Overview

Tax1099 is an IRS-authorized platform for filing informational returns and managing related compliance data. It suits businesses and tax professionals with varied forms or accounting-system integrations. Its broad filing coverage is useful, but the free plan allows no form filings.

Key features

Tax1099 supports 1099, W-2, payroll, ACA, 1098, 1042, tax-exempt, and other forms, with e-filing to the IRS, SSA, and states participating in the Combined Federal State Filing program. Corrected and void forms, scheduled filings, rejected-form resubmission, recipient copy downloads, and reports extend its usefulness beyond initial submission. That breadth fits organizations handling multiple reporting needs; someone filing only a few forms may prefer pay-per-form pricing to an annual team plan.

QuickBooks Online, Xero, and BILL have two-way 1099 data sync, while QuickBooks Desktop has import options. Other integrations or import routes include Zoho, Excel, FreshBooks, Sage Intacct, Tipalti, Entrata, Oracle NetSuite, and Zapier. API integration is also offered for tax software and applications, giving developers a route to connect their own products.

Security measures include annual SSAE-21 Type II audits, encryption, 256-bit security standards, TIN masking, and authentication procedures. Two-factor authentication uses a PIN or password sent to the registered phone. Secure four-year storage is included in the filing price. Live chat runs Monday through Friday, 8:30 AM to 6:00 PM Central Time, with 24/7 support during tax season.

Pricing

Tax1099 uses a freemium model, but Essential’s $0.00 per free plan is pay per form filed and permits zero free-plan forms. It is a starting point for individuals and small businesses, not a no-cost filing option. Form eFiling costs $2.99 USD per once for the first 20 forms, then $2.30 each for forms 21–150, $1.31 each for 151–500, and $0.68 each for 501–1,000; contact the company for pricing at 1,000+ forms. The per-form price falls with volume, though filing remains a cost to budget for each batch.

Teams costs $249.00 USD per year, billed $249/year, and adds features to Essential for SMBs and collaborative finance teams. Scale costs $349.00 USD per year, billed $349/year, and adds features to Teams for high-volume and growing organizations. These annual plans may suit teams that need their added capabilities, but the plan descriptions do not spell out their feature differences. TIN matching is separately priced at $1.00 per unit for real-time matching or $0.37 per unit within 24 hours; IRS-compliant eDelivery costs $0.25 per unit.

Both forms are covered, with federal and state e-filing, recipient delivery, and correction filing. The filing price includes four-year storage. These terms make the service more complete than a filing-only workflow, while optional matching and delivery add charges.

Platforms

Tax1099 is available on the web and through an API. Web access suits teams filing directly, while API access is aimed at software and application integrations.

Who it's for

The service is aimed at small and medium businesses, accountants, CPAs, bookkeepers, and corporations. Its range of forms and accounting connections can serve teams with recurring or varied reporting; the company also presents solutions for gig businesses, marketplaces, and crypto exchanges. Occasional filers should weigh the per-form fees and separately priced services against their limited filing needs.

Pros and cons

Pros

Broad form and filing coverage spans IRS, SSA, and participating state submissions, plus corrections and rejected-form resubmission.
Two-way sync with QuickBooks Online, Xero, and BILL, along with other import routes and an API, gives businesses several ways to connect filing data.
Four-year storage is included in the filing price, and two-factor authentication is offered.

Cons

The free plan includes zero forms, so even small filers pay to submit returns.
TIN matching and eDelivery are additional per-unit costs, which can raise the total beyond filing fees.
Annual Teams and Scale plans cost $249.00 USD and $349.00 USD respectively; their published summaries do not explain precisely what capabilities each adds.

Alternatives

For a free option that supports up to 100 returns at a time through manual entry or CSV upload, consider the IRS IRIS Taxpayer Portal; it requires an IRIS TCC. efile4Biz offers a free plan with pay-per-form filing, one user, reports, chat and email support, and $1 per TIN match. TaxBandits is another alternative. Yearli offers a free-to-start Core plan with W-2 and 1099 forms, quarterly filing, chat and email, and per-form TIN matching, alongside an annual subscription and filing fees. For ACA-focused filing, BoomTax offers a Premium (ACA) plan at $349.00 USD per once for Tax Year 2025, with up to 145 employees and unlimited companies. ExpressEfile, 1099 / 945 Forms, and eFileMyForms are also alternatives.

Verdict

Tax1099 is a strong fit for businesses and tax professionals that need broad informational-return coverage, accounting integrations, or API access. Its range of forms and filing workflows is the main reason to choose it; the zero-form free plan and extra charges for matching and eDelivery are the main reasons to compare alternatives, especially for low-volume filers.
