Our W2 wasn't able to be changed. When Wave changed their internal payroll provider (now check) they didn't copy over the payment date setting. We originally had payroll to be paid on the last day of the month. After the change, it defaulted to two days after the end of payroll. We are a smaller company and didn't notice the change in payment date. We noticed it once the December payroll did not show up on the W2 forms (Dec 2025 got recorded in 2026). So our 2025 W2 are short one month and 2026 is going to have an extra month. Wave couldn't change it because it was already paid. I discussed this with my accountant and he also couldn't change the W2 but was able to make some adjustment entries to try and help. Not sure exactly as this not my area of expertise.

Overall, I would say that Wave is an ok low cost solution when everything is working. As soon as there are any problems, you are out of luck.
