I would like to Safe Harbor my estimated taxes but am a little confused with how my W2 taxes come into play. My understand is that I should:
1. Figure out how much I paid last year and divide by 4. This is how much I owe Uncle Sam each quarter.
2. Look at my W2 paystub and figure out how much I already paid in Federal and State taxes each quarter.
3. Subtract #2 from #1 and send a check to the IRS and State DOR.
Is this the proper steps? It seems easy enough.
As I recall, the very first year I had self-employed income I did no estimated taxes. Nothing. If I recall correctly, this is a relatively small sideline (approx $15K) you are starting, so the extra taxes won't be much, and you can pay them when you file your taxes. There will be a penalty/interest, but it won't be much. If you get your Solo 401(K) set up before the end of the year (put a minimum deposit in there to keep it open), you can dump the appropriate amount in after the year ends and you know exactly how much you can deposit.
After the first year, when you've been through everything and you know how much you are likely to earn, how to do the solo 401(k), etc you can start making your estimated tax payments. I don't bother trying to estimate every quarter what they should be--I just use the previous year's amount and divide by 4 to figure my quarterly payments.. There's a procedure for doing this--it comes with the tax software you probably use.
The "Elective Deferral" portion of your solo 401(K) PLUS your 403B contribution cannot exceed $16,500 in 2009. The other portion of your solo 401)K) contribution is called the "profit-sharing" portion, and it is limited to 20% (not 25%) of you net income from your side business (after subtracting 50% of the self-employment tax). This is not affected by the contributions you make to your 403b at work. It has a cap, but it is very high and you wont hit it unless your side business is making somewhere north of $100K.
a site where a question is answered similar to your question here.
I'd also recommend the Fidelity site referenced earlier.
Finally, when deciding between funding your solo 401K or your 403B, consider the choices you have in both areas. If you go ahead with the Vanguard Solo 401(K) you'll have tons of great low-cost investment options available.
Try not to make this too hard. All I'd do in your shoes right now is set up the solo 401(k) at Vanguard and then concentrate on my side business. I'd do that until March of 2010. Then I'd figure my taxes, make my investments into Vanguard for my Solo 401(k) and simultaneously start making my estimated tax payments for 2010. Throughout this year, squirtrell away money, because you'll need a lump of it in April 2010: To pay your 2009 taxes, to fund your solo 401(k), and to make your first estimated tax payment for the 2010 tax year.
