Verify that your software vendor has integrated MFA-compliant API calls.<\/p>\n\n\n\n<p><strong>Step 4 \u2014 Reconcile Outstanding IRNs:<\/strong> All pending B2B invoices not yet uploaded to IRP must be regularized.

Ignoring the MFA activation deadline:<\/strong> Many businesses assume their existing login credentials remain valid. After October 2026, unactivated accounts face portal lockouts and cascading compliance failures.<\/p>\n\n\n\n<p><strong>2. ERP software not updated:<\/strong> Businesses using older Tally versions or custom-built billing software often face IRN generation failures at the point of invoice creation \u2014 discovered only during a GST audit.<\/p>\n\n\n\n<p><strong>3. ITC reversal risk:<\/strong> If your supplier fails to generate a valid IRN for a B2B invoice issued to you, <strong>you cannot claim Input Tax Credit<\/strong> on that purchase \u2014 even if GST was actually paid. This is one of the largest hidden financial risks in the current framework.<\/p>\n\n\n\n<p><strong>4. Cross-border OTP inaccessibility:<\/strong> Foreign nationals and NRI business owners managing <strong><a href=\"https:\/\/www.khannaandassociates.com\/international-taxation.html\">international taxation<\/a><\/strong> in India often cannot receive Indian OTPs abroad \u2014 a technical blockade that must be resolved proactively.<\/p>\n\n\n\n<p><strong>5. Documentation gaps:<\/strong> Businesses merging, restructuring, or operating through subsidiaries under <strong><a href=\"https:\/\/www.khannaandassociates.com\/holding-company-subsidiary-company.html\">holding company structures<\/a><\/strong> often have mismatched GSTIN registrations, creating system errors in IRN generation.<\/p>\n\n\n\n<p>Khanna &amp; Associates \u2014 serving clients from Jaipur, Dehradun, Delhi, and internationally \u2014 resolves all these challenges with structured legal and compliance advisory.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Expert_Tips_from_Senior_Advocates_at_Khanna_Associates\"><\/span>Expert Tips from Senior Advocates at Khanna &amp; Associates<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p><strong>Tip 1 \u2014 Proactive GSTN reconciliation before the deadline:<\/strong> Senior advocates recommend running a full ITC reconciliation in GSTR-2B versus purchase register for FY 2025-26 before October 2026. Unresolved mismatches become significantly harder to correct post-MFA enforcement.<\/p>\n\n\n\n<p><strong>Tip 2 \u2014 Use a GST Suvidha Provider (GSP) for MFA-compliant API access:<\/strong> Businesses generating high invoice volumes should engage a registered GSP rather than direct IRP API access, ensuring MFA protocols are met without operational disruption.<\/p>\n\n\n\n<p><strong>Tip 3 \u2014 Contractual protection clauses:<\/strong> Our <strong><a href=\"https:\/\/www.khannaandassociates.com\/agreement-lawyer.html\">agreement lawyers<\/a><\/strong> recommend embedding GST e-invoice compliance warranties into vendor and customer contracts \u2014 particularly for <strong><a href=\"https:\/\/www.khannaandassociates.com\/commercial-and-corporate-transactions.html\">commercial and corporate transactions<\/a><\/strong> \u2014 to protect ITC rights contractually.<\/p>\n\n\n\n<p><strong>Tip 4 \u2014 International investors entering India:<\/strong> Companies using <strong><a href=\"https:\/\/www.khannaandassociates.com\/foreign-direct-investments.html\">foreign direct investment<\/a><\/strong> routes or structuring through <strong><a href=\"https:\/\/www.khannaandassociates.com\/company-formation-setup-business-in-india.html\">company formation in India<\/a><\/strong> must build GST e-invoice compliance into their India entry framework from Day 1 \u2014 not as an afterthought.<\/p>\n\n\n\n<p><strong>Tip 5 \u2014 MSME-specific risk advisory:<\/strong> Smaller businesses newly crossing the \u20b95 crore threshold face a steep learning curve.

Who is mandatorily required to generate GST e-invoices in October 2026?<\/strong><br>Any registered GST taxpayer whose aggregate annual turnover (AATO) exceeds \u20b95 crore in any preceding financial year from 2017-18 onwards is mandatorily required to generate e-invoices through the IRP. This includes Indian companies, LLPs, and foreign company branches registered under GST in India. Non-compliance directly affects Input Tax Credit eligibility for buyers.<\/p>\n\n\n\n<p><strong>Q2. What happens if I don&#8217;t activate Multi-Factor Authentication (MFA) on the GST portal by October 2026?<\/strong><br>Failure to activate MFA will result in restricted or suspended GST portal access, preventing e-invoice generation, GSTR filings, and e-way bill creation. This can trigger cascading non-compliance, ITC reversals, and potential show cause notices from the GST department. Immediate activation is strongly advised. Contact Khanna &amp; Associates for guided assistance.<\/p>\n\n\n\n<p><strong>Q3. Can foreign companies and NRIs manage GST e-invoice compliance remotely?<\/strong><br>Yes, but with additional challenges. Foreign nationals and NRIs must ensure their Indian mobile numbers are active on GSTN for OTP delivery. International SIM access issues can block MFA login entirely. Khanna &amp; Associates \u2014 among the best law firms for NRI legal services in India \u2014 assists in resolving GSTN access and compliance structuring for cross-border clients remotely.<\/p>\n\n\n\n<p><strong>Q4. How does GST e-invoicing affect Input Tax Credit (ITC) for buyers?<\/strong><br>If your supplier generates a B2B invoice without a valid IRN, that invoice will not auto-populate in your GSTR-2B. This means ITC will not be available on that purchase \u2014 even if GST was paid. Buyers must proactively verify supplier e-invoice compliance before processing payments to protect their ITC. Our GST lawyers in Jaipur can assist with supplier compliance audits.<\/p>\n\n\n\n<p><strong>Q5.
