Calculate IRS penalty

[holtaboy]

Guys - I I had filed an extension request back in April and I just did my order as filing but I owe 20,000. Is it 0.5% every month for penalty and 5% interest? Are these calculations approximately correct?

Penalty - $100 every month of filing late

Interest - $500 total interest for 6 months late

Thanks

The penalty for failing to file on time is 5% per month (or part of month) then 0.5% per month after.  That would not apply to you if you have an extension.

The penalty for late payment is 0.5% per month or part of month.  So if you pay 1 day late or 29 days late, 0.5%.  If you pay between 31 and 60 days late, 1%.  And so on.

Then, the entire balance (interest plus penalties) is assessed interest which is a variable rate and I think is currently 8% APR.  

So on a debt of $20,000 for 6 months, penalty and interest should be around $1400, using this calculator.
