HSA Contributions w/o Insurance?

[k_coley]

Are HSA contributions tax deductible if you no longer have the insurance coverage originally linked to it? 

Secondly, if I want to close/cash out my HSA account with a small (few dollars) balance, how will that affect my taxes?

While you can use the funds in an HSA at any time to pay for qualified medical expenses, you may contribute to an HSA only if you have a High Deductible Health Plan (HDHP). Since you no longer are enrolled in an HDHP you are not eligible to make contributions to your HSA, but you may request withdrawals for qualified medical expenses.

HSA funds can be spent to cover out-of-pocket healthcare expenses for you and your family. So long as the money is used for qualified expenses, An HSA withdrawal ( HSA distribution ) is not taxed or penalized.

The balance of my HSA funds is within HSA Bank, and I have a debit card for that balance. What should I do if/when that balance reaches $0? 

Close the account (tax implications if i do so/will it affect my credit score closing an account like this)?

Hold on to it if/when I get on another insurance plan and link them?

Currently, HSA Bank gives me the option to fund the cash-only account, so if I contribute to it without a HDHP, what are the specific implications?
