9 Things to Know Before Choosing a Tax Regime

Choosing between the old and new tax regime in India is now an annual decision for every salaried person. Pick wrong and you can leave 30,000 to 1,50,000 rupees on the table for that year. Pick right and the next 12 months of tax filing become noticeably simpler.

This is the 9-point checklist to run before you submit your declaration to your employer or file your return. Tick each one off in order. The right regime usually becomes obvious by item 6.

1. Know your annual gross income

Start with the basics. Pull your salary slip, add your fixed and variable pay, bonuses, and any other income for the financial year. The new regime has rebate slabs that wipe out tax up to a defined income level. Knowing your gross helps you decide whether you even need to compare regimes.

1. Salary plus perks plus bonuses
2. Interest income from FDs and savings
3. Capital gains, rental income, dividends
4. Any freelance or side income

2. Add up every deduction you can actually claim

The old regime wins when your eligible deductions are large. Add these in order:

1. Section 80C — PF, ELSS, life insurance, PPF, principal repayment
2. Section 80D — health insurance for self and parents
3. Section 24(b) — home loan interest
4. HRA — house rent allowance, if you live in rented property
5. LTA — leave travel allowance
6. Standard deduction — applies in both regimes now
7. Section 80CCD(1B) — 50,000 NPS additional

If your total real deductions cross roughly 4 to 4.5 lakh, the old regime is usually better. Below that, the new regime increasingly wins because of its lower slab rates.

3. Check whether your home loan interest is in play

Home loan interest deductions of up to 2 lakh under Section 24(b) are exclusive to the old regime for self-occupied property. If you are paying a large home loan EMI, this single deduction can swing the maths heavily toward the old regime.

Calculate the actual interest portion of your EMIs for the year, not the total EMI. The principal already counts under 80C, so do not double count.

4. Look at HRA exemption carefully

HRA exemption is also exclusive to the old regime. If you live in a metro and pay rent of 25,000 or more per month, the exemption can run into 2 to 3 lakh per year — a major old-regime advantage.

1. Calculate actual rent paid for the year
2. Compare 50 percent of basic salary in metros (40 percent in non-metros)
3. Take the lowest of HRA received, rent paid minus 10 percent of basic, and the slab above

5. Factor in life and health insurance premiums

Term plan and health insurance premiums get tax breaks under 80C and 80D respectively. Health insurance for parents above 60 unlocks an additional 50,000 deduction limit. These add up quickly for households supporting elderly parents.

Tax should never be the only reason to buy insurance, but if you are already paying premiums for sound coverage, capture them in your old-regime maths before you switch.

6. Review NPS contributions

NPS deductions live in two places under the old regime: 80CCD(1) within the 1.5 lakh 80C bucket, and 80CCD(1B) as a separate 50,000 limit. The new regime allows the 80CCD(2) employer contribution deduction only — typically up to 14 percent of basic for government employees, 10 percent for private sector.

If you contribute heavily to NPS, the old regime captures more of it. If you rely only on the employer match, the new regime's slab rates may still come out ahead.

7. Standard deduction is now available in both regimes

The 50,000 standard deduction (raised in some years) applies under both regimes for salaried individuals. Family pensioners get a separate amount. Do not skip the new regime under the old assumption that this benefit is missing — it is not, since the 2023 changes.

8. Compare the two regimes using the income tax calculator

Once you have your numbers, run them through the official income tax calculator on the Income Tax Department website. Enter the same gross income twice — once with all deductions, once without — and compare the tax payable.

1. The calculator handles slab rates and rebates automatically
2. It captures surcharge for income above 50 lakh
3. It accounts for cess

This step takes 5 minutes and removes guesswork.

9. Consider switching every year if your situation changes

Salaried taxpayers can switch between regimes every year. Business income filers can switch only once. So if you are salaried, treat the regime choice as an annual review tied to:

1. Income changes — promotion, job change, sabbatical
2. Big life events — home purchase, marriage, child birth, parental health
3. Insurance and investment changes
4. Rule changes — both regimes have been tweaked in nearly every Budget

Watch the surcharge thresholds

If your taxable income crosses 50 lakh, surcharge kicks in. The new regime caps the maximum marginal rate at 39 percent for very high incomes, while the old regime tops out at 42.74 percent. For incomes above 5 crore the gap is significant. High-income earners should run the calculation specifically against the surcharge slabs because the headline slab table understates total tax for both regimes.

Commonly missed items

1. Section 80EEA additional home loan interest deduction (legacy, only for older loans)
2. Section 80E education loan interest, with no upper limit
3. Section 80G donations to approved charities
4. Tuition fee for up to two children under 80C
5. Preventive health check-up of 5,000 within 80D

If you have any of these, recheck your maths because each one shifts the breakeven a bit further in favour of the old regime. For the calculator and rule details, the Income Tax Department portal is the authoritative source.
