Automate MyTax 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.

• Catch PCB files marked Gagal before the 15th

  Build this

  Starts

  Every month on the 10th at 9:00, Malaysia time

  Step 1

  For each employer you name, list the uploaded e-Data PCB files for last month.

  Step 2

  Keep the employers whose file is marked Gagal, or who have no file for that month.

  Step 3

  Email you the list with each employer, file name and the errors from Laporan Ujian Data.

• Send new e-Filing acknowledgement receipts to your records

  Build this

  Starts

  Every Monday at 8:00, Malaysia time

  Step 1

  For each employer or company, get the e-Filing acknowledgement receipts for the current year of assessment.

  Step 2

  Keep the receipts that were not there on the last run.

  Step 3

  Post employer, form, year of assessment and submitted date to your 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 “List uploaded e-Data PCB files” would look like.

curl https://api.fous.com/v1/runs \
  -H "Authorization: Bearer $FOUS_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "method": "mytax.hasil.gov.my/list_e_data_pcb_files",
    "input": {
      "employer": "Acme Sdn Bhd",
      "month": "2026-10"
    }
  }'

{
  "status": "completed",
  "data": {
    "employer": "Acme Sdn Bhd",
    "month": "2026-10",
    "files": [

        "file_type": "txt",
        "uploaded_at": "2026-11-07",
        "result": "Gagal",

            "field": "Income tax number",
            "message": "Invalid format"
          }
        ]
      }
    ],
    "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.

MyTax’s own options

HASiL offers no API for monthly tax deductions or return forms. Employers submit MTD (PCB) only through e-PCB, e-Data PCB or e-CP39 on MyTax, free of charge, and e-Data PCB takes the payroll data as a .txt or .zip file. HASiL's MyInvois API covers e-invoices only.

Signing in to MyTax

MyTax asks you to pick a Jenis Pengenalan (MyKad/MyPR/MyKAS, or passport or other document), enter the number, then your Kata Laluan (password). After signing in you choose a role in Pilihan Peranan, such as Majikan (employer). With Fous you sign in once through MyTax's own sign-in with your own account: the login is sealed with AES-256, and an expired session is signed back in.

Worth knowing

PCB is due by the 15th

MTD must reach HASiL on or before the 15th day of the following month. Employers may use only e-PCB, e-Data PCB or e-CP39 on MyTax to submit the MTD statement or data.

Over 2 MB, upload a .zip

e-Data PCB takes a textfile format (.txt) or a zip file (.zip). Data of 2 MB and above must be converted from .txt to .zip before you upload it.

A failed file is deleted and uploaded again

A file whose Keputusan is Gagal shows its errors in Laporan Ujian Data. You delete it, correct the data and upload again before Pengesahan and Bayaran.

Form E needs C.P.8D by 31 March

Employers file Form E through e-Filing on or before 31 March of the following year, and it counts as complete only with C.P.8D, unless the data went in through e-Data Praisi.
