If you receive 1099 income, taxes work a little differently than they do for traditional W-2 employees.

You’re responsible for reporting income from multiple sources, tracking your own deductions, and often paying taxes throughout the year. That flexibility is great—but it also creates more opportunities to make mistakes.

As a tax professional working with freelancers, creators, and small business owners, I see the same tax mistakes over and over again. Most of them are completely avoidable once you know what to look for.

Let’s break down the most common ones.

1. Forgetting to Report Investment Income

One of the most common mistakes is missing investment income forms.

If you have multiple brokerage accounts, crypto platforms, or investment apps, you might receive several different tax forms such as:

• 1099-DIV – dividends from investments
• 1099-INT – interest income
• 1099-B – stock or securities sales

The problem? People often forget about smaller accounts, older investment platforms, or accounts they rarely log into.

But the IRS receives these forms too. If the IRS gets a 1099-DIV or 1099-B that you don’t report, their system will flag the difference automatically.

Tip:
Keep a simple list of all your investment accounts so you know where to look for tax forms each year.

2. Misunderstanding Reinvested Dividends

This one surprises a lot of people.

If your investments automatically reinvest dividends, you still owe tax on them.

Many investors assume: “If I didn’t take the money out, I don’t owe tax on it.”

Unfortunately, that’s not how it works. Dividends are taxable when they are paid, even if they are automatically used to buy more shares.

Your 1099-DIV will show the taxable amount, and it must be reported on your tax return.

3. Not Reporting Cryptocurrency Transactions

Crypto has created an entirely new category of tax mistakes.

Some common ones include:

• Not reporting crypto sales
• Forgetting about transactions on old exchanges
• Assuming small trades don’t matter
• Not tracking gains and losses

The IRS treats cryptocurrency as property, which means every sale, trade, or conversion can trigger a taxable event.

For example:

• Selling crypto → taxable gain or loss
• Trading one crypto for another → taxable
• Using crypto to buy something → taxable

Even if you didn’t receive a tax form from the exchange, you are still responsible for reporting it.

4. Taking Incorrect Deductions

Another common mistake is claiming deductions that aren’t actually allowed.

For example, many freelancers try to deduct commuting costs. But commuting from your home to a regular work location is generally not deductible.

However, these are valid deductions if you qualify:

• Business mileage between job sites
• Home office expenses
• Software and subscriptions
• Business equipment
• Professional education
• Marketing and advertising

The challenge isn’t just avoiding bad deductions, it’s also not missing the good ones. A lot of freelancers actually overpay taxes because they forget legitimate deductions.

5. Forgetting to Pay Quarterly Taxes

This is probably the biggest mistake 1099 workers make. Unlike W-2 jobs, taxes are not automatically withheld from 1099 income. If you earn money as a:

• freelancer
• contractor
• creator
• consultant
• small business owner

…you are usually required to make quarterly estimated tax payments.

These are typically due:

• April
• June
• September
• January

If you skip these payments, you may face:

• penalties
• interest
• a large tax bill at the end of the year

Even if you pay everything at tax time, the IRS can still charge penalties for not paying during the year.

6. Assuming the IRS Only Knows About the 1099s You Receive

Another misconception is that you only need to report income if you receive a tax form. Not true.

You must report all income, even if:

• the client didn’t send a 1099
• you were paid via PayPal or Venmo
• it was a small side project
• it was cash

The IRS increasingly receives third-party reporting from payment platforms, so missing income can easily trigger notices later.
