Advance Tax on PMS Investments: Due Dates, Interest and What to Pay

In a Portfolio Management Service, capital gains are realised every time your portfolio manager buys or sells a holding on your behalf. Unlike a salary payment or a bank deposit, these gains carry no tax deducted at source for resident investors. The job of estimating what you owe and paying it through the year, rather than waiting for the annual return, sits entirely with you.

Getting it wrong carries a cost. This guide walks through the advance tax due dates that apply to PMS investors, how Portfolio Management Services gains are actually taxed, the interest that applies on shortfalls, a relief provision written specifically for capital gains, and a practical method to estimate what is due each quarter. The rates and dates below are current for FY 2025-26.

What advance tax is, in brief

Advance tax is income tax paid during the year the income is earned, in instalments, rather than as one payment after the financial year closes. It works on a pay-as-you-earn basis, and the governing provisions sit in the Income Tax Act.

It applies whenever your total tax liability for the year, after accounting for TDS already deducted, is expected to exceed ₹10,000. There is one notable carve-out: resident senior citizens aged 60 or above who have no income from business or profession are exempt from paying advance tax.

Advance tax does not add to your annual liability. It simply collects the same amount you would owe on your return, spread across the year instead of paid in one sum at the end.

Why advance tax is harder for PMS investors than for most taxpayers

A Portfolio Management Service holds securities directly in the investor’s own name, so for tax purposes the PMS account is treated as a pass-through. This differs from a mutual fund, which is itself a pass-through vehicle that is not taxed at the fund level. In a PMS, every trade the manager executes happens directly in the client’s account, so each transaction is the investor’s own taxable event rather than the fund’s.

The practical effect is that the portfolio manager, not the investor, decides when a gain is booked. You may not control the timing or the size of the taxable event that results.

Add to this the absence of TDS on resident capital gains. Nothing is withheld at source, so nothing reduces the estimate you need to make. Investors with capital gains outside the TDS net have to monitor transactions through the year and estimate the additional liability themselves.

It also helps to know that SEBI-registered PMS structures come in two forms: direct-equity PMS, where individual shares sit in the investor’s own demat account, and PMS built on underlying mutual fund units. The structure you hold decides how each gain is computed, so confirm which one applies to your portfolio before you apply any rate below.

How PMS gains are taxed

The first question is classification: are your PMS gains capital gains, or business income? Most PMS investors report capital gains, since the portfolio manager trades on their behalf with a longer-term investment intent. A very high frequency of trading, however, can push the classification towards business income, which changes both the applicable rates and what expenses may be deducted. Keep your classification method consistent from year to year, and for larger portfolios take a professional opinion rather than assuming.

For equity holdings, long-term capital gains, where the holding period exceeds 12 months, are taxed at 12.5% above an annual exemption of ₹1.25 lakh. Short-term capital gains are taxed at 20%. These rates have applied from 23 July 2024 onward.

For non-equity holdings, the treatment turns on the specific instrument, and the rules diverge sharply after recent amendments:

• Listed bonds and debentures: gains on holdings of 12 months or less are taxed at your slab rate; on holdings beyond 12 months, at 12.5% without indexation.
• Debt mutual fund units acquired on or after 1 April 2023: taxed at your slab rate regardless of the holding period, under Section 50AA. There is no long-term concession and no indexation benefit. Units bought before that date follow the older holding-period rules.
• Unlisted bonds and debentures transferred, redeemed or maturing on or after 23 July 2024: deemed short-term and taxed at your slab rate, whatever the holding period.

Confirm the treatment for each holding rather than assuming one rate applies across the debt sleeve.

Dividends received within the PMS portfolio are taxable at the investor’s slab rate, with TDS deducted at 10% once payments cross the prescribed threshold.

The common thread is that holding period and asset type drive the tax outcome. Two portfolios with identical rupee profit can end up with very different tax bills depending on what was held, and for how long.

Advance tax due dates and instalments

Advance tax is paid in four instalments through the financial year:

• 15% of the total liability by 15 June
• 45% cumulative by 15 September
• 75% cumulative by 15 December
• 100% by 15 March

A small grace is built in: no interest is charged on the first two instalments if you have paid at least 12% of the total by 15 June and at least 36% by 15 September. Any tax paid up to 31 March also counts as advance tax for that year.

One point keeps the guidance useful regardless of the year you are reading it. From FY 2026-27 onward, advance tax is governed by the Income-tax Act, 2025, with the core provisions under Sections 403 to 408 and interest under Sections 424 and 425. FY 2025-26 remains under the Income-tax Act, 1961, where the same provisions sit under the more familiar Sections 234B and 234C. When searching for guidance online, look up both sets of section numbers, since much existing material still refers to the old numbering.

The capital gains relief most PMS investors miss

The law does not expect anyone to estimate a gain that has not yet been booked. This is a genuine relief for PMS investors, where the manager’s trading calls decide when a gain crystallises. Advance tax on a capital gain is required only in the instalment that falls after the gain actually arises.

For example, if your portfolio manager books a large gain through a sale in February, the tax on that gain is payable with the 15 March instalment. It cannot retroactively be treated as a default on the June, September or December instalments, because the gain did not exist at those earlier dates.

The relief has limits. If you pay the tax on the capital gain within the correct instalment window, interest for the earlier instalments generally does not apply to that specific gain. That protection is narrow. It removes only the deferment interest tied to the timing of that gain. It does not remove the separate shortfall interest that applies if your total advance tax paid for the year, across all instalments, still falls short of 90% of your final assessed tax.

The practical takeaway is to track realised gains every quarter, so each gain is captured in the correct instalment rather than left to surface at filing time.

What it costs to get it wrong

Two separate interest charges can apply to advance tax shortfalls, and they can run concurrently, each at 1% per month:

• Shortfall interest (Section 234B under the 1961 Act, Section 424 under the 2025 Act): applies when the total advance tax paid during the year is less than 90% of your final assessed tax.
• Deferment interest (Section 234C under the 1961 Act, Section 425 under the 2025 Act): applies when any individual instalment falls short of its required cumulative percentage, regardless of whether the year-end total eventually catches up.

A worked example makes the stacking clear. Say your manager books a short-term equity gain of ₹40 lakh in November. At 20%, the tax on it is ₹8 lakh. Assume you pay nothing toward it during the year and clear it only when filing your return the following July.

• Deferment interest (234C): because the gain arose in November, the June and September instalments are protected by the relief above and carry no interest. The 15 December instalment (75% cumulative) is short by ₹6 lakh, drawing 1% per month for three months, or ₹18,000. The 15 March instalment (100%) is short by ₹8 lakh, drawing 1% for one month, or ₹8,000. Subtotal: ₹26,000.
• Shortfall interest (234B): advance tax paid was nil, below the 90% threshold, so interest runs at 1% per month from 1 April until you pay. Cleared in July, that is four months on ₹8 lakh, or ₹32,000.

Total interest: ₹58,000 on an ₹8 lakh liability, and it climbs the longer payment is delayed. The two charges sit on their own timelines and compound the delay independently.

How to estimate what you owe, quarter by quarter

• Request an interim realised capital gains statement from your PMS provider ahead of each due date, and especially before 15 March, since this instalment often carries the year’s largest gains.
• Ask for the data in an itemised, spreadsheet-friendly format, with short-term and long-term gains clearly separated, so reconciliation and filing are easier.
• Add the PMS gains to every other source of income for the year: salary, rental income, interest, dividends, and any capital gains from outside the PMS.
• Reconcile your working numbers against your Annual Information Statement (AIS) and Taxpayer Information Summary (TIS). A mismatch between what the PMS reports, what the AIS shows, and what you file can trigger a scrutiny notice.
• Treat the advance tax figure calculated by your PMS provider as one input, not the final number. It accounts only for that one portfolio. Your other income still has to be layered in and the total reassessed before you pay.

Levers to manage the liability

Set off capital losses. Short-term capital losses can be set off against both short-term and long-term gains. Long-term capital losses can be set off only against long-term gains. Any unused losses can be carried forward for eight assessment years, provided the return is filed on time.

Tax-loss harvesting. Booking losses before 31 March reduces net taxable gains for the year. India has no wash-sale rule, so the same security can be repurchased immediately after the loss is booked, keeping your market exposure intact while the taxable gain is reduced. This should fit your investment view first, with the tax benefit as a secondary consideration.

Fee deductibility. This area is genuinely unsettled. If your PMS income is classified as capital gains, portfolio management fees are generally not an admissible deduction. If it is classified as business income, they typically are. Given how much rides on classification, treat this as a question for a qualified tax adviser rather than something to assume either way.

A note for NRI PMS investors

The picture changes for non-resident investors. Unlike residents, NRIs face TDS on PMS gains, which alters the advance tax calculation, though a balance can still be payable depending on the applicable rate and any treaty relief.

Repatriation of proceeds depends on the account structure used under FEMA. Investments routed through an NRE account are fully repatriable, while those routed through an NRO account carry restricted repatriation, generally capped at USD 1 million per financial year subject to compliance and documentation.

A pre-deadline checklist

Run through this before each instalment date:

• Pull the latest realised gains statement from your PMS provider
• Separate short-term and long-term gains
• Add all non-PMS income for the year
• Apply any eligible capital loss set-offs
• Reconcile the numbers against your AIS
• Compute the cumulative percentage of tax due as of that date
• Pay before the deadline

The 15 March instalment usually carries the final and often the largest catch-up payment, particularly in years where the manager booked significant gains late in the financial year. Give it extra attention.

How to pay

Advance tax can be paid through the income tax e-filing portal or at an authorised bank, using Challan 280 under the advance tax head. Keep the challan receipt safely, since it is needed for reconciliation when you file your return.

Conclusion

Advance tax on a PMS portfolio works best as a quarterly habit tied to your realised gains, rather than a scramble in March or at filing time. The feature that makes a PMS distinct, securities held directly in the investor’s own name, is the same feature that places the estimation and payment responsibility on the investor rather than on a fund. A simple quarterly routine built around your PMS statements, your other income, and the AIS keeps both categories of interest at bay and avoids surprises when the return is finally filed.

FAQs

Does a PMS provider deduct TDS on my capital gains?
 No, not for resident investors. Capital gains from a PMS are not subject to TDS the way salary or certain other payments are, which is precisely why the responsibility for advance tax estimation falls on the investor.

What happens if I only realise a large gain in the last quarter of the year?
 You are required to pay advance tax on that gain only in the instalment falling after it was realised, typically the 15 March instalment. You are not penalised for failing to anticipate it earlier, provided you pay it within that window and your overall year-end payment still meets the 90% threshold.

Are PMS management fees tax deductible?
 This depends on how your PMS income is classified. If it is treated as capital gains, fees are generally not deductible. If it is treated as business income, they usually are. This is a contested area, so confirm it with a tax professional based on your specific portfolio.

How is a PMS different from a mutual fund for tax purposes?
 A mutual fund is a pass-through vehicle that is not taxed at the fund level. A PMS holds securities directly in the investor’s own name, so every transaction the manager makes is the investor’s own taxable event in real time, rather than being pooled and distributed later.

Do NRIs investing through PMS have the same advance tax obligations?
 Not exactly. NRIs are subject to TDS on PMS gains, which changes how much advance tax, if any, remains payable. Repatriation of the proceeds also depends on whether the investment was routed through an NRE or NRO account under FEMA rules.

Which law governs advance tax right now, the 1961 Act or the 2025 Act?
 It depends on the financial year. FY 2025-26 remains under the Income-tax Act, 1961, with Sections 234B and 234C. From FY 2026-27, the Income-tax Act, 2025 applies, with the equivalent provisions under Sections 403 to 408 for the liability and Sections 424 and 425 for interest.
