Several years behind is one file, quoted once
If you are several years behind on bookkeeping, the job is a reconstruction from the statements, not a monthly close you hope will catch the past on the way by. The only published fee is a $499 diagnostic. The rebuild is a fixed quote based on years behind and how many accounts are involved. A licensed CPA reviews the file before you see it.
Start at catch-up bookkeeping with a tax deadline. You approve the number in writing before production starts.
Why a per-year price would be fiction
Two businesses that are both "three years behind" are not the same file. One has two bank accounts and complete statements. The other has payroll, three cards, a merchant account, and a year of statements still at the bank. A public per-year band would ignore that. What catch-up bookkeeping costs is the longer version of why we will not publish one.
The one-year, two-year, and three-year posts are already written if you want the shape of a specific stack: 1 year behind, 2 years behind, 3 years behind. The rule in all three is the same. Statements first. Gaps named. No estimated months.
How far back the records usually go
Banks typically keep about seven years of statements. IRS recordkeeping guidance is what your preparer is measuring against. If the bank cannot produce a month, that month goes in a gap report. We do not invent the activity so the year looks finished.
Your preparer still files. We do not prepare the return and we do not contact the IRS.
What to send
Send statements for every account that moved money in the years that are behind, plus any existing file, even if it stops mid-year. What to gather first is the checklist.
