Maternity Leave Carryover Deadline Calculator

Based on the default pattern below, a typical deadline is June 2029. Adjust the inputs for your exact figure.

Carryover deadline

June 2029

How it's worked out

December 2027 leave year end + 18 months = June 2029

Audit note

The 18-month statutory deadline applies to Reg 13 carryover from long-term sickness or family leave specifically, and runs from the END of the leave year it accrued in — not from the date it was accrued. Contractual deadlines can be shorter, but can never override the statutory 18-month floor for protected leave.

Stop tracking this by hand

Carryover only stays accurate if the balance behind it is accurate. Tempry tracks every day of accrued, taken and carried-over leave automatically, so nobody has to work out a carryover cap or a forfeiture deadline by hand again.

How this calculation works

Carried-over leave isn't open-ended — work out the exact month and year it must be used by, whether it's protected sick-leave carryover (18 months) or your employer's own policy deadline.

Worked example

December 2027 leave year end + 18 months = June 2029

Frequently asked questions

When must holiday carried over from maternity leave be used by?
Within 18 months of the end of the leave year it accrued in — the same statutory deadline that applies to long-term sickness and other protected carryover reasons.
Does it matter when during maternity leave I accrued the holiday?
No — the deadline runs from the end of the leave year it accrued in, not from the specific week of maternity leave you were on.
Can my employer set a shorter deadline for maternity carryover?
No — 18 months is the statutory floor for this protected reason; an employer's policy can't shorten it, though it could choose to be more generous.
