The BIG Guide to Having a Baby (When You Run a Business)

There is a lot of “you’ve got this mama” content online. Which is lovely & emotionally supportive.

And completely useless when you are trying to work out what is happening to your income, your tax and your business.

Sole Trader vs Limited Company: start here

If you only read one section, read this.

Because your business structure affects:

• what pay you can get

• how your cashflow behaves

• what admin you are dealing with

• and how painful HMRC becomes at the worst possible moment

Sole trader

Simple. Less admin. Less paperwork. No payroll. Sounds ideal, until HMRC turns up.

If you are self-employed, you are usually looking at Maternity Allowance.

That is:

• up to £194.32 per week (2026/27)

• for up to 39 weeks

• tax-free

Which is helpful, but not life-changing.

Then there is the bit nobody warns you about: payments on account

If you had a good year before the baby, HMRC may ask for:

• last year’s tax

• plus next year’s tax in advance

At the exact moment your income drops.

Limited company

More structure. More admin. More cost, but more options.

If you are on payroll properly, you may qualify for Statutory Maternity Pay (SMP).

That gives you:

• 6 weeks at 90% of your salary

• then £194.32 per week for 33 weeks

And your company can reclaim most of it from HMRC.

Sounds great.

But only if:

• you were on payroll early enough

• your salary was high enough

• and everything is set up properly

You cannot panic incorporate halfway through pregnancy and expect it to work.

Timing matters.

The honest answer

There is no perfect structure.

• Sole trader = simpler, but cashflow can bite

• Limited company = more options, but more hassle

This is not about what is “best”.

It is about what works for your life with a baby.

What pay can you actually get?

Let’s strip this back.

If you are self-employed

You are looking at:

Maternity Allowance

• up to £194.32 per week

• up to 39 weeks

• depends on NI contributions

No standard paternity pay.

No adoption equivalent.

Just the basics.

If you run a limited company

If set up correctly:

Statutory Maternity Pay

• 6 weeks at 90% salary

• then £194.32 per week

• paid through payroll

Statutory Paternity Pay

• £194.32 per week

• usually up to 2 weeks

Adoption Pay

• same structure as maternity pay

But again:

only if everything is set up properly in advance.

Getting pregnant: structure decisions

This is where people get it wrong.

They think:

“I’ll just switch to a limited company now.”

Sometimes that works.

Often it is too late.

Before pregnancy (ideal world)

• structure properly

• set up payroll

• plan salary

• build cash reserves

During pregnancy

• work with what you have

• focus on cashflow

• avoid last-minute structure changes

After the baby

This is often the best time to review:

• how much you want to work

• whether income will change

• whether you want simpler admin

• or more flexibility

Sometimes the answer changes after the baby arrives.

That is normal.

Childcare: the bit that actually costs money

This is where reality kicks in.

Childcare is expensive.

And the government support is helpful…

…but not quite as generous as it sounds.

“30 hours free childcare”

Let’s translate this properly.

• usually term-time only (38 weeks)

• starts the term after your child reaches the eligible age

• not always actually free (extras get charged)

It helps.

It does not cover full-time childcare.

UK differences (very important)

Support is different depending on where you live:

• England: 30 funded hours (expanding from 9 months+)

• Scotland: 1,140 hours per year (roughly 30 hours)

• Wales: 30 hours including holiday support

• Northern Ireland: much more limited

Tax-Free Childcare

This is one of the better schemes.

• government adds £2 for every £8 you pay

• up to £2,000 per year per child

It helps reduce costs.

It does not eliminate them.

Universal Credit childcare

• can cover up to 85% of costs

• but often reimbursed after you pay

Which can be awkward for cashflow.

Can I claim childcare as a business expense?

Short answer:

No.

Does not matter if you are:

• self-employed

• a limited company

• hiring a nanny

Childcare is a personal cost.

Not a business expense.

Paying grandparents (and a useful trick)

If grandparents help with childcare:

They usually cannot just be “paid” through the business.

But there is something useful:

Specified Adult Childcare Credits

This allows:

• parents to transfer NI credits

• to grandparents helping with childcare

Which helps protect their State Pension.

Very underused.

Very useful.

What actually matters (accounting version)

When planning for a baby as a freelancer, focus on:

• what income is continuing

• what income is stopping

• what support you qualify for

• what childcare will realistically cost

• what HMRC will still expect from you

Final thought

Having a baby can be overwhelming.

It can also make things very clear very quickly.

What matters. What does not.

And what needs sorting financially.

You do not need a perfect plan. But you do need a realistic one.

Because while babies are unpredictable…

HMRC deadlines are not.
