In this guide, we will cut through the confusion. We will provide the specific tax identification details you need, explain how to verify them independently, and offer insights into managing your benefits with United Association (UA) Local 519. Let’s get your paperwork sorted so you can focus on what matters most—your work and your well-being.
What Is the Plumber Local 519 Health And Welfare Fund Tax Id?
The term “Tax ID” in the context of union benefit funds refers to the Employer Identification Number (EIN) assigned by the Internal Revenue Service (IRS). This nine-digit number is used to identify the business entity—in this case, the trust fund that manages health, welfare, and pension benefits for the members of Plumbers and Pipefitters Local Union No. 519.
It is important to distinguish between different entities within the union structure:
- The Union Local: Handles membership dues, collective bargaining, and job referrals.
- The Health and Welfare Fund: A separate legal trust entity that manages medical, dental, and vision benefits.
- The Pension Fund: Manages retirement savings.
Each of these entities may have its own distinct EIN. Using the wrong number can lead to delayed payments, rejected claims, or errors in your annual tax reporting (such as Form 1095-C). Therefore, accuracy is not just a bureaucratic preference; it is a financial necessity.
Why Do You Need This Number?
You will typically need the Plumber Local 519 Health And Welfare Fund Tax Id for several critical reasons:
- Employer Contributions: If you are self-employed or running a small contracting business, you must use this EIN when sending monthly benefit contributions to the fund.
- Tax Filings: Employers use this number to report health coverage offers to the IRS under the Affordable Care Act (ACA).
- Verification of Coverage: Insurance providers and hospitals may request this number to verify the legitimacy of the trust fund during eligibility checks.
- Audit and Compliance: During internal or external audits, matching contributions to the correct Tax ID ensures that every dollar paid is accounted for in your member account.

How to Locate and Verify the Correct EIN
While information can sometimes be found on general union directories, relying on third-party sites can be risky due to outdated data. The most reliable method is to consult official documentation provided directly by the fund.
Step-by-Step Verification Process
- Check Your Benefit Booklet: Every member receives a Summary Plan Description (SPD). The EIN is usually listed on the first or last page under “Plan Administrator” or “Trustee Information.”
- Review Pay Stubs: If you are employed by a signatory contractor, your pay stub may list the deduction code along with the fund’s identification number.
- Contact the Fund Office Directly: This is the gold standard for verification. Speaking to a representative ensures you have the most current information, especially if there have been recent mergers or administrative changes.
Pro Tip: Always keep a digital copy of your benefit card and the fund’s contact information saved in your phone. Administrative offices may change phone numbers or locations, but the EIN rarely changes once assigned.

Common Mistakes When Submitting Union Benefits Data
Even experienced contractors can make errors when handling union benefit administration. Here are the most frequent issues encountered by the Local 519 administration office:
- Confusing Local Numbers: There are many UA Locals across the country. Confusing Local 519 with Local 170, Local 38, or others will result in misdirected funds.
- Using the Union’s EIN for the Welfare Fund: As mentioned earlier, the union hall and the benefit trust are separate legal entities. They have different EINs.
- Typos in Member IDs: While the Tax ID identifies the fund, the Member ID identifies you. Both must be correct on remittance reports.
According to industry standards for labor-management trusts, accurate data entry reduces administrative overhead by up to 30%, allowing more funds to be directed toward actual member benefits rather than corrective processing. For more context on how labor unions operate structurally, you can refer to general information on Trade Unions.

FAQ Section
1. Is the Tax ID for the Pension Fund the same as the Health and Welfare Fund?
No. In most union structures, including UA Local 519, the Pension Fund and the Health and Welfare Fund are separate trusts with distinct Employer Identification Numbers (EINs). You must use the specific EIN for the fund to which you are contributing. Check your remittance report to see if you are paying into one combined bill or two separate ones.
2. Where can I find the Plumber Local 519 Health And Welfare Fund Tax Id online?
The most secure place to find this information is on the official UA Local 519 website or the specific portal used for benefit management (often platforms like Velos or similar union benefit portals). Avoid using random “EIN lookup” websites, as they may provide outdated or incorrect data for private trust funds.
3. What happens if my employer uses the wrong Tax ID?
If the wrong Tax ID is used, the payment may be rejected by the bank or held in a suspense account by the fund. This can lead to a lapse in your health coverage. It is crucial to notify your employer’s payroll department immediately to correct the error and request a retroactive payment if necessary.
4. Do I need the Tax ID for filing my personal taxes?
Generally, no. As a member, you do not use the fund’s EIN on your personal 1040 tax return. However, you may receive Form 1095-C from your employer, which reports the health coverage offered to you. The employer uses the fund’s EIN on their corporate filings, but you primarily need your own Social Security Number for personal tax purposes.
5. How often does the Tax ID change?
An EIN is a permanent identifier for a legal entity. It rarely changes unless the fund undergoes a major legal restructuring, merger, or dissolution. However, contact information (phone numbers, addresses) changes more frequently. Always prioritize verifying the EIN once and then saving it securely.
6. Can I access my benefit details without the Tax ID?
Yes. To access your personal benefit details, claim status, or provider directories, you typically need your Member ID and date of birth, not the fund’s Tax ID. The Tax ID is primarily for administrative, payroll, and legal identification purposes.
Conclusion
Securing the correct Plumber Local 519 Health And Welfare Fund Tax Id is a small step that prevents significant headaches down the road. Whether you are ensuring your health coverage remains uninterrupted or verifying that your business contributions are compliant, having this nine-digit number on hand is essential.
Remember, the key to smooth union benefit administration is accuracy and communication. Keep your benefit booklets handy, verify numbers with the fund office directly when in doubt, and ensure your employer is using the correct EIN for the Health and Welfare Trust—not the general union local.
