Decisions / What If My Partner Stops Working?
What If My Partner Stops Working?
If one salary drops to zero, the remaining earner can cross a tax band, keep student loan repayments, and — if you have children — become the higher earner for Child Benefit clawback. HICBC still follows that person’s adjusted net income against the £60,000–£80,000 taper, not both salaries added together. Set the date the income changes and those knock-ons share one UK year loop.
A journey can hold this event and later ones. Two free journeys, 15-year cap. Paid paths run 30 years.
Then The Events That Follow
This question starts the journey. Add later events on the same years so tax, leftover cash, childcare and retirement move together. A calculator answers one slice. Free paths run 15 years; paid unlocks run 30.
How Kumberi Models A Partner Income Change
A Date And A New Figure — Not A Guessed Return
You set when paid work stops or reduces, whose job it is, and the new annual amount. From that date the year loop uses the new employment income. A later return is a second milestone if you add one. The engine does not invent a return-to-work date.
Each Person’s Tax, Not A Blended Rate
Income tax (including Scottish bands when the journey is set to Scotland), National Insurance and student loan plans follow each person’s income. Marriage allowance is not applied as an automatic transfer. Rate tables are in Calculation Methodology. The household cash-flow view is a compiled picture of both people, not a bank feed.
Children Can Flip The Higher-Earner Tests
If Child Benefit is in the journey, the High Income Child Benefit Charge follows the higher earner’s adjusted net income against the £60,000–£80,000 taper — not the sum of both salaries. Funded hours and Tax-Free Childcare also gate on income, including the £100,000 Tax-Free Childcare interaction. A pay drop can restore net Child Benefit or change nursery net cost in the same run. Inspect the tax year rather than assuming the charge disappears in a maternity year.
What A Pay Calculator Misses
A take-home-pay tool shows one person in one year. It will not show HICBC taper, funded hours, or whether later retirement withdrawals have to rise to replace the lost salary. Household cash flow can sketch a typical month; the journey is where those figures sit across years.
Open Household Cash FlowWhat This Page Does Not Model
- Marriage allowance is not modelled as an automatic transfer between spouses.
- Kumberi does not connect to PAYE or banks. You enter current salaries and the change you want to test.
- Childcare and Child Benefit only move if those items are in the journey. An income-only path will not invent children.
Common Questions
Can Kumberi Tell Us Whether One Of Us Should Stop Working?
No. That is a personal decision. The product projects cash flow and UK tax under the change you describe. It does not recommend stopping or continuing paid work.
Does A Lower Salary Always Restore Child Benefit?
Not as a slogan. HICBC follows the higher earner’s adjusted net income against the £60,000–£80,000 taper used in the product. Maternity-year modelling can use pre-leave higher-earner income for Child Benefit — inspect the result. How funded hours and Tax-Free Childcare interact with income is in Funded Childcare.
Can I Model A Return To Work Later?
Yes. Add a later income-change or return-to-work milestone with the new salary and date. The engine does not assume a return unless you add one.
How The Rules Are Documented
These are the Learn pages behind this decision — inspectable methodology, not extra opinion pieces. The full set lives on Learn.
- Funded Childcare15/30 hours, Tax-Free Childcare and the £100,000 gate — all income-sensitive if children are in the journey.
- Student LoansEach earner’s plan keeps calculating after the income-change date.
- Calculation MethodologyIncome tax, NI and Scottish bands used in the year loop.
- Retirement PlanningLost salary years change how workplace pots and State Pension sit later.
- ISA TypesA missing wage can starve leftover cash that would otherwise hit remaining ISA allowance.
Other Decisions
- What If We Have Another Child?Child Benefit, HICBC, funded hours and leave — not only a nursery line in a spreadsheet.
- What If My Pay Changes?A new salary is not take-home times twelve — bands, loans and childcare gates can all move.
- Could We Afford This House?Stamp duty, the deposit and the new mortgage — on the same years as tax and retirement.
