Start filling →Form Overview
The Assessable Spouse Election Form is used by married couples in Ireland to elect for tax assessment purposes. This form allows couples to specify how their income should be assessed for tax purposes when one spouse has no income or minimal income.
Plain English
If you're married and one of you doesn't earn much or anything at all, this form lets Revenue know how you want your taxes handled. It's a way married couples can potentially reduce their overall tax bill by combining incomes.
Submission Date
| Situation | Likely form | Why it matters | Check before you continue |
|---|---|---|---|
| Separated couples | Form 11 (individual tax return) | Different tax treatment applies when spouses are separated | Check your separation date and terms |
| Civil partners | Same form but marked for civil partnership | Similar tax treatment but different legal basis | Verify civil partnership registration details |
| Divorced individuals | Form 11 (individual tax return) | Joint election no longer applies after divorce | Confirm divorce is legally finalized |
| Unmarried couples | Form 11 (individual tax return) | No joint assessment option for unmarried couples | Ensure relationship status is correctly declared |
The form should be submitted by the end of the tax year in which the marriage occurred or when income circumstances change, but no later than October 31st following the end of the tax year.
