Quote from KeithOmalley:
Thatâs really incorrect. IF you made say 200k in 2007 then you would have to pay 110% of your tax liability in quartly estimates for the next year not to incur any interest. SO if your tax bill for 2007 was $60,000 then your estimated tax bill for 2008 would be $66,000 total or $16,500 per quarter.
Now suppose in 2008 you made 10 million, your estimated tax payments for each quarter of that year would still be ONLY $16,500. The great thing about this is you can hold all the money in a bank account earning interest until you have to pay your full tax amount by 4/15/09. someone who has a 225,000K payment due in 4 days should know that, this is why I donât believe your story. but i do agree everyone files an extension.
