A financial advisor can help you align your tax strategy with your overall financial goals.

Methodology and Data

We identified the software below through exhaustive research and analysis of the of the tax software market. They are listed in an order that’s in direct correlation with their individual composite score based on our methodology, which includes consumer ratings from multiple popular online app stores, and the cost to use each individual software.

1. Cash App Taxes

Formerly known as Credit Karma, Cash App Taxes stands out in the crowded tax software market for one compelling reason: it provides  completely free tax software. 

Many of Cash App Taxes’ competitors lure users in with a free tier, only to charge later for certain forms or state filings. Instead, Cash App Taxes truly costs $0 for both federal and state returns. For budget-conscious taxpayers, especially those with straightforward filing needs, this can be a major advantage, eliminating the sticker shock that often comes at the final submission screen.

Because Cash App Taxes is integrated directly into the Cash App ecosystem, setup is quick for existing users. Importing last year’s return is straightforward, and the step-by-step guidance is clear without feeling overwhelming. 

That said, its customer support options are limited compared to premium tax software, relying heavily on self-help resources and online FAQs. For confident filers, this may not be a deal-breaker, but first-time or uncertain users might feel the lack of direct support.

Cash App Taxes is best suited for individuals who want a truly free filing experience without sacrificing a clean interface and solid basic features. If your tax situation is relatively simple and you are comfortable navigating tax questions without extensive hand-holding, this could be an ideal solution. However, filers with more complex circumstances may find that paying for a more comprehensive tax platform may be well worth the investment.

2. TaxCaddy

TaxCaddy takes a different approach from traditional tax software, focusing less on self-preparation and more on collaboration with your tax advisor. 

The platform serves as a secure digital hub for gathering, storing and sharing your tax documents in one place. Instead of manually emailing files or struggling through 1040 paper forms, you can upload W-2s, 1099s and receipts directly to TaxCaddy, where your CPA or tax preparer can access them instantly.

TaxCaddy offers a free version with core features like document uploads, e-signatures and mobile access. Some accounting firms provide premium versions at no cost to clients, while others may charge for advanced tools like unlimited cloud storage or integrated payment options. For individuals who already work with a tax professional, the platform’s efficiency and convenience often justify any additional expense, especially compared to the time saved in organizing paperwork.

TaxCaddy is best for taxpayers who work with a CPA or enrolled agent and want to simplify the document exchange process. It is not a DIY tax filing solution; if you want to prepare and file your tax return entirely on your own, this is not the right fit. 

However, if your goal is to reduce paperwork headaches and securely centralize tax information for professional preparation, TaxCaddy excels.

3. TaxSlayer

TaxSlayer believes in flexibility with four plans to choose from, depending on your experience level and tax needs.

Pricing for online filing varies, with a free option available for basic needs. If you require more advanced services, you can choose from the Deluxe, Premium or Self-Employed options based on your specific filing needs. 

H&R Block Plans

While many of the best online tax software winners offer online access to experts, H&R Block understands that sometimes, it is just nice to talk with someone in person. If you prefer to file your return by working face-to-face with a tax professional, you simply need to visit an H&R Block store. 

This makes H&R Block a great option for people with complicated tax situations, because when you file in person, you get an accuracy guarantee and audit support. You may also consider filing at a store if your tax situation has changed greatly from last year to this year.

H&R Block is ideal for filers who value flexibility, whether they want to file completely online, get live help online or receive in-person support from a local office. Overall, it is a solid choice for both straightforward and complex returns, making it a dependable option for individuals and families who want a trusted, full-service tax partner.

5. TurboTax

TurboTax remains one of the best online tax software platforms, thanks to its polished interface, comprehensive features and wide-ranging support for different tax situations. While not the cheapest option, TurboTax is known for delivering value through its ease of use and depth of capabilities.

It offers a free edition for basic federal returns, with paid packages starting around $39 for Deluxe and increasing for more complex needs like investments, self-employment or rental property income. State filings cost extra, and add-ons like live CPA guidance raise the price further. 

Turbo Tax Plans

TurboTax supports a wide range of scenarios, from simple wage income to complex returns with multiple states, foreign income or small business deductions. Built-in calculators help maximize tax credits and deductions, while final review checks add an extra layer of confidence.

The Where’s My Refund? feature allows filers to track the progress of their refund just 24 hours after submitting a return. It also supports secure tax payments via IRS Direct Pay or the Electronic Federal Tax Payment System (EFTPS). 

For those seeking free filing help, IRS2Go can connect users to Volunteer Income Tax Assistance (VITA) and Tax Counseling for the Elderly (TCE) programs, which offer in-person aid to eligible taxpayers. The app is available in both English and Spanish, with accessibility features that make it easy to use across devices.

IRS2Go is best for taxpayers who want a simple but secure way to monitor their refund status, make payments and access IRS services without visiting a website or office. While it is not a replacement for tax preparation software, it is still an excellent add-on tool to help you stay informed and in control throughout the filing process.

Designed for budget-conscious filers, TaxAct aims to deliver many of the same features as pricier competitors without the higher price tag.
