FAQ

How should a founder decide between the old regime and the new tax regime when planning advance tax?

Compare slab outcomes with and without Chapter VI A deductions, run two computations each quarter, select the lower tax path based on your current year investments and business deductions, a CA managed service like AI Accountant can maintain both scenarios and update the choice before each installment to avoid 234B and 234C interest.

What is the cleanest quarterly close to keep AIS, TIS, and 26AS aligned for year end ITR?

How do finance heads minimise 271H risk on TDS returns during high volume months?

When do non residents need to file ITR in India if TDS is already deducted?

What documentation do banks usually ask for when remitting service fees outside India?

What happens if I deduct TDS but deposit after the 7th, and how should I account for the interest?

Interest under section 201 applies, one percent per month for delay from date of deduction to deposit, compute interest, deposit with the correct challan code, and tag it to the period of default, update books to recognise interest as an expense, and ensure the quarterly return reflects the challan to avoid mismatches.

What controls reduce AIS mismatches for founders with active trading accounts?

Monthly broker contract note reconciliation, quarter wise realised gain summaries, DP statements for corporate actions, and interest and dividend tie outs, ensure 26AS TDS on dividends is captured, and comment on AIS for duplicate or misclassified entries, this keeps the ITR computation defensible and refund processing smooth.

Is a dashboard actually useful for notice management or is email enough?

A dashboard with due date clocks, filing receipts, challans, and past submissions centralises context, reduces search time, and enforces maker checker, AI Accountant’s notice workspace attaches evidence, drafts replies, and tracks deadlines so the finance head has visibility and control without mail chains.

What is the fastest way to estimate quarterly advance tax for a bootstrapped company?

Start with year to date P&L, annualise cautiously, adjust for seasonality, add non operating items, subtract expected deductions, and apply current regime rates, net off TDS per 26AS, compute surcharge and cess, and set a buffer for volatility, a CA managed model automates this from books and 26AS to output the exact challan amount.
