What Advance Tax Is and Why It Matters

Advance tax is the income tax you pay as you earn through the year, rather than in one lump sum after the year ends. The principle is simple: the government wants its tax in step with your income, so if your total tax for the year is likely to be significant, you must estimate it in advance and pay it in installments across four due dates.

Miss those dates or underpay, and you face interest charges that quietly add to your bill. For salaried people whose employer deducts TDS, advance tax often takes care of itself, but the moment you have meaningful income outside salary, freelance earnings, capital gains, rent, interest, or business profit, advance tax becomes your responsibility.

This calculator does the whole job. You enter your estimated income for the year, your income type, and any TDS already being deducted, and it computes your actual tax under the current new regime, complete with the rebate, cess and surcharge, then nets off your TDS, checks

whether you cross the threshold that makes advance tax compulsory, and lays out exactly how much to pay by each of the four due dates. It also handles the special cases: the single-installment rule for presumptive taxpayers and the full exemption for senior citizens without business income.

The trigger is ten thousand rupees. You must pay advance tax only if your estimated tax for the year, after subtracting the TDS and TCS that will be deducted, comes to ten thousand rupees or more. Below that, you simply settle any balance as self-assessment tax when you file, with no advance tax obligation and no interest. This calculator applies that test automatically, so it tells you clearly whether you need to pay advance tax at all before showing you the schedule.

The Four Due Dates and How Much to Pay

For most taxpayers, advance tax is paid in four installments through the financial year, and the amounts are set as cumulative percentages of your total estimated tax. Understanding this cumulative structure is the key to paying the right amount at each stage.

The Installment Schedule

The schedule under Section 211 requires you to have paid at least fifteen percent of your tax by the fifteenth of June, forty five percent by the fifteenth of September, seventy five percent by the fifteenth of December, and the full hundred percent by the fifteenth of March. These are cumulative, so by September you should have paid forty five percent in total, not an extra forty five percent.

In practice this means paying fifteen percent in the first installment, then thirty percent, then thirty percent, then the final twenty five percent. If a due date falls on a Sunday or public holiday, the payment is due on the next working day.

The June and September Tolerance

There is a useful concession built into the rules for the first two installments. No interest under Section 234C is charged if you have paid at least twelve percent of your tax by the fifteenth of June, and at least thirty six percent by the fifteenth of September, even though the prescribed cumulative figures are fifteen and forty five percent.

This small tolerance recognises that estimating income early in the year is hard. For the December and March installments, however, there is no tolerance: you must reach seventy five percent and one hundred percent exactly, or interest applies on the shortfall.

How Your Advance Tax Is Calculated

The amount you pay is built up in clear steps, starting from your estimated income and ending with the net figure to be split across the installments. This calculator performs each step for you, but knowing them helps you check the result.

From Income to Tax

First, your estimated total income for the year is reduced by the standard deduction if you earn salary or pension, seventy five thousand rupees under the new regime. The slab rates are then applied to the resulting taxable income. Under the new regime for the current year, income up to four lakh is nil, the next four lakh is taxed

at five percent, and the rate steps up through ten, fifteen, twenty and twenty five percent to thirty percent on income above twenty four lakh. The Section 87A rebate can bring the tax to zero for taxable incomes up to twelve lakh. A four percent health and education cess is added, along with a surcharge if your income is high.

Netting Off TDS

Once your total tax is known, you subtract the TDS and TCS that has been or will be deducted during the year, because that tax is already being collected on your behalf. The figure that remains is your advance tax liability. Crucially, the ten thousand rupee threshold is tested on this net

amount, not on your gross tax, so if enough tax is already being deducted at source, you may fall below the threshold and owe no advance tax at all. This is why salaried people with tax fully covered by TDS often have nothing to pay, while those with large non-salary income do.

The Special Cases: Presumptive and Senior Citizens

Two groups of taxpayers follow different rules, and getting them right avoids either overpaying, in effort, or facing unexpected interest. This calculator handles both automatically when you tick the relevant box.

Presumptive Taxpayers Pay Once

If you have opted for the presumptive taxation scheme under Section 44AD, for small businesses, or Section 44ADA, for professionals such as freelancers, doctors and consultants, you enjoy a big simplification. Instead of four installments, you pay your entire advance tax in a single installment by the fifteenth of March.

There is no requirement to estimate or pay anything at the June, September or December dates, and no Section 234C interest applies for those quarters. This is a real convenience for small businesses and independent professionals, letting them settle their advance tax once a year rather than tracking four deadlines.

Senior Citizens May Be Exempt

A resident senior citizen, aged sixty or above, who has no income from business or profession is completely exempt from advance tax under the proviso to Section 207. Such a person can pay any tax due as self-assessment tax when filing the return, with no interest under Sections 234B or 234C.

This exemption recognises that retired seniors living on pension, interest and similar income should not have to navigate quarterly advance tax. Note the condition carefully: if a senior citizen has any business or professional income, the normal advance tax rules apply to them like anyone else, so the exemption is lost.

Tick the boxes that apply to you. If you select senior citizen without business income, the calculator marks you exempt. If you select presumptive taxation, it collapses the schedule to a single March installment. These options materially change what you owe and when, so setting them correctly is essential to getting an accurate schedule rather than a generic four-installment plan that may not apply to you.

Key rules at a glance: advance tax applies when net tax after TDS is ten thousand rupees or more. The standard deduction under the new regime is seventy five thousand for salary and pension. The Section 87A rebate makes tax nil up to a taxable income of twelve lakh. A four percent cess applies on top, and a surcharge applies above fifty lakh. Interest for late or short payment is charged under Sections 234B and 234C at one percent per month, which our dedicated interest calculator can work out for you.

Advance Tax Versus Self-Assessment and TDS

People often confuse the three ways income tax reaches the government, and understanding how advance tax differs from TDS and self-assessment tax clears up much of the confusion about who owes what and when.

How the Three Differ

TDS, tax deducted at source, is collected by whoever pays you, your employer on salary, a bank on large interest, a tenant on high rent, and remitted to the government before the money reaches you. Advance tax is tax you calculate and pay yourself, in installments during the year, on income where enough is not being deducted at source. Self-assessment tax is the final balancing payment you make when filing your return, if anything is still owed after TDS and advance tax. All three reduce your final liability; they differ only in who pays and when. Advance tax fills the gap between what TDS collects and what you actually owe, spread across the year.

Why the Distinction Matters

The practical consequence is that relying on TDS alone is risky if you have substantial non-salary income, because TDS may not cover your full liability, leaving a gap that advance tax is meant to fill. If you ignore that gap and wait to pay everything as self-assessment tax at filing, you face interest under Sections 234B and 234C for not having paid advance tax during the year. The system is designed so that tax flows in as income is earned, and the interest charges exist precisely to discourage deferring everything to the end. Knowing which of your income streams are covered by TDS and which are not is the first step to getting advance tax right.

A simple mental model: add up all your expected income, work out the total tax, subtract what TDS will collect, and if the remainder crosses ten thousand rupees, that remainder is your advance tax, to be paid in installments. Anything still left at filing is self-assessment tax. This calculator handles the first two steps for you and shows the installments, so you can see clearly how much of your tax is your own responsibility to pay in advance versus what TDS already covers.

Common Advance Tax Mistakes to Avoid

Because advance tax rests on estimation and self-discipline, the same errors recur every year, and each one usually ends in avoidable interest. Knowing them helps you stay on the right side of the deadlines.

Ignoring Side Income Until Filing

The most frequent and costly mistake is treating salary TDS as the end of your tax obligation while quietly accumulating untaxed side income, freelance fees, capital gains, interest, or rent, through the year. When filing time comes, the tax on that income is due all at once, plus interest under Sections 234B and 234C for not having paid it in advance. The fix is to review all your income sources at the start of the year and at each due date, not just your salary, and to pay advance tax on anything TDS does not cover. A few minutes of checking each quarter prevents a nasty year-end surprise.

Forgetting to Revise After a Windfall

Advance tax is an estimate, and life changes it. A mid-year bonus, a big capital gain, a new client, or a rent increase all raise your liability, yet many taxpayers set their installments early and never revisit them. If your income jumps, your remaining installments must rise to keep your cumulative payments on target, or you fall short and incur interest. Whenever something material changes your income, recompute your advance tax with the new figure and adjust your next payment. The cumulative installment structure is built to absorb these revisions, but only if you actually make them.

Missing the December and March Precision

The forgiving twelve and thirty six percent tolerance for June and September lulls some taxpayers into thinking the later installments are equally flexible. They are not. By December you must have paid seventy five percent exactly, and by March the full hundred percent, with no tolerance, or interest applies on the shortfall. Treating the December and March deadlines with the same looseness as the early ones is a common way to incur interest on what feels like a small miss. Mark those two dates firmly and ensure your cumulative payments hit the exact targets, because there is no cushion at the back end of the year.

The safeguard: at the start of the year estimate your full income and set a rough installment plan, then before each of the four due dates recompute with your latest actual figures using this calculator, and pay to hit the cumulative target. This simple quarterly discipline, reviewing income and recomputing four times a year, is all it takes to pay the right advance tax on time and avoid every rupee of Section 234B and 234C interest.

Deepak earns twenty lakh, mostly salary but with rental income his employer does not tax. His employer deducts one and a half lakh of TDS on the salary, but the rent leaves a net tax well above the ten thousand threshold, so he must pay advance tax on the balance.

The calculator computes his tax under the new regime, subtracts the TDS, and splits the remaining net advance tax across the four due dates, fifteen percent by June, forty five by September, seventy five by December, and the rest by March, so he pays on time and avoids interest.

Takeaway: Non-salary income not covered by TDS usually pushes a salaried person into paying advance tax.

he does not have to pay it in advance installments; he can simply pay it as self-assessment tax when he files his return, with no interest under Sections 234B or 234C. When he ticks the senior citizen box and leaves business income unchecked, the calculator confirms his exemption at once.

Takeaway: A resident senior with no business income is fully exempt from advance tax.

Six Expert Tips for Managing Advance Tax

01

Estimate Your Income Honestly Early

The whole system rests on estimating your annual income before the year is over, which is hard but important. Underestimate and you underpay, triggering interest; overestimate and you tie up cash unnecessarily. Make your best honest projection at the start of the year, including expected freelance income, capital gains,

rent and interest, and revise it at each due date as your actual earnings become clearer. It is far better to pay a little extra early and adjust down than to face a large shortfall and interest at year end, so err slightly toward caution in your first estimate.

02

Do Not Forget Non-Salary Income

The most common reason salaried people unexpectedly owe advance tax is income their employer does not tax through TDS: rent from a property, interest on fixed deposits above the TDS threshold, capital gains on shares or property, dividends, or freelance work on the side. Your salary TDS covers only your salary.

Add up all your other income, work out the tax on it, and if the total net tax crosses ten thousand rupees, you must pay advance tax. Checking this early, rather than discovering it at filing time with interest attached, is one of the most valuable habits a taxpayer can build.

03

Use the June and September Tolerance

Because income is genuinely hard to predict early in the year, the rules forgive a small shortfall in the first two installments: paying at least twelve percent by June and thirty six percent by September avoids interest even though the targets are fifteen and forty five percent. Use

this breathing room sensibly, but do not rely on it for the later installments, where seventy five and one hundred percent must be met exactly. Treat the tolerance as a cushion for early-year uncertainty, not as a licence to routinely underpay, since the December and March deadlines are strict.

04

Account for Capital Gains When They Occur

Capital gains are unpredictable, so the law does not expect you to have estimated them in advance. If you make a capital gain, you are required to pay the advance tax on it in the installment falling due after the gain arose, and no interest applies for not having anticipated it earlier.

So if you sell shares or property in December, include that gain in your December or March installment. Track the timing of your gains through the year and slot the tax into the correct installment, rather than either paying too early or missing it and facing avoidable interest.

05

Pay Online and Keep the Challan

Advance tax is paid through the income tax e-filing portal or authorised bank channels using a challan, and the payment reflects against your PAN in Form 26AS and the annual information statement. Always pay online for a clean record, note the challan identification number, and

keep the receipt, because you will need these details when filing your return to claim credit for the advance tax paid. Reconcile your payments against Form 26AS before filing, so any mismatch is caught and corrected early rather than delaying your refund or triggering a notice.

06

Know Your Interest Exposure If You Miss

If you underpay or miss an installment, interest is charged under Section 234C on the shortfall in each installment, and under Section 234B if your total advance tax paid by the year end is less than ninety percent of your assessed tax. Both run at one percent per month. Knowing this

exposure helps you decide whether a small top-up now is worth avoiding months of interest later. If you have already missed a payment, work out exactly what interest you owe using our dedicated 234A, 234B and 234C interest calculator, so you can pay the correct amount and stop the interest clock.

Frequently Asked Questions on Advance Tax

Who has to pay advance tax?
Any taxpayer, whether an individual, Hindu Undivided Family, firm or company, whose estimated tax for the financial year comes to ten thousand rupees or more after subtracting TDS and TCS must pay advance tax under Section 208. In practice this most often applies to freelancers, business owners, professionals, and salaried individuals who have significant income outside their salary, such as rent, fixed deposit interest, capital gains or dividends, that their employer does not tax through TDS. If your entire tax is already covered by TDS and the remaining net tax is below ten thousand rupees, you do not have to pay advance tax and can settle any balance when you file.
What are the advance tax due dates?
For most taxpayers, advance tax is paid in four installments with cumulative targets: at least fifteen percent of your total tax by the fifteenth of June, forty five percent by the fifteenth of September, seventy five percent by the fifteenth of December, and the full hundred percent by the fifteenth of March. Because they are cumulative, this works out as paying fifteen percent, then thirty, then thirty, then the final twenty five percent across the four dates. If a due date falls on a Sunday or public holiday, payment is due the next working day. Taxpayers under the presumptive scheme instead pay everything in one installment by the fifteenth of March.
How is advance tax calculated?
You start by estimating your total income for the year and reducing it by the standard deduction if you earn salary or pension. Slab rates are applied to the taxable income to get the base tax, the Section 87A rebate is applied where eligible, and then a four percent cess and any surcharge are added to reach your total tax. From this you subtract the TDS and TCS being deducted during the year, and the remainder is your advance tax liability. If it is ten thousand rupees or more, you split it across the four installments by the prescribed cumulative percentages. This calculator performs every one of these steps for you automatically.
What is the ten thousand rupee threshold?
Under Section 208, advance tax is compulsory only if your estimated tax liability for the year, after crediting the TDS and TCS that will be deducted, is ten thousand rupees or more. The threshold is tested on this net figure, not on your gross tax before TDS. So a salaried person whose salary tax is fully covered by employer TDS may have a net figure below ten thousand and owe no advance tax, while someone with large untaxed income will cross it. If you are below the threshold, you simply pay any remaining tax as self-assessment tax at filing time, with no advance tax obligation and no interest.
How does advance tax work for freelancers?
Freelancers and independent professionals usually have no employer deducting TDS on most of their income, so they are among the most common advance tax payers. If you have opted for the presumptive taxation scheme under Section 44ADA, available to professionals such as designers, doctors, lawyers and consultants, you get a big simplification: you pay your entire advance tax in a single installment by the fifteenth of March, with no need to pay at the earlier three dates. If you have not opted for presumptive taxation, you follow the normal four-installment schedule. Either way, since your income is not covered by salary TDS, advance tax is usually your responsibility.
Do senior citizens have to pay advance tax?
A resident senior citizen, aged sixty or above, who does not have any income from business or profession is fully exempt from advance tax under the proviso to Section 207. Such a person, typically living on pension, interest and similar income, can pay any tax due as self-assessment tax when filing the return, with no advance tax installments and no interest under Sections 234B or 234C. The condition is important, though: if a senior citizen earns any business or professional income, the exemption does not apply and the normal advance tax rules apply to them like any other taxpayer. This calculator applies the exemption when you indicate you are a senior with no business income.
What is the presumptive taxation exception?
Taxpayers who have opted for the presumptive taxation scheme, under Section 44AD for small businesses or Section 44ADA for professionals, pay their advance tax differently. Instead of four quarterly installments, they pay the entire estimated advance tax in a single installment by the fifteenth of March of the financial year. There is no requirement to pay anything at the June, September or December due dates, and no Section 234C interest is charged for those quarters. This is a significant convenience, letting eligible small businesses and independent professionals settle their advance tax once a year. If you tick the presumptive box, this calculator shows just the single March payment.
What is the interest for missing advance tax?
Two sections charge interest, both at one percent per month or part of a month. Section 234C charges interest for deferring or short-paying an individual installment during the year, computed on the shortfall, for three months on each of the first three installments and one month on the last. Section 234B charges interest if the total advance tax you paid by the end of the year is less than ninety percent of your assessed tax, running from the first of April of the assessment year until you pay. These add up quickly, so paying on time matters. To calculate the exact interest on a shortfall, use our dedicated 234A, 234B and 234C interest calculator.
Is the June or September tolerance real?
Yes. The rules include a genuine concession for the first two installments to allow for the difficulty of estimating income early in the year. No Section 234C interest is charged if you have paid at least twelve percent of your total tax by the fifteenth of June, and at least thirty six percent by the fifteenth of September, even though the prescribed cumulative targets are fifteen and forty five percent. This means a small shortfall in the first two installments is forgiven. However, there is no such tolerance for the December and March installments, where you must reach seventy five percent and one hundred percent exactly, or interest applies on the shortfall.
How do I pay advance tax?
Advance tax is paid online through the income tax e-filing portal or through authorised bank channels, using a challan. You select the assessment year, the type of payment as advance tax, enter the amount, and pay through net banking, a card, or over the counter at an authorised bank. The payment reflects against your PAN and appears in your Form 26AS and annual information statement. Always keep the challan identification number and receipt, because you will need them when filing your return to claim credit for the advance tax you paid. Reconcile your payments against Form 26AS before filing to catch any mismatch early.
Does advance tax differ under the old and new regimes?
The advance tax rules, the due dates, the installment percentages, the ten thousand threshold and the exemptions, are the same under both the old and the new tax regimes. What differs is the tax computation itself, because the two regimes have different slab rates and different treatment of deductions. Under the new regime you get the standard deduction but few other deductions, while the old regime allows deductions like 80C, 80D and home loan interest but taxes at higher rates. Your advance tax liability follows whichever regime you choose for the year. This calculator computes the tax under the new regime, which is the default for most taxpayers.
What happens if I pay more advance tax than needed?
If you pay more advance tax than your final assessed liability, the excess is refunded to you when you file your income tax return, and the department pays interest on the refund under Section 244A in many cases. So overpaying is not lost money, though it does mean your cash was tied up with the government for a while when it could have been earning elsewhere. This is why a reasonable estimate matters: paying roughly the right amount avoids both the interest for underpaying and the opportunity cost of significantly overpaying. A modest cushion is sensible, but a large overpayment simply delays access to your own money until the refund arrives.
Do I pay advance tax on capital gains?
Yes, capital gains are subject to advance tax, but the rules recognise that you cannot predict them in advance. You are required to pay the advance tax on a capital gain in the installment that falls due after the gain actually arose, and no interest is charged for not having anticipated it in an earlier installment. So if you sell shares or property in December, you include the tax on that gain in your December or March payment. This sensible treatment means an unexpected gain late in the year does not retroactively make your earlier installments short. Track when your gains occur and slot the tax into the correct following installment.
Can I revise my advance tax estimate during the year?
Yes, and you should. Advance tax is based on an estimate, and your income picture becomes clearer as the year progresses, so you revise your estimate at each due date and adjust your payment accordingly. If your income turns out higher than expected, you increase your later installments to catch up; if lower, you reduce them. The cumulative structure of the installments naturally accommodates this, since each date has a cumulative target rather than a fixed amount. Recompute with your updated income figure before each due date, which this calculator makes easy, so your payments track your real earnings and you neither underpay nor overpay significantly.
How accurate is this calculator?
This calculator applies the current new regime slab rates for the financial year 2025-26, the Section 87A rebate, cess and surcharge, nets off your TDS, tests the ten thousand rupee threshold, and produces the correct installment schedule under Section 211, including the presumptive single-installment case and the senior citizen exemption, so it is a reliable estimate for planning your advance tax. However, it computes tax under the new regime and uses a simplified surcharge treatment, and your actual liability depends on your full income details and regime choice. Use it to plan your installments, then confirm your exact figures with the income tax portal or a tax adviser before paying.
Is my data private when I use this tool?
Yes. Every calculation runs entirely inside your own browser using standard arithmetic. The income, TDS, and other figures you enter are never sent to a server, never stored, and never shared, and you do not need to register or log in. When you download a PDF report or share a result on WhatsApp, that happens locally on your device and only with recipients you choose. This privacy-first design means you can plan your advance tax with your real income figures in full confidence that your financial details stay entirely on your own device and nowhere else, unlike portals that require you to log in and submit your data.
Which authority governs advance tax?
Advance tax is governed by the Income Tax Act, administered by the Income Tax Department and the Central Board of Direct Taxes. The liability arises under Section 208, the installment schedule under Section 211, and the interest for default under Sections 234B and 234C. Payment is made through the official income tax e-filing portal. For obligations arising in later years under the new Income Tax Act 2025, the equivalent provisions are renumbered, though the substance continues. For authoritative information and to make payments, refer to the Income Tax Department portal and the Central Board of Direct Taxes rather than third-party summaries, and consult a qualified tax professional for your specific situation.
