The first day for Individual 1040 tax filings was January 24th with not all Federal and state forms ready – those will continue to become available throughout February. The last day for filing without an extension will be April 18, 2022 due to Good Friday and the weekend. Any changes in these dates will be posted at

Important Note

If documents are submitted after April 1, tax returns will be automatically extended.  They may still be completed by the deadline, but there is no guarantee as this late date

Our door drop slot or an online platform, such as Dropbox or Google Drive, will be the best way to deliver your tax documents.  When visiting the office or dropping off documents in person, please ask for any prior tax documents if you have not yet picked them up.
