Non-resident state return RE syndication

[Cameron Lee Brown]

For 2020 return, we filed an AZ nonresident return to report PAL to be carried forward. For 2021, there was no income/loss to be reported for AZ. If I want to be able to use the 2020 PAL carryforward in a future year where I might have AZ source income, do I have to file an AZ nr return every year to keep carrying forward the limited loss, or is it okay to not file again until there is an income/loss to be reported? I don’t want to lose the PAL (over $10k), but don’t know if it’s necessary to keep filing the same PAL each year until it can be realized or if filing it the one time is sufficient.
