If the adult dependant is your spouse / partner / civil partner, we'll calculate the Adult Dependants Allowance (ADA) using their net taxable income from the last tax year.
If the adult dependant isn't your spouse / partner / civil partner, we'll calculate it using the adult dependant's net income from the current academic year. You can't claim ADA if their income will be more than £3,796 in the current academic year.
