Sorry, I ran out of time to amend my earlier reponse.
No , she said she was aiming for business profits of £45,000 a year, not her personal income. Those are two very different things.
Her partner’s £25,000 PAYE salary gives him around £21,000 take‑home, or about £1,750 per month, and that includes:
- employer pension contributions
- sick pay
- holiday pay
- maternity/paternity rights
- redundancy protection
- employer NI paid on his behalf
A self‑employed person must self‑fund all of this, so their real disposable income is naturally lower.
Profit is not take‑home pay - She is aiming for £45,000 profit, but profit is not income. If she were employed on £45k, she would take home about £34k.
But as a self‑employed person she gets none of the PAYE protections and must pay for:
- personal pension contributions
- income protection
- life insurance
- critical illness cover (optional)
And crucially: Self‑employed NI does NOT qualify her for contribution‑based benefits. It only counts toward the State Pension. If her partner loses his job through redundancy and becomes ill, his PAYE contributions mean he can access contribution‑based benefits. She cannot. He also gets tax relief at source on pension contributions through PAYE. She does not, she must claim it manually. So her real numbers using her £45,000 profit target:
Item Amount Deductions
Profit £45,000
Income tax −£6,486
NI (Class 2 + 4) −£2,125
Pension (£200/month) −£2,400
Personal insurances −£1,500
_
Estimated balance £32,489
But this assumes:
- she hits the £45k profit target
- she has no bad debts
- clients pay on time
- she doesn’t need to reinvest in the business
- she doesn’t need to retain cash for next year’s expenses
In reality, a self‑employed person must keep money in the business to survive quiet periods and growth phases. So the realistic disposable income is:
£25-29,000pa. And unlike her partner’s income, none of this is guaranteed.
She also likely works longer hours, including unpaid admin, marketing, and downtime. Neither of them are rich.
If they have a tenants in common mortgage and each contributed different deposits, then:
- each should retain their original deposit share
- the remaining equity should be split 50/50
- therefore each should pay 50% of the monthly mortgage
If she pays more than 50%, she is effectively increasing his equity share, which is not fair unless legally agreed.
Any other arrangement should have been discussed and recorded when the mortgage was taken out. If they marry later, they can revise the agreement.
