5 Maternity Pay Planning Tips
- Give 28 days' notice: You must tell your employer at least 28 days before you want your SMP to start — and confirm it in writing.
- Understand your full entitlement: You have 52 weeks of maternity leave — the first 26 weeks are Ordinary Maternity Leave and the next 26 are Additional Maternity Leave. SMP only covers up to 39 of these weeks.
- Explore Shared Parental Leave: SPL allows you and your partner to share up to 50 weeks of leave after the compulsory 2-week period — giving families more flexibility.
- Check Maternity Allowance: If you do not qualify for SMP (e.g. you are self-employed or newly employed), you may claim Maternity Allowance from DWP at £184.03/week for up to 39 weeks.
- Use KIT days strategically: Keeping In Touch days (up to 10) let you work without losing SMP for that week — useful for handover meetings or training.

FAQs
Is SMP taxable?
Yes — SMP is treated as earnings and is subject to income tax and National Insurance in the normal way through payroll.
Does SMP affect my pension?
Your employer must continue paying pension contributions during the 39 weeks of SMP if you are auto-enrolled. Contributions are usually based on your normal pensionable pay, not the reduced SMP amount.
What are KIT days?
Keeping In Touch (KIT) days allow you to work up to 10 days during maternity leave without losing your SMP for that week. They must be agreed with your employer.
