How much of an IRA is deductible ?

[KenH1]

For 2016, the maximum IRA contribution is $5500 ($6500 if you were over 50)

You can always contribute to a traditional IRA, regardless of your income or coverage by an employer plan.

The deductibility depends on your income, filing status, and employer coverage.
