What a 501 letter is and why you need one
A 501(c)(3) information letter is a document from the IRS that officially recognizes your organization as tax-exempt. It means your nonprofit does not pay federal income tax, and donors can deduct their contributions on their own tax returns. Without this letter, you are a nonprofit in name only — the IRS has not confirmed your status.
You need this letter to open a nonprofit bank account, receive grants from foundations, and file Form 990-N (the annual nonprofit tax return). Many donors and grantmakers will not give money to an organization without proof of 501(c)(3) status. Some states also require the letter before they will grant state tax exemption.
The letter itself is not a one-time thing. The IRS issues it once, and it remains valid unless your organization's status changes or the IRS revokes it. You do not renew it annually, but you do have to file annual returns to keep the status active.
Key Takeaways
- You must first incorporate your organization at the state level and obtain an EIN (Employer Identification Number) from the IRS before you can request a 501(c)(3) letter.
- The standard form to request a 501 letter is Form 1023-EZ (simplified, for organizations with less than $50,000 in projected annual revenue) or Form 1023 (full application, for larger or more complex organizations).
- Form 1023-EZ costs $275 and typically receives a response in two to four weeks; Form 1023 costs $600 and can take two to four months or longer.
- You must describe your organization's mission, structure, governance, and how you will use donations, and you must show that you meet one of the 501(c)(3) categories (charitable, educational, religious, scientific, literary, or similar).
- The IRS will mail your information letter to the address you provide; there is no online portal to check status, so you will need to wait or call the IRS at 877-829-5500 to follow up.
Before you apply: incorporation and your EIN
You cannot request a 501 letter until your organization legally exists. Start by incorporating at your state level — this means filing articles of incorporation with your state's secretary of state office. The process and cost vary by state, but most charge between $50 and $300 and take one to two weeks. Your state will issue a certificate of incorporation once approved.
Next, obtain an Employer Identification Number (EIN) from the IRS. This is a nine-digit number that identifies your organization for tax purposes, similar to a Social Security number for a business. You can apply for an EIN online at irs.gov (search "Apply for an EIN"), by phone at 800-829-4933, or by mail using Form SS-4. Online and phone applications are instant or same-day; mail takes about four weeks.
You will need your EIN before you fill out Form 1023 or 1023-EZ. Have your state incorporation documents and EIN in hand before you start the 501 application.
Choosing between Form 1023-EZ and Form 1023
The IRS offers two paths. Form 1023-EZ is the streamlined version for smaller organizations. You can use it if your organization projects less than $50,000 in annual revenue, has no employees, and does not own real estate or other complex assets. The form is about three pages, costs $275, and you submit it online. The IRS typically responds in two to four weeks.
Form 1023 is the full application and is required if you do not meet the 1023-EZ thresholds. It is much longer (around 15 pages plus attachments), costs $600, and you mail it to the IRS. Processing takes two to four months on average, though some applications take longer if the IRS has questions.
If you are unsure which form fits your situation, the IRS website has a worksheet to help you decide. In general, if you are brand new and small, 1023-EZ is faster and cheaper. If you have any complexity — employees, real estate, significant revenue, or uncertainty — use Form 1023.
What information you must provide
Both forms require you to describe your organization's purpose and how it serves the public. You will need to explain which 501(c)(3) category you fit: charitable (helping the poor, sick, or infants), educational (schools, colleges, research), religious, scientific, literary, or similar. Be specific — "helping the community" is too vague. "Providing free tutoring to low-income elementary students in [city name]" is specific enough.
You must also describe your governance structure: who sits on your board, how board members are chosen, and how decisions are made. The IRS wants to see that your organization is controlled by a board, not by a single person or family. You will need to list your board members' names and addresses.
Form 1023 requires detailed financial projections for the first two years (revenue, expenses, and how you will use donations) and a copy of your bylaws. Form 1023-EZ requires less financial detail but still asks how you plan to spend money. Both forms ask whether you have any unrelated business income (income from activities that are not related to your mission).
Submitting your application and what happens next
Form 1023-EZ is submitted online through the IRS e-services portal. You will need to create an account, upload your EIN documentation, and pay the $275 fee by credit card or electronic bank transfer. You will receive a confirmation number immediately.
Form 1023 is printed and mailed to the IRS address listed on the form (this changes by region, so check the current form). Include a check or money order for $600 and copies of your incorporation documents and bylaws. Keep copies of everything you send.
After submission, there is no online tracking system. The IRS will mail your information letter to the address you provided on the form. If you do not hear back within the expected timeframe (two to four weeks for 1023-EZ, two to four months for 1023), you can call the IRS at 877-829-5500 and provide your EIN and submission date. Have your confirmation number or mailing receipt ready.
What to do if the IRS requests more information
The IRS may send you a letter asking for clarification or additional documents. This is called a request for additional information (RAI) and is common, especially for Form 1023 applications. You will have 30 days to respond. Read the letter carefully — it will specify exactly what the IRS needs.
Common requests include a clearer description of your mission, proof that your board meets regularly, or financial documentation. Respond promptly and directly to what was asked. Do not send extra documents the IRS did not request; stick to what the letter says.
If you disagree with the IRS's decision or believe they misunderstood your organization, you have the right to appeal. The information letter will explain the appeal process if your application is denied.
After you receive your information letter
Once you have your 501(c)(3) letter, keep it safe — you will need to show it to banks, grantmakers, and donors. You do not need to frame it or display it, but you should store a copy digitally and keep the original in a secure place.
Your 501(c)(3) status is not permanent without action on your part. You must file Form 990-N, 990-EZ, or 990 with the IRS every year, depending on your revenue. If you do not file for three consecutive years, the IRS will automatically revoke your status. You will also lose status if your organization dissolves, changes its purpose, or engages in activities that violate 501(c)(3) rules.
Some states require you to register separately for state tax exemption. Check with your state's tax authority — many states accept the federal 501 letter as proof, but some require a separate state application.
Frequently Asked Questions
How long does it actually take to get a 501 letter?
Form 1023-EZ typically takes two to four weeks from submission. Form 1023 usually takes two to four months, but can take longer if the IRS asks questions or if there is a backlog. The total time from incorporation to receiving your letter is usually three to six months if you use 1023-EZ, or four to eight months if you use 1023.
Can I operate as a nonprofit before I get my 501 letter?
Yes. Your organization is legally incorporated and can accept donations and operate once you have your state incorporation certificate and EIN. However, donors cannot deduct their contributions until you have your 501(c)(3) letter, and many grantmakers will not fund you without it. You can start work, but your fundraising will be limited.
What if my organization does not fit neatly into one 501(c)(3) category?
Most organizations fit into more than one category. For example, an organization that runs an after-school program for low-income students is both charitable and educational. Describe all the ways your organization serves the public and let the IRS determine which category applies. Be honest about your activities — do not try to force your organization into a category it does not fit.
Do I need a lawyer to fill out the 501 application?
No, but many organizations hire a lawyer or tax professional to review their application before submitting, especially for Form 1023. If you are confident in your organization's structure and mission, you can complete the form yourself. The IRS website has detailed instructions and examples for both forms.
What happens if the IRS denies my 501 application?
The IRS will send a letter explaining why. Common reasons include an unclear mission, governance problems (like a one-person board), or activities that do not fit 501(c)(3) rules. You can revise your organization's bylaws or mission statement and reapply, or you can appeal the decision within 30 days of the denial letter.
