Best Tax Software for Trusts: Platforms, Features, and Filing

The best tax software for trusts depends on who you are and how complicated the trust is. An individual executor closing out one straightforward estate can file with TurboTax Business for around $100 to $200. A CPA or attorney handling several fiduciary returns a year should look at Drake Tax, Intuit ProSeries, or CCH Axcess Tax. Bank trust departments and large firms processing volume typically run on Thomson Reuters ONESOURCE or CCH Trust US. Picking the wrong tier is the most common mistake: overspending on enterprise software for one simple return wastes money, and underspending on a consumer product for a complex irrevocable trust costs something worse than money.

Why Trust Returns Need Their Own Software

Trusts and estates aren’t taxed like individuals. They file Form 1041, and the central problem the software has to solve is how much income stays inside the entity (taxed there) versus how much flows out to beneficiaries on Schedule K-1 (taxed on their returns). That split is governed by Distributable Net Income, which caps the entity’s distribution deduction and dictates what each beneficiary reports.¹ Consumer products like TurboTax Deluxe or H&R Block don’t touch any of this.

The reason the math matters so much is that trust brackets are brutally compressed. For 2026, a trust hits the top 37% federal rate at just $16,000 of taxable income, while an individual doesn’t get there until roughly $626,000.² Every dollar the software leaves inside a trust that could have been distributed to a beneficiary in a lower bracket gets taxed at a punishing rate. Small allocation errors produce outsized tax bills.

A domestic trust or estate has to file Form 1041 if it has gross income of $600 or more, any taxable income, or any nonresident alien beneficiary.¹ That threshold catches almost any trust holding interest-bearing or dividend-paying assets.

A Boundary: Grantor Trusts

If you set up a revocable living trust and you’re still alive, the IRS treats all its income as yours. The trust may file a Form 1041 with only entity information and an income attachment, and the grantor reports everything on Form 1040. In many single-grantor situations, an optional filing method skips Form 1041 entirely.³ If the only trust you administer is a standard revocable living trust, you probably don’t need specialized fiduciary software at all until the grantor dies and the trust becomes irrevocable.

Matching Software to Your Situation

Start with three questions before comparing product features. What kind of trust are you filing for? How many fiduciary returns do you prepare in a year? And does the trust touch multiple states?

Individual executor or trustee, one simple estate or non-complex trust. TurboTax Business. The guided interview handles basic income reporting and a small number of Schedule K-1s at consumer pricing.
Individual trustee, non-grantor trust with varied income or several beneficiaries. Drake Tax or an entry-level CCH Axcess subscription. The DNI automation and K-1 handling justify the step up from TurboTax Business, and you’ll spend less time checking allocations by hand.
CPA or attorney handling multiple fiduciary returns. CCH Axcess Tax, Intuit ProSeries, or Drake Tax. Cloud access matters if reviewers and preparers share the file. ProSeries produces audit-ready workpapers; Drake is priced for firms that do fiduciary work alongside a broader individual and business practice.
Large firm or institutional trust department. Thomson Reuters ONESOURCE or CCH Trust US. Batch processing and direct custodial data imports are what justify the enterprise cost.

One pattern trips people up: a trust that starts simple rarely stays simple. An estate that begins by collecting a few dividend checks ends up holding real estate, generating income in several states, or making charitable distributions. Choosing software with room to grow, even if you don’t need every feature this year, avoids migrating mid-engagement.

The Main Platforms

TurboTax Business

The primary consumer option, running in the $100 to $200 range per return. An interview-style interface walks non-professionals through Form 1041, generates K-1s for a small number of beneficiaries, and supports federal e-filing. The ceiling appears fast. Multi-state K-1 generation, detailed allocation of capital gains between income and principal, charitable deductions for split-interest trusts, and trusts with more than a handful of beneficiaries push past what TurboTax Business can comfortably handle. There are no professional workpapers and no meaningful audit trail. It’s the right tool for one executor wrapping up a parent’s modest estate, not for ongoing trust administration.

Drake Tax

A practical middle option for small and mid-sized firms that want real fiduciary features without enterprise pricing. Drake supports Form 1041 with grantor trust handling, QBI worksheets, and K-1 export from the fiduciary return into the beneficiary’s 1040 within the same software. The export has limits: state K-1 amounts and beneficiary basis information still need manual entry on the individual return. Federal data transfer alone saves considerable time. Pricing is generally more accessible than ProSeries or CCH Axcess.

Intuit ProSeries

A professional desktop product with a dedicated fiduciary module. Deep DNI logic, strong state compliance, thorough audit workpapers, and solid handling of charitable remainder trusts and complex multi-beneficiary structures. Pricing combines an annual license with per-return state charges, putting the all-in cost well above consumer products. The interface is functional rather than elegant, and the learning curve assumes professional tax preparation experience.

CCH Axcess Tax

Wolters Kluwer’s cloud platform. Multiple preparers and reviewers can work in the return at once, which is a real workflow advantage for firms. It supports multi-state filing, automated K-1 distribution through secure portals, and integration with other CCH products. Volume-based subscription pricing gives mid-sized firms flexibility to scale with seasonal demand. CCH Trust US is a separate product aimed at institutional filers that need batch processing and direct custodial data imports.

Thomson Reuters ONESOURCE

The top-tier choice for large accounting firms and institutional trust departments. ONESOURCE integrates fiduciary tax compliance with trust accounting, asset management, and reconciliation of custodial statements. It handles the most complex multi-jurisdictional structures and specialized forms including Form 5227 for split-interest trusts. Enterprise pricing sits at the top of the market. Without significant volume of complex returns, the investment doesn’t pay back.

Features That Actually Separate the Products

Not every feature matters for every filer, but a handful genuinely distinguish useful tools from frustrating ones.

Automated DNI Calculation

Non-negotiable. The software has to track income, deductions, and capital gains allocated between the income and principal layers, then compute DNI correctly on Schedule B. Capital gains are where weaker programs stumble. Gains allocated to principal under the trust’s governing instrument are generally taxed at the trust level and excluded from DNI, but if the trustee allocates gains to income or actually distributes them, those gains get pulled into DNI and flow through on the K-1s.¹ Getting this wrong is among the most common errors on fiduciary returns.

The 65-Day Election

Under IRC Section 663(b), a trustee can elect to treat distributions made within 65 days after the close of the tax year as if they were made during the tax year. For a calendar-year trust, distributions made by early March can reduce the prior year’s trust-level tax. Given the 37% rate at $16,000, shifting income to beneficiaries in lower brackets saves real money. Good software tracks this election and adjusts DNI accordingly. Note that filing an extension does not extend the 65-day window; it runs from the close of the tax year, not from the filing deadline.

Schedule K-1 Generation and Export

Every product generates the beneficiary K-1s reporting each beneficiary’s share of income, deductions, and credits.⁴ For firms preparing both the 1041 and the beneficiaries’ 1040s, direct K-1 export saves meaningful data entry. Just be aware that state K-1 amounts often still require manual entry even when federal data flows cleanly.

Multi-State Filing

Trusts easily trigger tax in multiple states: the trust may be administered in one, the trustee lives in another, beneficiaries scatter across several more, and the investments generate income in still others. The software has to compute state credits and produce nonresident state returns. Several states also require their own state-specific K-1s. Basic products can’t handle this cleanly.

Cost Basis Tracking

Trusts holding securities need accurate basis tracking, especially for inherited assets that receive a stepped-up basis. The software has to reconcile brokerage statements and compute gains and losses for Form 8949.⁵ Executors also need to know about Form 8971, which reports basis information to beneficiaries and the IRS. Form 8971 must be filed on paper; it cannot be e-filed.⁶

Electronic Filing

Most products e-file federal Form 1041 and its schedules. Preparers expecting to file 11 or more covered returns (including Form 1041) in a calendar year are “specified tax return preparers” and must e-file.⁷ State e-file coverage varies. Most professional products cover 40 or more states; individual trustee products may be more limited.

Foreign Trust Reporting Is Often a Separate Problem

A U.S. person treated as the owner of any part of a foreign trust must file Form 3520, even in years with no transactions.⁸ Form 3520 also applies to a U.S. person who receives more than $100,000 in gifts or bequests from a nonresident alien or foreign estate. Penalties are severe, often 35% of the reportable amount, and enforcement has intensified. Before you commit to any software, check whether your trust has foreign trustees, foreign-sourced assets, or foreign beneficiaries. Most consumer products don’t support Form 3520 at all, and some professional platforms treat it as an add-on module.

Deadlines Your Software Has to Handle

Calendar-year trusts and estates file Form 1041 by April 15 of the following year. Fiscal-year entities file by the 15th day of the fourth month after year-end.³ Missing the deadline triggers a failure-to-file penalty of 5% of the unpaid tax per month, up to 25%.⁹

Form 7004 grants an automatic five-and-a-half-month extension of the filing deadline.¹⁰ It doesn’t extend the payment deadline: interest and late-payment penalties keep accruing on unpaid balances from the original due date. Any serious fiduciary product supports e-filing Form 7004, and most professional platforms do.
