Greenback Tax Services vs DIY Filing: Comparison (2026)

Greenback Tax Services is a well-known CPA firm specializing in expat tax preparation. But at $450+ per return, is it worth the cost for H-1B visa holders, or can guided DIY software deliver the same accuracy at a fraction of the price?

What Is Greenback Tax Services?

Greenback Tax Services is a U.S.-based CPA firm that provides full-service tax preparation for Americans abroad and foreign nationals working in the U.S. Founded in 2008, they specialize in expat tax returns and handle a wide range of international tax situations.

Their service model is fully remote. You upload your documents, communicate with an assigned CPA or Enrolled Agent (EA) via email and messaging, and receive a completed tax return for review before filing. The process typically takes 2 to 4 weeks, longer during peak season.

Key characteristics of Greenback include:

• Full-service preparation — A human CPA or EA prepares your entire return. You provide documents, they do the work.
• Expat specialization — They are experienced with FBAR, FATCA, Form 2555 (FEIE), Form 1116 (FTC), and other international forms.
• Fixed pricing (starting at $450) — Simple returns start at $450. Complex returns with multiple international forms, business income, or multi-state filing range from $650 to $1,200 or more.
• Year-round availability — Unlike seasonal preparers, Greenback operates year-round and handles amended returns and late filings.
• Audit support — They offer audit assistance as part of their service package.

Greenback is a legitimate, well-reviewed firm. The question for H-1B visa holders is not whether they are good, but whether the cost is justified for your specific tax situation.

Greenback Pricing vs DIY Software Costs

The cost difference between full-service preparation and DIY software is substantial. Here is how the options compare:

At $450 for a simple return, Greenback costs 18 times more than H1B TaxFile ($49.99). For a complex return at $650 to $1,200, the difference grows to 26 to 48 times. The question is whether that premium buys you meaningfully better accuracy for a standard H-1B return.

What You Get with Full-Service Expat Tax Filing

Full-service preparation from Greenback or a comparable expat CPA firm provides several advantages that DIY software does not:

• Professional judgment — A CPA can evaluate ambiguous situations, such as whether to claim a treaty benefit or how to handle a dual-status year, and make professional recommendations based on your specific circumstances.
• Error backstop — If the CPA makes an error, the firm carries professional liability insurance. Some firms cover penalties and interest caused by their mistakes.
• Audit representation — If the IRS audits your return, a full-service firm can represent you or assist with the response. This can be worth thousands of dollars if it happens.
• Complex scenario handling — For situations involving business income from multiple countries, trust distributions, real estate sales in India, or prior-year compliance issues, a CPA can navigate complexities that no software currently handles.
• Peace of mind — Some filers prefer knowing a professional reviewed everything. The psychological comfort of delegating tax preparation has real value, especially in the first few years of U.S. filing.

These benefits are real. However, they matter most for complex tax situations. For the standard H-1B return with W-2 income, RSUs, and Indian accounts, the question is whether a $450+ service provides $425 more value than $49.99 software.

When DIY Filing Makes More Sense

For the majority of H-1B visa holders, the tax situation is well-defined and follows predictable patterns. If your return includes the following elements and nothing beyond them, DIY software is equally accurate at a fraction of the cost:

• W-2 employment income — One or two employers, straightforward wages, bonuses, and equity compensation.
• RSU and ESPP sales — Stock sales with cost basis correction. Specialized software handles this automatically with RSU cost basis adjustment.
• Indian bank accounts (NRE, NRO) — Interest income reporting on Schedule B, with FBAR and FATCA threshold calculations.
• Indian EPF and PPF — Interest reporting and withdrawal handling. See our guide on EPF/PPF U.S. tax treatment.
• Foreign tax credits — TDS paid on Indian interest and dividends, claimed on Form 1116.
• Indian mutual funds (PFICs) — Mark-to-Market election reporting on Form 8621.
• Standard deductions and credits — Child Tax Credit, education credits, HSA, 401(k) contributions.

This profile describes the vast majority of Indian H-1B holders working in the U.S. tech industry. The tax rules for each of these items are well-established, and specialized software applies them consistently every time. A CPA would follow the same rules and arrive at the same numbers.

Accuracy Comparison: CPA vs Guided Software

A common concern with DIY filing is accuracy. Will software produce the same result as a trained CPA? For standard H-1B returns, the answer is yes, and here is why:

• Tax law is deterministic — For most line items on Form 1040 and its schedules, there is exactly one correct answer given a set of inputs. The tax brackets, deduction amounts, credit phase-outs, and form instructions are published by the IRS. Both software and CPAs follow the same instructions.
• Software eliminates arithmetic errors — CPAs are human and can make transcription or calculation mistakes. Software computes every line automatically using the IRS-published formulas. H1B TaxFile uses Big.js for precise decimal arithmetic, eliminating rounding errors.
• Specialized software knows H-1B rules — General CPAs (even experienced ones) may not be current on PFIC mark-to-market elections, the latest FATCA thresholds, or the specific cost basis adjustment rules for RSUs. H-1B-specific software encodes these rules directly.
• CPAs add value in gray areas — Where a CPA outperforms software is in judgment calls: whether to take a treaty position, how aggressively to deduct home office expenses, or whether to file an amended return for a prior-year issue. If your situation does not involve gray areas, this advantage does not apply.

The IRS does not distinguish between CPA-prepared and software-prepared returns. Both are held to the same standard. For standard H-1B situations, software and CPA accuracy are functionally identical.

The Middle Ground: Affordable Software with H-1B Expertise

The tax preparation market has traditionally offered two extremes for H-1B filers: cheap generic software that misses international forms, or expensive CPA services that handle everything but cost $450+. The middle ground is specialized H-1B tax software that combines the affordability of DIY with the international form coverage of a CPA.

H1B TaxFile occupies this middle ground. At $49.99, it costs less than TurboTax Deluxe ($69) while providing comprehensive H-1B coverage:

• 14 IRS forms and 7 schedules, including all H-1B-specific forms
• Automatic RSU and ESPP cost basis correction with Form 8949 generation
• FATCA Form 8938 with threshold calculations for all filing statuses
• PFIC Form 8621 with Mark-to-Market election support for Indian mutual funds
• Form 1116 foreign tax credit with multi-category (passive and general) support
• INR-to-USD conversion using IRS-published average exchange rates
• EPF/PPF interest reporting with Schedule B integration
• Form 8833 treaty disclosure guidance for India-U.S. tax treaty positions

For the standard H-1B return, this approach delivers CPA-level form coverage and accuracy at 5% of the cost. The savings compound every year, and the output — a complete, printable PDF tax return package — is ready to review, sign, and mail.

If your situation genuinely requires professional judgment (business income, multi-country residency, audit response), by all means hire a CPA. But if you are a W-2 employee with Indian accounts and RSUs, specialized software is the smarter financial choice.
