Monthly Statutory Compliance in Mumbai – Complete 2026 Guide to PF, ESIC, PT, TDS, MLWF & All Labour Law Deadlines

Section 1: Why Monthly Compliance is Critical for Mumbai Businesses

The Cost of Missing One Month

Consider a mid-sized Mumbai business with 50 employees that misses PF deposit for one month. The missed deposit attracts 12% per annum interest from Day 1. If the same business consistently misses deposits for 6 months, Section 14B damages of 25% per annum kick in on top of the interest. A ₹1 lakh monthly PF liability ignored for 6 months can generate ₹25,000 in damages alone — before interest, before legal fees, before management time spent handling notices.

The Compounding Effect of Non-Compliance

Statutory non-compliance rarely stays as a single missed payment. It compounds. A missed PF deposit leads to an EPFO notice. An ignored notice leads to a Section 7A assessment. An assessment leads to a demand order. A demand order leads to property attachment. What started as a ₹50,000 cash flow decision can end as a ₹5 lakh legal liability — plus criminal prosecution of the business owner.

Employee Awareness is at an All-Time High

Employees in Mumbai in 2026 check their PF passbook on the UMANG app. They see missing deposits within weeks — not years. They know how to file EPFO grievances online. One employee complaint triggers an inspection that reviews the entire establishment's compliance history. Monthly compliance prevents this chain from starting.

EPFO 3.0 Makes Detection Faster

EPFO's new AI-based monitoring system cross-references ECR data with GST filings and income tax returns in real time. Anomalies — inconsistent wage reporting, missing filings, sudden employee count changes — are flagged automatically for inspection. Monthly compliance gaps that previously went undetected for years are now being caught far more quickly.

Section 2: Complete Monthly Statutory Compliance Calendar 2026

Here is the complete month-by-month statutory compliance calendar for every Mumbai business:

7th of Every Month

TDS on Salaries (Section 192) — deposit TDS deducted from employee salaries during the previous month to the Income Tax Department through Challan 281. This is a hard deadline — even one day's delay attracts interest at 1.5% per month.

10th of Every Month

GST Returns — GSTR-1 (outward supplies) for regular taxpayers due by the 11th. GSTR-3B (summary return and tax payment) due by the 20th for most taxpayers. Relevant for businesses registered under GST.

15th of Every Month

• PF Contribution Deposit and ECR Filing — deposit both employee and employer PF contributions and simultaneously file the Electronic Challan cum Return (ECR) on the EPFO Unified Employer Portal. Both must happen by the 15th — deposit alone without ECR filing or ECR without deposit are both non-compliant.
• ESIC Contribution Deposit — deposit both employee (0.75%) and employer (3.25%) ESIC contributions on the ESIC employer portal for all covered employees for the previous month.
• Professional Tax Remittance — remit PT deducted from employee salaries to the Maharashtra GST Department (for establishments with more than 20 employees who are on monthly PT remittance schedule).

Last Working Day of Every Month

Wage Payment — under the Payment of Wages Act, all wages for the month must be paid to employees by the last working day of that wage month. No wages can be withheld beyond this date without legal consequence.

Throughout Every Month — Ongoing Actions

• New joiner PF onboarding — generate UAN, activate, seed Aadhaar, and approve KYC on EPFO employer portal within the first week of every new employee joining.
• New joiner ESIC registration — generate IP number for every new covered employee (gross salary below ₹21,000/month) upon joining.
• Employee exit date updates — update Date of Exit on EPFO portal within 7 days of every employee's last working day.
• Contractor compliance verification — collect monthly ECR and ESIC challan receipts from contractors whose workers are on your premises.

Section 3: PF Monthly Compliance — ECR Filing and Contribution Deposit

What Must Be Done Every Month

• Step 1 — Complete payroll for the previous month and compute PF contribution for every covered employee on their Basic + DA.
• Step 2 — Log in to the EPFO Unified Employer Portal (unifiedportal-epfo.epfindia.gov.in). Generate or upload the ECR file. The ECR must include, for every EPF member: UAN, name, wages (Basic + DA), employee's EPF share, employer's EPF share, pension (EPS) contribution, and member type (regular, new joiner, exit).
• Step 3 — Verify the ECR summary against your payroll records. Every new joiner must be included. Every departing employee must be shown with their exit date.
• Step 4 — Generate the challan and pay the total contribution online. Save the payment confirmation receipt.

Key Rules

• PF contribution base is Basic + DA only — not gross salary. HRA, travel allowance, and other allowances are excluded.
• Deposit deadline is the 15th — not the last day of the month. Monthly salary is often paid at month end but PF must be deposited by the 15th of the following month regardless.
• New joiners must appear in their first ECR even for a partial month — with pro-rated wages and contributions for the days actually worked.

Common Mistakes That Trigger EPFO Notices

• Missing new joiners in ECR.
• Not updating exit members.
• Wage amounts in ECR not matching actual payroll.
• Filing ECR without depositing or depositing without filing.
• Using gross salary instead of Basic + DA.

Section 4: ESIC Monthly Compliance — Contribution Deposit

What Must Be Done Every Month

• Step 1 — Identify all covered employees — those earning gross wages up to ₹21,000 per month. Review this list at the start of every contribution period (April 1 and October 1) for wage ceiling changes.
• Step 2 — Compute ESIC contributions: Employee share = 0.75% of gross wages. Employer share = 3.25% of gross wages. Note that ESIC base is gross wages — unlike PF which uses only Basic + DA.
• Step 3 — Log in to esic.in. Generate monthly contribution challan and pay online.

Important: Unlike PF where both ECR filing and deposit are simultaneous, ESIC requires separate monthly contribution payment and a separate half-yearly return. The monthly challan is not a return — the formal returns are due on November 12 (for April–September period) and May 12 (for October–March period).

ESIC Wage Ceiling Compliance

At the start of every new contribution period (April 1 and October 1), review all employees' gross salaries against the ₹21,000 ceiling. Employees whose salary has risen above ₹21,000 since the last review should be excluded from the new contribution period. New employees joining below ₹21,000 must be enrolled. Failure to do this bi-annual review creates systematic under-coverage or over-contribution errors.

Section 5: TDS on Salaries — Monthly Deposit Obligation

What Must Be Done Every Month

Deduct TDS from every employee's salary in the monthly payroll run based on their estimated annual tax liability — accounting for their declared investments (Form 12BB), applicable exemptions (HRA, LTA), and standard deduction.

Deposit the deducted TDS with the Income Tax Department by the 7th of the following month through Challan 281 (online payment via the Income Tax TIN-NSDL portal). For March deductions, the deposit deadline is April 30th.

What TDS on Salary Covers

• Monthly salary components (basic, DA, HRA, allowances).
• Bonus and incentives paid during the month.
• Perquisites valued at taxable amounts.
• Arrears paid during the month.

Critical Points

For new joiners in the middle of the financial year — collect Form 12B (declaration of salary from previous employer for the current year) and include that income in your TDS computation for the remaining months. Ignoring the previous employer's income leads to massive TDS shortfall at year-end and makes the employer liable.

Conduct a mid-year TDS review in September-October. Collect revised investment declarations from all employees. Adjust TDS for the October to March period based on actual investments made vs what was declared in April.

Quarterly TDS Returns

In addition to monthly deposit, quarterly TDS returns must be filed in Form 24Q:

• Quarter 1 (April–June) — due July 31
• Quarter 2 (July–September) — due October 31
• Quarter 3 (October–December) — due January 31
• Quarter 4 (January–March) — due May 31

Issue Form 16 to all employees by June 15th each year after filing the Q4 return.

Section 6: Professional Tax — Monthly Remittance

Applicability in Mumbai

Professional Tax under the Maharashtra State Tax on Professions, Trades, Callings and Employments Act, 1975, applies to all employees in Maharashtra earning above ₹7,500 per month in gross salary.

PT Slabs for 2026

• Gross salary up to ₹7,500 per month — Nil
• Gross salary ₹7,501 to ₹10,000 per month — ₹175 per month
• Gross salary above ₹10,000 per month — ₹200 per month (₹300 in February)

Note: February PT is ₹300 for employees in the above-₹10,000 slab. This makes the annual total ₹2,500 (₹200 × 11 months + ₹300 × 1 month). This February difference is the most frequently missed payroll detail in Mumbai.

PT Remittance Schedule

• Establishments with more than 20 employees — monthly PT remittance by the last day of the following month (May deductions remitted by June 30).
• Establishments with 20 or fewer employees — annual remittance by March 31st covering the full year's PT deductions.

Two Separate PT Registrations Required

• Registration Certificate (RC) — for employers to deduct and remit employee PT.
• Enrollment Certificate (EC) — for the employer entity to pay its own PT liability of ₹2,500 per year by June 30th.

Both are mandatory and both must be separately maintained.

Section 7: MLWF — Biannual Compliance (June and December)

What is MLWF

The Maharashtra Labour Welfare Fund (MLWF) is a statutory welfare fund under the Maharashtra Labour Welfare Fund Act, 1953. It funds worker welfare services — educational scholarships, vocational training, medical facilities, housing loans, marriage assistance, and recreational facilities for workers across Maharashtra.

Who Must Contribute

All establishments in Mumbai covered under the Factories Act or the Maharashtra Shops and Establishments Act — which covers virtually every business — must contribute.

Contribution Rates

• Employee share: ₹25 per contribution period
• Employer share: ₹75 per contribution period
• Total per employee per cycle: ₹100

Payment Schedule

• June 30th — for the January to June contribution period.
• December 31st — for the July to December contribution period.

Annual Return

File the annual MLWF return with the Maharashtra Labour Welfare Board (mlwb.maharashtra.gov.in) within the prescribed deadline covering full year employee-wise contribution details.

Why MLWF is Frequently Missed

Unlike PF and ESIC which are monthly — MLWF is biannual. The June 30th deadline comes during year-end activities and the December 31st deadline coincides with calendar year end — both high-distraction periods where this obligation is easily forgotten. Interest at 2% per month applies on delayed MLWF contributions.

Section 8: Payment of Wages — Monthly Obligation

The Law

Under the Payment of Wages Act, 1936, all wages for a given month must be paid to employees by the last working day of that month. No wages can be withheld beyond this date.

Specific Rules for Mumbai Businesses

• Establishments employing fewer than 1,000 persons — wages must be paid by the 7th of the following month (some interpretations) or last working day of the month (safest practice).
• Wages must be paid in full — no unauthorised deductions are permitted. Only lawful deductions (TDS, PF, ESIC, PT, loans and advances with written consent) are permitted.

Full and Final Settlement

Under the Payment of Wages Act, F&F settlement wages must be paid within 2 working days of separation for establishments with fewer than 1,000 employees. Delays attract a fine up to ₹50,000 for first offence and ₹1,00,000 for repeat under the Act.

Salary Register and Wage Records

Every employer must maintain a wage register (Register of Wages) showing month-wise gross wages, all deductions, and net wages paid for every employee. This register is reviewed during labour inspections and must be maintained for a minimum of 3 years.

Section 9: Annual and Periodic Compliance Tied to Monthly Actions

Monthly compliance is the foundation — but several annual and periodic obligations flow from monthly compliance actions:

Annual PT Return — June 30th

Summary of all employee-wise PT deductions and remittances for the financial year. Payment of employer's Enrollment Certificate PT of ₹2,500.

ESIC Half-Yearly Returns — November 12 and May 12

Formal return filing on ESIC portal summarising contributions for each six-month period. Many businesses that pay ESIC monthly still receive notices because they skip the formal half-yearly return.

Annual TDS Return (Form 24Q) — May 31st

Summary of all TDS deducted and deposited on salaries for the full financial year. Form 16 must be issued to all employees within 15 days of filing.

Annual Bonus — Payment of Bonus Act

Minimum bonus of 8.33% of salary (capped at ₹7,000/month) payable to eligible employees within 8 months of the close of the accounting year. Customarily paid at Diwali in Mumbai.

Maharashtra Shops Act Annual Renewal

Every business operating in Mumbai must renew their Maharashtra Shops and Establishments registration annually before expiry. Renewal is online on the Maharashtra Udyog portal.

Minimum Wage Revision Review — January and July

Maharashtra minimum wages are revised twice annually. Review and update all employee salaries for compliance every January and July when new rates are notified.

Section 10: Penalties for Missing Deadlines — Quick Reference

Section 12: Why You Need a Monthly Compliance Partner in Mumbai

Managing monthly statutory compliance in Mumbai is not a one-time project — it is an ongoing, relentless operational requirement. Every month brings the same set of deadlines, the same calculations, and the same consequences for errors.

Most Mumbai business owners manage their core business — operations, clients, growth — while compliance either gets delegated to a stretched HR or accounts team or gets done reactively after notices arrive. Neither approach is sustainable as a business grows.

A professional monthly compliance partner handles every obligation systematically — calculating, filing, depositing, reconciling, and reporting — so you are always compliant, always on time, and never caught by a surprise notice.

What a Monthly Compliance Partner Does for You

• Tracks every deadline across PF, ESIC, TDS, PT, MLWF, and labour law — no deadline is missed.
• Computes all statutory contributions accurately — right salary base, right rates, right period.
• Files all returns and uploads all challans — ECR, ESIC challan, TDS Challan 281, PT remittance.
• Manages employee lifecycle compliance — UAN activation, ESIC registration, KYC approvals, exit date updates.
• Responds to statutory notices — show-cause notices, demand letters, inspection queries.
• Updates you on regulatory changes — new minimum wages, revised contribution rates, new EPFO and ESIC circulars.
• Provides monthly compliance reports — a clean summary every month confirming what was filed, what was paid, and any issues identified.

At HN Gupta & Co., Mumbai

We provide end-to-end monthly statutory compliance services for businesses across Mumbai, Thane, and Navi Mumbai — from single-location SMEs to multi-branch corporations. Our systematic, calendar-driven approach ensures zero compliance gaps, zero missed deadlines, and zero surprise notices.

Section 13: Frequently Asked Questions

What is included in monthly statutory compliance for a Mumbai business?

For a typical Mumbai business with 20+ employees, monthly statutory compliance covers: PF contribution deposit and ECR filing (by 15th), ESIC contribution deposit (by 15th), TDS on salaries deposit (by 7th), Professional Tax remittance (by last day of following month for 20+ employee businesses), wage payment to all employees (by last working day), and ongoing employee lifecycle actions — UAN activation, ESIC registration, exit date updates. Additionally, MLWF is due biannually (June 30 and December 31) and quarterly TDS returns must be filed.

What happens if we miss the PF deposit deadline by even a few days?

Interest at 12% per annum runs from the 16th of the month (the day after deadline). For consistent delays of 4 to 6 months, Section 14B damages of 15% per annum are added on top of interest. The total cost of missed deposits compounds rapidly. There is no grace period — the law starts running from the due date.

We are a startup with 15 employees in Mumbai. Which monthly compliances apply to us?

With 15 employees you are below the 20-employee PF threshold (unless you voluntarily registered) and below ESIC's 10-employee threshold (you should already be registered if you have 10+ employees). Applicable obligations include: TDS on salaries (from day 1 if employees earn above basic exemption), Professional Tax (from day 1 if any employee earns above ₹7,500 gross), Payment of Wages Act compliance (wages paid on time), and MLWF. PF and ESIC will become mandatory when you cross 20 and 10 employees respectively.

Can one service provider handle all monthly statutory compliance for our Mumbai business?

Yes. A full-service monthly compliance provider like HN Gupta & Co. handles all obligations — PF, ESIC, TDS, PT, MLWF, and labour law — under one roof. This is significantly more efficient than managing separate relationships for each compliance area, and ensures nothing falls through the gaps between providers.

How do we ensure our contractors' workers are PF and ESIC compliant?

As principal employer, you are ultimately liable for PF and ESIC compliance of contractors' workers working on your premises if the contractor defaults. Best practice: require monthly proof of compliance (ECR and ESIC challan receipts) from every contractor before releasing their monthly payment. Include PF and ESIC compliance as a mandatory contractual condition. If a contractor defaults and you have paid them without verifying compliance, you are exposed.

What is the difference between the 15th deadline for PF and the 7th deadline for TDS?

TDS on salaries must be deposited by the 7th of the following month — this is a monthly deposit obligation. PF contributions (along with ECR filing) must be deposited by the 15th of the following month. Both are mandatory, both carry penalties for delay, and both must be tracked separately. A payroll compliance calendar that treats the 7th as a firm internal TDS deadline and the 15th as the firm PF and ESIC deadline eliminates the most common monthly compliance failures.
