Hello,
Small dental office C-Corp advised by accountant 14 years ago for NOL. Currently operating part-time with spouse & myself as W-2 employee. Equipments fully-depreciated, no more carryover NOL, brand new SBA-EIDL loan (started paying July 2024 due to 2-yr deferred payments). Does it make sense to convert to S-Corp (LLC?) and do I need to make a new QB business account?
Converting to an S-corporation may have some other implications. Built-in gains tax. Businesses that convert from a C corporation to an S corporation might owe the built-in gains tax. This tax is imposed if the S-corp sells assets within five years of the conversion that had increased in value while it was a C corporation. The tax is calculated on the increased value that was "built-in" at the time of the conversion. Although you mentioned fully depreciated assets if you sell your practice there could be tax implications.
The main advantage of pass-through taxation is that the business itself generally isn’t subject to federal income tax. This helps avoid the “double taxation” commonly associated with C corporations, where income is taxed at both the corporate level and again at the shareholder level when dividends are distributed. I do recommend you consult with legal before making any determination. Here are further details: S Corp Taxes
