After you file

If you live in Florida, since this is not a community property state, then the tax benefits would depend on other things such as how you file, your overall tax situation and if he materially participates in the LLC.  If you file a joint return, there may be no tax benefits at all since the income will still be reported on your joint return depending on his participation level.

If you file separately, and he has additional income, this could have him pay more in taxes.  If he has no other income, it may not have any affect at all on your overall tax situation.
 

It would greatly depend on if he materially participated in the LLC.  If he does not, then this would be investment income on his side and his portion would not subject to Self-Employment Tax, whereas yours would be since you would be materially participating. 

"Material participation tests.

You materially participated in a trade or business activity for a tax year if you satisfy any of the following tests.

• You participated in the activity for more than 500 hours.
• Your participation was substantially all the participation in the activity of all individuals for the tax year, including the participation of individuals who didn’t own any interest in the activity.
• You participated in the activity for more than 100 hours during the tax year, and you participated at least as much as any other individual (including individuals who didn’t own any interest in the activity) for the year.
• The activity is a significant participation activity, and you participated in all significant participation activities for more than 500 hours. A significant participation activity is any trade or business activity in which you participated for more than 100 hours during the year and in which you didn’t materially participate under any of the material participation tests, other than this test. See Significant Participation Passive Activities under Recharacterization of Passive Income, later.
• You materially participated in the activity (other than by meeting this fifth test) for any 5 (whether or not consecutive) of the 10 immediately preceding tax years.
• The activity is a personal service activity in which you materially participated for any 3 (whether or not consecutive) preceding tax years. An activity is a personal service activity if it involves the performance of personal services in the fields of health (including veterinary services), law, engineering, architecture, accounting, actuarial science, performing arts, consulting, or any other trade or business in which capital isn’t a material income-producing factor.
• Based on all the facts and circumstances, you participated in the activity on a regular, continuous, and substantial basis during the year.

You didn’t materially participate in the activity under test (7) if you participated in the activity for 100 hours or less during the year. Your participation in managing the activity doesn’t count in determining whether you materially participated under this test if:

• Any person other than you received compensation for managing the activity, or
• Any individual spent more hours during the tax year managing the activity than you did (regardless of whether the individual was compensated for the management services).

Participation.

In general, any work you do in connection with an activity in which you own an interest is treated as participation in the activity." Publication 925
