When Tax Liens Stack on Top of MCA and UCC Filings

By MercResolution · Published 2026-07-18 · Updated 2026-07-21

When an IRS tax lien lands on a business already carrying MCA UCC filings, lien priority shifts, funding dries up, and fighting one creditor at a time backfires. Here is what to untangle first.

When a tax lien and a UCC lien sit on the same business, who gets paid first generally comes down to timing. A UCC-1 financing statement filed and perfected before the IRS recorded its Notice of Federal Tax Lien usually keeps priority in the collateral it already covered, while the tax lien moves ahead of almost everything filed afterward. But for a business carrying MCA-related UCC filings, there is a critical wrinkle: under the federal 45-day rule, receivables your business generates more than 45 days after the tax lien is filed generally fall under the IRS lien — even though the funder's UCC-1 came first.

That one rule explains most of what happens next. An MCA funder's collateral is your future revenue. Once a tax lien hits the public record, the funder knows the IRS is stepping ahead of it on every new dollar your business earns. So advances stop, default notices appear, and refinancing conversations go quiet — every creditor's behavior changes at once, usually for the worse.

The good news: lien stacks get untangled every day, and there is a logical order to it. Here is how priority works, why this combination is so corrosive to funding, and why one coordinated workout beats fighting one lien at a time.

I thought the funder and the IRS were two separate problems I could deal with one at a time. Then the funder declared a default over the tax lien, and I realized every creditor was reacting to every other creditor.

What a Tax Lien Does to a Business That Already Has UCC Filings

Your business took a merchant cash advance — maybe two or three — and each funder filed a UCC-1 covering your receivables, often broadened to "all assets." Then unpaid payroll or income taxes caught up, and the IRS recorded a Notice of Federal Tax Lien. Nothing physically changes that day, but three things happen on paper that matter enormously.

• The lien attaches to everything. A federal tax lien reaches all property and rights to property the business owns — equipment, inventory, receivables, bank funds — and extends to property acquired in the future.
• The lien goes public. The notice lands in records that funders, lenders, and monitoring services scan constantly. Assume every current creditor knows within days, not months.
• Contract defaults trigger. Most MCA agreements list a tax lien as an event of default — cover to strip discounts, accelerate the claimed balance, and collect aggressively.

If the lien is fresh, see our guide to the first 30 days after an IRS tax lien. This article focuses on what the lien does to the stack you already have.

Lien Priority Basics: First in Time, With a Federal Asterisk

The default rule in commercial law is blunt: first in time, first in right. For UCC liens, the filing date of the UCC-1 usually sets the pecking order among secured creditors.

Federal tax liens follow a modified version of the same idea. The lien technically arises when the IRS assesses the tax, demands payment, and doesn't get it — but against competing secured creditors, its priority generally runs from the date the notice is filed. So the rough map of a stacked business looks like this:

• UCC-1s perfected before the tax lien filing generally keep priority in the specific collateral they already covered at that point.
• The federal tax lien primes anything filed after it, and captures most property the business acquires going forward — subject to the grace window below.
• Later filings and unsecured creditors stand behind both.

State tax liens follow their own statutes, but the practical effect is similar: a public, priority-jumping claim every other creditor can see. One nuance: MCA agreements are typically written as purchases of future receivables rather than loans, yet funders still file UCC-1s — which is exactly why the next rule hits them so hard.

The 45-Day Rule: Why the Tax Lien Guts Your MCA Funder's Position

Here is the piece most owners never hear about until it wrecks their funding. Federal law gives creditors secured by revolving collateral — receivables, inventory, the things a business generates continuously — only a limited window of protection after a tax lien is filed. In general terms, a funder whose UCC-1 predates the tax lien keeps its priority only as to receivables that come into existence within roughly 45 days after the lien filing, or until the funder learns of the lien, whichever comes first.

After that window closes, the equation flips: new receivables generally sit under the federal tax lien ahead of the funder's claim, even though the funder filed first. The funder's "first position" quietly becomes a first position in collateral that is evaporating.

None of this is personal: the funder is watching its collateral degrade on a statutory timer — and a creditor in a degrading position is often willing to negotiate.

How Stacked Liens Choke Off Refinancing and New Money

Every serious lender starts underwriting with a UCC search and a public-records check. Two or three MCA UCC-1s plus a tax lien, and the file usually dies on the spot. To lend safely, a new lender needs a clear path to first position on collateral — and in a stacked business, there is no such path. Existing funders rarely subordinate voluntarily, and the IRS will only subordinate its lien through a formal application showing the government collects more with the subordination than without it. Our explainer on lien release, withdrawal, and subordination covers when each is realistic.

Meanwhile, the stack tightens. Funders still advancing stop. Some send UCC notices to your payment processor or customers to intercept receivables. The consolidation loan you were counting on is exactly the loan the stack now makes impossible — and the squeeze lands when cash flow matters most.

Untangling the Stack: The Order of Operations

Stacked liens come apart in a sequence, not all at once. The order matters because each step creates the conditions the next one needs.

Negotiating MCA Balances While the Tax Debt Gets Resolved

Owners often assume the tax lien freezes everything else until it's gone. The opposite is closer to the truth. A tax lien does not prevent you from settling MCA balances — it often improves your negotiating position, because the 45-day rule has already undercut the funder's claim to your future receivables. A funder weighing a discounted settlement against chasing collateral that now sits behind the IRS has a real incentive to deal.

The catch is coordination. A settlement schedule that ignores your tax resolution payment will collapse one or the other, so both agreements must be built from one honest cash-flow picture: what the business generates, what the IRS arrangement requires, and what is genuinely left for the funders. This is the core of professional business debt settlement and restructuring — in coordinated workouts, payment obligations are commonly reduced 50%+ and balances settled at 20-80% reductions, structured so the business keeps operating instead of liquidating.

One Stack, One Plan

Fighting a lien stack one creditor at a time is how owners end up robbing the tax plan to feed a funder. The stack is one problem with several heads, and it needs one plan: a mapped priority picture, a stabilized tax resolution, coordinated MCA settlements, and a cleanup of the public record. For most stacked businesses, that workout is the realistic alternative to a Chapter 11 filing — faster, quieter, far less expensive. Our comparison of debt-relief approaches lays out the trade-offs plainly.

Frequently Asked Questions

Does an IRS tax lien beat a UCC lien?

Not automatically. A UCC-1 perfected before the Notice of Federal Tax Lien was filed generally keeps priority in the collateral it already covered. But the tax lien primes later filings and most after-acquired property, and under the 45-day rule it generally takes priority in receivables generated more than 45 days after the lien filing — which is why it effectively overtakes MCA funders whose collateral is future revenue.

Can I settle my MCA debt while I have a tax lien?

Yes. A tax lien does not bar settlement of MCA balances, and it often strengthens your position, because the funder's claim to your future receivables weakens once the lien's 45-day window runs. The key is coordinating the settlement schedule with your tax resolution payments so one agreement doesn't break the other.

Why did my MCA funder stop advancing after my tax lien was filed?

Two reasons. Contractually, most MCA agreements define a tax lien as an event of default, which lets the funder halt advances and accelerate collection. Economically, the federal 45-day rule means receivables generated after that window sit under the IRS lien ahead of the funder's claim — so every new advance would be secured by collateral the funder may never reach.

Can tax debt and business debt be worked out together?

Yes, and they usually should be. Both draw on the same cash flow, so a plan built creditor-by-creditor tends to overpromise and collapse. A coordinated workout stabilizes the tax side first — the IRS has levy power the others lack — then negotiates the commercial debts to fit the remaining budget, all sized from one realistic cash-flow picture.
