“Excellent experience with Welfo LLC. As someone who just moved to the US, I had no idea where to start, but they helped me set up my LLC, get Gusto payroll running, and handled all my tax planning and filings with real expertise.”
“I consulted with WELFO about business formation and tax planning. They explained different options for my future company, including LLC vs S-Corp, with clear tax projections. I appreciated the honest approach. There was no upselling. They gave practical advice on how to set things up right and make the business more profitable. I plan to move my accounting to them.”
“They didn’t just hand me a pile of papers; they actually dug into the guts of my business. They provided more than just basic reports. They gave me valuable insights on tax optimization. They also helped me fix gaps in our documentation that I hadn’t noticed. If you want a partner, not just an accountant, these are the guys to talk to.”
“This was an especially complicated tax year for us — multiple states, stock transactions, bonuses, and two separate businesses — and they handled everything flawlessly. I truly appreciated not only the technical expertise, but also the strategic advice and ability to navigate complex situations with confidence.”
“Welfo helped me with a very complicated tax return that included foreign income and foreign assets, part-year residency, and multiple income sources. The CPA took the time to clearly explain IRS requirements, options, and potential risks, which gave me real peace of mind. Everything was filed accurately and on time.”
“I received an IRS notice and was very stressed. Another firm quoted an extremely high fee. I contacted WELFO for a second opinion and they quickly reviewed my case, explained my options, prepared the response, and charged a reasonable price. The issue was resolved with no penalties.”
Clear terms before we start, and responsibility for our work after we finish.
