What Changed in 2026 — GST 2.0 and HSN Phase-3

Who Needs E-Invoicing

E-invoicingis mandatory for businesses with aggregate annual turnover above ₹5 crore inany financial year since 2017-18 — across all GSTINs under the same PAN. Thisthreshold has been in place since 1 August 2023 (CBIC Notification No.10/2023-Central Tax dated 10 May 2023). Once your turnover crosses ₹5 crore inany year, the mandate applies permanently — even if your turnover falls insubsequent years.

E-Invoice Cancellation — The 24-Hour Rule

Ane-invoice can only be cancelled within 24 hours of IRN generation. To cancelwithin 24 hours: open the invoice in Zoho Books → Actions → Cancel E-Invoice →select a reason. This cancels the invoice in both Zoho Books and the IRPsimultaneously.

After24 hours, the Cancel E-Invoice option is no longer available. You must cancelmanually on the GST portal, then return to Zoho Books and use Actions → Mark asCancelled to update the status. Cancellation is irreversible — the IRN cannotbe reactivated. To re-issue the invoice, use Actions → Clone Invoice to createa new invoice, then push it to the IRP to generate a new IRN.

How to Set Up E-Way Bills in Zoho Books

E-waybills are required for the movement of goods worth more than ₹50,000 in asingle consignment — for inter-state movement across India. Intra-statethresholds vary by state (some states have set limits up to ₹2,00,000).

Important: The 180-Day Rule (Effective 1 January 2025)

From 1January 2025, the NIC e-way bill portal blocks generation of an e-way billagainst any document (invoice, delivery challan, bill of supply) dated morethan 180 days before the generation date. If you attempt to generate an e-waybill against an old document, the portal returns error code 820. The maximumextension period is 360 days from the document date.

Forgoods that are being dispatched on a delay — manufacturing backlogs, storageperiods, or slow-moving stock — raise a fresh delivery challan dated at thetime of actual dispatch rather than using the original invoice date. Thisavoids the 180-day block entirely.

How to Configure TDS in Zoho Books India

TDS(Tax Deducted at Source) in Zoho Books is configured under Settings → Taxes →TDS. Enable TDS, add your TAN (Tax Deduction Account Number) in organisationsettings, and configure which transactions attract TDS deduction. Zohopre-creates common TDS sections — you can add custom rates for specificscenarios.

Common TDS Sections and Rates

Withouta valid PAN from the vendor, TDS is deducted at the higher rate — 20% for mostsections, or 5% under Section 194Q. In Zoho Books, if a vendor's PAN is notentered, the system automatically applies the higher rate.

How TDS Works in Zoho Books

AssignTDS sections to vendors under their Tax Info tab. When you create a bill for aTDS-applicable vendor, Zoho calculates the TDS automatically and shows the netamount payable to the vendor. The TDS amount is tracked separately in a TDSPayable liability account. TDS is deposited via Challan ITNS 281 by the 7th ofthe following month.

ForSection 194Q (purchase of goods), TDS applies only on the amount above ₹50 lakhpaid to a single vendor in a financial year. For example, if you pay a vendor₹60 lakh in the year, TDS at 0.1% applies on ₹10 lakh (the amount above ₹50lakh) — not on the full ₹60 lakh.

Wherea vendor holds a Section 197 lower or nil deduction certificate, set a customTDS rate on that vendor matching the certificate rate. Record the certificatenumber and validity period in the vendor's notes for audit reference.

TDS Returns

Zoho Books generates the data required for Form 26Q (quarterly TDS return fornon-salary payments) and Form 16A (TDS certificates issued to vendors). Exportthe data from Zoho Books and import it into your TDS return filing software(such as TDS-RPU from the Income Tax Department website) to prepare and filequarterly returns.

Common GST Setup Mistakes
in Zoho Books — and How to Fix Them

Wrong GSTIN Entry

Asingle wrong character in the GSTIN causes every e-invoice to be rejected andbreaks GSTR-1 B2B matching. Verify your GSTIN digit-by-digit atgst.gov.in/searchtaxpayer. Also check that the GSTIN is active — a suspended orcancelled GSTIN causes identical symptoms to a wrong one. For multi-statebusinesses, verify each branch GSTIN is assigned to the correct state in ZohoBooks.

Outdated Tax Rates After GST 2.0

Ifyour Zoho Books still has 12% and 28% tax rates configured and assigned toitems, your GSTR-1 data will show incorrect tax amounts for supplies made after22 September 2025. Review every item's assigned tax rate against the currentCBIC rate notifications and update to 5%, 18%, or 40% as applicable. Archivethe old rates after all items are updated.

HSN Codes Entered as Free Text

Typingan HSN code directly rather than selecting from the dropdown means it will be rejected when GSTR-1 is pushed to the GSTN under the Phase-3 mandate. Go toItems → filter by items with free-text HSN → re-enter each code by selectingfrom the system dropdown. For large catalogues, use the bulk CSV re-import withcodes in the correct column.

Wrong Place of Supply Configuration

The place of supply determines whether CGST+SGST or IGST applies. A wrong statecode charges the wrong tax and misreports your GSTR-1. For B2B supplies, theplace of supply is the buyer's GSTIN state. For B2C supplies, it is the buyer'sdelivery address state. If you are using Branches, verify each branch's GSTINis assigned to the correct state — Zoho uses this to auto-apply intra orinter-state tax.

Filing GSTR-3B Without Reconciling GSTR-2B

Claiming ITC on purchases not in your GSTR-2B results in a DRC-01C notice (automaticmismatch intimation) and forced ITC reversal with 18% per annum interest. PullGSTR-2B between the 14th and 18th of each month and reconcile before filingGSTR-3B on the 20th. Do not skip this step.

Not Recording GST Payment After Filing

After paying GST on the portal, recording the payment in Zoho Books (GST Filing → GSTPayment → Record Payment) is a separate manual step. If you skip it, your GSTPayable balance remains on your balance sheet indefinitely — overstating yourliabilities and confusing your CA at every review. Record the payment the sameday you pay it on the portal.

Pushing GSTR-1 With Failed Transactions

When GSTR-1 is pushed and some transactions show "Failed" status, filingwith failed transactions creates gaps between your books and the GSTN database.Fix all failed transactions (missing GSTIN, invalid HSN, tax rate mismatch) andre-push before filing. Failed transactions that are filed without fixing willcause ITC mismatches for your buyers.
