Deducting Unamortized Startup Costs and Organization Costs When Closing a Business


If any unamortized start-up costs or organization costs remain on your books when your business is closed, deduct the balance remaining on your final return.

For example, if you elected to amortize organization costs over five years and you still have two years of unamortized organized costs remaining when your business is closed, deduct the remaining two-year balance on your final return.
