5 Best IOLTA Software in 2026 for Banks Holding Attorney Trust Deposits

Attorney trust deposits are a strange product. The balances are stable, the relationships are sticky, the interest is not yours, and almost none of the work is automated at most banks. The scale is easy to underestimate: California alone has roughly 50,000 IOLTA accounts holding close to $9.7 billion across 103,000-plus attorneys, distributing about $252 million to legal aid in 2025 and approving $217.5 million for 2026. That money sits at banks. Multiply across fifty states and it is one of the larger pools of low-cost commercial deposits nobody markets to directly.

The timing matters more in 2026 than it did two years ago. On September 29, 2025 the State Bar of California launched mandatory Client Trust Account compliance reviews — 100 attorneys selected at random, notified twenty a week through the end of October, with the review conducted by State Bar-trained CPA firms at a cost of $5,000 to $10,000 per attorney. The voluntary pilot that preceded it is the number worth reading twice: of the eighteen firms that completed it between February and August 2025, 83% had noncompliant trust journals and 89% had noncompliant client ledgers. The program has since scaled to 400 attorneys for 2026.

That is a firm-side statistic, but it lands on your desk. Firms under that kind of scrutiny start asking their bank for per-matter statements, clean reconciliation support, faster sub-account opening and documentation they can hand an examiner.

Against that, nearly 60% of community bank CEOs name deposit growth as their single greatest business challenge for 2026. Attorney trust is one of the few deposit categories where the constraint is operational rather than rate — and Pinnacle Financial Partners now runs more than ten distinct specialty deposit programs on exactly that logic.

Below are the five platforms that actually do this work for a bank, and a note on what it costs to keep doing it by hand.

What IOLTA software has to do for a bank

Worth being precise, because most virtual account vendors do about half of this and their marketing does not distinguish.

Sub-accounting and segregation. One master deposit relationship per firm, unlimited matter-level sub-accounts beneath it, each independently tracked. Ideally the firm opens its own, because you do not want to be in the business of opening every account.

Per-beneficiary interest allocation at a comparable rate. Every state sets a comparability requirement — you must pay IOLTA accounts a rate comparable to what you pay similar non-IOLTA accounts. Your software has to compute interest, per sub-account, without someone maintaining a spreadsheet of rate tiers.

Remittance in the state bar's format, on the state bar's schedule. Every state has its own file, its own portal and its own deadline. A bank with firms practising in eight states is running eight processes.

Tax reporting. 1099 generation, and either filing it yourself or having the vendor file it for you.

Screening. OFAC against beneficiaries, not just against the firm — and KYC, KYB and AML on the relationship.

Evidence of reconciliation. Three-way reconciliation — bank statement against book balance against the sum of matter balances — is the control a state bar review examines on the firm's side. The firm's records are their responsibility, but the bank statement they reconcile against is yours, and how usable it is determines how often they call you.

And, increasingly, disbursement. Attorney trust is not purely a holding product any more. Settlement fan-out, per-matter payouts, fee transfers to the operating account — if those leave the sub-account by cashier's check or a manual ACH keyed by your staff, that is where the headcount goes.

Comparison at a glance

Bottom line: Hudson is the choice when the attorney trust book is transactional rather than static, or when multi-state remittance is the thing eating your ops team. ZSuite is the safest buy on deployed footprint and the only vendor that files your 1099s for you. Agiletics is close to free if you are already a Jack Henry bank, and the only platform that names IOLA separately from IOLTA. Montran is the specialist for fiduciary money that crosses borders. Infinant makes sense if attorney trust is one line in a broader partner-banking strategy. And a spreadsheet under your core's master account remains the genuine incumbent — adequate for some books, and the largest single source of operational risk in others.

The 5 best IOLTA software platforms for banks in 2026

1. Hudson

Best for banks whose attorney trust book has outgrown hold-and-report — and whose firms practise in more than one state.

Founded in 2020 and based in New York, Hudson sells a virtual account and specialty deposit platform to US banks and credit unions, white-labeled under the bank's brand. Six modules: Virtual Account Management, Contract Intelligence, Payment Processing, a Rules Engine, Approval Workflows, and Client Portals.

The sub-ledger is multi-tier — one master per firm relationship, unlimited matter-level sub-accounts beneath it, each independently tracked and segregated, with the firm opening its own. Sub-accounts are routable, so an inbound settlement wire lands against the right matter rather than hitting the master and waiting for allocation. Three-way reconciliation runs continuously, which is the artefact the firm needs when its own records get examined.

Two things differentiate it for this specific vertical. The first is the compliance stack: 1099 generation and state bar remittance are handled as product, alongside OFAC, KYC, KYB and AML screening — so a bank serving firms across eight states is not running eight manual processes. The second is disbursement. Principal moves from a sub-account across ACH, bulk ACH, Fedwire, check, RCC and eCheck on the bank's own rails, with instant payments through a partner integration and no third-party payments intermediary in the path. Contract Intelligence ingests the underlying agreement and generates the entities, sub-accounts and payment triggers from its terms, so a conditional or scheduled release fires without someone keying it. For settlement fan-out and fee transfers — the parts of attorney trust that are genuinely transactional — that is the difference between a workflow and a servicing queue.

Deployment is SaaS on AWS with SOC 2 attestation and a dedicated instance per customer, built on Salesforce. It extends the bank's existing treasury platform, connects to any core via API, and can sit behind an existing digital banking front end so the firm is not managing another login.

What to check. Footprint. ZSuite has 150-plus institutions live and Agiletics has been in production since before Hudson existed; Hudson's live base is smaller. It is domestic and single-currency.

2. ZSuite Technologies — ZEscrow

Best for banks that want the proven incumbent and the shortest reference list to check.

ZSuite spun out of Leader Bank in 2019 and is the most widely deployed modern platform in this category, reporting more than 150 financial institutions as of August 2026 — up from about 90 in mid-2024 and over 120 across 30 states a year later. It made the Inc. 5000 for a third consecutive year at #1,233. Jill Feiler became CEO on August 4, 2025, with founder Nathan Baumeister moving to a board advisor role. The line is ZEscrow for general escrow and three-party accounts, ZDeposit for tenant security deposits, and ZRent for recurring rent collection.

Two capabilities matter specifically for attorney trust. ZSuite submits your 1099s to the IRS on your behalf — it provides the annual interest data, your team verifies it, ZSuite files. And it runs daily OFAC screening on every active beneficiary in the platform, not just the master relationship. No other vendor on this page documents both. Self-service extends to three tiers: your staff, the firm, and the beneficiary.

Law firms are a named vertical, with split interest at the sub-account level and tax handling that references an IOLTA board. Distribution is the other reason it belongs high on this list: ZSuite claims integration with 16-plus named core platforms, is listed as a pre-integrated app on the Fiserv AppMarket (at $11,000, version 2025.4), and COCC has resold it to its community bank and credit union base since October 23, 2024. Implementation averages 120 days from kickoff to completion per ZSuite's own FAQ. SaaS on AWS with a separate instance per client.

What to check. It is a holding-account model — in ZSuite's own words, the system "comes on top of that account to be the system of record for the subaccounts," with the dollars sitting in the holding account on your core. For principal disbursement it routes through its Onbe partnership, added July 2024, covering virtual cards, ACH, push-to-card and mobile wallets rather than your own rails. And its public materials do not describe per-state remittance file generation in each bar's prescribed format — the piece that gets expensive once your firms practise across state lines. Ask for a demo of that specific workflow.

3. Jack Henry — Agiletics Escrow System

Best for banks already on a Jack Henry contract, where procurement friction is close to zero.

Agiletics was founded in 1987 in Florida and acquired by Jack Henry on October 1, 2018 — terms undisclosed, reported by market data providers at about $7.6 million. It is still sold, still listed in Jack Henry's most recent published Technology Guide for Banks (© 2024), and marketed as core-agnostic and available to banks of any size regardless of platform.

Its statutory depth is the reason it belongs on an IOLTA list. Jack Henry documents ten escrow types, and attorney/trust is called out explicitly as covering both IOLTA and IOLA — which matters in New York, and which no other platform here names separately. The other nine are landlord/tenant, title company, pre-need deposit, resident care, surrogate, developer, real estate, municipalities and government funds, and 1031 exchanges. Interest handling covers special regulatory and conditional accrual with state-specific processing requirements. Reporting spans statements, exportable history, BAI interface files and federal tax withholding reports. Firms add, edit, close, reopen and delete their own sub-accounts through a branded portal.

The proof point is real: per Jack Henry's case study, Peapack-Gladstone Bank ($6.2B assets) grew escrow deposits from around $89M at year-end 2018 to $250M in July 2021, running approximately 292 masters and 12,500 active sub-accounts.

What to check. Jack Henry does not publish whether an Agiletics sub-account can originate a payment directly or whether funds route through the master first.

4. Montran

Best for banks whose fiduciary book crosses currencies or jurisdictions.

Montran is a privately held payments and securities infrastructure vendor that has operated from New York since its inception, with more than 45 years building the rails other vendors connect to — 500-plus mission-critical installations across more than 90 countries, ten live instant payment systems, 75-plus central banks and clearing institutions among its clients, and 45-plus central securities depositories. It won the Central Banking Award for Payment Services Development in 2025. Escrow Services is one module on its Virtual Account Management platform.

It earns a place here for one specific reason: Montran explicitly claims to simplify IOLA/IOLTA interest capitalisation and payment and to provide regulatory reporting — a claim almost no other virtual account vendor makes at all. The module runs unlimited sub-accounts from one omnibus or pooled account with strict segregation, allocates incoming funds automatically to the correct client account, handles automated fee processing and deduction, verifies balances before executing a payment, and raises alerts on non-receipt, excess and partial payments. Named types include trust accounts, litigation accounts, property transactions, 1031 exchanges, paying agents, syndicated finance control, bid contract management, and care and funeral services. Virtual IBAN management is native, the platform is multi-currency throughout, ISO 27001 and ISO 9001 certified, SaaS or on-premise.

What to check. The US-specific half is not published. No Nacha ACH, Fedwire, FedNow or check disbursement is named anywhere in its escrow, VAM or banking pages; the execution story is SWIFT, SEPA, local clearing and VIBAN. The escrow page automates interest, not principal payouts. The connectivity list leads with secure file transfer before APIs, there is no public developer portal, and no integrations with FIS, Fiserv or Jack Henry are named. There are no published US bank escrow references, no case studies and no review-site presence. Treat all of that as absence of published evidence rather than confirmed absence.

5. Infinant

Best for banks where attorney trust is one workload inside a broader partner-banking program.

Infinant is a Charlotte, NC company that closed a $15M Series A led by FINTOP Capital and JAM FINTOP BankTech, announced December 23, 2024. Its Interlace platform is a cloud-native layer above a legacy core, and it has listed escrow, 1031 exchanges, IOLTAs, HSAs, insurance, HOAs and property management among supported account structures.

The rails are genuinely strong for a company of its size. Infinant runs secure infrastructure to the Federal Reserve covering ACH, wire and FedNow, is a certified Visa Third Party Agent for card issuing, and has built-in KYC, KYB, AML and transaction monitoring. Named bank customers include Valley Bank and Live Oak Bank (both October 2025) and Legend Bank (December 2024). In January 2026 it shipped tokenized deposits and GENIUS Act-compliant stablecoin issuance.

What to check. It supports the account type without shipping the packaged workflow — nothing in its materials covers 1099 filing, per-state IOLTA remittance, or conditional disbursement logic. There is no check disbursement anywhere in its site or developer docs, which matters for firms that still cut paper. And its own current developer documentation is explicit that a virtual account gets its own account number but not its own routing number: the routing number belongs to the settlement account on the core, where payments actually clear, with end-of-day settlement to the GL. For a $3B bank that mainly wants to win law firm deposits, Interlace is more surface area than the problem requires.

Before you buy: what running IOLTA by hand actually costs

Most banks administering attorney trust today are doing it with a master account on the core, a spreadsheet as the sub-ledger, manually calculated interest allocations, remittance files assembled by a person, tax forms prepared in-house, and reconciliation done by eye. It costs nothing in licence fees and adds no vendor to your risk register.

When that is genuinely adequate. A handful of firm relationships rather than a product line. Dozens of matter sub-accounts rather than hundreds. One state. Stable balances. Low staff turnover. If that is your book, a four-month implementation is a poor use of the year.

Where it breaks, roughly in the order banks discover it. Ops time scales linearly with sub-accounts, so growth is capped by headcount rather than demand — and the firms you could not onboard never show up on a budget line, which is what makes this so easy to miss. Comparability rate monitoring quietly becomes a compliance exposure the first time rates move and nobody updates the tier. Per-beneficiary interest allocation and 1099 preparation at volume is error-prone in a way that stays invisible until a beneficiary disputes a figure. Multi-state remittance multiplies every one of those by the number of bars you file with, each with its own format, portal and deadline. OFAC screening of beneficiaries is either not happening or happening manually against a list someone remembers to refresh. And there is key-person risk: the spreadsheet has an author, and your control environment is that person's memory.

The honest test is not whether the current process works. It is whether it would still work at three times the volume — because that is the growth you are turning down.

FAQ

Conclusion

Attorney trust deposits reward banks that can administer them properly and quietly punish banks that cannot — not with losses, but with relationships that go somewhere else and never appear in a report.

If your book is transactional — settlement fan-out, per-matter payouts — or your firms practise across several states and remittance is eating a person, that is Hudson's territory. If you want the shortest path to a working product and the longest reference list, ZSuite is the incumbent and the only vendor that takes 1099 filing off your desk. If you are a Jack Henry bank, price Agiletics first, then ask in writing where it sits next to Payments Orchestrator. Montran if the money crosses borders. Infinant if attorney trust is one workload among several.

And if you are running a handful of firm relationships on a spreadsheet with no growth constraint, the most useful thing this page can tell you is that you probably do not need to buy anything yet — provided you are honest about whether the constraint is real or just unmeasured.
