Tax1099 Review (2026): 1099 & W-2 E-Filing for Accountants

Tax1099.com is a dedicated information-return e-filing service from Zenwork, and for accounting firms and bookkeepers that file 1099s and W-2s for clients every January it is one of the most established options. This review covers what it does well, where it costs extra, and who should use it. Our assessment is based on vendor documentation and published feature and pricing pages — not hands-on testing — and was last checked in October 2026.

Who it's for#

Accounting firms, bookkeepers, and small businesses that file more than a handful of information returns per year and want to e-file federal (and where needed state) copies, collect W-9s, and deliver recipient copies electronically instead of printing and mailing everything. If you file a few 1099-NECs for one business, your payroll or accounting software may already cover it; Tax1099 earns its keep at firm scale, where one dashboard handles many businesses and thousands of forms.

What it covers#

The form library is broad for a specialist tool: 1099-NEC, MISC, DIV, INT, R, B, K, and more, plus W-2 and W-2c, ACA 1095-B/1095-C, and 1042-S for withholding. Combined federal/state filing is supported for participating states, which removes a separate state-filing workflow for most common forms.

Data entry is where firm tooling matters most. Tax1099 imports from QuickBooks Online and Xero, accepts CSV uploads for bulk data, and offers an API for firms that want to automate from practice-management or bookkeeping pipelines. Recipient data can be collected through W-9 requests with e-signature, so contractor onboarding feeds straight into filing season.

TIN matching is built in: the service checks payee TINs against IRS records before you file, which catches the mismatch errors that otherwise generate B-notices after filing.

Delivery and recipient copies#

Recipient copies can be delivered by email (e-delivery with consent tracking) or postal mail as an add-on, or both. Email delivery plus IRS e-file means most firms touch paper only for recipients who require it.

Pricing#

Per-form pricing with volume discounts, charged per filing year, with e-delivery and postal mailing as paid add-ons. Rates change between seasons, so treat the vendor pricing page as the source of truth for the current season rather than any figure quoted in a review — including this one.

How it compares#

• Vs. your payroll software: payroll platforms file W-2s and sometimes 1099-NEC for workers paid through them, but contractor/NEC filing outside payroll and multi-client bulk filing is where a specialist wins.
• Vs. generalist e-file services (FileYourForms, eFile4Biz, Yearli): Tax1099's firm-oriented features — multi-business dashboards, QBO/Xero import, TIN matching, API — are the differentiators; pricing per form is competitive but not always the cheapest at low volume.
• For bulk filing at firms: see our 1099 e-filing services comparison and bulk 1099 e-filing for accounting firms.

Verdict#

For accounting firms and bookkeepers that file information returns for many clients, Tax1099 is the tool we recommend considering first: broad form coverage, TIN matching, real QuickBooks/Xero import, and recipient e-delivery in one dashboard. Budget for the add-ons, and price your season against alternatives before committing. Pair it with printed 1099 and W-2 form kits for the paper recipients you keep.
