The Classification Question Comes First
Before you worry about forms, you need to answer one question: is your virtual assistant an independent contractor or an employee?
For most VA relationships, the answer is independent contractor — but the IRS does not simply accept your label. The agency uses a multi-factor test that examines behavioral control, financial control, and the type of relationship. Misclassifying an employee as a contractor can result in back taxes, penalties, and interest dating back to the start of the engagement.
The IRS publication 15-A describes the three-category test. Key contractor indicators include: the VA sets their own schedule, provides their own tools, works for multiple clients, and is paid per project or invoice rather than on a payroll cycle.
For US-Based Contractors: The W-9 and 1099-NEC
If your VA is a US person (citizen or resident) operating as an independent contractor, you must:
- Collect a W-9 before or at the time of first payment. The W-9 captures their legal name, address, and taxpayer identification number (TIN or SSN).
- Issue a 1099-NEC by January 31 of the following year if you paid them $600 or more during the calendar year.
- File Copy A with the IRS by January 31 (same deadline as the contractor copy since 2020).
If a VA refuses to provide a W-9, IRS rules require you to withhold 24% of payments as backup withholding. Document the refusal and consult your accountant.
For International Contractors: The W-8BEN
If your VA is located outside the United States and is not a US person, collect a W-8BEN (for individuals) or W-8BEN-E (for entities). This form certifies their foreign status and exempts you from 1099-NEC filing obligations in most cases.
Keep the W-8BEN on file for your records. It does not get filed with the IRS — it is your documentation that you performed due diligence.
Note: Some countries have tax treaties with the US that reduce or eliminate withholding on certain types of income. If you are paying large amounts to an international VA, consult a CPA familiar with cross-border contractor payments.
The VA's Tax Obligations (What You Are Not Responsible For)
Independent contractors are responsible for their own taxes. That means your VA — domestic or international — pays their own self-employment tax, income tax, and any local obligations. You do not withhold anything from contractor payments.
For US-based VAs, self-employment tax is 15.3% on top of income tax. Many freelancers pay quarterly estimated taxes to avoid a large annual bill. This is their responsibility, not yours — but understanding it helps if a VA ever asks you to adjust payment timing.
Common Tax Mistakes Business Owners Make
Paying in cash or informal transfers without documentation. Every payment to a contractor should have a corresponding invoice and payment record. "Off the books" arrangements are not just a tax risk — they are unenforceable if a dispute arises.
Mixing contractor and employee treatment. If you require a VA to work fixed hours, use only your equipment, and follow your exact processes, the IRS may reclassify them as an employee regardless of what your contract says.
Failing to collect W-9s before year-end. Retroactively chasing W-9s in December is stressful. Add W-9 collection to your onboarding checklist and make it a payment prerequisite.
Forgetting state-level obligations. Several states (California, Massachusetts, New York) have stricter worker classification rules than the IRS. If you and your VA are both in one of these states, review your state's AB-5 equivalent or consult local counsel.
Using Payroll Software to Simplify Compliance
Platforms like Gusto, Rippling, or Remote handle 1099-NEC generation, W-9 storage, and filing reminders automatically. For business owners managing three or more contractors, the time savings justify the subscription cost.
If you use a managed VA service, the agency typically handles payroll classification and tax documentation for their VAs. Stealth Agents operates as the employer of record for their virtual assistants, which removes tax complexity from your side entirely.
