A museum employee who sells illustrations on the side can be both an employee and self-employed. The paycheck comes from a job where the employer handles wage withholding; commissions from independently selling artwork come from a separate business activity. Having one source of wages does not turn the illustration sales into wages, nor does a small side business erase the employee relationship. The distinction affects recordkeeping and how taxes are paid, though the example alone cannot determine anyone’s filing obligations.
Two work relationships can coexist
The IRS says a person may be self-employed through a part-time business or gig work, including while also earning wages elsewhere. Its definition includes carrying on a trade or business as a sole proprietor or independent contractor, and being a member of a partnership carrying on a trade or business. The museum employee’s independent illustration sales fit the general idea of a separate business activity if they are conducted as a trade or business. Internal Revenue Service
Artists commonly combine creative work with other employment. The Bureau of Labor Statistics describes artists as selling work directly or through galleries and dealers, and says many artists hold another job to support their art careers. Its occupational description supplies context for the arrangement; it does not decide how any individual’s activity is classified for tax purposes. The key is to distinguish the museum’s employment relationship from the separate sales activity. Bureau of Labor Statistics
Withholding and estimated payments work differently
An employer generally withholds taxes from an employee’s pay. For self-employed income, the IRS explains that estimated tax is the method used to pay income tax and Social Security and Medicare taxes because there is no employer withholding those taxes for the worker. Self-employed people generally file an annual income tax return and pay estimated taxes quarterly, subject to the rules and their circumstances. A wage paycheck does not automatically handle tax payments on unrelated business income. Internal Revenue Service
That difference is about how money is paid in during the year, not a guarantee that a particular person owes an additional amount or must make a particular payment. The IRS directs people to use the Form 1040-ES worksheet to determine whether estimated payments are required. Because a person may have both wages and business income, the overall tax picture can include more than one stream; the broad description here does not calculate the outcome for the museum employee.

Keep the illustration business legible
The IRS says business net profit or loss is calculated by subtracting business expenses from business income. For the illustrator, that means keeping a record of sales and business expenses such as materials or other costs that belong to the work. The distinction between business income and expenses is necessary to figure net earnings; mixing the sales into a general account without records makes that calculation harder. Whether a particular cost qualifies for tax treatment depends on applicable rules and facts. Internal Revenue Service
A practical distinction helps: wages from the museum belong on wage records, while payments for independently sold illustrations belong in the business’s books. If the artist sells through a gallery or online marketplace, the records should still make it possible to trace receipts and associated expenses. This is ordinary bookkeeping guidance, not a conclusion about a specific deduction or reporting requirement. The IRS identifies Schedule C for reporting income or loss from a sole-proprietor business or gig work. Internal Revenue Service
The work arrangement does not answer every tax question
Being employed and self-employed at the same time is possible, but the labels do not settle every filing question. The IRS notes that self-employed individuals generally file an annual return and that filing requirements can depend on net earnings as well as other requirements. It also describes self-employment tax as Social Security and Medicare tax, distinct from income tax. The employee’s wages and the illustration activity must be considered within the full facts, rather than assuming one status controls both. Internal Revenue Service
The broader labor picture also helps explain why dual work is familiar in the arts: BLS says many artists hold another job and often spend time promoting and selling their work. Those observations describe the occupation, not a tax outcome or a prediction about any one artist’s income. For the museum employee, the useful takeaway is to maintain separate wage and business records and recognize that withholding from one job and payments on separate business earnings operate through different channels.
