The main types of accrued leave are earned leave (privilege leave), accrued sick leave, compensatory leave, and in some contexts, casual leave — each governed by different accrual rates, usage rules, and payout eligibility criteria.
1. Earned Leave (Privilege Leave / Annual Leave)
Earned leave — also called privilege leave or annual leave depending on the organisation — is the primary form of accrued leave and the one most commonly associated with the accrual concept. It is earned through active service and typically carries the most generous accrual rate. Under the Factories Act, 1948, the minimum entitlement is one day of earned leave for every 20 days of work. Under the Shops and Establishments Acts (which apply to commercial establishments), entitlements vary by state but are generally more generous.
Earned leave is the form of leave most commonly subject to carry-forward limits, year-end encashment programmes, and full payout on exit. It is the primary component of an employee's leave encashment entitlement at the time of resignation, retirement, or termination.
2. Accrued Sick Leave
Accrued sick leave is the stock of paid sick leave an employee has accumulated but not yet used. While casual sick leave is typically granted as a fixed annual entitlement (e.g., 10 days at the start of the year), some organisations operate an accrual model for sick leave as well — accumulating sick leave credits incrementally across the year rather than granting the full entitlement upfront.
A key difference between accrued sick leave and accrued earned leave is the payout eligibility. In most Indian organisations and under most state Shops and Establishments Acts, unused sick leave is not encashable at the time of exit — it lapses when the employee leaves or at the end of the leave year, depending on the carry-forward policy. Some organisations allow limited carry-forward of sick leave (for example, up to 30 days) to give employees a buffer for extended illness without financial hardship.
3. Compensatory Leave (Comp-Off)
Compensatory leave is accrued when an employee works on a declared holiday, a weekly off, or beyond standard hours in a manner that entitles them to time off in lieu. The comp-off is accrued at the time the extra work is performed and is typically subject to a validity period — meaning it must be taken within a defined window (often 30 to 60 days) or it lapses. Comp-off accruals are common in organisations with project-driven work cultures, shift-based operations, and customer support teams.
4. Casual Leave
Casual leave is typically granted as a fixed annual entitlement rather than an accrual, meaning employees receive the full year's casual leave credit at the beginning of the leave year. However, some organisations operate casual leave on a monthly accrual basis — particularly for employees joining mid-year — making it a form of accrued leave in practice. Casual leave that is unused at year-end typically lapses and is neither carried forward nor encashed, distinguishing it from earned leave.
5. Maternity and Paternity Leave Accruals
Under the Maternity Benefit Act, 1961 (as amended in 2017), female employees are entitled to 26 weeks of paid maternity leave. The period of maternity leave counts toward service continuity for the purposes of earned leave accrual. Male employees covered by paternity leave policies — where applicable — similarly continue to accrue earned leave during their paternity leave period.
Comparison of Accrued Leave Types — Key Differences
| Leave Type | Accrual Basis | Carry-Forward? | Encashable on Exit? | Indian Law Basis |
| Earned Leave (EL) | Monthly/proportional | Yes (up to policy limit) | Yes | Factories Act 1948, S&E Acts |
| Accrued Sick Leave | Monthly/fixed grant | Limited (policy-specific) | Generally No | S&E Acts (state-wise) |
| Casual Leave | Annual grant / monthly accrual | Usually No (lapses) | No | S&E Acts (state-wise) |
| Compensatory Off | Per instance (overtime/holiday) | Yes (with validity period) | Policy-specific | Factories Act / Policy |
| Maternity Leave | Statutory grant (not accrued) | Not applicable | Not applicable | Maternity Benefit Act 1961 |
