Is a Medium Enterprise Also Protected Under the 45-Day Payment Rule?

Quick answer

Ordinarily, the special delayed-payment protections under Sections 15 to 19 of the Micro, Small and Medium Enterprises Development Act, 2006 (“MSMED Act”) are meant for Micro and Small Enterprises, not Medium Enterprises.

The statutory definition of “supplier” under Section 2(n) covers a qualifying micro or small enterprise. Therefore, an enterprise that is independently classified as Medium does not ordinarily receive:

The statutory maximum payment period of 45 days under Section 15;
Compound interest with monthly rests at three times the RBI bank rate under Section 16;
The recovery liability under Section 17;
Access to the Micro and Small Enterprises Facilitation Council under Section 18; or
The 75% pre-deposit protection under Section 19.

However, there is an important exception that is frequently missed.

Where an existing Micro or Small Enterprise is subsequently reclassified upward—for example, from Small to Medium—it may continue to avail the non-tax benefits of its previous category for three years from the date of upward change. The Government has expressly stated that these non-tax benefits include delayed-payment benefits.

Therefore, the statement “the moment a Small enterprise becomes Medium, it immediately loses all delayed-payment protection” is not entirely correct. The three-year transitional protection must be examined.

The buyer-side tax consequence under Section 43B(h) of the Income-tax Act, 1961 is different. That provision applies to amounts payable to qualifying Micro and Small Enterprises. The three-year notification concerns non-tax benefits and should not automatically be assumed to extend the tax disallowance to payments owed to an enterprise classified as Medium.

Why is there so much confusion?

The legislation is called the Micro, Small and Medium Enterprises Development Act. It is therefore natural to assume that every right under the Act applies equally to Micro, Small and Medium Enterprises.

That is not how the Act is structured.

Some provisions deal with development, classification, credit, procurement, competitiveness and promotional measures across the MSME sector. The delayed-payment chapter, however, is drafted specifically around the rights of a “supplier.”

Section 2(n) defines a supplier principally as a Micro or Small Enterprise that has filed the prescribed memorandum. Medium Enterprises are not included in the main part of that definition.

The statutory recovery framework is also administered through bodies called Micro and Small Enterprises Facilitation Councils, not Micro, Small and Medium Enterprises Facilitation Councils.

This distinction is deliberate in the statutory language, even if its commercial justification may be debated.

Which provisions create the 45-day protection?

The delayed-payment framework is found in Sections 15 to 19 of the MSMED Act.

Section 15: payment obligation

Where a supplier supplies goods or renders services to a buyer, payment must be made on or before the date agreed upon in writing.

However, the agreed period cannot exceed 45 days from the day of acceptance or deemed acceptance.

The 45-day period is a maximum ceiling where there is a written payment agreement. It is not necessarily the payment period in every case.

If there is no written agreement, payment is linked to the “appointed day,” which is broadly the day immediately following the expiry of 15 days from the date of acceptance or deemed acceptance.

Therefore:

No written agreement does not automatically mean that the buyer gets 45 days; and
A written agreement cannot ordinarily extend the period beyond 45 days for an eligible supplier.

Section 16: statutory interest

If the buyer fails to pay within the permissible period, the buyer becomes liable to pay compound interest with monthly rests at three times the bank rate notified by the Reserve Bank of India.

This statutory interest applies notwithstanding anything contrary in the contract or any other law.

Section 17: recovery of dues

The buyer is liable to pay the principal amount together with the statutory interest payable under Section 16.

Section 18: Facilitation Council proceedings

A reference regarding the amount due under Section 17 may be made to the MSEFC. The process begins with conciliation and, if conciliation fails, proceeds to statutory arbitration before the Council itself or a referred institution.

Section 19: protection of the award

A buyer seeking to set aside the resulting award is ordinarily required to deposit 75% of the awarded amount before its challenge can be entertained.

The official statutory text can be read in the MSMED Act, 2006 on India Code.

Why does an ordinary Medium Enterprise fall outside this framework?

The answer lies in the definition of “supplier.”

Sections 15 to 19 do not apply merely because a business can generally be described as an MSME. They apply where goods or services are supplied by a statutory “supplier.”

The main part of Section 2(n) defines a supplier as a Micro or Small Enterprise that has filed the prescribed memorandum. It also includes certain specifically mentioned corporations and bodies engaged in selling goods produced or services provided by Micro or Small Enterprises.

An independently established Medium Enterprise does not enter the definition merely because “Medium” appears in the title of the MSMED Act.

Accordingly, if a business was already a Medium Enterprise when it registered and supplied the relevant goods or services, and no transitional protection applies, it ordinarily cannot invoke Sections 15 to 19.

Its payment rights will then depend upon:

The payment terms in the contract;
The Sale of Goods Act, 1930;
The Indian Contract Act, 1872;
Contractual interest provisions;
The Interest Act, 1978;
The Code of Civil Procedure, 1908;
The Commercial Courts Act, 2015;
An applicable arbitration agreement;
The Negotiable Instruments Act, 1881; or
The Insolvency and Bankruptcy Code, 2016, where its conditions are satisfied.

What are the current MSME classification limits?

The classification limits were revised with effect from 1 April 2025.

The current composite criteria are:

Category	Investment in plant and machinery or equipment	Annual turnover
Micro Enterprise	Not more than ₹2.5 crore	Not more than ₹10 crore
Small Enterprise	Not more than ₹25 crore	Not more than ₹100 crore
Medium Enterprise	Not more than ₹125 crore	Not more than ₹500 crore

The revised classification is confirmed by the Ministry of MSME and its Annual Report 2025–26.

Both investment and turnover limits must be satisfied to remain within a category.

For example:

Investment of ₹20 crore and turnover of ₹90 crore: Small;
Investment of ₹20 crore and turnover of ₹120 crore: Medium;
Investment of ₹30 crore and turnover of ₹80 crore: Medium; and
Investment of ₹130 crore or turnover above ₹500 crore: Outside the current MSME classification.

Exceeding either the investment ceiling or the turnover ceiling can result in upward classification.

How are investment and turnover calculated?

Classification is not determined merely from figures selected by the business in an application.

Investment calculation

The value of investment in plant and machinery or equipment is generally linked to the income-tax return filed under the Income-tax Act.

Land, buildings, furniture and certain items specified by applicable rules or notifications are not treated in the same manner as eligible plant, machinery or equipment. The precise calculation should be verified from the applicable classification notification and the enterprise’s tax records.

For a new enterprise that has not yet filed an income-tax return, investment may initially be based on self-declaration, subject to later verification through statutory data.

Turnover calculation

Turnover information is linked to income-tax and GST records.

Export turnover is excluded for the purpose of calculating the classification turnover limits. This is intended to prevent successful exporters from losing MSME status solely because of exports.

Multiple GST registrations under one PAN

All units or GST registrations linked to the same Permanent Account Number are generally treated collectively as one enterprise for classification.

A business cannot ordinarily preserve Small status by splitting turnover among branches, GSTINs or business locations operating under the same PAN.

This is particularly relevant to groups that maintain multiple factories, offices or state-wise GST registrations under one legal entity.

The important exception: three-year continuation after upward reclassification

In October 2022, the Ministry of MSME amended the classification framework to provide transitional protection where an enterprise moves upward because of increased investment, turnover or both.

Under Notification S.O. 4926(E) dated 18 October 2022, an enterprise experiencing upward reclassification may continue to avail the non-tax benefits of its earlier category for three years from the date of upward change.

The Government’s official explanation specifically states that non-tax benefits include:

Benefits under Government schemes;
Public Procurement Policy benefits; and
Delayed-payment benefits.

The official position is recorded in the Press Information Bureau release dated 19 October 2022.

This produces an important distinction between two types of Medium Enterprises.

Enterprise that was always Medium

A business that was classified as Medium when it registered, or that did not previously hold qualifying Micro or Small status, ordinarily cannot claim the Micro and Small delayed-payment protection.

Small Enterprise reclassified as Medium

A registered Small Enterprise that is subsequently reclassified as Medium because its investment or turnover increases may continue to avail the non-tax benefits of its earlier Small category for three years from the upward change.

Since the Government expressly includes delayed-payment protection among those non-tax benefits, such an enterprise may potentially continue invoking the delayed-payment framework during the protected transitional period.

Therefore, merely looking at the word “Medium” on the latest Udyam certificate may not always answer the complete legal question. The classification history and date of upward change must also be examined.

Does the three-year protection cover every Medium Enterprise?

No. It is a transitional benefit, not a general extension of Sections 15 to 19 to all Medium Enterprises.

The claimant should be able to establish:

It was previously validly registered as a Micro or Small Enterprise;
It underwent an upward change in investment, turnover or both;
It was consequently reclassified into a higher category;
The claim falls within the three-year continuation period; and
The benefit invoked is a non-tax benefit available to the previous category.

A business that first obtained Udyam registration as a Medium Enterprise ordinarily cannot claim that it has three years of Small Enterprise protection because there was no upward reclassification from a previous registered category.

Similarly, a business that was already beyond the Small limits before registration should not artificially claim that it “graduated” merely to obtain delayed-payment rights.

Which classification applies to a particular invoice?

This question requires more care than simply saying, “Look at the status on the invoice date.”

The following dates may become relevant:

Date of Udyam registration;
Date of the contract or purchase order;
Date of commencement of supply;
Date of delivery of goods;
Date of rendering or completion of services;
Date of the invoice;
Date on which classification changed;
Date from which upward reclassification took effect; and
The three-year transitional period, if applicable.

The Supreme Court has held in cases concerning subsequent registration that a person who was not a statutory supplier when entering the relevant transaction cannot ordinarily obtain retrospective protection merely by registering later. Registration generally operates prospectively for subsequent supplies.

However, upward graduation presents a different situation because the Government has expressly preserved non-tax benefits for three years.

A proper analysis should therefore ask:

Was the enterprise a registered Small Enterprise when the transaction began?
Had it been reclassified as Medium before the supply?
Was it within the three-year non-tax transition period?
Was the particular supply made during that period?
Does the Udyam portal and official classification record support the claimed dates?
Is the enterprise invoking delayed-payment protection for a genuine manufacturing or service transaction?

For long-term contracts involving multiple supplies, each batch, milestone or invoice may require separate examination.

Are old invoices protected after the enterprise becomes Medium?

Invoices arising from supplies made while the enterprise was validly protected as a Micro or Small Enterprise do not ordinarily lose their character merely because the enterprise grows later.

For example, suppose:

A registered Small Enterprise supplied machinery in January 2025;
Payment became due in February 2025;
The enterprise was reclassified as Medium in August 2025; and
The buyer continued withholding payment.

The buyer should not ordinarily escape the accrued statutory consequences merely because the supplier subsequently grew.

The supplier’s legal status when the qualifying supply was made is highly relevant.

Where supplies are made after reclassification, the three-year transitional notification may preserve non-tax delayed-payment benefits. Once that transitional period ends, later supplies made as a Medium Enterprise ordinarily fall outside Sections 15 to 19.

Businesses should preserve historic Udyam certificates and classification records instead of retaining only the latest certificate.

Does Section 43B(h) apply to payments owed to a Medium Enterprise?

Ordinarily, no.

Section 43B(h) of the Income-tax Act provides for the disallowance of certain amounts payable to a Micro or Small Enterprise where payment is not made within the time specified in Section 15 of the MSMED Act.

The provision does not refer to amounts payable to a Medium Enterprise.

Therefore, where the vendor is legally classified as Medium for the relevant purpose, the buyer ordinarily does not face the specific Section 43B(h) disallowance merely because payment remains outstanding beyond 45 days.

However, an important distinction must be maintained:

The 2022 notification preserves non-tax benefits for three years after upward reclassification.
Section 43B(h) is a provision under the Income-tax Act imposing a tax consequence on the buyer.

The three-year continuation of non-tax benefits should not automatically be interpreted as extending Section 43B(h) to a Medium Enterprise.

There may be practical questions where the vendor was Small when the purchase occurred but became Medium before the buyer’s financial year ended. Buyers and suppliers should obtain advice based on:

The vendor’s classification on relevant dates;
The date of supply;
The date on which payment became due;
The effective date of upward reclassification;
The treatment adopted in the buyer’s books; and
Current tax guidance and judicial interpretation.

A statement printed on the invoice that “Section 43B(h) applies” does not conclusively determine the tax treatment.

What does a Medium Enterprise ordinarily lose after the transition period?

Once no Micro or Small status or transitional protection remains, an ordinary Medium Enterprise loses four major advantages.

No statutory 45-day ceiling

The enterprise becomes governed by the payment terms it contracted for, subject to general contract law.

If it accepted a valid 90-day or 120-day payment term, it cannot ordinarily replace it with the 45-day MSMED ceiling merely because it is generally an MSME.

No automatic three-times-RBI-bank-rate interest

Interest will depend on:

The contractual interest clause;
Trade usage;
The Interest Act;
The Sale of Goods Act;
The Code of Civil Procedure; or
The discretion of the court or arbitral tribunal.

A well-drafted contract should therefore provide a clear rate of interest and the date from which it becomes payable.

No MSEFC reference

A Medium Enterprise cannot ordinarily use Section 18 merely because the debt arose from a business transaction.

Its recovery forum may be a civil or commercial court, arbitral tribunal or another legally available forum.

No Section 43B(h) pressure on the buyer

The buyer ordinarily does not face the particular tax disallowance designed for delayed payment to Micro and Small Enterprises.

What should a Medium Enterprise do instead?

Loss of the special statutory route does not mean that a Medium Enterprise is defenceless. It means that its protection must come primarily from contracts, credit control and conventional recovery mechanisms.

Negotiate clear payment terms

The contract should specify:

Credit period;
Trigger date for payment;
Interest on delayed payment;
Treatment of disputed invoice portions;
Time limit for raising objections;
Consequences of failing to object;
Right to suspend supplies; and
Recovery costs and legal expenses.

Include an effective arbitration clause

The clause should identify:

Seat and venue of arbitration;
Number and appointment of arbitrators;
Language;
Governing law;
Institutional or ad hoc procedure; and
Right to seek interim protection.

A vague arbitration clause may itself generate preliminary litigation.

Obtain security

Depending upon the transaction, security may include:

Advance payment;
Irrevocable letter of credit;
Bank guarantee;
Corporate guarantee;
Personal guarantee;
Post-dated cheques;
Escrow;
Retention of title;
Charge over identified assets; or
Credit insurance.

Use TReDS where available

The Trade Receivables Discounting System may enable eligible receivables to be financed through participating financiers after acceptance by the buyer.

TReDS can improve cash flow, but it is most effective where the buyer accepts the invoice promptly. It is not a complete remedy for a buyer that disputes or refuses to approve the receivable.

Consider commercial proceedings

A Medium Enterprise may file an appropriate commercial recovery suit. Where no urgent interim relief is sought, pre-institution mediation under Section 12A of the Commercial Courts Act may be mandatory.

A summary suit under Order XXXVII of the Code of Civil Procedure may be considered where the claim falls within its requirements.

Invoke cheque-dishonour remedies

If a cheque issued against a legally enforceable liability is dishonoured, proceedings under Section 138 of the Negotiable Instruments Act may be available, provided the statutory notices and limitation periods are strictly followed.

Consider insolvency proceedings carefully

A Medium Enterprise supplying goods or services may qualify as an operational creditor under the Insolvency and Bankruptcy Code.

However, insolvency is not an ordinary debt-recovery process. The statutory threshold, limitation, existence of a genuine pre-existing dispute and the buyer’s legal status must be examined.

Why growing businesses get caught by surprise

Udyam classification is not necessarily permanent. It is dynamically connected with investment and turnover information obtained through income-tax and GST systems.

A growing business may cross the Small Enterprise ceiling because:

Turnover exceeds ₹100 crore;
Investment in plant and machinery or equipment exceeds ₹25 crore; or
One branch grows while management monitors only another unit.

Promoters sometimes continue using invoice templates stating that the business is a Small Enterprise even after official reclassification.

That can create:

Incorrect statutory-interest claims;
Defective MSEFC references;
Incorrect customer declarations;
Section 43B(h) confusion;
Accounting inconsistencies; and
Credibility problems in litigation.

The three-year non-tax transition provides breathing space, but it should be treated as a period for redesigning contracts and receivables controls—not as a reason to ignore reclassification.

Frequently Asked Questions

My Udyam certificate says “Medium.” Can I still approach the MSEFC?

If you were previously a registered Small Enterprise and were reclassified upward, you may continue to receive non-tax delayed-payment benefits for three years from the upward change. If you were always Medium, or the transition has expired, the Council route is ordinarily unavailable.

Does every Medium Enterprise receive three years of protection?

No. The protection applies upon upward reclassification from an earlier category. It is not a general benefit for every Medium Enterprise.

Does the buyer’s size matter?

No. The delayed-payment test principally concerns the supplier’s status. A Micro or Small supplier may invoke the protection against a large corporation, public-sector undertaking, partnership, individual buyer or another MSME, subject to the Act’s requirements.

Is 45 days counted from the invoice date?

Not necessarily. The Act refers to acceptance or deemed acceptance of goods or services. The invoice date may coincide with delivery, but the statutory calculation depends upon the transaction.

Can the buyer agree to pay a Small Enterprise after 90 days?

The written credit period cannot override the statutory ceiling of 45 days for an eligible supplier. For an unprotected Medium Enterprise, the contractual period may govern.

If the contract says 30 days, does the buyer get 45 days?

No. Forty-five days is the maximum ceiling, not an automatic extension. If the agreed period is 30 days, payment is due according to the 30-day term.

Is a Medium Enterprise entitled to statutory MSMED interest?

Ordinarily no, unless it is within the valid three-year continuation of delayed-payment benefits following upward reclassification or otherwise falls within a specific statutory inclusion.

Can an old Small Enterprise invoice be filed after the business becomes Medium?

Potentially yes, because the supplier’s status when the qualifying transaction occurred is highly relevant. Limitation and the three-year transitional notification must also be examined.

Does Section 43B(h) apply during the three-year transition?

The transition expressly preserves non-tax benefits. Section 43B(h) is a tax provision and should not automatically be treated as extended by that notification. Specific tax advice is necessary.

What happens if turnover exceeds the limit but investment remains below it?

Exceeding either ceiling can trigger upward classification. Both limits must be satisfied to remain within a category.

Is export turnover included?

Export turnover is excluded when applying the MSME classification turnover criterion, subject to the applicable notification and data records.

Can separate GST registrations remain separate Small Enterprises?

Not ordinarily where they belong to the same PAN. Turnover and investment are generally aggregated across units linked to the same PAN.

Can related companies with separate PANs be treated separately?

Separate legal entities with separate PANs may be separately classified, but artificial restructuring, sham arrangements or diversion of turnover may be challenged. Corporate, tax, beneficial-ownership and commercial consequences must be considered.

Can a business refuse growth to remain Small?

A business may legitimately plan investment and operations, but artificial suppression or fragmentation of turnover can create serious tax, regulatory and commercial risks. Classification should not be manipulated through false declarations.

Does Udyam registration automatically update?

Classification is linked to income-tax and GST information, but businesses must still comply with portal requirements and keep their records updated. The current certificate and classification history should be reviewed periodically.

Can a Medium Enterprise mention an MSME declaration on invoices?

It may accurately state that it is a Medium Enterprise registered under Udyam. It should not inaccurately claim Micro or Small delayed-payment rights unless transitional protection genuinely applies.

If the MSEFC rejects the reference, is the debt lost?

No. Rejection of the forum does not ordinarily extinguish the underlying debt. The enterprise may pursue a civil or commercial suit, arbitration or another available remedy. Limitation must be protected immediately.

Can Medium Enterprises use MSME Samadhaan just to send a notice?

The portal and Section 18 mechanism are intended for eligible Micro and Small suppliers. Filing an ineligible claim merely to create pressure may waste time and expose the claimant to a jurisdictional objection.

Are there proposals to extend protection to Medium Enterprises?

MSME classifications and policies have evolved over time. However, recovery planning should be based on enacted law and operative notifications, not proposed amendments or public statements.

Practical takeaway

A Medium Enterprise is not ordinarily protected by the 45-day rule merely because it falls within the wider MSME sector.

The correct analysis is:

Was the enterprise previously registered as Micro or Small?
When did its upward reclassification take effect?
Is it within the three-year continuation of non-tax benefits?
When were the contract, supply and invoice issued?
Does the claim arise from a qualifying manufacturing or service activity?
Is the claimant seeking an MSMED non-tax benefit or relying on Section 43B(h), which is a separate tax provision?

An enterprise that was always Medium ordinarily remains outside Sections 15 to 19. A Small Enterprise that has recently graduated to Medium may continue to receive delayed-payment protection during the three-year transitional period.

Growing enterprises should use that transition to strengthen contracts, security instruments, buyer-credit checks, invoice acceptance systems, arbitration clauses and recovery processes. Statutory protection may reduce after graduation, but disciplined documentation and receivables management can provide an equally important commercial shield.
