If 1099s Keep You Up at Night, You’re Not Alone: What Law Firms Really Need to Know

If there’s one topic that refuses to stay quiet in our world of legal bookkeeping, it’s 1099s.
Every January, law firms everywhere look up from their busy dockets and think:

“Wait… do we need a 1099 for this?”

If that’s you, take a deep breath. You’re in good company.

In a recent episode of Accountants Law Pod, we sat down with Jeff Cronin, Chief Strategy Officer at Zenwork (the team behind Tax1099), to talk about the messy, confusing, penalty-filled universe of 1099s—and what it means specifically for law firms. This blog is your plain-English, law-firm-focused guide to that conversation.

Why 1099s Matter So Much (Especially for Law Firms)

Here’s the un-fun truth: 1099s aren’t just paperwork. They’re a key piece of how the IRS closes the “tax gap” between what people should report and what actually gets reported.

When income is backed by third-party information reporting (like a 1099), voluntary compliance shoots up to the mid-90% range. When there’s no reporting? It drops dramatically. The IRS knows this, which is why they care so deeply about getting these forms right.

For law firms, the stakes are even higher:

• You’re constantly paying people on behalf of clients (medical providers, experts, investigators, mediators).

• You’re moving funds through trust/IOLTA accounts.

• You may be paying contractors domestically and abroad.

• You’re using modern payment tools like Venmo, PayPal, or credit-card processors.

Each of those decisions can come with 1099 implications, and potential penalties if you get it wrong.

The Foundation: W-9s and Vendor Information

If you remember nothing else from this blog, remember this:

You should not be paying people you don’t have proper information for.

In practice, that means:

• Collect a W-9 (or W-8BEN/W-8BEN-E for non-U.S. persons) before you pay a vendor, expert, or contractor.

• Make it part of your intake or onboarding process—not a last-minute January scramble.

• Store this information securely and in an organized way (ideally inside your accounting or 1099-filing system).

Why this matters:
If you ever get a CP2100/2100A “B-notice” from the IRS (a notice that the name/TIN combination doesn’t match IRS records), you need to show you made a reasonable effort to collect correct information. Having a W-9 on file is your safety net.

If you don’t have the right information and you don’t withhold when you should? That’s where you move into “you’re going to have a bad time” territory - backup withholding issues, penalties, and potentially very expensive conversations.

The Worst Mistake Isn’t a Math Error

Good news first:

• If the amount on a 1099 is wrong, you can usually fix it with a correction. Annoying, but manageable.

The real problem?

• Intentionally not filing when you know you should.

• Filing 1099s with missing or obviously invalid information (for example, sending most of your 1099s without any TINs).

That can trigger “intentional disregard” penalties, where the usual caps on penalties fall away. It’s the difference between a painful but finite bill… and a penalty that can grow into the six or seven figures for large payers.

If you’re reading this and realizing, “Oh… we may have just not done 1099s for a few years,” there is still a path forward:

• You can file prior-year 1099s (the IRS can accept several years back electronically).

• Voluntary disclosure and a clear, documented attempt to get into compliance is far safer than quietly hoping it never comes up.

The Law Firm Twist: Trust Accounts, Medical Providers & Experts

This is where it gets especially thorny for attorneys.

A few common scenarios we see:

1. Paying Medical Providers from Trust

“We paid that doctor from the client’s retainer, not from the firm. Do we still have to issue a 1099?”

Yes, in most cases you do.

If you’re holding client funds in trust and paying a medical provider, expert, or other service provider from the trust account, you are still the one making the payment. The client didn’t write that check—you did, on their behalf. That’s typically a 1099 situation.

Every year we see resistance around this:

• “But the client paid that.”

• “Can’t we just pull that 1099 back?”

• “The doctor doesn’t want a 1099.”

Unfortunately, preference doesn’t override tax law. If it’s reportable, it’s reportable. Whether or not the recipient likes the form, they still have to report the income they received.

2. Personal Injury & Complex Payouts

Personal injury firms tend to have some of the messiest 1099 footprints:

• Medical providers

• Experts and consultants

• Referral fees

• Physical therapy clinics

• Third-party services in settlements

On top of that, firms may negotiate discounts to medical bills at the end of the case, or structure fees in creative ways. That makes it even more critical to have a clear, repeatable process for determining:

• Who gets a 1099

• For what

• For how much

3. “But the Tax Person Told Me We Don’t Need One…”

We see this too: a law firm is told by a prior advisor that they don’t need to send 1099s in scenarios where the statute and instructions suggest otherwise - rent, certain medical and legal payments, and more.

This is where having a legal-aware bookkeeping and accounting team pays off. You need someone who doesn’t just know general small-business rules, but understands:

• How trust accounting interacts with 1099 requirements

• How case costs, advances, and reimbursements flow

• What’s unique about PI, family law, criminal defense, and other practice areas

Modern Payments, Old Rules: Venmo, PayPal, & 1099-K Confusion

Layer on top of all of this the rise of:

• Venmo

• PayPal

• Payment apps

• Online processors

• Prepaid and one-time payment cards

And now you have another question:

“If we pay someone through Venmo or PayPal, do we send the 1099, or does the platform send a 1099-K? Or both?”

Under the rules around 1099-K and “payment intermediaries,” platforms will increasingly be required to report more and more activity. Thresholds keep shifting, and there’s a real risk that perfectly personal, non-business transactions get caught in the net (like splitting dinner with a friend who pays you back via an app).

What this means for law firms:

• You need a clear policy on which payment methods you use for business vendors.

• When possible, pushing payments through properly configured merchant processors can move some reporting obligations off your plate.

• But the underlying rule still applies: what matters most is what the payment is for. If it’s reportable income, it has to be reported somewhere.

And if a client shows up with a 1099-K they believe is “wrong”? That becomes a conversation between the taxpayer, the IRS, and their tax advisor, not something the law firm can simply erase.

Paying Overseas Contractors: 1042-S & Withholding

Many law firms now use overseas help—virtual assistants, remote bookkeepers, or specialized contractors.

Those payments can trigger an entirely separate reporting universe: Form 1042-S (U.S. source income paid to non-U.S. persons), with mandatory withholding unless you have proper documentation and treaty-based exemptions.

Key points:

• Foreign vendors generally provide W-8BEN or W-8BEN-E, not W-9s.

• Depending on the nature of the income and the tax treaty, you may be required to withhold and remit taxes to the IRS.

• The recipient may have to file a U.S. return to claim a refund.

In many cases, the safest route is to pay foreign workers through a specialized payroll or contractor payment platform that handles the tax compliance and documentation for you. It’s one of those areas where “DIY” can quickly become more expensive than outsourcing.

“We Haven’t Been Doing This. Now What?”

If this all feels overwhelming, you’re not alone... and you’re not doomed.

Here’s a practical path forward:

1. Don’t ignore the problem.
   Once you know 1099s are an issue for your firm, doing nothing is the riskiest choice.

2. Start with the current year.
   Get a process in place now for collecting W-9s, tagging vendors correctly, and tracking payments throughout the year.

3. Look back strategically.
   With your accountant or bookkeeping team, identify prior years where you may need to catch up.

   • The IRS accepts several prior years electronically.

   • Voluntary filing typically leads to more favorable penalty treatment than getting caught after the fact.

4. Use the right tools.
   Software solutions like Tax1099/Zenwork exist for a reason: to handle volume, corrections, and electronic filing without you living inside a stack of red forms from the office supply store.

5. Get legal-specific bookkeeping support.
   Generalist bookkeeping can miss key law-firm nuances - trust payouts, retainers, expert payments, referral fees, and cross-border issues.
