LLC Tax Preparation Software: The Real Alternative to Hiring a CPA

LLC tax preparation software is a legitimate alternative to a CPA if your return is straightforward — a single-member LLC filing Schedule C, or a multi-member LLC filing Form 1065 with a handful of partners, clean books, and no multi-state complexity. Tools like TaxAct Business or H&R Block Premium & Business let you prepare that return yourself for roughly $100 to $250, compared with the $800 to $2,500+ a CPA typically bills for the same form. What you lose is audit representation and someone proactively flagging a strategy change — and none of this software fixes messy books for you.

What a CPA actually charges an LLC per year

CPA fees for an LLC aren't a flat number — they scale with the form you file and how clean your books are when you hand them over. The most recent form-by-form data from the National Society of Accountants puts the national average at $733 for a Form 1065 partnership return and $903 for a Form 1120-S, the form an LLC files once it elects S-corp tax treatment. Those averages are a floor, not a ceiling: practice-management guides published in 2026 put the real-world range for a small multi-member LLC at $800-$1,500 for a simple two- or three-partner return, climbing to $1,500-$5,000+ once there are multiple K-1s, partner basis calculations, or more than one state involved.

Add bookkeeping cleanup — the thing most CPAs bill separately before they'll even start the return — and it's easy to see how a single-member LLC lands near $800 while a three-partner LLC with messy books and two state filings lands near $2,500. That spread is exactly why 'software or CPA' doesn't have one answer; it depends which end of that range you're at.

What LLC tax preparation software does instead

Self-filing tools don't replace a CPA's judgment — they replace the mechanical part of the job: taking the numbers you already have and putting them on the right IRS form, in the right boxes, with the K-1s generated automatically.

Form 1065 for multi-member LLCs

If your LLC has two or more members and hasn't elected corporate taxation, you file Form 1065, U.S. Return of Partnership Income. Software built for this form takes your income and expense totals, allocates profit and loss by each member's ownership percentage, and generates a Schedule K-1 for every partner. TaxAct Business, for example, prices its online Form 1065 package at $159.99 plus $69.99 per state — well under the $733 national average a CPA charges for the same form before any state add-ons.

Form 1120-S for S-corp elections

An LLC that filed Form 2553 to be taxed as an S-corporation files Form 1120-S, U.S. Income Tax Return for an S Corporation instead of Form 1065. This is the form where software is least forgiving: it needs accurate officer payroll data, shareholder basis, and distribution records already reconciled in your books before it can produce a correct return. H&R Block Premium & Business, which supports 1120-S, starts at $99 for the download plus state fees.

Schedule C for single-member LLCs

A single-member LLC that hasn't elected corporate taxation is a disregarded entity for federal tax purposes — its income and expenses go on Schedule C, filed with the owner's Form 1040. Nearly every consumer tax program (TurboTax, H&R Block, TaxAct) already handles this in its standard business tier, which is why single-member LLCs are usually the cheapest and safest entity type to self-file.

What you gain and what you give up going DIY

Lower cost and faster filing

• A simple Form 1065 filed through TaxAct Business runs about $160-$230 total versus $733-$1,500 for a CPA — a realistic savings of $500-$1,000 for a clean two- or three-partner LLC.
• No waiting in a CPA's queue during the March-April crunch; you file whenever your books are ready.
• No separate charge for follow-up questions — most software bundles unlimited use of the forms you've already paid for.

No audit representation, no strategic tax planning

The trade-off is real, not theoretical. If the IRS sends a notice or opens an examination, tax software doesn't show up for you — a CPA who prepared and signed the return typically can, and some firms include a limited amount of that representation in their fee. Software also won't tell you, in July, that reclassifying a partner's guaranteed payment or timing an equipment purchase differently would lower next April's bill; a CPA relationship is where that kind of planning happens, and it's the part self-filers give up first.

When self-filing stops making sense for an LLC

Software is only as good as its inputs. It's the wrong tool — not just a riskier one — in a few specific situations:

• Your LLC does business in more than one or two states and you're not sure where you have nexus.
• Partners have special allocations, mid-year ownership changes, or contributed property instead of cash.
• You're converting, or considering converting, from an LLC to an S-corp election this year.
• You've already received an IRS notice, or expect one, tied to a prior return.
• Your books aren't reconciled — bank feeds are months behind, or you're unsure what's deductible. No tax software fixes bad bookkeeping; it just formats it faster.

That last point is also the most common reason self-filed LLC returns come back inaccurate: the software did exactly what it was told, with numbers that weren't right in the first place.

A hybrid option: software that also keeps your books all year

Here's the gap most pure tax-prep tools don't cover: TaxAct and H&R Block are built for the six weeks around your filing deadline. They assume your books are already closed and correct when you open the program — which is exactly where many LLC owners struggle, since a lot of them also pay a separate bookkeeper $200-$800 a month on top of their CPA's annual fee just to keep the numbers in shape.

Kangaroo ERP's tax module is built to close that gap: it computes Schedule C + Schedule SE for single-member LLCs and Form 1065 with a K-1 per partner for multi-member LLCs directly from the books the platform's AI keeps reconciled all year, instead of from a tax-season questionnaire. It also tracks quarterly estimated payments using both IRS safe-harbor methods and flags when the prior-year method isn't available because it's your first filing year.

Worth saying plainly, because the honest comparison matters more than the pitch: at $3,990-$4,900 a year, Kangaroo ERP's Solo and Company plans cost more than a pure tax-filing tool like TaxAct or H&R Block, and for an LLC with clean books and a simple return, standalone software is still the cheapest path. Where an all-in-one platform tends to make financial sense is if you're currently paying for a bookkeeper and a CPA separately — add a $200-$800/month bookkeeping fee to an $800-$2,500 CPA bill and the two together often land close to, or above, what a bundled plan costs, with one system instead of two and nothing to reconcile between them.

FAQ

Can I prepare my own LLC tax return?

Yes, for single-member LLCs (Schedule C) and most straightforward multi-member LLCs (Form 1065), provided your books are reconciled and you don't have multi-state, basis, or audit complications.

Is tax software as reliable as a CPA for an LLC?

It's reliable at the mechanical part — correctly placing your numbers on the right form and generating K-1s. It isn't a substitute for audit representation or proactive tax planning, and it can't catch errors already baked into your bookkeeping.

What's the cheapest way to file LLC taxes?

For a single-member LLC under the IRS income threshold, the IRS Free File program can prepare Schedule C with your Form 1040 at no cost. For a multi-member LLC there's no free federal e-file option for Form 1065 — the lowest-cost route is typically TaxAct Business's online 1065 package at $159.99 plus $69.99 per state.

When should an LLC hire a CPA instead of using software?

Once you have multi-state nexus, special partner allocations, an entity conversion, an IRS notice, or books that aren't reconciled — any one of those pushes the cost of a mistake well above what you'd save on software fees.
