The dawning of 2019 means the 2018 income tax filing season will soon be upon us. After year end, it’s generally too late to take action to reduce 2018 taxes. Business owners may, therefore, want to shift their focus to assessing whether they’ll likely owe taxes or get a refund when they file their returns this spring, so they can plan accordingly.
With the biggest tax law changes in decades — under the Tax Cuts and Jobs Act (TCJA) — generally going into effect beginning in 2018, most businesses and their owners will be significantly impacted. So, refreshing yourself on the major changes is a good idea.
Taxation of pass-through entities
These changes generally affect owners of S corporations, partnerships and limited liability companies (LLCs) treated as partnerships, as well as sole proprietors:
- Drops of individual income tax rates ranging from 0 to 4 percentage points (depending on the bracket) to 10%, 12%, 22%, 24%, 32%, 35% and 37%
- A new 20% qualified business income deduction for eligible owners (the Section 199A deduction)
- Changes to many other tax breaks for individuals that will impact owners’ overall tax liability
