When your US business should bring in outside experts, and how to hire them without tax or contract surprises

Picture a founder from Copenhagen whose US subsidiary has grown to eleven people. Sales are strong, and she spends every evening on things she does not know how to do: a Texas lease, a health plan, a pricing change for American distributors. We hear versions of that story every month, usually from owners who treat outside help as a luxury. In the US it is often the cheapest way to run a company, because the market for specialists is deep and you can buy exactly the hours you need.

Six moments when outside help pays for itself

Most companies do not need a consultant all the time. They need one at specific turning points, and missing those points is where the expense comes from.

1. Before you commit to a structure. State, entity type, tax classification and who owns what are hard to unwind. An hour with someone who has seen a hundred European structures beats a year of fixing one. Our overview of entering the US market lists the decisions that come first.
2. When a regulator writes to you. An IRS notice, a state sales tax audit letter or a request for evidence from USCIS has a deadline and a vocabulary. A specialist reads it in minutes.
3. When you hire your first American employee. Payroll registration, withholding, workers' compensation, benefits and the employee handbook all arrive at once.
4. When growth outruns your systems. Bookkeeping that worked at $200,000 of revenue often breaks at $2 million. So do pricing, inventory and reporting.
5. When you need a skill for a project, not a career. A website relaunch, a trade show, a product certification, a software migration. You want the expert for three months, not three decades.
6. When you need an independent view. Banks, investors and buyers trust numbers more when someone outside the company has looked at them.

The common thread: buy expertise when the cost of a wrong decision is high and the decision is rare. For the routine work you do every week, building the skill in house usually wins.

Who is licensed for what

Europeans are often surprised by how open the US consulting market is. Anyone can call themselves a business consultant. A few fields, however, are protected by law, and the difference matters when something goes wrong.

The immigration line deserves attention from Europeans in particular. In several European countries a notary is a senior legal professional. In the US a notary public witnesses signatures, nothing more, and USCIS states plainly that notaries cannot represent you in immigration matters. For visa work we always work with the attorneys on the firm's team.

Our guide on finding good US tax advisors and attorneys explains how to check a licence before you sign.

Start with the free help America offers

Before you pay anyone, look at what the federal government already funds. The Small Business Administration supports a network of resource partners in every state.

• SCORE mentors, many of them retired executives, offer area-specific advice at no cost.
• Small Business Development Centers provide individual advising and training for existing businesses and founders: access to capital, business planning, operations, finance, personnel, marketing, exporting and sales.
• Women's Business Centers provide free to low-cost counseling and training.
• Veterans Business Outreach Centers, run by 31 organizations under an SBA cooperative agreement, serve entrepreneurs from the military community.

These advisors will not file your tax return or draft your contracts, but they are excellent sounding boards for a business plan, a first marketing budget or an introduction to local lenders. We send clients to their local SBDC often. Think of them as the first step, and pay for specialists when the question becomes technical.

Consultant or employee: the question the government asks

A consultant who works like an employee is treated like one, and the employer pays the bill. Three different tests can apply to the same person.

The IRS: control of the relationship

For federal employment taxes, the IRS looks at the entire relationship and the extent of the right to direct and control the worker, grouped into three categories: behavioral control (do you control how the work is done?), financial control (do you control the business side, such as how they are paid, whether expenses are reimbursed, who provides tools?) and the type of relationship (written contracts, benefits, permanence). If you treat an employee as a contractor without a reasonable basis, the IRS says you may be liable for the employment taxes for that worker. A business or worker can ask for an official ruling on Form SS-8, which the IRS says may take at least six months. The Voluntary Classification Settlement Program lets a business reclassify workers as employees going forward with partial relief from federal employment taxes.

The Department of Labor: economic reality

For minimum wage and overtime under the Fair Labor Standards Act, the question is whether the worker is in business for themselves or economically dependent on you. The Department of Labor has stopped applying its 2024 rule in investigations and on February 27, 2026 published a proposal to replace it with an analysis built on two core factors, control over the work and the opportunity for profit or loss, plus skill, permanence and whether the work is part of an integrated unit of production. The comment period closed on April 28, 2026. As of today no final rule has been published, so the courts' economic reality case law governs.

The states: sometimes stricter

States apply their own tests for unemployment insurance and state wage laws. California's ABC test is the best known: the worker is a contractor only if they are free from your control, the work is outside the usual course of your business and they are customarily engaged in an independent trade of the same kind. All three conditions must be met.

In practice, a genuine consultant has their own company, several clients, sets their own hours and methods, invoices for a defined result and carries their own costs. If your "consultant" has a company email address, a fixed weekly schedule and one client (you), talk to us about hiring an employee instead.

The tax paperwork for paying consultants

Paying an outside expert creates reporting duties for your company. The rules depend on whether the consultant is American or foreign and where the work is done.

A US consultant

Ask for a Form W-9 before the first payment, so you have the consultant's name and taxpayer number. If your business pays a non-employee for services, you report it on Form 1099-NEC. The threshold changed with the One Big Beautiful Bill Act: for payments made before 2026 it was $600, for payments made in 2026 it is $2,000, and the IRS will publish inflation-adjusted figures for later years. Payments to attorneys for legal services are reported on Form 1099-NEC as well.

A foreign consultant

Many of our clients use designers, developers or advisors in Europe. Here the decisive question is where the work is physically performed. The IRS's Publication 515 states that the place where personal services are performed determines the source of the income, regardless of where the contract was made, where payment is made or where the payer lives. Work done in Barcelona for your Texas LLC is foreign-source income for the Spanish consultant, and the US does not tax it.

Collect a Form W-8BEN or W-8BEN-E anyway. Publication 515 says foreign persons who provide a valid Form W-8 are exempt from backup withholding and Form 1099 reporting; without it, the payer may have to presume the payee is a US person. If the foreign consultant comes to the US and performs services here, the picture changes: pay for independent personal services performed in the US by a nonresident is subject to 30 percent withholding unless a treaty exemption is claimed, usually on Form 8233. Our page on US withholding tax by type of income has the treaty detail.

What belongs in the consulting agreement

American business runs on written contracts, and a consulting agreement is where most of the risk lives. These are the clauses we read first.

• Scope and deliverables. What exactly will be delivered, by when, and what counts as done. Vague scope is the number one source of fee disputes.
• Fees and expenses. Hourly, fixed price or monthly retainer; who pays travel; when invoices are due; what happens to unused retainer hours.
• Ownership of the work. This is the clause Europeans miss most often. Under the US Copyright Act, work created by an independent contractor belongs to the contractor unless it falls into a short list of commissioned categories and both parties sign a written agreement calling it a work made for hire. Software, designs, reports and websites often fall outside that list. The safe route is an explicit assignment of all rights, and a transfer of copyright is only valid if it is in writing and signed. Our page on protecting intellectual property in the US covers patents and trademarks too.
• Confidentiality. Your customer lists, pricing and plans, protected during and after the engagement.
• Independence. A clause stating the consultant controls their methods and hours, supplies their own tools and may work for others. It does not decide the classification, but it should describe the reality.
• Limitation of liability and insurance. Professional consultants usually cap their liability; you may want proof of professional liability coverage.
• Termination. Notice period, payment for work done, handover of files.
• Governing law and venue. Which state's law applies and where disputes are heard. For a Texas company, Texas law and a Texas venue are the natural choice.

Choosing, pricing and managing an outside expert

A good consultant is not cheap, and in the US the market sets the price openly. The Bureau of Labor Statistics counted 1,077,100 management analyst jobs in 2025, with a median annual pay of $101,860 in May 2025, and 14 percent of management analysts are self-employed. The occupation is projected to grow 10 percent from 2025 to 2035, much faster than average. Independent experts who carry their own overhead, insurance and unbilled time charge accordingly.

Three fee models dominate:

Before signing, we tell clients to do four things: check the licence where one exists, call two references from companies of similar size, ask for a written proposal that restates your problem in the consultant's own words, and agree on one person inside your company who owns the relationship. That person sets priorities, receives the reports and decides when the engagement ends. Consultants who report to everyone end up working for no one.

Finally, plan the handover from the first day. The best engagements leave something behind: a process documented, a team member trained, a system that runs without the consultant. If you are still calling the same expert for the same task after two years, it may be time to hire, and our note on an employment contract without a US presence shows how that can work even before you have an office.
