Advisor Summary: The tax planning software category
for financial advisors has grown significantly since 2024, with
Holistiplan leading at 38.92% market share (T3/Inside Information 2026
Survey). The key question for advisors evaluating tools in 2026 is
whether tax planning should live in a standalone tool or inside the
financial planning platform. Standalone tools like Holistiplan offer
speed and simplicity for current-year analysis. Integrated platforms
like Income Lab Pro connect tax planning to the client’s actual spending
plan, Social Security timing, and IRMAA brackets. This guide compares 8
tools across features, pricing, and use case fit.
A 67-year-old client walks into your office with a question: “My CPA
says I should do a $150,000 Roth conversion this year. Should I?”
You know the answer depends on at least six variables that the CPA
probably did not consider together: the client’s Social Security
claiming age, their current IRMAA bracket, the two-year lookback effect
on Medicare premiums, their spending plan for the next three years,
whether they will cross any state tax thresholds, and how this
conversion interacts with their RMD trajectory starting at 73.
Your current planning software shows a probability percentage. Your
tax tool shows last year’s brackets. Neither one shows you how a
$150,000 conversion in 2026 cascades through Medicare premiums in 2028,
Social Security taxation in 2027, and spending capacity adjustments over
the next decade.
That gap is why the tax planning software category is expanding.
Advisors need tools that connect the tax decision to the full retirement
plan, not tools that analyze tax returns in isolation.

What to Look For in Tax Planning Software
Before comparing specific tools, clarify what you actually need. Tax
planning software for financial advisors falls into two categories:
standalone tax analysis tools and tax planning
integrated into a broader platform. Neither is inherently
better. The right choice depends on how central tax planning is to your
client conversations and whether you also offer clients longer-view
financial planning.
Eight capabilities that
matter
-
Document upload. Can you upload a 1040 or other
tax documents and get immediate analysis? This determines how fast you
can start a tax conversation. -
Marginal rate analysis. Does the tool show
effective marginal rates, including hidden interactions like Social
Security taxation thresholds, NIIT cliffs, and IRMAA bracket jumps? A
client in the 22% bracket may face an effective marginal rate above 40%
once these interactions stack. -
Roth conversion modeling. Can you model multiple
conversion strategies and compare their tax impact over 5, 10, or 20
years? Single-year Roth analysis misses the multi-year dynamics that
determine whether a conversion actually saves money. -
IRMAA integration. Does the tool account for
Medicare IRMAA surcharges in its Roth conversion and distribution
analysis? Medicare uses a two-year MAGI lookback, so a conversion that
saves $3,000 in income tax today but triggers $2,297 in annual IRMAA
surcharges for a couple two years later (per CMS 2026 Tier 1 premium
tables) is a net loss. For clients age 63 and older, this is not
optional. -
Multi-year projections. Can the tool project
taxes forward using current assumptions and known future policy changes
(including at the state level), or is it limited to current-year and
historical analysis? -
Estate planning. Does the tool address inherited
IRA distribution strategies, beneficiary tax optimization, and gift
vs. step-up analysis? -
Income planning integration. Does tax analysis
connect to the client’s retirement spending plan, withdrawal sequencing,
and Social Security strategy? Or does it operate in isolation? -
Pricing transparency. Is pricing published, or
do you need to sit through a demo to learn what it costs?
The 2026 Tax Planning Software
Landscape
The T3/Inside Information Advisor Software Survey 2026 (2,906
respondents) provides the most current picture of market share and
satisfaction in the tax planning category:
| Tool | Market Share | Satisfaction Rating | Category |
|---|---|---|---|
| Holistiplan | 38.92% | 9.1/10 | Standalone tax analysis |
| Tax Status | 9.22% | N/A | Tax return monitoring |
| RightCapital | 0.96% | 7.11/10 | Planning platform with tax module |
| Income Lab | Write-in mentions | N/A (new category entry) | Planning platform with integrated tax |
Source: T3/Inside Information Software Survey 2026
The category is consolidating around Holistiplan while fragmenting at
the edges. Per the T3 2026 Survey, Tax Status grew from 1.46% to 9.22%
market share in a single year, the fastest growth of almost any tool in
any category. New AI-powered entrants like Altruist’s Hazel (launched
February 2026) are adding competitive pressure. And planning platforms
are building tax capabilities into their core products rather than
relying on integrations.
The most important trend: tax planning is moving from
standalone tools into planning platforms. The question is no
longer “Which tax tool should I buy?” but “Should my tax analysis live
inside my planning software?”

Holistiplan: The Category
Leader
Best for: Advisors who need fast 1040 analysis at
scale, tax prep letter generation, and a simple workflow that
supplements their existing planning platform.
According to the T3/Inside Information 2026 Survey (2,906
respondents), Holistiplan holds 38.92% market share and a 9.1/10
satisfaction rating in the tax planning category. The core value
proposition is speed: per Holistiplan’s product documentation
(holistiplan.com, April 2026), upload a 100+ page tax return and get a
structured analysis in under 60 seconds. That speed transformed how
advisors approach tax planning. Before Holistiplan, tax review was a
once-a-year project. After Holistiplan, it became a routine part of
client meetings.
Strengths: – OCR scanning speed (45-60 seconds for a
full return) – Tax prep letters for CPA coordination (genuine time
saver) – Expanding into insurance planning (P&C coverage analysis)
and estate planning (waitlist) – Enterprise-grade: SOC 2 Type II, SSO,
partners with 9 of the top 15 RIAs – Association discounts (NAPFA, ACP,
Garrett Planning Network) – 7-day free trial, no demo required
Limitations: – Analysis starts from historical tax
returns, not forward-looking plan data – No connection to the client’s
retirement income plan, Social Security strategy, or spending
adjustments – Multi-year projections require manual assumption input,
with limitations on what can be modeled, disconnected from any planning
model – No guardrails-based spending analysis – No Social Security
optimization – Premium features (state tax, Roth projections, tax prep
letters) require the higher tier
Pricing: Basic Tax starts at $749/year (30
households). Premium Tax starts at $1,499/year (30 households). Scales
with household count up to 750; contact sales above that.

Income
Lab Pro with Penny: Tax Planning Inside the Retirement Plan
Best for: Advisors whose tax planning conversation
is inseparable from the retirement income conversation. Practices that
want one platform for tax, Social Security, Medicare/IRMAA, estate, and
income planning, all using the same client data.
According to the T3/Inside Information Advisor Software Survey,
Income Lab has been the #1 retirement distribution planning tool by
market share for four consecutive years (2023-2026), with a 4.15% share,
the largest in the category. With the launch of Penny in April 2026,
Income Lab Pro added a suite of structured tax planning tools that
connect directly to the client’s retirement income plan.
The key differentiator is plan integration. When you run a Roth
conversion analysis in Income Lab, it automatically accounts for the
client’s Social Security claiming strategy, IRMAA bracket positioning,
guardrails-based spending adjustments, and withdrawal sequencing across
all account types. You do not have to imperfectly recreate assumptions
from a separate tool.
Structured tax tools include: – Marginal Rate
Explorer (multi-year, connected to plan projections) – Roth Conversion
analyzer (20 simultaneous strategies with bracket management) – Tax
Summary Report – W-4 Analyzer – NUA Analysis – IRMAA Appeal Calculator
(generates SSA-44 filing guidance and instructions; does not file the
appeal itself)
Additional capabilities beyond tax: – Social
Security Optimizer (9,000+ claiming combinations for couples, 8.60 T3
rating, highest in category) – Guardrails-based spending capacity
(monthly recalculation) – Estate planning tools (Inherited IRA
optimizer, Beneficiary optimizer, Gift vs Step-Up, Charitable Giving) –
Medicare Roadmap (enrollment timelines, IEP dates, cost projections) –
Practice Intelligence (scans entire book for planning opportunities) –
Document upload without building a full plan first
Strengths: – Every tax analysis reflects the actual
retirement plan (no assumption duplication) – IRMAA bracket management
with two-year MAGI lookback projections – 20 distribution strategies
compared simultaneously in Tax Lab – Can upload a 1040 and get analysis
without an existing Income Lab plan – Tax calculations use deterministic
engines, not AI. AI handles classification and explanation; math is
verifiable.
Limitations: – No tax prep letter generation
(available as a workaround through Penny’s AI chat, but not the
structured feature Holistiplan offers) – Deeper tool; Use of full
financial planning has steeper learning curve than Holistiplan’s
upload-and-go workflow – Penny (including all tax tools) requires Pro
tier at $299/month ($2,990/year); not available on Core
Pricing: Core at $199/month ($1,990/year) includes
Tax Lab, Social Security Optimizer, guardrails, and retirement
distribution. Pro at $299/month ($2,990/year) adds Penny with all
structured tax, Medicare, and estate tools. Per-advisor pricing; flat
regardless of client count. (incomelaboratory.com, April 2026)
TaxPlannerPro:
Multi-Year Tax Projection Specialist
Best for: Advisors who need a dedicated multi-year
tax projection engine as a standalone deliverable for clients.
TaxPlannerPro focuses on detailed year-by-year tax forecasting. The
tool models federal and state income taxes over extended timeframes,
allowing advisors to visualize how different strategies (Roth
conversions, income timing, retirement account distributions) play out
across decades.
Strengths: – Deep multi-year tax projections –
Detailed Roth conversion analysis across extended timeframes –
Purpose-built for tax modeling
Limitations: – Limited integration with broader
financial planning platforms – No connection to dynamic retirement
income planning – No document upload or 1040 scanning – No Social
Security optimization or IRMAA analysis
Covisum Tax
Clarity: Marginal Rate Visualization
Best for: Advisors already using Covisum’s suite
(Social Security Timing, Income InSight) who want tax analysis that
connects to those tools.
Covisum Tax Clarity visualizes hidden effective marginal income tax
rates, revealing how tax bracket interactions, Social Security taxation
thresholds, and other cliffs create effective rates far above the stated
bracket. It is part of the broader Covisum suite, which adds Social
Security Timing, Income InSight (retirement income planning), and
SmartRisk (portfolio risk analysis).
Strengths: – Clear visualization of effective
marginal rates and hidden cliffs – Integration with Covisum’s Social
Security Timing tool – Part of a broader retirement-focused suite –
Founded by a practicing advisor (Joe Elsasser, CFP)
Limitations: – Limited state tax modeling – No
business-owner deduction handling – No document upload or 1040 scanning
– Income InSight is scenario-based, not dynamically updated – No
guardrails-based spending methodology – No AI-powered features
Pricing: Tax Clarity is part of the Covisum Suite at
approximately $2,800/year for the full bundle. Individual tool pricing
varies. (covisum.com, February 2026)
How Tax Planning
Connects to Income Planning
Here is the question most tool comparisons miss: does your tax
planning tool talk to your income planning tool?
For a client with $1.2M in traditional IRAs planning to claim Social
Security at 67, a Roth conversion analysis that does not account for
their spending plan is incomplete. Consider the cascading effects:
The conversion amount affects MAGI. A $100,000
conversion in 2026 pushes MAGI above the IRMAA Tier 1 threshold
($218,000 for joint filers), adding $2,297 in annual Medicare Part B and
D surcharges for the couple starting in 2028. Over three years of
Medicare eligibility before the MAGI drops, that is $6,891 in additional
premiums.
The conversion affects Social Security taxation.
Combined income (AGI + nontaxable interest + half of SS benefits) above
$44,000 for joint filers subjects up to 85% of Social Security benefits
to income tax. A large conversion in the same year as Social Security
income can push the effective marginal rate above 40%.
The conversion affects withdrawal sequencing. Paying
conversion taxes from the IRA itself (rather than taxable accounts)
reduces the conversion’s long-term value. The optimal funding source
depends on the client’s full account structure and spending needs.
The conversion affects guardrail thresholds. If the
client’s portfolio balance drops because conversion taxes were paid from
investment accounts, spending capacity may temporarily decrease,
requiring a guardrails adjustment the client needs to understand.
Standalone tax tools model the conversion. Integrated platforms model
the conversion plus every downstream effect on the actual retirement
plan. For clients in or near retirement, where these interactions
compound annually, the difference matters.
Second scenario: the IRMAA
trap
A 65-year-old couple on Medicare with $180,000 in combined income
sits comfortably below the IRMAA Tier 1 threshold ($218,000 for joint
filers). Their advisor recommends a $170,000 Roth conversion, bringing
2026 MAGI to $350,000. Per CMS 2026 IRMAA brackets, this pushes them
into Tier 3 in 2028, adding $9,240 in combined annual Part B and D
surcharges for the couple ($4,620 per person). The Roth conversion saves
roughly $37,400 in income tax (22% bracket). Over three years of higher
IRMAA premiums, the surcharges total $27,744. Net benefit: $9,656
instead of $37,400. A tool that does not model the IRMAA interaction
overstates the conversion benefit by 74%.
Which Tool Fits Your
Practice
If
tax planning supplements your existing planning platform
Choose Holistiplan. Its speed and simplicity make it
the best option for advisors who use a comprehensive planning tool
(eMoney, MoneyGuidePro, RightCapital) for the core financial plan and
want fast tax return analysis as an overlay. Tax prep letters are a
genuine differentiator for CPA coordination.
If
tax planning is the center of your retirement conversation
Choose Income Lab Pro. When the retirement income
question and the tax question are the same question (“How much can I
spend, and what is the most tax-efficient way to get there?”), you need
a platform where those analyses share the same data. Income Lab Pro with
Penny connects Roth conversion analysis, IRMAA management, Social
Security optimization, and spending capacity in a single model.
If you need a
dedicated tax projection engine
Choose TaxPlannerPro. For advisors who deliver
standalone multi-year tax projections as a primary service offering, a
purpose-built projection tool makes sense.
If you are already
in the Covisum ecosystem
Choose Covisum Tax Clarity. If you use Social
Security Timing and Income InSight, adding Tax Clarity keeps your tools
in the same family with shared data.
If your clients custody at
Altruist
Consider Altruist Hazel. Hazel sees account-level
detail (cost basis, holdings, transactions) for Altruist accounts. It is
limited to Altruist custodial data and does not connect to a broader
financial plan, but the depth of custodial data access is a real
advantage for Altruist-only practices.
