Possible Way to Beat the $10,000 Limit on Personal Tax Deduction

March 2nd, 2020 at 7:37 PM

C corporations cause double taxation for business owners, so you probably think you want to avoid them at all costs. 

And for many of you, this is true, as the S corporation often provides the lower overall tax outcome. 

But for some of you, the C corporation could provide the best tax outcome, especially since you can bypass the $10,000 state and local tax (SALT) deduction cap, which was introduced by the Tax Cuts and Jobs Act (TCJA), with a C corporation. 

Prior to the TCJA, you could deduct as itemized deductions on your Form 1040, Schedule A—without limit—the following foreign, state, and local taxes: 

Tax reform took two direct actions against your itemized deductions for foreign, state, and local taxes. Beginning in tax year 2018, 

If you operate your business as an S corporation, the S corporation passes its net income to your individual tax return. This causes you, the individual, to pay state income taxes on the S corporation income. Those state income taxes are subject to the $10,000 cap. 

C Corporation Loophole 

But there is an exception: This $10,000 limit applies only to individuals—meaning, taxes deducted on your Schedule A. The limit does not apply to C corporations. 

If you operate your business as a C corporation, then your C corporation pays state income taxes on its net income and deducts those taxes on its corporate income tax return. 

How on earth do you figure out which is best?
