I'm working in corporate industry and TDS is deducted based on the new slab in this financial year, can I change the slab to old slab at the time of filing IT return and get the refund?
Ans: Yes. In case an employee does not choose the tax regime at the beginning of the financial year, the employer will deduct tax (TDS) under the existing tax regime. A salaried taxpayer can opt-in and opt-out every year. That means you can choose the new tax regime in one year and choose the regular tax regime in another year. They need not declare or intimate their choice to anyone at any time during the year.
You can always change between the new and old tax regime while filing your returns.
