Onboarding your first 1099 contractor

The classification comes before the paperwork

No document can turn an employee into a contractor, so the test comes before the forms, every time.

The Department of Labor and Industry says it directly: tax forms the employer requires a worker to fill out or provides to a worker are not a factor and do not determine proper classification. A W-9 is a record of a decision, and the decision is made on the working relationship.

So open with the classification guide. Construction work runs the fourteen requirements, and everything else runs the five factors. Only a person who passes walks out of this page with a file.

Collect the W-9 before the first dollar moves

The W-9 gives you the name and taxpayer identification number the 1099 will need, and it arms the rule that follows.

The form's own instructions state the consequence: persons making certain payments must, under certain conditions, withhold and pay to the IRS 24 percent of the payments. The trigger that matters for a contractor is a missing or incorrect taxpayer identification number. With no W-9 on file, you may owe backup withholding on every payment, at 24 percent, from the first one.

Get the form before the first payment, not before the first filing season, and put the TIN against the invoices when they arrive. A mismatch you find in January is a year of withholdings you cannot collect retroactively.

Write the deal down before the work starts

In construction, a written contract is the law's requirement, with a deadline attached; everywhere else it is the factor the state will weigh.

The construction statute requires the contract to be signed and dated by both sides, fully executed no later than 30 days after work commences, and to identify the specific services. The payment basis is set by the same requirement: commission, per-job or competitive bid, and not any other basis. An hourly rate cannot be papered over.

Outside construction, the five factors weigh control and independence, and a contract that matches a genuine outside business is the cheapest evidence there is. The prohibited-activities statutes make requiring an employee to sign a misclassifying document its own violation, so write the deal that is real, not the deal that is convenient.

Pay a business, in the business's name

The payment mechanics are part of the classification, especially in construction, where two of the fourteen requirements live here.

The statute requires the business entity to submit invoices and receive payments for the services in the name of the business entity, and it says cash payments do not meet the requirement. A check written to the person, a payment app sent to a personal handle, or cash in hand all fail it.

Outside construction, the same mechanics are evidence on the five-factor side: mode of payment, who furnishes tools and materials, and control over the work. Pay per job against an invoice, from your business account to theirs, and the paper trail doubles as the classification file.

Check the trade's own licenses, and Minnesota's own quirks

A genuine contractor in a licensed trade carries the license, and the check is a ten-minute visit to the licensing board's list.

Construction trades answer to the Department of Labor and Industry, which licenses electrical contractors, residential contractors, remodelers, roofers, plumbing and mechanical contractors and more, and state law separately requires registration before performing building construction or improvement services. Cosmetology carries its own licenses and, in suite salons, its own structure rules. Food trucks carry a mobile food unit license from the Department of Health, and household goods movers need a MnDOT permit before operating.

The reason to check is not politeness: engaging an unregistered construction person is itself a violation, each day a separate one. The trade pages cover the ones this site writes about, and the DLI license list is the master index for the rest.

Minnesota Statutes 326B.701 requires anyone performing building construction or improvement services to register with the commissioner before performing them. — Minnesota Revisor of Statutes, retrieved 2026-09-29

Set the tax calendar on day one

The filing season is decided in the hiring week, by what you collect and what you keep.

Payments for services to a nonemployee count toward the 1099-NEC reporting threshold, $2,000 or more per person for payments made in tax years beginning after 2025, and the form is due to both the worker and the IRS by January 31. If you file 10 or more information returns in aggregate across the year, electronic filing applies. The filing guide walks the whole return.

Then keep the file. Construction law requires three years of classification documentation, ready on demand, and the same shelf life is the safe habit everywhere. The checklist page is the file list; keep it beside the review guide for the day anyone asks for it.
