Questions

Connecticut tax FAQs

10 answers about taxes in Connecticut.

Do you prepare Connecticut state tax returns?

Yes. We prepare resident, part-year and nonresident Connecticut returns and file them with the Connecticut Department of Revenue Services, together with your federal return.

When are Connecticut individual returns due?

Many states follow the federal April 15 deadline, but some set their own dates. We track the Connecticut Department of Revenue Services deadlines for you and file extensions when they are needed.

Does Connecticut have a sales tax?

Yes. Connecticut charges sales tax, and local rates can add to the state rate. We help Connecticut businesses register, collect the right rate and file returns with the Connecticut Department of Revenue Services.

What payroll registrations does a Connecticut employer need?

Employers generally register with Connecticut for unemployment insurance and state income tax withholding, plus any other state payroll programs that apply. We handle the registrations and the ongoing filings.

Do I need to make Connecticut estimated tax payments?

If you have income without enough withholding, such as self-employment or investment income, Connecticut generally expects estimated payments during the year, with its own thresholds and due dates. We calculate federal and state payments together.

How are LLCs and corporations taxed in Connecticut?

Connecticut applies its own rules to LLCs, S corporations and C corporations, and in some cases charges franchise, gross receipts or minimum taxes regardless of profit. We review how your entity is treated in Connecticut before you form it or make an election.

I moved into or out of Connecticut. What do I file?

Usually a part-year return for each state you lived in during the year, with credits so the same income is not taxed twice. Our multi-state filing service handles this.

Can you represent me with the Connecticut Department of Revenue Services?

Yes. In addition to IRS matters, we respond to notices and audits from the Connecticut Department of Revenue Services when you authorize us to.

Can a Connecticut business work with BATS remotely?

Yes. We work with Connecticut businesses through video meetings, secure document upload and cloud accounting software, so there is no need to visit an office.

Which Connecticut cities do you serve?

We have dedicated pages for Bridgeport, Stamford, New Haven, Hartford, Waterbury, and we work with clients anywhere in Connecticut.
