No state return required in Florida. But every W-2, 1099, and K-1 issued to you is also reported to the IRS. When you don't file, the IRS eventually files a Substitute for Return with zero deductions and the worst filing status. The balance is usually inflated.
File your own returns, even years late. They replace the SFRs and often reduce the balance. IRS policy generally looks for the last six years of returns before it will agree to a payment plan or other resolution.
If you have unfiled returns, let me help you get compliant safely.
