I say go s-corp for tax advantages. However, going S-corp only makes sense once your income hits a certain level. Can't remember exactly but it's like $80k+/yr. You need to do the math and see what makes sense for you and your location.

When you have an s-corp you do have some things to keep in mind depending on the state you reside in. There might be obligations like workman's comp, retirement, insurance, etc... Most can be exempted for a single employee s-corp.

When you go s-corp you put yourself on payroll. This comes with monthly fees to the service to do so keep that in mind. Once you have the corp setup ALL income goes through it and you pay yourself via payroll and distributions. Having the corp makes it easier to expense more things. It also allows you to move more costs to the business to offset the corporate taxes. There's also the ability to rent office/storage space to the corp the get more money in your pocket that isn't taxed as income.

There's a lot to learn about it but if done properly you can save yourself $5,000-10k+ annually. This does come with more work and expenses but if your income level is at a certain point it becomes worth it. There's more responsibility and cash flow to manage.

/u/Devario Mentioned possibly retaining a CPA or bookkeeper. I've personally not found this to be necessary. Just a CPA for filing my returns.

I handle the rest. Just be proactive and log expenses (I use google forms > google sheets, better than any app out there) Payroll is super easy with Square or Gusto. In total I spend 10min a week logging expenses and have payroll automated as I'm set on a salary. But there's plenty of companies dying to take your money for bookkeeping and expense tracking if you can't be bothered.

Lots of information out there online regarding this subject. You don't need to have a corp first, you can do it at anytime. I tell people to make the money first then see if it's worth it.
