The Best Tax Reporting Software for Third-Party Administrators of 2026

Third-party administrators need more than a place to submit forms. In this comparison, "tax reporting software" means year-end wage and information reporting tools that help PEOs, reporting agents, and benefits administrators organize client and EIN data and move W-2, 1099, and 1095 filings through trackable workflows.

In September 2026, we evaluated seven live platforms using published product details, pricing, support information, and available third-party reviews; factor scores use a 10-point scale, and weighted totals are shown on the same 10-point scale. The comparison focuses on the multi-client work TPAs manage before, during, and after submission.

Comparison Criteria

• Multi-client and team workflow (22%): Client and EIN separation, user permissions, team management, and centralized oversight.
• Data imports and integrations (18%): Bulk uploads, reusable templates, direct integrations, and support for varied source data.
• Complete filing and delivery (17%): Federal filing, state reporting, recipient e-delivery, and print-and-mail coverage.
• TPA-relevant form coverage (14%): W-2, 1099, 1095/ACA, corrections, and relevant quarterly or specialty forms.
• Validation and filing visibility (12%): TIN matching, error checks, correction workflows, and acceptance or rejection statuses.
• Live support access (9%): Access to human help during deadline-sensitive filing periods.
• Pricing clarity and inclusions (8%): Whether published pricing shows the full cost of filing, delivery, state services, and add-ons.

In the table below, each platform is scored against these seven factors. The company-by-company analysis then explains where each option fits and what TPAs should verify before committing.

Yearli, for complete multi-client filing

Yearli is designed for PEOs, reporting agents, and benefits administrators that file for multiple businesses. Yearli Performance supports high-volume, multi-client filing and includes W-2, 1099, and 1095 filing, unlimited TIN matching, and phone support. Yearli Premier adds team management, role-based access, advanced reporting, prior-year filing, and multi-user licenses. TPAs can enter data manually, use a generic template, or draw from more than 30 integrations. Those paths matter when client files arrive from several payroll, HR, or accounting systems and need to be standardized before submission.

The main distinction is the ability to keep federal filing, state reporting, and recipient delivery in the same workflow. Yearli Core and Yearli Performance bundle those services into per-form pricing, while Yearli Premier offers bundled or à la carte filing. That structure makes Yearli a stronger fit when a TPA wants fewer vendor handoffs and a clearer record of what was submitted, accepted, rejected, mailed, or posted. Buyers should still model the correct plan, filing volume, and optional features. Team permissions belong to Yearli Premier, while unlimited TIN matching and phone support belong to Yearli Performance and Yearli Premier.

• Location: Grand Rapids, Michigan
• Price Range: Yearli Premier is $799/year plus filing fees; custom pricing is available
• Services Offered: W-2, 1099, 1095/ACA, federal filing, state reporting, recipient delivery, TIN matching, integrations, team management, and reporting
• Year Founded: 2014 for the Yearli platform; Greatland Corporation was founded in 1974
• Review Score: 4.8/5 from 81,689 Shopper Approved reviews as of 09/2026

TaxZerone, for broad form coverage

TaxZerone supports a wider form set than most platforms in this comparison. Its public product pages cover W-2 and W-2C, the full 1099 series, 1095/ACA, 94X employment forms, 1098, 5498, 1042-S, and several business and exempt-organization returns. For TPAs that support clients with mixed year-end and quarterly obligations, that breadth can reduce the need to move specialized filings into a separate tool. The platform also publishes multi-user roles, a centralized e-file center, bulk uploads, form history, IRS validation, free retransmission after rejection, and real-time filing updates.

TaxZerone's ACA bulk-upload process is particularly relevant for benefits administrators. It accepts XLSX, XLS, and CSV files, validates records before transmission, generates 1094 transmittals, allows corrected re-uploads, and tracks submissions from in-progress through accepted or rejected. The trade-off is that complete delivery is assembled from multiple charges. Federal e-file, direct state reporting, print and mail, and e-delivery can be separate line items. Its second-place result comes from strong form coverage, imports, and validation rather than an all-inclusive delivery model. TPAs should price a representative W-2, 1099, and ACA client mix before deciding whether the broad library offsets the added billing complexity.

• Location: Not publicly listed
• Price Range: As of 09/2026, information-return e-file rates vary by form and volume; state filing and recipient delivery may cost extra
• Services Offered: W-2, 1099, 1095/ACA, 94X, state filing, bulk uploads, multi-user roles, validation, corrections, and recipient delivery
• Year Founded: Not publicly listed
• Review Score: 4.2/5 from 8 Trustpilot reviews as of 09/2026

1099 Pro Cloud, for validation-heavy workflow

1099 Pro Cloud is suited to organizations that manage many payers and prioritize recipient-data validation. Every cloud subscription supports unlimited users and payers, import templates, bulk TIN matching on import, real-time TIN validation, correction management, and Combined Federal/State Filing for eligible forms. Its library includes W-2, the 1099 series, 1098, 1042 and 1042-S, 3921, 3922, and W-2G. Corrections are included without counting as another form, which can simplify budgeting when a client sends revised information after initial submission.

TPAs should pay close attention to product boundaries. The standard cloud product does not list 1095/ACA forms, and direct state reporting for W-2 and 1099-NEC is a paid add-on. State reconciliation forms are not supported. Published plans separate e-file-only service from print-and-mail and e-delivery packages, while enterprise features use custom pricing. Those limits explain why 1099 Pro Cloud sits behind TaxZerone despite its stronger TIN controls. It is a stronger fit when name/TIN verification, correction handling, and repeatable payer imports carry more weight than ACA reporting or bundled delivery. A TPA serving benefits-administration clients should confirm whether another Sovos product is required for ACA work.

• Location: Wilmington, Massachusetts, through parent company Sovos
• Price Range: As of 09/2026, published cloud subscriptions start at $449 per year; printing, e-delivery, state reporting, and enterprise services vary by plan
• Services Offered: W-2, 1099, 1098, 1042/1042-S, imports, TIN matching, corrections, state filing options, print and mail, and e-delivery
• Year Founded: 1989
• Review Score: 4.1/5 from 8 Capterra reviews as of 09/2026

E-File Magic, for flexible multi-filer imports

E-File Magic lets one account hold unlimited filers, recipients, and users, which gives accounting and service-provider teams a workable base for multi-client filing. Data can move in through QuickBooks Desktop, QuickBooks Online, Xero, or an Excel template. E-file, electronic recipient delivery, encrypted PDFs, and Combined Federal/State Filing are included, while print and mail, bulk TIN matching, and certain state data files are optional. The platform also publishes phone and email contacts, giving filers a direct path to human assistance.

The important limitation for TPAs is form coverage. E-File Magic handles a broad information-return library, including 1099, 1098, 5498, 1042-S, W-2G, and W-9, but it does not publish W-2 or 1095/ACA support. That makes it a practical fit for administrators whose client work is concentrated in contractor, retirement, mortgage, or related information returns. It is less suitable for PEOs or benefits administrators that need employee wage and ACA reporting in the same platform. Pricing is generated through a calculator rather than a simple public rate table, so a TPA should test several representative orders and include optional TIN matching, direct-state needs, and print-and-mail volume.

• Location: Portland, Oregon
• Price Range: As of 09/2026, pricing is calculator-based; e-file and e-delivery are included, while print and mail and TIN matching cost extra
• Services Offered: 1099, 1098, 5498, 1042-S, W-2G, imports, e-delivery, print and mail, TIN matching, and state data services
• Year Founded: Not publicly listed
• Review Score: 4.9/5 from 2,105 Trustpilot reviews as of 09/2026

1099FIRE, for managed ACA and IRIS filing

1099FIRE combines software with hands-on filing services. A TPA can send an Excel file, have U.S.-based staff prepare XML and PDF outputs, review the forms, and authorize transmission through IRS A2A channels. The company supports 1097, 1098, 1099, W-2G, and other IRIS information returns, along with ACA 1094/1095 software and outsourced ACA filing. Its ACA service can prepare originals or corrections, print and mail recipient copies, and assign an expert to the engagement. This model can help a TPA that prefers staff review over a fully self-serve workflow.

Human review and live support lift 1099FIRE above platforms with broader software automation but less direct help. The trade-off is reduced pricing and workflow transparency. Current outsourcing rates are quote-based. Direct state coverage, distinct user permissions, client-level dashboards, and W-2 filing are not publicly listed for the current service. Its fifth-place score reflects excellent support and validation balanced against those gaps. TPAs considering 1099FIRE should provide a representative file, ask for a written scope covering state and recipient services, and confirm how separate clients and correction rounds are priced.

• Location: Phoenix, Arizona
• Price Range: As of 09/2026, IRIS and ACA outsourcing is quoted per engagement or file
• Services Offered: IRIS information returns, ACA software, ACA outsourcing, Excel intake, validation, corrections, recipient copies, and live support
• Year Founded: More than 20 years in operation; exact year not listed on the current service page
• Review Score: 5.0/5 from 40+ Google reviews shown on the company site as of 09/2026

eFileMyForms, for transparent pay-per-form pricing

eFileMyForms publishes clear volume tables for W-2, 1099, 1098, 5498, ACA, and 1042-S filing. The service has no monthly subscription, and prices separate e-file-only orders from e-file, print, and mail packages. Direct state reporting and TIN matching have stated add-on prices. This approach helps a TPA estimate costs across client volumes without committing to an annual subscription. The platform also supports Excel or CSV uploads, mapped templates, corrections, multi-client filing, and ACA delivery options.

The strongest use case is variable-volume work where transparent per-form pricing matters more than advanced team administration. ACA coverage and a broad information-return library keep eFileMyForms relevant for benefits administrators, although public details on permissions, approval routing, and consolidated client reporting are limited. Recent independent reviews create a material concern: several reviewers report delayed transmission statuses and difficulty reaching support during the 2026 filing season. That evidence lowers the platform's support score despite its useful form and pricing coverage. TPAs should test support responsiveness, confirm expected transmission timelines in writing, and run a limited client batch before moving a full seasonal workload.

• Location: Not publicly listed
• Price Range: As of 09/2026, 1099/W-2 e-file starts at $2.99 per form for 1 to 20 forms and falls to $1.19 above 1,000; add-ons apply
• Services Offered: W-2, 1099, 1095/ACA, 1098, 5498, 1042-S, uploads, state filing, TIN matching, corrections, and recipient delivery
• Year Founded: Not publicly listed
• Review Score: 1.0/5 from 7 Trustpilot reviews as of 09/2026

WageFiling, for small straightforward batches

WageFiling offers browser-based entry for W-2, W-2C, 1099-NEC, 1099-MISC, 1099-DIV, 1099-INT, and 1098 Mortgage forms at a published flat rate of $3.49 per form. The platform submits forms to the IRS or Social Security Administration and supplies recipient PDFs for the filer to email or mail. It also publishes bilingual chat support, SSN masking, filing confirmation, and a try-before-you-buy option. That short path can suit a TPA with a small number of uncomplicated client filings.

The same simplicity limits its fit for larger TPA operations. Public pages do not establish multi-user permissions, client-level approval flows, bulk imports, TIN matching, 1095/ACA coverage, or full direct-state reporting. Recipient fulfillment also remains with the filer, creating another handoff during a deadline-driven period. WageFiling's pricing score is strong because the rate is simple and public, but the heavier criteria in this comparison concern multi-client administration, imports, complete delivery, and form breadth. A TPA should confirm account separation, correction handling, state obligations, and exportable filing records before relying on it across multiple clients.

• Location: Grand Rapids, Michigan
• Price Range: As of 09/2026, $3.49 per form with no subscription
• Services Offered: W-2, W-2C, selected 1099 forms, 1098 Mortgage, IRS and SSA e-file, recipient PDFs, SSN masking, and chat support
• Year Founded: Not publicly listed; the company says its proprietary software has been an IRS Trusted Supplier since 1996
• Review Score: No verified public third-party aggregate score found during the September 2026 research period
