I, SALARIES EMPLOYEE, ALREADY FILED INCOME TAX IN OLD TAX REGIME FOR FY.2021-23. FOR THE SAME FILED UPDATED INCOME TAX RETURN IN NEW TAX REGIME -
IS IT CORRECT
CAN I CHNAGE TAX REGIME IN UPDATED RETURN RELATED TO SALARY EMPLOYEE

what is due date for payment under section 43 B Liabities under income tax.

If amount of remittance is below 2,00,000 and purpose is for reversal or wrong entry S15002 so there is liability to deduct any TDS amount for same?

deductor filed 27q (for nri deductees) for q3, fy2425 yesterday,
but nri deductee 26as is not showing the tds amount.
how much time it will show in, any idea?
tds was 29 lakhs, hence worried.

Respected Experts

Kindly guide me that how many years records we have to keep in Income Tax & TDS.

Pan & Aadhar not linked while filing the 26QB return after filling got the demand notice to pay remaining 19% tax, what's the solution please let us know.

Please Suggest:
One Invoice Received as below:

Material Cost - 1,00,00,000.00
Installation Charges - 15,00,000.00

Total Invoice Value - 1,15,00,000.00 (Without GST)

Hence How much TDS will be applicable on above consolidated invoice and under which section?

Dear Experts,
If the assessee has income of 52 lakhs from Salary and other income and 3 lakh Short Term Capital Loss during the FY 2025, total income comes to 49 lacs though he will be paying tax on 52 lakh and carry forward loss to be setoff against capital gain in future. Is he liable to pay surcharge @ 10% on total tax payable?
This is for academic purpose.
Thanks in advance.
