History of taxes not filed on time, but never need to pay taxes, only refunds; How to show progress towards always filing taxes

For reasons beyond the scope of this post, I have had periods of 2-3 years of unfiled taxes, filed before the 3 year deadline.

Went through a SF-86P which made me discover that this is an issue (again, no debt not being paid for years, only refunds). Not surprisingly that was denied.

What is others advise to when I get offered another tentative govt. job offer, I can demonstrate I won’t be repeating the past, beyond a year or few of on time filings? Surely the past can easily be used as an example of the futrue, in the eyes of those who adjudicate approvals, no?
