Books that close themselves
Settlements and fees become double-entry books: FBA, referral, storage, PPC, refunds, reimbursements. COGS with FIFO per SKU, computed from your order totals and inventory counts.
Know you are compliant. Every day.
Taxller turns your Amazon settlements into clean double-entry books, tracks every filing deadline, and prepares the tax forms — a green dashboard means our checks found nothing outstanding.
From $49/mo · Free plan · No credit card · 500 welcome tokens
Built by Amazon sellers, for Amazon sellers
We created Taxller to take the hardest part of a seller’s work — books, deadlines and tax forms — off your plate. We run a foreign-owned US LLC selling on Amazon ourselves: every form we ask you to trust, we file for our own company first.
Your 1099-K says $500,000. Your bank says $312,400.
Fees, refunds, reserves and facilitator tax hide 30–45% of your gross. Taxller explains the gap line by line — before the IRS asks.

Three jobs, done every day
Compliance cockpit
Your entity profile becomes an obligations map: every federal and state deadline tracked with green, amber and red status — and the next action.
Forms, filled
Form 5472 + pro-forma 1120 for foreign-owned LLCs, Schedule C data packs for residents — generated from your books, with a guided filing wizard.
Foreign owner of a US LLC? Built for you.
The penalty for a missed Form 5472 starts at $25,000 (IRC §6038A(d)) — and the IRS assesses it systematically on late filings. We run a foreign-owned LLC selling on Amazon ourselves; Taxller prepares exactly the package the IRS expects.
How it works
- 1
Connect Amazon
Secure OAuth: you grant access on Amazon, not here. Three clicks, no buyer data requested. Taxller reads only what bookkeeping needs: financial reports, order and inventory totals, FBA placements across fulfillment centers, and account-level insights.
- 2
Answer the questionnaire
Entity type, owner residency, state — your personal compliance map and calendar appear before the first sync finishes.
- 3
Watch it stay green
Books close daily, deadlines are tracked, forms are ready when the season comes. Amber means: here is the next action.
You stay in control
Every draft waits for you
Nothing is filed or sent on your behalf. Every form is a watermarked draft until you approve it — then the wizard walks you through filing.
An archive that answers
Books, forms and their source numbers are kept year after year. When the IRS asks in 2029 about 2026, the answer is one click away — not a shoebox.
Rules tracked by us, not your bookmarks
IRS forms, thresholds and state rules change. Taxller keeps them current for you, and every tax page shows the filing year it is written for.
Your data works only for you
It is used to build your books and forms — never sold, never shared. Assistant questions are processed by Amazon Bedrock, in US regions, inside an AWS account dedicated to Taxller. Your data is not sent to third parties or used to train models. When we search official sources, only closed-vocabulary topic parameters leave Taxller — never the text of your question, names, or identifying organization data.
We will also tell you what you do NOT need
In marketplace-facilitator states Amazon already collects and remits 100% of marketplace sales tax. Most Amazon-only sellers do not need a sales-tax subscription — we show the statute and say so plainly.
Also in the box
Etsy and Wayfair too
Multi-channel sellers get one set of books. Amazon, Etsy and Wayfair connectors are being built; today you upload the reports and Taxller does the rest.
Your accountant will thank you
One clean CPA-ready pack to review and file from — instead of hours of spreadsheet archaeology.
Ask your books a question
The built-in assistant answers from your numbers and shows its sources — and says “this needs a human” rather than guessing.
In your language
English, Español, Русский, 中文 — US taxes explained in the language you think in.
Bring a friend
Referrals earn 500 tokens for you and 500 for them.
Simple pricing
PRO, MAX and ULTRA plans at $49 / $99 / $199 per month (annual −20%) cover the compliance cockpit, deadline tracking, Nexus and your document archive, plus a monthly AI budget included in every plan; automated bookkeeping features join each plan as they ship.
Many times cheaper than running your books through an accountant — and your CPA still gets cleaner numbers than ever.
One-off work runs on tokens: 500 free at signup, 20 tokens per assistant question (+10 per attached file); only subscribers can top up tokens, and the annual 5472 + 1120 package will be offered for 14,900 tokens.
Subscriptions renew automatically until cancelled — cancel anytime in your billing portal.
Get startedFrequently asked questions
Do I have to be a US resident?
No. Taxller was built first for non-resident owners of US LLCs (Form 5472 + pro-forma 1120), and fully supports US residents filing Schedule C. The onboarding questionnaire adapts everything to your case.
I already have an accountant. Why Taxller?
Keep them — Taxller does the daily work: books, reconciliation, draft forms. Your accountant reviews a clean pack instead of reconstructing a year of settlements, so their hours (and your bill) shrink.
Will Taxller file forms without asking me?
Never. You see every form as a watermarked draft, approve it yourself, and the filing wizard guides you through the exact steps the IRS expects.
How will I know a deadline is coming?
Your personal calendar reminds you 60, 30, 7 and 1 day ahead — each reminder explains what the obligation is and what exactly to do next.
What happens to my data and documents?
They stay in your account and build your archive: books, forms and source numbers, year after year, exportable any time. We never sell or share your data.
Tax rules change constantly. Who keeps up?
We do — forms, thresholds and state rules are updated inside Taxller, and every tax page is marked with the filing year it is current for.
Stop wondering. Start knowing.
