If your bank feed hasn’t been touched since April, you can still have clean books by December 31. A nine month bookkeeping catch-up is usually a two to four week project once somebody has your statements, not the disaster it feels like at 11pm on a Sunday.

The pile is almost always smaller than owners think. The work is the same every time: match the money that moved, find what’s missing, and fix what got coded wrong in a hurry.

And nobody here is going to lecture you about it. Around Hagerstown, Williamsport, Smithsburg, Martinsburg, and Chambersburg, the owners who fall behind are usually the ones whose spring got busy. That’s the whole story.

What a catch-up actually involves, and what to gather

Catch-up work is reconciliation, not magic. Your bookkeeper rebuilds each month from the accounts the money ran through, then chases the handful of items the statements can’t explain.

Here’s what to pull together before you call anyone:

  • Bank statements for every business account, January through last month, as PDFs
  • Credit card statements, including the personal card you swore you’d stop using for supplies
  • Loan statements and the original loan documents, so principal and interest get split correctly
  • Payroll reports for each quarter, plus any contractor payments you made by check, Zelle, or cash
  • Invoices you sent that nobody has paid yet
  • Your 2025 tax return, so the opening balances match what was filed

That last one matters more than people expect. If your books start the year with balances that don’t agree with the return, every month after that is off by the same amount.

A week-by-week plan from late October to December 31

Ten weeks is enough time if you work backward from the deadlines instead of forward from the mess.

By whenWhat to get done
Late OctoberGather statements, give your bookkeeper read-only bank access, and list the accounts you forgot you had
Early NovemberReconcile January through June, flag every transaction nobody can identify
Mid NovemberSend W-9 requests to every contractor you paid this year, before holiday schedules start
Early DecemberReconcile July through November, review unpaid invoices and unpaid bills
Week of December 21Make the year-end decisions that need cash to move: equipment, bonuses, retirement contributions
January 5 to 15Reconcile December, then set your fourth quarter estimated payment, due January 15, 2027

The December week is the one people miss. A deduction you want for 2026 usually has to be paid or placed in service by December 31, so finding it on February 20 does nothing.

Three 2026 details that change how you rebuild your records

Mileage is the big one this year. The IRS business standard mileage rate for 2026 is 72.5 cents per mile for January 1 through June 30 and 76 cents per mile for July 1 through December 31. That means a reconstructed mileage log has to be split by trip date. One annual total at one rate is wrong no matter which rate you pick.

Contractor reporting changed too. The One Big Beautiful Bill Act raised the Form 1099 reporting threshold from $600 to $2,000 for payments made after December 31, 2025, with inflation indexing for calendar years after 2026. So for 2026 payments, fewer of your subs will need a form. Collect the W-9 anyway, because you don’t know in October who crosses $2,000 by December.

Then there’s the date. The statutory 1099-NEC deadline is January 31, and Form 1099-NEC is due February 1, 2027 for both IRS and recipient copies, since January 31, 2027 falls on a Sunday. You cannot produce accurate 1099s from unreconciled books, which is why January panic is usually a bookkeeping problem wearing a tax costume.

What clean books mean in Maryland, Pennsylvania, and West Virginia

Our clients cross state lines constantly, and the paperwork does not travel with them.

In Maryland, your entity owes an annual filing whether or not it made money. The Form 1 deadline is April 15, and the filing fee for most business entities is $300.

Maryland law exempts business personal property from valuation and taxation if its total original cost statewide is under $20,000, an exemption that has applied to tax years beginning after June 30, 2022. You still file. And you can only answer the $20,000 question if your fixed asset list is current, which is exactly what nine months of skipped bookkeeping destroys.

Maryland sales tax has its own rhythm. Returns are due on the 20th day of the month following the end of the period, moving to the next business day when that lands on a weekend or holiday, so Q4 filers are looking at January 20, 2027. If you sell software or IT services, check your invoices before you file: Maryland’s 3% sales and use tax on certain data and IT services took effect July 1, 2025.

Sell in Berkeley County and the rate changes on you. Martinsburg has imposed a 1% municipal sales and use tax since July 1, 2015, for a combined rate of 7%. If your point of sale has been charging 6% on Martinsburg jobs all year, your catch-up just became a sales tax correction.

Have one employee at a Chambersburg or Greencastle worksite? Pennsylvania’s Act 32 applies to you. Employers must withhold local earned income tax from residents and nonresidents, withholding the higher of the employee’s total resident rate or the nonresident rate where they work, and remit to the workplace tax collector. In Franklin County, that collector is the Franklin County Area Tax Bureau. Those quarterly returns are easy to forget when the books are cold.

One more local number worth knowing before you set a January estimate: Washington County’s local income tax rate is 2.95% for the 2026 tax year, on top of Maryland state tax. That stacks with federal and self-employment tax on every dollar of profit your books report.

What a cleanup usually turns up

Here’s a composite example, with made-up numbers, for a Hagerstown lawn and landscape LLC taxed as a sole proprietorship, books untouched since April.

What the cleanup foundEffect on 2026 profit
Supplies and fuel bought on the owner’s personal card$4,260 of deductions added
Mileage, Jan 1 to Jun 30: 1,420 miles at 72.5 cents$1,029.50 added
Mileage, Jul 1 to Dec 31: 1,380 miles at 76 cents$1,048.80 added
A $12,000 equipment loan deposit recorded as sales$12,000 of overstated income removed
Total correction$18,338.30 lower profit

At roughly 30 cents on the dollar in combined federal income tax, self-employment tax, Maryland tax, and Washington County’s 2.95%, that’s about $5,500. Your number will be different. This example assumes a sole proprietor in the 12% federal bracket with no other income, and it ignores the cost of the cleanup itself.

Notice where the money actually came from. Two thirds of it was a loan recorded as revenue, which is the single most common error we see in books that stopped getting reconciled. The mileage split, by comparison, is worth $48.30 against the lazy version where all 2,800 miles get the 72.5 cent rate.

When catching up before December 31 isn’t worth it

If you’re closing the business this year and have already stopped taking work, a full cleanup of every month is probably money you don’t need to spend. Reconstruct enough for an accurate final return and move on.

If you haven’t filed 2025 yet, fix that first. Catching up 2026 on top of an unfiled prior year means your opening balances are guesses, and you’ll pay to do the same work twice.

And if you have maybe 200 transactions in one checking account with no payroll, no inventory, and no sales tax, you can likely do this yourself in two long evenings. Download the statements, categorize, reconcile, done. Paying someone makes sense when there’s payroll, contractors, multiple states, loans, or a year of personal and business spending mixed together.

The honest limit: catching up does not reduce tax you genuinely owe. It stops you from paying tax you don’t owe, and it stops the penalties that come from filings you didn’t know about.

Frequently asked questions

How long does it take to catch up nine months of books?
For most small businesses here, two to four weeks from the day we get statements and bank access. Volume, payroll, and missing records are what stretch it.

What if I don’t have my receipts?
Bank and card statements carry most of the load, and vendor history fills in a lot of the rest. Some categories, like travel and meals, need more detail than a statement line, so keep what you do have.

I’m behind in Maryland and I have one employee in Chambersburg. What else might be late?
Quarterly local earned income tax returns with the Franklin County Area Tax Bureau, plus your Pennsylvania state withholding and unemployment filings. Those run on their own calendar and don’t pause because your books did.

Do I still need to send 1099s if I paid a sub $1,500 this year?
Federally, the 2026 threshold is $2,000 per payee, so that one likely doesn’t need a form. Get the W-9 anyway, and check state rules, because some states did not follow the federal increase.

Is it too late to start in December?
No, but you lose the year-end moves. Anything that needs cash to leave your account, like equipment or a retirement contribution, has to happen before December 31.
