Introduction to income tax return filing in India

Income tax return filing is how you report your income, taxes paid, deductions, and refunds due for a given year. You file for an Assessment Year, which evaluates the previous Financial Year. AY 2026 27 evaluates FY 2025 26, from 1 April 2025 to 31 March 2026. Filing correctly and on time enables refunds, loss carry forward, and smoother loan or visa checks, while late or incorrect filing can trigger interest and notices you would rather avoid.

If you prefer a steady hand, AI Accountant offers a CA led managed service with a live dashboard that tracks documents, deadlines, filings, and insights. We will show how that works later. For now, let us make your filing simple and correct. For detailed references and official help, see the e filing guides on ClearTax and the government portal’s ITR 1 instructions on incometax.gov.in.

File early, verify early, and keep proofs handy, this trio prevents most processing snags.

Mandatory filing even if below the threshold

Choose the right tax regime new or old

New regime highlights

• Lower slab rates from zero to thirty percent.
• A standard deduction of 75 thousand for FY 2025 26.
• Fewer exemptions and deductions, simpler compliance.

Old regime highlights

• Broader deductions, Section 80C up to 1 point 5 lakh, 80D for medical insurance, HRA for rent, and home loan interest under Section 24 up to 2 lakh for self occupied property.

How to opt

• New regime is the default while filing.
• To use the old regime, choose it during filing. If you have business or professional income, you may need to file Form 10 IEA to opt for the old regime or to switch back.

Quick scenarios

• Salaried with large 80C, HRA, and home loan interest, old regime often wins.
• Freelancers and consultants with few deductions, new regime often keeps tax and effort lower.

Fast rule of thumb, if your total deductions as a salaried person exceed about 3 point 75 lakh, the old regime may be better. Run the math before you decide. For a step by step setup, see this e filing guide or the ITR 1 help on incometax.gov.in.

Select the correct ITR form

FAQ

We are a VC backed startup with ESOPs and occasional SAFE conversions, which ITR should founders use and how do we handle ESOP taxation end to end

Founders with salary, capital gains, and possibly business income should evaluate ITR 2 versus ITR 3. If you draw only salary and capital gains, ITR 2 often fits. If you also have business or professional income, for example consulting or F and O, use ITR 3. ESOPs are taxed as perquisite at exercise in the old regime, on sale, the difference from exercise price is capital gain with the usual holding period rules. An AI enabled service like AI Accountant can map HR records, broker statements, and cap table data to create a clean perquisite and scrip wise capital gains working.

As a CA firm handling many salaried and freelancer clients, how do we quickly decide new versus old regime at scale

Build a baseline calculator that reads Form 16, rent details for HRA, housing loan interest, and Section 80C or 80D contributions, then compare with the new regime that includes the 75 thousand standard deduction for FY 2025 26. A quick rule, when deductions exceed about 3 point 75 lakh for a salaried person, the old regime tends to win. If the client has business or professional income, ensure Form 10 IEA requirements are met. AI Accountant’s scenario runs can automate this what if analysis and store the decision trail for each client.

For aggressive F and O traders and consultants, how do we classify income, do we need audit, and which ITR applies

F and O trading is treated as business income, reported in ITR 3. If turnover based on prescribed computation crosses audit thresholds, tax audit under Section 44AB may apply, with the 10 crore threshold available when cash receipts and payments are within five percent. Presumptive 44AD is not designed for derivatives trading. An AI Accountant workflow can fetch broker ledgers, compute turnover, and alert on audit triggers before the 31 October deadline.

How do we reconcile persistent AIS mismatches with our general ledger, and what documentation should we retain

First, match every AIS and TIS line item to ledger entries. Where reported items are incorrect, submit feedback in AIS marking them as disputed or corrected. For missing TDS, request the deductor to revise the TDS return so credits appear in 26AS. Retain bank certificates, contract notes, TDS certificates, and correspondence with deductors for at least six years. AI Accountant can keep a single source audit folder linking each AIS line to a voucher, document, or bank entry.

How should RSUs vested and sold overseas be reported for a resident, and how does DTAA relief apply

Report perquisite taxation on vest or exercise as per employer treatment, typically in salary. On sale, compute capital gains in INR using RBI reference rates. If foreign tax was paid, claim relief under the relevant DTAA in Schedule FSI and Schedule TR, maintaining broker statements, tax slips, and forex conversion proofs. A service like AI Accountant prepares FSI and TR with the necessary working papers and exchange rate trails.

Can a salaried employee file without Form 16 if HR is delayed, what data is sufficient

Yes, you can file using payslips, bank statements, AIS, TIS, and Form 26AS. Aggregate gross salary, taxable perquisites, and TDS as per 26AS. Reconcile any allowances and exemptions as visible in payslips. Many practitioners use AI Accountant to prefill from AIS and 26AS and then reconcile with payslip data when Form 16 is delayed.

What is the realistic refund timeline, and how do we avoid refund holds

Most refunds arrive one to three months after processing, provided the bank account is pre validated and e verification is completed within 30 days. Avoid mismatches between the name on PAN and bank, reconcile TDS credits to 26AS, and ensure outstanding demand issues are resolved. AI Accountant monitors refund status and flags Section 245 adjustments proactively.

Belated, revised, and updated returns, when should each be used and what are the cost implications

Use a revised return to correct errors before processing concludes, typically by 30 November. If you miss the original due date, file a belated return by 31 December with a late fee under 234F, and note that some losses cannot be carried forward. If you later discover under reported income, file an updated return ITR U within the permitted four year window, with additional tax and fees. AI Accountant keeps a change log so you can justify each revision.

For NRIs with India rent and NRO interest, which form and what to watch for on DTAA

Use ITR 2 if there is no business income, report rent net of municipal taxes and standard deduction, and report NRO interest. Claim TDS credits per 26AS and DTAA relief in Schedule TR if foreign taxes are involved. Keep tenancy agreements, interest certificates, and 26AS copies. AI Accountant streamlines NRO interest mapping and rent ledgers into ITR 2.

For a professional considering 44ADA, what are the limits, pitfalls, and audit considerations

44ADA generally applies up to seventy five lakh gross receipts subject to current rules, income is deemed at a prescribed percentage. Books and audit are not required if you follow scheme rules, but advance tax applies. Pitfalls include loss of the ability to claim actual expenses and constraints around loss carry forward. AI Accountant can simulate 44ADA versus regular books to reveal tax plus cash flow impacts before you opt in.

How do finance heads ensure that GST, TDS, and ITR data are consistent to reduce scrutiny risk

Perform cross module reconciliation, match outward supplies to revenue, TDS deducted to expense heads or payroll, and bank credits to invoices and AIS lines. Address timing differences with schedules and notes. AI Accountant’s dashboard ties GST returns, TDS statements, bank feeds, and the ITR draft into one reconciliation report that can be shared with auditors.

What operational advantages does an AI enabled Virtual Accounting partner provide versus standalone DIY tax software

DIY software computes and files, but you still chase documents, reconcile AIS, and manage notices. An AI enabled CA managed service like AI Accountant layers automated data ingestion, rules based reconciliations, and a human CA review, so you get clean books, on time ITRs, audit readiness, and tracked responses to 143 1 or 139 9 notices, all in one dashboard. This reduces rework and interest under 234B and 234C through better advance tax planning.
