A half-year close is a simple habit: before the busy October–November filing season, you check that your books for April to September are complete, matched to the bank and ready to support every return you file. If you do it once, you spend far less time fixing mismatches later. This guide gives Indian small businesses a practical half-year close checklist.
Why a half-year close helps
Most compliance work reads from your books. GST returns use your sales and purchase entries, TDS returns use your payment records, and your income tax return depends on a clean profit figure. If the books are messy at the half-year point, the same errors repeat in every return that follows.
Closing the half-year does not mean filing anything extra. It means taking a few hours to review what you already have, so that the returns due in the coming weeks, such as GSTR-1 for October 2026 and the TDS and TCS deposit, rest on reliable numbers.
Step 1: Reconcile every bank and cash account
Start with the bank. Compare the closing balance in your books on 30 September with the bank statement or passbook balance on the same date.
- List cheques you issued that have not yet cleared, and receipts you recorded that are not yet in the bank.
- Look for bank charges, interest and direct debits that you have not booked.
- Check that cash in hand in the books matches the physical cash count, not an estimate.
Any difference you cannot explain is worth chasing now. Small unexplained gaps usually turn out to be a missed charge, a duplicate entry or a receipt booked to the wrong customer.
Step 2: Match sales with what you reported
Go through your sales register for April to September and confirm that every invoice you issued is recorded once, with the right date, customer and tax split. Then compare totals with what you reported in your GST returns for the same months.
- Check for invoices raised but never entered in the books, and the reverse.
- Check that credit notes are linked to the original invoice and reported in the right period.
- Look for invoices with a wrong GSTIN or place of supply, which are easier to correct early.
If you find a difference, note which return period it belongs to and check the GST portal for the correction options available for that period before you change anything.
Step 3: Review purchases and input tax credit
Input tax credit is only as good as your purchase records. Compare your purchase register with the supplier invoices you hold and with the credit that shows in your GSTR-2B.
- Mark purchases that appear in your books but not in GSTR-2B, and ask the supplier whether they have filed.
- Mark credit that appears in GSTR-2B but has no purchase entry, which usually means a missing bill.
- Separate goods and services used for personal or exempt purposes, since credit rules may restrict them. Confirm treatment with your CA.

Step 4: Check payables, receivables and TDS
List what you owe and what you are owed on 30 September. For each unpaid supplier bill, check the due date and any payment terms. For customers, note which invoices are overdue and who needs a reminder.
If you deduct TDS, also confirm that the amounts deducted in each month match what you deposited, and that the deductee details such as PAN are recorded correctly. This prepares you for the quarterly return and for issuing certificates, covered in our post on Form 16A for July–September 2026.
Step 5: Look at stock, fixed assets and payroll
Three areas often hide errors until year-end:
- Stock: compare the stock register with a physical count of your main items and note shortages, damaged goods and slow-moving stock.
- Fixed assets: confirm that purchases of equipment are booked as assets and not as expenses, and that sales or disposals are recorded.
- Payroll: check that salary, PF and ESI entries match what you paid. See our PF and ESI checklist for October 2026 for the contribution dates.
Step 6: Run a trial balance and review the trends
Once the entries are cleaned up, take a trial balance as on 30 September and read it like a story. Compare it with the same period last year or with the previous half if you have it.
Ask simple questions. Did expenses jump in one head without a reason? Is a customer balance far larger than usual? Is any account that should be zero still carrying a balance? Each answer either confirms the books or points to an entry to fix.
Step 7: Organise your documents
Keep the supporting papers where you can find them in minutes: bank statements, supplier invoices, filed returns, payment challans and any notices. A simple folder for each month is enough. When a CA, a buyer or an officer asks for a document, you will not need to search for it.

Key takeaways
- A half-year close makes every later return easier, because it fixes errors while they are small.
- Reconcile bank and cash first, then sales, purchases, payables, receivables, stock and payroll.
- Read the trial balance for odd trends before you file.
- Keep documents organised by month, and confirm specific tax treatments with your CA.
