CPA, tax accountant and bookkeeping for Martinez clients, delivered remotely

Sound familiar?

• Living or working across the state line

  Living in one state and working in another, moving during the year, or running a business with employees or customers across a state line can mean more than one state tax return.

  Martinez is in Columbia County, which borders South Carolina (U.S. Census Bureau county boundary files, 2023); about 6% of workers who live in Martinez work outside Georgia (American Community Survey 2019–2023 estimate; includes work in any other state).

• Your return is no longer simple.

  Investments, a rental property, a side business or income in another state. Brent prepares your federal and state returns and tells you up front what affects the price.

• Life changed this year.

  A move, a new job, a home purchase, a growing family. Changes like these can affect your return, and they are worth discussing when it is prepared.

• Switching accountants mid-year

  The books can be picked up from the start of any month. Many businesses switch after year-end or after filing, and a mid-year switch works too.
