Built for the 2027 filing season

Get returns signed, paid and filed without chasing clients.

TaxFlow is the client portal and workflow for US tax firms. Clients upload documents, sign and pay in one place, and your team sees exactly what's blocking every return. It works for clients in the US and overseas.

Why firms switch

Less admin. Faster returns. Happier clients.

Most of tax season is spent chasing, not preparing. TaxFlow takes the chasing off your team's plate.

Stop chasing

Clients know what to send

Personal checklists and automatic reminders by email or WhatsApp mean documents arrive without your team asking twice.

Get paid on time

No payment, no filing

Clients pay online before release, and you approve any exceptions. No more invoices chased after the deadline.

Never miss a step

Every return, one status

Review, signatures, payment and e-file all have to be green before a return goes out, and everyone can see where each one stands.

Without TaxFlow

  • Documents spread across email, WhatsApp and Dropbox
  • Spreadsheets to track who's missing what
  • Chasing signatures and unpaid invoices by hand
  • "Where's my return?" calls all season

With TaxFlow

  • One secure portal for every document
  • A live status for every engagement
  • Online e-signature and payment
  • Clients see their progress themselves

Features

Everything between "new client" and "return accepted"

Stop chasing documents over email and WhatsApp. TaxFlow tracks every engagement and won't let a return go out until it's ready.

🧾

Guided client intake

Questionnaires adapt to each household (filing status, foreign income, accounts abroad) and show clients exactly what's still missing.

📂

Secure document collection

Clients upload W-2s, 1099s and foreign statements to an encrypted vault. Versioning and audit logging are built in.

🤖

Data extraction

Key fields are pulled from uploaded forms for your preparers to confirm, so they spend less time on manual entry.

🔗

Preparation software sync

Engagements sync with your preparation software, with automatic retries and reconciliation when a request fails. CCH Axcess connector in beta.

✍️

Review & e-signature

Reviewer sign-off, then 8879 signatures from every required signer. Changing the return invalidates its approvals automatically.

💳

Invoicing & payments

Send invoices and take card payments online. Admins can authorise exceptions, and every one is logged.

🚦

E-file release gates

A return can't be released without review approval, all signatures and payment (or an authorised exception).

📣

Email & WhatsApp updates

Automatic reminders and status updates through each client's preferred channel. WhatsApp only with consent.

🌍

Built for clients abroad

Firm timezone throughout, plus a portal that works for US citizens living overseas and the firms that serve them.

How it works

One clear path for every engagement

Clients and staff see the same status, so nobody has to ask where things stand.

Invite & onboard

Create the household, invite the signers, and send the season's engagement letter.

Collect intake & documents

Clients fill in the questionnaire and upload documents while TaxFlow tracks what's outstanding.

Prepare

Extracted data flows to preparation. Information requests go back to the client in one click.

Review

Reviewers approve or reject with reasons, and every return version is kept.

Sign & pay

Clients e-sign and pay online. Release unlocks only once all the gates are green.

File & track

Release for e-file and follow the acknowledgement through to accepted, or handle a rejection.

Security

Designed for taxpayer data from day one

Tax data is about as sensitive as data gets. TaxFlow encrypts it, restricts access to it and logs every touch.

  • Envelope encryption for identifiers and documents; TINs are never logged
  • Mandatory TOTP multi-factor authentication for every staff user
  • Role-based access: client, preparer, reviewer, firm admin
  • Strict tenant isolation: each firm's data is separated at the database layer
  • Tamper-evident, hash-chained audit log of every access and decision
  • Idempotent webhooks and crash-safe background jobs

FAQ

Questions, answered

Who is TaxFlow for?

US tax firms of any size, especially firms with clients overseas who need a portal that works across timezones.

Do my clients need to install anything?

No. Clients use TaxFlow in any modern browser on desktop or mobile.

Does it replace my preparation software?

No. TaxFlow manages the client relationship and workflow around preparation and syncs with your preparation software. The CCH Axcess connector is currently in beta.

How is my firm's data kept separate?

Every record belongs to exactly one firm, and access is enforced server-side on every request. Staff only see their own firm's clients.

What happens when the trial ends?

Pick a plan to keep going. If you don't, your workspace is paused rather than deleted, so you can export or come back later.
