Running payroll in Connecticut is not like running payroll in Texas or Florida. Between State Disability Insurance (SUI), Paid Family Leave (PFL), daily overtime rules, constantly changing local minimum wages, and strict CT UI reporting requirements, Connecticut payroll is among the most complex in the nation. Choosing the right payroll software is not just a convenience — it is a compliance necessity.

We spent weeks evaluating the leading payroll platforms specifically through the lens of a Connecticut small business owner. This guide covers pricing, features, Connecticut-specific compliance, ease of use, and our honest recommendation for 2026.

Why Connecticut Payroll Is Uniquely Complex

Connecticut requires employers to handle: SUI withholding (1.2% in 2026 on wages up to $153,164), PFL contributions, daily overtime calculations (not just weekly like federal law), local minimum wage tracking for 40+ cities, and quarterly CT UI filings (DE 9 and DE 9C). Basic payroll software that works fine in other states can leave you exposed to penalties in Connecticut.

Why Connecticut Businesses Need Specialized Payroll Software

If you operate in any other state, you might get away with bare-bones payroll processing. Connecticut is different. Here is what makes Connecticut payroll uniquely demanding:

Bottom line: you need payroll software built with Connecticut in mind, not a generic national platform with Connecticut bolted on as an afterthought.

1. Gusto — Best Overall for Connecticut Small Businesses

Quick Verdict: Gusto is our top pick for Connecticut small businesses with 1–50 employees. It handles CT-specific taxes automatically, has an intuitive interface, and offers the best price-to-value ratio on the market.

Pricing: Gusto's Simple plan starts at $40/month base + $6/month per employee. For a business with 5 employees, that is $70/month. The Plus plan runs $80/month base + $12/employee and adds advanced features like time tracking, PTO management, and next-day direct deposit.

What Makes Gusto Stand Out for Connecticut

Gusto Pros and Cons

Pros: Transparent pricing, excellent CT tax automation, beautiful user interface, strong customer support, integrated HR tools, free contractor payments on Simple plan.

Cons: Phone support limited to Plus plan and above, no dedicated payroll representative (unlike Paychex), limited international payroll capabilities.

Special Offer

Gusto offers a free trial so you can test the platform before committing. For most Connecticut small businesses, Gusto pays for itself in time saved and penalties avoided.

2. Paychex — Best for Growing Teams (10+ Employees)

Pricing: Paychex uses custom pricing based on your business size and needs. Expect to pay roughly $60–$150+/month depending on the plan and number of employees. You will need to request a quote.

Paychex is a well-established payroll provider that has been in business since 1971. It is a strong option for Connecticut businesses that are outgrowing basic payroll software and need more hands-on support.

Paychex Strengths

Paychex Pros and Cons

Pros: Dedicated support rep, comprehensive HR tools, excellent scalability, strong compliance track record, pay-as-you-go workers' comp.

Cons: Opaque pricing (must call for a quote), interface less modern than Gusto, can be expensive for very small businesses, long-term contracts may apply.

3. QuickBooks Payroll — Best for Existing QuickBooks Users

Pricing: QuickBooks Payroll starts at $50/month base + $6/month per employee for the Core plan. The Premium plan (with same-day direct deposit and HR tools) runs $80/month + $8/employee. Elite is $130/month + $11/employee.

If your business already runs on QuickBooks for accounting, QuickBooks Payroll is a natural extension. The integration between the two products is seamless — payroll expenses automatically flow into your books with zero manual entry.

QuickBooks Payroll Strengths

QuickBooks Payroll Pros and Cons

Pros: Best-in-class accounting integration, familiar interface for QuickBooks users, auto payroll feature, tax penalty protection on Elite plan.

Cons: More expensive than Gusto at the base level ($50 vs $40), CT daily overtime tracking requires manual setup on Core plan, customer support can be inconsistent, limited HR tools compared to Gusto or Paychex.

Important Note: If you do not already use QuickBooks for accounting, there is little reason to choose QuickBooks Payroll over Gusto. The main advantage of QB Payroll is its integration with the QuickBooks ecosystem. As a standalone payroll solution, Gusto offers more features at a lower price.

4. ADP — Best for Large Enterprises (Not Recommended for Most Small Businesses)

Pricing: ADP uses custom pricing only. ADP Run (their small business product) starts around $79/month + $4–$10/employee, but final pricing depends on your quote. Enterprise plans (Workforce Now) can run into thousands per month.

ADP is the largest payroll company in the world, processing payroll for roughly 1 in 6 U.S. workers. However, being the biggest does not mean being the best fit for every business.

ADP Strengths

ADP Pros and Cons

Pros: Unmatched scalability, deep compliance expertise, PEO option, extensive integration marketplace.

Cons: Overkill for businesses with fewer than 25 employees, opaque and often expensive pricing, long-term contracts, clunky user interface compared to modern competitors, customer service quality varies widely by region and rep.

Our Honest Take on ADP for Small Business

Unless you have 50+ employees or need multi-country payroll, ADP is likely more complex and expensive than you need. For most Connecticut small businesses, Gusto or Paychex will deliver better value with less friction.

What to Look for in Connecticut Payroll Software

When evaluating any payroll platform for your Connecticut business, make sure it checks these boxes:

Must-Have Features

  1. Automatic Connecticut tax calculations: SUI, PFL (funded through SUI), SUI, ETT, and PIT must be calculated automatically with current rates. For 2026, the SUI rate is 1.2% on wages up to $153,164, the SUI rate for new employers is 3.4%, and the ETT rate is 0.1% on the first $7,000 per employee.
  2. CT UI filing: The software should file your DE 9, DE 9C, and DE 88 forms electronically with the EDD.
  3. Daily overtime tracking: This is non-negotiable for Connecticut. Any software that only tracks weekly overtime will miscalculate pay for your hourly employees.
  4. Compliant pay stubs: Connecticut Labor Code Section 226 has nine required elements on every pay stub. Your software should generate compliant stubs automatically.
  5. New hire reporting: Connecticut requires new hire reporting within 20 days to the EDD.
