SRCOP transfer (€9,000) in 2026

Under joint assessment, one spouse may be able to use part of the other spouse’s unused standard rate band. The practical impact is that some income can be taxed at 20% instead of 40%, depending on how much band is unused and how the household income is split.

It tends to matter most when one spouse has low or zero income and the other spouse has income above the standard rate cut-off. In two-income households where both spouses already use most of their own 20% bands, the transfer may not change the result much.

Enter both salaries and compare the Net Household Income across Joint, Separate and Single. If the joint option wins, reduce the second salary toward zero and watch whether the gap widens. This is a quick way to see if unused band is the driver.
