# How to Organise Transactions Made Before GST Registration ## Preserve the transaction history before changing it When GST registration is approved, keep the records created before approval intact. Sales bills, purchase invoices, stock movements, contracts and bank entries explain what actually happened while the business was unregistered or its application was pending. Do not rewrite all earlier documents as if the GSTIN existed from the business's first day. First establish the registration timeline: liability date where relevant, application date, grant date and effective date. A transaction before certificate issue can still fall within the effective registration period. Conversely, registration approval does not automatically turn every earlier expense into eligible input tax credit. ## Separate supplies from money received Create an outward-transaction schedule with customer, supply description, supply date, document number, value, collections and any later adjustment. Identify advances separately from completed supplies and retain the contract. The accounting label “receipt” does not decide whether an amount represents revenue, a deposit, a loan or owner capital. Reconcile cash, UPI, bank and marketplace collections to the underlying orders. A platform may settle a sale after registration even though the supply occurred earlier, and bank charges may reduce the payout. Use those facts to analyse the transaction rather than assigning the whole settlement to the payment date and calling it a new sale. For bills issued during a pending application, check whether the revised-invoice provision under section 31 applies to the effective-date-to-certificate interval. Follow the relevant conditions and time limit. Keep the original and any revised document connected so customers and the ledger do not record the same supply twice. ## Build a purchase schedule by category Separate inputs, input services, capital goods and items used personally or for exempt activities. Record invoice date, supplier GSTIN where applicable, taxable value, tax shown, payment and actual use. This classification is necessary because the special credit rules do not treat every pre-registration purchase alike. Section 18 provides different stock-credit reference dates for timely mandatory registration and voluntary registration. The covered categories include eligible inputs held in stock and inputs contained in semi-finished or finished goods on the relevant day, subject to conditions and restrictions. Do not treat that provision as a general reimbursement of all taxes paid before registration. The section also contains an invoice-age restriction for the specified special credit entitlement. Check it alongside the applicable rules, declaration and documentary requirements. A valid purchase invoice is necessary evidence, but it does not by itself establish the quantity still in stock, business use or eligibility under the correct subsection. ## Take a defensible stock snapshot Prepare an item-level stock statement for the date required by the relevant provision. Include quantity, location, purchase invoice linkage and tax information. For finished or semi-finished goods, retain a reasonable materials linkage rather than claiming the tax on the entire selling value as if it were purchase tax. Where no physical count was taken on that exact day, reconstruct the position from reliable opening stock, purchases, production and sales records, recording the method and uncertainties. Do not backdate a stock-count sheet or invent quantities to match the amount of credit the owner hopes to claim. Unresolved gaps should remain visible for assessment. Illustratively, a new retailer has ₹2 lakh of resale goods, a ₹60,000 laptop and three months of advertising bills before voluntary registration. The retailer should not add all invoice GST into one opening-credit claim. The resale stock, capital asset and consumed services need separate treatment under the applicable provisions and conditions. ## Keep mandatory and voluntary cases distinct A person applying within thirty days of becoming liable and subsequently obtaining registration has a different statutory stock-reference point from a person choosing voluntary registration. Record which route applies and why. If the mandatory application was late, do not silently use the timely-application entitlement without examining its conditions. The registration certificate and the turnover or event analysis should support the selected route. Where the owner initially believed registration was voluntary but the records reveal an earlier liability, resolve that issue before finalising opening tax records. A form selection does not change the underlying facts of supplies already made. Also review supplies made before the effective date where registration should have been obtained earlier. A later approval does not automatically settle that earlier period. Preserve the complete transaction schedule so liability, invoicing and any available remedy can be assessed accurately rather than hidden by an arbitrary accounting cut-off. Keep a separate list of documents the business has requested but not received. An expected corrected supplier invoice should not be treated as if it already exists. Mark the amount as unresolved and connect the later document to the original purchase so the eventual decision can be traced. ## Reconcile opening balances without double counting Match the purchase schedule to creditors, payments, stock and fixed assets. Distinguish the accounting cost from any credit that is actually eligible and validly claimed. If the tax remains part of cost because credit is unavailable, do not also create a tax-credit asset for the same amount merely to balance the opening ledger. Reconcile customer advances and receivables separately. A collection after registration may settle an earlier receivable, while a fresh order represents a different supply. Keep invoice references in bank matching so accounting staff do not post both the original sale and its later collection as turnover. Before filing any special credit declaration, check the current form, deadline, certification condition where applicable and evidence retained. Then preserve the acknowledgement and reconcile the amount to the electronic records and books. A supported pre-registration file leaves each transaction traceable and makes the first registered reporting period a controlled transition rather than an unsupported opening adjustment. ## Sources and references - [CBIC: Central Goods and Services Tax Act, consolidated through August 2021](https://cbic-gst.gov.in/pdf/CGST-Act-Updated-31082021.pdf) - [CBIC: CGST Rules, official compilation including registration amendment rules](https://cbic-gst.gov.in/pdf/10112020_CGST-Rules-2017_Part-A_Rules.pdf) - [GSTN: Applying for normal taxpayer registration](https://tutorial.gst.gov.in/userguide/registration/Apply_for_Registration_Normal_Taxpayer.htm) - [GSTN: Viewing the taxpayer profile and registration certificate](https://tutorial.gst.gov.in/userguide/taxpayersdashboard/My_Account_View_User_Profile.htm)
