South Dakota IOLTA Accounts: Rules, Requirements, and How to Stay Compliant

TL;DR: South Dakota attorneys who hold client funds must maintain an IOLTA account under Rule 1.15 of the South Dakota Rules of Professional Conduct.

If you practice law in South Dakota, you already know that client funds are not your money. But knowing that and actually managing a compliant IOLTA account month after month are two very different things.

South Dakota IOLTA accounts are governed by Rule 1.15 of the South Dakota Rules of Professional Conduct, and the consequences of getting it wrong go well beyond a bounced check. A single recordkeeping error can put your license at risk. Yet most attorneys never received formal training on trust account management. You went to law school to practice law, not to run a mini-accounting department.

This guide cuts through the confusion. We'll cover exactly what South Dakota requires, how to open a compliant account, what your monthly reconciliation should look like, and where most attorneys run into trouble. Let's get into it.

What Is an IOLTA Account, and Do South Dakota Attorneys Need One?

An IOLTA (Interest on Lawyers' Trust Accounts) account is a pooled, interest-bearing trust account where attorneys deposit client funds that are either too small or held for too short a time to earn meaningful interest for the client individually. Under South Dakota Rule of Professional Conduct 1.15, attorneys are required to maintain a client trust account whenever they hold client or third-party funds in connection with a legal matter.

South Dakota attorneys who receive client funds must deposit those funds into either an IOLTA account or a separate, individual interest-bearing trust account for the client. The IOLTA option is used when the funds are nominal in amount or will be held for a short period, making it impractical to earn net interest for the client. The interest generated on IOLTA accounts goes to the South Dakota Bar Foundation, which funds legal aid and access-to-justice programs across the state.

The short answer: if you touch client money, you almost certainly need an IOLTA account.

What Are the South Dakota IOLTA Rules?

South Dakota's IOLTA requirements follow the core framework of ABA Model Rule 1.15, adapted through the state's own Rules of Professional Conduct and administered with oversight from the State Bar of South Dakota.

Key requirements include:

Separate accounts. Client funds must never be commingled with your firm's operating funds. Your trust account and your business checking account are entirely separate.

Eligible financial institutions. Your IOLTA account must be held at a bank or financial institution that has agreed to participate in the South Dakota IOLTA program and pay comparable rates of interest on trust accounts.

Prompt deposit. Funds received on behalf of a client must be deposited promptly. Sitting on a check is not acceptable.

Prompt disbursement. Once a client is entitled to funds, you must pay them out without delay.

Recordkeeping. You are required to maintain a trust account journal, individual client ledgers, and supporting documentation for every transaction.

Overdraft notification. South Dakota participating institutions are required to notify the State Bar if a trust account is overdrawn. This is one of the most serious triggers for a disciplinary investigation.

How to Open a South Dakota IOLTA Account

Opening a South Dakota IOLTA account is straightforward, but there are steps you can't skip. Here's what the process looks like.

First, choose a South Dakota Bar Foundation-approved financial institution. The institution must be on the list of banks that have agreed to remit interest to the SD Bar Foundation and comply with the overdraft notification requirements. Using a bank that isn't on this list isn't just inconvenient; it puts you out of compliance from day one.

Second, tell the bank the account is an IOLTA account. The account title should clearly identify it as a client trust account. Something like "[Your Name or Firm Name] Attorney Trust Account IOLTA" is standard.

Third, provide the bank with the South Dakota Bar Foundation's tax identification number. The bank needs this so it can remit the interest earned to the Foundation rather than to you. Your bank's commercial team should be familiar with this process.

Fourth, make sure the account is set up with overdraft notifications going to the State Bar. This is required under South Dakota's IOLTA rules, and your bank should set it up automatically when you identify the account properly.

Finally, document that the account has been opened and maintain that documentation in your firm records. If you're a new attorney or just starting your practice, doing this before you receive your first client retainer is a smart move.

What Records Does South Dakota Require You to Keep?

South Dakota's recordkeeping requirements under Rule 1.15 are specific, and they go well beyond just keeping your bank statements.

You need to maintain three core records at all times.

The trust account journal. This is a running log of every single transaction in and out of the trust account. For every deposit and disbursement, you need to record the date, the amount, the purpose, the client matter it relates to, and who the funds belong to or are paid to.

Individual client ledgers. Every client whose funds are in your IOLTA account gets their own ledger page. This ledger shows the running balance for that specific client. At any given moment, the sum of all individual client ledger balances should equal the total balance in your trust account.

Bank records and supporting documentation. This includes bank statements, canceled checks (or copies), deposit slips, and any wire confirmation records. You need to keep these for at least five years under South Dakota's rules.

These three records work together. The three-way reconciliation connects your trust account journal, your individual client ledgers, and your bank statement into one picture. If the numbers don't agree, there's an error somewhere that you need to find and fix before the month closes.

What Does an IOLTA Reconciliation Actually Look Like?

Reconciliation requirements are a lot easier to understand when you can see a real example. Before diving into the steps, we strongly recommend reviewing this example IOLTA reconciliation report on YouTube. Watching a reconciliation walk-through in real time will make every step below click into place far faster than reading alone.

Here's how the reconciliation process works for South Dakota attorneys.

Step 1: Reconcile your trust account journal to your client ledgers.Add up every individual client ledger balance. That total should exactly match the ending balance in your trust account journal. If it doesn't, you have a recording error somewhere. Find it before moving on.

Step 2: Reconcile your trust account journal to your bank statement.Compare every transaction in your journal to the transactions on your bank statement. Mark each one as you match it. Any transaction in your journal that isn't yet on the bank statement is an outstanding item, typically a check that hasn't cleared yet.

Step 3: Prepare your adjusted bank balance.Take your bank statement's ending balance. Add any deposits you made that haven't posted yet. Subtract any checks you issued that haven't cleared. The result is your adjusted bank balance.

Step 4: Confirm all three numbers match.Your trust account journal balance, your total client ledger balances, and your adjusted bank balance must all be the same number. That's the three-way reconciliation. If any one of the three doesn't match, there's an error to investigate.

South Dakota attorneys should complete this reconciliation at least monthly. Most bar disciplinary investigations related to trust accounting start because attorneys either skipped reconciliations entirely or fell months behind and never caught an error before it grew.

Common IOLTA Mistakes South Dakota Attorneys Make

Even careful attorneys make trust accounting mistakes. Here are the ones we see most often when working with law firms on their IOLTA compliance.

Commingling funds. Depositing a retainer into your operating account instead of your trust account, even by accident, is a serious ethics violation. It doesn't matter that you intended to move it later.

Paying fees from trust before they're earned. Your fee belongs in your operating account, not your trust account, and you can't move it there until you've earned it. Transferring money prematurely is another common commingling issue.

Forgetting to record every transaction. A $25 bank fee that you don't record can throw off your reconciliation and create a gap that looks like misappropriation. Record everything, every time.

Letting reconciliations lapse. Monthly reconciliation isn't optional. Skipping even one month can make errors compound. By the time you catch up, you may have a significant discrepancy that's hard to trace.

Using a bank that isn't IOLTA-approved. This is especially common for new firms. Always verify the bank is on the approved list before opening the account.

Frequently Asked Questions

Do all South Dakota attorneys need an IOLTA account?

Any South Dakota attorney who holds client funds or third-party funds in connection with a legal matter is required to maintain a trust account under Rule 1.15 of the South Dakota Rules of Professional Conduct. If the funds are nominal in amount or will be held for a short time, an IOLTA account is the appropriate vehicle. Attorneys who never handle client funds (such as those in purely transactional advisory roles where funds are never entrusted to the firm) may not need one, but this is the exception rather than the rule.

What happens if a South Dakota attorney's IOLTA account is overdrawn?

South Dakota-approved financial institutions are required to report overdrafts on IOLTA accounts to the State Bar of South Dakota. An overdraft is one of the clearest indicators of a potential trust accounting violation and can trigger a disciplinary investigation. Even if the overdraft was caused by a bank error or a timing issue, you need to resolve it immediately and document what happened. Proactive communication with the State Bar is almost always better than waiting for them to reach out first.

How often do South Dakota attorneys need to reconcile their IOLTA accounts?

South Dakota attorneys should complete a full three-way reconciliation of their IOLTA account at least once per month. This means reconciling the trust account journal to the individual client ledgers, and then reconciling the trust account journal to the bank statement. Monthly reconciliation is the standard that protects you in the event of a bar audit or complaint. Many firms complete it within a few days of receiving their monthly bank statement.

Can a South Dakota attorney keep their earned fees in an IOLTA account?

No. Your earned fees must be transferred out of your trust account and into your firm's operating account promptly after you've earned them. Keeping earned fees in the trust account is a form of commingling, which is a serious ethics violation. The flip side is also true: you cannot transfer fees from the trust account before they are earned. The timing of that transfer matters, and getting it right is a core part of clean trust accounting.

What is the difference between an IOLTA account and a non-IOLTA client trust account in South Dakota?

An IOLTA account is a pooled trust account where multiple clients' funds are held together, and the interest earned goes to the South Dakota Bar Foundation for legal aid programs. A non-IOLTA client trust account is an individual account established for a specific client when the funds are large enough or will be held long enough to generate meaningful net interest for that client. Attorneys are required to use reasonable judgment in determining which type of account is appropriate, based on the amount of the funds, the expected duration of the deposit, and the applicable interest rate.
