You need actual tax software or would a spreadsheet like LibreCalc work?
I keep the books for our company, and do my own payroll, so yes, needs to be tax software
Let me know if any of these 14 work for you: https://itsfoss.com/open-source-accounting-software/ Tax software, can use opentaxsolver, or wine/vm for windows stuff, https://opensource.com/article/21/2/linux-tax-software
