Best Contractor Payroll Services in 2026

§1Software vs. managed services: what is the difference

Gusto

Justworks

Paychex

Wave Payroll

OnPay

Contractor payroll searches split between two intents. "Software" intent: a tool you use yourself to run contractor payments, automate 1099s, and manage compliance. "Services" intent: a third party that handles the payroll process for you, you provide the hours and contractor information, they do the processing, tax filing, and distribution.

Most growing companies start with self-service software (lower cost, more control) and graduate to managed services as headcount grows and the administration burden increases. The crossover point is typically 20-30+ contractors, or the point where a part-time payroll administrator's time exceeds the cost of managed services.

§2Self-service contractor payroll software

Gusto Contractor Plan ($35/month base plus $6/contractor) is available only to companies already on it. Since October 1, 2026, new customers cannot select it and existing customers cannot switch into it. It handles ACH payments, W-9 collection, digital 1099-NEC filing, and a contractor portal. Five paid contractors cost $65/month at the listed rate. Adding W-2 employees requires moving to another Gusto plan, and you cannot move back.

Deel ($49/contractor/month, global): For international contractors, Deel is the standard. Covers payment in 150+ countries, locally compliant contracts, 1099-NEC filing for US contractors, IP protection clauses, and contractor self-service for invoicing and payment method selection.

Wave Payroll ($40/month base + $6/employee or contractor): Handles both W-2 employees and contractors, with automatic tax filing included in all 50 states since Wave unified its pricing in April 2025. Best for very small businesses with a mix of employees and contractors who already use Wave for accounting.

§3Fully managed contractor payroll services

For companies that want payroll handled rather than self-managed, several options exist at different price points. Gusto Full Service Payroll: Gusto's full-service add-on (available on Plus and Premium plans) where Gusto's team reviews and runs payroll on your behalf rather than you running it. Pricing is higher than self-service but lower than dedicated payroll service firms.

Justworks is a PEO (Professional Employer Organization): it co-employs your workers and handles payroll, benefits, workers' comp, and compliance administration. Pricing runs about $79/employee/month on the Basic plan and $124/employee/month on Plus. It fits companies that want payroll and HR handled together by one outsourced provider.

Justworks doesn't publish pricing details that automated tools can fetch (their pricing page still blocks scrapers as of September 2026), so these numbers are cross-referenced from third-party pricing trackers rather than the vendor directly: $79/employee/month on Basic, $124/employee/month on Plus (raised from $109 for new business effective June 2026), with volume discounts pulling Plus down once a company passes roughly 25-50 employees. Confirm the current rate with Justworks sales before you commit. G2 reviewers rate Justworks highly for benefits access and ease of use, especially among small teams of 10-50 employees that want PEO co-employment without running their own HR stack.

Paychex PEO (Paychex Flex): Paychex offers both self-service software and full PEO services. PEO pricing is custom (typically $150-200/employee/month for the full PEO bundle including benefits). Best for companies that need enterprise-grade compliance support.

§4Misclassification risk: the compliance issue behind contractor payroll

Contractor payroll software handles the mechanics of payment and tax filing, but it does not protect you from worker misclassification liability. The IRS, Department of Labor, and many state agencies apply their own tests for independent contractor status. Misclassifying an employee as a contractor can result in back taxes, penalties, and unpaid benefits.

The core test: does the company control how the work is done (not just the result)? If yes, the worker is likely an employee. Payroll software cannot change the underlying work relationship, it only processes payments for whatever classification you have determined. This is why the IRS guidance and state labor department resources matter more than the payroll tool for the classification decision.

§5Frequently asked questions

Do I need payroll software if I only pay contractors? Yes, for one specific reason: 1099-NEC filing. Any contractor you pay $2,000 or more across the year (up from the old $600 line for 2026 payments onward, per the 2025 tax law change) must receive a 1099-NEC by January 31. Filing these manually via the IRS FIRE system is feasible for 1-2 contractors but becomes error-prone at 5+. Compare the filing features and total fees of plans you can actually join. Gusto's legacy $35-base subscription is closed to new signups and plan switches. Companies already enrolled may retain their subscription.

Can contractors pay themselves through payroll software? Self-employed contractors generally pay themselves through ACH transfer from their business account, not through an employer's payroll system. The payroll software is used by the company paying the contractor, to record payments and file 1099s. The contractor receives payment and manages their own quarterly estimated taxes.

§6Gusto and OnPay: best self-service for US contractors

For US contractor payments, compare Gusto and OnPay using plans available to your company. Gusto holds a 4.5/5 on G2 across thousands of reviews. Existing contractor-only customers pay a $35 monthly base plus $6 per contractor; new customers must choose another plan. Its full Simple plan starts at $49/month base plus $6 per person and supports W-2 employees and 1099 workers. Gusto files 1099-NECs automatically at year-end, runs unlimited payroll runs, and handles direct deposit. The plan-specific help page says legacy subscribers are charged only in months when they pay a contractor. That condition applies to the old subscription; other plans have their own base-fee terms. General guidance about waiving an unpaid contractor's per-person fee alone cannot establish the total bill.

OnPay Payroll Essentials charges $49/month base plus $6 per person for employees and contractors. OnPay also scores 4.8/5 on G2 and includes automated 1099 filing. Its current pricing page lists HR as an add-on at $15/month base plus $2 per worker. For five paid contractors, the base payroll cost is $79/month. Gusto's $65 contractor-only comparison applies to existing subscribers, not new buyers. Source: OnPay "Pricing", checked October 8, 2026.

For a new US contractor account, compare OnPay's $49 base plus $6/person with an available Gusto payroll plan. Existing Gusto contractor-only subscribers should compare their current terms before switching. Both handle multi-state contractor payments without add-on fees, generate year-end tax forms, and let contractors enter their own W-9 and bank details. A waiver of an unpaid contractor's per-person fee is not a general promise of a zero-dollar monthly bill.

§7Deel: best for international contractors

For international contractors, compare country coverage and fees before choosing a platform. Gusto supports international contractor payments; its legacy contractor-only plan requires at least one US contractor before using that feature. Deel is another option. Deel pays contractors in 150+ countries, supports 15+ payout methods (local bank transfer, PayPal, Wise, Payoneer, even crypto), and carries a 4.8/5 rating on G2. Its contractor product runs about $49 per contractor per month, which is higher per head than a US tool but reflects what it's actually doing: handling cross-border compliance, currency conversion, and locally compliant contracts in each jurisdiction.

Deel's core value is compliance coverage you can't easily build yourself. It generates locally vetted contractor agreements, screens for permanent establishment and misclassification risk in each country, and collects the right tax documents automatically (W-9 for US contractors, W-8BEN for foreign ones). At year-end it still files 1099-NECs for your US-based contractors, so a mixed domestic-and-international roster lives on one platform instead of two. That consolidation is the real reason finance teams choose it over stitching Gusto plus a stack of international wire transfers.

Deel makes sense once you have even one or two contractors abroad and the compliance exposure outweighs the per-head premium. If your entire roster is US-based, you're overpaying for capabilities you'll never touch. OnPay or Gusto will cost a third as much. A common pattern: run US contractors on OnPay at $6/head and route international contractors through Deel, keeping each platform on the work it's built for. Just confirm your accounting system can reconcile both feeds before you split the roster.

§81099-NEC automation and the $2,000 threshold

The compliance trigger every US business has to track is the $2,000 threshold: if you pay an independent contractor $2,000 or more in a calendar year, you must file a Form 1099-NEC reporting that compensation to the IRS and send a copy to the contractor by January 31. That figure is new for 2026: the One Big Beautiful Bill Act raised it from the $600 threshold that applied through the 2025 tax year, and the IRS will index it for inflation starting in 2027; payments made in 2025 are still governed by the old $600 rule. The form is specifically for non-employee compensation, and it replaced box 7 of the old 1099-MISC back in 2020. Miss the deadline and penalties scale with lateness, running from $60 to $340 per form depending on how late you file, and climbing to $680 or more per form if the IRS treats it as intentional disregard.

Manual 1099 prep is where small teams get burned. You need each contractor's W-9 on file (legal name, address, and TIN), an accurate running total of what you paid them, and clean reconciliation against your books. Platforms like Gusto, OnPay, and Deel automate the entire chain: they collect the W-9 at onboarding, tally payments as you run them, generate the 1099-NEC, e-file with the IRS, and distribute copies to contractors, usually at no extra charge on plans that already include contractor payments. That automation is the strongest argument for using payroll software over a spreadsheet once you cross even a handful of contractors.

Two details that trip people up. First, the $2,000 threshold is per payer, per year, so it doesn't reset if you switch platforms mid-year, and a contractor paid $1,200 through one tool and $900 through another still crosses the line and needs a 1099. Second, since the 2023 tax year, businesses filing 10 or more information returns must e-file, paper is no longer allowed at that volume. Any reputable payroll platform e-files by default, so this only becomes a problem if you're still mailing forms yourself. Keep W-9s current and let the software watch the threshold for you.

§9Cost comparison: per-contractor pricing

Per-contractor pricing splits into two models: a base fee plus per-head charge (Gusto, OnPay) that rewards larger US rosters, and a flat per-contractor rate (Deel) that carries no base fee but costs more per person. The table below shows real monthly pricing and what each tier includes, so you can match the platform to your roster size and where your contractors are located.

For five paid US contractors, the listed monthly fees are $65 on Gusto's existing-customer contractor-only plan and $79 on OnPay Payroll Essentials. New buyers cannot select the former. At $245/month for five contractors, Deel costs about 3.1 times the OnPay base payroll fee ($245 / $79), before any optional services or payment charges. The products have different coverage, so this arithmetic alone does not establish which fits your business.

One scenario that catches growing teams: a 10-person agency with 7 US contractors and 3 overseas. Running everyone through Deel costs about $490/month; splitting the roster (7 US contractors on OnPay at $91/month and 3 international on Deel at ~$147/month) lands near $238/month for the same coverage. The split adds one reconciliation step in your accounting but cuts the bill by more than half. Always price against your actual contractor mix and location, not the headline base fee.
