What Is One Time Mandate (OTM) in SIP?

To maintain an SIP over the long term, installments must be deposited on time every month. In this context, the ‘One-Time Mandate’ (OTM) offers a convenient way to simplify SIP payments. In this blog, we will explore what OTM is, how it works with SIPs, how to set it up, and the key points to keep in mind while using it.

What is One Time Mandate (OTM) in SIP? 

A One Time Mandate (OTM) for an SIP is a payment authorization where an investor grants permission to debit SIP installments from their bank account based on pre-set terms. Once set up, there is no need to provide a separate cheque or payment instruction for each installment. OTMs are typically used for recurring SIP payments via the NACH (National Automated Clearing House) facility.

Why is it called a “One Time” Mandate?

Because the mandate does not need to be registered repeatedly. Once the OTM is successfully registered, SIP installments can be debited within the specified validity period and limit. However, the OTM itself is not an investment; it is simply an authorization granted for SIP payments.

Example: Suppose you start a monthly SIP of ₹5,000 and register an OTM for it. Once the mandate becomes active, ₹5,000 can be debited from your registered bank account on the scheduled date every month. You will not need to make a separate payment each month.

How Does OTM Work for SIP? 

To understand how OTM works, let’s look at the process in simple terms. While the method may vary slightly across different AMCs or platforms, the general workflow remains largely the same:

Step 1: Select SIP details

First, the mutual fund scheme, SIP amount, frequency, and debit date are determined. These details are subsequently used for the SIP instruction.

Step 2: Register the OTM

Next, an OTM/NACH mandate is registered against your bank account for SIP payments. This involves providing the necessary details regarding the bank account and the mandate.

Step 3: Mandate verification

The bank and the relevant payment system verify the mandate details. The OTM can only be used once the registration is successfully completed. Activation for a physical OTM may take time; some AMCs indicate a timeframe of approximately 25–30 calendar days in their documentation.

Step 4: SIP due date arrives

Once the mandate is active, the fund house or authorized entity sends a debit request based on the registered mandate on your scheduled SIP date. NACH is used for recurring and periodic payments, including mutual fund investments.

Step 5: Amount debited from the bank account

If the mandate conditions are met and there is sufficient balance in the account, the SIP amount is debited from the bank account. Subsequently, the SIP investment proceeds according to the standard transaction process.

OTM vs e-Mandate vs UPI AutoPay: What is the Difference? 

All three aim to simplify recurring payments, though their operational methods may differ. OTM/NACH is a mandate used for mutual fund SIP payments, whereas e-Mandate can be considered its digital counterpart. UPI AutoPay enables recurring payments via UPI and, according to the NPCI, can also be used for mutual fund payments.

Base	OTM / NACH	e-Mandate / eNACH	UPI AutoPay
Main Objective	Authorization for bank debits for recurring payments like SIPs.	Creating a recurring debit mandate digitally	Authorizing recurring payments via UPI
Payment system	Through NACH	Electronic mandate process	UPI
Used in SIP	Yes	Yes, wherever the AMC/platform supports it.	Yes, where available
Setup procedure	Depends on the physical or available digital process.	Generally, an online/electronic process.	Through a UPI-enabled app
Manual payment every month	Generally not needed.	Generally not needed.	Generally not needed.
Can the amount be debited from the account?	Yes, in accordance with the registered mandate.	Yes, in accordance with the authorized mandate.	Yes, in accordance with the approved AutoPay instruction.

Why is OTM Used for SIP? 

The primary objective of OTM is to simplify the payment of regular SIP installments, enabling the designated amount to be automatically debited in accordance with the active mandate.

• Eliminates the need for separate monthly payments: Once the OTM is active, there is no need to manually make payments for SIP installments every month. This streamlines the regular investment process.
• Reduces the risk of missing SIP installments: Investors might sometimes forget to make SIP payments due to busy schedules. The auto-debit facility helps mitigate this issue.
• Facilitates long-term SIP investments: If you wish to continue your SIP over several years, recurring debits can be executed via a registered mandate instead of repeating the payment process each month. NACH is used for such recurring and periodic transactions.
• Offers convenience in the payment process: Once the mandate is successfully activated, the investor generally does not need to provide separate payment instructions for each SIP installment. However, it is essential to maintain a sufficient balance in the bank account for the SIP debit to go through.

Example How OTM Works With a Monthly SIP 

Suppose Neha starts a monthly SIP of ₹5,000 and registers an OTM with a mandate limit of ₹10,000 for payments. Once the mandate is active, a debit request for ₹5,000 can be initiated on the scheduled SIP date. Here, the mandate limit is ₹10,000, while the actual SIP installment is ₹5,000 the two are not the same.

Information	Example
SIP amount	₹5,000 per month
Mandate limit	₹10,000
SIP frequency	Monthly
Payment method	OTM/NACH
Debit account	Registered bank account
Manual payment every month	Not required if the mandate is active.

How to register OTM for SIP?

Registering for an OTM is not difficult. You simply need to provide the correct details of the bank account from which the SIP installment will be deducted and approve the mandate. The process generally proceeds as follows:

• Select Your Bank Account: First, choose the bank account you wish to use for your SIP installments. It is crucial that the account details are accurate, as future debits will be made from this specific account.
• Set the Mandate Amount: An OTM involves specifying a debit amount or a maximum limit. For instance, if your SIP is for ₹5,000, you can set a higher limit in the mandate, provided the platform’s terms allow it.
• Approve the Mandate: Next, you must authorize the mandate using the prescribed method. This can be done via a physical form or a digital process; the available method depends on your AMC or investment platform.
• Check Registration Status: After submitting the mandate, you must wait for it to become active. Do not assume that the SIP payment will happen automatically before the OTM is active. It is advisable to check the status of both the mandate and the SIP before the first installment is due.
• Maintain Sufficient Balance Before the First Installment: Even after the mandate becomes active, it remains your responsibility to maintain a sufficient balance in your bank account to cover the SIP amount. If the balance is insufficient, the debit may fail, and applicable charges may be levied.

What Happens if There is Not Enough Money in the Bank? 

If there is insufficient balance in your account on the SIP due date, the debit via OTM (One Time Mandate) may fail. Consequently, that specific SIP instalment will not be processed. Depending on the bank’s or platform’s policy, charges may also be levied for a failed transaction. Therefore, it is advisable to maintain the required balance in your account beforehand.

Does the entire SIP get cancelled?

No, the failure of a single instalment does not mean that your entire SIP or the mutual fund units you have already purchased are automatically cancelled. However, if instalments fail repeatedly, the specific terms and conditions of the AMC or the platform may apply.

Is a failed SIP retried?

This varies across platforms. Some platforms do not retry failed payments, so one should not assume that the money will be debited again automatically. Be sure to check the policy of your AMC or investment platform.

Can You Cancel or Change an OTM?

Yes, an OTM (One Time Mandate) can be cancelled or modified if needed. However, stopping an SIP and cancelling an OTM are not the same thing. Stopping an SIP halts the investment instruction, whereas the mandate remains linked to the bank’s permission for recurring debits.

When might you need to cancel an OTM?

It may be advisable to cancel the OTM if you have stopped the SIP, changed your bank account, or no longer require the old mandate, especially if other SIPs are also linked to that same mandate.

How can an OTM be modified?

To change mandate details, you usually need to submit a new or modified mandate. The specific details that can be changed and the procedure involved depend on the rules of the respective bank, AMC, or investment platform.

What should you check before cancelling an OTM?

Before cancelling, verify which SIPs are linked to that mandate. If multiple SIPs rely on the same mandate, cancelling it could affect them as well. Therefore, if necessary, arrange an alternative valid payment method or mandate for the affected SIPs beforehand.
