Works with your own IRS Tax Pro Account account. Fous is an independent product.

## What you can build on Tax Pro Account

### Get active authorizations

Reads the Taxpayers tab of a linked CAF number and, for each taxpayer, the active POA and TIA authorizations recorded on the CAF.

- Takes: Taxpayer name (optional)
- Returns: Taxpayer, individual or business, authorization type, tax matters, tax periods

### Get a client's balance due and payments

Opens one taxpayer from the Taxpayers tab and reads the taxpayer information your authorization covers: balance due, payment activity and, for individuals, audit status.

- Takes: Taxpayer name
- Returns: Taxpayer, balance due, payments with date, amount and tax period, audit status

### Check POA and TIA request status

Reads the history of POA and TIA requests you submitted through Tax Pro Account, with the status each one shows.

- Takes: Submitted since (optional)
- Returns: Taxpayer, request type, tax matters, tax periods, submitted date, status

### Withdraw from an authorization

Opens a taxpayer's authorizations from the Taxpayers tab and withdraws the one you name, which removes it from the CAF at once.

- Takes: Taxpayer name, authorization type, tax matter, tax periods
- Returns: Taxpayer, authorization type, tax matter, tax periods, withdrawn

## Automate Tax Pro Account with a workflow

A [workflow](/product/workflows) runs your methods as one process, with nobody at the screen. A schedule or a call from your own system starts it, the steps run in order, and the result arrives in your inbox or in the systems you already use.

### Weekly client balance due and payment activity check

Starts: Every Monday at 7:00 Eastern time

1. Get the active authorizations to list every taxpayer on the Taxpayers tab.
2. For each taxpayer, get the balance due and payment activity.
3. Keep the clients whose balance due or payments changed since the last run.
4. Email you the list, with balance due and the new payments.

### Approved POA and TIA requests, posted to your practice system

Starts: Every weekday at 8:00 Eastern time

1. Check the status of the POA and TIA requests you submitted.
2. Keep the requests that show approved and did not on the last run.
3. Post each one to your webhook with taxpayer, type, tax matters and tax periods.

### Audit status changes for individual clients

Starts: Every weekday at 9:00 Eastern time

1. Get the active authorizations to list the individual taxpayers on the Taxpayers tab.
2. For each one, get the balance due and audit status.
3. Keep the clients whose audit status changed since the last run.
4. Email you each change with the client's balance due.

You can run a workflow by hand on every plan, Free included. Schedules and webhook triggers come with the paid plans, from $29 a month.

## Once built, one call from your code

Once you have built a [method](/product/methods), it is one POST to /v1/runs from your backend, or a tool an AI agent calls over MCP. This is what “Get active authorizations” would look like.

Example request:

```
curl https://api.fous.com/v1/runs \
  -H "Authorization: Bearer $FOUS_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "method": "sa.www4.irs.gov/get_active_authorizations",
    "input": {}
  }'
```

Example response:

```
{
  "status": "completed",
  "data": {
    "taxpayers": [
      {
        "name": "Acme Holdings Inc",
        "type": "business",
        "authorizations": [
          {
            "type": "POA",
            "tax_matters": "Income Tax",
            "tax_periods": "2023, 2024, 2025"
          }
        ]
      }
    ],
    "count": 1
  }
}
```

An example with invented data, not a ready-made endpoint. The method exists in your organization once you build it, and its name, inputs and fields follow your request.

## Tax Pro Account’s own options

The IRS publishes no API for Tax Pro Account. Its APIs, reached with an approved application and an API client ID, cover TIN Matching, the Transcript Delivery System, IVES and IRIS, not authorizations or client balances. In Tax Pro Account you request, view and withdraw authorizations and view taxpayer information on the site, one taxpayer at a time.

| Option | What it covers | What it takes |
| --- | --- | --- |
| IRS APIs with an API client ID | e-Services TIN Matching, Transcript Delivery System and Secure Object Repository, EFIN validation, IVES and IRIS. None covers Tax Pro Account. | An approved application for the product and an API client ID. |
| Submit Forms 2848 and 8821 online | Uploads a completed Form 2848 (POA) or 8821 (TIA), including for business clients. Processed in the order received, not in real time. | One form at a time, as PDF, JPG or GIF, with attachments in the same file. |
| Tax Pro Account by hand | POA and TIA requests to individuals, active authorizations, withdrawals, taxpayer information, payments and payment plans, one taxpayer at a time. | An IRS sign-in. A linked CAF number to see taxpayers and authorizations; POA requests need authority to practice before the IRS. |

## Signing in to Tax Pro Account

You sign in to Tax Pro Account with ID.me credentials, and an individual CAF number is linked by the person it was assigned to. With Fous you sign in through Tax Pro Account's own sign-in with your own account. The login is sealed with AES-256, never returned by the API or written to logs, and code and AI agents never see it.

## Worth knowing

- **Link your CAF number first**: Taxpayers and active authorizations appear only after you link your CAF number. The IRS mails a PIN to the CAF address, which takes 1 to 2 weeks, and a linked CAF number cannot be unlinked.
- **Requests go to individuals only**: POA and TIA requests in Tax Pro Account reach individual taxpayers, who approve them in their Online Account within 120 days. Business clients still need Form 2848 or 8821.
- **The site has hours of service**: Tax Pro Account is available Monday 6 a.m. to Saturday 9 p.m. Eastern time, and Sunday 10 a.m. to midnight Eastern time. Schedule workflows inside those hours.
- **You see only what you are authorized for**: Taxpayer information is limited to the forms and tax periods approved under your authorization. A new authorization revokes prior ones for the same tax matters, periods and types.

## Frequently asked questions

### Does IRS Tax Pro Account have an API?

No. The IRS publishes no API for Tax Pro Account. Its APIs, reached with an approved application and an API client ID, cover TIN Matching, the Transcript Delivery System, IVES and IRIS. Authorizations, balances and payment activity are handled on the site, one taxpayer at a time.

### Can I see all my clients in Tax Pro Account?

Yes, once you link your CAF number. You then see all the active POA and TIA authorizations on your CAF, from individuals and businesses. You open a client from the Taxpayers tab to see their authorizations and taxpayer information.

### Why does my POA or TIA request show no status?

No status is shown when the taxpayer rejected the request or when they approved it and processing failed. An approved request should appear right after the taxpayer approves it. Until processing finishes, the IRS says to check the status with the taxpayer.

### Can I request a POA for a business client in Tax Pro Account?

No. Requests in Tax Pro Account go to individual taxpayers. For a business, you submit Form 2848 or 8821, for example by uploading it online. You can view business clients' balance due and payment activity, and make certain payments for them, in Tax Pro Account.

### Is Fous affiliated with the Internal Revenue Service?

No. Fous is an independent product. You use it with your own Tax Pro Account sign-in, and a method reads and does only what that account can.

Fous is an independent product: it is not affiliated with, endorsed by or sponsored by the operator of IRS Tax Pro Account (Internal Revenue Service). The name is used only to say which system this page is about. Something here wrong or out of date? Write to legal@fous.com.
