A working playbook for mobile mechanic bookkeeping — tiered labor rates, a parts markup matrix targeting 58% gross margin, actual-expense vs 72.5-cent standard mileage, Section 179 on scan tools and upfitted cargo vans, comeback warranty reserves, and quarterly Schedule C obligations.
Section 736 splits liquidating payments to a retiring partner into 736(b) property payments (capital gain, no firm deduction) and 736(a) income or guaranteed payments (ordinary income with self-employment tax, deductible by the firm).

Section 107 lets ordained ministers exclude designated housing costs from federal income tax, but the allowance is still added back for SECA and only an in-advance written designation survives audit.
