A clean monthly GST handover should not be a random folder of invoices. Send a sales register, purchase register, credit/debit notes, import/export records, reverse-charge expenses, marketplace reports, e-invoice/e-way records where relevant, prior-period correction list and any GST notices. Add one owner-approved summary of unusual transactions. That gives the preparer enough context to reconcile before filing.
Create one monthly folder structure
A consistent naming and cut-off process reduces repeated WhatsApp messages and forgotten documents.
Any GST-registered business working with an accountant or CA
The checklist should be tailored if you export, sell on marketplaces, use e-invoicing or have multiple GSTINs.
The first pack is often incomplete or not reconciled
A PDF invoice folder does not reveal whether all sales are included or which credit note belongs to which month.
The no-chasing document pack
Sales register; purchase register; sales/purchase credit/debit notes; bank/expense RCM list; imports; exports; marketplace reports; e-invoice/e-way records; fixed-asset transactions; prior correction list; notices; previous filed returns.
| Document | Why needed | Common problem |
|---|---|---|
| Sales register | GSTR-1 completeness | Cash/manual invoices omitted |
| Purchase register | 2B/ITC reconciliation | Duplicate or wrong GSTIN |
| Credit/debit notes | Adjust turnover/ITC | Notes posted in wrong period |
| Expense/RCM list | Reverse-charge review | Foreign/GTA/other covered expenses missed |
| Marketplace reports | Order/return/TCS reconciliation | Net settlement mistaken for sales |
| Prior issue log | Corrections | Same error repeated |
Day 1 close books → Day 2 send pack → exceptions list → reconciliation → tax preview → owner approval → filing → ARN/filed PDFs
Use your actual due dates rather than a generic calendar.
One foreign software invoice can change the filing
The accountant receives normal purchases but not the USD cloud-service invoice paid on a corporate card. That missing document can affect reverse-charge review and the return.
The filing may be complete from the preparer’s data but incomplete in reality
Repeated missing documents create corrections and weak accountability.
We return a pending-document list before filing
The process should show received items, missing items, reconciliation differences, proposed treatment and client approval.
What TargoLegal would ask for before filing or responding
The exact pack changes by issue, but these controls prevent the most common hand-off and accountability failures.
The proposed filing, payment, reversal, correction or response should be explained before submission. After filing, retain the ARN/filed PDF and any acknowledgement.
Do not make the problem harder to unwind
Reconcile books and source evidence before deciding tax treatment.
Use the exact period that created the mismatch, notice or filing obligation.
A correction should have a written bridge to the original error.
Save return PDFs, ARN, challans and the approved working.
What to send for a first review
Want a no-chasing monthly GST process? Send your business type and whether you have exports, e-commerce or e-invoicing. A tailored monthly document checklist can be mapped from that.
Related questions
What should I send first?
Send the GSTIN, exact tax period and the document or mismatch that triggered the question. That usually determines the rest of the checklist.
Should I pay before reconciling?
Do not make a blind payment merely because a portal difference appears. Establish the legal and factual basis first, unless an undisputed liability is already clear.
Can the GST Portal data be wrong or incomplete?
Portal data is essential evidence but it still has to be reconciled with books, supplier/customer records and the applicable law.
What should I keep after filing?
Retain the filed return PDF, ARN, payment evidence, reconciliation working and any client-approved summary of adjustments.
When should I involve a GST professional?
Professional review is advisable where the issue affects material tax, ITC, notices, refund, registration status, exports, e-invoicing or multiple return periods.
