the centerpiece of the file.

Related Tools and Guides

This kit pairs with the 2023 CRA Final Rule explainer and the compliance-date lookup: read what changed, pin your dates, then complete the worksheets to produce the delineation itself.

If your question sits one step earlier — whether the CRA applies to your charter at all — start with the Coverage Gate Scoping Kit. If you are already counting loans, the small business loan reportability checker helps you decide which files belong in the small business tally before the trigger screen runs.

This kit is part of Success's CRA practice suite, and its outputs are built to slot directly into the linked tools: the delineation file you assemble here pairs with the compliance-date lookup for your phase-in calendar and with the reportability checker for the loan files feeding your county tally.

Disclaimer

This kit is educational material for general planning purposes. It is not legal, compliance, financial, tax, or investment advice, and it does not predict how any regulator will evaluate a specific institution, delineation, or examination file. Community Reinvestment Act treatment depends on each institution's facts, the current rule text, and examiner judgment.

Thresholds, dates, and definitions referenced here come from the 2023 final rule and the agencies' regulations as published in the Electronic Code of Federal Regulations; those provisions can be amended. Confirm the current text for your regulator — OCC, Federal Reserve, or FDIC — and work with your compliance and legal teams before finalizing any assessment area delineation or examination submission.

Common Questions

Do online-only banks have CRA assessment areas at all?

Yes — under the 2023 rule, assessment areas come from lending rather than branches. A large bank without branches delineates retail lending assessment areas in any county where, in each of the prior two calendar years, its originations cross the rule's loan-count thresholds. Facility-based assessment areas apply only where there are branches to base them on.

What thresholds trigger a retail lending assessment area?

The screen is a per-year count, not a two-year total. The delineation definitions — 12 CFR 25.12 (OCC), 345.12 (FDIC), and 228.12 (Federal Reserve) — require at least 100 home mortgage loans or at least 150 small business or small farm loans in a single county 'in each of the prior two calendar years.' The more-than-half-outside condition attaches only where a bank has facility-based assessment areas, so for a branchless bank it is satisfied automatically.

What happens if no county meets the thresholds?

The bank delineates no retail lending assessment area for those counties. The operational task is to document the negative screen — the per-year counts for each of the prior two calendar years and the data cutoffs showing no county crossed a threshold — so the decision can be reproduced at the next examination.

Why does a facility-based assessment area not apply to a branchless bank?

Facility-based assessment areas are drawn around staffed banking facilities such as branches. An internet-only bank that operates no staffed facility has no location to build one from, so its delineation file rests entirely on retail lending assessment areas and the documentation behind them. A bank that keeps even one staffed banking office should map that facility separately before concluding it is fully facility-free.

How often do retail lending assessment areas get re-tested?

The trigger screen runs against the two preceding calendar years of originations, with the thresholds measured per calendar year, so the answer can change every cycle. Counties that fall below the thresholds release, and counties that cross them must be added — which is why the kit ties every tally to a dated source report.

Where does community development activity count if there are no branches?

Under the 2023 rule, the community development financing test is applied to a bank's entire footprint rather than being confined to assessment areas. A branchless bank's partnerships are evaluated on the bank-wide record, while retail lending is evaluated through the assessment area framework this kit addresses.
