The Short Answer

If you earned money from a side hustle this year — freelance work, driving for a rideshare app, selling on an online marketplace, tutoring, whatever it is — the IRS generally considers that self-employment income, and it gets reported differently than your W-2 paycheck. Most people filing with side hustle income for the first time do best with tax software that walks them through Schedule C, calculates self-employment tax automatically, and flags deductible business expenses they might otherwise miss. TurboTax Self-Employed has historically been one of the most thorough options for this specific situation, though it’s not the cheapest.

Who This Is For ✅

  • ✅ Someone who received a 1099-NEC or 1099-K this year and has no idea what to do with it
  • ✅ A W-2 employee who picked up freelance or gig work on the side and needs to file both types of income correctly
  • ✅ A first-time side hustler trying to understand what expenses they can potentially deduct — mileage, home office, supplies — without getting into trouble with the IRS
  • ✅ Someone who filed their taxes on their own before but is now dealing with self-employment income for the first time and wants to know which software handles it well

Who Should Skip This Guide ❌

  • ❌ Someone whose side hustle has grown into a full-time business with employees, inventory, or complex depreciation — that situation typically warrants working with a CPA directly
  • ❌ Anyone dealing with a tax audit, back taxes, or an IRS notice — this guide covers standard filing, not tax resolution; consult a tax professional for those situations
  • ❌ People whose only income is a W-2 with no side income whatsoever — you’d be better served by a simpler tax filing guide
  • ❌ Anyone looking for guidance on business entity tax filings (S-Corp, LLC taxed as a partnership, etc.) — those situations go beyond what general tax software guides can responsibly cover

How Marcus Evaluated These

I didn’t grow up knowing what a Schedule C was. When I started picking up side income in my late 20s — some consulting work, some odd jobs — I genuinely had no idea I was supposed to be tracking anything or that I’d owe self-employment tax on top of regular income tax. The IRS wasn’t particularly forgiving about my ignorance, and that tax bill stung. So when I look at tax software for side hustlers, I’m specifically looking at whether the product would have helped someone like me — someone with no background in accounting — actually get this right without hiring a professional.

For this guide, I evaluated tax software options based on how clearly they handle Schedule C income, whether they prompt users to enter deductible business expenses (rather than making you know to ask), how they handle estimated quarterly tax guidance, and what they actually cost at the self-employed tier. I also considered how each platform handles the 1099-NEC and 1099-K import process, since those are the forms most side hustlers are dealing with. My focus is on software that’s genuinely useful for someone juggling a day job and a side hustle — not someone running a sophisticated operation. Rates and pricing change frequently; verify current pricing directly with each provider before filing.

Top Picks: Marcus’s Recommendations

Pick Why Marcus Recommends It Best For One Drawback
TurboTax Self-Employed Asks you targeted questions about your specific type of work, surfaces deductions by industry, and makes the self-employment tax calculation transparent rather than buried First-time side hustlers who want to be walked through every step and don’t want to wonder if they missed something It’s the most expensive option on this list — cost may not be justified if your side hustle situation is straightforward
H&R Block Self-Employed Comparable Schedule C guidance to TurboTax, with the added option of dropping into a physical office if something gets complicated mid-filing Side hustlers who want software convenience but like knowing human help is a short drive away The interface isn’t quite as intuitive for first-timers, and the in-person option costs significantly more
FreeTaxUSA Handles Schedule C accurately at a fraction of the cost — federal filing is free, state is typically around $15 Side hustlers who are comfortable reading IRS guidance on their own and just need a functional, affordable tool The interface is more utilitarian, and it won’t prompt you toward deductions the way TurboTax does — you need to know what to look for

What Marcus Likes ✅

  • ✅ The better platforms now import 1099-NEC and 1099-K forms directly from major gig platforms, which cuts down on manual entry errors that can create IRS mismatches
  • ✅ TurboTax and H&R Block both offer estimated quarterly tax calculators built into the self-employed filing flow — this matters because if you owe more than a certain threshold, the IRS may charge an underpayment penalty (consult IRS guidance or a tax professional to understand your specific obligations)
  • ✅ Most major platforms now include a mileage tracker prompt or integration, which is genuinely valuable — the IRS standard mileage rate is a legitimate deduction many side hustlers leave on the table
  • ✅ Audit support is included at some tier level across most of these platforms, which provides at least some peace of mind for first-time Schedule C filers
  • ✅ FreeTaxUSA’s low cost makes it a realistic option for side hustlers with small income amounts where paying $120 for software doesn’t make financial sense

Where These Fall Short ❌

  • ❌ None of these platforms replace a CPA for complex situations — if you’re trying to figure out whether to structure your side hustle as an LLC or S-Corp for tax purposes, that’s a conversation for a licensed tax professional, not a software wizard
  • ❌ The deduction prompts in even the best software are general — they can’t know every industry-specific expense that might legitimately apply to your work, so you still need to do some homework on what the IRS allows for your specific type of business
  • ❌ Quarterly estimated taxes are where many side hustlers get tripped up, and most software only addresses this at filing time — by then, underpayment penalties for the prior year may already be baked in; the CFPB and IRS both recommend side hustlers understand their estimated tax obligations proactively
  • ❌ State tax handling varies considerably — some states have complex rules around self-employment income, and software accuracy at the state level is harder to evaluate than federal; always verify your state’s specific requirements

How I Tested These

I went through the self-employed filing flow on each platform using a test scenario: a W-2 employee with roughly $15,000 in freelance consulting income, a few hundred dollars in deductible home office expenses, and documented mileage. I evaluated how many steps it took to correctly enter Schedule C income, whether the platform proactively prompted for common deductions, how clearly it explained the self-employment tax calculation (which covers Social Security and Medicare contributions that your employer would normally split with you — another thing I learned the hard way), and what the total cost looked like at checkout. I did not accept affiliate positioning as a substitute for functional evaluation.

Marcus’s Verdict

If you’re filing with side hustle income for the first time and you’re not sure what you’re doing, TurboTax Self-Employed is worth the higher cost in that situation specifically — it asks enough targeted questions that it’s hard to miss major deductions, and it makes the self-employment tax calculation legible rather than just spitting out a number. H&R Block Self-Employed is worth serious consideration if you’re the type of person who wants a local office as a backup option. For experienced filers who know their way around Schedule C and want to keep costs down, FreeTaxUSA handles the job accurately and affordably.

Whatever you use, pay attention to your quarterly estimated tax obligations going forward — that’s the piece most new side hustlers miss, and the IRS underpayment penalty situation is avoidable with some planning. If your side income is growing significantly or your situation involves business structure questions, home office deductions you’re uncertain about, or multiple income streams, consider consulting a CPA. Software is a tool, not a substitute for professional judgment in genuinely complicated situations. All rates, fees, and software features are subject to change — verify directly with each provider before filing.
