FAQs

What is the ITR filing deadline for my entity type in AY 2026-27

For non audit cases, the ITR filing deadline is 31 July 2026. For cases that need audit, it is 31 October 2026. If you have transfer pricing, the deadline for the report is 30 November 2026. You can file a belated return by 31 December 2026 if you miss the original dates. Always verify on the Income Tax portal as dates may be extended.

How should a startup finance head structure the year end calendar to avoid last week crunch

Lock monthly closes within ten days, reconcile GSTR 1, GSTR 3B, and books every month, complete 26AS and AIS by May, and draft ITR computations in June. Use maker checker and a single repository for challans, acknowledgments, and schedules. An AI enabled Virtual Accounting service like AI Accountant can maintain deadlines on a live dashboard and alert you on anomalies.

What is 26AS, why is AIS relevant, and how do I reconcile both to my books

Form 26AS shows TDS and tax payments reported against your PAN. AIS lists a wider set of financial information like interest, dividends, securities, and foreign remittances. Export both, match line items to your ledger by party and date, raise follow ups for missing TDS credits, and document explanations for AIS variances. AI Accountant builds this tie out early and logs adjustments for audit.

Is GSTR 9C applicable for my turnover, and what evidence will my auditor ask for

Applicability depends on turnover thresholds and current year notifications. Your auditor will ask for the books to GSTR 9 reconciliation, revenue and ITC mappings, fixed asset schedules, and bank reconciliations. Keep a change log for post close adjustments. Always check current CBIC guidance and GSTN updates before you plan.

How do GSTR 1 and GSTR 3B mismatches occur, and what is the monthly control to prevent them

Mismatches come from timing differences, missed credit notes, or manual entry errors. Run a monthly tie out report that compares GSTR 1 outward supplies, GSTR 3B tax paid, and ledger revenue. Clear mismatches before quarter end so GSTR 9 preparation stays clean. AI Accountant automates this tie out and keeps a reconciliation log.

What is Form 12BB, and how does it reduce salary TDS leakage for employers

Employees submit Form 12BB with proofs of deductions and exemptions, for HRA, LTA, home loan interest, investments, and donations. This lets payroll compute accurate TDS, reducing over deduction and later refund issues. Collect proofs well before March, then lock payroll TDS for Q4.

Can a managed service issue tax audit certificates, or do I still need a statutory auditor

Managed services prepare the audit pack, but certification is done by your statutory auditor. Confirm scope early, agree on schedules, ledgers, and the timeline to deliver evidence. AI Accountant prepares a ready pack, then works with your auditor’s checklist.

How should founders think about data security for tax season documents

Use encrypted storage for bank statements, Form 26AS, AIS, and GST files. Implement minimum access rights, enforce maker checker approvals, and keep an audit trail of document access. Retain acknowledgments and schedules for the statutory period with clear tags for retrieval. Ask your provider to document their security posture.

What are typical pricing levers for year end tax filing services for SMEs

Monthly fees depend on transaction volume, number of bank and gateway accounts, and number of entities. Year end consolidation pricing covers reconciliations, schedules, GSTR 9 prep, and ITR. Add ons include payroll TDS, international tax, expat tax, and ROC events. Request a deliverables list and a shared compliance calendar to avoid scope drift.

How does an AI enabled Virtual Accounting service like AI Accountant reduce notice risk

By maintaining monthly hygiene, reconciling GSTR 1, GSTR 3B, and books, tying out 26AS and AIS early, and applying maker checker for returns. The dashboard flags anomalies, deadlines, and missing documents. A clean audit trail and a central repository make scrutiny easier and faster to resolve.

What should a CFO do in May and June to ensure on time ITR filing for non audit cases

Finalize 26AS and AIS reconciliation in May, complete GSTR tie outs and Q4 TDS returns, then draft the tax computation and get management approval in June. Arrange funds for tax payment and pre book filing slots. Keep acknowledgments and challans in one folder with clear naming.

Where do I verify statutory deadlines and potential extensions during the season

For ITR and TDS, check the Income Tax Department portal. For GST returns, check GSTN and CBIC updates. Non government summaries like ClearTax and TM Services are useful planning aids, but file only after confirming on official portals.
