OTM in Mutual Funds: Meaning, Setup & Advantages

The one time Mandate (OTM) is a digital facility that allows investors to automate mutual fund transactions like SIP. Once registered it ensures convenience, discipline and security by eliminating repetitive approvals.

OTM is backed by NACH (National Automated Clearing House) an RBI regulated system that enables automatic debits from your bank account. To activate NACH you simply fill out and submit a mandate form with your bank. Once verified your payments are debited as per your chosen schedule.

• It can be registered online (e-mandate) or offline (physical form)
• A single OTM can be used for multiple SIPs and transactions within the set limit.

• OTM promotes discipline, convenience and consistency, key ingredients for long term wealth creation

What is OTM (One-Time Mandate)?

A One Time Mandate (OTM) in mutual funds is a one-time authorization that allows an investor’s bank to automatically debit a pre defined amount for mutual fund investments such as SIPs. Once registered the mandate ensures that transactions are processed seamlessly without the need for repeated approvals making investing more convenient and disciplined.

By registering OTM for SIP once either online using e-mandates and net banking authentication or offline by submitting a mandate form investors can link multiple SIPs or purchases under the same authorization provided the combined amount remains within the chosen limit.

Importantly the maximum mandate amount is not the sum deducted every time it is only a cap giving investors control and flexibility. OTM mandates usually remain valid until the investor modifies or cancels them.

How OTM Works?

Setting up a One Time Mandate means giving your bank permission to automatically transfer money for your mutual fund investments whenever required. Once the mandate is active your SIP instalment or lump sum request is directly debited from your bank account, as long as it is within the limit you have specified.

After the money is deducted, the mutual fund house receives it and allots units based on the Net Asset Value (NAV) determined by SEBI’s cut off timings.

For example, if your SIP is due on the 10th and the debit happens before the cut-off time, you get units at the same day’s NAV, whereas delays are allotted the next business day’s NAV. This simple and automated process ensures your investments are carried out smoothly and on time, freeing you from the stress of remembering dates or making manual payments every month.

How Can an Investor Register for OTM?

Investors can register for a One Time Mandate either online or offline depending on their convenience. The online process is simple and usually done through the mutual fund house’s website or the registrar and transfer agent (RTA) portal where authentication is completed using net banking or an electronic signature. For those who prefer traditional methods OTM can also be registered offline by submitting a physical mandate form at the mutual fund branch or through a distributor. Most fund houses including Kotak Mutual Fund provide an easy e-mandate facility that makes the process quick, secure, and completely paperless ensuring that investors can set up their mandate without hassle.

Advantages of OTM in Mutual Fund

1. Convenience in Investing

• Once an OTM is registered, SIP instalments are debited automatically on the scheduled date.

2. Consistency in Payments

• Automatic deductions ensure that no SIP instalment is skipped.
• This helps investors stay regular with contributions and avoid breaks in their investment plan.

3. Time Saving Process

• Registering a one-time mandate removes the need for repetitive approvals or paperwork every month.

4. Flexibility Across Schemes

• A single OTM can be used for multiple SIPs across different mutual fund schemes.
• Investors don’t have to set up a new mandate each time they start another SIP.

5. Encourages Financial Discipline

• Since contributions are automated, it becomes easier to stick to a long term investment plan.

6. Safe and Regulated Mechanism

• OTM operates through the National Automated Clearing House (NACH), which is regulated and secure.
• Transactions go through proper authentication, reducing chances of fraud.

7. Control Over Limits

• At the time of OTM registration investors decide the maximum debit limit.
• This ensures security while also giving flexibility to manage multiple SIPs under one mandate.

Mandate Amount, Validity & Limits

When you register for a One Time Mandate (OTM) you can choose a maximum limit based on your comfort level. For example, Rs.1 lakh or even more. This limit only sets the upper cap for debits and does not mean that the same amount will be deducted every time. The actual deduction will depend on the SIP or lump sum transaction you place within that cap. An OTM remains valid until you decide to cancel it with your bank or the mutual fund which means you don’t have to renew it frequently. This flexibility ensures that while your investments run smoothly, you still stay in control of how much can be debited from your account.

Transactions You Can Do via OTM

Once you set up a one Time Mandate (OTM) you can use it for different types of mutual fund transactions without needing to authorize every payment separately. The most common use is for Systematic Investment Plans (SIPs), where the amount is automatically deducted on your chosen date. You can also make lump sum investments using the same mandate which saves you from registering again for each transaction. Additionally, OTMs can be used for placing additional purchase requests in existing schemes.

Applicable NAV & SEBI Cut Offs with OTM

In mutual fund investments, SEBI has made it clear that the applicable NAV depends on when the money is actually debited from your bank and credited to the AMC’s account.

• Before 3:00 PM (Equity & Debt Funds other than liquid/overnight): If the debit is successful and the funds are available in the AMC’s account before 3:00 PM on a business day, the same day’s NAV is applied.
• After 3:00 PM: If the debit or credit takes place after 3:00 PM, or if funds are available in the AMC’s account post cut-off, the next business day’s closing NAV[PP(K1] [MOU2]  will be applicable.
• Liquid & Overnight Funds: For these categories the cut off time is 1:30 PM.

How to Modify, Increase or Cancel an OTM?

• Modify / Increase Limit - Investors can request an enhancement in their OTM limit if their SIP amount or overall investment plan requires a higher cap. The revised mandate will need to be authenticated through the bank.
• Cancel OTM - If you wish to stop using OTM for future transactions, you can submit a cancellation request either online through the AMC/RTA portal or offline via a physical form. Once processed no further debits will be made.
• Bank Account Change - In case you shift your primary bank account a fresh OTM mandate must be registered with the new bank details as mandates are account specific.

Investor Checklist Before Enabling One Time Mandate

• Confirm Bank Compatibility - Check with your bank or AMC/RTA if your account supports OTM before applying.
• Set a Suitable Limit - Choose an OTM limit that is comfortably higher than your current SIP or lump sum requirement (for example, if your SIP is Rs 10,000 you may set Rs 50,000). This ensures future increases or additional transactions don’t require a fresh mandate.
• Keep Mobile & Email Updated - Your registered mobile number and email ID must be active as banks and AMCs send OTPs, debit alerts and confirmation messages through these channels.
• Track with UMRN - Every OTM is assigned a Unique Mandate Reference Number (UMRN). Note it down carefully as it helps you track, modify or cancel your mandate when needed.
• Check Validity Period - Most OTM validity remain valid until you cancel them but confirm with your bank if there are specific validity conditions.

Conclusion

The One Time Mandate (OTM) is a simple yet powerful facility that streamlines mutual fund investing by automating payments for SIPs, lump sum purchases and other transactions. By setting it up once investors can enjoy hassle free, timely and disciplined investing without worrying about missing due dates or repetitive approvals. Since OTM works through the secure NACH system and follows SEBI’s cut off rules for NAV allotment it ensures both safety and transparency. With flexibility to use one mandate across multiple schemes and complete control over limits, OTM makes the investment journey smoother and more efficient for investors of all profiles.
