# Advance Tax: Who Needs to Pay It, When, and How to Calculate It

> Learn advance tax calculation India rules: who must pay it, the four quarterly due dates, and the interest penalty under Section 234C if you fall short.

A freelance designer earning well above the taxable threshold assumed she could just pay her full tax bill in July when filing her return, the way many salaried employees mentally think about tax. She got a notice a few months later for interest under Section 234C, money she owed simply for not paying her tax on time during the year, not for owing tax itself.

Advance tax catches a lot of people off guard because it flips the usual order: instead of paying tax after the year ends, you're expected to estimate your income and pay tax on it in instalments throughout the year.

## Who needs to pay advance tax?[ #](#who-needs-to-pay-advance-tax)

Advance tax applies to anyone whose total tax liability for the year, after subtracting TDS already deducted, exceeds ₹10,000. This covers:

* **Freelancers and self-employed professionals**, since they don't have an employer deducting TDS on their income the way salaried employees do.
* **Business owners**, for the same reason.
* **Salaried employees with significant other income**, like capital gains, rental income, or interest, that isn't fully covered by TDS.

Salaried employees whose entire income is captured through employer TDS usually don't need to separately pay advance tax, since the deduction already happens monthly. Senior citizens (60 years or older) without any business income are exempt from advance tax obligations entirely.

## The four instalment due dates[ #](#the-four-instalment-due-dates)

Advance tax isn't paid as one lump sum. It's due in four instalments across the financial year, with a cumulative percentage of your estimated total tax liability due by each date:

| Due date     | Cumulative advance tax payable  |
| ------------ | ------------------------------- |
| 15 June      | 15% of estimated tax liability  |
| 15 September | 45% of estimated tax liability  |
| 15 December  | 75% of estimated tax liability  |
| 15 March     | 100% of estimated tax liability |

## Worked example: estimated tax liability of ₹1,50,000[ #](#worked-example-estimated-tax-liability-of-150000)

If you estimate your total tax liability for the year at ₹1,50,000, with no TDS credit to offset it:

* By 15 June: ₹22,500 (15%)
* By 15 September: ₹67,500 cumulative (45%)
* By 15 December: ₹1,12,500 cumulative (75%)
* By 15 March: ₹1,50,000 cumulative (100%)

Each payment is cumulative, meaning by 15 September you should have paid a total of ₹67,500 across both instalments so far, not an additional ₹67,500 on top of the June payment.

## What happens if you miss an instalment[ #](#what-happens-if-you-miss-an-instalment)

Section 234C charges interest at 1% per month for shortfalls in each instalment, calculated for a specific number of months depending on which instalment was missed. Section 234B additionally charges 1% per month if your total advance tax paid by 31 March is less than 90% of your actual final tax liability. These add up quickly, since even a delay of a few months on a meaningful shortfall generates real interest.

## Common mistakes with advance tax[ #](#common-mistakes-with-advance-tax)

1. **Assuming you only owe it if you're a business owner.** Freelancers, consultants, and anyone with substantial rental or capital gains income can trigger the same obligation.
2. **Underestimating income and getting caught by 234B/234C.** If your actual income turns out higher than estimated (a large freelance project lands late in the year, for instance), pay the additional advance tax in the next instalment rather than waiting until the final return.
3. **Forgetting to net off TDS already deducted.** Advance tax is calculated on your liability after subtracting any TDS credit you've already received, not your gross tax liability.
4. **Missing the 15 March deadline entirely** because it feels distant from the July return-filing deadline. This is the instalment most people accidentally treat as optional.

## Tips for managing advance tax smoothly[ #](#tips-for-managing-advance-tax-smoothly)

* **Re-estimate your income each quarter**, especially if you're a freelancer with variable income, and adjust the next instalment rather than waiting to true things up at year-end.
* **Set calendar reminders for all four dates**, not just the ones that happen to fall near a salary cycle or major expense.
* **Keep a buffer in a separate account** through the year so instalment payments don't compete with regular expenses when a due date arrives.
* **Use presumptive taxation (Section 44AD/44ADA) if eligible**, which can simplify advance tax obligations since only two instalments (by 15 March and, if needed, adjustments) generally apply under specific presumptive schemes.
* **Pay through the official e-filing portal using Challan 280** and keep the receipt, since this becomes your proof of payment when filing the annual return and claiming credit for what you've already paid.
* **Don't wait for a large payment to feel "worth it."** Even a modest shortfall in an early instalment accrues interest for every month it remains unpaid, so smaller, timely payments beat one large catch-up payment later.

## How advance tax interacts with your annual return[ #](#how-advance-tax-interacts-with-your-annual-return)

When you file your income tax return, the advance tax instalments you've already paid show up as tax credit against your final computed liability, alongside any TDS deducted during the year. If your instalments and TDS together cover your full liability, you owe nothing further at filing time. If they fall short, you pay the balance as self-assessment tax before filing, along with any applicable interest under Sections 234B and 234C for the shortfall during the year. Getting the quarterly instalments right isn't just about avoiding interest, it also means your July filing season is a formality rather than a scramble to find a lump sum.

Estimate your own instalment schedule with the [advance tax calculator](/advance-tax-calculator) before the next due date arrives. Check a similar scenario like [₹15,00,000 income under the new regime](/advance-tax-calculator/1500000-income-new-regime-advance-tax) or [₹15,00,000 income under presumptive taxation](/advance-tax-calculator/1500000-income-presumptive-advance-tax) to see how the numbers change based on your tax regime. If you're a freelancer weighing presumptive taxation, the [44AD vs 44ADA vs regular tax comparison](/44ad-vs-44ada-vs-regular-calculator) is worth checking too.

## Frequently asked questions[ #](#frequently-asked-questions)

### Do salaried employees need to pay advance tax?[ #](#do-salaried-employees-need-to-pay-advance-tax)

Usually not, since employer TDS already covers most of their tax liability through the year. However, if you have significant additional income, like capital gains or rental income, that pushes your total tax liability beyond ₹10,000 after TDS credit, you'll need to pay advance tax on that portion.

### What happens if I miss an advance tax instalment?[ #](#what-happens-if-i-miss-an-advance-tax-instalment)

You'll owe interest under Section 234C for the shortfall in that specific instalment, calculated at 1% per month for a set period. If your total advance tax paid by the end of the financial year falls short of 90% of your actual liability, Section 234B interest applies as well.

### Are senior citizens exempt from advance tax?[ #](#are-senior-citizens-exempt-from-advance-tax)

Yes, senior citizens aged 60 or above are exempt from advance tax obligations, as long as they don't have income from a business or profession. This exemption doesn't apply to super senior citizens with business income.

### Can I revise my advance tax estimate mid-year?[ #](#can-i-revise-my-advance-tax-estimate-mid-year)

Yes, and you should. If your actual income turns out different from your original estimate, adjust the remaining instalments accordingly rather than waiting until the final return to true everything up, since this reduces or eliminates interest penalties under Sections 234B and 234C.

Use the [advance tax calculator](/advance-tax-calculator) to work out your next instalment before the due date, so a preventable interest charge doesn't eat into money you already set aside for tax.
