Lots of misinformation here.
1. The SOL doesn't start until you file the return. IRS is collecting on a Service Filed Return (SFR) which gives you the highest possible tax liability. get the returns filed and you would be surprised how much the amount owed can come down.
2. The AUDIT SOL is 3 years from the later of the due date or the filing date of the return, not ten. The SOL for COLLECTION is 10 years from assessment, but only on an actually filed return. SFR's don't count (see #1 above). payments do not extend this SOL, so even if you make a payment in year 9, day 364. the SOL expires the next day.
3. NASCAR - there is no way nonfiling can be tax evasion because one of the elements of the crime of tax evasion is a statement that is made to impede the collection of the correct amount of tax. Nonfiling is NOT a statement - it is silence, and silence cannot be construed as evasion.
4. The 3 year SOL for payment of a tax liability is Statutory and it is enforced to encourage prompt filing of tax returns. After all, whose fault is it that you didn't even file a return to get the refunds? IRS fault? No, the taxpayer's.
