Best Payroll Tools 2026

Frequently Asked Questions

What is the best payroll software for small businesses?▾

Gusto is the most popular modern payroll platform for US small businesses - automated federal/state tax filing, employee self-service portal, benefits integration, and contractor payments. ADP and Paychex serve mid-market and enterprise. QuickBooks Payroll integrates seamlessly for QuickBooks accounting users. Rippling combines payroll with HR and IT management for rapidly scaling teams.

What taxes does payroll software handle?▾

Payroll software calculates and deposits: federal income tax withholding, Social Security tax (6.2% employee + 6.2% employer), Medicare tax (1.45% + 0.9% additional for high earners), state income tax, state unemployment tax (SUTA), and federal unemployment tax (FUTA). Full-service payroll (Gusto, ADP) files quarterly 941s and annual W-2s and W-3s automatically. This compliance automation is the primary value of payroll software.

Can I use payroll software for contractors (1099 workers)?▾

Yes - most modern payroll platforms (Gusto, Rippling, Deel) handle contractor payments alongside W-2 employees. Contractor payments have simpler tax requirements (no withholding or employer tax matching) but require accurate 1099-NEC filing at year end for US contractors paid over $600. Deel specializes in global contractor and international employee payments with local compliance handling.

Why is payroll usually automated rather than done manually?▾

Because payroll is complex, deadline-driven, and unforgiving of errors. It involves calculating gross-to-net pay, withholding the correct income and payroll taxes, applying benefit deductions, filing with tax authorities on time, and generating year-end forms, all governed by rules that change and vary by location. Manual payroll is slow and prone to mistakes that trigger penalties or unhappy employees. Payroll software automates the calculations and filings, keeps up with changing tax rates, and dramatically reduces the risk of costly compliance errors.

Can payroll software handle both employees and contractors?▾

Most modern payroll tools handle both, though they are treated differently. Employees have taxes withheld, receive benefits, and generate forms like the W-2, while contractors are typically paid gross with no withholding and receive a 1099 or local equivalent. Good payroll software distinguishes the two, applies the correct tax treatment, and generates the right year-end documents for each. Many tools also support international contractors and employees, adapting to different countries' rules, which is valuable for teams that hire across borders.

What payroll taxes does the software handle automatically?▾

Payroll software typically calculates and withholds employee income tax, and the various payroll taxes such as Social Security and Medicare in the U.S. or their equivalents elsewhere, then remits both the employee and employer portions to the tax authorities. It also handles filings and generates year-end forms. The software keeps current with changing tax rates and thresholds, which is one of its main values, since these rules change regularly and vary by jurisdiction. This automation removes the largest source of payroll errors and penalties.
