I too used these Sign Here tabs (by RediTab) for a zillion years. Also had a note to remove. Last year I gave them up and spent $0.85 to buy a yellow highlighter. Now I highlight the taxpayer and spouse signature and date field and it's been a life-changer. I may even splurge and buy a 2nd highlighter.

Together we can sell cases of these tabs in stock.

Add to that I just reprinted 1,000 envelopes to the state for property tax returns (still not available yet) but I see they changed addresses. I have for sale cheap two unopened boxes of envelopes. Some people say to put stickers on top of the old address but that looks tacky.
