I will begin receiving income for my new small business starting in early June. This will be my first year paying estimated quarterly taxes. Without vouchers from TurboTax, how do I go about making payments? Additionally for the first quarter in which I owe (June 15th), what's the best way to estimate taxes given the short period that I will receive income. I'm familiar with the safe harbor requirement and had planned to simply divide up 110% of last year's taxes across the quarters, but for the first quarter in which I receive income (Q2 of 2022), I may need to prorate differently as my income will be much lower since I'll only have a week or two under my belt.
