Taxfyle vs TurboTax for complex returns (2027): when DIY and Expert Full Service aren't enough

TurboTax is the best-known name in tax software, and for many households it does the job well. But once a return picks up Schedule K-1s, crypto sales, income in more than one state, or a business, the question changes. You're no longer asking "Which software should I use?" You're asking "Who should actually prepare this return?"

This guide compares TurboTax's public offers with Taxfyle, an online marketplace where licensed CPAs and EAs on the Taxfyle platform prepare and file returns. Every TurboTax price and coverage detail below comes from Intuit's own public pages, checked October 20, 2026. Intuit may change prices for the 2027 filing season, so check its site before you buy.

What "complex" usually means in this comparison

There's no official IRS definition of a complex return. In practice, these are the situations where people most often start comparing DIY software with a professional:

• Schedule K-1 income. Partners, LLC members, and S-Corp shareholders receive K-1s that feed into their personal return. Basis, passive-activity rules, and late or corrected K-1s all add work.
• Crypto and other digital assets. Sales and exchanges have to be reported, and brokers now issue Form 1099-DA for digital asset dispositions.
• Multi-state income. Moving mid-year, working remotely for an out-of-state employer, or owning rental property in another state can mean several state returns.
• Business income. Freelancers and sole proprietors report on Schedule C, often with depreciation, home-office, and vehicle questions.
• Business entity returns. S-Corps (Form 1120-S), partnerships and multi-member LLCs (Form 1065), and C-Corps (Form 1120) file their own returns, separate from the owners' 1040s.

You can have one of these or all of them. The more of them stack up, the more a return depends on judgment calls rather than data entry.

What TurboTax DIY covers well (and where people outgrow it)

Per Intuit's TurboTax Online page (as of October 20, 2026), TurboTax Do It Yourself is listed at $0 to $139 for federal filing, depending on the edition. Intuit says the Free Edition is limited to simple Form 1040 returns and that roughly 37% of taxpayers qualify. Paid DIY editions cover a wide range of situations. Intuit lists W-2 income, investments including stocks and crypto, rental property income, and guidance for freelancers and the self-employed.

TurboTax DIY also offers an Expert Assist tier, where you prepare the return yourself with on-demand help and a final review from an Intuit tax expert.

So the software itself handles a lot. People usually outgrow DIY for a different reason: in DIY, you're still the one making the decisions. The software asks the questions, but you decide how to treat a K-1 with a basis problem, how to split income between states, or whether a business expense qualifies. If you're not sure your answers are right, guided software can't fully solve that.

What TurboTax Expert Full Service publicly includes and excludes

Expert Full Service is TurboTax's "an expert does it for you" option. Intuit offers it in two forms: one for personal returns and a separate one for business returns.

Personal Expert Full Service: priced form by form

Per Intuit's Full Service forms price list (updated April 1, 2026, checked October 20, 2026), personal Expert Full Service starts with a federal base price and adds charges for each form:

• Federal base: $89 early season, $129 late season and after April 1. The base includes one W-2 and one Form 1040.
• State returns: $49 early season and $69 late season, per state.
• Example form charges: $40 for each Schedule K-1 from a partnership (Form 1065) or S-Corp (Form 1120-S), $40 for each Form 1099-B or 1099-DA, and $80 to $200 for Schedule C, depending on reported business expenses.

Intuit says your expert gives you a price estimate before starting and confirms the final price before filing. The expert signs the return as the preparer.

Business entity returns are a separate TurboTax product

The personal price list covers Form 1040 and its schedules, not the entity's own return. Per Intuit's small business page (as of October 20, 2026), S-Corp, partnership, and multi-member LLC returns go through TurboTax Expert Full Service Business. Intuit lists that service at $1,549 federal for S-Corps filing Form 1120-S and for partnerships filing Form 1065, with state returns extra.

Intuit's promotional Expert Full Service offer for the 2026 season also excluded S-Corp, partnership, and multi-member LLC returns, per the offer terms on Intuit's TurboTax Online page.

What Intuit says its business products don't support

According to the disclosures on Intuit's TurboTax Online and small business pages (as of October 20, 2026), TurboTax Expert Assist Business and Expert Full Service Business currently don't support:

• C-Corps (Form 1120) and entities that elect to be taxed as C-Corps
• Trusts and estates (Form 1041)
• Tax-exempt entities and nonprofits
• Returns that require more than five state filings

Intuit also says its Expert 365 Business subscription isn't available to C-Corps, S-Corps, or partnerships.

None of this means TurboTax can't handle a complex personal return. It can handle many of them. The gaps are specific: certain entity types, high state counts, and a pricing model where each added form adds to the bill.

What Taxfyle does instead

Taxfyle is an online tax marketplace. Independent, licensed CPAs and EAs on the Taxfyle platform prepare and file returns. You don't buy software and do the work yourself.

Here's how it works:

1. Answer a few questions about your tax situation. Your quote appears at checkout, before you pay anything.
2. Upload your documents through Taxfyle's secure portal.
3. A licensed CPA or EA on the Taxfyle platform prepares your return and follows up on anything that's missing.
4. You review the return before it's filed.

Taxfyle is built for complex individual returns, including K-1s, crypto, multi-state income, and self-employment income. Taxfyle maintains SOC 2 Type II, ISO 27001, and ISO 27017 certifications.

Side-by-side: TurboTax vs Taxfyle for complex returns

When staying in TurboTax is fine, and when a pro on Taxfyle is the better next step

Staying with TurboTax probably makes sense if:

• Your return is mostly W-2 income, standard investment forms, and one state.
• You're comfortable answering the software's questions and confident in your answers.
• You have a sole proprietorship with simple bookkeeping and want to keep doing it yourself.
• You like having a large DIY product with built-in guarantees and are happy with how its prices add up for your forms.

A licensed CPA or EA on Taxfyle may be the better next step if:

• You receive several K-1s, or a K-1 that arrives late or gets corrected.
• You sold crypto across multiple wallets or exchanges and aren't sure your cost basis is right.
• You owe returns in several states, or more than five.
• You're self-employed and want a professional to handle Schedule C, depreciation, and home-office questions on your personal return.
• You'd like a quote based on your situation before you commit, rather than a total that grows form by form.
• You simply want a licensed professional to make the judgment calls.

Frequently asked questions

Can TurboTax file my S-Corp return?

Yes, through its business products. Per Intuit's small business page (as of October 20, 2026), TurboTax Expert Full Service Business covers S-Corps filing Form 1120-S and partnerships filing Form 1065 and lists both at $1,549 federal, with state returns extra. Intuit says its online business products don't currently support C-Corps, trusts and estates, nonprofits, or returns that need more than five state filings.

Do I need a CPA for a Schedule K-1?

Not legally. Anyone can enter a K-1 into tax software. But K-1s often involve basis tracking, passive-loss limits, and state-source income, and many K-1 recipients prefer to have a licensed CPA or EA review those items. If you have several K-1s, or one arrives late or gets corrected, professional preparation is worth considering.

Can TurboTax handle crypto and multi-state returns?

Intuit says its DIY products cover crypto and other investments. Its personal Expert Full Service price list charges per Form 1099-B or 1099-DA and per state return. The question is less whether the software can report these items and more whether you're confident in the cost basis and state allocation behind them.

Who prepares my return on Taxfyle?

An independent, licensed CPA or EA on the Taxfyle platform. Taxfyle is a marketplace that matches you with a professional for your return.

How much does Taxfyle cost?

You answer a few questions about your situation, and your quote appears at checkout before you pay anything. Pricing depends on the return.
