Key Corporate Tax Changes for 2025
Recent legislation (the "One Big Beautiful Bill Act") has introduced major changes for businesses for the 2025 tax year. The most significant updates include:
- Permanent 100% Bonus Depreciation: Businesses can once again immediately expense 100% of the cost of qualified new investments.

Common Refund Questions
- Why is my refund delayed? The most common reasons include: minor typos or miscalculations, incorrect or incomplete forms, potential identity fraud, or your refund being garnished for outstanding debt.
- Will the IRS contact me? The IRS will *always* contact you by mail first. Unsolicited calls or emails are scams.
- What tax breaks cause delays? If you claim the **Earned Income Tax Credit (EITC)** or the **Additional Child Tax Credit (ACTC)**, the IRS is legally required to hold your *entire* refund until mid-February. You can expect to receive these refunds in early March.
- What if I file an extension? An extension gives you more time to file (until October 15, 2026), but it is **NOT** an extension to pay. Your tax payment is still due by April 15, 2026.
