Tax Planning Services in NJ: What to Do Before December 31, 2026

What a tax planning service is, and how it differs from tax preparation

A tax planning service looks forward. Before the year ends, someone projects your income and tax, then tests the choices that change it: how much to put into retirement accounts, when to sell investments, whether to give to charity this year or next, how a business pays its owners, and which state elections to make. Tax preparation looks back. After the year ends, it reports what happened on the return.

The IRS describes it the same way when it explains preparer credentials. It says “some CPAs specialize in tax preparation and planning,” that some attorneys do too, and that the exam enrolled agents pass covers “federal tax planning, individual and business tax return preparation, and representation.” Planning and preparation are often sold by the same firm, but they are different work done at different times.

The December 31, 2026 checklist for New Jersey filers

These moves only count for 2026 if they happen in 2026. Every figure comes from the IRS or the New Jersey Division of Taxation page named in the source column, read October 26, 2026. Whether a move helps you depends on your own return, which this page cannot see.

• Donations to donor-advised funds generally do not qualify for the new non-itemizer deduction, according to IRS Publication 6196.
• The first RMD can wait until April 1 of the year after you reach 73, the IRS FAQs say, but the second is then due by December 31 of that same year.
• 401(k) money comes out of pay, so only the paychecks left in 2026 can raise this year's total. Ask your employer's payroll or plan contact how fast a change takes effect.

The full NJBEST rules, including the $200,000 test and the line 37a entry, are in the NJ 529 tax deduction guide.

What can still wait until 2027

Not every 2026 move ends on December 31. These have later deadlines, which is why a planning meeting in November or December still has room to work after New Year's Day.

How to make the January 15, 2027 payment online or by mail, and the interest New Jersey charges when estimates fall short, are in the NJ estimated tax payments guide.

Whether the BAIT election pays for your business, and how the 2026 federal SALT cap changes that, is covered in the NJ BAIT tax guide.

Tax planning for small business owners and new businesses

Owners have the most decisions to time, because the business and the owner file separate returns that affect each other. For a New Jersey partnership or S corporation, the BAIT election is the largest state choice: the entity can pay New Jersey tax on its owners' share of income, and the owners claim a credit. The Division's FAQ says the election is made every year and “cannot be made retroactively.”

A new business has a short list of first-year choices. If an owner wants a corporation or eligible LLC taxed as an S corporation from January 1, 2027, the IRS instructions for Form 2553 say it can be filed during 2026 or no later than 2 months and 15 days into 2027, which the IRS itself works out as March 15. Anyone who pays an independent contractor will also need Form 1099-NEC by January 31.

Owners without an employer plan can still save for retirement after year-end. A SEP can be set up and funded as late as the due date of the business's return, including extensions, the IRS says, up to 25% of compensation or $72,000 for 2026.

• Estimated tax: New Jersey requires estimated payments if you expect to owe more than $400 after withholding and credits; the federal 2026 Form 1040-ES uses $1,000.
• Owner pay, entity choice and equipment purchases change the return in ways that depend on full facts. Ask the CPA to show both versions with figures before you decide.

Tax planning for high income earners

Higher incomes hit more of the limits that phase out, so the same move can work for one household and not another. Three New Jersey and federal lines decide a lot in 2026.

Itemize or take the standard deduction in 2026?

Many year-end moves only help if you itemize. For 2026, the IRS sets the standard deduction at $32,200 for married couples filing jointly, $16,100 for single filers and married people filing separately, and $24,150 for heads of household. If your itemized deductions will land near that line, timing matters: a household can sometimes move deductible payments between years so it itemizes in one year and takes the standard deduction in the other.

The 2026 change for non-itemizers matters here too. Starting with tax year 2026, the IRS says people who do not itemize can deduct up to $1,000 of cash gifts to qualified charities, or $2,000 on a joint return. Gifts to donor-advised funds generally do not count for it.

What tax planning services cost

The fee survey this site uses is the National Society of Accountants' 2020–21 study, which reports a “Tax Services” category apart from return preparation. It averaged $174.29 an hour nationally, and $502 a month for firms that charge a fixed monthly fee. Those are survey averages from 2020 fees across CPAs, enrolled agents and other preparers, not a quote from any firm.

Planning is usually priced one of three ways: by the hour, as a fixed monthly fee, or bundled with return preparation. Ask which one before you share documents, and ask what a second meeting in December or a revised projection costs.

Return fees by form, hourly rates by service, monthly fees and New Jersey figures are set out in the CPA cost guide, with the survey years beside each number.

CPA, enrolled agent or tax preparer: who should do your planning?

The IRS groups tax professionals by credential. Certified public accountants are licensed by state boards of accountancy, enrolled agents are licensed by the IRS, and attorneys are licensed by state courts or bars. All three have “unlimited representation rights” before the IRS, which means they can represent you in audits, payment and collection issues, and appeals. Preparers without one of those credentials have limited rights.

For planning, the credential matters less than the fit. Ask whether the person plans for households or businesses like yours, whether they prepare the returns the plan affects, and whether they handle New Jersey's rules, such as BAIT and the NJBEST deduction. A New Jersey CPA's license, its status and any Board action can be checked in the state's own record in a few minutes.

Confirm a CPA's New Jersey license and any Board action with the NJ CPA license lookup guide.
