Yes, bookkeepers can do taxes, but their authority is narrower than a CPA’s or an Enrolled Agent’s. A bookkeeper who prepares any federal return for pay must register with the IRS and obtain a Preparer Tax Identification Number (PTIN), and even then the IRS classifies them as an “unenrolled preparer” with limited rights to represent you if problems arise. For routine compliance work and straightforward returns, that is often enough. For strategic tax planning or a dispute that escalates past an initial audit, it is not.
What Tax Work a Bookkeeper Can Handle
Most of the tax work a small business needs during the year is recurring compliance, and bookkeepers routinely manage it. Payroll tax filings are a common example. Form 941 is filed quarterly to report wages paid, federal income tax withheld, and both the employer and employee shares of Social Security and Medicare taxes.1Internal Revenue Service. Instructions for Form 941 (Rev. March 2026) Form 940, filed annually, covers federal unemployment (FUTA) tax.2Internal Revenue Service. 2025 Instructions for Form 940
In states with a sales tax, bookkeepers calculate taxable sales for each period and prepare the returns needed to remit those funds, typically monthly or quarterly. They also handle information reporting. Businesses that pay independent contractors must issue Form 1099-NEC, and starting in tax year 2026, the reporting threshold for nonemployee compensation rises from $600 to $2,000 per payee, with future inflation adjustments beginning in 2027.3Internal Revenue Service. 2026 Publication 1099 General Instructions for Certain Information Returns A bookkeeper who tracks contractor payments through the year is well-placed to identify which payees cross the threshold and file on time.
If your business files 10 or more information returns in a year, they must be filed electronically. That threshold took effect for returns filed on or after January 1, 2024, and the count aggregates across form types, so four Forms 1098 plus six Forms 1099-A trigger the requirement.4Internal Revenue Service. General Instructions for Certain Information Returns (2025) A bookkeeper handling your 1099s should be set up to e-file if you are near that volume.
Bookkeepers can also prepare the annual income tax return itself, provided they have registered with the IRS as a paid preparer. The organized records they maintain during the year feed directly into that return, which is why many small businesses use the same person for both jobs.
The PTIN Requirement
Federal law defines a “tax return preparer” as anyone who prepares all or a substantial portion of a tax return for compensation.5Office of the Law Revision Counsel. 26 USC 7701 Definitions Any bookkeeper who prepares a paid return has crossed that line and must obtain a PTIN before charging for the work. The PTIN costs $18.75, expires on December 31 each year, and must be renewed annually, with the renewal window opening in mid-October.6Internal Revenue Service.

A bookkeeper with a valid PTIN is what the IRS calls an unenrolled preparer: authorized to prepare returns, but without the comprehensive federal licensing exam that Enrolled Agents and CPAs must pass. Unenrolled preparers are still bound by the conduct standards in Treasury Department Circular 230, so they must exercise due diligence, ensure accuracy, and meet the ethical requirements that apply to anyone practicing before the IRS.7Internal Revenue Service. Frequently Asked Questions Before hiring a bookkeeper to prepare your return, ask to see a current PTIN. Preparing paid returns without one exposes them to federal penalties and leaves you working with someone operating outside IRS rules.
Where a Bookkeeper’s Authority Stops
Two boundaries matter more than any other: what a bookkeeper can advise on, and how far they can represent you if the IRS asks questions.
Preparation Versus Planning
Preparing a return means organizing financial data and completing the forms current tax law requires. Tax planning is different work: strategic decisions about how to position a business or individual to reduce future taxes. Courts have drawn a line where complex legal questions arise. When a tax question requires interpreting statutes, case law, or regulations to reach a conclusion, answering it for a client can constitute the unauthorized practice of law if the person answering is not a licensed attorney, CPA, or Enrolled Agent.
Bookkeepers can safely categorize deductible expenses, calculate depreciation using standard methods, and prepare returns that reflect what the records show. They should stop short of recommendations that turn on interpreting ambiguous tax rules, such as whether a particular payment structure qualifies as a deductible business expense or whether converting your entity type would save tax. Those questions belong with a credentialed professional.
Representation Before the IRS
The gap widens when the IRS opens an inquiry. Unenrolled preparers, including bookkeepers with a PTIN, can represent a taxpayer only during an examination, and only for returns they personally prepared and signed. Their representation is limited to interactions with revenue agents, customer service representatives, and similar IRS employees, including the Taxpayer Advocate Service. They cannot represent clients before appeals officers, revenue officers, or IRS counsel, even for a return they prepared themselves.8Internal Revenue Service. Treasury Department Circular No. 230 (Rev. 6-2014)
Enrolled Agents, CPAs, and attorneys hold unlimited representation rights and can represent you on any matter, before any IRS office.9Internal Revenue Service. Understanding Tax Return Preparer Credentials and Qualifications If a routine audit escalates to an appeal or a collection dispute, a bookkeeper without additional credentials cannot follow the case with you.
The Annual Filing Season Program
The IRS offers a voluntary program called the Annual Filing Season Program (AFSP) for unenrolled preparers who want to show a higher level of professionalism. Participants complete 18 hours of continuing education each year, including a 6-hour federal tax refresher course with a competency test, 10 hours of federal tax law topics, and 2 hours of ethics.10Internal Revenue Service. General Requirements for the Annual Filing Season Program Record of Completion Completion earns a Record of Completion from the IRS and the same limited representation rights described above: examinations only, for returns the preparer signed, before revenue agents and customer service representatives. AFSP participants still cannot represent clients in appeals or collection matters.9Internal Revenue Service. Understanding Tax Return Preparer Credentials and Qualifications
State Registration May Also Apply
Federal PTIN rules apply everywhere, but a handful of states impose their own registration or licensing obligations on non-credentialed preparers. These typically involve a competency exam, education hours (often 60 to 80), registration fees, and sometimes a surety bond. Requirements vary, so a bookkeeper preparing state returns should confirm what their state requires. Failing to register where required can bring fines or a bar from preparing returns in that state, on top of any federal exposure.
When to Bring In a CPA or Enrolled Agent
A bookkeeper who prepares returns can be a cost-effective option for straightforward situations, such as a sole proprietorship with clear income and expenses or a small business with simple payroll. The arrangement works especially well when the same person has kept the records all year and knows the numbers.
Consider hiring a CPA or Enrolled Agent instead when your situation involves any of the following:
- Filing in multiple states, which raises nexus and apportionment questions beyond data entry.
- Choosing between an LLC, S corporation, or C corporation, which calls for strategic analysis rather than form preparation.
- An IRS notice that could escalate past the initial examination, where unlimited representation rights matter.
- Mergers, acquisitions, significant asset sales, or foreign income reporting, all of which involve rules requiring specialized expertise.
- Proactive tax planning, including retirement plan structuring, estimated tax optimization, or succession planning.
For many small businesses, the strongest arrangement pairs a bookkeeper who handles day-to-day records and recurring compliance with a CPA or Enrolled Agent who reviews the work, signs the annual return, and provides strategic guidance. That split keeps costs manageable and puts someone with full credentials behind the numbers you report to the IRS.
