Married in community of property: how your tax is split
If you are married in community of property, SARS taxes each spouse on half of the couple's investment income, regardless of whose name the asset or account is in. Interest, dividends, rental income, and capital gains from the joint estate are split 50/50: you are taxed on half of your own and half of your spouse's. Income you earn from working, such as a salary, is not split. It stays with the spouse who earned it.
This catches people out in both directions. A spouse who holds the family's investments in their sole name is taxed on only half of the income from them. A spouse who thought they had no investment income finds half of the other's interest landing on their return.
What is split, and what is not
The dividing line is the source of the income. The joint estate owns the couple's assets, so the income those assets produce is shared. Income from personal effort belongs to the person who earned it.
Split 50/50 between the spouses:
- interest from bank accounts and investments
- dividends
- rental income from let property
- capital gains (and capital losses) on the joint estate's assets
Not split, taxed in the hands of the spouse who earned it:
- salary, wages, and other remuneration from a trade or employment
- pension, provident fund, and retirement annuity income
- income from a business carried on by one spouse
How you declare it matters. For investment income, rental income, and capital gains, each spouse captures the full amount on their own return, and SARS divides it 50/50 automatically when it assesses. You do not pre-halve the figures yourself. SARS can also confirm your marital status with Home Affairs and replicate an interest certificate across both returns.
Why the split can lower the total tax
Splitting income across two taxpayers can reduce the household's total tax, because each spouse has their own brackets, their own rebate, and their own annual exclusions and exemptions. The clearest case is capital gains tax, where each spouse gets a full annual exclusion.
A worked example: a capital gain
One spouse sells a share portfolio held for several years and makes a capital gain of R100,000. The shares were part of the joint estate, so the gain is split 50/50. Neither spouse has any other capital gain in the year.
Each spouse is treated as making a R50,000 capital gain. Each applies their own annual exclusion of R40,000 (2026 year of assessment):
- Spouse A: R50,000 less R40,000 exclusion = R10,000, included at 40% = R4,000 added to taxable income
- Spouse B: R50,000 less R40,000 exclusion = R10,000, included at 40% = R4,000 added to taxable income
- Total included across the couple: R8,000
Compare that with the same R100,000 gain accruing to one person alone, with one annual exclusion: R100,000 less R40,000 = R60,000, included at 40% = R24,000. The community-of-property split brings the included amount down from R24,000 to R8,000, because two annual exclusions apply instead of one. The actual tax each spouse pays then depends on their own marginal rate.
Interest works on the same principle. R50,000 of interest from an account in one spouse's name is taxed as R25,000 in each spouse's hands, and each spouse can apply their own annual interest exemption to their half. Confirm the current interest exemption amount with SARS before relying on a specific figure.
Frequently asked questions
How is investment income taxed if I am married in community of property?
Interest, dividends, rental income, and capital gains from the joint estate are split 50/50, so each spouse is taxed on half of their own and half of the other spouse's investment income, no matter whose name the asset is in. You each declare the full amount and SARS splits it automatically on assessment.
Does the 50/50 split apply to my salary?
No. Salary, wages, and other income earned from a trade or employment are not split. They are taxed in the hands of the spouse who earned them. The same applies to pension, provident, and retirement annuity income, which stays with the member.
Do I declare half or the full amount on my return?
You declare the full amount on your own return. SARS divides interest, rental income, and capital gains 50/50 between the spouses when it processes the assessments. Halving the figures yourself before you file leads to the income being understated once SARS applies the split.
Does being married in community of property save tax?
Often, yes, on investment income. Because each spouse has their own brackets, rebate, and annual exclusions, splitting a capital gain or interest across two returns can use two annual exclusions instead of one and keep more of the income in lower brackets. It makes no difference to income that is not split, such as a single salary.
What about a capital loss?
A capital loss on a joint-estate asset is split 50/50 as well, so half goes to each spouse's CGT calculation. Each spouse sets their half against their own capital gains for the year or carries it forward under the normal rules.
Declare in full and let SARS split it
Knowing what splits and what does not lets you declare correctly and see where two sets of exclusions help. Our guide to tax on rental income covers how a let property's profit is worked out before it is divided between spouses, and the income tax calculator shows how each spouse's half lands in their own brackets.
