Automate myconneCT with a workflow

A workflow 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.

  • Unfiled periods and balances due, every account

    Build this
    Starts
    Every weekday at 7:00, Eastern Time
    Step 1
    For each tax account you name, get the return periods and balances.
    Step 2
    Keep the periods that are not Return Filed or that show a balance.
    Step 3
    Email you the list, one section per account, with tax, penalty and interest due.

  • New DRS letters, posted to your team

    Build this
    Starts
    Every weekday at 9:00, Eastern Time
    Step 1
    List the DRS letters from the last 30 days.
    Step 2
    Keep the letters that were not there on the last run.
    Step 3
    Post each one, with its date, title and tax account, to your team's system by webhook.

  • Processed returns and payments, handed to accounting

    Build this
    Starts
    Every Monday at 8:00, Eastern Time
    Step 1
    Get the processed submissions from the last 7 days.
    Step 2
    Keep the ones that were not there on the last run.
    Step 3
    Post type, tax account, period, amount and confirmation number to your accounting system's webhook.

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, it is one POST to /v1/runs from your backend, or a tool an AI agent calls over MCP. This is what “Get return periods and balances” 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": "drs.ct.gov/get_return_periods",
    "input": {
      "tax_account": "Sales & Use",
      "periods_since": "2026-06-30"
    }
  }'
Example response
{
  "status": "completed",
  "data": {
    "tax_account": "Sales & Use",
    "periods": [
      {
        "period_ending": "2026-09-30",
        "status": "Submitted",
        "tax_due": 4215.6,
        "penalty": 0,
        "interest": 0,
        "payment_date": "2026-10-28",
        "payment_amount": 4215.6,
        "balance": 0
      }
    ],
    "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.

MyconneCT’s own options

DRS documents no API for myconneCT. Its File Import, used by third party bulk filers, takes returns as a pre-defined CSV and W-2 or 1099 information returns as EFW2 or 1220 text files. Periods, balances, letters and submissions are read on screen.

File Import, pre-defined CSVUploads sales and use, withholding, estimate and extension filings: one row per return, checked in real time, with a confirmation number when accepted.The DRS file layout for each tax type, from the Bulk Filers page. No limit on upload attempts.

Signing in to myconneCT

myconneCT signs you in with a username and password, or with a passkey. Two-step verification is optional and sends a code by text message, email or an authentication app, and an idle session logs out after 15 minutes. With Fous you sign in once through myconneCT's own sign-in with your own account: the login is sealed with AES-256, an emailed code is handled, and an expired session is signed back in.

Worth knowing

Submitted is not yet filed
A return shows Submitted until DRS processes it, then Return Filed. Search Submissions splits Pending from Processed, so a check for open items should read both.
Only myconneCT payments show
Payment history lists only payments made through myconneCT. Returns filed in the TSC are viewed in the TSC.
A pending file can be replaced only that day
A corrected W-2 or 1099 file can be deleted and resubmitted only while the original is still pending on the day it was sent. After that you amend the return in myconneCT.
Payments count until 11:59 PM Eastern
A payment is timely when it is made by 11:59 PM Eastern Time on the due date, and a return counts as filed on the day you submit it. Returns can be amended up to 42 months back.

Frequently asked questions

No. DRS documents File Import instead: you upload returns as a pre-defined CSV, and W-2 and 1099 information returns as EFW2 or 1220 text files. Periods, balances, letters and submissions are read on screen.

In View/File Returns and View Period Detail for the tax type. Open the period with a balance due to see the tax, penalty and interest, and any payments applied with their dates. The Action Center also lists accounts with an outstanding balance.

Under View Letters in the Correspondence group of the More… menu. If you set Mail Delivery to Email under Settings, DRS sends a notice to your profile's email address when new correspondence is ready, while permits are still mailed.

Yes. Add Access to Another Business gives immediate access without the client confirming, and bulk uploads need no access to each client. Third parties cannot close a client's accounts or request a payment plan.

No. Fous is an independent product. You use it with your own myconneCT account, and a method reads and does only what that account can.
