Self-Employed and Independent Contractor Tax Debt
Why balances build differently without withholding, and which penalty catches it.
The thing most worth knowing
The penalty that catches self-employment is not the one most people expect. The IRS frames the rule as "Taxes are pay-as-you-go" — you pay during the year, through withholding or through quarterly estimated payments. Without an employer withholding, the estimated tax penalty is the mechanism that applies, and it is the ONE penalty on this site that reasonable cause does not reach and that First Time Abate does not remove.

Questions this raises
When are estimated payments due?
The IRS publishes them as April 15 for income earned January 1 to March 31, June 15 for April 1 to May 31, September 15 for June 1 to August 31, and January 15 of the following year for September 1 to December 31.
Can the estimated tax penalty be removed?
Not by the two routes that reach most penalties. The IRS states "Reasonable cause doesn't apply to certain penalties such as the estimated tax penalty", and the estimated tax penalty is not among the penalties First Time Abate or the Automatic Exemption from Penalty remove. It is also excepted from the compliance test for that relief, so an estimated tax penalty in the prior three years does not spoil the record.
What does the IRS ask for if I have self-employment income?
Form 433-F asks, where you or your spouse have self-employment income, for the business name, its EIN, the type of business, and the number of employees not counting the owner. The IRS chooses which Collection Information Statement it wants; the notice or the IRS employee names the form.
