Leave Carryover Cap: Definition, Rules and Country Limits

A leave carryover cap is the maximum amount of unused annual leave an employee may transfer from one leave year into the next. Anything above the cap lapses at year end, unless a statutory right to carry it over applies.

That exception does a lot of work. In the UK, part of the statutory entitlement must carry over in defined circumstances no matter what your policy says. In Australia and New Zealand, accrued annual leave does not lapse at all, which makes a forfeiting cap the wrong tool entirely.

Key takeaways

• A carryover cap is applied once, at the end of the leave year, to the unused balance.
• UK statutory leave is 5.6 weeks, split into 4 weeks under Regulation 13 and 1.6 weeks under Regulation 13A of the Working Time Regulations 1998 (legislation.gov.uk).
• Workers who could not take leave because of long-term sickness may carry over up to four weeks of statutory leave (GOV.UK).
• In Australia, annual leave accumulates from year to year and does not expire (Fair Work Ombudsman).
• Caps belong on contractual leave above the statutory minimum, paired with an expiry date early in the new year.

What Is a Leave Carryover Cap?

A leave carryover cap sets a ceiling on unused annual leave rolling forward into the next leave year. It is a year-end rule, applied to a single balance at a single moment, and it should always come with a companion rule: a deadline by which the carried leave must be used.

A typical clause reads: “Employees may carry forward a maximum of five days of unused annual leave. Carried-forward leave must be taken by 31 March, after which it will lapse.”

Two numbers make the policy: the cap (how much moves) and the expiry (how long it survives). A cap without an expiry date quietly builds a permanent balance instead of controlling one.

How Does a Carryover Cap Work in Practice?

The cap applies to whatever is left once the leave year closes, not continuously through the year. The sequence is always the same:

1. Close the leave year and calculate the unused balance.
2. Identify any leave that must carry over by law, and set it aside from the cap.
3. Apply the cap to the remaining discretionary balance.
4. Lapse anything above the cap and record the decision.
5. Stamp the carried days with an expiry date.

Step two is where policies go wrong. Apply the cap to the whole balance without separating out statutorily protected leave and you can extinguish an entitlement the employee is legally owed.

Your policy should also state which portion of leave is deemed used first. The days left at year end are whichever portion your policy consumes last, so setting that order in writing is what makes the calculation defensible.

Worked Example: A Five-Day Carryover Cap

Priya works full time in the UK, Monday to Friday, on a 1 January to 31 December leave year.

The entitlement

• Statutory entitlement: 5.6 weeks × 5 days = 28 days
• Regulation 13 portion: 4 × 5 = 20 days
• Regulation 13A portion: 1.6 × 5 = 8 days
• Contractual carryover cap: 5 days, expiring 31 March

Scenario one: an ordinary year

Priya takes 21 days by 31 December.

• Unused balance: 28 − 21 = 7 days
• Her policy consumes Regulation 13 leave first, so those 21 days are all 20 Regulation 13 days plus 1 Regulation 13A day.
• The 7 remaining days are therefore all Regulation 13A leave, with no automatic statutory carryover right.
• Cap applied: 5 days carry forward, 2 days lapse.
• Opening balance on 1 January: 28 + 5 = 33 days, of which 5 expire on 31 March.

Scenario two: six weeks of sickness absence

Now assume Priya was signed off sick from mid-November and finished the year having taken only 16 days, leaving 12 unused.

• Regulation 13 leave used: 16. Unused Regulation 13 leave: 20 − 16 = 4 days.
• Those 4 days carry over as a statutory right and sit outside the 5-day cap.
• The remaining 8 days are Regulation 13A leave, so the cap applies: 5 carry forward, 3 lapse.
• Total carried into the new year: 4 + 5 = 9 days, not 5.

That second calculation is the one manual trackers get wrong, because it requires splitting the balance by regulation rather than treating it as one pot.

What Are the UK Carryover Rules?

UK statutory annual leave is 5.6 weeks per leave year under the Working Time Regulations 1998, equal to 28 days for a five-day worker, and bank holidays may be counted within that figure (GOV.UK). That entitlement is not one block. It splits into two portions with different carryover treatment.

The first four weeks (Regulation 13)

This is the EU-derived portion, intended to be taken in the year it accrues. Workers on long-term sick leave who could not take it may carry over up to four weeks of statutory leave into the next leave year, and that carried leave remains available for a defined period rather than lapsing at the next year end (GOV.UK). Carryover rights also arise where a worker was on maternity or other family leave.

A contractual cap cannot override those rights. If your policy says “maximum five days” and an employee has a statutory right to carry four weeks after long-term sickness, the statute wins.

The additional 1.6 weeks (Regulation 13A)

This portion is a domestic UK addition, and the part most employers fold bank holidays into. It does not carry over automatically. It moves into the next leave year only where the contract or a workplace agreement allows, which is exactly where a carryover cap belongs.

Leave above 5.6 weeks

Anything beyond the statutory 28 days is purely contractual. You decide whether it carries over, how much, and when it expires. Most UK carryover caps sit at three to five days on this contractual layer.

For maternity and employer-failure scenarios in detail, see our guide to carrying over annual leave in the UK, and the UK annual leave entitlement guide for how the 5.6 weeks is built up.

How Does Carryover Treatment Differ by Country?

Carryover caps are not portable. A policy that is lawful in London can be unlawful in Melbourne, because the underlying entitlement behaves differently.

Market	Statutory position on unused annual leave	Can an employer cap carryover?
United Kingdom	5.6 weeks split into 4 weeks (Reg 13) plus 1.6 weeks (Reg 13A). Carryover of statutory leave is required in defined cases such as long-term sickness. (GOV.UK)	Yes on the Reg 13A portion and on leave above 5.6 weeks. No where a statutory carryover right applies.
Australia	Four weeks per year of service, accruing progressively and accumulating year to year. It does not lapse. (Fair Work Ombudsman)	No. Manage large balances through award-based excessive leave provisions instead.
New Zealand	Four weeks of annual holidays after 12 months of continuous employment, available until taken or paid out. (Employment New Zealand)	No. Employers may direct leave during a customary closedown with notice, but cannot delete entitlement.
Germany	24 working days on a six-day week under the Bundesurlaubsgesetz. Leave may carry into the first quarter of the following year where personal or operational reasons prevented it being taken. (Gesetze im Internet)	Limited. Under ECJ case law, statutory leave expires only where the employer actively warned of the balance and the risk of forfeiture.
United States	No federal entitlement to paid annual leave. Treatment is set by state law and contract, and some states treat earned vacation as wages.	Usually, subject to state wage rules. Check your state labor department.

The pattern is worth stating plainly: where leave accrues as an accumulating entitlement, a forfeiting carryover cap is generally unavailable; where leave is a contractual benefit, it generally is. In Australia the compliant equivalent is a direction to take leave once a balance becomes excessive, which we cover in our guide to excessive annual leave balances in Australia.

Carryover Cap vs Accrual Cap

A carryover cap is a year-end event applied to unused leave. An accrual cap is a continuous ceiling on the balance itself, pausing further accrual and resuming it as soon as the employee takes leave.

The practical difference is what happens to earned time. A carryover cap can extinguish leave the employee already earned, which is why statutory protections matter so much. An accrual cap never removes earned leave. If your concern is a growing liability rather than a year-end tidy-up, an accrual cap is usually the safer instrument.

How Do You Write a Carryover Cap Policy That Holds Up?

1. State the cap and the expiry together. “Five days, to be used by 31 March” is a policy. “Five days” alone is a growing balance.
2. Carve out statutory carryover explicitly. Say in writing that leave carried over because of sickness or family leave sits outside the cap.
3. Define the order of use, so the year-end remainder is never ambiguous.
4. Warn people in time. Send balance reminders two to three months before year end, while the calendar still has room.
5. Record every year-end decision: the balance, the carried amount, the lapsed amount, and the reason.

Frequently Asked Questions

Is a leave carryover cap legal?

It depends where your people work and which portion of leave it touches. Caps on contractual leave above the statutory minimum are generally fine. Caps that extinguish statutory entitlement are not, and in Australia and New Zealand accrued annual leave does not lapse at all.

What is a typical carryover cap?

Three to five days is the most common contractual cap for a full-time employee with a 25 to 28 day entitlement, usually expiring at the end of the first quarter. Caps expressed as a percentage of entitlement travel better across part-time working patterns.

Do part-time employees get a smaller carryover cap?

They should. Express the cap in the same unit as the entitlement and pro-rate it. A five-day cap for a full-time worker becomes three days for someone working three days a week. A flat day count advantages part-time staff and confuses payroll.

What happens to carried-over leave when someone leaves?

Accrued but untaken statutory leave is normally paid out on termination. In the UK, workers must be paid for accrued but untaken statutory leave when employment ends (GOV.UK). Whether lapsed or contractual leave is paid out depends on your contract wording, so make it explicit.

Tracking Carryover Without a Spreadsheet

Carryover caps stay simple until you have three countries, two leave years, part-time patterns, and a statutory carve-out for someone who was off sick in November. That is where a year-end spreadsheet reconciliation stops being reliable.

Leave Balance applies carryover caps and expiry dates automatically, keeps statutory and contractual leave in separate buckets, and shows every employee their balance before the leave year closes.
