1099 vs. W-2 structures — the misclassification line.

When a buyer retains the seller, the engagement is a 1099 contractor arrangement or a W-2 employee arrangement, and the distinction matters because the misclassification exposure — back taxes, penalties, interest, and potential liability for denied benefits — is assessed against the buyer. The decisive test isn't the contract label. It's the IRS control test (the substance behind Form SS-8): who directs how, when, and where the work is performed. If the buyer controls those, the relationship is W-2 regardless of what the agreement calls it, and a 1099 label on a W-2 reality is a liability waiting to be assessed.

§ 01 · The compensation bandsBy structure and intensity.

The 1099 bands top out around $200K+ for large or complex deals — above that, the IRS scrutinizes if the hours aren't well-documented. The hourly-cap rule of thumb on a 1099 is to cap monthly hours explicitly ("up to 10 hours a week"), because operational involvement of 20–40+ hours a month is the misclassification red zone. The tax rate on the compensation is identical either way — ordinary income up to 37% federal for both 1099 and W-2 — so the structure choice isn't about the seller's tax rate on the fees; it's about classification risk and the authority the engagement requires.

§ 02 · The control testSubstance over label.

The control test is the substance behind the classification, and it asks one question: who directs how, when, and where the work is performed? If the buyer sets the schedule, the methods, and the location, the relationship is W-2 — the contract label is irrelevant to the IRS. The practical decision criteria fall out of that. A 1099 fits when the work is advisory only, the seller controls the schedule and methods, the engagement is under 20 hours a month, and there's no staff management or P&L authority. A W-2 fits when there's staff management, P&L responsibility, a buyer-directed schedule, full-time or near-full-time engagement, or earnout-driven performance authority. The 20-hour threshold and the no-staff-no-P&L line are the practical proxies for the control test.

§ 03 · The earnout forces W-2The authority alignment.

The earnout-W-2 link is the place the classification decision most often gets mishandled, because the instinct is to keep the retained seller at arm's length as a contractor while still expecting them to hit performance targets. Those two are incompatible: performance authority requires operational control, operational control means W-2, and a 1099 that grants the operational control to hit the earnout has already failed the control test. The clean structure aligns the instruments — if the earnout depends on the seller's performance, the engagement is W-2, and the seller gets the authority the earnout assumes.

§ 04 · Documenting the choiceThe defensible engagement.

Whichever structure applies, the defensible engagement documents the substance, not just the label. A 1099 arrangement needs an explicit monthly-hours cap, advisory-only deliverables, and seller control over schedule and methods — and where the deal inherits an informal 1099-producer arrangement from the seller's pre-close operation, that arrangement needs formalizing before close, because informal contractor relationships carry the same classification risk plus weaker restrictive-covenant enforceability. A W-2 engagement needs the role, the term (1–3 years standard), and the authority documented to match the operational reality. The discipline throughout is that classification follows substance: the buyer who structures the engagement to match how the work actually happens avoids the reclassification assessment, and the buyer who labels around the substance inherits it.
