SMP is taxable and subject to National Insurance like normal pay. Your employer reclaims most or all of it from HMRC. You need 26 weeks of continuous employment by the qualifying week (15th week before the due date) and average earnings of at least £125/week (2025/26 Lower Earnings Limit). If you do not qualify for SMP you may qualify for Maternity Allowance from the DWP at the same £187.18 weekly rate. Statutory pay rates uplift every April — check gov.uk/maternity-pay-leave for the current year.

Common questions
- What about paternity, adoption and shared parental pay?
- Statutory Paternity Pay (SPP), Statutory Adoption Pay (SAP) and Shared Parental Pay (ShPP) all pay at the same £187.18 weekly cap. SPP runs for up to 2 weeks. SAP follows the same 6+33 structure as SMP. ShPP allows you to share up to 50 weeks of leave and 37 weeks of pay between parents.
- Do I get pay rises during maternity leave?
- Yes — you must be treated as if you were not on leave for pay rises. If you get a rise in or after the 8-week reference period used for SMP, your SMP must be recalculated.
- Can my employer ask me to come back early?
- No. You can choose to return early but you must give at least 8 weeks' notice. You have the right to return to the same job after the first 26 weeks (Ordinary Maternity Leave); after that, to a similar role with the same terms.
