Professional tax preparer software

For an accountant filing tax returns for multiple clients, my top recommendation is to compare Drake Tax, Intuit Lacerte, and Thomson Reuters UltraTax CS first. They are established professional tax preparation platforms, but the best choice depends on your client volume, the complexity of your returns, and your budget.

The latest 2026 survey from The Tax Adviser and the Journal of Accountancy, based on 1,808 tax practitioners preparing 2025 returns, ranked UltraTax CS first in usage, followed by Lacerte and Drake Tax. Drake Tax and Lacerte tied for the highest average overall rating among the major products, at 4.4 out of 5.www.thetaxadviser.com+1

Quick comparison

These are recommendations by use case, not a universal ranking. Actual costs depend on the tax year, number of returns, state modules, add-ons, and number of users.

How I would choose for your practice

Before purchasing, compare these five things:

• Return mix: Form 1040 only, or also 1120, 1120-S, 1065, 1041, and other entity returns?
• Annual volume: How many returns do you file in a typical year?
• Cost: Compare your estimated total annual cost, including e-filing, state returns, additional business returns, and workflow tools.
• Workflow: Do you need client portals, document scanning, e-signatures, bookkeeping integration, and staff review?
• Security and support: Check access controls, multifactor authentication, backup procedures, data protection, and support availability during filing season.

To help narrow down the ideal match for your practice, let me know:

• Do you prefer a cloud-based (browser) platform or a local desktop installation?
• What is the mix of your client base (mostly 1040 individual returns vs. heavy corporate/partnership/fiduciary)?

For an accounting professional preparing tax returns for paying clients, I’d focus on professional tax preparation software rather than consumer tax-filing products. The best choice depends on your client mix, return volume, complexity, team size, and whether you prefer desktop or cloud-based software.

For the 2026 tax software landscape, the main options worth evaluating are Drake Tax, Intuit Lacerte, Intuit ProConnect Tax, Thomson Reuters UltraTax CS, CCH Axcess Tax, and Intuit ProSeries. These products serve different segments of the professional market, from solo preparers to larger CPA firms.cpasoftwarereviews.com+2

How I would compare them

These are broad positioning differences, not a guarantee that one product will be cheapest for your practice. Check current quotes, included state modules, e-filing charges, user licenses, hosting, and support before comparing total costs.cpasoftwarereviews.com+2

What matters before you buy

• Return types: Confirm support for Forms 1040, 1041, 1065, 1120-S, and 1120 as relevant to your clients.
• State and multistate filing: Verify coverage for every state you need, including nonresident returns.
• E-filing: Confirm supported federal and state e-file forms, rejection handling, and electronic signature options.
• Workflow: Look for reviewer permissions, diagnostics, carryforwards, document imports, and client portals.
• Security: Evaluate access controls, encryption, audit logs, backups, and the vendor's support for your firm's data-security and IRS safeguarding obligations.
• Migration: Ask how prior-year returns, depreciation schedules, and carryover data transfer if you are switching providers.

My recommendation

If I were shortlisting software for a new or growing accounting practice, I would start with Drake Tax, Lacerte, and ProConnect Tax. Add UltraTax CS or CCH Axcess Tax if you have a larger team or more demanding review workflows. Consider ProSeries if your practice primarily handles conventional individual returns.

To narrow this down to the best two or three options for your firm, I have one key question:

Approximately how many client tax returns do you prepare each year, and what types do you handle?

1. Annual return volume

Under 100

100–500

501–2,000

Over 2,000

---

2. Main client return types

Individual returns primarily (1040)

Both individual and business

Business and entity returns primarily

Complex, multistate, or high-net-worth returns

---

3. Preferred setup

Desktop software

Cloud-based software

Either; best overall fit
