“I am self-employed and expecting a baby. Which income will determine my maternity allowance, and what do I need to do to receive it?”
The firm's answer
An initial calculation, followed by an assessment-based adjustment
“Advance-payment income bases are important for the initial payment, but do not necessarily settle the calculation. Once National Insurance receives the income tax assessment, it reviews the maternity allowance base under the applicable rules.”
How is it calculated for a self-employed woman?
First stage: Income underlying the advances for the three months before stopping work is compared with the previous year's assessment, if available, and the higher base is used. Without a previous assessment, the initial calculation uses the advances alone.
Second stage: Once the assessment for the year work stopped is received, that year's base is compared with the previous year's, using the higher one. This means the relevant income under National Insurance rules, not sales turnover.
National Insurance calculation rules ↗The expected birth date alone does not determine the comparison years. Stopping in December 2026 may have a different effect from stopping in January 2027. National Insurance identifies special base-month rules for January and February births, so the comparison is not automatically always 2027 versus 2026.
Must you wait for the annual return to receive payment?
The initial payment does not wait for the final assessment. The 2027 return is filed after year-end and the assessment is received later. An adjustment is not guaranteed at any particular point in 2028. Reconciliation can result in an additional payment or a debt; review any notice with the firm against your records.
What should you check before giving birth?
- Registration and payments: Eligibility as a self-employed woman requires checking that you were registered as self-employed with National Insurance during pregnancy and paid insurance contributions before stopping work.
- Qualifying period: The benefit period depends on your insurance history. If you are also an employee, each route requires a separate review.
- Up-to-date information: Review advances, assessments and the work-stopping date with the firm. Raising advance payments alone does not guarantee a higher benefit.
- Stopping work: Do not assume you can continue working as usual during the benefit period. Business preservation and maintenance activities may be allowed subject to National Insurance approval.
How is payment received?
A self-employed woman giving birth in hospital generally receives an automatic payment after the birth information is transferred, subject to eligibility. Payment goes to the child allowance account or, for a first birth, the account supplied at the hospital. Maternity allowance is paid in one payment, subject to statutory deductions.
Where a claim is required, or for a home birth or birth abroad, follow the instructions and attach the appropriate documents. If payment has not arrived, check your personal account and contact National Insurance. Filing more than 12 months after stopping work may affect eligibility.
