The Tax Cuts and Job Act abolished the Obamacare penalty on tax payers who were not covered by health insurance for 2019 and beyond. However, if you are covered by a health insurer through the Obamacare exchanges, they will send you a form 1095-A in early 2021, and we will need that form to correctly prepare your returns.

To assist taxpayers in deciding their withholdings claimed on their employers' W4 forms, the IRS provides a withholding calculator which we recommend all our clients utilize. The withholding calculator is available at this link:

Corporate Maintenance

We can help you file your company Annual Reports each year, and have a staff of experts that can help this process go as smoothly and as fast as possible.

Annual Minutes are yearly documents that record your company Annual Meeting information, which is to be held each fiscal year by the directors, even if it is just yourself. Included in these documents are: the date & location of your meeting, attendees, a summary of your company actions throughout the last fiscal year, and a statement as to what the company’s future resolutions are. Though they do not need to be reported, Annual Minutes must be documented in case an IRS audit were to occur. At Jeffrey D. O’Brien CPA, and Western Business and Tax Services we help you organize and file both Annual Reports and Annual Minutes.
