Individuals, HUFs, firms, companies, and other entities must file ITR if their income crosses prescribed limits or if specific conditions under the Income Tax Act apply (e.g., foreign assets, TDS refund claim, high-value transactions, etc.).

Common documents include:

• Form 16 or income statements
• Bank statements
• Investment proofs
• Capital gains details
• Books of accounts (if applicable)
• AIS/TIS and Form 26AS

Document requirements vary by taxpayer category.

• 26AS: A tax credit statement showing TDS/TCS, advance tax, and refunds.

• 26AS: AIS/TIS: Detailed income and transaction information available on the Income Tax portal. These are important for reconciliation while preparing an ITR.

Capital gains arise when a capital asset such as property, shares, or mutual funds is sold. The gain must be computed and reported while filing an ITR.

Advance tax is paid on estimated income during the financial year in specified installments if tax liability exceeds the threshold.

• GSTR-1: A monthly/quarterly statement of outward supplies (sales).
• GSTR-3B: A monthly summary return showing tax liability, ITC, and final GST payable.

GSTR-2B is an auto-generated statement showing ITC (Input Tax Credit) available from vendors. It is used to reconcile purchase records and determine eligible ITC.

Typically:

• Sales & purchase registers
• GST invoices
• Credit/debit notes
• GSTR-2B
• Books of accounts
• GST challans (if any)

ITC is the GST paid on purchases that can be claimed while paying GST on sales, subject to eligibility rules under the GST Act.

Due dates depend on whether the taxpayer files monthly or quarterly returns. GSTR-3B and GSTR-1 have different due dates as notified by GSTN.

TDS must be deducted when payments fall under applicable sections of the Income Tax Act, subject to thresholds and rates.
