How Much Does a Tax Attorney Cost?

Tax attorney fees typically range from $3,000 to $10,000 for most IRS resolution cases, though complex matters (criminal defense, large business cases, Tax Court litigation) can cost significantly more. The fee depends on what needs to be done: a simple installment agreement costs less than an Offer in Compromise, which costs less than a Tax Court petition.

When It Pays for Itself

If you owe $80,000 and an attorney negotiates an OIC for $15,000, the $5,000 attorney fee saved you $60,000. If an attorney gets $20,000 in penalties abated, the fee paid for itself four times over. The math often works, but not always — and an honest attorney will tell you when it doesn't.

Beware of firms that charge $10,000+ upfront for "investigation" before they even know what resolution to pursue. That's a red flag.
