What is an IRS CP504 Tax Notice Letter and How To Respond


IRS Notice CP504 – What Does It Really Mean?

Every year, the IRS sends out millions of tax bills to taxpayers around the country. The agency is required to put taxpayers on notice about their back taxes. They must give them an opportunity to respond before any enforcement action is taken. Initially in the Collection Process, taxpayers may receive a Notice CP14 from the IRS. However, if there is no response or the tax debt has not been fully resolved, the IRS will issue a Notice CP504 Notice of Intent to Seize (Levy) Your Property or Rights to Property.

CP504 Certified Mail – How To Pay Online

Typically, the IRS will send you a CP504 Notice via Certified Mail. To meet strict requirements under the tax law, the agency has to mail the letter to your “last known address”. This is usually the mailing address listed on your last tax return.

The Notice states: “If you don’t call us immediately to make payment arrangements or pay the amount due within 30 days from the date of this notice, we may levy your property or rights to property and apply it to the tax you owe.”

For taxpayers who agree with the amount due on the notice, and can full pay, the IRS provides for several ways to make a payment.

If you agree with the IRS balance, but cannot full pay the tax due, you may be able to set up an affordable installment agreement in order to pay the taxes over time. Taxpayers who receive a CP504 Letter must follow IRS rules and procedures to prevent a tax lien from being filed and levies from being issued. For guidance, and to explore if a reduction or removal of IRS penalties is possible, contact Landmark Tax Group  for a no-obligation consultation.


If you disagree with, or if you can’t full pay, the CP504 Notice, the IRS must be immediately contacted and informed of your position and intentions. Should the IRS fail to hear from you or your Tax Representative, the agency is mandated to proceed with enforced collection action, including filing tax liens, issuing bank levies, garnishing your wages, and seizing your valuable assets. The IRS is also required to assess penalties and interest against you for the unpaid tax. See 10 Ways to Get IRS Penalties Removed.


Since the CP504 Notice requires a quick response, you will need to determine if the taxes can be fully paid. If not, it’s vitally important to get tax help right away from a licensed and experienced Tax Representative to ensure the IRS does not take enforcement action against you. The IRS needs to be informed in a timely manner that you will be making arrangements to pay your tax debt under the guidelines and criteria made available by the Tax Code. If you’re unable to full pay your tax debt, you’ll need help setting up an affordable payment plan, filing for a tax settlement (aka offer-in-compromise), or requesting a reduction of penalties.

Very good experience and glad I made the decision to use this company. Michael was professional and courteous in all of my dealings with him. My tax dilemma was quickly resolved and Michael even waived much of his normal fee. Where else have you heard of a business doing that? Without question, I would recommend Landmark Tax Group for anyone seeking a fair resolution for a tax problem.

Great service! Michael really knows his stuff and goes above and beyond. They delivered more than they promised and helped me get an AWESOME resolution to my case.  I highly recommend them.

I worked with Landmark Tax Group to help sort through my LLC, 501c(3) and personal finance questions. They were prompt, friendly and extremely knowledgeable. This was the best experience I’ve had with a tax company. I would HIGHLY recommend them!

Great service!!! Very diligent and most importantly high integrity. One of those rare occasions when someone is looking out for your best interest.

Michael was fantastic! He understood my case very quickly, got right to work and was super prompt with communications. His professionalism and his friendly demeanor immediately put me at ease. I whole heartedly recommend contacting them if you’re in need of advice and assistance.

I received great advice in how to deal with the FTB, i don’t review often, but when someone is honest and legitimate, they do deserve a review.  My questions were answered, and if i didn’t quite understand, Micheal was more than willing to give me follow-up answers to better help me.  I highly recommend Landmark Tax Group, just for the mere fact that they treat you as a human being, Not a cash cow.

I had some returns from previous years to complete after receiving a hefty bill from the California Franchise Tax Board.  Michael was prompt in answering my questions and very helpful and reassuring.  We had several back and forth communications and this was all done for free since they do not prepare tax returns.  He gave me some contacts and advice and now I’m on my way to getting my situation resolved.  I’m very thankful for his advice and guidance.

While Michael’s scope of practice meant that we ultimately could not work directly to resolve the issue I was having, he was very prompt, professional, generous and kind in taking time out of his schedule to consult with me, refer me to his network of colleagues- not just once, but a second time even months after. Some professionals are just after services and compensations but Michael strikes me as someone who genuinely cares about your situation and wants to see to it that it gets resolved. These other reviews speak to that as well. You never want to be in a situation where you need to be looking up tax help, but God forbid you ever are, Michael is the person you want in your corner!

Michael and Landmark Tax Group were simply awesome. I like so many others had a year’s old tax issue arise with California FTB. I no longer live there which compounded the stress of the situation. The state had seized monies and filed a lien. After a call to an online tax relief place and some sketchy phone calls I was so happy to find Michael and immediately felt in good hands… at a time of considerable panic.
Fast forward to today and with his help I am totally debt free. He saved me $23,000
I highly recommend Michael and Landmark Tax Group

Michael Raanan is an angel! Michael went above and beyond for me. He was very knowledgeable, professional and very thorough! He is easy to talk to and amazing at what he does. I have a feeling that everyone at landmark tax group shares this way of professionalism! I highly recommend coming here for any and all of your tax help. They will help you and you will be more than pleased with them. 🙂

After calling the other highly advertised tax assistant agency’s and being disappointed with how they responded to my tax matter, I feel fortunate to have found out about the Landmark Tax Group. Michael was very understanding of my situation, and I felt very comfortable dealing with him. He was very knowledgeable and professional in handling our tax issue in a timely manner. I would highly recommend The Landmark Tax Group to anyone who needs assistance in dealing with the IRS.

Wow, just wow. I called Michael today to ask about some major tax issues I had with a defunct corporation I’d started years ago. Michael talked to me for about half an hour, walking me through options and generally helping me understand my options.

Because of him, I’m going to rest nicely tonight for the first time in weeks. It was great to hear that he used to work in IRS collections for 8 years too… which made me feel a lot more secure in his answer.

In all, I’m completely stunned by the level of service he gave to a random stranger who called in and wasn’t going to turn into any revenue for him. I have to imagine that his level of service for actual customers is unreal.

Fast, dependable, reliable, full transparency.  Michael Raanan of Landmark Tax Group allayed my fears spending the rest of my senior years paying my tax debt.  As a result of his extensive knowledge of the tax code, the right questions to ask, and his dedication to my case, I had information, resolution and a plan of action within 24 hours, start to finish.  Amazing!  I highly recommend Landmark Tax Group!

We were very pleased with the expert assistance we received from Michael Raanan at Landmark Tax Group.  In a matter of months we had a resolution to our IRS tax issue.  He was very knowledgeable, professional, explained things in easy to understand terminology & was very easy to discuss our tax issues with.  We called around to other tax groups & just felt the most comfortable speaking & working with Michael.  We are happy to recommend him & his firm.

Great place for tax [relief] advice. Even if they don’t see a need for you to use and pay for their service, they’ll still give you excellent advice and direction at no cost. They are worth a call.

Michael Raanan represents the highest level of professionalism, integrity, decency, and true concern for his clients. His advice every step of the way was right on target.  The end result was a savings of $13,000 on my taxes.

I have already referred him to the other members of my financial team and have complete confidence in referring any clients to him. He is a shining star in his field.

Oh, did I mention how reasonable his fees are? Exceptional considering the amount of attention he provides.
