Tax considerations when adding a new partner at your business

Adding a new partner in a partnership has several financial and legal implications. Let’s say you and your partners are planning to admit a new partner. The new partner will acquire a one-third interest in the partnership by making a cash contribution to it. Let’s further assume that your bases in your partnership interests are sufficient so that the decrease in your portions of the partnership’s liabilities because of the new partner’s entry won’t reduce your bases to zero.

Tax issues to assess when converting from a C corporation to an S corporation

Operating as an S corporation may help reduce federal employment taxes for small businesses in the right circumstances. Although S corporations may provide tax advantages over C corporations, there are some potentially costly tax issues that you should assess before making a decision to switch.

Here’s a quick rundown of the most important issues to consider when converting from a C corporation to an S corporation:

What charitable givers need to know about taxes

Although most charitable donors aren’t primarily motivated by potential tax breaks, they still need to know how donations affect their taxes. It’s important for your not-for-profit to educate them — particularly as tax laws change. For example, in 2020 and 2021, even nonitemizers were allowed to deduct up to $300 and itemizers could deduct cash gifts up to 100% of their adjusted gross income (AGI).

Like many people, you may have dreamed of turning a hobby into a regular business. You won’t have any tax headaches if your new business is profitable. But what if the new enterprise consistently generates losses (your deductions exceed income) and you claim them on your tax return? You can generally deduct losses for expenses incurred in a bona fide business. However, the IRS may step in and say the venture is a hobby — an activity not engaged in for profit — rather than a business. Then you’ll be unable to deduct losses.

Making your return to in-person fundraising successful

It’s been a long two years. But many not-for-profits are starting to plan in-person galas and other special events for this coming summer and autumn. If your organization is trying to get back to “normal” with a face-to-face fundraiser, understand that it’s likely to be more challenging to plan than in the past.
