taxmap/pubs/p225-070.htm#en_us_publink1000218906If you do not pay all your required estimated tax for 2010 by
January 18, 2011, or file your 2010 return and pay the tax by March 1, 2011, you
should use Form 2210-F, Underpayment of Estimated Tax by Farmers and Fishermen,
to determine if you owe a penalty. If you owe a penalty but do not file Form
2210-F with your return and pay the penalty, you will get a notice from the IRS.
You should pay the penalty as instructed by the notice.
If you file your return by April 18, 2011, and pay the bill within
21 calendar days (10 business days if the bill is $100,000 or more) after the
notice date, the IRS will not charge you interest on the penalty.
 | Do not ignore a penalty notice, even if you think it is in
error. You may get a penalty notice even though you filed your return on time,
attached Form 2210-F, and met the gross-income-from-farming requirement. If you
receive a penalty notice for underpaying estimated tax and you think it is in
error, write to the address on the notice and explain why you think the notice
is in error. Include a computation similar to the one in Example 1 (earlier),
showing that you met the gross income from farming requirement. |
