Deductions and Credits

Knowing what deductions and credits are available can significantly impact the amount of taxes owed or refunded.

Electronic Filing

E-filing is a convenient and secure way to submit tax returns, reducing processing time and the risk of errors.

IRS Penalties and Consequences for Non-Compliance

If taxes owed are not paid by the deadline, penalties and interest will accrue on the outstanding amount.

Accuracy-Related Penalties

Criminal Penalties

Engaging in deliberate tax evasion or fraud can lead to criminal charges, fines, and even imprisonment.

Dealing with IRS Disputes and Appeals

Tax Court

Taxpayers can take their cases to the United States Tax Court if they remain dissatisfied after going through the appeals process.

Tax Scams and How to Avoid Them

Phone Scams
