Hi @john_wise,
The way you plan your taxes will primarily depend on the regime you opt for. While with the new tax regime, the itemized deductions might have been taken away, it offers more disposable income and the freedom to pick up investments of choice. Whereas, under the old tax regime, you can continue to make tax-saving investments and expenses and claim these deductions to bring down your total taxable income.
We recently released a video around the old and new tax regimes, where we talk about both the regimes in detail so you can make a calculated decision while opting for a regime.
You can also use the Tax Dashboard to understand your tax liability under both regimes.
Hope this helps
