GST detective: decode 5 real bills

You pay GST every day and probably can’t read it. Collect 5 real bills across purchase types, decode the tax on each with AI as your jargon-translator, verify every rate against official schedules, and find one oddity worth explaining.

The work brief

  1. 01Collect 5 real bills (yours or family’s) across different categories. Photograph them, redacting anything private.
  2. 02Decode each with AI’s help: taxable value, CGST/SGST/IGST split, the rate applied, exempt or composite items — AI explains the jargon, you own every number.
  3. 03Verify each rate against the official GST rate schedule (cbic-gst.gov.in or the GST portal) — link where you checked.
  4. 04Find and explain one oddity: a 5% item next to an 18% item, a bill with no GSTIN, service charge masquerading as tax.

What you’ll produce

4 deliverables

Submission standard

Submit the redacted bills, your decode table, the official rate source, and your oddity explanation. Include your AI workflow: your decoding prompts and any rate AI got wrong. Make sure each of the 5 photographed bills shows the shop name and date, and that every number in your decode table matches the figures visible on those bills.

  • The 5 real bills, redacted (one image)

    The 5 real bills, each showing the shop/vendor name, the date, and the GSTIN where present. Redact only personal data — the shop name, date and tax lines must stay visible.

    Image uploadRequired

  • Per bill: taxable value, tax split, rate — and the rate verified against the schedule

    Per bill, state the shop name and date, then taxable value, CGST/SGST/IGST split and rate — every figure must be readable on the matching photographed bill.

    Written responseRequired

  • The official source where you verified rates

    Public linkRequired

  • Your oddity: what looked wrong or weird, and the actual explanation

    Written responseRequired

You’ll complete these inside your private workspace.

How your work is evaluated

The passing benchmark is 70/100.

Decode accuracy

29%

The tax maths on all 5 bills is correctly decoded.

Officially verified

29%

Rates checked against the actual schedule, not assumed.

Detective work

14%

The oddity is real and its explanation is correct.

Numbers match the photographed bills

29%

Every decoded figure (taxable value, CGST/SGST/IGST, rate, total) matches a bill visible in the photo, and each bill shows a real shop name and date. If the analysis numbers can't be found on the photographed bills, or bills lack shop name/date, this fails.

How we grade your AI usage

30% of your score

Using AI is the point — it’s the skill this certificate proves. You’ll answer three short questions about how you used it: what you asked, what was wrong with its first answer, and what you changed. Specific, honest answers score high. “I pasted the brief and submitted the answer” scores near zero.
