Trying to understand the ACA income reporting procedure

10. Q about "income"

My wife and I are considering retiring next year - ages 61 and 62 - and living off of money we have set aside in an annuity.
The annuity is post-tax and we have paid taxes on its earned interest over the years.

Will this money be considered "income" for the purpose of receiving help in paying for our insurance. I called the 800 number but they were unable to give me an answer.

On edit:
The link above to MAGI does mention annuities, but I know that some annuities are pre-tax and therefore are income when you draw from them. Ours is not. We paid income tax on the money in the annuity and on the interest earned and so its basically a savings account.
