Today's SMB Manual shows how a 1099 workforce can create six-figure tax exposure, why a signed contractor agreement may offer little protection, and how fixing the issue early can cost a fraction of what a buyer may deduct during diligence.

You may have started with 1099 workers because they were genuinely independent contractors. A technician had his own truck and tools, accepted jobs from several companies, and decided when and how to work. Five years later, the arrangement may look completely different. You set the schedule, the technicians wear your logo, drive your vans, use your software, and work only for you. The paperwork may still refer to them as contractors, but the working relationship has changed.

As the business grows, the gap between how workers are classified and how they actually work can become significant. It may first come to light when someone files for unemployment or workers' compensation. In other cases, it comes up during a sale, when a buyer reviews the employee census and several years of 1099s and sees that a company with 14 full-time workers has only 3 classified as employees.

A signed contractor agreement does not determine how the IRS classifies a worker. The IRS looks at how the relationship works in practice, such as who controls the work, who provides the equipment, whether the worker can make a profit or suffer a loss, and whether the relationship is ongoing and exclusive. If you control how the work is performed and the worker depends entirely on your company for income, the IRS may classify that person as an employee regardless of what the contract says.

If the misclassification was unintentional and you filed the required 1099s, Section 3509 allows reduced federal tax rates. Even then, the exposure can reach roughly 10.7% of contractor payments for each year the IRS can still audit. Six technicians earning $65,000 each represent $390,000 in annual payments. That works out to about $42,000 in potential federal liability for one year and roughly $125,000 over three years. State unemployment taxes, workers' compensation assessments, penalties, and interest can further increase the total.

The mistake is leaving the arrangement unchanged because moving workers to payroll adds roughly 10%-12% to labor costs. That saving can disappear when you sell the business. A buyer may view the 1099 workforce as a future liability, while the quality-of-earnings review adjusts EBITDA to reflect the payroll costs that should have been incurred.

For a $390,000 annual payroll, an additional burden of roughly $50,000 reduces EBITDA by the same amount. At a 4x multiple, that can reduce the purchase price by about $200,000, before the buyer requests an escrow or holdback to cover past exposure. A decision that saved $50,000 a year can therefore cost several times that amount when the business is valued.

The IRS Voluntary Classification Settlement Program allows qualifying businesses to move workers onto W-2 payroll and settle the federal exposure for 10% of one year's Section 3509 liability. The program generally does not add interest or penalties and does not require an audit of earlier years as part of the settlement.

On $390,000 of contractor payments, that could mean roughly $4,200 to resolve the federal issue, compared with about $125,000 of estimated exposure over three years if an audit finds the problem first.
