As you complete your tax return, please verify you have a current account number indicated for the tax refund to be deposited to or your payment to be withdrawn from.  This is critically important for our La Crosse area members who will need to update their FSCU account information to MEFCU account information. Please note the routing number for MEFCU is 291975478.  If you do not update this information with your tax preparer or in your tax software, your transaction will attempt to post and potentially reject and be returned or require significant research and a delay in the funds being deposited to your account. Thank you for your prompt attention to this matter.
