A client assumes audit support came with their return, gets an IRS notice, and expects you to handle it for free. An engagement letter is what settles\u00a0that,its\u00a0a written record of what you agreed to do, so you can point to the terms you both accepted.<\/span>\u00a0<\/span><\/p>

The stakes are real. Of the claims filed in 2023 against firms in the AICPA Professional Liability Insurance Program,\u00a0roughly 75%\u00a0came from tax services, and more than half of those had no engagement letter on file (<\/span>The Tax Adviser<\/span><\/a>, citing CNA).<\/span>\u00a0<\/span><\/p>

Here is what a tax preparation engagement letter should\u00a0contain, the clauses that hold up when a client pushes back, a free template you can adapt, and a checklist for getting every letter signed before intake opens.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

What Is a Tax Preparation Engagement Letter? <\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

A tax preparation engagement letter is a written agreement between a tax preparer and a client that sets out the returns you will prepare, the fee, the information the client must supply, and the point at which your responsibility ends.<\/span>\u00a0<\/span><\/p>

The letter names the tax year and the specific returns in scope, so “do my taxes” does not quietly expand into bookkeeping, planning, or audit\u00a0defense. For the client, it confirms what they are paying for and what they\u00a0have to\u00a0hand over to keep the work moving.<\/span>\u00a0<\/span><\/p>

A signed letter can act as a binding contract, and it records what you agreed to do, which matters when the IRS examines a return and the client asks why a position was taken.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

A tax preparation engagement letter fixes the scope of work in writing. When a client asks for something outside it, you have a document to point to rather than an awkward conversation to improvise.<\/span>\u00a0<\/span><\/p>

It settles money before money becomes a dispute. Flat fee or hourly, what the out-of-scope rate is, when payment is due, whether the return gets filed before or after you are paid.<\/span>\u00a0<\/span><\/p>

In short, a tax preparation engagement letter helps your firm:<\/span>\u00a0<\/span><\/p>

  • Define the exact returns and schedules covered, so “tax prep” is not left to interpretation<\/span>\u00a0<\/span><\/li><\/ul>
    • Contain\u00a0scope creep, because work you did not name is work you did not agree to do<\/span>\u00a0<\/span><\/li><\/ul>
      • Set out client responsibilities, including complete records delivered on time<\/span>\u00a0<\/span><\/li><\/ul>
        • Fix payment terms, including due dates and the rate for anything extra<\/span>\u00a0<\/span><\/li><\/ul>
          • Document the limits of your responsibility for a professional liability claim<\/span>\u00a0<\/span><\/li><\/ul>
            • Standardize onboarding, so every client starts the season the same way<\/span>\u00a0<\/span><\/li><\/ul>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

              A good tax preparation engagement letter covers what it needs to without\u00a0running\u00a0long, and\u00a0stays clear enough that the client\u00a0actually reads\u00a0it. It should settle four things. Which returns you will prepare, which you will not, what the client\u00a0has to\u00a0give you, and how the work moves from signed letter to filed return.<\/span>\u00a0<\/span><\/p>

              These are the sections every tax preparation engagement letter should carry.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

              Name who the agreement is between and when it takes effect.<\/span>\u00a0<\/span><\/p>

              This usually covers:<\/span>\u00a0<\/span><\/p>

              • The name of the tax firm or preparer<\/span>\u00a0<\/span><\/li><\/ul>
                • The client’s name, and both names if the return is joint<\/span>\u00a0<\/span><\/li><\/ul>
                  • The client’s business or entity name, where relevant<\/span>\u00a0<\/span><\/li><\/ul>
                    • The tax year the engagement covers<\/span>\u00a0<\/span><\/li><\/ul>
                      • The effective date<\/span>\u00a0<\/span><\/li><\/ul>

                        Where the client files through an entity, use the correct legal name. It removes any doubt over who owes the fee and who\u00a0is authorized to\u00a0approve the return. On a joint return, both spouses are the client, and both sign.<\/span>\u00a0<\/span><\/p>

                        For\u00a0example,<\/span><\/b>“This\u00a0letter confirms the terms under which [Firm] will prepare the 2025 federal and state income tax returns for [Client].”<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

                        \n\t\t\t\t
                        \n\t\t\t\t\t

                        Scope of Tax Services <\/h3>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
                        \n\t\t\t\t
                        \n\t\t\t\t\t\t\t\t\t

                        Scope is the most important section in the\u00a0letter, because\u00a0it defines the work everything else depends on. It\u00a0states\u00a0exactly which returns you will prepare and for which year.<\/span>\u00a0<\/span><\/p>

                        Be specific about this. If you only write “tax preparation,” the client is free to assume it covers every form and situation they have, and they usually will. List the exact returns instead.<\/span>\u00a0<\/span><\/p>

                        For\u00a0example,<\/span><\/b>preparation\u00a0of the federal Form 1040 and the schedules that apply, one resident-state return, and a review of the prior-year return for\u00a0carryforward\u00a0items. If the client has rental property, a K-1, or a second state, name those or price them separately.<\/span>\u00a0<\/span><\/p>

                        Name the specific tax year and cover only that year. This keeps the engagement from rolling forward into future returns you never agreed to prepare, and it sets a clear limit on the due diligence Circular 230 Section 10.22\u00a0requires of\u00a0you. Say when your work ends too, either when you hand the finished return to the client to file, or when you file it on their authorization.<\/span>\u00a0<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

                        \n\t\t\t\t
                        \n\t\t\t\t\t

                        Services Not Included <\/h3>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
                        \n\t\t\t\t
                        \n\t\t\t\t\t\t\t\t\t

                        Listing what you will do only draws half the line. The other half is\u00a0stating\u00a0what you will not do, and that half is where most arguments begin.<\/span>\u00a0<\/span><\/p>

                        Clients tend to lump preparation, planning, bookkeeping, and IRS representation together as one service. Unless you say otherwise, they will expect all of it for the fee they paid.\u00a0So\u00a0name the common exclusions plainly<\/span>\u00a0<\/span><\/p>

                        Of all these exclusions, audit and notice handling is the one to be most explicit about. If the IRS examines the return or sends a notice after filing, that is a new engagement with its own letter and its own fee. Make that clear in advance, not once the notice has already landed on the client’s desk.<\/span>\u00a0<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

                        A return depends on what the client gives you. The responsibilities section makes that dependency explicit.<\/span>\u00a0<\/span><\/p>

                        The client is typically responsible for:<\/span>\u00a0<\/span><\/p>

                        • Providing complete and\u00a0accurate\u00a0records<\/span>\u00a0<\/span><\/li><\/ul>
                          • Delivering W-2s, 1099s, K-1s, receipts, and basis information<\/span>\u00a0<\/span><\/li><\/ul>
                            • Disclosing all income, including foreign accounts and foreign income<\/span>\u00a0<\/span><\/li><\/ul>
                              • Responding to questions promptly<\/span>\u00a0<\/span><\/li><\/ul>
                                • Reviewing the return before it is filed<\/span>\u00a0<\/span><\/li><\/ul>
                                  • Signing Form 8879 to authorize electronic filing, and approving any extension<\/span>\u00a0<\/span><\/li><\/ul>

                                    One point\u00a0matters most here. You prepare the return from what the client gives you. You do not audit or verify it independently. Circular 230 lets you rely in good faith on their information, but you must ask questions when something looks wrong or incomplete. The letter should\u00a0state\u00a0that you rely on what they provide and will follow up when something does not add up.<\/span>\u00a0<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

                                    \n\t\t\t\t
                                    \n\t\t\t\t\t

                                    Fees & Payment Terms <\/h3>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
                                    \n\t\t\t\t
                                    \n\t\t\t\t\t\t\t\t\t

                                    If the fee is unclear now, it becomes a payment dispute later. State the fee plainly.<\/span>\u00a0<\/span><\/p>

                                    • Flat fee, hourly rate, or a base fee plus hourly for complications<\/span>\u00a0<\/span><\/li><\/ul>
                                      • Any minimum or deposit due before work begins<\/span>\u00a0<\/span><\/li><\/ul>
                                        • The rate for out-of-scope work<\/span>\u00a0<\/span><\/li><\/ul>
                                          • When payment is due<\/span>\u00a0<\/span><\/li><\/ul>
                                            • Late-payment terms<\/span>\u00a0<\/span><\/li><\/ul>

                                              If you charge a flat fee, say what it covers, which return, which schedules, one state. If added work is billed hourly,\u00a0state\u00a0the rate and when it kicks in. A common and defensible approach is to require written approval before any out-of-scope work starts.<\/span>\u00a0<\/span><\/p>

                                              Many firms hold filing until the fee is paid. If that is your policy, put it in writing, so the return will not be e-filed until the invoice is settled.<\/span>\u00a0<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

                                              Tax work runs on a hard calendar, and the letter should run on it too.<\/span>\u00a0<\/span><\/p>

                                              Set the filing deadline and, critically, the date by which you need complete information to hit it. If the documents arrive after that cutoff, the letter should say in advance that an extension may be necessary.<\/span>\u00a0<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

                                              An<\/span>\u00a0extension only gives the client more time to file the return. It does not give them more time to pay. Any tax owed is still due by the original deadline, and anything unpaid after that keeps building penalties and interest. Make sure the client understands this, so they do not treat an extension as extra time to pay.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

                                              Tax preparers handle some of the most sensitive data a client has. The letter should address how you protect it.<\/span>\u00a0<\/span><\/p>

                                                      Set the exit terms before you need them. Without them, a client can walk away mid-engagement and then argue over the fee for work you already did.<\/span>\u00a0<\/span><\/p>

                                                      Cover four things. How either side ends the engagement, how much notice is needed, how the final bill is settled, and how records are returned. One rule to know here is that Circular 230 Section 10.28 requires you to return the client’s own records promptly when they ask, even during a fee dispute. You may keep copies, and you may hold back work you prepared yourself where the rules allow it.<\/span>\u00a0<\/span><\/p>

                                                      For example,<\/span><\/b>\u00a0either party may end the engagement with 30 days’ written notice, the client pays for all work completed up to that date, and their records are returned promptly.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

                                                      This section sets the outer edge of your responsibility, and because it carries legal consequences, an attorney should review it before you use it.<\/span>\u00a0<\/span><\/p>

                                                      Broadly, it can clarify that you are not responsible for errors that trace to incomplete, inaccurate, or late information from the client, and that positions on the return rest on what the client represented. It can also confirm that decisions about the client’s tax positions and business affairs\u00a0remain\u00a0the\u00a0client’s.<\/span>\u00a0<\/span><\/p>

If those figures are wrong, the resulting return is not your liability.
