How to modify a PPFAS SIP

From WebNotes, a public knowledge base. Last updated 17 May 2026. Reading time ~7 min. Level: Beginner.

Key facts

Modifiable parameters	Amount, SIP date, frequency, tenure/end-date, step-up rule, bank account, plan, option
Effective date	Next SIP date after a 7 to 10 business day processing buffer
Mandate-ceiling check	If the new SIP amount exceeds the existing mandate ceiling, a fresh mandate must be registered
Reversibility	A modification can itself be modified or reverted at any time

This guide covers modifying an active Systematic Investment Plan (SIP) on any PPFAS Mutual Fund scheme through the PPFAS SelfInvest portal at selfinvest.ppfas.com. Modification differs from pausing (which suppresses installments temporarily) and from cancelling (which terminates the SIP permanently). Modification adjusts the SIP’s parameters while keeping it active. Common modification reasons include income changes, goal recalibration, SIP-date alignment with cash inflows, or adding a step-up rule.

Prerequisites

An active PPFAS SIP under SelfInvest.
The modification request must be placed at least 7 to 10 business days before the next scheduled SIP date. The next installment may still process under the prior parameters if the request is too close.
For amount increases above the existing mandate ceiling: an active second-mandate-registration session, since SelfInvest will prompt for fresh NACH e-mandate or UPI Autopay setup at the higher ceiling.
For SIP-date changes: the new date must be one of the supported SIP dates for the scheme (typically 1, 5, 7, 10, 14, 17, 21, 25, 28 for monthly SIPs).
For frequency changes: the new frequency must be supported by the scheme. Monthly and quarterly are universally supported; daily, weekly, and fortnightly vary by scheme.
For tenure changes: extending the end-date past the original requires a mandate that is valid through the new end-date.

Step-by-step procedure

Step 1: Log in to selfinvest.ppfas.com

Open selfinvest.ppfas.com or the SelfInvest mobile app. Log in with PAN, password, and OTP, or biometric authentication.

Step 2: Navigate to Service Requests then SIP Management

From the dashboard, tap Service Requests then SIP Management. SelfInvest lists all active SIPs with their scheme, amount, frequency, and SIP date.

Step 3: Select the SIP to modify

Tap the SIP. SelfInvest displays the SIP detail screen with available actions:

Pause SIP.
Modify SIP.
Cancel SIP.
Resume SIP (if paused).

Choose Modify SIP.

Step 4: Choose the parameters to change

SelfInvest’s modification screen presents each modifiable parameter with the current value and an edit field. Modifiable parameters:

Per-installment amount: Increase or decrease the SIP amount.
SIP date: Change to a different supported date.
Frequency: Switch between monthly, quarterly (or other supported cadences).
Tenure: Change from perpetual to fixed end-date, change the end-date, or change from fixed to perpetual.
Step-up rule: Add, modify, or remove the SIP top-up rule.
Bank account: Switch to a different registered bank account.
Plan and option: Switch between Growth and IDCW (rarely used mid-SIP).

Select one or multiple parameters to change in the same modification request.

Step 5: Enter the new values

For each parameter:

New amount: Enter the new per-installment amount. Minimum Rs 1,000 for PPFCF (and other PPFAS equity schemes); Rs 500 for ELSS; refer to PPFAS minimum investments per scheme for scheme-specific minimums.
New SIP date: Pick from the available dates dropdown.
New frequency: Pick from the supported frequencies dropdown.
New tenure: Pick perpetual or enter a new end-date.
New step-up rule: Specify escalation mode (percentage or fixed-amount), increment, frequency (annual or half-yearly), and cap.
New bank account: Pick from registered bank accounts under the PAN (if multiple are linked); otherwise update through a separate Service Request first.

If the new SIP amount exceeds the existing mandate ceiling, SelfInvest displays a prompt to register a fresh mandate at the higher ceiling. Complete the mandate-registration flow inline (see how to start a PPFCF SIP via SelfInvest portal for the mandate-registration mechanics).

Step 6: Review the modification preview

SelfInvest’s preview screen shows:

Parameters changed: A side-by-side view of old and new values.
Effective date: The next SIP date on which the modified parameters take effect, typically 7 to 10 business days after submission.
Expected next-installment amount: The amount that will debit on the effective date.
Mandate-ceiling action needed (if any): A flag for fresh mandate registration.

Verify the preview. Any visible error (wrong date, wrong amount, mandate-ceiling mismatch) must be corrected at this step.

Step 7: Authorise the modification

Authorise with:

Aadhaar OTP (sent to the Aadhaar-registered mobile).
SelfInvest password and OTP.
Biometric authentication on the mobile app.

SelfInvest issues a modification request reference number and the effective date.

Step 8: Verify and track the post-modification SIP

After the effective date, SelfInvest’s dashboard reflects the modified SIP. The next installment debits the modified amount on the modified SIP date with the modified frequency. The first post-modification installment is the operational confirmation that the change has taken effect.

SelfInvest sends a confirmation email at submission and another after the first post-modification installment completes.

What can go wrong

Modification too close to next SIP date: The next installment may still process under the prior parameters. Allow 7 to 10 business days between modification submission and the desired effective date.
Amount increase above mandate ceiling: The mandate must be re-registered at the higher ceiling. If the bank’s e-mandate processing has a backlog, the new mandate may not activate in time, and the first post-modification installment may fail. Plan with margin.
Frequency change between monthly and quarterly: Switching from monthly to quarterly typically does not require a new mandate (the same mandate ceiling supports lower-frequency higher-amount debits if the per-debit value is within the ceiling). But check the mandate’s per-debit cap against the new quarterly amount.
ELSS amount reduction: Reducing the ELSS SIP mid-FY reduces the 80C contribution. To maintain the FY target, supplement with a one-time lump-sum order in ELSS before 31 March.
Step-up rule conflict: Adding a step-up rule to a SIP with a mandate ceiling close to the current installment can cause the step-up to fail at the first escalation. Set the mandate ceiling at 2x to 3x the starting SIP amount when adding a step-up.
Tenure extension past mandate validity: If the existing NACH mandate expires before the new SIP end-date, register a fresh mandate or accept that the SIP will fail when the mandate expires.
SIP date change to a non-supported date: The new SIP date must be one of the supported dates for the scheme. Unsupported dates are not accepted by the modification screen.
Multiple parameter changes in a single submission: Combining many parameter changes in one submission can increase the risk of operational misalignment. For complex modifications (amount, date, frequency, step-up all together), consider doing them as separate sequential modifications to verify each takes effect cleanly.
Modification on a paused SIP: A modification submitted during a pause typically applies from the pause-resumption date, not immediately. Verify the effective date in the preview.
Bank account change with pending SIP debit: If the bank account is being modified and a SIP debit is imminent, the SIP debit may go to the old account or fail. SEBI requires a 7-day cooling-off period after bank-account changes; plan the modification timing accordingly.

Common modifications

Reason	Parameter to modify	Notes
Income increase	Amount (increase)	Mandate-ceiling check; consider adding step-up rule
Income decrease	Amount (decrease)	No mandate impact; new amount takes effect from next SIP date
Salary credit date changed	SIP date	Pick a supported date close to but after the new salary credit
Switch to less frequent contribution	Frequency (monthly to quarterly)	Per-debit value usually within existing mandate ceiling
Add gradual annual escalation	Step-up rule	Mandate ceiling sized for projected maximum
Move from indefinite to goal-aligned horizon	Tenure (perpetual to fixed end-date)	No operational impact other than the new end-date
Switch primary bank	Bank account	7-day cooling-off applies; plan timing
Switch from Growth to IDCW	Option (rare)	Usually better to leave existing SIP in Growth and start fresh IDCW SIP
