(Focusing on the US) So, how do you deal with tax (and on a side note, accounting?) If I remember correctly, YC companies are incorporated as C corps (which means both double taxation and a bit of hassle with IRS forms and such.)
More specifically, what does your company do with the profits at your company that are distributed to the founders? In other words, do you keep all the cash inside the company accounts and pay out a small living salary? Do you pay dividends based on the equity table of the startup (and thus dividend tax comes in?) Do you have an accounting firm or just do it all yourself and throw it in EFTPS?
PG, if you're reading this: what do the YC companies do in terms of tax? Does YC have accounting firm connections, or do YC companies manage it by themselves?
Why am I asking this? Albeit being really important for startups that are incorporated to consider, I don't hear much about tax talked about here, for something that takes a minimum of 15% of your cash to the FDA^W IRS.
YC companies usually hire accountants when they raise enough money to. Before that the founders keep track of finances themselves using Quickbooks (or a shoebox full of receipts).
