Avoid the Pitfalls of Adding Extra Icome



Earning extra income feels great until tax season arrives. A second job, freelance project, or growing side hustle can change how you're taxed in ways many people don't expect. Here are several rules to understand that will help you avoid the tax pitfalls of adding extra income.

Know whether you're an employee or independent contractor

Potential tax pitfalls: Many contractors and freelancers assume they're being taxed the same way they are at their day job. Then tax season arrives and they discover no one was setting aside money for Social Security, Medicare, or income taxes. In some cases, workers are even surprised to learn they were classified differently than they expected.

What you can do: Before accepting additional income, ask how you'll be paid and whether you’ll receive a Form W-2 or Form 1099. A short conversation upfront can prevent a much longer conversation when you prepare your tax return.

Employee income isn’t always simple

Potential tax pitfalls: Your employer withholds Social Security and Medicare taxes from your paychecks, which makes payroll taxes feel largely automatic. The problem starts when you add a second job or other side income. Each employer calculates withholding as if it's your only source of income, which can leave you short when everything gets added together on your tax return. Some workers may also receive tax forms other than a traditional W-2, creating another opportunity for confusion.

What you can do: Review your withholdings whenever you add a new income stream. A quick check during the year is much easier than finding out in April that your paycheck withholding wasn't keeping pace with your total earnings.

Contracting income means more responsibility

Potential tax pitfalls: Receiving a 1099 often feels very different from receiving a paycheck because no taxes are being withheld along the way. You're responsible for both sides of Social Security and Medicare taxes, which can make the final tax bill larger than expected. Mixing business and personal spending can also make it harder to identify expenses that could reduce taxable income.

What you can do: Keep business income and expenses separate from personal spending, whether that means opening a dedicated account or tightening up the one already in place. And if additional income becomes regular, build estimated tax payments into the routine instead of treating them as a year-end problem. A quick estimate during the year can help decide whether quarterly payments make sense.

Extra income can create new opportunities, but it also introduces new tax responsibilities. A little planning now can help keep more of what you earn and prevent unpleasant tax surprises later. Call if you have questions about your extra income.

Common Tax Questions

Here are several common tax questions and their answers. But like most things, there can be exceptions, so if in doubt always ask for help.

Is money earned through Venmo, PayPal, or Cash App taxable?

It depends on why you received the money. Payments from friends for splitting dinner or reimbursing expenses are not taxable. However, money received for selling goods or providing services is generally taxable income and may be reported to the IRS on Form 1099-K.

Do I have to pay taxes if I sell items online?

Maybe. Selling personal items for less than you originally paid generally doesn’t create taxable income, although the sale may still be reported to the IRS. If you sell items for a profit, the gain is usually taxable and should be reported on your tax return.

Can I deduct expenses for working from home?

Employees cannot claim a federal deduction for home office expenses. Self-employed workers may qualify if part of their home is used regularly and exclusively for business purposes. The deduction can include a portion of rent, utilities, insurance, and other eligible costs.

Is cryptocurrency taxable?

The IRS treats cryptocurrency as property, not currency. Selling crypto, trading one cryptocurrency for another, or using crypto to purchase goods and services can all create gains or losses that must be reported on your tax return. Even receiving cryptocurrency as payment, mining rewards, staking rewards, or certain promotional incentives may be taxable and must be reported on your return.

Is my tip income taxable?

Tips are still considered taxable income and must still be reported. However, under the One Big Beautiful Bill Act, many workers in occupations that customarily receive tips can claim a federal income tax deduction for qualified tip income through 2028. To qualify for the deduction, tips must be reported on Form W-2, Form 1099, or other approved reporting methods, and the worker must be employed in a qualifying occupation designated by the IRS. The deduction is limited to $25,000 per year and begins phasing out for higher-income taxpayers. Social Security and Medicare taxes still apply.

How much of my overtime pay is deductible?

Under the One Big Beautiful Bill Act, workers may deduct the overtime premium portion of qualified overtime pay through 2028. In a typical time-and-a-half situation, only the extra half-time portion is deductible, not your entire overtime paycheck. For example, if you normally earn $20 per hour and are paid $30 per hour for overtime, only the additional $10 premium qualifies. The deduction is capped at $12,500 annually ($25,000 for joint filers) and phases out at higher income levels. Social Security and Medicare taxes still apply.

Please call to schedule a tax planning session so you can be prepared to navigate around any potential tax surprises you may encounter on your 2026 tax return.
