I have a full time job and also have a side gig. I understand I need to pay self employment tax through my single member LLC on estimated quarterly taxes. If I cap out my Social Security and Medicare contribution in the tax year through my full time employer, do I calculate my self employment tax based upon the assumption that my LLC revenue is a separate cumulator than my full-time position OR do I treat it was a combined cumulator between full time role (separate from my LLC) and side gig until I reach my combined 2024 max for the year? When I reach the max contribution, do I still pay estimated quarterly tax payments?
