The cost to set up an irrevocable trust generally runs $2,000 to $10,000 or more in attorney fees, and that is only the drafting bill. Funding the trust brings its own expenses — new deeds, appraisals, and often a federal gift tax return — and once the trust exists, annual tax preparation and trustee fees continue for its lifetime.
Attorney Fees for Drafting the Trust
The estate planning attorney who writes the trust is the biggest single line item. Most attorneys quote a flat fee that covers the initial consultation, custom drafting, and a signing meeting. Ask for that flat number in writing before work starts so an extra revision or meeting doesn’t push the bill up.
For a straightforward irrevocable trust holding conventional assets with simple distribution terms, flat fees generally run $2,000 to $5,000. Trusts built around asset protection, generation-skipping strategies, or business succession usually land in the $5,000 to $10,000 range, and can go higher. Attorneys who bill hourly typically charge $250 to $600 per hour depending on location and specialization; if you’re paying by the hour, get a written hours estimate up front.
Online legal services sell basic trust packages starting around $400 to $650. They work from templates and are best suited to simple estates with standard goals. An attorney, by contrast, builds the document around your tax situation, family dynamics, and asset mix. The reasons most people choose an irrevocable trust in the first place — tax planning, creditor protection, benefits eligibility — are the same reasons the template approach tends to fall short.
What Pushes the Price Higher
Two things drive the drafting fee more than anything else: what you’re putting into the trust, and who gets what.
On the asset side, a brokerage account is easy. A commercial building, a stake in a family business, and an art collection each require their own legal handling, title work, and third-party coordination. Every additional asset type adds drafting time.
On the distribution side, a single beneficiary with a clean instruction to distribute at age 30 is a fraction of the work of a trust serving multiple beneficiaries across generations, with conditions tied to college graduation, matching earned income, or other milestones. Every contingency needs its own language, and each one has to address what happens if the condition is never met.
Specialized provisions add another layer of cost. A supplemental needs trust for a beneficiary receiving Medicaid or Supplemental Security Income has to be drafted so those benefits aren’t disrupted. Charitable components, spendthrift protections, and advanced tax planning all push fees toward the top of the range.
Upfront Costs Beyond the Attorney
Once the document is signed, you still have to move assets into the trust. That process carries its own expenses.
Employer Identification Number
An irrevocable trust that isn’t treated as a grantor trust needs its own EIN, because it is a separate tax entity. The IRS issues EINs for free through its online application in a few minutes.1Internal Revenue Service. Get an Employer Identification Number Third-party sites that charge $50 to $150 to file for you are selling something you can do yourself at no cost. Your attorney may handle this as part of the flat fee, so confirm before paying anyone separately.
Real Estate Transfer Costs
If real property is going into the trust, a new deed has to be drafted and recorded with the county. Deed preparation is usually a few hundred dollars, sometimes included in the attorney’s fee. Recording fees vary by county. Some jurisdictions also charge a transfer tax based on the property’s value, though not every state applies it to transfers into a trust. Ask your attorney whether it applies in your state before you assume the number.
Appraisals
Any asset without a readily determined market value likely needs a professional appraisal, especially business interests, real estate, collectibles, and artwork. The IRS may require one to substantiate the value reported on a gift tax return. Appraisal costs range from a few hundred dollars for a single property to several thousand for a complex business valuation.
Account Retitling and Notary Fees
Banks and brokerages sometimes charge fees to retitle accounts in the trust’s name, though many waive them. Notary fees for signing the trust are modest, generally $2 to $25 per signature depending on your state.
Gift Tax Filing Costs When You Fund the Trust
Transferring assets into an irrevocable trust is a gift for federal tax purposes. Once you give up the right to take the assets back, the IRS treats the transfer as a completed gift to the trust’s beneficiaries, which can require filing Form 709 and can reduce your lifetime exemption.
For 2026, you can give up to $19,000 per recipient without gift tax consequences. A trust with three beneficiaries could receive up to $57,000 within the annual exclusion, and married couples can double those figures by electing gift-splitting. Transfers above the annual exclusion don’t necessarily mean tax is owed; they reduce your lifetime estate and gift tax exemption, which is $15,000,000 per person in 2026.2Internal Revenue Service. Revenue Procedure 2025-32
There’s a catch on the annual exclusion. It only applies to gifts of a “present interest” — property the recipient can use or enjoy right away. Most irrevocable trust transfers create future interests, so attorneys commonly include a Crummey provision giving beneficiaries a short window to withdraw their share of each contribution. Without that language, even a $10,000 contribution can require a gift tax return.3Internal Revenue Service. Instructions for Form 709
Preparing Form 709 typically costs a few hundred dollars if it’s handled alongside your regular tax return, and more when the gift involves hard-to-value assets like business interests that need a formal appraisal. Budget for it if you’re funding the trust with anything worth more than the annual exclusion. For most people whose estates sit well under the $15,000,000 exemption, no gift tax will actually be owed, but a return may still be required and the exemption usage still has to be tracked.4Internal Revenue Service.

Ongoing Costs After the Trust Is Funded
Setup is a one-time expense. Running the trust is not.
Trustee Compensation
The trustee is entitled to reasonable compensation. A family member may waive fees, but a professional or corporate trustee will charge. Corporate trustees typically charge an annual fee calculated as a percentage of assets under management, commonly 1% to 2% per year. On a $1 million trust, that’s $10,000 to $20,000 annually. Some also charge based on trust income or on specific transactions like a real estate sale. Ask for the full fee schedule before naming a corporate trustee in the document.
Tax Preparation
The trust must file its own federal income tax return on Form 1041 each year if it has any taxable income, gross income of $600 or more, or a beneficiary who is a nonresident alien. The trustee also has to furnish each beneficiary with a Schedule K-1 showing their share of the trust’s income.5Internal Revenue Service. Instructions for Form 1041 and Schedules A, B, G, J, and K-1 Professional preparation of a trust return runs from around $500 for a simple trust to several thousand for one with complex investments or multiple beneficiaries.
Fiduciary Bond Premiums
Some trust documents or court orders require the trustee to obtain a surety bond as protection against mismanagement. Premiums typically start around 0.5% of the covered amount for the first $250,000, with rates varying by the trustee’s creditworthiness and the total assets involved. Many trust documents waive the bond requirement to avoid this recurring cost, which is worth raising with your attorney during drafting.
The Cost of Changing an Irrevocable Trust Later
“Irrevocable” suggests permanence, but changes are sometimes possible. They’re just expensive, which is why getting the drafting right the first time saves money later.
The simpler path is trust decanting, available in a majority of states. The trustee pours assets from the existing trust into a new trust with updated terms. Because that means drafting a whole new trust agreement, attorney fees for decanting commonly run at least 30% of what the original trust cost to create, and more if the changes are substantive.
The harder path is judicial modification, where you petition a court to change or terminate the trust. That means court filing fees, attorney time for preparing and arguing the petition, and often months of proceedings. Contested trust litigation can reach tens of thousands of dollars in attorney fees, and disputes involving multiple parties escalate from there. In some jurisdictions the court can order fees paid from the trust itself, which means the beneficiaries ultimately absorb the cost.
Total Cost Estimates by Complexity
Adding the pieces together, here is a rough picture of what to expect at each level:
- Simple irrevocable trust: $2,500 to $6,000 upfront. Covers attorney fees for a trust with conventional financial assets, one or two beneficiaries, straightforward distribution terms, and minimal transfer costs. Annual costs of $500 to $2,000 for tax preparation, plus trustee fees if you use a professional.
- Moderate complexity: $6,000 to $15,000 upfront. Multi-beneficiary trusts, conditional distributions, real estate transfers requiring deed preparation and recording, one or more appraisals, and a gift tax return. Annual costs of $1,500 to $5,000 for tax preparation and trustee compensation are common.
- High complexity: $15,000 or more upfront. Trusts with business interests, multi-generational planning, special needs provisions, multiple properties across jurisdictions, and significant gift tax planning. Annual administration can easily exceed $10,000 once professional trustee fees, tax preparation, and investment management are combined.
These ranges don’t include any gift tax actually owed when the trust is funded, which depends entirely on the value transferred and your remaining lifetime exemption.
