What New Entrepreneurs
Get Wrong Their First Year

In 2026, with more platforms issuing tax forms and income being tracked more closely,
understanding the basics is no longer optional. Here is what new side hustlers commonly get
wrong in their first year and how setting up your business properly can help you avoid costly
mistakes.

Mistake 1: Thinking Side Hustle Income
Is “Extra” and Not Fully Taxable

One of the most common misconceptions is that side hustle income is somehow different from
regular income. In reality, money earned from freelancing, online sales, consulting, content
creation, or local services is taxable, even if it is not your main job.

If you receive payments through platforms like payment processors, marketplaces, or freelance
sites, that income is typically reported to the IRS. Even if no tax form arrives, you are still
responsible for reporting it.

Mistake 2: Not Understanding 1099 Income

Many new entrepreneurs are surprised when they receive a 1099 form. Unlike a W-2 job, taxes
are not withheld from 1099 income. That means the responsibility to set aside money for taxes
falls entirely on you.

This income is usually subject to both income tax and self-employment tax, which covers Social
Security and Medicare. Without planning, this can result in a much larger tax bill than expected
at filing time.

Mistake 3: Ignoring Estimated Quarterly Taxes

Another major mistake is assuming taxes are only paid once a year. In many cases, side
hustlers are required to make estimated quarterly tax payments if they expect to owe a certain
amount in taxes for the year.

Skipping these payments can lead to penalties and interest, even if you pay everything by the
annual deadline. Many first-year entrepreneurs do not realize this requirement until after they
have already missed multiple quarters.

Mistake 4: Assuming Everything Is a Write-Off

Write-offs are often misunderstood. While business deductions can reduce taxable income, they
must be ordinary, necessary, and directly related to the business.

Common examples of incorrect assumptions include deducting personal meals, clothing that
can be worn outside of work, full home expenses without qualifying for a home office, or
personal subscriptions that are only loosely connected to the business.
Taking aggressive or unsupported deductions increases the risk of audits and penalties.

Mistake 5: Mixing Personal and Business Finances

Using one bank account for everything is convenient, but it creates problems at tax time. Mixing
finances makes it difficult to track income, expenses, and deductions accurately. It also weakens
your ability to prove that certain expenses are truly business related.

Clear separation is one of the simplest ways to stay organized and reduce stress during tax
season.

How Proper Business Formation Helps Avoid These Problems

Forming a legal business entity creates structure around your side hustle. It helps clarify what
income belongs to the business, what expenses are deductible, and how records should be
kept.

A properly formed business also makes it easier to open a dedicated bank account, track
income for estimated taxes, and work with accountants or tax professionals if needed. Most
importantly, it reduces the risk of mistakes that lead to penalties or audits.

How Inc Authority Helps New Entrepreneurs

Inc Authority helps side hustlers take control of their business from the start. From LLC
formation and EIN services to compliance support, Inc Authority simplifies the process of setting
up a legitimate business structure.

For new entrepreneurs, having the right foundation can mean fewer surprises at tax time,
clearer financial records, and greater confidence as income grows. If your side hustle is earning
money in 2026, taking the time to set it up properly can save you far more than it costs.
