When an NRI sells a property in India, TDS (tax deducted at source) calculation is done at the rate of 20.6 per cent on long-term capital gains and 30.9 per cent on short-term capital gains. However, the final taxation rate is similar for NRIs and resident Indians. If an NRI has a lower tax slab applicable to him, he can apply for a refund of the TDS by filing their income tax return.
