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 produce4 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 each)

    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.

Output criteria

Decode accuracy

40%

The tax maths on all 5 bills is correctly decoded.

Officially verified

40%

Rates checked against the actual schedule, not assumed.

Detective work

20%

The oddity is real and its explanation is correct.

Required proof checks

Numbers match the photographed bills

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 usage30% 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.
