Here is the product working, right now, on this page

Produced a moment ago by the same filing-calendar engine that runs inside Kangaroo, for three example businesses. Dates that land on a weekend or a federal holiday are already moved to the next business day.

Example profiles, not customers, and no real taxpayer data. Federal deadlines only — your state adds its own, and those load with your state when you create the business.

If any of this sounds like your year, you're in the right place

You sell into several states and you're not sure where you owe sales tax

Kangaroo tracks your sales by state against each state's own threshold and tells you where you stand — with time to register before it matters.

You own a US LLC and you're not a US person

Kangaroo has the whole §6038A package as a module: an ETBUS questionnaire, a related-party register, and the pro forma 1120 and 5472 built from your own ledger — with a Schedule K-1 per member if there is more than one.

You run an S corp and want the salary/distribution split done properly

The product runs the payroll, tracks the compensation against the profit, and gives you the figures to discuss with your CPA in one screen.

Your quarterly estimates are a rough guess every three months

Kangaroo computes both routes from your live numbers, tells you which is lower, and shows the exact amount and date for each of the four instalments.

Payroll takes half a day and you still double-check it by hand

One click produces the run, and every paycheck opens up into the full IRS worksheet so you can see exactly where each number came from.

You bought equipment and don't know how to write it off

Enter the asset and Kangaroo shows the full year-by-year schedule, with Section 179 and bonus applied, before you save it.

The mechanism

The Form-Line Ledger

You tell us how your business is organized and how it elected to be taxed. From that moment every account in your ledger carries the form line it belongs on — so the return is an aggregation, not an interview.

  1. 1

    Your chart of accounts appears

    Seeded for your exact tax classification, every account already mapped to its form line.

  2. 2

    Your filing calendar generates

    Real dates, moved for weekends and federal holidays — the engine you just saw.

  3. 3

    Your state rules load

    Withholding, unemployment, disability and paid leave, sales tax and nexus thresholds.

  4. 4

    You start working

    Invoice, record expenses, run payroll. The returns add up from what's already there.

Who this is for

Sole proprietors and single-member LLCs

You file a Schedule C and pay self-employment tax, and you want the quarterly estimates to stop being guesswork.

Foreign owners of US LLCs

You owe no US income tax and you still have a $25,000-penalty filing to make every year. You want it built from your books instead of reconstructed by someone billing hourly.

S corporations

You need payroll running properly and the compensation-to-distribution picture visible all year, not reconstructed in March.

Partnerships and multi-member LLCs

You need Form 1065 and a Schedule K-1 per partner, on time, because every partner's own return waits on it.

C corporations

You want the books clean, the 1120 computed from them, and the payroll for owner-employees handled in the same system.

Spanish-speaking owners

You run your business in Spanish but file in English. The product does both, and never invents Spanish names for US forms.

Who it isn't for — and we'd rather say so now

  • You want somebody to transmit the return to the IRS for you. We prepare it; we do not file it.
  • You want tax advice about your particular situation. That is a CPA or an enrolled agent, and we will happily be the system they work from.
  • You have no US entity yet and no plans to form one. Come back when you do — there is nothing here for you today.
  • You are hunting for the cheapest possible tool. Setting up is free; running your year on Kangaroo starts at $490 a month, and we would rather say that now than on the call.

How the demo works

It's a working session, not a slide deck. Thirty minutes, by video, with your own situation on screen.

  1. 1

    You tell us your setup

    Classification, state, employees or contractors. Two minutes and we know what you're dealing with.

  2. 2

    We generate your calendar live

    Your actual filing obligations and due dates, produced from what you just told us — the same engine you already saw running on this page, now with your own answers in it.

  3. 3

    We run a real calculation

    A payroll run, a sales tax breakdown or a return, with the worksheet open, on numbers that look like yours. You see exactly how each figure is produced.

  4. 4

    You ask whatever you want

    Bring the question you've been meaning to ask someone. Half the value of the call is usually here.

No slide deck, no follow-up sequence, no pressure. If it isn't a fit, we'll tell you on the call — and if what you need is a CPA rather than software, we'll tell you that too.

Questions people ask before booking

Do you file my returns with the IRS?

No, and it matters enough that it is the first question here. We are not an Authorized IRS e-file Provider. Kangaroo prepares the return from your ledger, complete and reconciled, and you or your CPA file it under your own signature. For the foreign-owned LLC package, nobody e-files it at all: the pro forma 1120 with Form 5472 goes to Ogden, Utah, by fax or by mail.

I already have a CPA. Does this replace them?

No — it makes them faster and cheaper. What your CPA charges most for is untangling a year of scattered records. Clean books already mapped to form lines remove that work entirely, and they get to spend the time on the planning that's actually worth paying for.

I'm an LLC. Which setup is that?

LLC is how you're organized under state law, not how you're taxed. An LLC can be taxed as a sole proprietorship, a partnership, an S corporation or a C corporation — and if its owner is not a US person, as a foreign-owned disregarded entity with its own reporting package. On the demo we'll pin down which one you actually are. For a lot of people that turns out to be the most useful part of the call.

What does it cost?

Kangaroo Company is $490/month for one entity with up to 10 employees on payroll, with no setup fee and no sales call. Firms start at $5,900 of onboarding plus $1,190/month for a book of up to 75 clients, because we migrate and reconcile the whole book for you. Paying for a full year bills ten months instead of twelve. Every form your entity requires is included — no per-filing fees, no April surcharge. We'll confirm which plan fits on the call.

My books are behind. Is it too early?

It's the best time. Most people who book are behind — that's usually why they book. Bring what you have; messy real data makes the demo far more useful than tidy hypothetical data.

Can I use it in Spanish?

Yes. The entire product is in English and Spanish under the same login, and you can switch at any time. Form names stay in English on purpose so what you see matches what arrives in the mail.

How is your business taxed?

LLC is how you're organized, not how you're taxed. Not sure? That's common — pick it and we'll work it out on the call.
