Alternatives to TurboTax for the Montana FID-3 Fiduciary Income Tax Return

TurboTax is not the best tool for the Montana FID-3 fiduciary income tax return — particularly after the 2024 legislative overhaul that rewrote how Montana fiduciary income is calculated. If you are an executor who purchased TurboTax or H&R Block to handle estate taxes after a death in Montana, here is the short answer: the federal Form 1041 functionality in those products works reasonably well, but the Montana FID-3 state module has lagged behind the 2024 changes. The new Schedule I, the new Worksheet I, and the elimination of the federal tax deduction are Montana-specific changes that generic tax software does not reliably implement. Filing an incorrect FID-3 exposes the executor to penalties, interest, and potential personal liability.

There are three realistic alternatives to relying on TurboTax alone: (1) using TurboTax for the federal 1041 and manually completing the Montana FID-3 with a Montana-specific guide alongside, (2) engaging a Montana CPA who specializes in fiduciary returns, or (3) preparing the FID-3 manually using the Department of Revenue instructions with a Montana estate guide as the framework. The right alternative depends on the estate's complexity, your comfort with tax forms, and whether you need professional sign-off.

Why TurboTax Falls Short for Montana FID-3

TurboTax Business handles federal Form 1041 and produces the federal calculation correctly for most estates. The problem is the Montana state layer. The 2024 overhaul introduced three structural changes that generic software must implement as Montana-specific rules:

Eliminated federal tax deduction. Prior to 2024, Montana fiduciaries could deduct federal income taxes paid, reducing Montana taxable income. This deduction was eliminated. The effect: Montana taxable income for the estate is now meaningfully higher than under prior law for any estate that owed federal tax. Software that has not implemented this change will understate Montana fiduciary tax liability.

Redesigned Schedule I. Montana Schedule I determines the state-specific additions to and subtractions from federal adjusted total income. The 2024 version has different line items, different sequencing, and different calculations than prior-year versions. If the software is populating an older version of Schedule I, the Montana adjustments will be incorrect.

New Worksheet I for beneficiary allocations. Worksheet I allocates Montana additions and subtractions among the estate and each beneficiary in proportion to distributions. This worksheet did not exist in prior-year filings. Software that has not added Worksheet I will produce Schedule K-1 forms with incorrect Montana allocations — affecting each beneficiary's individual Montana tax liability.

The result: TurboTax may produce a Montana FID-3 that looks complete but contains incorrect state tax calculations. An executor who files this return without verifying the Montana-specific adjustments risks understating the estate's tax liability — and becomes personally responsible for the difference plus penalties and interest.

Comparison: Alternatives to TurboTax for Montana FID-3

Alternative 1: Use TurboTax for Federal 1041, Then Complete Montana FID-3 Manually

This is the most practical option for most Montana executors. TurboTax Business or H&R Block Premium & Business reliably handles federal Form 1041. Once the federal return is complete, use the federal adjusted total income figure as the starting point for the Montana FID-3 and complete the state return manually.

What you need alongside the manual approach:

• Current Montana FID-3 instructions from the Department of Revenue (available at revenue.mt.gov)
• The 2024 Schedule I with its new line items and calculations
• Worksheet I for allocating Montana adjustments to beneficiaries
• The current tax rate table: 4.7% on ordinary income under $21,100; 5.9% above; 3.0%–4.1% on net long-term capital gains
• Montana TransAction Portal (TAP) or payment voucher to remit any tax owed

A Montana-specific estate guide that explicitly covers the 2024 FID-3 changes helps this approach significantly. The Department of Revenue instructions are accurate but written for tax professionals who understand the prior system. A plain-English guide that explains what changed and why — and walks through each Schedule I and Worksheet I line — makes the manual completion manageable for an organized executor without a tax background.

Alternative 2: Engage a Montana CPA Who Specializes in Fiduciary Returns

A Montana CPA who handles estate fiduciary returns regularly will have the most accurate version of the FID-3 calculation. This is the right choice for:

• Estates with business income, depreciation, or multiple income streams requiring professional judgment
• Estates where the decedent and surviving spouse previously lived in a community property state — the double step-up in basis calculation under the Uniform Disposition of Community Property Rights at Death Act requires actuarial accuracy
• Any situation where the executor wants a professional to sign off under professional liability

What to know before engaging a Montana CPA for the FID-3:

• Montana removed statutory percentage caps on professional fees in 2019 — billing is based on a "reasonable fee" standard with no ceiling
• A routine FID-3 engagement typically costs $1,500 to $3,000 for a straightforward estate; complex estates exceed this
• The CPA will need the federal Form 1041 data, all estate income documents, and a list of beneficiaries and distribution amounts
• The CPA's scope is typically limited to tax filings — the creditor window, probate pathway, and asset transfer steps are not part of a standard CPA engagement

A Montana estate guide alongside a CPA engagement allows you to handle the non-tax steps independently and bring the CPA in only for the FID-3 and Form 706 portability analysis.

Alternative 3: Montana Legal Services or Free Tax Assistance Programs

Montana Legal Services Association (montanalawhelp.org) provides free legal assistance for low-income Montanans, including some estate-related guidance. The AARP Tax-Aide program provides free tax preparation assistance but typically handles individual returns rather than fiduciary returns.

The limitation of free programs: they serve low-income demographics with straightforward situations. The 2024 FID-3 overhaul and the portability election mechanics for Form 706 require specialized knowledge that volunteer tax assistance programs may not reliably provide.

What Actually Matters More Than the Software Choice

The most consequential errors for Montana executors are not software errors — they are sequence errors:

• Distributing estate assets before the four-month creditor window closes (creates personal liability for the executor)
• Missing the estimated tax payment deadline of April 15 while relying on the six-month filing extension (extension covers filing, not payment)
• Filing the FID-3 without assigning an EIN to the estate (using the decedent's SSN causes administrative problems)
• Missing the Form 706 portability election for a surviving spouse (Montana has no state estate tax but the federal portability benefit is real and time-limited)
• Failing to distribute Schedule K-1 (FID-3) forms to beneficiaries before they file their individual Montana returns

No software product addresses these sequence errors. They are addressed by a comprehensive Montana estate administration guide that covers the full system — from ordering death certificates on Day 1 through closing the estate after the creditor window expires.

The Montana Final Tax & Estate Tax Guide as a TurboTax Supplement

The Montana Final Tax & Estate Tax Guide is designed to work alongside federal tax software, not replace it. Use TurboTax Business to prepare the federal Form 1041. Use the guide's FID-3 Filing Reference — one of seven standalone reference sheets included with the guide — to complete the Montana FID-3 manually with the 2024 overhaul changes applied correctly.

The guide also covers the full Montana estate administration sequence, so the FID-3 is filed in the right order relative to the creditor notice publication, the creditor window, and the final distribution. No software product handles this cross-agency coordination.

Who This Guide Approach Is For

• Executors who bought TurboTax and are now uncertain whether the Montana state module is accurate for 2024
• Personal representatives who want to use software for the federal return but complete the Montana FID-3 manually with a reliable framework
• Surviving spouses managing the estate of a spouse who received Medicaid after age 55 — the Medicaid recovery timeline intersects with the FID-3 timing and must be handled together
• DIY executors handling a straightforward Montana estate who want to avoid both professional fees and the risk of filing incorrect returns

Who Should Use a CPA Instead

• Estates where the decedent owned a business that generated complex income during the administration period
• Estates where the FID-3 requires professional valuation of assets for the Schedule I calculations
• Personal representatives who want a professional to bear liability for the accuracy of the fiduciary return
• Executors managing an estate that may qualify for the community property double step-up in basis under the Uniform Disposition of Community Property Rights at Death Act — this is a CPA-level calculation

Frequently Asked Questions

Does TurboTax handle the Montana FID-3?

TurboTax Business includes a Montana state module, but it has not reliably implemented the 2024 overhaul — specifically the new Schedule I, the new Worksheet I, and the elimination of the federal tax deduction. The federal Form 1041 component is reliable. The Montana FID-3 should be verified manually against the current Department of Revenue instructions.

What is the cheapest way to file Montana FID-3 correctly?

Use TurboTax Business or H&R Block Premium & Business for the federal Form 1041, then complete the Montana FID-3 manually with the current Department of Revenue FID-3 instructions and a Montana-specific estate guide that covers the 2024 changes. This costs less than a CPA engagement and produces a more accurate result than relying on software alone for the Montana state module.

Can H&R Block handle Montana estate taxes?

H&R Block Premium & Business handles federal Form 1041. Its Montana FID-3 module has the same limitations as TurboTax — the 2024 overhaul changes may not be correctly implemented. Use the software for the federal return and verify the Montana calculations manually.

How much does a Montana CPA charge for fiduciary tax returns?

Montana CPAs typically charge $200–$400 per hour for estate tax work. A routine FID-3 engagement for a straightforward estate commonly runs $1,500–$3,000. There is no statutory fee cap — Montana removed percentage-based caps in 2019.

What Montana-specific tax rates apply to estate income?

Ordinary fiduciary income up to $21,100 is taxed at 4.7%. Ordinary income above $21,100 is taxed at 5.9%. Net long-term capital gains are taxed at 3.0% or 4.1% depending on the fiduciary's total non-capital gain taxable income.

Does the estate have to file a Montana return if all assets had beneficiary designations?

If all assets passed via beneficiary designations, Transfer on Death titles, or joint tenancy — and no assets went through the probate estate — the estate may have minimal or no post-death income to report on a FID-3. However, the decedent's final individual income tax return (Form 2) is still required regardless of asset structure.
