Married vs Single in Retirement
The Tax Differences That Could Save You Thousands
If you're married or in a civil partnership, you have access to pension tax planning strategies that simply don't exist for single people. Used properly, these can save thousands of pounds in income tax every year throughout retirement.
The Double Personal Allowance Advantage
Every UK taxpayer has a personal allowance — currently £12,570 — meaning the first £12,570 of income each year is completely tax-free. As a couple, you have a combined allowance of £25,140.
The key is making sure both allowances are used. If one partner draws all the pension income and the other earns nothing, £12,570 of allowance is wasted every year.
Example: £60,000 Annual Income
| Scenario | Taxable Income | Tax Paid | Net Income |
|---|---|---|---|
| Single person, £60k | £47,430 | ~£11,486 | £48,514 |
| Couple, £30k each | £17,430 each | ~£3,486 each | £53,028 |
Potential annual saving: ~£4,514
Based on 2025/26 rates. Assumes both are drawing pension income. Actual savings depend on individual circumstances.
Income Splitting: The Core Strategy
The goal is to equalise income between partners so both stay in the basic rate band (or lower). This means neither person's income exceeds £50,270, avoiding the 40% higher rate band.
If one partner has a much larger pension pot, they can still split income by drawing less and the other partner drawing more from their own pot, or by using the pro-rata distribution method to balance withdrawals.
Marriage Allowance: £252 Free Every Year
If one partner's income is below £12,570 (not using their full personal allowance), they can transfer £1,260 of their unused allowance to the other partner. This saves up to £252/year in tax. It's not huge, but it's free money that requires a one-time HMRC claim.
When Marriage Allowance Applies
- • One partner earns below £12,570 (not using full allowance)
- • The other partner is a basic rate taxpayer (income £12,571–£50,270)
- • You're married or in a civil partnership
Different Ages: A Hidden Opportunity
If partners are different ages, pension access dates will differ. In the years before the younger partner can access their pension, you may rely heavily on one pot. Plan for this:
- Take higher withdrawals from the accessible pot during the bridging years
- Once both can access pensions, rebalance to split income evenly
- Consider state pension ages — they may also differ
The Personal Allowance Taper Trap
Be aware that the personal allowance is tapered away for incomes above £100,000 — losing £1 of allowance for every £2 of income. If one partner's pension income approaches £100,000, it becomes very important to split income between partners rather than let one person face an effective 60% marginal tax rate in that band.
What Single People Can Do Instead
If you're single, the equivalent strategies are:
- Maximise your own personal allowance usage each year
- Stay within basic rate band where possible
- Use ISA savings to supplement income in high-tax years
- Time state pension deferral to avoid tax bands
