Yes, accountants do file your taxes. A licensed tax professional gathers your documents, prepares your federal and state returns in professional software, has you review and sign them, and then transmits them electronically to the IRS on your behalf. You still sign the return under penalty of perjury, so the legal responsibility for what it says stays with you, but the preparation and the actual filing are handled by the preparer.
Who Is Allowed to File Your Return for You
The IRS recognizes three categories of practitioners who can prepare returns and represent you before the agency:
- Certified Public Accountants (CPAs), who are licensed by their state board after meeting education and experience requirements and passing a four-section exam covering auditing, financial accounting, tax regulation, and a chosen discipline.1AICPA & CIMA. Everything You Need to Know About the CPA Exam
- Enrolled Agents (EAs), who specialize in tax and earn the designation by passing a three-part IRS exam or through prior IRS employment.
- Tax attorneys, who hold law degrees and focus on disputes, litigation in tax court, and complex planning.
Anyone paid to prepare a federal return, regardless of credential, must hold a Preparer Tax Identification Number (PTIN) from the IRS and put it on every return they file.2Office of the Law Revision Counsel. 26 US Code 6109 – Identifying Numbers A preparer who leaves off a valid PTIN faces a $60 penalty per return.3Internal Revenue Service. Tax Preparer Penalties If you are hiring someone to file for you, ask for their PTIN before you hand over documents.
What You Give Your Accountant
Most accountants send a tax organizer before your first meeting. It collects Social Security numbers and birth dates for you, your spouse, and each dependent. Small errors here delay processing and can cause credits to be denied.
On top of the organizer, bring your income documents:
- Form W-2 for wages and withholding from each employer.4Internal Revenue Service. About Form W-2, Wage and Tax Statement
- Form 1099-NEC for freelance or contract work.
- Forms 1099-INT and 1099-DIV for interest and dividend income.
- Form 1099-B for proceeds from stock or asset sales.
- Form 1098 for mortgage interest paid.
If you plan to itemize, bring receipts and statements for charitable donations, unreimbursed medical expenses, and state and local taxes paid. Medical expenses are deductible only to the extent they exceed 7.5% of your adjusted gross income.5Internal Revenue Service. Topic No. 502, Medical and Dental Expenses
How Your Return Gets Prepared and Signed
Your accountant enters your data into professional tax software, which populates the appropriate lines of Form 1040 or the applicable business return, applies the current tax rates, and calculates your balance or refund. Your filing status determines both which brackets apply and which standard deduction you get. For tax year 2026, the standard deduction is $16,100 for single filers and $32,200 for married couples filing jointly, and marginal rates run from 10% to 37%.6Internal Revenue Service. IRS Releases Tax Inflation Adjustments for Tax Year 2026 Your preparer compares itemized deductions against the standard deduction and uses whichever is larger.
Before anything goes to the IRS, your accountant must give you a completed copy of the return to review.7Office of the Law Revision Counsel. 26 US Code 6107 – Tax Return Preparer Must Furnish Copy of Return to Taxpayer and Must Retain a Copy or List Check every figure and every name. A missing W-2 or misspelled dependent is much easier to fix now than after transmission.
When you sign, you are declaring under penalty of perjury that the return is true and complete. That declaration is yours, not your accountant’s. If the IRS later finds unreported income or unsupported deductions, the taxes, interest, and penalties fall on you. Your preparer must keep a copy of the return, or a list of taxpayer names and identification numbers, for at least three years after the end of the filing period.7Office of the Law Revision Counsel. 26 US Code 6107 – Tax Return Preparer Must Furnish Copy of Return to Taxpayer and Must Retain a Copy or List
How the Return Actually Reaches the IRS
Once you approve the final return, you sign Form 8879. That form is your authorization for the accountant to transmit the return electronically. They send the encrypted data through the IRS Modernized e-File (MeF) system using authorized e-file software, and the system generates a receipt confirming the transmission.
Within roughly 24 to 48 hours, the IRS issues an electronic acknowledgment showing whether the return was accepted or rejected. A rejection comes with a specific error code. Common causes include a mismatched Social Security number or a dependent already claimed on someone else’s return. Your accountant corrects the flagged issue and re-transmits. The acceptance notice is your official proof of filing, so keep it with your records.
Deadlines and Extensions
For most individuals, the deadline to file a 2025 return is April 15, 2026.8Internal Revenue Service. IRS Announces First Day of 2026 Filing Season If you need more time, your accountant can file Form 4868, which grants an automatic six-month extension to October 15, 2026.9IRS.gov. Application for Automatic Extension of Time to File US Individual Income Tax Return, Form 4868 An extension buys time to file, not time to pay. Any balance owed is still due April 15, and unpaid amounts accrue interest and late-payment penalties after that date.
If you are self-employed, earn investment income, or otherwise have no withholding, you probably owe quarterly estimated tax. For 2026, those payments are due April 15, June 15, September 15, and January 15, 2027.10Taxpayer Advocate Service. Making Estimated Payments Your accountant can calculate the amounts from your projected income so you avoid underpayment penalties.
Getting Your Refund or Paying What You Owe
If the return shows a refund, direct deposit is the fastest way to receive it. The IRS typically issues refunds on e-filed returns within about three weeks of acceptance.11Internal Revenue Service. Refunds You can check status with the “Where’s My Refund?” tool on irs.gov or the IRS2Go app, usually starting 24 hours after e-filing.
If you owe, the IRS accepts several payment methods:
- Electronic funds withdrawal, which your accountant can set up as a direct debit at the time of e-filing.
- IRS Direct Pay, a free online option that lets you pay now or schedule a payment up to a year ahead.
- EFTPS, the free government payment service, which requires enrollment and is useful for estimated payments.
- Debit card, credit card, or digital wallet through approved processors, with processing fees.
- Check or money order mailed with a payment voucher to the address in the return instructions.
Each option runs through irs.gov, and your accountant can help pick the one that fits.12Internal Revenue Service. Payments
If Your Preparer Makes a Mistake or Acts Improperly
You are on the hook for what the return says, but the IRS does hold preparers accountable through its own penalty system for understatements, procedural failures, and lack of due diligence on credits like the Earned Income Tax Credit and Child Tax Credit.3Internal Revenue Service. Tax Preparer Penalties
If you believe a preparer filed a return without your consent, altered your documents, fabricated income or deductions, or redirected your refund, you can report them using Form 14157 (Complaint: Tax Return Preparer) and, if your return was affected, Form 14157-A (Tax Return Preparer Fraud or Misconduct Affidavit). Complaints can be submitted online, by fax, or by mail.13Internal Revenue Service. Make a Complaint About a Tax Return Preparer The IRS generally does not handle fee disputes or state and local tax complaints, and complaints older than three years are typically not actionable.
On the data side, tax preparation firms are classified as financial institutions under the Federal Trade Commission’s Safeguards Rule, which requires them to maintain a written information security program, encrypt client data in storage and in transit, use multi-factor authentication for systems that access your information, and dispose of records securely.14Federal Trade Commission. FTC Safeguards Rule: What Your Business Needs to Know
What It Costs to Have an Accountant File for You
Fees vary with the complexity of your return, your location, and the preparer’s experience. Professionals generally price one of three ways: a flat fee per form or entity, an hourly rate, or a scope-based quote given before work starts. Hourly rates for CPAs typically fall between $150 and $400. A simple return with one W-2 and the standard deduction costs far less than a return with business income, rental properties, or multistate filing. Ask for a fee estimate during your initial consultation and get it in writing if you can.
