Kelsie Pelster

Hi, I'm Kelsie! Founder of KPA Services and I specialize in bookkeeping and accounting for self-employed professionals and small business owners who are tired of feeling behind on their finances.

I created this calculator because I've seen firsthand how a surprise tax bill can throw off everything you've worked hard to build. You shouldn't have to wait until April to find out where you stand. This tool gives you a simple, clear starting point - completely free - so you can plan ahead with confidence and keep more of what you earn.

No spam, ever. Just your free calculator and a few helpful tips from Kelsie!
