New vs old tax regime
Two ways to be taxed, and how to choose
In the last lesson we used Section 80C to lower the income that gets taxed. That works under one of India’s two tax regimes, and which regime you’re on decides whether deductions like 80C help you at all. So it’s worth understanding both.
The two regimes, in one line each
- Old regime. Relatively higher tax rates, but you can shrink your taxable income first with deductions and exemptions: Section 80C (up to ₹1.5 lakh), 80D for health insurance, HRA if you pay rent, home-loan interest, and more.
- New regime. Lower, more graduated tax rates and a higher tax-free starting point, but you give up almost all of those deductions. Salaried people still get a standard deduction.
The trade is simple to say: the old regime rewards you for the deductions you claim; the new regime just charges you less to begin with.
The new regime is now the default
If you do nothing and don’t pick a regime, you’re taxed under the new one. You can still choose the old regime if it works out cheaper for you. Most people compare once a year and pick.
When you actually choose
There are two moments. Early in the financial year your employer asks which regime to assume, so it can deduct the right amount of tax from your salary each month. Then, when you file your return, you confirm the choice.
Getting the first one wrong isn’t fatal, because the filing is what settles the final position. It does mean your monthly take-home was off all year, and you either overpaid and wait for a refund, or underpaid and settle up at the end.
How often you can switch
Broadly, a salaried person without business income can reconsider every year. That’s useful, because your own circumstances move. A year with a new home loan looks very different from the year before it.
Someone with business or professional income faces tighter rules, and generally gets only one chance to return to the new regime after leaving it. If that’s you, treat the decision as far more consequential and take proper advice.
How to choose: it’s arithmetic, not opinion
Add up the deductions you would actually claim in a year: 80C investments you really make, rent you really pay, a home loan you really have.
- If that total is large, the old regime’s deductions may outweigh its higher rates, so it can win.
- If you claim few deductions, the new regime’s lower rates usually leave you paying less, with far less paperwork.
Roughly: someone with a home loan and heavy 80C often lands on the old regime; someone who invests little and rents nothing often lands on the new one. But it’s your numbers that decide, not a rule of thumb.
The method, step by step
Do this once a year and the answer falls out:
- Write down your gross income for the year.
- List the deductions you’d genuinely claim under the old regime. Only the real ones, not the ones you might get around to.
- Work out your tax under the old regime: gross, minus those deductions, taxed at the old slabs.
- Work out your tax under the new regime: gross, minus only what’s still allowed, taxed at the new slabs.
- Compare the two numbers. The lower one wins.
The tax department’s own portal has a calculator that runs both sides, which saves you looking up the current slabs by hand.
Find your break-even
There’s a more useful way to think about it than a one-off comparison.
For any income, there’s a level of deductions at which both regimes cost exactly the same. Claim less than that and the new regime wins. Claim more and the old regime wins.
Once you know roughly where your own break-even sits, the annual decision becomes quick. You just ask whether this year’s genuine claims clear that bar. It also stops a specific mistake: investing more purely to “justify” the old regime, when the extra investment was never something you wanted.
Honest claims only
It’s worth stressing the word genuine. Counting a deduction you don’t actually qualify for, or rent you don’t really pay, doesn’t just risk a notice. It also produces the wrong regime choice, so you end up paying more tax than necessary as well as carrying the risk.
Where mutual funds fit
- ELSS and 80C only help under the old regime. Under the new regime an ELSS fund gives no tax deduction. You’d hold equity funds for their returns, not for a tax break.
- Tax on your fund gains is separate. The tax you pay when you sell fund units, short- and long-term capital gains, follows its own rules and is the same whichever regime you are on. It doesn’t change with this choice.
That second point matters more than it sounds. People sometimes assume moving regime changes everything about their tax. It changes how your salary and other ordinary income is taxed. It leaves your capital gains treatment alone.
Common mistakes
- Assuming the old regime is better because deductions feel like winning.
- Buying investments in March to justify a regime choice, rather than choosing based on what you’d invest anyway.
- Never revisiting the decision after a home loan, a move, a raise or a new dependant.
- Telling your employer one thing and filing another, then dealing with a refund or a shortfall.
- Using last year’s slabs to make this year’s decision.
The honest caveat
The exact tax slabs, the tax-free threshold, and the rebate are set fresh in each Union Budget and have moved several times in recent years, including changes that raised the income level at which the new regime charges no tax. This lesson deliberately teaches the structure rather than this year’s numbers, because those numbers date quickly.
Before you decide, check the current slabs for this financial year. The government’s own site, incometax.gov.in, is the primary source, or ask a tax professional.
Pair this with tax basics and Section 80C, or return to the money basics path.
This is general education, not financial advice, and not tax advice. Rules, rates and limits change every year; verify the current position before acting.
Questions people ask
Which regime am I on if I never chose one?
The new one. It's the default, so doing nothing puts you there. You can still opt for the old regime if it works out cheaper for you, but that's an active choice you have to make rather than something that happens automatically.
How do I decide which regime is cheaper for me?
Add up the deductions you'd genuinely claim in a year, then calculate your tax both ways using the current slabs and compare the two figures. It's arithmetic, not opinion. The official tax portal has a calculator that does both sides for you.
Do I still get any deduction under the new regime?
A few things survive, including a standard deduction for salaried people and the employer's contribution to the national pension scheme within limits. What goes is the long list of 80C, 80D, HRA and home-loan interest style claims. Check the current year's position.
Can I switch between regimes every year?
Broadly, a salaried person without business income can choose afresh each year. Someone with business or professional income faces tighter rules and can generally return to the new regime only once after leaving it. Confirm your own position before relying on this.
Does the regime change how my mutual fund gains are taxed?
No. Capital gains tax follows its own separate rules and works the same way under both regimes. The regime choice affects your salary and other ordinary income, not how a fund redemption is taxed.
Is ELSS still worth holding under the new regime?
Only on its investment merits. Under the new regime an ELSS fund gives no deduction, so the tax reason disappears and you're left with an equity fund carrying a three-year lock-in. If you want equity exposure, a fund without a lock-in may suit you better.
I pay high rent and have a home loan. Which regime suits me?
Often the old one, because rent and home-loan interest are exactly the large claims the old regime rewards. But run the numbers rather than assuming. The answer turns on how big those claims are relative to the rate difference.
Where do I check the current slabs?
incometax.gov.in, the income tax department's own site. Slabs, the rebate threshold and the standard deduction get revisited in each Union Budget, so a figure that was right last year may not be right now.
