Upgrade to Tax & AccountingBookkeeping Firm


Whether you are filing personal taxes or you own a business, if you are not already using a professional tax and accountingbookkeeping firm, you have most likely already missed out on major tax benefits, deductions and credits. This is because a professional tax and accountingbookkeeping firm utilizes licensed professionals, who can not only advise individuals on personal financial matters but who are qualified to advise businesses, financial institutions, nonprofit organizations and government agencies on a wide range of financial topics. Our strict standards ensure that we understand the complicated tax laws and how to implement strategies that return the most benefits to individuals and businesses.

Amendments

It is not uncommon to come across a significant deduction or error that was overlooked when you filed taxes. When this happens, the Internal Revenue Service allows you the opportunity to retroactively amend your taxes to rectify such errors. Whether you received a revised 1099, overlooked a sizable charity deduction, or even miscalculated your mortgage interest, amending your tax return can help you recover the money you are rightfully owed.

At Paramount Tax and AccountingBookkeeping, we not only help you amend your taxes, but also:

  • Calculate your estimated refund
  • Identify reasons (if any) NOT to amend
  • Determine the timing of filing an amendment
  • Determine whether amending your taxes is worth the time and investment

Although there are no requirements or penalties for not filing an amendment, our tax return specialists at Paramount Tax & accounting can help you best understand.
