Investing in mutual funds has become increasingly popular in India, and for good reason. They offer a simple way to grow your money over time. One of the easiest methods to invest in mutual funds is through a Systematic Investment Plan (SIP). However, remembering to make regular payments can be a hassle. That's where One Time Mandate (OTM) comes in handy.

How Does OTM Work?

Let's break down how OTM works with a simple example. Imagine you want to invest ₹2,000 every month in a mutual fund through an SIP. Here's how OTM would make this process smooth:

  • Setting up: You set up an OTM with your bank, telling it to transfer ₹2,000 to your chosen mutual fund on the 5th of every month.
  • Automatic transfers: Once set up, your bank will automatically debit ₹2,000 from your account on the 5th of each month.
  • Investment: This money is then credited to your mutual fund account, purchasing units of the scheme at that day's price.
  • Repeat: This process repeats each month without you having to do anything.

The key thing to remember is that you need to have enough money in your account on the transfer date. If your account doesn't have sufficient funds, the transfer won't happen, and you might miss that month's investment.

Key Features Of OTM

OTM comes with several features that make it a popular choice among mutual fund investors:

  • One-time setup: As the name suggests, you only need to set it up once, and it continues to work for the specified duration.
  • Flexibility: You can set the amount, frequency (monthly, quarterly, etc.), and mandate duration according to your preference.
  • Upper limit: You can set a maximum limit for the mandate, ensuring that no amount higher than what you've authorized is debited.
  • Multiple fund houses: One OTM can be used for investments across different mutual fund companies, saving you the hassle of setting up separate mandates.
  • Easy modification: If your financial situation changes, you can easily modify or cancel the OTM.

These features make OTM a versatile tool that adapts to your investment needs while keeping the process simple and automated.

Advantages of OTM in Mutual Funds

A One Time Mandate (OTM) simplifies mutual fund investing by automating payments and reducing manual effort. Some of its key advantages include:

  • Automates SIP Payments: Your SIP instalments are debited automatically on the scheduled date.
  • Saves Time and Effort: Eliminates the need to manually authorise every mutual fund transaction.
  • Prevents Missed Investments: Ensures investments continue even if you forget the due date.
  • Supports Investment Discipline: Regular investments help maintain consistency in your financial plan.
  • Single Registration: OTM needs to be registered only once for future eligible transactions.
  • Secure Payment Process: Transactions are processed through an authorised bank mandate.
  • Flexible Investment Limit: You can set a maximum debit limit while registering the mandate.
  • Convenient for Multiple Transactions: The same OTM can be used for various mutual fund transactions within the approved limit.

Step 1: Choose the OTM Option

After understanding what is OTM the article further explains the transactions covered under OTM. 
 

Transactions Covered Under OTM

A One Time Mandate (OTM) can be used for several mutual fund transactions, making investments more convenient.

Transaction Explanation
Systematic Investment Plan (SIP) Automatically debits the SIP instalment on the scheduled investment date.
Additional Purchases Enables one-time additional investments without entering bank details each time.
Lumpsum Investments Allows eligible lump sum investments to be processed through the registered mandate.

Systematic Withdrawal Plan (SWP) May support certain bank-related debit instructions, depending on the platform and AMC requirements.
Multiple Mutual Fund Schemes The same OTM can be used across eligible schemes offered on the investment platform, subject to the approved mandate limit.

Mandate Amount, Validity & Limits

When registering OTM in mutual funds, investors must specify the maximum amount that can be debited from their bank account. This amount acts as the upper limit for all eligible transactions processed under the mandate.

  • Mandate Amount: You can choose a maximum debit amount based on your investment requirements and future financial plans.
  • Validity Period: The mandate remains valid for the period selected during registration or until it is cancelled.
  • Applicable Limits: Every transaction processed through the OTM must remain within the approved mandate limit. If the transaction amount exceeds the registered limit, a new or revised mandate may be required.
  • Bank and AMC Guidelines: The minimum and maximum mandate limits may vary depending on the bank, Asset Management Company (AMC), or investment platform.

How to Modify or Cancel an OTM?

If your investment requirements change, you can update or cancel your OTM in mutual funds through your mutual fund platform or registrar.

Modify an Existing OTM

  • Log in to your investment account.
  • Navigate to the OTM or bank mandate section.
  • Update the mandate amount, validity period, or bank details, if permitted.
  • Complete the required authentication process for the changes to take effect.


Increase the Mandate Limit

  • Submit a request to revise the existing mandate limit.
  • Your bank may require fresh authentication before approving the revised limit.

Cancel an OTM

 

  • Visit the OTM management section on your investment platform.
  • Select the existing mandate and submit a cancellation request.
  • Once processed, future automatic debits under the mandate will stop. However, existing SIP registrations linked to the mandate may need to be updated or cancelled separately.
     

How to Use OTM for SIP Investments

OTM in SIP simplifies the investment process by automating the payment of your SIP instalments. Instead of authorising every transaction manually, a registered One Time Mandate allows your bank to debit the SIP amount automatically on the scheduled date.

To use OTM in SIP, follow these steps:

  • Register a One Time Mandate with your mutual fund platform or investment app.
  • Complete the bank verification and mandate approval process.
  • Start a new SIP or link the approved OTM to an existing SIP.
  • Ensure your SIP amount remains within the approved mandate limit.
  • Maintain sufficient funds in your bank account before each SIP due date so that the investment is processed successfully.

Using OTM for SIP investments helps ensure timely contributions and reduces the risk of missed instalments due to manual payment delays.
 

Things to Keep in Mind Before Setting Up an OTM

Before registering OTM in mutual funds, consider the following practical points:

  • Maintain Sufficient Bank Balance: Ensure adequate funds are available before the scheduled debit date to avoid transaction failures.
  • Choose an Appropriate Mandate Limit: Set a limit that accommodates your current SIPs as well as any future investments you may plan.
  • Check the Mandate Validity: Review the validity period and renew the mandate if it is nearing expiry.
  • Verify Bank Details Carefully: Enter the correct account number and IFSC to avoid registration issues.
  • Monitor Your Transactions: Regularly check your bank account and investment statements to confirm successful debits.
  • Review Existing SIPs: If you modify or cancel your OTM, ensure your linked SIPs continue without interruption by updating the payment instructions where required.
  • Understand the Terms and Conditions: Read the bank and mutual fund platform guidelines regarding mandate registration, modification, and cancellation before submitting your request.

Conclusion

A one-time mandate (OTM) is a powerful tool that simplifies investing in mutual funds. It brings convenience, discipline, and consistency to your investment journey. By automating your investments, OTM helps you stick to your financial plans and potentially benefit from long-term wealth creation. While it's a great tool, remember to review your investments regularly and ensure they align with your changing financial goals.
