Maternity Pay: SMP vs Maternity Allowance – The Definitive Guide
1. Overview
Navigating income support during pregnancy and the first year of a child's life is a critical financial challenge. In the UK, there are two primary systems: Statutory Maternity Pay (SMP) and Maternity Allowance (MA).Choosing correctly (or understanding why you qualify for one and not the other) can mean a difference of thousands of pounds. By April 2026, these rates have been adjusted, and their interaction with Universal Credit has become even more central to household budgeting.
This guide breaks down the eligibility, rates, and strategic decisions required to maximise your income during maternity leave.
2. Key 2026 Rules & Rates
Statutory Maternity Pay (SMP)
- First 6 weeks: 90% of your average weekly earnings (no cap).
- Remaining 33 weeks: ~£184.03 per week (or 90% of earnings, whichever is lower).
- Total duration: 39 weeks.
Maternity Allowance (MA)
- All 39 weeks: ~£184.03 per week (or 90% of earnings, whichever is lower).
- The Key Difference: MA does not have the "90% for 6 weeks" bump that SMP offers.
3. Eligibility Criteria
Who gets SMP?
You must be an employee (not a worker or self-employed) and: 1. Have worked for the same employer for at least 26 weeks by the 15th week before the baby is due ("Qualifying Week"). 2. Earn at least £123 per week (average).Who gets Maternity Allowance (MA)?
You qualify for MA if you don't get SMP and: 1. Are self-employed. 2. Started a new job recently (after the qualifying week). 3. Are unemployed but have worked recently. 4. You must have worked for at least 26 weeks in the 66 weeks before the baby is due.4. Financial Impact & Universal Credit Interaction
This is where most claimants lose money.- SMP is treated as earnings: For Universal Credit, SMP is treated like wages. It is subject to the £673 work allowance (if you have children) and the 55% taper.
- MA is treated as "Unearned Income": This is a huge "trap." For Universal Credit, Maternity Allowance is deducted pound-for-pound (£ for £).
- EXPERT INSIGHT: If you are on Universal Credit, you are often financially *worse off* on Maternity Allowance than on SMP, because you lose the benefit of the work allowance and the taper.
5. Step-by-Step Claim Process
For SMP:
1. Tell your employer you are pregnant at least 15 weeks before the due date. 2. Provide your MATB1 form (which you get from your midwife at 20 weeks). 3. Agree on a start date. Your employer pays you through your usual payroll.For MA:
1. Ask your employer for an SMP1 form (explaining why they won't pay you SMP). 2. Apply to the DWP using an MA1 form. 3. Include your MATB1 and test period details.6. Evidence & Documentation Strategy
- The MATB1 is Gold: You cannot get either payment without it. Keep the original safe and only provide copies unless the original is mandated.
- Self-Employed NI: To get the full rate of Maternity Allowance, you must have paid enough Class 2 NI contributions. If you haven't, you might only get the lower rate of ~£27/week. You can often pay "voluntary" Class 2 NI to top this up and unlock the full £184/week.
7. Common Mistakes and How to Avoid Them
1. Missing the 15-week notice: If you don't tell your employer on time, they can delay your SMP. 2. Quitting too early: If you leave your job *before* the qualifying week, you lose SMP. 3. The "Working During Maternity" Trap: You can work up to 10 "Keeping in Touch" (KIT) days without losing your maternity pay. If you work even one hour on an 11th day, you lose your maternity pay for that entire week.8. Advanced Strategy: The "Employment Switch"
If you are planning to change jobs while pregnant, be extremely careful.- If you move jobs after the 15th week before the baby is due, your new employer cannot pay you SMP. You will have to claim Maternity Allowance instead.
- If you stay in your old job until the qualifying week, you lock in your SMP.
9. Interaction with Shared Parental Leave (SPL)
You can "curtail" (end) your maternity leave and pay early to share the remaining weeks with your partner as Shared Parental Pay (ShPP).- Caution: ShPP is paid at the lower rate (~£184). You lose the "90% for 6 weeks" if you switch to SPL too early.
