Understanding the 2023 Federal Tax Return Mailing Guide
The 2023 Federal Tax Return Mailing Guide is an informational resource created by the IRS that explains how to submit your federal income tax return by mail. Unlike digital filing methods, mailing your return means printing forms, including them in an envelope, and sending them through the postal service to an IRS processing center. This guide exists because the IRS recognizes that not everyone files taxes online—some people prefer paper forms, have limited internet access, or feel more comfortable with traditional mailing methods.

Here's what makes this guide particularly useful: it provides the specific mailing addresses for different types of returns based on your situation. The address you use matters. If you send your return to the wrong location, it may take longer to process, or you might face delays in receiving refunds. The guide breaks down which address to use depending on whether you're sending a 1040 form, a business return, an amended return, or other specific tax documents.
The 2023 tax year refers to income you earned between January 1 and December 31, 2023. You would typically file this return in early 2024. The guide contains information current to that filing period and includes the correct mailing addresses that were active during that time. Since IRS processing addresses can change year to year, using the correct guide for your filing year matters.
Many people don't realize there are actually multiple IRS processing centers across the country. Your return gets routed to different locations depending on your state, the type of return you're filing, and whether you're including a payment or expecting a refund. The mailing guide helps you navigate this system by telling you exactly where to send your envelope.
Practical Takeaway: Before you print and mail any tax return, locate the free 2023 Federal Tax Return Mailing Guide from the IRS website. This single document will show you the correct address for your specific situation, which is the most important step to ensure your return reaches the right place without delays.
Breaking Down the IRS Mailing Addresses by State and Return Type
The 2023 mailing guide organizes addresses in a straightforward way: first by whether you're including a payment with your return, and then by your state of residence. This matters because the IRS processes returns at regional centers. If you live in California, your return goes to a different address than someone filing from Maine. If you're sending a check with your return, it goes to yet another location—one equipped to handle payments and match them to your account.

Let's walk through an example. Say you live in Texas, you're filing a standard 1040 form, and you expect a refund (no payment enclosed). The guide will direct you to the IRS processing center that handles Texas returns without payments. If instead you live in Texas but you're sending a check for $2,000 that you owe, your mailing address changes completely—because that payment needs to go to a location with payment processing capabilities. The guide shows both addresses clearly.
For taxpayers in northeastern states like New York, New Jersey, and Connecticut, there's a dedicated regional center. Similarly, southern states, midwestern states, and western states each have their routing instructions. The guide presents this information in a table format, which means you can find your state quickly and identify the correct address without confusion.
One detail many people overlook: the guide distinguishes between different types of forms. A standard 1040 individual income tax return has one mailing address, while a 1040-SR (for people age 65 and older) may have the same or a different routing, and business returns like a 1065 have their own locations entirely. If you're filing an amended return (a 1040-X), that also goes to a specific address. The guide spells out all these distinctions.
The addresses in the guide also include apartment numbers or suite numbers for the specific IRS offices. This level of detail is crucial because the IRS building might be a large federal facility, and your mail needs to reach the right department within that building. Leaving out this information could result in mail being delayed or misdirected.
Practical Takeaway: Open the mailing guide, locate your state in the address section, confirm the type of return you're filing, and note whether you're enclosing a payment or filing to receive a refund. Write down the exact address shown—including all numbers, suite information, and ZIP code. Use this as your mailing label.
What to Include When Mailing Your Return
Simply having the correct address isn't enough; you also need to know what documents to include in your envelope. The mailing guide provides a checklist of items that should accompany your tax return. This section of the guide helps prevent one of the most common problems: sending incomplete returns that require follow-up from the IRS.

At minimum, your mailed return should include your actual tax form—typically the 1040 and any schedules that apply to your situation. Schedules are additional forms attached to your main return; for example, if you have investment income, you'd include Schedule B. If you're self-employed, you'd include Schedule C. The guide doesn't tell you which schedules you need (that depends on your personal financial situation), but it does remind you that missing schedules can cause problems.
If you're enclosing a payment, you must include a payment voucher—a form that tells the IRS which account your payment belongs to and for what tax year. Sending just a check without this voucher creates a significant problem: the IRS may not know which return the payment is for. The guide explains what payment voucher form to use. For 2023 returns paid by check, this is typically the 1040-V form. For other return types, different vouchers apply.
The guide also covers what NOT to include. Don't staple documents together unnecessarily. Don't use paper clips. Don't fold your return multiple times. These guidelines exist because the IRS processes returns with high-speed scanning equipment. When returns are mangled, stapled in ways that jam the machines, or folded into origami, they either slow down processing or get flagged for manual review, which delays your refund or response.
Another point the guide addresses: supporting documentation. If you're mailing a return with attached schedules, you should not include receipts, bank statements, or other supporting documents unless the IRS specifically requests them. Including extra documents just slows down processing. However, you should keep copies of everything at home for your own records in case the IRS ever questions your return.
The guide also reminds filers that if they're claiming certain deductions or credits—particularly those that are less common—they may need to include specific forms or certifications. For example, if you're claiming an education credit, you might need to include Form 8863. The guide either lists these requirements or directs you to the form instructions.
Practical Takeaway: Create a checklist before you seal your envelope: (1) Your completed main tax form, (2) All required schedules for your situation, (3) Payment voucher if you're sending money, (4) Copies of any forms the IRS requires for credits or deductions you're claiming. Double-check that you've signed and dated the return. Then seal and mail.
Mailing Standards and Handling Tips to Avoid Delays
The 2023 Federal Tax Return Mailing Guide includes practical information about how to physically prepare and send your return to minimize processing delays. These details might seem minor, but they can significantly affect how quickly your return is received and processed.

First, the envelope itself matters. The guide recommends using a standard business envelope (9x12 inches is typical) that's large enough to fit your forms without excessive folding. Your forms should lie relatively flat in the envelope. This matters because the scanning equipment at the IRS processing centers works best with flat documents. Crumpled or heavily folded returns get caught in sorting equipment or have to be manually sorted, adding days or weeks to processing time.
Regarding postage: make sure you use correct postage for the weight of your envelope. The guide doesn't specify exact postage amounts (since that changes based on postal service rates), but it does emphasize that incorrect postage leads to delayed delivery. If your envelope arrives with insufficient postage, the post office may attempt to deliver it with "postage due" marking, which the IRS may refuse. Your return then goes back to you, and you have to resend it. To be safe
