Tax Penalty Deduction

[faugust]

My client incurred and paid a tax penalty due to an error I made on his tax return.   I am reimbursing my client for penalty he paid and am questioning whether I can deduct client reimbursement on my Schedule C as a reimbursement expense.

Yes it is deductible.  I would put it under "returns and allowances."
