HR Compliance Calendar 2026-27: Monthly Deadlines Every Indian Business Must Know
What Are the 3 Non-Negotiable Monthly Compliance Deadlines in India?
Every Indian employer must meet three recurring payroll compliance deadlines each month without exception. First, the TDS (Tax Deducted at Source) deposit must reach the government by the 7th of every month via Challan 281. Second, the Provident Fund (PF) contribution along with ECR filing must be completed by the 15th. Third, the ESI (Employees’ State Insurance) contribution is also due by the 15th. Missing even one of these deadlines triggers automatic interest charges and penalties that compound rapidly. There are no grace periods, no warnings, and no exceptions for small businesses.
This comprehensive HR compliance calendar covers every monthly, quarterly, half-yearly, and annual HR and payroll compliance deadline for FY 2026-27 (April 2026 to March 2027). It incorporates the sweeping changes brought by the Income Tax Act 2025 (replacing the 1961 Act), the new TDS return forms (Form 138 replacing Form 24Q, Form 140 replacing Form 26Q), and the New Labour Codes that became effective in November 2025. Whether you employ 5 people or 500, this calendar ensures you never miss a filing date, never pay avoidable penalties, and never face enforcement action from the EPFO, ESIC, or Income Tax Department.
Tools like SalaryBox — a mobile-first attendance and payroll app built for Indian SMBs — automate PF, ESI, and TDS calculations with built-in compliance reminders. With AI selfie attendance, GPS geofencing, and automated payroll, SalaryBox is free for up to 25 employees, making compliance accessible for businesses of every size.

What Does the Month-by-Month HR Compliance Calendar Look Like for FY 2026-27?
Below is the complete month-by-month breakdown of every compliance deadline from April 2026 through March 2027. Each month lists the exact date, the obligation, and any special notes. Use this as your master checklist throughout the financial year.
April 2026 — Start of New Financial Year
- 7 April: TDS deposit for March 2026 salaries via Challan 281. Note: For the month of March, the government extends the TDS deposit deadline to 30 April, so the 7 April date applies only to non-salary TDS.

What Are the Penalties for Missing HR Compliance Deadlines?
Non-compliance with payroll and HR statutory deadlines carries severe financial and legal consequences in India. The penalties are automatic in most cases — there is no warning system, no first-offence waiver, and no discretionary relief. The table below summarises the penalties for each type of violation. Understanding these consequences helps quantify the cost of non-compliance and justifies investment in automated compliance tools.
| Compliance Area | Penalty / Interest | Legal Reference |
| PF Late Deposit | 12% interest p.a. on delayed amount + damages ranging from 5% to 25% of arrears depending on delay duration | Section 14B, EPF & MP Act 1952; Para 32A of EPF Scheme |
| ESI Late Deposit | 12% interest per annum on the amount of contribution due. Persistent default may lead to prosecution. | Section 85(a), ESI Act 1948 |
| TDS Late Deposit | 1.5% interest per month (or part of month) from the date of deduction to the date of actual deposit. Interest is calculated monthly, not daily. | Section 201(1A), Income Tax Act 2025 (formerly Section 201 of IT Act 1961) |
| TDS Late Filing | Rs 200 per day under Section 234E until the return is filed, capped at the total TDS amount. Late filing fee applies even if all TDS was deposited on time. | Section 234E, Income Tax Act 2025 |
| TDS Penalty | Rs 10,000 minimum to Rs 1,00,000 maximum for failure to file TDS return within one year of the due date or furnishing incorrect information in the return. | Section 271H, Income Tax Act 2025 |
| Professional Tax | Varies by state. Typically Rs 500 to Rs 5,000 per instance. Some states (Maharashtra) charge 1.25% interest per month on delayed payment. | State-specific Professional Tax Acts |
| Bonus Late Payment | Fine of Rs 1,000 to Rs 2,000 and/or imprisonment up to 6 months. Both the company and responsible officers can be prosecuted. | Section 28, Payment of Bonus Act 1965 |
| Wages Late Payment | Fine of Rs 1,500 to Rs 7,500 per violation. Repeat offence attracts higher penalty and potential imprisonment up to 1 month. | Section 20, Payment of Wages Act 1936 |
Bottom line: A single missed PF deadline on a 50-employee payroll of Rs 10 lakhs can trigger Rs 12,000 in annual interest plus up to Rs 2,50,000 in damages. Automated compliance tools like SalaryBox eliminate these risks by calculating contributions in real-time and generating payment challans before every deadline.
What Changed in 2026-27 Compliance? Key Regulatory Updates
FY 2026-27 brings some of the most significant regulatory changes to Indian payroll compliance in decades. HR and payroll professionals must understand these changes to avoid inadvertent non-compliance. Here are the five major updates that affect every Indian employer.
1. Income Tax Act 2025 Replaces the 1961 Act
The new Income Tax Act 2025 came into effect from 1 April 2026, replacing the six-decade-old Income Tax Act 1961. While the substantive tax provisions remain largely similar, the section numbering, form numbers, and procedural references have changed entirely. All internal processes, tax computation sheets, and compliance checklists must be updated to reference the new Act and its section numbers. Training payroll staff on the new framework is essential.
2. New TDS Return Forms: Form 138 and Form 140
Form 24Q (quarterly TDS return for salary payments) has been replaced by Form 138 under the new Act. Similarly, Form 26Q (TDS on non-salary payments) is now Form 140. The form structure and data fields are largely unchanged, but filing must be done using the new form numbers on the TRACES portal. Any filing under the old form numbers will be rejected. SalaryBox has updated its TDS export modules to generate data in the new Form 138 format automatically.
3. New Labour Codes and the 50% Basic Salary Rule
The four New Labour Codes (Code on Wages, Industrial Relations Code, Social Security Code, and OSH Code) became effective in November 2025. The most impactful provision for payroll is the wage definition under the Code on Wages: basic salary plus dearness allowance must constitute at least 50% of total remuneration. This means companies that previously structured salaries with a low basic component (say 30-40%) now face higher PF contribution costs, as PF is calculated on basic salary. HR teams must restructure CTC breakups accordingly.
4. Updated TDS Slab Rates for FY 2026-27
The new tax regime (default regime under the Income Tax Act 2025) has updated slab rates for individual taxpayers. Employers must apply the correct slab rates when computing TDS on salaries. The old regime remains available as an opt-in choice, but employees must explicitly elect it. Payroll systems must support dual-regime TDS computation. SalaryBox handles both regime calculations and allows employees to switch regimes via the app with automatic TDS recalculation.
5. Digital Compliance and E-verification Requirements
EPFO and ESIC have progressively digitised their compliance frameworks. Aadhaar-based e-KYC is now mandatory for all new PF registrations. ESI claims processing is fully online. The Income Tax Department requires digital signatures for all employer TDS returns. These digital requirements mean that manual, paper-based compliance processes are no longer viable. Employers must adopt digital payroll and compliance platforms to meet regulatory expectations.
What Are the Quarterly, Half-Yearly, and Annual Compliance Deadlines?
Beyond the monthly deadlines, Indian employers must also meet periodic compliance obligations on a quarterly, half-yearly, and annual basis. The table below consolidates all non-monthly deadlines for quick reference.
| Frequency | Deadline | Obligation | Form / Portal |
| Quarterly | 31 July 2026 | Q1 TDS Return (Apr-Jun) | Form 138 on TRACES |
| Quarterly | 31 October 2026 | Q2 TDS Return (Jul-Sep) | Form 138 on TRACES |
| Quarterly | 31 January 2027 | Q3 TDS Return (Oct-Dec) | Form 138 on TRACES |
| Quarterly | 31 May 2027 | Q4 TDS Return (Jan-Mar) | Form 138 on TRACES |
| Half-Yearly | 25 May 2026 | ESI Return (Oct-Mar period) | ESIC Portal |
| Half-Yearly | 25 November 2026 | ESI Return (Apr-Sep period) | ESIC Portal |
| Annual | 15 June 2026 | Issue Form 16 (FY 2025-26) | Generated from TRACES |
| Annual | 31 July 2026 | Annual PF Return | EPFO Unified Portal |
| Annual | 31 July 2026 | ITR Filing (non-audit) | Income Tax e-filing Portal |
| Annual | 31 October 2026 | ITR Filing (audit cases) | Income Tax e-filing Portal |
| Annual | 30 September 2026 | Bonus payment (Jan year-end) | Payment of Bonus Act 1965 |
| Annual | 31 March 2027 | Gratuity valuation + Leave encashment reconciliation + FY close | Internal payroll records |
Tip: Set calendar alerts for each of these periodic deadlines at least one week in advance. Better yet, use SalaryBox’s automated compliance reminder system, which sends push notifications to your phone 7 days, 3 days, and 1 day before every deadline — monthly, quarterly, half-yearly, and annual.
How Can SalaryBox Help You Stay Compliant Throughout FY 2026-27?

Frequently Asked Questions About HR Compliance Calendar 2026-27
Q1: What happens if my PF payment is delayed by just one day?
Even a single day of delay triggers the 12% per annum interest charge under Section 14B of the EPF Act. In addition, the EPFO Regional Commissioner can levy damages ranging from 5% to 25% of the arrear contribution amount depending on the length of delay. There is no grace period or waiver for first-time offenders. The interest is calculated from the 16th of the month (the day after the due date) until the actual date of deposit. Automated payroll tools like SalaryBox ensure contributions are calculated and challan data is ready well before the 15th.
Q2: Is the TDS deposit deadline of 7th applicable to all types of TDS?
Yes, the 7th of every month is the deadline for depositing TDS deducted during the previous month, applicable to both salary (Section 192) and non-salary TDS. The only exception is TDS deducted in March, where the deadline extends to 30th April. For government deductors, TDS must be deposited on the same day of deduction. The penalty for late deposit is 1.5% per month interest from the date of deduction, not from the due date. This means the interest clock starts ticking from the actual date you deducted TDS from the employee’s salary.
Q3: What are the new form numbers for TDS returns under the Income Tax Act 2025?
Under the Income Tax Act 2025 (effective 1 April 2026), Form 24Q for quarterly salary TDS returns is replaced by Form 138. Form 26Q for non-salary TDS returns is replaced by Form 140. The TRACES portal has been updated to accept filings only under the new form numbers. The data fields and structure remain substantially similar to the old forms, but employers must update their payroll software and processes to reference the new form numbers. SalaryBox already generates TDS data exports in the Form 138 format.
Q4: How does the 50% basic salary rule under the New Labour Codes affect PF?
Under the Code on Wages, basic salary plus dearness allowance must constitute at least 50% of an employee’s total remuneration (CTC). Previously, many companies structured salaries with basic at 30-40% of CTC, with the rest distributed as HRA, special allowance, and other components. Since PF is calculated on basic salary, this restructuring effectively increases the PF-eligible wage base and consequently the employer’s PF contribution cost. Companies that have not yet restructured their salary breakups to comply with this rule risk retrospective PF liability claims from the EPFO.
Q5: Can I file the ESI half-yearly return after the 25th May / 25th November deadline?
While the ESI return can technically be filed after the deadline, late filing may attract penalties and scrutiny from the ESIC. The half-yearly return for October-March is due by 25th May, and the April-September return is due by 25th November. The return must include details of all covered employees, their wages, contributions paid, and any accident or sickness benefit claims. Filing late can delay employee benefit disbursements and trigger inspection notices.
Q6: Is Professional Tax applicable in all Indian states?
No, Professional Tax is not levied by all states. As of FY 2026-27, states that impose Professional Tax include Maharashtra, Karnataka, West Bengal, Andhra Pradesh, Telangana, Tamil Nadu, Gujarat, Madhya Pradesh, Kerala, Assam, Meghalaya, Odisha, Tripura, Jharkhand, Bihar, Chhattisgarh, and Sikkim. The rates, slabs, and payment frequency (monthly or half-yearly) vary by state. The maximum Professional Tax allowed under the Indian Constitution is Rs 2,500 per person per year. Employers must register for PT in each state where they have employees and deduct it from employee salaries.
Q7: When should I start collecting investment proofs for year-end TDS computation?
The practical timeline is: collect updated investment declarations by 15th January, set a deadline for submission of actual proofs by end of February, and finalize TDS computations in the first week of March for the March payroll. Starting this process late creates two risks: under-deduction of TDS (resulting in employer liability for the shortfall) or over-deduction (causing employee dissatisfaction and refund claims). SalaryBox streamlines this by allowing employees to upload proof documents via the mobile app throughout the year, with automated reminders starting in January.
Q8: How can a small business with fewer than 25 employees manage all these deadlines?
Small businesses are subject to most of the same compliance deadlines as large enterprises. The key difference is scale, not scope. PF registration is mandatory once you have 20+ employees (10+ in some notified establishments). ESI applies if wages are below Rs 21,000 per month. TDS applies regardless of company size if you pay salaries above the basic exemption limit. SalaryBox is free for businesses with up to 25 employees and automates PF, ESI, and TDS calculations, generates compliant challans, sends deadline reminders, and provides a compliance dashboard. This makes enterprise-grade compliance accessible to even the smallest businesses without hiring a dedicated payroll specialist.
Disclaimer: This compliance calendar is intended for general informational purposes only and does not constitute legal or tax advice. Compliance deadlines are based on information available as of July 2026 and may be subject to change through government notifications, circulars, or amendments. Always verify deadlines with official government portals (EPFO, ESIC, Income Tax e-filing) and consult a qualified tax professional or legal advisor for compliance decisions specific to your business.
