Get help filing an appeal
After you send your details, we look for an independent appeal firm or attorney to take your case. We'll be in touch once one has agreed. Firms usually charge a share of what you save, and the one that takes it may pay LevyDay a referral fee.
LevyDay doesn't file appeals or give legal or tax advice. We only pass your details on. The independent firm or attorney that takes your case does the work and sets its own fee.
