Books of Account for Small Businesses: What to Keep for Tax Readiness
A tax-ready business is not one with perfect software; it is one that can explain receipts, expenses, assets, taxes and bank movements. The law has books and audit triggers, but practical readiness starts with basic records.
Core records to maintain
| Record | Why it matters |
|---|---|
| Sales invoices / receipts | Supports revenue and GST/TDS matching. |
| Purchase and expense invoices | Supports deduction and vendor trail. |
| Bank statements | Explains money movement and receipts. |
| Cash book, where applicable | Important for cash-heavy businesses and cash limits. |
| Asset register | Supports depreciation and sale/scrap treatment. |
Where tax audit connects
Official material on Section 44AB and tax audit reporting connects business records with audit reporting. If audit applies, the accountant will need much more than annual bank statements.
Monthly close checklist
- Lock invoices and receipts for the month.
- Reconcile bank receipts with sales/customer ledger.
- Book TDS/TCS credits and deductions.
- Reconcile GST returns where registered.
- Update asset and loan schedules.
