Are you claiming the deductions you deserve?

If you own your own business, you might want to consider these five deductions that could save you thousands.

1. Home Office Deduction: If you run your business from your residence, you can deduct a portion of your rent, mortgage interest, utilities, internet, and more.
2. Vehicle and Mileage: If you use your car for business purposes, you can deduct exact expenses like gas, insurance, repairs, and depreciation or use the IRS standard mileage rate.
3. Business Meals: If you take clients or prospects out for meals, or travel for business reasons, you may be able to deduct up to 50%. It’s crucial, however, to keep records of the date, place, attendees, and purpose of each meal.
4. Equipment and Supplies: Purchases like computers, software, furniture, machinery, and more can often be fully deducted in the same year of the purchase.
5. Retirement Contributions: You can deduct contributions to your employees’ retirement plans, and even your own if you’re self-employed.
