Tax law covers the paperwork that documents income, deductions, disputes, and settlements with the IRS and state tax authorities. Protests, offers in compromise, installment agreement requests, and appeals each have their own forms, supporting documentation, and strict deadlines. Well-prepared tax correspondence is often the difference between a negotiated resolution and an enforcement action with levies, liens, or penalties.
