Do I have to pay the tax before disputing it?

Not in Tax Court - that is its central advantage. A refund suit in district court or the Court of Federal Claims requires full payment first.

What is the deadline to petition?

The period runs from the statutory notice of deficiency and is jurisdictional. The court has no power to extend it, so treat the notice date as absolute.

Is there a simplified procedure?

Yes, a small tax case procedure for disputes under a defined amount, with relaxed rules - but those decisions cannot be appealed.

United States Tax Court - Disputing an IRS Deficiency

United States Tax Court

The United States Tax Court is the only forum where a taxpayer can dispute an IRS deficiency **before paying it**. That is its defining feature: elsewhere you must pay first and sue for a refund. The right to petition arises from a statutory notice of deficiency, and the deadline to file is jurisdictional - the court cannot extend it, whatever the reason.

What it does

Redetermines IRS deficiencies before payment is required
Hears collection due process appeals
Decides innocent spouse relief and worker classification cases
Operates a simplified small tax case procedure

Matters it hears

Income, estate and gift tax deficiencies
Penalty and accuracy-related disputes
Collection due process determinations
Innocent spouse relief claims
Worker classification determinations

Appeals & review

Appeals go to the US Court of Appeals for the circuit where the taxpayer resides, not to the Federal Circuit.

Appeal and review deadlines are short and strictly applied. Treat the decision date as the start of a clock.
