if fraud is involved, is there a limit on the assessment of a deficiency by IRS?

Answer 1

Nope. Normally, IRS has 3 years for assessment, 6 years on gross understatement of income (25% change in tax), and forever on fraud.

Answer 2

There is no statute of limitations on fraud.

If you fail to file due to fraud: 15% for each month or part of a month your return is late pub 17 p19

Accuracy related penalty; 20% of the under payment pub 17 p 19

Fraud; 75% of the amount underpaid because of fraud pub 17 p 20

Failure to file and failure to pay on time; 5% (4.5% failure to file, .5% failure to pay) for each month or part of a month return is late and unpaid. Pub 17 p19

Interest is compounded daily and is currently 8% APR, rate can change quarterly

All this adds up to a lot more than I want to pay

Answer 3

No, there's no statute of limitations if fraud is involved. And if you didn't file but were required to file, the clock doesn't start running until you file.

Answer 4

No, there's no SOL on tax fraud.
