Important Notices
Connecticut Requires Tax Preparer Registration
Connecticut is one of the few states that regulates tax preparers. Preparers filing 10+ CT returns or 10+ federal returns for CT taxpayers must obtain permit from DRS. Penalties for operating without required permit. Verify requirements at https://portal.ct.gov/DRS
IRS PTIN is Mandatory
Anyone who prepares or assists in preparing federal tax returns for compensation must have a valid PTIN from the IRS. Preparing returns without a PTIN is illegal and can result in penalties. Renew annually before each tax season.
Consider Becoming an Enrolled Agent
An Enrolled Agent (EA) is the IRS's highest credential for tax professionals. EAs have unlimited representation rights before the IRS, can represent clients in audits and appeals, and command higher fees. The 3-part Special Enrollment Exam is challenging but career-changing.

Start Seasonal, Expand Year-Round
Most new tax preparers in Connecticut start as seasonal operations (January-April). As you build your client base, add year-round services: tax planning, bookkeeping, payroll, and quarterly estimated tax preparation. Year-round services create steady income beyond tax season.
Become an Enrolled Agent
The EA credential is the best investment a tax preparer can make. It gives you unlimited IRS representation rights, commands higher fees, and differentiates you from uncredentialed preparers. Study 3-6 months, pass 3 exams, and your earning potential jumps 30-50%.
Focus on Client Retention
Tax prep is a recurring business—clients return every year if you do good work. Send reminders in January, offer prior-year return discounts, and provide year-round tax tips. A Connecticut practice with 200+ returning clients generates strong seasonal income.
Offer Tax Planning Services
Tax planning (not just preparation) commands premium fees. Help Connecticut clients minimize their tax liability through strategic planning, retirement contributions, business deductions, and timing of income/expenses. Charge $225-$1125 for an annual tax planning session.
Connecticut Tax Prep Tips
Get Your IRS PTIN
Apply for your Preparer Tax Identification Number at irs.gov/ptin. It costs $19.75 and takes about 15 minutes online. You must renew annually before each tax season. This is the minimum federal requirement to prepare returns for pay.
Complete Connecticut Registration Requirements
Connecticut requires permit required. Preparers filing 10+ CT returns or 10+ federal returns for CT taxpayers must obtain permit from DRS. Complete this before your first tax season.
Get Tax Education & Consider EA Certification
Complete tax preparation training through an accredited program. Consider becoming an IRS Enrolled Agent (EA)—pass the 3-part Special Enrollment Exam for unlimited IRS representation rights. EA certification significantly increases your earning potential and credibility in Connecticut.
Register Your Business
File LLC ($120) with Connecticut Secretary of State. Get EIN from IRS (free). Apply for EFIN (Electronic Filing Identification Number) to e-file returns. Open a business bank account.
Purchase Tax Software
Choose professional tax software: Drake Tax ($1,500-$3,000/season), Lacerte ($400-$4,000), ProSeries ($500-$2,000), or UltraTax. Most Connecticut preparers start with Drake or ProSeries for the best value. Ensure your software handles both federal and Connecticut state returns.
Get Insurance & Bonding
Professional liability (E&O) insurance is critical—one error on a return can lead to costly client claims. Budget $450-$1350/year in Connecticut.
Set Up Your Office
Set up a secure workspace with a reliable computer, printer/scanner, shredder (for sensitive documents), and locked filing for client records. Many Connecticut preparers start from home offices during January-April and expand later.
Build Your Client Base
Start marketing in November/December before tax season. Offer early-bird discounts in Connecticut. Partner with bookkeepers, financial advisors, and real estate agents for referrals. Register on Google Business Profile and local directories. Word-of-mouth from satisfied clients is your best long-term growth strategy.
