Form 3CD Clause 44: Build the GST Expenditure Breakup for AY 2026-27
Clause 44 asks for an expenditure breakup by GST registration categories. A purchase-register export or GSTR-2B total is not a finished Clause 44 working paper: the expenditure population must first be established, classified and reconciled to the books. The Department's reporting summary identifies total expenditure and the split between registered and unregistered entities. Income Tax Department: items reportable in the tax audit report.
This guide covers the workpaper process for FY 2025-26 / AY 2026-27. Sources checked: 7 September 2026. Confirm final reporting treatment against the prescribed form, current utility and issued ICAI guidance.
Start with the reporting population, then classify suppliers
Export the detailed expense and purchase ledgers, fixed-asset additions and supplier master for the audit period. Record the entity, branches, period, export date and whether values include GST. Preserve an unedited copy.
Prepare a bridge from the books to the expenditure population used in Clause 44. Specifically identify capital purchases, inventory-related movements, journal provisions and reversals, depreciation, payroll and other non-supplier entries. These cannot be resolved simply by testing whether the ledger has a GSTIN.
For each adjustment, retain the amount, ledger reference, reporting treatment and supporting guidance. Use the issued Revised 2026 Guidance Note to resolve the detailed scope questions; an unexplained difference labelled “other expenses” is not a reconciliation.
A useful workpaper separates:
- source-ledger total;
- identified adjustments with reasons;
- expenditure accepted into the reporting population;
- supplier-category allocation;
- items still awaiting evidence or a reviewer decision.
The last category is a review queue. It should not become a convenient final reporting bucket.
The classification needs more than a valid-looking GSTIN
Within registered entities, the form distinguishes expenditure relating to exempt goods or services, composition suppliers and other registered suppliers. The registered total is then compared with expenditure relating to unregistered entities.
Keep supplier status evidence relevant to the transaction period. A supplier's status today may not establish its status when the expenditure arose. Equally, an empty GSTIN field in an old accounting master does not prove the supplier was unregistered.
| Source-data problem | Workpaper response |
|---|---|
| GSTIN is blank | Check invoice and supplier evidence; keep the item unresolved until supported |
| GSTIN format is valid but status is unclear | Verify the relevant registration and dates |
| Composition status changes during the year | Review expenditure by the applicable period |
| One supplier provides taxable and exempt items | Classify at the transaction level where required |
| Credit note appears in a different export | Link it to the underlying expense and explain timing |
| Expense journal has no supplier | Investigate the nature and reporting treatment separately |
Do not classify every purchase from a registered supplier as “other registered” without reviewing whether the exempt or composition category applies.
Worked example: make the totals explain themselves
Assume the reviewer has established a reportable expenditure population of ₹1 crore after documenting the books-to-report reconciliation. The example below illustrates only the classification arithmetic; it is not a rule for which ledger items belong in that population.
| Classification | Amount |
|---|---|
| Registered: exempt goods/services | ₹8 lakh |
| Registered: composition suppliers | ₹5 lakh |
| Other registered suppliers | ₹72 lakh |
| Total relating to registered entities | ₹85 lakh |
| Relating to unregistered entities | ₹15 lakh |
| Total reportable expenditure | ₹100 lakh |
The two controls are simple: ₹8 + ₹5 + ₹72 = ₹85 lakh, and ₹85 + ₹15 = ₹100 lakh. The harder control is proving that every underlying item appears once in the correct category.
Suppose ₹4 lakh initially classified as unregistered turns out to relate to an ordinary registered supplier. The unregistered amount becomes ₹11 lakh, other registered becomes ₹76 lakh and the overall total stays ₹100 lakh. The change belongs in the classification log, with evidence, rather than as a silent edit to the final table.
Why GSTR-2B will not close the workpaper for you
Use GST return data as a cross-check, while retaining the books as the starting population. A missing item in 2B can require investigation; it does not by itself establish an unregistered supplier. Credit eligibility, invoice reporting, timing and expenditure classification answer different questions.
Similarly, a registered supplier transaction does not automatically create eligible input tax credit. Keep the ITC reconciliation separate and cross-reference it where helpful. Combining the two can conceal the very differences the reviewer needs to understand.
Review checks before moving numbers into the utility
Reperform the category totals. Trace selected items from the source export into the final category and back again. Examine material manual overrides, unresolved supplier status, negative amounts and journals with no party details. Confirm that the approved version and the submitted table agree.
The Clause 44 GST expense breakup calculator can organise the categories and export a working table. The Clause 44 reconciliation template provides a place to retain the supporting work. Classification and scope decisions remain with the auditor.
Frequently asked questions
Is a blank GSTIN enough to classify expenditure as unregistered?
No. A missing field is a data-quality exception. Obtain evidence of the supplier's relevant status before making the final classification.
Should Clause 44 equal the purchase register?
Not automatically. Establish the reporting population and document its reconciliation to the books, including transactions outside the ordinary purchase register.
Can the difference between total expenditure and registered expenditure be plugged into unregistered expenditure?
Only a supported classification should reach that category. A residual amount can hide missing data, duplicates or scope errors; investigate it before concluding.
