Plan contractor hiring in the United States

A direct U.S. contractor engagement should be scoped by the contractor's actual work location before the buyer approves the contract or the first invoice. The place where services are physically performed generally determines whether the income is U.S.-source, and the work state selects the state classification rules that sit beside the federal tests. A U.S. mailing address alone is too coarse. Record the state, any planned workdays abroad, and the entity receiving payment. The payer's lack of a U.S. entity or permanent establishment does not settle those questions. The usable sequence is location first, then separate federal tax, federal wage-law, and work-state reviews, followed by the tax-document duties those facts activate.

If the line is crossed

If federal common-law status changes from contractor to employee, the payer generally becomes liable for the Social Security and Medicare taxes and federal income tax that should have been withheld. Special section 3509 rates may narrow part of the calculation, while the full employer share remains due and intentional disregard can remove that relief. U.S.-performed employee services can be covered even when the employer and worker are foreign residents and the contract was made abroad. If the worker is also an employee covered by the Fair Labor Standards Act, minimum-wage, overtime, recordkeeping, and anti-retaliation duties apply. Establish FLSA coverage separately, then check any section 3121 exclusion or applicable totalization agreement before calculating the employment-tax exposure. The offshore contract label cannot perform any of those tests.

Form 1099-NEC

Nonemployee Compensation information return

Services physically performed in the United States are generally U.S.-source regardless of where the contract was signed, where payment occurs, or where the payer resides. A payment outside the United States by a non-U.S. payor falls within the foreign-transaction exception for services only when the remuneration is also foreign-source. The fixed offshore payer therefore cannot end the inquiry at its own residence. For tax year 2026, Form 1099-NEC generally reaches at least $2,000 paid in a trade or business for a nonemployee's services, subject to payee, entity, territorial, backup-withholding, and form-coordination rules. The $2,000 threshold is the 2026 figure and needs a 2027 check because inflation adjustments can begin then.

Issued by: Filed and furnished by the payer when its status and the transaction meet the reporting rules. The non-U.S.-payor definition tests ownership, income history, and specified U.S. branches; absence of a U.S. entity or permanent establishment does not complete it.

Timing: For a reportable 2026 payment, file with the IRS and furnish the recipient statement by 31 January, subject to the next-business-day rule. Classify the transaction and collect the supporting payer and payee documents during onboarding.

Form W-9

Request for Taxpayer Identification Number and Certification

Form W-9 gives a requester the U.S. payee's name, taxpayer identification number, and U.S.-status certifications when an information return may be required. It belongs in the payer's tax file and does not decide whether the relationship is employment. For reportable nonemployee compensation to a U.S. person, failure to provide a TIN in the required manner, or an uncured IRS notice that the TIN is incorrect, can trigger 24% backup withholding. The 30% Chapter 3 regime addresses payments to foreign persons. A reliable Form W-9 moves a documented U.S. payee into the information-reporting and backup-withholding analysis instead. A U.S. mailing address by itself does not supply that certification.

Issued by: Completed by the contractor and retained by the payer rather than filed with the IRS. Keep its payee-status and TIN data separate from the invoice and worker-classification record.

Timing: Collect it during onboarding when the payee is a U.S. person and an information return may be required. Resolve a missing or incorrect TIN before a reportable payment because backup withholding attaches to the payment.

Form SS-8

Determination of Worker Status for Purposes of Federal Employment Taxes and Income Tax Withholding

Form SS-8 gives the business or the worker a way to ask the IRS for a federal worker-status determination when the common-law facts remain genuinely unclear. The result governs federal income-tax and employment-tax return treatment. It does not decide Fair Labor Standards Act coverage or any state's classification test. The IRS also declines requests about true business-to-business relationships, including the wholesaler-to-retailer example in its guidance, and cases already being litigated between the worker and business. Use the form for an unresolved worker-versus-employee question after documenting the relationship, then keep the state and federal wage-law analyses on their own tracks.

Issued by: Either the service recipient or the worker can submit it to the IRS without the other party's agreement.

Timing: File when the federal common-law review remains uncertain and a determination is needed for return treatment. Continue the separate work-state and FLSA reviews.

Form 945

Annual Return of Withheld Federal Income Tax

Form 945 is the payer's return for nonpayroll federal income tax withheld from contractor payments. It becomes relevant when a reportable payment enters backup withholding, such as after a qualifying missing or incorrect TIN. The payer reports that withholding on Form 945 and keeps its deposits separate from payroll-tax deposits. Engaging a contractor does not by itself create the return. The trigger is the combination of a reportable payment and a backup-withholding condition. That distinction matters for an offshore payer because the Form 1099-NEC analysis has to be completed before the team can decide whether Form 945, an Employer Identification Number, and a withholding process are actually needed.

Issued by: Filed by the payer that withheld nonpayroll federal income tax, using the payer's own federal identifier rather than the payee's TIN.

Timing: Identify a backup-withholding trigger before payment, then report the withholding that occurred. Keep Form 945 deposits separate from any payroll deposits.

Form W-2 and the applicable employment-tax return

Employee wage statement and payroll tax reporting

When the relationship is employment, the payer leaves the nonemployee reporting track. Federal income tax is withheld from wages, employee wages are reported on Form W-2, and payroll taxes go on the employment-tax return that fits the employment. That return may be Form 941, Form 943, or Form 944, so the filing cannot be selected from the word contractor in the original agreement. The switch follows the legal status and the covered services. State payroll registration remains a separate work-state question. For a foreign payer, the immediate action is to establish its filing identity, obtain the employee information needed for payroll, and stop treating later contractor forms as a cure for earlier wage treatment.

Issued by: The employer furnishes Form W-2 and files the employment-tax returns. A responsible foreign organization needs its own Employer Identification Number even without a U.S. entity or permanent establishment.

Timing: Change the documents when the relationship is correctly treated as employment. The filing calendar depends on the federal return and state duties tied to the work location.

Texas supplies a narrow state example. It does not create a national invoice rule. A Texas seller's service can be taxable data processing when it enters, stores, manipulates, or retrieves the customer's data. A professional service does not become data processing merely because the contractor uses a computer as a tool. Characterise the actual deliverable, then locate customer use separately from the contractor's work location. Only the portion used in Texas is taxable, so service used entirely outside Texas is outside that taxable portion even when the contractor works in Texas. Customer certificates and another state's rules still need their own review.

Sources: Texas Comptroller, data processing services

What an invoice has to show

• Separate taxable data-processing charges from distinct nontaxable service charges in the Texas example

  When a Texas invoice combines taxable data processing with a distinct, identifiable nontaxable service that is commonly sold on its own, bill the taxable component separately and reasonably. If more than 5% of the fee represents taxable services and the invoice does not separate the charges, Texas treats the total charge as taxable unless documentation later establishes the nontaxable portion. This mixed-service billing rule applies only to Texas transactions. It is not a general U.S. invoice field. It matters only after the seller, service, and customer-use facts put the transaction inside the Texas rule.

Set invoice cadence, completion, acceptance, and the due-date calculation in the contract because no national net term was established. Illinois offers one conditional state example for contracts taking effect after 1 July 2024. Its Freelance Worker Protection Act applies at $500 or more in one contract, or aggregated with the same entity over the preceding 120 days, when the freelancer provides services in Illinois or the contracting entity is there. Covered engagements require a written contract that states compensation and the payment date or its calculation. Construction services, covered employees, and government counterparties are excluded, and the Act does not decide worker classification.

When invoices are settled

For a covered Illinois engagement, pay on the date stated in the contract or produced by its agreed calculation. If neither appears, payment is due no later than 30 days after the freelancer completes the services. Define completion and any acceptance step so an internal approval queue cannot silently move that fallback. The state remedy is material: a freelancer who is not timely paid final compensation may bring a civil action within two years after the amount was due and seek double the underpayment, injunctive relief, costs, and reasonable attorney's fees. This Illinois clock does not become a nationwide term for every U.S. contractor.

The currency on the invoice

Federal information reporting does not force a reportable contractor payment to be denominated or settled in U.S. dollars. When the amount is paid in another currency, the payer converts it into U.S. dollars on the payment date using the spot rate or a consistently applied reasonable spot-rate convention. That rule determines the amount on the federal information return. It does not prescribe the invoice currency, allocate conversion costs, or establish a customary commercial currency. Put the agreed currency, the party carrying conversion costs, and the valuation convention in the contract, then preserve the payment-date conversion record if Form 1099-NEC applies. A dollar reporting box is therefore an accounting output rather than a mandatory dollar price for the contractor's services.

Local currency rules

Screen the parties, ownership, service, and locations against the current OFAC program before release. All U.S. persons must comply, and a foreign payer must not cause or conspire to cause a U.S. person to violate sanctions or evade them. If property is blocked, the initial 10-business-day report ordinarily belongs to the U.S. person actually holding or controlling it. If an unblocked transaction is rejected because it would violate a prohibition, the U.S. rejector has its own 10-business-day report. Those duties do not attach automatically to the offshore payer merely because it initiated payment. FinCEN's funds-transfer recordkeeping rule likewise creates no government report by itself, although separate suspicious-activity rules can apply to a financial institution.

Using the contract, Form W-9, or Form 1099-NEC as the classification decision

A signed contractor agreement records the parties' label. Form W-9 records payee tax status and a taxpayer identification number. Form 1099-NEC reports a qualifying payment. None of the three decides worker status. The IRS weighs behavioral control, financial control, and the relationship as a whole, while the FLSA and the work state ask different questions. Build the status file from how the work will actually run: instructions, scheduling, tools, expenses, profit opportunity, permanence, economic dependence, the hiring entity's usual business, and the state-specific factors that apply. Revisit the file when operating practice changes, because a clean form packet cannot overcome a staff-style relationship.

Closing federal tax onboarding because the payer is offshore

A foreign payer does not receive an automatic Form 1099-NEC exemption from having no U.S. entity or permanent establishment. First locate the services. Work physically performed in the United States is generally U.S.-source regardless of the payer's residence or the place of payment. Then apply the regulatory definition of a non-U.S. payor, which asks ownership, branch, and income-history questions that the scenario label does not answer. Finally test the payee, entity, threshold, backup-withholding, and form-coordination rules. Record planned workdays abroad because they can change the sourcing analysis. The $2,000 threshold is the 2026 figure and needs a 2027 check because inflation adjustments can begin then.

Applying one worker test across every U.S. state

The United States has no single contractor test that resolves every obligation. Keep at least three decisions separate: IRS common law for federal employment tax, FLSA economic reality when federal wage-law coverage exists, and the rule attached to the contractor's work state and the state obligation at issue. California illustrates an ABC presumption with statutory exceptions and a demanding business-to-business route into Borello. Texas unemployment tax instead uses common-law direction or control and a 20-point guide whose weight changes with the service. Those examples do not stand in for another state. Record the work state before signature, name the law being tested, and refresh the conclusion before the contractor moves or the operating model changes.

Waiting until reclassification to establish the payer's federal filing identity

A foreign business that must report U.S. employment taxes or furnish employee tax statements needs an Employer Identification Number. The number is a federal filing identifier. It does not create a U.S. entity, permanent establishment, business license, or finding that the worker is an employee. A principal business created or organized outside the United States can apply by mailing or faxing Form SS-4, or by using the IRS international telephone process. Decide who owns the application as soon as employment treatment becomes a real possibility. A later payroll filing cannot use the contractor's taxpayer identification number in place of the payer's EIN, and delaying the application can leave required returns or tax payments without a processable identifier.
