Connecticut's sales tax system offers businesses the advantage of simplicity with a single statewide rate of 6.35% and no additional local taxes to navigate. Understanding Connecticut sales tax is crucial for businesses operating in the Constitution State, whether you're based in Hartford's financial district or serving customers from coastal communities.
This streamlined approach makes Connecticut sales tax compliance more straightforward than many other states, though the state maintains specific requirements and exemptions that businesses must understand to ensure proper compliance and take advantage of available benefits.
The Connecticut sales tax rate stands at 6.35% statewide, applying uniformly across all cities and towns throughout the state. Unlike many other states that allow local jurisdictions to add their own sales taxes, Connecticut maintains a single rate that simplifies compliance for businesses operating in multiple locations.
This consistent rate structure provides significant advantages for businesses. You don't need to track different rates for different locations within Connecticut, making point-of-sale systems simpler to configure and reducing the complexity of tax calculations for multi-location businesses.
The 6.35% rate applies to most retail sales of tangible personal property and many taxable services. However, Connecticut does maintain special rates for certain categories of items that reflect policy goals around luxury consumption and essential services.
While the standard Connecticut sales tax rate is 6.35%, certain items face different rates that businesses need to understand. These variations address specific policy objectives while maintaining the overall simplicity of the system.
Luxury items face higher rates to generate additional revenue from high-end purchases. Motor vehicles with sales prices exceeding $50,000 are taxed at 7.75%, as are items of jewelry exceeding $5,000 in value, and clothing or accessories priced above $1,000.
Meals and certain beverages at restaurants are taxed at 7.35%, slightly higher than the standard rate. This applies to prepared foods consumed on premises as well as takeout orders from restaurants and similar establishments.
Computer and data processing services, along with certain software, face a reduced rate of 1% when sold for business use, though personal use remains at the standard 6.35% rate. This differential encourages business technology adoption while maintaining revenue from consumer purchases.
Connecticut's nexus rules determine when businesses must collect and remit Connecticut sales tax. The state applies both traditional physical nexus concepts and modern economic nexus standards that reflect contemporary business practices.
Physical nexus in Connecticut is established through traditional indicators like maintaining offices, warehouses, retail locations, or having employees conducting business activities within the state. Even temporary presences like trade shows can create nexus obligations.
Connecticut implemented economic nexus rules requiring out-of-state businesses to collect sales tax based on their economic activity within the state. If your business has gross receipts exceeding $100,000 or 200 or more separate retail sales transactions in Connecticut during the previous or current calendar year, you've established economic nexus.
The dual threshold approach means businesses can trigger nexus requirements either through sales volume or transaction count. This is particularly relevant for businesses selling lower-priced items where the transaction count threshold might be reached before the revenue threshold.
Connecticut's economic nexus rules apply on a rolling twelve-month basis, requiring businesses to monitor their Connecticut sales regularly. Once you exceed either threshold, you must register and begin collecting Connecticut sales tax going forward.
Before collecting any Connecticut sales tax, businesses must obtain a Sales and Use Tax Permit from the Connecticut Department of Revenue Services (DRS). The registration process uses the state's myconneCT online system, which has modernized and streamlined compliance activities.
Registration requires a $100 fee, which is higher than many states but covers a two-year period. The permit automatically renews every two years at no additional cost, provided your account remains active and in good standing.
The online registration through myconneCT requires basic business information including your Federal Employer Identification Number (EIN) or Social Security Number for sole proprietors, legal business name, business address, and detailed information about your business activities.
You'll need to provide information about the types of products or services you'll be selling, projected sales volumes, and whether you'll be operating from multiple locations. Each location requires a separate permit, though they can all be managed through a single myconneCT account.
The system processes most applications immediately, providing a temporary permit you can print and use while the official permit is mailed to you. This immediate processing helps businesses begin operations without delays.
Connecticut sales tax applies to retail sales of tangible personal property and specifically enumerated taxable services. The state's approach focuses primarily on goods while taxing fewer services than many other jurisdictions.
Most physical items sold to consumers are subject to Connecticut sales tax, including clothing, electronics, furniture, vehicles, and household goods. Digital products delivered electronically are generally treated as tangible personal property and thus taxable.
Connecticut taxes fewer services than many states, but certain services are specifically subject to sales tax. These include admissions to entertainment events, certain repair services, telecommunications services, and specific business services like data processing.
Installation services often become taxable when they involve tangible personal property, while pure services that don't result in tangible goods typically remain exempt. The distinction can be nuanced, requiring careful analysis of specific business activities.
Transportation services like taxi rides and car rentals face sales tax, as do accommodations at hotels and similar lodging establishments. These services support Connecticut's tourism industry while generating revenue for state operations.
Connecticut provides numerous sales tax exemptions designed to reduce costs for essential items, support business operations, and encourage specific economic activities. Understanding these exemptions can provide substantial savings for qualifying purchases.
Connecticut exempts most unprepared food items from sales tax, recognizing food as an essential need. This exemption covers basic grocery items like bread, milk, meat, produce, and similar unprepared foods purchased for home consumption.
However, the exemption doesn't extend to prepared foods, candy, carbonated beverages, or alcoholic beverages. Restaurant meals and takeout food remain fully taxable, as do snack foods and similar convenience items.
Prescription medications and certain medical devices are exempt from Connecticut sales tax, helping reduce healthcare costs for consumers. Over-the-counter medications generally remain taxable unless specifically exempted.
Connecticut offers several exemptions designed to support business operations and economic development. Raw materials that become components of manufactured products can be purchased exempt from sales tax when proper documentation is provided.
Manufacturing equipment and machinery used directly in production processes may qualify for exemptions under certain circumstances. The equipment must be integral to the manufacturing process rather than used for general business operations.
Research and development activities benefit from various exemptions, reflecting Connecticut's focus on encouraging innovation and technology development within the state.
Businesses purchasing items specifically for resale can use proper exemption certificates to avoid paying sales tax on those purchases. Connecticut requires the use of specific exemption certificates that must be properly completed and maintained by both buyers and sellers.
The resale exemption only applies to items purchased specifically for resale in the ordinary course of business. Items purchased for business use, even by retailers, don't qualify for resale exemptions and are subject to sales or use tax.
Proper documentation is crucial for resale exemptions. Sellers must obtain and maintain valid exemption certificates, while buyers must ensure they're only using certificates for qualifying purchases.
Once registered, Connecticut businesses must file regular sales tax returns using the myconneCT online system. The Connecticut Department of Revenue Services requires electronic filing and payment for all sales tax returns, eliminating paper filing options.
Most businesses are assigned monthly filing frequency, with returns due on the last day of the month following the reporting period. For example, January sales are due February 28th, February sales are due March 31st, and so forth.
Connecticut's mandatory electronic filing system provides immediate confirmation and typically processes payments faster than traditional methods. The system integrates filing and payment functions, making compliance more efficient.
Payment options include direct electronic transfer from bank accounts (no fee) and credit card payments (convenience fees apply). Electronic payments made by the due date are considered timely, and the system provides confirmation numbers for record-keeping.
Even businesses with no taxable sales must file returns for their assigned periods. Failure to file returns, even when no tax is due, can result in penalties and compliance issues with the DRS.
Use tax complements Connecticut sales tax by covering situations where sales tax wasn't collected at the time of purchase. This commonly occurs with out-of-state purchases, online purchases from vendors without Connecticut nexus, and items brought into Connecticut from other states.
The use tax rate equals the applicable sales tax rate – typically 6.35% but potentially different for items subject to special rates. Use tax is reported on your regular sales tax return, making compliance relatively straightforward.
Businesses frequently encounter use tax obligations when purchasing equipment or supplies from out-of-state vendors who don't collect Connecticut sales tax, buying items online from vendors without Connecticut presence, acquiring vehicles or equipment from dealers in other states, or importing goods from international suppliers.
Maintaining detailed records of all purchases where Connecticut sales tax wasn't collected helps ensure accurate use tax reporting. The DRS examines these transactions during audits to verify proper compliance.
Connecticut periodically offers sales tax holidays that temporarily exempt certain items from sales tax. The most notable is the annual Sales Tax-Free Week, typically held in August before the school year begins.
During the Sales Tax-Free Week, clothing and footwear under $100 per item are exempt from sales tax. School supplies and instructional materials also qualify for exemption during this period, helping families prepare for the new school year.
Businesses must adjust their point-of-sale systems to properly handle exempt items during sales tax holidays. The holidays require careful attention to the specific items and dollar limits covered by each exemption period.
Items above the exemption thresholds remain subject to sales tax during holidays. For example, during Sales Tax-Free Week, a $150 pair of shoes would be taxable while a $75 pair would be exempt.
Connecticut offers various special programs that can affect sales tax obligations for qualifying businesses. These programs support economic development goals while providing competitive advantages for eligible operations.
Connecticut provides sales tax exemptions for machinery, equipment, and materials used in biotechnology industries. Companies must complete proper certification forms to claim these exemptions, but the savings can be substantial for qualifying operations.
High-technology companies may qualify for exemptions on computer equipment and related technology purchases when used for qualifying activities. These exemptions support Connecticut's efforts to maintain its position in technology and innovation sectors.
Connecticut's agricultural sector benefits from various sales tax exemptions on items used exclusively for agricultural production. Farmers must obtain current Farmer Tax Exemption Permits to claim these benefits.
Commercial fishing operations can purchase vessels, equipment, and related items exempt from sales tax when proper permits are maintained. These exemptions support Connecticut's coastal economy and traditional industries.
Successful Connecticut sales tax compliance requires establishing reliable systems and maintaining proper documentation. The state's electronic filing requirements and audit practices emphasize the importance of accurate record-keeping.
Connecticut requires businesses to maintain detailed records of all sales transactions, including both taxable and exempt sales. Exemption certificates must be properly completed and maintained for all exempt transactions.
Records should include sales invoices, exemption certificates, purchase records for use tax purposes, and documentation supporting any claimed exemptions. The DRS recommends keeping records for at least four years to cover potential audit periods.

Connecticut sales tax laws and rates can change, though the uniform statewide structure provides more stability than states with complex local tax systems. The Connecticut Department of Revenue Services provides regular updates on law changes and compliance requirements.
The DRS offers webinars and educational sessions on various compliance topics, helping businesses stay informed about requirements and best practices. These resources are particularly valuable when the state implements new requirements or modifies existing procedures.
