Quarterly Deadlines and Hours
We work extended hours leading up to the quarterly deadlines on February 15th, May 15th, August 15th and November 15th. Our extended filing deadline hours will be posted at the top of your Control Panel page. Please avoid the rush and add signers or ask your questions early.
Tax Advice
We cannot provide tax advice for your return. If you run into a problem entering your data into our system, we would be glad to help. Detailed instructions for each IRS tax-exempt form can be found online through the IRS. If you need professional tax help we recommend contacting a CPA who is familiar with tax-exempt filings, or visit the IRS Directory of Federal Tax Return Preparers with Credentials and Select Qualifications: http://irs.treasury.gov/rpo/rpo.jsf.
