ITR preparation is the engine behind every successful tax filing. Before a return can be submitted, someone must gather the documents, verify the numbers in the Annual Information Statement, compute the income under each head, apply the correct deductions and exemptions, calculate the tax liability under both old and new regimes, verify TDS credits, compute any outstanding advance tax or self-assessment tax, and populate every mandatory schedule in the correct format. When done by a Chartered Accountant, this process surfaces issues that self-filing typically misses — missed income, overclaimed deductions, misclassified gains, and AIS discrepancies.

The Income Tax portal's pre-filling facility creates an illusion of simplicity — it auto-populates salary, TDS, and some interest figures from Form 26AS. But it does not pre-fill capital gains correctly, it does not compute deductions, it does not choose between old and new regime, it does not handle foreign income, and it does not flag entries in the AIS that the taxpayer has not accounted for. Accepting pre-filled data without verification is one of the most common causes of Section 143(1) adjustments.

NDS Advisors prepares income tax returns for every category of taxpayer — from salaried individuals to NRIs, from sole proprietors to companies. Our preparation process includes a full document review, a line-by-line AIS reconciliation, schedule-by-schedule workings, regime optimisation, and a draft return presented for client approval before filing. Every computation is documented and retained on file.

Frequently Asked Questions

ITR preparation is the process of computing income, applying deductions, reconciling AIS data, and building all the schedules of the return — the complete workings. ITR filing is the act of submitting the prepared return on the income tax portal and e-verifying it. NDS Advisors handles both as a seamless end-to-end service.
For a straightforward salaried individual, preparation typically takes 1-2 working days once all documents are received. For taxpayers with capital gains, multiple income sources, or business income, 3-5 working days is typical. The draft is shared with you before filing, so allow a day for your review as well.
Mismatches between Form 16, Form 26AS, and AIS are common — and important to resolve before filing. Common causes include employer TDS filing errors, interest income captured by banks at different amounts, and capital gains reported at transaction date rather than settlement. We identify each mismatch, advise on the correct amount to report, and flag any discrepancies that require employer correction.
For AIS download and pre-fill review, portal access is helpful but not mandatory — you can download the AIS and share it with us, or we can access it through our CA portal. For filing, we require your login credentials or DSC. All credentials are handled with strict confidentiality and cleared from our systems after the filing is complete.
Core documents include PAN, Aadhaar, Form 16 (salary), Form 16A (TDS on other income), Form 26AS, AIS, bank statements for the full year, capital gains statements from your broker or mutual fund, investment proofs for deductions (LIC premium, PPF, ELSS, health insurance), rent receipts if claiming HRA, home loan statement if claiming Section 24(b), and property documents if you sold real estate.
