A lien can indicate a business may not be in good financial standing because of unpaid debts. Learn how and why to do a UCC or tax lien search for KYB.

01
Overview

In brief: 

  • Searching for UCC or federal & state tax liens involves looking for legal claims against a business or business owner’s property due to unpaid debts
  • Lien searches are a component of Know Your Business (KYB) processes, as they can signal enhanced risk of onboarding a business that’s in financial trouble
  • Liens can be found at state Secretary of State (SOS) offices or state/county recorder’s offices, ordered directly from the IRS, or retrieved automatically from a software like Middesk when running business verification checks

Whether a business has UCC tax liens filed against them is a significant risk factor B2B onboarding for lendings and Financial Institutions (FIs). A business in debt could be at risk of losing property or other assets critical to its functioning, or have trouble getting additional financing if it doesn’t have enough collateral to offer to another lender. 

Determining whether a business you want to onboard as a customer has any liens filed against them is a critical top-of-funnel step in the Know Your Business (KYB) process. Lien information is made publicly available by the IRS and Secretary of State (SOS) offices, but it’s difficult to automate lien searches at scale if you onboard a lot of new businesses.

What is a UCC lien search?

A UCC lien search is the process of looking up whether an entity (a person or business) has any Uniform Commercial Code (UCC) liens filed against it. A UCC lien is a legal notice from a creditor laying claim to collateral from a borrower on a loan if the borrower defaults on the loan.

Basically, if a person or business takes out a loan and then later defaults on it, UCC liens determine the order in which creditors can seize the borrower’s collateral to repay the debt. A UCC lien can also indicate which assets are to be prioritized for seizure in the event of a default.

What is a federal or state tax lien search?

A federal or state tax lien search is a check to see if an entity has any tax liens filed against it by a federal or state government. These liens are documents allowing a federal or state government to lay legal claim to an entity’s assets if said person or business has unpaid taxes. 

In short, UCC liens are claims to collateral by private creditors when an entity owes a debt to them via a loan. Federal and state tax liens are claims to property by governments when an entity owes debts to them in the form of unpaid taxes. Businesses in the U.S. typically have liens filed against them by the IRS.

Why lien searches are critical for business underwriting

When it comes to KYB, a UCC or tax lien search isn’t so much about identity verification as it is about customer due diligence and risk management. An outstanding lien against a business could be a significant risk indicator, as it could signal a business is in debt and is in danger of losing assets if it doesn’t repay its debts. 

Why UCC lien searches are essential during onboarding

The assets being held as collateral could be critical to the business’s operations, which could be detrimental to you if you choose to onboard them. Collecting the data you need to perform due diligence and put together a lien data report is critical to mitigating your risk in these situations.

Even if the business is eventually able to deal with the lien by paying off its debts, an active lien could still be a risk factor in the meantime. It could hamper the business’s efforts to secure additional funding. 

It also signals to a lender that they aren’t first in line to collect collateral from the business if it defaults on its debts. The lender may not see any remaining collateral that they’re interested in, or they may fear that the business will run out of assets before it’s their turn to collect on what they’re owed.

In short, a UCC lien is a warning sign that the business won’t be able to fulfill its client or partner obligations in the near future. That might make the business too risky to start or continue a relationship with.

Why notification of a new UCC lien is essential for ongoing compliance

A business may be all clear of liens during onboarding, but what happens if they later have a lien filed against them? Do you want to wait for that business to tell you there’s a lien against them (because they likely won’t make that a priority). 

Instead, you should also set up ongoing monitoring for lien filing to get notified when there’s a change in the business lien status.

5 methods for how to do a UCC lien search

There are a few places where you can conduct a tax lien search or UCC search, and most are official U.S. government agencies. However, the level of government with which liens are recorded differs from state to state.

For some states, liens are recorded at the federal or state level, so searches for them don’t need to be quite as precise. For other states, liens are recorded at the county level, which can make searches trickier depending on how a lien was filed — you need to know in exactly which county the debtor lives or does business, or where the collateral property is actually located. So you may need to search in multiple places before you find an applicable lien.

To help make it easier, these are the 5 ways you can do a lien search in the U.S.

1. Use a dedicated lien search tool

Third-party tools like Middesk’s Business Underwriting solution, are able to pull business filing data — including UCC tax liens — directly from official (government) sources. They can also search multiple databases simultaneously, pulling additionally-useful business verification information that’s useful to other components of your KYB process, like EIN/TIN verification, watchlist status, and more.

This takes care of a lot of the heavy lifting in terms of determining exactly where the lien was filed. These tools also provide more flexibility in how liens can be searched for, including by businesses names, individual names, addresses, filing numbers, filing types, filing statuses, and so on.

2. Use a lien search API tool

While lien searches can be conducted manually, the fastest way to do a UCC or tax liens search is to use an automated tool. A solution such as an API can quickly aggregate data from multiple sources, saving time that would otherwise be used checking individual sources one by one. 

Typically, you would enter the legal name of the businesses you want to search for, and then specify you want to search for a lien.

3. Search business records at a state Secretary of State (SOS) office

Most businesses in the U.S. are registered at the state level, so their information will be recorded with a state SOS office. Each SOS office has their own online portal and database that allows for searching business filings to get information on businesses registered to operate in the state. This includes UCC liens and federal/state tax liens.

You can also try a UCC-11 search. This involves downloading a UCC-11 form – an official request for UCC information – from each state’s Secretary of State website (here’s an example of the one from New York). Then it requires filling out the form, sending it to the SOS office for that state, and waiting for documents to arrive.

This can be a slow process, and it often requires signing up for an account and/or paying fees.

4. Look for liens on a state or county recorder’s office website

Another place you can search for tax liens is at a state or county recorder’s office (or its website). This can be a complicated process, though, as where liens are recorded can differ depending on state law. 

Some states – such as Colorado, Mississippi, Illinois, and South Carolina – have centralized tax lien registries that simplify the search. In other states, however, tax liens are recorded at the county level. And which county a lien is recorded in can differ depending on things like whether the debtor is registered as a business or one of its owners. So the lien may be where the owner lives or where the business operates, or even where the collateral assets are located.

Again, this can be a painstaking process that may require paying money to get hard copies of documents (if this is necessary).

5. Get a list from the IRS via a Freedom of Information Act request

The IRS has an Automated Lien System (ALS) database that automatically collects and files tax liens from all 50 states as well as DC. It’s possible to get a copy of this database by submitting a Freedom of Information Act (FOIA) request to the IRS. This can be done online, by fax, or by mail, and they have clear Freedom of Information Act guidelines to follow to submit your requests properly.

Warning

As of January 1, 2023, there are no additional fees for requesting this information. However, the database doesn’t necessarily have all legal information related to federal tax liens, so the data could be incomplete or inaccurate. It’s also provided on a CD, which isn’t a very commonly-used medium these days, so you may have to find a device that can read the information.
