Best 1099 Filing Software for Bookkeepers: 6 Tools, 2027

Key Takeaways

• Choose the billing unit before the brand. Per-form tools, per-client suite licenses and flat subscriptions produce very different totals for the same filing season.

• Tax1099 and Avalara's Track1099 both publish per-form pay-as-you-go schedules. Tax1099 also sells multi-user plans, while Avalara quotes its annual subscription.

• TaxBandits publishes federal tiers and a developer API, which suits firms that want to script the filing steps.

• Accounting CS bills per client and form type, so it fits firms already running that suite. QuickBooks Online includes 1099 e-filing in its contractor plan, but that pricing page needs a careful read.

• The IRS's IRIS portal is free, but it is a batch portal, and software filing requires its own credentials.

• Plan 2027 filings around IRIS as the intake system, and count payees against the higher threshold before you buy.

The category decision comes before the brand

A 1099 filing tool collects each payee's name and taxpayer identification number (TIN), checks those details, prepares Form 1099-NEC or 1099-MISC, and sends the returns to the IRS and to recipients.

TL;DR: Pick the billing unit that matches how your firm invoices clients, confirm the route into IRIS, and shortlist the one or two tools whose published prices fit your form count.

Bookkeeping firms usually choose among three channels. A standalone e-file service bills per form, so you pay for what you file. A ledger add-on, such as the contractor plan in QuickBooks Online, keeps payee data where the bookkeeping already lives. A tax-firm suite, such as Accounting CS, bills per client and form type, which suits firms that already run that software. The IRS's own portal sits underneath all three as a free option for small batches.

Our recommendation follows from that split. If client books already live in QuickBooks Online, test its e-file option before paying for a second service. If you file for many clients from one office, compare a per-form service against a suite license using your real client count, because per-client and per-form billing reward opposite habits. If your firm also prepares returns in a desktop suite, check that suite's 1099 module first.

How we evaluated these tools

This guide is built from vendor pricing pages, IRS material and independent trade sources. It does not report hands-on filing results. The weights below are our judgment about what a bookkeeping firm needs, not scores published by any vendor.

Factual vendor data appears in the pricing and profile sections with inline citations. Our judgment appears in the weights, the fit table and the checklist. We considered Gusto, eFileMyForms, 1099-Etc and 1099FIRE, but their official pricing pages did not open during this review, so they are not priced below.

Published pricing, checked for this guide

Pricing checked October 25, 2026.

Teams plan on Tax1099: $249 per year according to Tax1099 (2026), with the Scale plan at $349 a year adding API access and the Essential plan carrying no annual fee. Tax1099's per-form chart starts at $2.99 for the first 20 forms and falls to $0.72 for forms 501 to 1,000, according to Tax1099 (2026). The page does not label which form types each chart covers, so confirm the chart with the vendor before you budget.

Pay-as-you-go IRS e-file, forms 1–15: $3.10 each according to Avalara (2026), with forms 16 to 165 at $2.30, forms 166 to 500 at $1.30 and forms 501 and up at $0.63, plus $1.49 per form for state filing and $0.45 per form for TIN matching, all priced by cumulative volume. The annual subscription has no published dollar amounts and is Quote-based, and refunds end once an IRS, state or recipient filing or delivery is sent.

The Contractor Payments plan on QuickBooks Online shows $25 with a "Save 50% for 3 months" offer that brings the monthly figure to $12.50, and it includes 20 contractors with $2 for each additional one, according to Intuit (2026), which also dates Form 1099-NEC to February 1, 2027. The page does not say what the $25 figure represents, and it mentions no print-and-mail fees.

On Accounting CS, the federal 1099 e-file charge is $16 per client per form type when sent through CS Connect, according to Thomson Reuters (2026). The unlimited 1099 e-filing license is Quote-based, and the help page does not say whether it replaces the per-form charge.

TaxBandits publishes federal tiers for 1099 e-file and sends filers above its top published tier to contact sales, so the worked example below runs its tiers through a real-sized season.

The table turns those cited figures into two season sizes. It is arithmetic on the tiers above, not a quote.

Thomson Reuters bills by client, so its row counts clients rather than forms. The Teams row adds the annual plan price cited above to the per-form charges in the first row.

What the 2026 threshold change does to your form count

Reporting threshold: $2,000 per payee per year according to Anchin (2026), effective for payments made on or after January 1, 2026. Payees whose totals stay below that line may drop off your filing list, but payments are added up per payee for the calendar year, so several smaller payments to one contractor still count together. The threshold is indexed for inflation in later years, so do not hard-code it into a template.

IRIS, FIRE and the 2027 filing path

The IRS's IRIS page describes its web portal as free, limits each batch to 100 returns and requires a five-digit transmitter control code (TCC), according to IRS (2026), and filers with 10 or more information returns must file them electronically. Software that files through the application-to-application route needs its own TCC and an API Client ID, and it must pass IRS testing before it transmits production returns.

A March 2026 trade article reports that the IRS plans to retire FIRE on December 31, 2026, with IRIS as the sole required intake system from the 2027 filing season, according to FinTech Global (2026). That article attributes its warning to a RegTech firm and does not tie the date to an IRS publication, and the IRS filing page reviewed for this guide does not mention FIRE, so confirm the date on IRS.gov before you plan around it.

A 125-form season at published rates

Illustrative scenario, not a customer: a bookkeeping firm files 125 forms for clients in one season and TIN-matches all 125 payees. At TaxBandits' published federal tiers, the first 10 forms cost $2.75 each, forms 11 to 100 cost $1.75 each and forms 101 to 125 cost $1.15 each, so e-file fees come to $213.75 ($27.50 + $157.50 + $28.75), TIN matching at $0.35 per TIN adds $43.75, and mailing every recipient copy at $1.85 per form adds $231.25, for $488.75 in all, according to TaxBandits (2026). The developer documentation lists three DistributionType values, including POSTAL_ONLY, which is the setting to check before paying to mail copies, according to TaxBandits (2026).

Feature matrix for bookkeeping workflows

Vendor profiles: best fit, limits and evidence

Tax1099 (Tax1099.com)

Best fit: firms that want team logins and an API option, once the per-form chart for their form types is confirmed.

Limitations: the per-form charts do not name their form types, volumes above the top published tier are Quote-based, and Scale's single sign-on carries a one-time implementation fee on contact.

Implementation: start on the pay-as-you-go plan with one payer group, move to Teams for shared access, and reserve Scale for API work. Real-time TIN matching is billed per request, while bulk matching includes a free first batch for Teams and Scale customers.

Primary evidence: Tax1099 pricing page.

Avalara (Track1099)

Best fit: firms that want W-9 collection, TIN matching, state filing and recipient e-delivery in one account. The Avalara pricing page lists those items as included in its annual subscription.

Limitations: annual plan prices are not published, so get a written quote. Postal mail is priced per mailing and costs more for late-January mailings, and the plan table shows TIN matching only at its largest tier.

Implementation: the page is titled "Avalara (Track1099)" and links to Track1099 sign-in, so confirm which account and login your staff will use before onboarding.

Primary evidence: Avalara 1099 pricing page.

TaxBandits

Best fit: firms that want per-form pricing with documented API steps for creating, approving and transmitting returns, plus separate recipient-distribution options.

Limitations: the pricing page uses two different large-volume thresholds in different places, and its calculator shows placeholder values rather than an estimate.

Implementation: map your payee fields to the create step and build a human approval point before transmission. Ask whether recipient copies go by post, online access or both, because the API treats those as distinct distribution types.

Primary evidence: TaxBandits pricing page and TaxBandits developer documentation.

QuickBooks Online (Contractor Payments)

Best fit: firms whose client books already live in QuickBooks Online and that pay contractors through it.

Limitations: the first price on the page is not explained, the included contractor count drives extra fees, and the page does not describe print-and-mail charges. Payroll-first setups are a different plan on the same page.

Implementation: confirm each contractor's 1099 flag and TIN before the season, because the filing reads from the vendor profile. The page says unlimited 1099 e-filing is included.

Primary evidence: Intuit 1099 e-file page.

Thomson Reuters Accounting CS

Best fit: firms already on Accounting CS that file for many clients from one system and want client-based billing.

Limitations: cost follows the client count rather than the form count, the unlimited license is Quote-based, and the help page names the product but no subscription tier.

Implementation: confirm the CS Connect route and the IRIS path with your Thomson Reuters representative before you migrate client files.

Primary evidence: Thomson Reuters help page on 1099 e-filing.

IRS IRIS portal (free baseline)

Best fit: a firm with a short, stable list of forms and one person who files them each year.

Limitations: the portal takes manual entry or CSV upload only, and the IRS page reviewed for this guide does not describe TIN matching or state filing. Software filing is engineering work, not a configuration.

Implementation: a firm building its own A2A connection needs a TCC, an API Client ID and IRS testing before production.

Primary evidence: IRS IRIS e-file page.

When NOT to use US Tech Automations: skip it if your firm files a few forms once a year, because the IRS portal or a vendor's pay-as-you-go plan is simpler than building any workflow. Skip it if your ledger already produces a complete 1099 report and you only need an e-file step with a clean import, since the ledger's own filing or a suite license may be enough. Skip it if you want the filer to hold TIN records and run W-9 collection end to end, because a per-form vendor with W-9 tools covers that without a custom build.

Which tool fits which firm

Where a proposed workflow fits the year-end run

A configurable design from US Tech Automations would sit between your ledger and your filer. It is a proposed design, not a description of a live deployment. The trigger is a payee's year-to-date payments in the ledger reaching the threshold for the calendar year, or a new vendor being created without a W-9 on file. The workflow then pulls the vendor list and payment totals through the ledger's API or a CSV export, groups payments by payee, and compares each TIN against the W-9 record. Its output is a draft list of 1099-NEC candidates and a flagged queue of payees with missing or mismatched TINs. Prerequisites are ledger API or export access, a filer with documented create and approve endpoints, and a named reviewer. The human review points are a bookkeeper confirming each payee's form type and TIN before anything is submitted, and a second person approving the batch.

The transmission step follows the approval. The trigger is a reviewer marking a batch as approved in the review queue. The workflow then calls the filer's approval and transmit steps, which the TaxBandits documentation lists as separate operations. The output is a filing log with the SubmissionId the filer returns, each batch's status, and any rejected records routed back to a person. Prerequisites are filer API credentials and a test batch that passes validation. Human review points are the approval itself and every rejected record, which should go back to a person rather than resubmit automatically.

Building it yourself versus configuring it

The real alternative for many firms is stitching this together in Zapier, Make or n8n, or writing a script. Those tools can keep run histories, retry failed steps and route errors to a separate branch when someone configures them, and they can carry audit evidence if the workflow is designed to write it. The buyer still owns the hard parts: idempotency so a rerun does not double-file, escalation paths, access controls on TIN data, and maintenance when the ledger or filer changes its API. A proposed US Tech Automations design could configure duplicate-run checks keyed to the filer's submission identifier, a reviewer queue before transmission, and a log of who approved each batch. It would still need the prerequisites above, and the firm would still own its TIN data, its approval policy and its choice of filer.

Who this is for

This guide is for an owner or operations lead at a small accounting business who files 1099s for clients and is choosing a tool before the next season.

Red flags: you need one flat price for unlimited filing with no quote; your payee data cannot be exported or imported without retyping; or you file a short, one-time list that the free IRS portal already covers.

A decision checklist before you pay

• Count last year's payees under the 2026 threshold, recipient by recipient.
• Choose the billing unit: per form, per client and form type, or monthly plan.
• Confirm how the filer reaches IRIS, either under its own TCC or through the vendor's A2A route.
• Ask how TIN matching is priced and what happens on a mismatch.
• Decide between e-delivery and postal copies, and check each recipient-copy price.
• Get any 1,000-plus, annual or unlimited quote in writing before the season.
• Test one client file end to end before the filing window opens.
• Confirm refund and correction terms in writing.

Terms you will see on vendor pages

• TIN matching: a check of a payee's name and TIN against IRS records before filing. Vendors price it per request, per TIN or per batch.

• TCC (Transmitter Control Code): a five-digit IRS code that identifies the transmitter. The IRIS portal requires one.

• IRIS: the IRS Information Returns Intake System, the free portal and the application-to-application channel for software.

• A2A: application-to-application submission, where software sends returns to IRIS directly after IRS testing.

• FIRE: the older IRS filing system that a trade article reports will retire at the end of 2026.

• Recipient e-delivery: sending the payee copy electronically rather than by post, which usually avoids printing and postage charges.

Questions buyers ask first

Do I need paid 1099 software if the IRS portal is free?

Not always. The IRS portal is free, but it is a batch portal rather than a bookkeeping workflow, so it fits a short, stable list of forms better than a growing client book.

Does the higher threshold mean I can skip most 1099s?

It can reduce the forms you file, but only for payees whose calendar-year totals stay below the line. Add up payments per payee before you assume anyone drops off.

Which billing model is cheapest for a bookkeeping firm?

The cheapest model depends on client count and form count. Per-form tools win at low volume, while per-client suite pricing can win when each client has many forms.

Do I need my own TCC if I file through a vendor?

Ask the vendor which TCC it files under. The IRS portal requires a TCC, and software filing through the A2A route also requires one, along with an API Client ID.

Can I file 1099s from QuickBooks Online or Xero directly?

Check whether the ledger's e-file step is included in your plan or sold as a separate product before you rely on it. The filing step is often the part that costs extra.

Should I plan around FIRE in 2027?

Plan for IRIS. Treat any FIRE-era instructions in older vendor documentation as out of date.

Where to go from here

For most bookkeeping firms, the decision comes down to three questions: how you bill clients, whether your ledger already holds clean payee data, and whether the filer can reach IRIS under credentials you control. Answer those, shortlist one per-form tool and one ledger or suite option, and get written quotes for any tier you cannot price from a public page.
