Section 179 of the Internal Revenue Code allows businesses to deduct the full purchase price of qualifying equipment and software up to an annual limit.In 2024, for example, taxpayers can expense up to $1,220,000 of qualified assets.This election can apply to many types of tangible personal property, such as machinery, equipment, and off-the-shelf software, which are used predominantly in your business.Limits on Section 179 ExpensingAs attractive as Section 179 may seem, there are limits.For tax year 2024, the maximum investment limit is set at $3,050,000.If your business places more than this amount in service, the amount you can expense is reduced dollar-for-dollar over this threshold.In addition to the dollar and investment limits, the amount of your Section 179 deduction cannot exceed your taxable business income for the year.This means that even if your business invests heavily in qualified property, the deduction could be limited by the business’s profitability.Also, not all property qualifies for Section 179.Real property, like buildings and structural components, generally does not qualify unless it is "qualified improvement property."

As far as the Tech Stack goes, a common mistake is not considering what future tech you want to use, then you're stuck with things that don't integrate (API out) to it, and you get really limited in future options. 

City of Madison recently really increased there occupancy limits. 

At the end of the day, you didn't start your business to be a bookkeeper, so my advice is to focus limited time & energy on the things that you love & excel at! 

Could you expand on what you mean by limiting your risks?
